How small air cooled chiller works?

The small air cooled chiller sucks the low-temperature and low-pressure refrigerant gas after evaporation and refrigeration from the compressor, and then compresses it into high-temperature and high-pressure gas and sends it to the condenser. After the high-pressure and high-temperature gas is cooled by the condenser, the gas condenses into a normal temperature and high pressure liquid. When the normal temperature and high pressure liquid is It flows into the thermal expansion valve, is throttled into low-temperature and low-pressure wet vapor, and flows into the shell-and-tube evaporator. It absorbs the heat of the frozen water in the evaporator to lower the water temperature. The evaporated refrigerant is then sucked back into the compressor and repeated Next refrigeration cycle, thereby achieving refrigeration purposes.

The small air cooled chiller is one of the chiller models. It cools the normal temperature water to a certain temperature through the compressor of the chiller to strengthen the cooling of the mold or machine. It is used as a stand-alone machine. The heat dissipation device is a built-in fan. There are three main interconnections. Systems: refrigerant circulation system, water circulation system, electrical automatic control system.

Refrigerant circulation system

The liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate. Eventually, a certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant also completely evaporates into a gaseous state, and is then sucked and compressed by the compressor (pressure and temperature increases), the gaseous refrigerant releases heat through the condenser and condenses into a liquid. After being throttled by the expansion valve (or capillary tube), it becomes low-temperature and low-pressure refrigerant and enters the evaporator to complete the refrigerant cycle process.

water circulatory system

The water pump is responsible for pumping water from the water tank to the equipment that the user needs to cool. The chilled water takes away the heat and the temperature rises, and then returns to the chilled water tank.

Electrical automatic control system

Including power supply part and automatic control part.

The power supply part supplies power to compressors, fans, water pumps, etc. through contactors.

The automatic control part includes a thermostat, pressure protection, delayer, relay, overload protection, etc. that are combined to achieve automatic start-stop, protection and other functions according to the water temperature.
