The basic principle of heat pump water heater: it is mainly by the compressor, heat exchangers, axial fans, holding tanks, pumps, tank, filters, electronic expansion valves and electronic automatic controller and other components. After the power is turned on, the source environment (water, air) can be warmed in a low draw, and then converted to a higher release was warmed to circulating medium (water, air) in a high-temperature heat output. In this work due to the operation of the compressor power is consumed, so that the continuous operation of the compressor circulating refrigerant produced in different systems in different states and different effects change (ie heat evaporation and condensation heat) to It reached a low-temperature heat recovery system to take the role of high temperature heat source and purpose, which is air-source heat pump water heater basically works. The plant is a very hot allow enterprises headache heat pump water heater controller, for two main reasons: 1, plant hot lead to staff dissatisfaction and turnover rate on the environment. 2, left to the employees who work inefficiency school environment sultry heat pump water heaters, poor quality, causing the company losses. 3, a large workshop space, use air-conditioning heat pump water heater to improve the environment, energy cost and equipment investment are high, corporate profits is difficult to have enough support. 4, environmental conditioning more power, but the lack of cool, spend no effect, employees or dissatisfied. But the increase in national income, under recruitment difficulties and improve the work environment becomes necessary, does not improve the final recruit workers, the company has only to close one way. If dual-source heat pump water heaters, hot water production plants need to use or hot air. Really worthy of congratulation, then you can use "super-industrial heat pumps" address the interference. What is a heat pump water heater, the Han Technology, Leishan heat pump hot water provided by the Henan Science and Technology Co., Ltd. Han Yue. Henan Yue Han Technology Co., Ltd. (www.hnlyjd.com/) is Zhengzhou, electronics, electrical products processing leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Science and technology leader in the culvert with the staff warmly welcome all inquiries negotiations to create the Han Technology better future.
