The need for accurate air conditioning:
For areas such as telecommunications, information technology, banking, insurance, protecting expensive equipment in the data center, such as PBX, servers, switches operate in stable condition continuous operation 24 is very important. These devices need to be operating in an environment of open and regular cooling. If the operating environment does not guarantee, PBX, servers, switches may operate incorrectly, reboot, or damaged. Data center is the lifeblood of every company, if problems occur, the repair and replacement costs as well as the cost of losses due to disruption of all business activities of the company will be very high.
So, the data center cooling must always be timely, ensure the device is operating in an ideal environmental conditions. The conventional air conditioners can not provide an ideal operating conditions. Therefore, the accurate air conditioning should be used in this case to not only achieve high efficiency and reliability, but also saves energy.
Application:
- Continuous operation 24/7/365:
The conventional cooling system only operates during normal working hours ie only 8-12 hours a day. However, the telecommunications equipment and information technology in a data center usually operate 24 hours per day, 365 days a year. Meanwhile, they generate a huge amount of heat and requires cooling regularly to be able to operate correctly and reliably. The usual air conditioner will quickly lose the initial performance and will be damaged if continuous operation. The precision air conditioners are designed to run continuously so they are very durable and also ensure the original performance less decline over time.
- Operating temperature:
The conventional air conditioning system cooling can not be very high amount of heat generated in the data center, especially centers that use high-performance servers. These centers can generate a large amount of heat is 6-10 times the heat of a normal office. The use of accurate air conditioning will help maintain the temperature always at 220C ± 0.50C. Moreover, accurate air conditioning can react quickly to the changes in heat load to prevent the abnormal changes of temperature.
- Operating humidity:
Maintaining proper humidity in the data center is equally important as maintaining proper temperature to ensure the stable operation of equipment. If the humidity is too high, the water vapor in the air can condense and cause corrosion inside the device and cause a short circuit. If the humidity is too low, the accumulation of static electricity to a large enough intensity can cause damage to your equipment. Accurate air conditioners have the ability to control the humidity at 50 ± 2% RH.
- Air Flow Controlling
In a data center, beside the temperature factor, the flow of air circulation in the room is very important. Especially for the center using high-performance server with high density, air flow required will be greater than several times to ensure complete cooling air flow will blow to the server. While a normal office requires only two air changes per hour, data centers need to 30 air changes per hour with the air flow of 4000 - 5000 m3/hr. If you do not provide enough air flow accordingly, will generate the data center hot spots and abnormal changes of temperature cause damage or shorten the life of equipment.
- Air Filter:
Accurate air conditioner has the ability to clean the air filter at a very high level. For dust grains with sizes in the 0.3 - 5 micron filter capabilities of up to 99,999%.
- Cooling with high performance
During the cooling process, the conventional air conditioner will cool the air (RMS - sensible cooling capacity) and air dehumidification (power consumption - latent cooling capacity). The accurate air conditioners are mainly air cooling and humidity control at the appropriate level should be the same theoretical capacity (RMS public consumption), accurate cooling will likely higher than normal. While conventional air conditioners can use 50% of the energy for cooling and 50% of the energy for dehumidification, air conditioner correctly only about 5% of the energy use in order to remove moisture and the remaining 95% to cool air, thus cooling performance of the air conditioner correctly is much higher
