Introduction of air cooled liquid chiller:

The air cooled liquid chiller is a cooling water equipment that can provide constant temperature, constant flow and constant pressure. It consists of three major components: refrigeration system, water system, and electrical system. The core is the refrigeration system. The refrigeration system is a refrigeration equipment composed of a compressor, evaporator, condenser, and expansion valve. Because its condenser (radiator) is of fin type and the chiller dissipates heat from the environment through one or more external rotor fans, it is called an air-cooled chiller.

The core advantages of the air-cooled type: it comes with a refrigeration system, water pump, water tank, and control system. After arriving at the customer site, the customer can install it by himself and use it in areas where water sources are scarce and cooling water sources are inconvenient.

Air-cooled chiller refrigeration cycle principle diagram:

The core components of air cooled liquid chiller consist of:

1. Compressor

The compressor is the core component of the entire refrigeration system and the source of power for refrigerant compression. Its function is to convert the input electrical energy into mechanical energy and compress the refrigerant.

2. Condenser

During the refrigeration process, the condenser plays the role of outputting heat energy and condensing the refrigerant. After the high-pressure superheated steam discharged from the refrigeration compressor enters the condenser, all the heat absorbed during the working process, including the heat absorbed from the evaporator and refrigeration compressor and in the pipeline, is transferred to the surrounding medium (water or Air) is taken away; the high-pressure superheated vapor of the refrigerant condenses back into liquid. According to different cooling media and cooling methods, condensers can be divided into three categories: water-cooled condensers, air-cooled condensers, and evaporative condensers.

3. Evaporator

The evaporator is a heat exchange device that relies on the evaporation of refrigerant liquid to absorb the heat of the cooled medium. Its function in the refrigeration system is to absorb heat (or output cooling capacity). In order to ensure that the evaporation process can proceed stably and lastingly, the evaporated gas must be continuously pumped away by a refrigeration compressor to maintain a certain evaporation pressure.

Refrigerant: Most industrial chillers used in modern industry use R22 or R12 as the refrigerant. Refrigerant is the flowing working fluid in the refrigeration system. Its main function is to carry heat and absorb and release heat when its state changes.

4. Expansion valve

The expansion valve is not only a flow regulating valve in the chiller refrigeration system, but also a throttle valve in the refrigeration equipment. It is installed between the drying filter and the evaporator in the refrigeration equipment. Its temperature sensing bag is wrapped around the evaporator. ‘s exit. Its main function is to throttle and reduce the pressure of high-pressure and normal-temperature refrigerant liquid when flowing through the thermal expansion valve, and turn it into low-temperature and low-pressure refrigerant wet vapor to enter the evaporator, vaporize and absorb heat in the evaporator, and achieve the purpose of cooling and cooling.
