The 8 accessory usages that must be mastered when using computer room air conditioners!

The electrical control and air circulation of the computer room air conditioner are independent units. During maintenance and overhaul, the air conditioner does not need to be turned off, and the stable air flow and temperature gradient in the air conditioner room can also be ensured.

1. Indicator

　　The liquid moisture indicator of the sight glass provides an accurate way for the user to confirm the quality and moisture content of the refrigerant in the system.

　　2, switch

　　The pressure switch is used to protect the refrigeration compressor in the air conditioning system to prevent the compressor's suction pressure from being too low or the discharge pressure from being too high. In addition, the pressure switch is also used to start and stop the condenser fan.

　　3, expansion valve

　　The thermal expansion valve is usually installed between the liquid storage cylinder and the evaporator, which can make the high temperature and high pressure liquid refrigerant become low pressure wet vapor through throttling, and then the refrigerant absorbs heat in the evaporator to achieve the cooling effect.

　　4, refrigerant

　　 In refrigeration and air conditioning systems, a working fluid used to transfer heat energy to produce a freezing effect. The refrigerant liquefies to release heat and vaporizes to absorb heat. If the evaporator and condenser are installed in different positions, the machine will move the heat to different positions.

　　 5. Monitoring

　　Pan-geographic precision air-conditioning computer room monitoring system is composed of three parts: front-end equipment, client/server APP, and PC large screen. Users can check the operating status and related parameters of precision air-conditioning in real time after logging in through the client APP/PC. When there are failures such as temperature and humidity return air, air supply limit, etc., the alarm information can be received synchronously, and the fault can be solved quickly.

　　6, pre-filter

　　 The pre-filtration of the ventilation system of the computer room air conditioner, the return air filtration of the clean air-conditioning clean room, the pre-filtration of high-efficiency filtration, and the pre-filtration of air compressors.

　　7, solenoid valve

　　Direct-acting solenoid valves can operate normally under vacuum, negative pressure or zero pressure, and are used in refrigeration, pneumatic, water supply, steam and hydraulic systems. The solenoid valve uses a fully plastic solenoid coil and DIN international standard electrical connection equipment, with good insulation, waterproof, moisture-proof, shock-resistant and corrosion-resistant capabilities.

8. Dry filter

　　The liquid pipe uses a filter drier to protect the refrigeration series from contamination by liquid and solid pollutants. It is equipped with a specially formulated desiccant mixture, which can remove acid and moisture in any refrigeration system.

　　 The computer room air conditioner is one of the important prerequisites to ensure the normal operation of the computer system. The computer room air conditioner adjusts the temperature, humidity and cleanliness of the computer room to create a good operating environment for computer equipment.
