Nowadays, gas water heaters, electric water heaters are commonly used in most domestic household bath. These bath sets are convenient for people and pose a threat to people's safety. Not long ago, an energy saving, safe air source heat pump water heater came out in Huaiyin, Jiangsu. This water heater, Zhejiang Region promoter Yu said: "Its most prominent feature is the use of heat pump technology to absorb air energy hot water, very energy-saving.If you heat the same volume of hot water, this water heater power consumption only ordinary Electric water heater 1 / 2-1 / 4. And, because of its work outside the machine with the reservoir belong to two places, but also to solve the leakage and other safety issues. "Exchanging heat through the medium air source heat pump water heaters also need electricity , But it is driven by electric energy to start the heat pump of the external machine. Under the work of the heat pump, a large amount of liquid medium (Freon) in the external machine starts to absorb the heat energy in the air and then rapidly transforms to the gaseous state and is transmitted to the high-pressure pipe Indoor water storage brass. At this moment, the copper tube in the high temperature state contacts the cold water in the water storage device, and transmits the heat energy, and then transforms into the liquid state, and returns to the outside machine through the other high-pressure tube. "The medium is driven by the heat pump and goes on and on again. The indoor water reservoir also absorbs heat continuously in such a cycle, resulting in hot water." Mr. Yu said air-source heat pump water heaters do not make heat directly from electricity, It produces more than 3.6: 1 thermal energy and consumes more electricity, "and consumes 1 / 2-1 / 4 of normal water heaters for a fixed daily water consumption." According to Mr.You introduction, this new water heater specifications from 0.7 kilowatts to 100 kilowatts, to meet the family, hair salon, as large as schools, hotels, military camps, public baths and other large amount of hot water usage requirements of various users ; And the installation is not limited to buildings and floors. In addition, due to the air source heat pump water heater used to exchange heat, so there will be no leakage, leakage caused by accidents. "As long as the outdoor temperature reaches minus 5 ℃ above, it can be used, and the time to produce hot water above 50 ℃ will not exceed 30 minutes." Mr. Yau said that this air source heat pump water heater is very suitable for southern users.
