coldwater machineBasic components of refrigeration system:

coldcondenserDuring the refrigeration process, the condenser plays a role in outputting heat energy and allowing the refrigerant to condense. After the high-pressure superheated vapor discharged from the refrigeration compressor enters the condenser, all the heat absorbed during its operation, including the heat absorbed from the evaporator, refrigeration compressor, and pipeline, is transferred to the surrounding medium (water or air) for removal; The high-pressure superheated vapor of the refrigerant condenses back into liquid. According to the different cooling media and cooling methods, condensers can be divided into three categories: water-cooled condensers, air-cooled condensers, and evaporative condensers

Liquid storageimplementThe liquid storage container is installed after the condenser and is directly connected to the condenser's discharge pipe. The refrigerant liquid in the condenser should flow smoothly into the accumulator, so as to fully utilize the cooling area of the condenser. On the other hand, when the heat load of the evaporator changes, the required amount of refrigerant liquid also changes accordingly, and at that time, the accumulator plays a role in regulating and storing the refrigerant. For small chiller refrigeration systems, a liquid storage device is often not installed, but a condenser is used to regulate and store refrigerant.

Dried outfilterIn the refrigeration cycle of a chiller, it is necessary to prevent the entry of moisture and dirt (oil stains, iron filings, copper filings). The main sources of moisture are trace amounts of moisture contained in newly added refrigerants and lubricating oils, or moisture caused by the entry of air during system maintenance. If the moisture in the system is not completely removed, when the refrigerant passes through the throttle valve (thermal expansion valve or capillary tube), the moisture may solidify into ice due to the decrease in pressure and temperature, causing channel blockage and affecting the normal operation of the refrigeration device. Therefore, a dry filter must be installed in the refrigeration system of the chiller.

evaporationimplementEvaporator is a heat exchange device that relies on the evaporation (actually boiling) of refrigerant liquid to absorb heat from the cooled medium. Its function in the refrigeration system is to absorb heat (or output cooling capacity). In order to ensure the stable and long-lasting evaporation process, it is necessary to continuously use a refrigeration compressor to extract the evaporated gas and maintain a certain evaporation pressure.

Thermal expansionExpansion valveThe thermal expansion valve is both a flow regulating valve and a throttle valve in the refrigeration system of a chiller. It is installed between the drying filter and the evaporator in the refrigeration equipment, and its temperature sensing package is wrapped around the outlet of the evaporator. Its main function is to reduce the flow and pressure of high-pressure and room temperature refrigerant liquid when it flows through the thermal expansion valve, turning it into low-temperature and low-pressure refrigerant wet vapor (mostly liquid, a small part steam) that enters the evaporator, vaporizes and absorbs heat inside the evaporator, and achieves the purpose of refrigeration and cooling.

Refrigerant: Most industrial chillers used in modern industry use R22 or R12 as refrigerants. Refrigerant is the flowing working fluid in refrigeration systems, whose main function is to carry heat and achieve heat absorption and release when the state changes.

Air cooled chillers are mainly used to cool the heating components of equipment, ensuring that the equipment operates normally at a constant temperature. The air-cooled chiller is suitable for high-speed spindles, electric spindles, CNC machine tools, coordinate boring machinesrubbedProcessing centers, laser marking machines, laser engraving machines, laser welding machines, laser coding machines, laser cutting machines and other equipment.
