70 - 80Kw Coolnet Precision Air Conditioning Units For Mobile Stations

Product Introduction                                              

Coolnet precision air conditioner can control the temperature difference range to 0.1 degrees Celsius or even higher. Similarly, this series of precision air conditioners can use a larger circulating air volume to reduce the enthalpy difference under a certain cooling capacity, so usually the unit can only operate under a relatively high sensible heat ratio. This is precisely suitable for server rooms and data centers which are placed in plenty of equipment with high demand in heat dissipation.

Benefits                                      

DC inverter compressor
Using R410A environmentally friendly refrigerant, DC frequency conversion, high efficiency and energy saving;
Dynamic cooling to adapt to the rapidly changing heat load of the computer room;
Save energy at low loads, improve energy efficiency, and reduce Opex throughout the life cycle;
 

EC fan
The use of electronically commutated synchronous EC electrodes can save energy by 20% to 30%;
Automatically adjust the fan speed according to cooling demand or wind pressure, and provide air volume on demand;
Soft start function, low starting current;
The impeller is made of aviation-grade engineering composite material, which is light in weight, efficient and reliable;

Dual electronic expansion valve
Smoothly adjust the throttle opening, and cooperate with the DC inverter compressor to achieve energy saving;
Wide adjustment range, reduce superheat and improve energy efficiency ratio;

Advantages                                   

• A variety of cooling methods, including air cooling, water cooling, etc., are conducive to adapting to the actual conditions of the site
• Standard RS485 communication interface, ModBus communication protocol
• Multiple monitoring methods
• Air-cooled condensers are available in configurations suitable for different temperature environments, including low temperature start-up
• The air-cooling method provides a solution with ultra-long installation distance and ultra-high drop

1) Large air volume and small enthalpy difference. The higher the sensible heat ratio of the same heat load, the greater the required air supply volume. This requires that the air conditioning system of the computer room can provide a larger air supply volume.

2) The heat load of the machine room changes greatly. The precise air conditioning system of the computer room must be able to adapt to the change of this load, so that the electronic components can work in the required environmental conditions and ensure the reliability of the circuit function.

3) Reliability. Alarm, automatically use the backup unit or backup control unit to switch the faulty unit or faulty unit. The control system function of the special air conditioner for the computer room is much better than that of the comfort air conditioner.
