Description

Technical Field

[0001] The utility model relates to a heat pump utilization technology, in particular to an ultra-quiet air source heat pump for household use. Background Art

[0002] In recent years, the country has vigorously promoted the use of clean energy for cooling and heating, among which high-efficiency heat pump technology, low-temperature energy storage technology and integrated cooling and heating technology are key technologies for replacing electric energy. As a heating equipment, air source heat pumps are increasingly used in heating because they do not pollute the environment like boilers, and at the same time have the functions of refrigeration and air conditioning. Therefore, they are widely used in heating and air conditioning of buildings, and air source heat pumps have become the first choice for people's homes.

[0003] Most of the existing air source heat pump units on the market are integrated units. Integrated air source heat pumps occupy a large area and are heavy, so they are not suitable for residential buildings. In addition, as people's requirements for quality of life increase, higher requirements are placed on the noise of air source heat pump units. Summary of the invention

[0004] The technical problem to be solved by the utility model is to propose a household indoor ultra-quiet air source heat pump with high molding efficiency in view of the deficiencies of the prior art.

[0005] The technical problem to be solved by the utility model is achieved through the following technical solutions, a household indoor ultra-quiet air source heat pump, which is characterized by:

[0006] The outdoor unit is composed of a compressor, an evaporator, a throttling mechanism, a motor and a fan blade as an integrated structure; the indoor unit is composed of a heat exchange water tank, a circulating water pump and an expansion pipe, and the outdoor unit and the indoor unit are connected through a circulating pipeline;

[0007] The indoor unit is provided with a sound-absorbing wall between the water exchange water tank, the circulating water pump and the expansion pipe.

[0008] Compared with the prior art, the utility model adopts a split heat pump, which is divided into an outdoor unit and an indoor unit, which is convenient for use in residential buildings. At the same time, the compressor is placed in the outdoor unit to reduce the impact of the unit operation noise on people's lives. The volume of the air source heat pump unit is reduced to make it suitable for residential buildings. For the indoor unit, in order to reduce the impact of the noise generated when the unit is running on the lives of residents, a soundproofing wall is provided between the heat exchange water tank, the circulating water pump, and the expansion pipe. It can not only reduce the noise when the unit is running, but also have the effect of heat preservation, reduce the heat loss of the heat exchange water tank, and improve the working efficiency of the air source heat pump unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a simplified structural diagram of the utility model. DETAILED DESCRIPTION

[0010] The specific technical solutions of the present invention are further described below. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer and to facilitate those skilled in the art to further understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them, and do not constitute a limitation on the rights thereof. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0011] A household indoor ultra-quiet air source heat pump comprises an outdoor unit 1 and an indoor unit 2, wherein the outdoor unit comprises a compressor, an evaporator, a throttling mechanism, a motor, and a fan blade, and the indoor unit comprises a water exchange tank, a circulating water pump, and an expansion pipe.

[0012] The outdoor unit and the indoor unit are connected to each other through a circulation pipeline;

[0013] The indoor unit is provided with a sound-absorbing wall 3 between the hot water exchange tank, the circulating water pump and the expansion pipe.

[0014] Reduce the size of the air source heat pump unit to make it suitable for residential buildings. The noise of the air source heat pump unit mainly comes from the vibration of the compressor when the unit is running. This application places the compressor in the outdoor unit to reduce the impact of the noise generated when the unit is running on the lives of residents and improve the sleep quality of residents. For the indoor unit, in order to reduce the impact of the noise generated when the unit is running on the lives of residents, a soundproofing wall is installed between the water exchange tank, the circulating water pump, and the expansion pipe. It can not only reduce the noise when the unit is running, but also have the effect of heat preservation, reduce the heat loss of the water exchange tank, and improve the working efficiency of the air source heat pump unit.

[0015] The compressor in the outdoor unit runs, compressing the refrigerant from a low-temperature, low-pressure gas into a high-temperature, high-pressure gas. The high-temperature, high-pressure refrigerant passes through the throttling mechanism and becomes a high-temperature, low-pressure gas. It then enters the indoor unit's water exchange tank to exchange heat with the medium in the water exchange tank. After releasing heat, the low-temperature, low-pressure liquid refrigerant enters the evaporator in the outdoor unit, absorbs heat from the air and becomes a low-temperature, low-pressure gaseous refrigerant. It then enters the compressor. This cycle is repeated to heat the medium in the water exchange tank, thereby achieving the effect of raising the indoor temperature.
