Product Introduction                                     

Computer room air conditioner refers to a special precision air conditioner (also called constant temperature and humidity air conditioner) that can fully meet the environmental conditions of the computer room. It is a new model that has been gradually developed in the past 30 years. When comfortable air conditioners were used in early computer rooms, problems such as unstable operation of equipment in the computer room, interference with data transmission, and static electricity were often encountered due to improper control of ambient temperature and humidity parameters. The use of precision air conditioners can stabilize the indoor environment, ensure the smooth operation of equipment, improve equipment utilization efficiency, and save enterprise operating costs.

Benefits                                     

Expansion Valve

• Fast response speed to achieve precise cooling;

Scroll 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;
• Greatly reduce compressor start and stop times and improve system reliability;
• Brushless DC maintenance-free motor, easy to operate and maintain;
• Soft start function to reduce the impact on the power distribution system;

Indoor Blower 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;

1. Cooling capacity measurement conditions: inlet air dry bulb temperature 23°C, wet bulb temperature 17°C; condenser inlet air dry bulb temperature 35°C, wet bulb temperature 24°C.
