Water Cooled or Air Cooled Chillers
As per the critical purpose of a data center, all equipment must be reliable and easy to operate. It’s important to make sure the company’s focus can be on the critical nature of data center operations instead of HVAC (cooling) system management.
Water cooled chillers and air cooled chillers are refrigeration systems normally used to cool fluids or dehumidify air in both commercial and industrial facilities. The components of water cooled chillers and air cooled chillers are very similar. Each product contains an evaporator, condenser, compressor, and an expansion valve. The primary difference is whether air or water is used to provide the condenser cooling.
Water Cooled Vs Air Cooled
An air-cooled chiller has a condenser that is cooled by the environment air. The air-cooled chillers are preferred for small or medium installations but lately the quality improvement in their structure, allows the usage, in modular type, for large installations also. An air-cooled chiller is preferred especially in cases that there is not enough water or the water is very expensive.
The water-cooled chillers have water cooled condenser connected with cooling tower and are usually preferred for medium and large installations where there is sufficiency of water. In addition, they are also preferred in cases that is demanded constant performance of the system, independently of the ambient temperature (industrial air conditioning, air conditioning of digital systems etc), because the capacity of the water-cooled chillers are not affected by the ambient temperature fluctuations.
Flexibility
You may also note that air-cooled chillers have a much wider range in ambient operating temperatures. The wide ambient-temperature operating range allows designers' flexibility to standardize on chiller-plant designs, regardless of the data center location.
Redundancy and Effectiveness
Redundancy is essential for mission critical purpose-built data center. You should consider how long to bring the cooling system back to full load after power outages. In addition, the difficulties and cost effectiveness for installing 2N / N+1 cooling system should be carefully evaluated. Bare in mind water-cooled system should work with cooling towers and pumps.
System Maintenance and Downtime
Each chiller has basic maintenance requirements to ensure it functions at optimal levels. Though it is difficult to find a prefect cooling system with the lowest total cost of ownership (but competitive first costs), minimal operating & maintenance costs and a reduced risk of expensive downtime, we need to judged on the specific goals for every project.
Install Location
Large industrial chillers are commonly located in mechanical equipment rooms within the building close to the process in which they are cooling. Some industrial chillers may be located directly beside the process, depending on the size of the chiller and compressor. Some may even be placed completely outdoors such as rooftop of a building. Choosing which cooling system, therefore, largely depends on the building type, location, and use of the space.

10 Recommendations for your Data Center
When you are a data center manager or consulting-specifying engineer, very few things are more unsettling than the unexpected. We hope this list helps IT and engineering professionals better anticipate these issues and prepares them with the appropriate technologies, solutions, and best practices.
Generally speaking we have 10 advice for your data center:
High-density predictions finally come true
After rapid growth early in the century, projections of double-digit rack densities have been slow to come to fruition. Average densities hovered between 6.0 and 7.4 kW per rack from 2006 to 2009, but the most recent Data Center Users’ Group (DCUG) survey predicted average rack densities will reach 12.0 kW within three years. That puts a premium on adequate UPS capacity and power distribution as well as cooling to handle the corresponding heat output.
Servers may be replaced three times before UPS or cooling systems renewal
Server refreshes happen approximately every three years. Cooling and UPS systems are expected to last much longer—sometimes decades. That means the infrastructure that organizations invest in today must be able to support—or, more accurately, scale to support—servers that may be two, three, or even four generations removed from today’s models. Modular solutions can scale to meet both short- and long-term requirements. Engineers will need to consider and make the necessary adjustments and allocations regarding day-to-day servicing and maintenance of the longer lasting power and cooling equipment.
Down time is expensive
We don't want it. The most common causes of downtime are UPS battery failure and exceeding UPS capacity. Avoid those problems by investing in the right UPS—adequately sized to support the load—and proactively monitoring and maintaining batteries. This gives engineers an opportunity to share best practices with clients and recommend battery monitoring solutions and high-end availability architecture. They can use the cost of downtime information to support recommendations and ensure clients understand how they can implement design changes and modifications that will improve availability.
Energy rebates are available for energy efficiency upgrades
Many utility providers offer energy rebates and incentives for data centers that make energy efficiency improvements. This presents an opportunity for engineers to propose high-efficiency designs and help clients receive reimbursements for upgrading legacy equipment with high-efficiency power and cooling systems. Clients may also look to engineers to assist with the often lengthy application process. Once the reimbursement has been approved, utilities will request information on actual project costs and may require follow-up measurement and verification to determine actual energy savings.
