Description

Technical Field

[0001] This utility model relates to the field of heat pump equipment technology, and in particular to an air source heat pump module that can be arranged in a tower and a tower air source heat pump. Background Technology

[0002] An air source heat pump is a heat exchange device that uses a refrigeration cycle to transfer low-grade heat energy from ambient air to indoor or process heating areas. Its core idea is to use relatively small electrical works to drive a compressor, enabling a low-temperature heat source to achieve high-temperature heat energy output through phase change and compression. The main cycle is a vapor compression refrigeration cycle, which includes four basic processes: evaporation, compression, condensation, and expansion.

[0003] Evaporation (heat absorption): Low-temperature, low-pressure refrigerant absorbs heat from the air in the evaporator (exchanging heat with the outdoor air) and vaporizes into low-temperature steam.

[0004] Compression (heating and pressurization): The compressor compresses low-temperature, low-pressure vapor into high-temperature, high-pressure vapor, increasing the temperature and enthalpy of the refrigerant.

[0005] Condensation (heat release): The high-temperature and high-pressure refrigerant releases heat in the condenser (exchanging heat with indoor air or heating / domestic hot water system), condenses into a high-pressure liquid, and releases heat to the heated medium.

[0006] Expansion (pressure reduction and temperature reduction): The liquid refrigerant is depressurized and cooled through the throttling valve or expansion device, and then returns to the evaporator to complete the next cycle.

[0007] The current air source heat pump installation method uses a planar array, which has the following main problems that need to be solved:

[0008] The equipment occupies a large area: Air source heat pump units generally require sufficient space at the front, back, and sides to ensure air circulation and maintenance. When multiple units are installed side-by-side, a passageway should also be provided in the middle for operation inspection, maintenance, component replacement, and emergency repairs. The width of the passageway should be sufficient for personnel to carry tools and spare parts, which results in air source heat pumps requiring a large floor space for installation.

[0009] Cold (Heat) Island Effect: When a large number of air source heat pumps operate in the same area, they concentrate cold emissions (heating mode) or hot emissions (cooling mode) in certain areas, altering the local microclimate and forming "cold islands / heat islands." This is especially noticeable in winter or at night, potentially causing frost or freezing on surrounding ground or icy roads, affecting pedestrians. Simultaneously, the formed "cold islands / heat islands" can affect the normal operation of the units, leading to reduced efficiency and, in severe cases, causing the units to shut down for protection. Utility Model Content

[0010] The purpose of this invention is to provide an air source heat pump module that can be arranged in a tower and a tower-type air source heat pump, so as to solve the problems existing in current air source heat pumps.

[0011] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0012] This utility model discloses a tower-type air source heat pump module, including a frame. Several heat pump circulation systems are arranged horizontally inside the frame. Each heat pump circulation system includes an evaporator assembly, a thermal insulation and soundproofing structure, and a core component of the heat pump system disposed within the thermal insulation and soundproofing structure. The thermal insulation and soundproofing structure is disposed below the evaporator assembly. Several heat pump circulation systems share a shell-and-tube heat exchanger. The frame is provided with inlet and outlet water ports that communicate with the shell-and-tube heat exchanger.

[0013] Furthermore, the evaporator assembly includes two finned heat exchangers arranged in a V-shape, and several fans are provided on the air outlet side of the finned heat exchangers.

[0014] Furthermore, a baffle plate is provided on the upper part of the finned heat exchanger, and / or a baffle plate is provided on the lower part of the finned heat exchanger.

[0015] Furthermore, the core components of the heat pump system include a liquid receiver. The shell-and-tube heat exchanger is provided with a first connecting pipe and a second connecting pipe. The first connecting pipe is connected to the liquid receiver. A four-way reversing valve is provided on the second connecting pipe. The four-way reversing valve is connected to a vapor-liquid separator, a compressor, and the finned heat exchanger via pipes. The compressor return port is connected to the vapor-liquid separator via a pipe. The compressor is connected to the fourth interface of the economizer via a pipe. The second interface of the economizer is connected to the finned heat exchanger via a pipe. A main electronic expansion valve is provided on the pipe between the finned heat exchanger and the second interface of the economizer. The pipe between the second interface of the economizer and the main electronic expansion valve is connected to the third interface of the economizer via an auxiliary electronic expansion valve. The first interface of the economizer is connected to the liquid receiver via a pipe.

[0016] Furthermore, at least one electrical control box is installed inside the thermal insulation and soundproofing structure.

[0017] A tower-type air source heat pump includes the aforementioned tower-arrangeable air source heat pump modules. Two or more tower-arrangeable air source heat pump modules are arranged laterally along the mounting base to form a single layer of air source heat pumps. Each layer of air source heat pumps has an air inlet on one side and an air outlet on the other side.

[0018] Furthermore, the tower-arranged air source heat pump module has two or more layers vertically.

[0019] Furthermore, the top of the tower-style air source heat pump module is equipped with a rain and snow cover.

[0020] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0021] The thermal insulation and soundproofing structure of this utility model is placed below the evaporator assembly to prevent these components from affecting the wind protection on the side of the finned heat exchanger; multiple heat pump circulation systems are arranged horizontally inside the frame to reduce the amount of engineering work for on-site module connection; the air source heat pump module that can be arranged in a tower can adopt a tower arrangement to reduce the floor space, avoid the formation of "cold island / heat island", and improve the overall operating efficiency.

Several heat pump circulation systems share a shell-and-tube heat exchanger 3-7, which can reduce the installation of a water system. The frame 1 is provided with inlet and outlet water ports 4 that communicate with the shell-and-tube heat exchanger 3-7.

[0036] like Figure 2 As shown, the evaporator assembly 2 includes two finned heat exchangers 2-1, which are arranged in a V-shape. Four fans 2-2 are provided on the air outlet side of the finned heat exchangers 2-1, and the four fans 2-2 are distributed in a rectangular shape.

[0037] A baffle plate 2-3 is provided on the upper part of the finned heat exchanger 2-1, and / or a baffle plate 2-3 is provided on the lower part of the finned heat exchanger 2-1.

[0038] like Figure 3 , 11As shown, the core component 3 of the heat pump system includes a liquid receiver 3-8.
