Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to an air conditioning unit with a built-in water pump. Background Technology

[0002] With the acceleration of urbanization and the popularization of green building concepts, the market has placed higher demands on the energy efficiency of building air systems. At the same time, the construction industry urgently needs to find a balance between shortening construction cycles and improving building quality to meet the needs of efficient and low-carbon development.

[0003] Currently, as the core equipment of air handling units (AHUs), traditional designs require water pumps, which serve as the power source for the hot and cold water circulation system, to be independently installed in a dedicated pump room. The main functions of the pumps include: providing the power for the flow of hot and cold water in the heat exchange sections of the AHU (such as chilled or hot water coils) to ensure heat exchange efficiency; and controlling the operating parameters of the hot and cold water piping network to match the building load requirements. In traditional solutions, the water pumps need to be independently installed in a dedicated pump room, occupying a large amount of building space and increasing the complexity and cost of building design. Although factory prefabrication can reduce some on-site work, the separate installation of the water pumps and AHUs still requires additional piping connections, valve debugging, and machine room construction, making it difficult to further shorten the construction period. Long-distance hot and cold water piping increases heat loss and fluid resistance, reducing the overall energy efficiency of the system. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an air conditioning unit with a built-in water pump, which has the characteristics of compact structure and high integration.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] An air conditioning unit with a built-in water pump includes a cabinet. The cabinet includes an air inlet chamber, a filter chamber, a heat exchange chamber, and a fan chamber, which are arranged sequentially on the left and right and connected to each other. A water coil is installed in the heat exchange chamber, and a water pump chamber is located on one side of the heat exchange chamber. A water pump assembly connected to the water coil is installed in the water pump chamber, and the water pump assembly can drive the water circulation in the water coil. The water pump chamber is embedded in the front side of the cabinet.

[0007] The front of the cabinet is equipped with cabinet doors for the air inlet chamber, filter chamber, and fan chamber, respectively, and the front of the water pump chamber is also equipped with a cabinet door.

[0008] The water pump assembly includes a main pipe arranged vertically, on which a water pump is installed; the upper end of the main pipe extends out of the upper side of the cabinet to form a water inlet, the lower end of the main pipe is connected to one end of a water coil, and the other end of the water coil extends to the upper side of the cabinet to form a water outlet.

[0009] A bypass channel is provided on one side of the main pipeline, and the two ends of the bypass channel are connected to the main pipeline at the upper and lower ends of the water pump.

[0010] A bypass valve is installed on the bypass channel, and a drain valve is installed at the lower end of the main pipeline.

[0011] The cabinet contains a control room, and the control room contains a controller.

[0012] The control room is embedded in the cabinet, and a cabinet door is provided on one side of the control room.

[0013] An air intake regulating valve that communicates with the air intake chamber is installed above the air intake chamber.

[0014] A filter is installed in the filtration chamber.

[0015] The fan room is equipped with a fan assembly, and the fan room is connected to an air outlet duct.

[0016] The beneficial effects of this utility model are:

[0017] 1. Traditional solutions require a separate pump room (typically occupying 5%-10% of the equipment floor area), while this air conditioning unit embeds the pump room within the cabinet, compactly integrating it with the heat exchange room, thus saving the need for a separate pump room. The pump components and water coils are connected in-house, achieving "complete unit delivery," which reduces costs and improves construction efficiency.

[0018] 2. All functional rooms, such as air intake room, water pump room, fan room and control room, are located on the front side of the cabinet and have cabinet doors. This makes it convenient for the layout of air ducts and water and electricity pipes of the equipment, as well as for later maintenance and repair, which improves installation efficiency and facilitates maintenance and repair.

[0019] 3. The water pump assembly is integrated into the water pump room inside the cabinet. The water pump is directly connected to the water coil through the main pipeline. Compared with the traditional separate water pump room, the flow path length is reduced by more than 60% and the heat loss is reduced to 3%-5%. The bypass valve and drain valve realize load adaptive control to avoid water pump overload energy consumption, which improves the overall comprehensive energy efficiency by 15%-20% and reduces the annual operation and maintenance cost by about 18%.

