Description

Technical Field

[0001] The utility model relates to an air source heat pump unit, in particular to an energy-saving air source heat pump unit. Background Art

[0002] The air source heat pump unit is a highly efficient and energy-saving air conditioning device that uses air as a heat source or cold source. It absorbs heat from the outdoor air through a circulating working medium, and then releases the heat to the room through a heat exchanger, thereby achieving heating or cooling of the indoor space. The air source heat pump unit can extract heat from the outdoor air. Compared with the traditional electric heating method, its energy efficiency ratio is higher and it can save a lot of energy. The air source heat pump unit does not need to burn fuel, so it does not produce pollutants such as exhaust gas and smoke, which is environmentally friendly. At the same time, it can also provide a fresh air function to improve the indoor air quality. The heat exchanger used in the existing energy-saving air source heat pump unit is relatively simple in structure, generally a spring-shaped structure, and cold water is input from one end of the heat exchanger and output from the other end. After the refrigerant is pressurized to increase the heat, the outer wall of the heat exchanger is heat exchanged. In this process, the flow rate of cold water is slow, which is not convenient for heating multiple groups of water flows at the same time, which is not conducive to providing hot water discharge and improving work efficiency.

A compressor 200 is fixedly installed on the inner wall of the heating chamber 120, and an output end of the compressor 200 is connected to a heat exchange chamber 220 through a conduit 1 210, and an output end of the heat exchange chamber 220 is connected to a liquid storage tank 240 through a conduit 230, and an output end of the liquid storage tank 240 is connected to an evaporator through a conduit 3 241, and an expansion valve 250 is fixedly installed on the outer wall of the conduit 3 241, and an output end of the evaporator is fixedly connected to an input end of the compressor 200 through a conduit 4 270, and a heat exchanger is fixedly installed on the inner wall of the heat exchange chamber 220.

[0024] The specific usage scenario of this embodiment is: by adding cold water to be heated into the water tank 150, the low-temperature refrigerant refluxed by the compressor 200 is compressed to form a high-temperature and high-pressure gas, and the high-temperature and high-pressure refrigerant gas is transported to the heat exchange chamber 220 through the conduit 1 210. The cooled refrigerant becomes liquid under the continuous action of pressure and then enters the liquid storage tank 240. Then the refrigerant in the liquid storage tank 240 enters the expansion valve and then enters the evaporator, and then enters the evaporator.

[0025] Example 2: Figure 3 and Figure 4 A water tank bracket 140 is fixedly installed on the left outer wall of the unit box body 100, a water tank 150 is fixedly installed on the inner wall of the water tank bracket 140, a water outlet pipe 151 is fixedly installed on the outer wall of the bottom of the water tank 150, a valve 152 is fixedly installed on the outer wall of the water outlet pipe 151, a conduit 5 153 is fixedly installed on the outer wall of the top end of the water tank 150, and a conduit 6 154 is fixedly installed on the outer wall of the bottom end of the water tank 150. The conduit 5 153 and the conduit 6 154 are matched to connect a heat exchanger, and the heat exchanger includes an annular tube 160, two of which are arranged above and below, and the two annular tubes 160 are respectively connected to the conduit 5 153 and the conduit 6 154 through a manifold 161, and a plurality of manifolds 161 are arranged, and the manifolds 161 are distributed in a circular array, the conduit 5 153 and the conduit 6 154 are matched to and fixedly connected with the center positions of the manifolds 161 at the upper and lower ends, and the two annular tubes 160 are matched to be connected through an inclined tube 162.

[0026] The specific usage scenario of this embodiment is: the water in the water tank 150 is pumped into the conduit six 154, enters the manifold 161 at the bottom through the conduit six 154, and then enters the annular tube 160 at the bottom through the manifold 161, and then the water in the annular tube 160 enters the inclined tube 162, and the cold water flows back to the annular tube 160 at the top from bottom to top, and then enters the manifold 161 at the top through the annular tube 160 at the top, so that the water is heated by the high-temperature and high-pressure refrigerant gas and then transported to the conduit five 153, and then flows back to the water tank 150 through the conduit five 153 to complete the heating of the water. The conduit six 154 is the input end of the heat exchanger, and the conduit five 153 is the output end, so that the water can stay in the heat exchanger for a longer time.

[0027] Example 3: Figure 2 and Figure 5 A filter screen 131 is fixedly installed on the outer wall of the heat absorption chamber 130, a cover plate 110 is fixedly installed on the outer wall of the front end of the unit box 100, the evaporator includes a hollow chamber 1 260 and a hollow chamber 2 261, capillaries 262 are evenly fixedly installed between the hollow chamber 1 260 and the hollow chamber 2 261, a fan rack 263 is fixedly installed on the outer walls of the hollow chamber 1 260 and the hollow chamber 2 261, and a fan 264 is evenly fixedly installed on the inner wall of the fan rack 263.

[0028] The specific usage scenario of this embodiment is: the refrigerant in the liquid storage tank 240 enters the evaporator after entering the expansion valve, and then enters the evaporator after the expansion valve. Therefore, the liquid refrigerant quickly evaporates here and becomes gaseous, absorbing a large amount of heat. At the same time, under the action of the fan 264, a large amount of air flows through the surface of the evaporator, and the heat in the air is absorbed by the evaporator. Then the refrigerant that has absorbed a certain amount of energy flows back to the compressor.

[0029] The working principle of the utility model is as follows: when in use, a person skilled in the art adds cold water to be heated into the water tank 150, and the low-temperature refrigerant refluxed by the compressor 200 is compressed to form a high-temperature and high-pressure gas, and the high-temperature and high-pressure refrigerant gas is transported to the heat exchange chamber 220 through the conduit 1 210, and the water in the water tank 150 is pumped into the conduit 6 154, and enters the manifold 161 at the bottom through the conduit 154, and then enters the annular tube 160 at the bottom through the manifold 161, and then the water in the annular tube 160 enters the inclined tube 162, and the cold water flows back from bottom to top to the annular tube 160 at the top, and then enters the annular tube 160 at the top through the annular tube 160 at the top. In the manifold 161, the water is heated by the high-temperature and high-pressure refrigerant gas and then transported to the conduit five 153, and then flows back to the water tank 150 through the conduit five 153 to complete the heating of the water. The cooled refrigerant becomes liquid under the continuous action of pressure and then enters the liquid storage tank 240. The refrigerant in the liquid storage tank 240 then enters the evaporator after the expansion valve, and then enters the evaporator. Therefore, the liquid refrigerant quickly evaporates here and becomes gaseous, absorbing a large amount of heat. At the same time, under the action of the fan 264, a large amount of air flows over the surface of the evaporator, and the heat in the air is absorbed by the evaporator. Then the refrigerant that has absorbed a certain amount of energy flows back to the compressor and enters the next cycle.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
