In modern society, the application of refrigeration equipment is becoming more and more extensive. Modern refrigeration devices are used to cool the cold water machine, and the market development prospect of the cold water machine can be extended.
Refrigerating set
The chiller consists of four main components: compressor, evaporator, condenser and expansion valve, thus achieving the cooling and heating effect of the unit. the unit by using the theory of heat exchange by heat exchanger to lower the temperature of cooling water to the required temperature (5 ℃ or higher, low temperature - 20 ℃ or higher), water heat exchange through the frozen water pump into the evaporation tank, produce chilled water, water pump suction cycle into the evaporator water tank. When chilled water is insufficient, frozen water cannot promote the water flow switch blade, refrigerating machine stopped running, the automatic filling water device then began to work for filling water, can be judged through the liquid level display tank water level, open chiller again.
considerations:
1、When the machine is shut down, the chiller should be closed half an hour before the work, and the cold water pump will be closed after work, which will save energy and prevent the failure of the shutdown and protection of the unit.
2、Before running the refrigeration cycle, it should be confirmed that the valve of the heat cycle pipe has been closed.
