Question 2: What is the difference between air energy water heater and air energy heat pump The same, heat pump water heater and air energy water heater are the same, just a different call. Heat pump is a device that transfers heat energy from a low-temperature heat source to a high-temperature heat source. And not only is the water heater, but also instead of air conditioning and heating, like the domestic Changfeng Taihe is doing a series of air energy heat pump products
Question 3: What does air energy water heater mean? What is the difference with the general electric water heater? Air water heater is in accordance with the "inverse Carnot" principle of work, figuratively speaking, that is, the "outdoor unit" like a pump to compress the air, so that the air temperature rises, and then through a kind of -17 ° C will be boiling liquid conduction of heat to the indoor storage tank, and then release the heat conduction to the water. The heat is then released and transferred to the water. Using the heat pump working principle of heating, as opposed to air conditioning refrigeration - the national standard for refrigeration is 1,000 watts, electric refrigeration 2,800 watts. According to the principle of heat balance, at least 2800 watts of heat at the same time, plus the input of 000 watts of electricity, the actual heat generated in 3000 - 4000 watts, the heat delivered to the holding tank, its power consumption is only a quarter of the electric water heater (electric water heater even if the thermal efficiency of 100%, the input of 1000 electricity, only 1000 watts of heat). (Even if the thermal efficiency of the electric water heater is 100%, the input of 1000 watts of electricity is only 1000 watts of heat). Air water heaters, on the other hand, don't need sunlight, so they can be placed in the home or outdoors. It is difficult to produce hot water as soon as the water stored in a solar water heater is used up. If it takes a long time to heat it electrically, an air water heater can run under pressure 24 hours a day as long as there is air and the temperature is above zero degrees Celsius. In this way, that is, after using a tank of water, an hour or so will produce another tank of hot water. At the same time it can also fundamentally eliminate the electric water heater leakage, dry burning and gas water heater use of harmful gases and other safety hazards, to overcome the solar water heater can not be used on rainy days and the installation of inconvenience and other shortcomings, has a high degree of safety, high energy efficiency, long life, no emission of poisonous gases, and many other advantages. The life of air water heaters can generally reach 15 to 20 years.

The heat pump uses the principle of inverse Carnot to absorb a large amount of low-temperature heat energy in the air with a very small amount of electric energy, which is compressed by the compressor into high-temperature heat energy and transferred to the water tank to heat the hot water, so it is a low energy consumption, high efficiency, high speed, good safety, environmental protection, and a constant supply of hot water. For air source heat pump working principle diagram for hot water system it has incomparable advantages. The heat pump water heater unit follows the law of conservation of energy and the 2nd law of thermodynamics, using the principle of heat pumps, only need to consume a small portion of the mechanical work (electrical energy), will be in a low-temperature environment (the atmosphere or groundwater, etc.) under the transfer of heat to a high-temperature environment of the water heater to heat the hot water heater, to heat up the production of high-temperature hot water. Heat pumps can be compared with water pumps, water can not spontaneously flow from low to high, to transfer water from low to high, you must use a pump, consume a portion of the electricity, in order to send the water to the high tank. Similarly, according to the second law of thermodynamics, heat can not be spontaneously from the low-temperature environment to the high-temperature environment transfer (transfer), and to achieve this purpose, there must be a machine, consume a part of the mechanical work (such as electricity), in order to the low-temperature environment to the high-temperature environment of the heat transfer. Such a machine is called a "heat pump". The role of the heat pump is to take out the heat in the air or low-temperature water, together with its own use of electrical energy into thermal energy, together with the high-temperature environment to the application.
