Three circulation systems of industrial chillers

Three circulation systems of industrial chillers

Water chillers play a very important role in the industry. They are needed in the refrigeration process of electroplating, chemical, printing, pharmaceuticals, plastics and other industries. Due to the wide range of applications of chillers, let’s understand Let's look at the three major circulation systems of the chiller.

　　 Water chillers are not only used in the fields of plastics and electronic cooling, but also in medical equipment, leather processing, etc., and air conditioning and refrigeration in people's daily public activities will also be applied to chillers. The chiller operates through three systems interconnected: refrigerant circulation system, water circulation system and electrical automatic control system.

　　 1. Refrigerant circulation system

There is a liquid refrigerant in the evaporator of an industrial chiller. The refrigerant begins to evaporate after absorbing the heat in the water. After z*, there will be a temperature difference between the water and the refrigerant, and the liquid cooler is completely evaporating Later, it will become gaseous, absorbed by the compressor, and then compressed. The gaseous refrigerant passes through the condenser to dissipate heat, the temperature drops and then condenses into liquid, z* finally completes the process of the refrigeration cycle.

　　2, water circulation system

　　The function of the water pump is mainly to pump water from the water tank to the equipment that needs to be cooled. The water will heat up after the heat is replaced, and then return to the frozen water tank.

　　3, electrical automatic control system

　　 includes the automatic control part and power supply part of the industrial chiller system. The automatic control part includes relays, pressure protection, thermostat, pressure protection, thermostat, delay, overload protection, etc. The combination can automatically adjust the start or stop according to the water temperature. After the power supply passes through the contactor, it mainly supplies power to the compressor, water pump and fan lights.