Industry codes are playing a larger role in cooling strategy
In the 2010 edition of ASHRAE 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings, the SCOP (seasonal coefficient of performance) rating was expanded to include data centers. Codes are becoming more numerous and impacting data center cooling strategies and technology developments. It is important that engineers keep abreast of new codes and regulations and the latest technologies that enable compliance.
Monitoring can be a mess
IT managers have more visibility into their data centers than ever before, but accessing and making sense of the data that comes with that visibility can be a daunting task. According to an Emerson Network Power survey of data center professionals, data center managers use, on average, at least four different software platforms to manage their physical infrastructure. Of those surveyed, 41% say they produce three or more reports for their supervisors every month, and 34% say it takes three hours or more to prepare those reports. The solution? Move toward a single monitoring and management platform that can consolidate that information and proactively manage the infrastructure to improve energy and operational efficiency, and even availability.
IT Person may be in charge of the building’s HVAC system
The gap between IT and facilities is shrinking. Traditionally, IT and data center managers have had to work through facilities when they needed more power or cooling to support increasing IT needs. That process is being streamlined. For engineers, it is important that they now incorporate all of these players into the design process. Gone are the days when the engineer had to work with only one or two individuals, usually from the facility side. Now it is a complex ecosystem comprised of IT, operations, facilities, and sometimes procurement.
That patchwork data center needs to be a quilt
In the past, data center managers and engineers freely mixed and matched components from various vendors because those systems worked together only tangentially. However, the advent of increasingly intelligent, dynamic infrastructure technologies and monitoring and management systems has increased the amount of actionable data across the data center, delivering real-time modeling capabilities that enable significant operational efficiency. IT and infrastructure systems still can work independently, but to truly leverage the full extent of their capabilities, integration is imperative.
Data center on demand is a reality
The days of lengthy design, order and deployment delays are over. Today there are modular, integrated, rapidly deployable data center solutions for any space. Integrated, virtually plug-and-play solutions that include rack, server, and power and cooling can be installed easily in a closet or conference room. On the larger end, containerized data centers can be used to quickly establish a network or to add capacity to an existing data center.
IT loads vary a lot
Many industries see extreme peaks and valleys in their network usage. Financial institutions, for example, may see heavy use during traditional business hours and virtually nothing overnight. Holiday shopping and tax seasons also can create unusual spikes in IT activity. Businesses depending on their IT systems during these times need to have the capacity to handle those peaks but often operate inefficiently during the valleys. A scalable infrastructure with intelligent controls can adjust to those highs and lows to ensure efficient operation.

Data Center Tier Levels and Uptime
The data center industry is laden with inter-related terms such as Uptime, Tier Levels, Availability, Redundancy and Reliability. In order to make an informed decision it is important to understand what they mean and what is the actual significance for any proposals you are considering in your analysis.
The concept of “Uptime” was pioneered by the Uptime Institute which was founded in 1993 and introduced its well defined Tier Classification system: I, II, III and IV, of which Tier IV represents the highest level of projected availability. Today, its Tier Certification system is globally recognized and its members are mostly Fortune 100-sized companies having multiple data centers averaging 50,000 square feet. And while not everyone subscribes to the Uptime Institute officially, marketing references to Tier 2,3 or 4 are common among those seeking to ascribe a certain level of design or construction to a data center’s overall availability or system redundancy, which may, or may not be totally accurate.
The terms “N, N+1 and 2N”, typically refer to the number of power and cooling components that comprise the entire data center infrastructure systems. Wherein “N” is the minimum rating of any component (such as a UPS, generator or cooling unit) required to support the critical load. An “N” system is not redundant at all, and the failure of any component will cause an outage, effectively describing a tier 1 type facility. N+1 and 2N, represent increasing levels of component redundancies and power paths, roughly mapping to the tiers 2-4, however it is important to understand that redundant components in themselves do not guarantee continuous availability, nor insure compliance with an Uptime Institute certified data center tier level.
Moreover, besides redundancy, the ability to do planned maintenance or emergency repairs on systems may involve the necessity to take them offline. This involves the key concept of “concurrent maintainability” which permits systems to be bypassed, without impacting the availability of the computing equipment. The Uptime Institute is well recognized in clearly defining concurrent maintainability in their Tier Level system. This is one of the key criteria in the design or certification of Tier III and Tier IV data centers.
