Efficient low loss fins, larger heat exchange, CFD optimized design more efficient hot water duct plating machine, high winds and low noise. Through CFD design optimization, improved air can change channel split hot water heater, the unit in the unit time to have more air and heat exchangers for heat exchange. In addition, after the design optimization of the blades, which are not the wind noise level increases with increasing amount of hot water office, still remained at a low level. Air to water heaters, heat pump water heaters, also known as also known as air-source water heater, is a "heat transport" means refrigeration principle to absorb heat from the air to produce hot water. Let the working fluid through continuous complete evaporation (absorb heat in the environment) → compression → condensation (gives off heat) → throttle → thermodynamic cycle process re-evaporation, thereby environments where heat is transferred to the water. Split water heater, the more Han Technology, Pingyang hot water provided by the Han Technology Co., Ltd., Henan. Henan Science and Technology Co., the Han (www.hnlyjd.com/) is Zhengzhou, electronics, electrical products processing leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the Han technology leadership with the staff warmly welcome all inquiries negotiations to create the Han technology a better future.
