  Air-cooled chillers , as relatively efficient refrigeration equipment in chiller products, are widely used in the domestic industrial market and become necessary equipment for many industrial productions. At the same time, although the air-cooled chiller is equipped with multiple protection devices, these are all to prevent failures from directly damaging the unit. If the company wants to ensure that the air-cooled chiller has high cooling efficiency and long service life, it must remember to do regular maintenance. So, how should the normal safety maintenance and inspection of air-cooled chillers be carried out? 1.Check the stability of voltage and current When the air-cooled chiller works normally, the voltage is 380V (the voltage of DYJ-01A～DYJ-02A is 220V, and the voltage of other regions abroad also has 410V, etc.), and the current is normal within the range of 11A-15A; 2. Regularly check the compressor The compressor is the "heart" of the chiller, and its quality dire

  The   chiller   is the refrigeration source and "heart" of the central air conditioner. The circulating water to each room is "internally exchanged" by the chiller, and the temperature is reduced to "cooling water". It consists of a refrigerator, cooling water circulation system, chilled water circulation system, fan coil system, and cooling tower. The working principle of the chiller The refrigerator compresses the refrigerant into a liquid state through the compressor, and then sends it to the evaporator for heat exchange with chilled water. The chilled water is refrigerated. The chiller pump sends the chilled water to the cooling coils of the air outlets of each fan. purpose. The evaporated refrigerant releases heat in the condenser into a gaseous state, the cooling pump sends the cooling water to the cooling tower, and the water tower fan sprays and cools it, exchanges heat with the atmosphere and radiates the heat to the atmosphere go with.