Besides the level of infrastructure redundancy at the facility level, consistency of procedures for operations, maintenance and support of the critical infrastructure systems are key to ensuring continuous availability. Moreover, the Uptime Institute has now also established a related sub-category called Operational Sustainability to define and evaluate data center’s operational procedures, as an addition to their well recognized Tier Classification rating system.
Whether you chose to build or buy, you should examine all of these factors very closely to understand what is being promised if it is a brand new building and/or what the operating history of a proposed data center facility provider has been.

4 Ways to Extend the Life of UPS Batteries
Data center backup power is a crucial element to uptime and availability. During an outage, Uninterrupted Power Supply (UPS) enables the switch from utility power to backup generator power. But there is a relatively unreliable and expensive variable to most UPS: batteries.
Batteries represent three evils: They are big, they are expensive, and they are expendable. Anything you can do to prolong the life of your batteries will indeed extend the availability of your data center.
So here are four ways that data center facility managers can extend the life of their UPS batteries.
(1) Buy the right UPS battery for your data center
In a data center, UPS is designed to fully discharge the battery source within 20 minutes. This is called high-rate discharge. High-rate batteries have thinner plates and more plates than lower-rate batteries, but as a result high-rate batteries can lead to a shorter lifespan.
There are many other factors in buying UPS batteries, such as the life expectancy, voltage, front or top access, flag post or inserted post, and other considerations. For example, a small format valve regulated lead acid (VRLA) battery has a relatively low first cost but lower reliability. Meanwhile, a nickel cadmium (NiCd) battery has the best reliability and longest service life, but the first cost can be four times as much as other batteries.
Data center manager must also be aware of potential manufacturing problems such as faulty post seal design and internal connection problems.
(2) Install, operate and maintain batteries correctly
Incorrect installation can lead to shortened battery life, as can improper maintenance. Good maintenance means giving the batteries well ventilated air that is as close as possible to 77 degrees Fahrenheit, and making sure that all batteries in the string are getting air within 3 degrees Fahrenheit to ensure that some of the batteries don't age more quickly than others.
Why? Mixing batteries of different ages or internal resistances can prompt batteries to die more quickly. Regular inspections of the batteries can unveil problems such as loose intercell connections and damaged post seals, which can lead to corrosion and even fires.
Data center manager should also be aware of the battery's discharge status as well. A fully or nearly fully discharged battery that isn't recharged within 48 hours can lead to damage. Overdischarging a battery can cause recharge problems, and excessive discharging -- for example, if a data center does weekly testing of its backup systems that includes battery cycling -- can reduce battery life.
(3) Monitor the UPS batteries' capacity
When the internal resistance of a battery rises due to normal aging factors such as corrosion, and when it has increased by as little as 30%, it's time to replace them. This is most often measured through capacity testing, as most manufacturers say that when a battery drops to 80% of its original capacity, it's cooked!
Users should perform capacity testing on their batteries based on IEEE standards; in particular, IEEE 1188 or IEEE 450.
(4) Flywheel UPS in conjunction with battery UPS
When flywheel UPS is installed with battery UPS, the flywheels can often handle the shorter power outages that happen more often and can prevent the batteries from cycling. The flywheel UPS also helps to extend battery life by two years preliminary.
In addition, flywheel can filter out the 'dirty power, such as little power blips and spikes. The batteries would filter those spikes out but if you hit the batteries with those spikes, it will kill the battery life.

Data Center with Building Management System (BMS)
Most commercial buildings today integrate a number of different systems, ranging from power distribution to heating and cooling to physical security. Perhaps no facility is a better example than the data center which enables continuous operation of sensitive IT equipment and networks.
Keeping eyes on all the systems necessary for functioning a data center is virtually impossible unless you are using some form of management system.
Building Management System (BMS) with Data Center
Let's temporary ignore the networking and IT facilities, a typical data center must provide consistent, stable power, even in the event of a utility outage, as well as cooling, physical site security, lighting, fire suppression and other systems. Although many of these are common to a typical office building, their use in a data center requires added capabilities or special measures owing to the critical purposes. For instance, fire suppression should ideally enable extinguishing fires without destroying servers and other equipment.
Even with monitoring equipment in place, such as temperature and humidity sensors, power monitoring, various security measures and so on, it may be not practical to hire personnel to record the measurements or simply keep an eye on all these facilities. In this case, automation can be done through Building Management System (BMS).
