Editor's Note: To enable readers to better understand the new energy-saving technologies and new technologies, the city of energy-saving monitoring technology service center screening, we start from today, according to the types of products introduced "energy-saving products live show," the topic of science reports, describes the scientific principles , Together with the upcoming exhibitors and product list. In recent years, heat pump water heaters to recover low temperature waste heat, energy saving advantages, by people of all ages. As a new type of air heating equipment, heat pump water heater to produce hot water, the cost of energy consumption is only 1/4 of conventional electric water heaters, fuel, gas equipment, 1/3, large-scale use will greatly reduce the community Demand for heating energy. For example, an ordinary urban household uses 200 liters of daily hot water at 60 ℃ as an example. If using an electric water heater to heat it (calculated according to the hot water temperature of 40 ℃), the daily electricity consumption is about 11.6 degrees, which is equivalent to 5.3 yuan of electricity charges. Cost about 1925 yuan; if the use of air-source heat pump water heaters, daily consumption of about 2.6 degrees, equivalent to 1.53 yuan electricity, the annual cost of about 550 yuan, compared with the traditional electric water heater can save at least 1375 yuan a year. Heat pump system is mainly composed of 4 parts, namely, compressor, condenser, expansion valve, evaporator. Like the refrigerator, the heat pump utilizes the compressor to drive the circulation of the refrigerant in the pipeline to continuously evaporate and condense. After absorbing the temperature difference between the refrigerant and the compressor, the heat is gathered continuously. The working principle is that the refrigerant absorbs the temperature of the outside and evaporates, compressing the heat by the compressor to become a high-temperature and high-pressure gas, and then exchanges heat with the water through the heat exchanger, releasing pressure through the expansion valve, returning to liquefaction at a low temperature and a low pressure State, the water in the tank is heated by the constant circulation of the refrigerant and the exchange of heat with the water. Hot water through the water circulation system into the user radiator for heating or direct use for hot water supply.
