[0002] In today's growing emphasis on energy use and environmental protection, developing efficient, environmentally friendly and safe heating equipment has become an inevitable trend of industry development. As an advanced heating technology, air source heat pump stands out among many heating equipment with its unique advantages. Air source heat pump uses high potential energy to make heat flow from low potential heat source (such as ambient air) to high potential heat source, realizing efficient conversion of energy, and without using fuel, producing flame and emitting toxic and harmful exhaust gas in the whole process, so it has no pollution to the environment in the heating process, and avoids the safety risks that may be caused by traditional heating methods such as fire, explosion and poisoning, showing high environmental protection and safety.

[0003] In the operation process of air source heat pump, heat in the air is mainly used for heating, and electric power is only used as the power source for the operation of compressor, rather than the main heating energy, which makes the power consumption of air source heat pump much lower than that of traditional electric heating equipment when heating. According to statistics, the power consumption of air source heat pump is only one fourth of that of ordinary electric boiler, so it performs well in energy saving and becomes the preferred solution for energy saving and emission reduction.

[0004] However, although air source heat pump has many advantages, there are still some problems to be solved in practical application. In the design of most air source heat pumps on the market at present, circulating water pump and expansion tank are usually placed outside the main machine, which needs to be purchased and installed by the user separately, which not only increases the cost of the user, but also may cause performance degradation or safety hazards due to improper installation. In addition, in some areas with poor water quality, air source heat pumps using plate heat exchanger as heat exchange component are prone to problems of dirty blockage and freeze cracking, which not only affects the heating efficiency of the equipment, but also may shorten the service life of the equipment and increase the maintenance cost.

[0024] As Figure 4 and Figure 5 also include first water inlet pipe and second water inlet pipe, the first water inlet pipe is communicated with water inlet 12 and the water inlet end of circulating water pump 5, the second water inlet pipe is communicated with the water outlet end of circulating water pump 5 and the water inlet end of high -efficient tank 6, the first water inlet pipe and second water inlet pipe are connected with circulating water pump 5 using a movable joint 122, the movable joint 122 can facilitate the installation of circulating water pump 5, the water inlet end of circulating water pump 5 is arranged on the upper side of the water outlet end, so that the circulating water pump 5 is installed vertically in the lower installation cavity, and the vertical installation mode of circulating water pump 5 can better protect the circulating water pump 5 from water accumulation when not in use, prolonging the service life.
