Screw compressor maintenance organization must find a professional to do, because the technical requirements of this industry is relatively high. Considering what the appropriate chiller maintenance, generally if it is not in a hurry chiller urgently, then it is better able to slowly, but under normal circumstances but also the production process needs of enterprises, so only a hurried panic to find maintenance organizations maintenance crew, then good catch the use, so in this case we must find efficient maintenance organizations, and only skillful to be able to quickly solve the problem. Snow Dragon is such a strong technology, first-class service efficiency refrigeration equipment maintenance organizations engaged in servicing the refrigeration industry for nearly a decade, has a lot of experience in the industry. Is to serve as a center of industrial refrigeration equipment, customer satisfaction for the purpose of the enterprise. Our technology can not boast that more cattle, but for so many years that we have so many user support, sufficient to explain our services are done for. The refrigerant cycle system: evaporator liquid refrigerant absorbs heat in the water and started evaporative cooling equipment parts, eventually formed between the refrigerant and the water temperature difference between certain refrigeration equipment, the liquid refrigerant has completely evaporated into gas, after the compressor suction and compression (pressure and temperature increase) used refrigeration equipment, the gas refrigerant releases heat through the condenser, condenses into a liquid. Through the expansion valve (or capillary tube) after throttling into low temperature low pressure refrigerant into the evaporator, the refrigerant to complete the cycle.
