  Industrial chiller unit configuration: equipped with a single-chip control system, built-in compressor drier filter and expansion valve, maintenance hand valve interface and other devices, to ensure the reliable and safe operation of the machine to facilitate maintenance and repair.

  1. Compression: The refrigeration method of industrial chillers is to compress the refrigerant (refrigerant) into high temperature and high pressure vapor through the compressor and discharge it into the condenser;

  2. Condensation: When the pressure remains unchanged, it is cooled by the cooling medium (water or air), releases heat, reduces the temperature, and further condenses into liquid, which is removed from the condenser;

  3. Throttle: When the high-pressure refrigerant liquid passes through the throttle valve, the pressure drops due to obstruction, which causes part of the refrigerant liquid to vaporize, absorb the latent heat of vaporization, and reduce its temperature accordingly, and become wet vapor at low temperature and low pressure. Enter the evaporator;

  4. Evaporation: In the evaporator, the refrigerant absorbs the heat of the cooled medium (air, water or salt water, etc.) under the condition that the pressure remains unchanged, and vaporizes, forming low-temperature and low-pressure vapor and then compressed The machine sucks away, so the cycle compresses and cools;

  5. Refrigeration: The evaporator is cooled by the medium (air, water or salt water, etc.) and then the low-temperature chilled water or brine is sent to the equipment that needs cooling by the water pump. The chilled water heat is taken away and the temperature rises and then flows back into the chiller In the evaporation system, a cooling cycle is formed to achieve the purpose of refrigeration.
