Air cooled chiller is one of the models of chillers, which cools water at room temperature to a certain temperature through the compressor of the chiller to enhance the cooling of molds or machines. It is used as a standalone unit, with a built-in fan as the heat dissipation device. There are mainly three interconnected systems: refrigerant circulation system, water circulation system, and electrical self-control system.

Refrigerant circulation system:
The liquid refrigerant in the evaporator absorbs heat from the water and begins to evaporate, eventually forming a certain temperature difference between the refrigerant and water. The liquid refrigerant also completely evaporates into a gaseous state, which is then sucked in and compressed by the compressor (increasing pressure and temperature). The gaseous refrigerant releases heat through the condenser and condenses into a liquid. After being throttled by an expansion valve (or capillary tube), it becomes a low-temperature and low-pressure refrigerant that enters the evaporator, completing the refrigerant circulation process.
Water circulation system:
The water pump is responsible for extracting water from the water tank and pumping it to the equipment that the user needs to cool. The chilled water takes away the heat and rises in temperature before returning to the chilled water tank.
Electrical self-control system:
Including power supply and automatic control parts.
The power supply is supplied to compressors, fans, water pumps, etc. through contactors.
The automatic control part includes a temperature controller, pressure protection, delay device, relay, overload protection, etc., which are combined to achieve functions such as automatic start stop and protection based on water temperature.
