Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, and in particular to a heat pump accessory device with a vertically arranged water flow natural circulation system. Background Technology

[0002] An air source heat pump, also known as an air-source heat pump, is a device that uses heat from the air to generate heat energy. It uses a compressor system to absorb heat from the air to produce hot water. Specifically, the compressor compresses the refrigerant; the heated refrigerant then passes through a condenser in a water tank to produce hot water. The refrigerant, after heat exchange, returns to the compressor for the next cycle. In this process, heat from the air is absorbed by the evaporator and transferred to the refrigerant, which is then transferred to the water to produce hot water.

[0003] As a key component of air source heat pumps, the water tank is typically mounted horizontally alongside the heat pump in existing technologies, consuming considerable space. Furthermore, in winter, when the equipment malfunctions and shuts down, the water inside the heat pump easily freezes due to low outside temperatures, potentially damaging the pump and rendering it ineffective at preventing freezing. Therefore, this invention proposes a vertically arranged, naturally circulating water system for the heat pump to address these shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a vertically arranged, naturally circulating water heat pump device. By installing the air source heat pump on the top of the integrated module housing through a connecting mechanism, the buffer water tank and the air source heat pump are arranged vertically, effectively saving space. Hot water in the buffer water tank can rise to the air source outlet and enter the air source heat pump, while cold water in the air source heat pump flows into the buffer water tank through the air source inlet and the second circulation pump. The density difference of water is used to achieve natural water circulation, thus achieving an antifreeze effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vertically arranged, naturally circulating heat pump system includes an integrated module housing, a buffer water tank, and an air-source heat pump. The air-source heat pump is mounted on the top of the integrated module housing via a connecting mechanism. An air-source water inlet and an air-source water outlet are located on one side of the air-source heat pump. The buffer water tank is located inside the integrated module housing. A first circulation pump, a second circulation pump, and a pressure-regulating tank are located at the front of the buffer water tank. The first and second circulation pumps are connected to the buffer water tank via connecting pipes. The pressure-regulating tank is connected to the buffer water tank via a pressure-regulating pipe. One end of the buffer water tank is connected to the air-source water outlet. A first pipe and a second pipe are located at the top inside the integrated module housing. An indoor water outlet and an indoor water return are located on the outer wall of one side of the integrated module housing. One end of the first pipe is connected to the first circulation pump, and the other end of the first pipe is connected to the indoor water outlet. One end of the second pipe is connected to the second circulation pump, and the other end of the second pipe is connected to the air-source water inlet. One end of the buffer water tank is connected to the indoor water return.

[0007] A further improvement is that: a drain pipe is provided on the connecting pipe, a drain valve is provided on the drain pipe, a first ball valve is provided on the connecting pipe, and a second ball valve is provided on the constant pressure pipe.

[0008] A further improvement is that the inner wall of the integrated module box is provided with thermal insulation cotton.

[0009] Further improvements are made in that: the connecting mechanism includes a platform and a positioning seat; the top of the integrated module housing is provided with a platform; the top of the platform is provided with a flow guide groove; the interior of the flow guide groove is provided with a positioning seat; there are four sets of positioning seats; the positions of the four sets of positioning seats are adapted to the positioning blocks at the bottom of the air source heat pump.

[0010] A further improvement is that: the flow guide groove is symmetrically and rotatably provided with a bidirectional screw, one end of the bidirectional screw is provided with a knob, the bidirectional screw is symmetrically and threadedly connected with a connecting rod, the flow guide groove is symmetrically provided with a guide groove, and the bottom of the connecting rod is slidably connected to the guide groove.

[0011] A further improvement is that a positioning pin is provided on the inner side of one end of the connecting rod, and the positioning seat and the positioning block are provided with insertion holes that are adapted to the position of the positioning pin.

[0012] A further improvement is that a water guide hole is provided in the middle of the guide channel, a water guide pipe is laid inside the platform, one end of the water guide pipe extends to one side of the platform, and the other end of the water guide pipe is connected to the water guide hole.

[0013] The beneficial effects of this utility model are as follows: This utility model installs the air source heat pump on the top of the integrated module box through a connecting mechanism, and then installs the buffer water tank, the first circulation pump, the second circulation pump, the pressure tank, the first pipe and the second pipe inside the integrated module box, so that the buffer water tank and the air source heat pump are arranged vertically, which can effectively save space.

[0014] In this invention, after the heat pump fails and stops in winter, the hot water in the buffer tank can rise to the air source heat pump outlet and enter the air source heat pump. Meanwhile, the cold water in the air source heat pump flows into the buffer tank through the air source inlet and the second circulation pump. The hot water stored in the buffer tank has a higher temperature and a relatively lower density. By utilizing the density difference of the water, the water can circulate naturally, achieving an antifreeze effect and assisting the air source heat pump in achieving its antifreeze function.
