Contact us today for the perfect temperature control solution

70 ton water chiller is a cooling equipment system that integrates refrigeration, cooling, and water supply. It is mainly used to provide cooling water or cooling liquid to meet the cooling needs of industry, commerce, and living areas.

How does the 70 ton water chiller work?

70 ton water chiller achieves cooling effect through refrigeration cycle system. It consists of major components such as compressor, condenser, evaporator and control system. The refrigerant absorbs heat during circulation and releases the heat into cooling water or cooling liquid, thereby achieving a cooling effect.

70 ton water chiller basic components of refrigeration system

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, 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.)

Liquid receiver: The liquid receiver is installed after the condenser and is directly connected to the drain pipe of the condenser. The refrigerant liquid of the condenser should flow into the liquid receiver unobstructed, 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. At this time, the liquid receiver plays the role of adjusting and storing refrigerant. For small chiller refrigeration equipment systems, liquid receivers are often not installed, but condensers are used to adjust and store refrigerant.

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

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 (output cold energy). 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.

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 drying filter and the evaporator in the refrigeration equipment. Its temperature sensing package It is wrapped at the outlet of the evaporator. 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 (mostly liquid, a small part is steam) into the evaporator, and vaporizes in the evaporator. Absorb heat to achieve cooling and cooling purposes.

Refrigerant: Most industrial chillers used in modern industry use R22 or R12 as 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.
