Glycol chiller is an industrial chiller with glycol as refrigerant. The structure of glycol chiller is roughly the same as that of ordinary industrial chiller, which is composed of compressor, evaporator, condenser and electric control system. In order to ensure the stable operation of glycol chiller, we suggest that you take explosion-proof measures and buy explosion-proof glycol chiller as far as possible.
1、 Operation of compressor
In order to ensure that the pressure inside the evaporator is low enough and that the refrigerant is at such a low temperature, the compressor is used to extract the evaporated refrigerant and compress the low temperature and low pressure into high temperature and high pressure refrigerant gas.
2、 Use of condenser
High temperature and high pressure refrigerant condenses into liquid in the condenser. The refrigerant in the condenser releases heat in air or water lower than its temperature. Of course, the temperature of air or water must be lower than that of refrigerant.
3、 How to throttle
After passing through the restrictor, the refrigerant of the chiller drops from the condensation pressure to the evaporation pressure, so the liquid from the condenser can be placed in the liquid reservoir. At this time, the refrigerant is in the state of normal temperature and high pressure, and then passes through the expansion valve to reduce the boiling point, enters the evaporator, and the liquid absorbs heat and evaporates.
4、 Endothermic evaporation
After passing through the restrictor, the refrigerant liquid with low temperature and low pressure exchanges with the evaporator, and the absorbed heat becomes saturated or superheated steam.
