An application in all walks of life a kind of auxiliary water cooling equipment, constant temperature, constant current, constant refrigeration equipment named East Star water-cooled screw chillers. At the same time, it is also a kind of energy saving and environmental protection equipment. Principle is: first to the device in the water tank into a certain amount of water, cooling water through the screw type water chiller refrigeration system, by our cold water pump will be cooling water into cooling equipment, screw chillers chilled water will take away the heat temperature rise back to the water tank, achieve cooling effect. Long term use will save water, and the use of the process, the water temperature will be automatically adjusted.
Screw chiller system is operated by three interrelated systems: refrigerant cycle system, water cycle system, electrical control system.
Screw type cold water machine refrigerant circulation system: the liquid refrigerant in the evaporator absorbing heat from the water and began to evaporate, and ultimately refrigerant between the water and the formation of a certain temperature difference, the liquid refrigerant to complete evaporation of gas is sucked into the compressor and compression (pressure and temperature increase, the gaseous refrigerant through the condenser (air / water) heat absorption and condenses into liquid, through the thermal expansion valve or capillary throttle into low-temperature and low-pressure refrigerant into the evaporator, refrigerant cycle process is completed. The refrigeration part of screw chiller, is composed of several core components, compressor, condenser, evaporator, liquid storage, desiccant, thermal expansion valve, the refrigerant. The refrigerant compressor is the source of power, by the input of electrical energy into mechanical energy, the refrigerant absorbs heat in compression, when the state changes and release.