A BMS handles the work of monitoring and recording data for various infrastructure systems. It also adjust the operation of these systems automatically to maximize the uptime and the operating efficiency. There are a few areas where building management systems can play an important role in the data center:
(1) Physical Security - A BMS can record who is entering secure areas of a facility via key cards or biometrics. Furthermore, it can implement various access-control measures, such as limiting access during certain times of the day or permitting certain personnel access to some areas but not others.
(2) Lighting Control - Servers may not need light to work, but people do. Unfortunately, owing to neglect or simply impracticality, lighting can become a major source of energy waste and thus decreased efficiency. A BMS can ensure that lights are shut off during off hours or when no motion is detected in a given area for some specified span of time.
(3) Efficient Cooling - As data centers move toward free cooling, air-side or water-side economizers and traditional mechanical cooling must function together in a manner that maximizes efficiency but still protects IT equipment. A BMS can balance these considerations. For instance, to run in economizer mode when the outside temperature is sufficiently low but to switch to CRAC units or water chillers when extra cooling is needed. If a hot spot develops, for instance, the BMS could increase air circulation at that point (if possible) or simply increase cooling to the appropriate area (or the entire facility).
(4) Power Distribution - Ensuring steady and clean power supply for the IT equipment is critical to keeping the data center running. A BMS monitors power conditions and provides alerts in the event of failure at some points in the power distribution system. In addition, the BMS can record data on power usage and conditions, enabling analysis for potential problems.
(5) Remote Monitoring Capability - When equipped with remote monitoring and alerts, the BMS can enable a facilities manager to keep an eye on conditions from another location—such as at home on a desktop computer or on the road via a laptop or tablet.
(6) Maintenance Scheduling - Data center maintenance is critical to keeping systems functioning. A BMS can indicate when infrastructure requires regularly scheduled maintenance, or when conditions merit preemptive maintenance to avoid a problem before it causes downtime. Automated maintenance reminders can prevent day-to-day tasks from causing employees and managers to forget periodic tasks that are necessary to the ongoing health of the facility.
(7) Enable Planning & Upgrades - The information that a BMS collects, in addition to providing a basis for maintenance and troubleshooting, can aid in planning for data center expansions or upgrades. For instance, power usage data relative to maximum capacity might indicate the need for greater capacity when additional IT equipment is installed.
(8) Improve Efficiency - Hardly the least concern of data center managers is increasing the efficiency of their facilities. Data collected by the BMS can be critical to determining which measures will increase efficiency and (potentially) by how much.
A building management system generally focuses on data center facilities. In some sense, a BMS could be considered a subset of the functions included in data center infrastructure management (DCIM). In the quest for greater integration and ultimate single-pane-of-glass monitoring and control of the data center, then, a BMS might be taken into account monitoring and controlling all aspects of the data center, including IT.
On the other hand, if you include IT functions in the scope of a BMS, then data center infrastructure management is simply a type of building management system specific to the needs of IT facilities.
Regardless of whether you differentiate DCIM from BMS, these systems illustrate the move of data centers toward greater integration of various systems and the centralized control and monitoring of the entire facility. A BMS enables data center managers to more promptly respond to problems as well as to identify, diagnose and address potential problems before they affect operations.

Data Center Power System Design
Engineers should take a closer look at the different power strategies being used to distribute power, and how they impact the data center.
Alternating Current (AC) versus Direct Current (DC) is a battle that has been going on for more than a century and continues today in the data center industry. Although AC power is the standard, based on its potential for eliminating conversion losses and improving efficiency, many believe that DC power is the future of data center distribution. Still others believe that the same level of efficiency can be achieved with AC by using more efficient equipment with higher voltage distribution.
Electrical systems usually waste energy in the form of losses due to inefficiencies in the electrical equipment and distribution system. On average, the electrical distribution system losses account for 12% of the total energy consumed by the data center. For a data center with 2000 kW of IT load (2700 kW total load), that equates to an annual cost of USD$280,000
Power System Design Tips
So please review these six key items when planning a data center power distribution system:
Similar to the mechanical systems, modifications can be made to the electrical system to make it more efficient and save energy. The key to a good mission critical facility design is not to degrade the reliability of the facility in the process.
Typical Electrical Distribution Systems
Typical legacy data center electrical distribution system is made up of five major components:
Power is supplied to the data center at medium voltage from a utility/generator power source. The power is stepped down from medium voltage to distribution voltage by a substation transformer. The power then goes through an Uninterrupted Power Supply (UPS) system that conditions the power and provides ride-through capability during an outage until the generator starts. The power is then stepped down to substation voltage by a Power Distribution Unit (PDU). The PDU supplies power to the IT power supply where it is rectified and stepped down DC power, which is the internal operating voltage of the IT equipment.
