Air Cooled Chillers For Sale

Features of air cooled chillers:

1. The compressor adopts a scroll type hermetic compressor and electric control components, and is equipped with a condenser and an evaporator made of high-quality copper tubes with high heat exchange efficiency;

2. Equipped with various safety protection devices, with stable performance, low noise, long service life and simple operation; LCD human-machine interface is adopted, which is simple and convenient to operate, and the operating status is clear at a glance;

3. Air cooled chillers adopt single compressor or multi-compressor combined refrigeration system. The compressors can automatically run alternately according to load changes, balancing the running hours of each compressor, achieving the effect of saving energy and extending the service life of the chiller. Facilitate energy regulation, more energy saving at partial load;

4. Air cooled chillers adopt shell box structure, beautiful appearance and compact structure, and can check the operation of the unit at any time; the unit can have its own water tank and circulating water pump according to the cooling capacity, without cooling tower and cooling water pump, easy to install and maintain ;

The basic composition of the refrigeration system of air cooled chillers:

Condenser: In 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, it transfers all the heat absorbed in the working process, including the heat absorbed from the evaporator and refrigeration compressor and in the pipeline, to the surrounding medium (water or air) away; refrigerant high-pressure superheated vapor recondenses 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.)

Liquid reservoir: The liquid reservoir is installed after the condenser and is directly connected to the drain pipe of the condenser. The refrigerant liquid in the condenser should flow into the liquid receiver unimpeded, so that the cooling area of the condenser can be fully utilized. On the other hand, when the heat load of the evaporator changes, the demand for refrigerant liquid also changes accordingly, and at that time, the liquid receiver plays the role of adjusting and storing the refrigerant. For the small chiller refrigeration system, the liquid receiver is often not installed, but the condenser is used to adjust and store the refrigerant.

Drying filter: In the refrigeration cycle of the chiller, moisture and dirt (oil, iron filings, copper filings) must be prevented from entering. The source of moisture is mainly the trace moisture contained in the newly added refrigerant and lubricating oil, or due to Moisture from air ingress during system servicing. If the moisture in the system is not removed, when the refrigerant passes through the throttling valve (thermal expansion valve or capillary tube), the moisture will sometimes freeze into ice due to the drop in pressure and temperature, blocking the passage and affecting the normal operation of the refrigeration device. Therefore, a dry filter must be installed in the chiller refrigeration system.

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

Thermal expansion valve: The thermal 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 dry filter and the evaporator in the refrigeration equipment. Its temperature sensor It is wrapped around the outlet of the evaporator. Its main function is to make the high-pressure and normal-temperature refrigerant liquid throttling and reducing pressure when it flows through the thermal expansion valve, turning into low-temperature and low-pressure refrigerant wet vapor (mostly liquid, a small part is steam) into the evaporator, and vaporized in the evaporator absorb heat, and achieve the purpose of cooling and cooling.