[0024] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0025] Reference Figure 1-3 This utility model proposes an air conditioning unit with a built-in water pump, including a cabinet 1. The cabinet 1 includes an air inlet chamber 2, a filter chamber 3, a heat exchange chamber 4, and a fan chamber 5, which are arranged sequentially on the left and right and connected to each other. A water coil 60 is provided in the heat exchange chamber 4, and a water pump chamber 40 is provided on one side of the heat exchange chamber 4. A water pump assembly connected to the water coil 60 is installed in the water pump chamber 40, and the water pump assembly can drive the water circulation in the water coil 60. The water pump chamber 40 is embedded in the front side of the cabinet 1.

[0026] Specifically, this air conditioning unit embeds the water pump room within the cabinet, compactly integrating it with the heat exchange chamber, thus saving the need for a separate water pump room. Traditional solutions require a separate water pump room, while in this design, the water pump components and water coils are connected in-house, achieving "complete unit delivery," which reduces costs, improves construction efficiency, and saves on layout space.

[0027] Reference Figure 3 Cabinet 1 has cabinet doors 10 on the front side corresponding to air inlet chamber 2, filter chamber 3, and fan chamber 5, and cabinet doors 10 are also provided on the front side of water pump chamber 40.

[0028] Specifically, all functional rooms, such as air intake room 2, water pump room 40, fan room 5, and control room 31, are located on the front side of cabinet 1 and all have cabinet doors 10. This makes it more convenient for the layout of the equipment's air ducts and water and electricity pipes, as well as for later maintenance and repair, thus improving installation efficiency and facilitating maintenance and repair.

[0029] Reference Figure 2-4 The water pump assembly includes a main pipe 63 arranged vertically, and a water pump 6 is installed on the main pipe 63. The upper end of the main pipe 63 extends out of the upper side of the cabinet 1 to form a water inlet interface 61, and the lower end of the main pipe 63 is connected to one end of a water coil 60. The other end of the water coil 60 extends to the upper side of the cabinet 1 to form a water outlet interface 62.

[0030] Reference Figure 4 A bypass channel 64 is provided on one side of the main pipe 63, and the two ends of the bypass channel 64 are connected to the main pipe 63 at the upper and lower ends of the water pump 6.

[0031] Reference Figure 4A bypass valve 640 is installed on the bypass channel 64, and a drain valve 630 is installed at the lower end of the main pipeline 63.

[0032] Furthermore, the water pump assembly is integrated into the water pump room 40 within the cabinet 1. The water pump 6 is directly connected to the water coil 60 via the main pipe 63. Compared to the traditional separate water pump room, the flow path length is reduced by more than 60%, and the heat loss is reduced to 3%-5%. The bypass valve 640 and the drain valve 630 achieve load adaptive control, avoiding water pump overload energy consumption, thereby improving the overall comprehensive energy efficiency by 15%-20% and reducing annual operation and maintenance costs by about 18%.

[0033] Reference Figure 3 The cabinet 1 contains a control room 31, and the control room 31 contains a controller 32. The control room 31 is embedded in the cabinet 1, and a cabinet door 10 is provided on one side of the control room 31. Optionally, the control room 31 is located in front of the filter chamber 3, and a partition is provided between the control room 31 and the filter chamber 3.

[0034] Furthermore, the pump room 40 and control room 31 are spaces with a large amount of heat generation. They are designed to be embedded in the cabinet 1. The air volume in the cabinet 1 enters from the air inlet 2 and exits from the fan room 5. It can flow through the inner walls of the pump room 40 and control room 31, carrying away some of the heat, thereby achieving a partial heat dissipation effect.

[0035] Reference Figure 2 An air intake regulating valve 20, which is connected to the air intake chamber 2, is installed above the air intake chamber 2.

[0036] Reference Figure 2 A filter 30 is installed in the filter chamber 3.

[0037] Reference Figure 3 The fan room 5 is equipped with a fan assembly 50, and the fan room 5 is connected to an air outlet duct.

[0038] The controller 32 in the control room 32 is a central controller that can monitor the operating status of the water pump assembly and the fan assembly 50 in real time, and intelligently adjust the flow rate to achieve load adaptive control and improve overall energy efficiency.

[0039] In summary, this air conditioning unit integrates components such as water pumps within its internal space, enabling full pre-assembly in the factory and simplified piping design. It systematically overcomes the pain points of traditional solutions, such as space waste, inefficient construction, and high energy consumption, providing an innovative solution for green buildings that combines economy and reliability.
