What is Data Center Cooling? Data centers require a cool environment for the processor to function successfully, because excess heat can damage the systems and result in data loss or interrupted information flow. In data centers, cooling systems are used to prevent such damage and preserve the air temperature within acceptable limits. Data center cooling solution is used to maintain ideal environmental conditions for information technology equipment (ITE) operation. The technology eliminates ITE heat and transfers it to the heat sink. Thus, it can be inferred that data centers cannot function efficiently and can result in a system failure in the absence of an appropriate cooling system. Why do data centers need cooling? One of the most important and less understanding processes in the critical IT environment is data center heat removal. As the latest computer equipment is smaller and uses the same or more electricity than the replaced equipment, more heat is generated in data centers. Precision cooling and heat rejection systems are used for collecting and transporting this undesired heat energy into the outer atmosphere. 1. Increasing need for energy-efficient data center facilities The energy consumption in the ICT sector has increased exponentially in recent years. The data centers, recently experiencing unprecedented growth in size and population, form an integral part of today’s ICT. The Tech giants such as Google, IBM and Microsoft have large cloud and app hosting data centers. Several studies have been established for energy consumption of data centers, these studies emphasize upon the rising need for evolving strategies for energy efficiency. Heat generated from highly populated data centers requires huge cooling units to maintain the temperatures within the operational range. 2. Rising shift toward digital transformation through connected technology Lately, digital transformation has gathered a lot of attention. It not only includes deployment of new technologies, but also the alteration of business processes and models that can completely leverage such technologies. It helps organizations to obtain unmatched productivity levels, improve customer experience, influence innovation and enlighten competitive benefits. Digital transformation is altering the nature of the data center, and novel technologies are rapidly placing more demand on data centers and data center services. Types of Solutions · Air Conditioners In basic terms, air conditioning involves removing heat and humidity from the inside of an occupied area to improve the occupants comfort. In both domestic and commercial environments, air conditioning can be used. This process ensures a more comfortable interior environment for humans, however air conditioning is also used to cool/dehumidify roommates filled with electronic heat-producing devices such as computer servers, power amplifiers, and some sensitive products, like artifacts, even for display and storage. · Precision Air Conditioners Precision air conditioning is designed to manage sensitive heat (humidity without the emanation of a machine), while latent heat (humidity with the emanation of persons) is managed with comfort/standard air conditioners. Designed for many different applications, high-precision air conditioning including cooling of the data center, medium and low-density server environments, telecom switching systems, medical operating theaters, and a clean-room environment is essential. · Chillers Data centers constitute a mix of computing elements, networking infrastructure, storage systems along with power management and cooling capabilities all of which offer opportunities for improving energy efficiency and achieving more sustainable data centers. With air-cooled chillers, heat is removed from the returning chilled water is rejected to a device called an air-cooled condenser that is typically integrated with the chiller. This type of chiller is known as a packaged chiller and can also be integrated into a cooling facility module.

Staff in data centers or computer rooms will encounter unexpected situations where precision air conditioners are not cooling. Through this article, we will briefly analyze the reasons why the precision air conditioner in the computer room does not cool. First, too little refrigerant or slight qualitative change. 1. Leakage occurs in the refrigeration pipeline and its components and the interfaces between them after long-term work. 2. The refrigerant flows in the pipeline, and there will definitely be a small amount of loss after the air conditioner works for a long time; with the passage of time, the refrigerant will also undergo slight qualitative changes. Second, the air filter is dirty. 1. The air filter should be replaced regularly according to the climate and environmental conditions of the region. If the air filter is too dirty, the return air will be blocked, and the heat exchange of the evaporator will not work properly. 2. In order to save costs, some companies clean the air filter with water. This operation will cause the filter to change from filament to sheet, and the return air resistance will increase. It will also make the air filter mesh larger, and the filtering effect is poor. A lot of dust will be directly adsorbed on the evaporator fins through the filter, which will seriously affect the working effect of the evaporator. Third, the pipeline insulation layer is damaged or the pipeline is too long. 1. The damage of the insulation layer of the pipeline makes the refrigeration pipeline directly contact with the air, and the heat exchange occurs on the pipeline in advance. 2. Too long pipeline will reduce the cooling effect. Fourth, the compressor problem. The compressor directly affects the cooling capacity, and the degree of damage to the compressor has different effects on the cooling capacity. Fifth, other reasons. 1. The condenser and evaporator are not clean. 2. The expansion valve fails. 3. The filter fails. 4. Refrigerant quality change. 5. The indoor fan speed is not enough. 6. There are too many heating equipment in the room, and the sealing of the machine room is not strict. 7. The quality of the precision air conditioner is unqualified. 8. Obstruction of the air supply duct. 9. The refrigeration pipeline is too dirty and blocked.
