Heat pump water heater pipe heat exchanger

★ withstand shock, not deformed refrigeration system in actual operation due to temperature fluctuations, start-stop cycle, the heat pump defrosting, expansion valve adjustment and other complex factors affect, the internal pressure is always in frequent alternation process. At higher or frequent changes of pressure, pressure shock resistant helical bundle structure and ability to withstand pressure is much higher than the sheet structure. Therefore, the refrigeration system can adapt to the actual operating conditions of complexity. ★ dirt dirt-resistant, stable due to the spiral tube heat exchanger heat transfer tube bundle using specific spiral structure, which is designed so that the heat transfer tubes water side flow channel having a larger cross-sectional size, can tolerate greater water sand, fibers and other impurities by diameter, resulting in the possibility of blockage of the small, but because of the possibility of blockage caused by hard water is small, due to the long run and will not cause a substantial decline in heat transfer performance and waterways clogged, So meet the water quality tube heat exchanger stronger, stable and reliable system operation.