Utility / Generator --MV AC--> MV/LV Transformers --480V AC--> Switchgear --480V AC-->
UPS --480V AC--> PDU --208/120V AC--> IT Power Supply --12V DC--> Servers
Four components in the legacy electrical distribution system with the highest losses are:
One method for increasing efficiency is to replace those pieces of equipment with more efficient equipment. Today with ultra-high-efficient transformers that efficiency is above 99.5%. Conventional double conversion UPS systems range from 84% efficient at 25% load to 94% at 100% load. Using flywheel or passive standby UPS topology can increase that range to 94% efficient at 25% load and 99% at 100% load.
Another method for increasing efficiency is to eliminate partial loading of the data center. Eliminating partial loading reduces losses by allowing the equipment to operate at its peak operating efficiency. This can be performed by designing a power system that is modular, grows with the load, or by designing a power system that uses flexible tiers, and matches the reliability and redundancy to the different programs within the data center.
A third method is to eliminate the inefficient electrical equipment altogether. Increasing efficiency by eliminating the equipment that has the most losses is the reason why different power strategies are being investigated for data center distribution.

Alternating Current (AC) versus Direct Current (DC) is a battle that has been going on for more than a century and continues today in the data center industry. Although AC power is the standard, based on its potential for eliminating conversion losses and improving efficiency, many believe that DC power is the future of data center distribution. Still others believe that the same level of efficiency can be achieved with AC by using more efficient equipment with higher voltage distribution.
Electrical systems usually waste energy in the form of losses due to inefficiencies in the electrical equipment and distribution system. On average, the electrical distribution system losses account for 12% of the total energy consumed by the data center. For a data center with 2000 kW of IT load (2700 kW total load), that equates to an annual cost of USD$280,000
Power System Design Tips
So please review these six key items when planning a data center power distribution system:
- Install or replace existing power and IT equipment with energy-efficient equipment
- Review the proposed IT equipment to determine if the systems can operate on 240 V AC or 380 V DC
- Review all the advantages and challenges of the different power systems
- Determine how much of the existing infrastructure would need to be replaced to change power systems
- Design flexibility into the power system that will allow the data center to adapt in the future
- Design a power system that is modular to eliminate partial loading
Similar to the mechanical systems, modifications can be made to the electrical system to make it more efficient and save energy. The key to a good mission critical facility design is not to degrade the reliability of the facility in the process.
Typical Electrical Distribution Systems
Typical legacy data center electrical distribution system is made up of five major components:
Power is supplied to the data center at medium voltage from a utility/generator power source. The power is stepped down from medium voltage to distribution voltage by a substation transformer. The power then goes through an Uninterrupted Power Supply (UPS) system that conditions the power and provides ride-through capability during an outage until the generator starts. The power is then stepped down to substation voltage by a Power Distribution Unit (PDU). The PDU supplies power to the IT power supply where it is rectified and stepped down DC power, which is the internal operating voltage of the IT equipment.
Utility / Generator --MV AC--> MV/LV Transformers --480V AC--> Switchgear --480V AC-->
UPS --480V AC--> PDU --208/120V AC--> IT Power Supply --12V DC--> Servers
Four components in the legacy electrical distribution system with the highest losses are:
- Substation transformer: Transformer no-load and core losses
- UPS: Rectifier and inverter losses
- PDU transformer: Transformer no-load and core losses
- IT power supply: Rectifier and transformer losses
One method for increasing efficiency is to replace those pieces of equipment with more efficient equipment. Today with ultra-high-efficient transformers that efficiency is above 99.5%. Conventional double conversion UPS systems range from 84% efficient at 25% load to 94% at 100% load. Using flywheel or passive standby UPS topology can increase that range to 94% efficient at 25% load and 99% at 100% load.
Another method for increasing efficiency is to eliminate partial loading of the data center. Eliminating partial loading reduces losses by allowing the equipment to operate at its peak operating efficiency. This can be performed by designing a power system that is modular, grows with the load, or by designing a power system that uses flexible tiers, and matches the reliability and redundancy to the different programs within the data center.
A third method is to eliminate the inefficient electrical equipment altogether. Increasing efficiency by eliminating the equipment that has the most losses is the reason why different power strategies are being investigated for data center distribution.
