The main configurations of water-cooled chillers are: compressors, electrical components, water pumps, evaporators, condensers, high/low pressure controllers, high/low pressure gauges, LCD thermostats, expansion valves, antifreeze switches, hand valves , Fan. Screw chillers and high-precision constant temperature circulating chillers are trusted by well-known international and domestic vacuum instruments, analytical instruments, and other manufacturers.
Water circulation system of water-cooled chiller:
First inject a certain amount of water into the water tank of the chiller, cool the water through the chiller refrigeration system, and then send the low-temperature cooling water to the equipment that needs to be cooled by the water pump. The chilled water will take away the heat and increase the temperature before returning to The water tank achieves the cooling effect. The cooling water temperature can be automatically adjusted according to requirements, and long-term use can save water. Therefore, the chiller is a standard environmentally friendly and energy-saving equipment.
Refrigerant circulation system of water-cooled chiller:
The liquid refrigerant in the evaporator absorbs the heat in the water and starts to evaporate. Eventually, a certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant is also completely evaporated and becomes a gaseous state, which is sucked by the compressor and compressed (pressure and temperature increase) , The gaseous refrigerant absorbs heat through the condenser (air-cooled/water-cooled), condenses into a liquid, and is throttled by a thermal expansion valve (or capillary tube) to become a low-temperature and low-pressure refrigerant to enter the evaporator, completing the refrigerant cycle process.
