Description

Technical Field

[0001] This utility model relates to a heat pump, and more particularly to a containerized water source heat pump. Background Technology

[0002] A water source heat pump is an air conditioning technology that utilizes the solar energy resources stored in the Earth's water as a cold and heat source. A water source heat pump typically includes a compressor, evaporator, condenser, and expansion valve.

[0003] Existing water source heat pumps typically require different sized main units to be designed based on varying steam demand, resulting in long development cycles and high labor costs. Furthermore, the types of components required for different sized main units vary considerably, leading to poor structural consistency. Conventional water source heat pump main units also have limited installation space, making after-sales maintenance difficult.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to solve the problem that current water source heat pumps are usually designed with different sizes of water source heat pump main units according to different steam demand, and the structures of water source heat pumps of different sizes are quite different, resulting in poor structural consistency of water source heat pumps with different steam volumes and long development cycles.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] The containerized water source heat pump includes a main body, multiple heat pump modules, a water manifold, a control cabinet, and a power cabinet. Multiple heat pump modules are arranged sequentially along the length of the main body, and each module is detachably connected to the main body. A water manifold connects to the upper part of the main body, and all heat pump modules are connected to this manifold. The control cabinet is electrically connected to each heat pump module, and the power cabinet is also electrically connected to each heat pump module. The control cabinet and power cabinet are located inside the main body and on one side of each heat pump module.

[0008] In this invention, the number of heat pump modules that can be activated can vary depending on the heating demand, or the size of the unit can be changed as needed, eliminating the need to design different sizes of water source heat pump main units based on different steam volume requirements. The containerized water source heat pump of this invention is suitable for different heating demand situations, and the heat pump modules have uniform specifications, which can save a lot of development time and labor costs. At the same time, a single heat pump module can also be used with the control cabinet and power cabinet to form an independent main unit, making it more adaptable.

[0009] If heat pump components are directly installed inside the machine body, installation and maintenance are usually difficult due to limited installation space. This invention allows for the offline assembly of individual heat pump modules, which are then sequentially installed inside the machine body, saving assembly time.

[0010] Preferably, the bottom of the heat pump single module includes multiple T-shaped fixing blocks, the bottom surface of the unit is connected to multiple mounting beams, the top surface of the mounting beams is provided with a sliding groove, the T-shaped fixing blocks are inserted into the mounting beams and slidably connected in the sliding grooves; the first bolt passes through the mounting beams and the T-shaped fixing blocks in sequence and is then connected to the wing nut.

[0011] The tightening direction of the first bolt in this invention avoids the direction of vibration, eliminating the need to consider the problem of nut loosening. A wing-type hand-tightening nut can be used for tightening, increasing the convenience of after-sales maintenance. Disassembly and installation can be completed without tools. This installation method offers good stability and high strength. Furthermore, the slot design facilitates installation, minimizes installation errors, and increases structural stability during transportation and operation.

[0012] Preferably, the mounting beam includes multiple sets of mounting holes in the horizontal direction, and the T-shaped fixing block includes a through fixing hole in the horizontal direction. When the fixing hole is aligned with the mounting hole, the first bolt passes through the mounting hole and the fixing hole from one side of the mounting beam and is then connected to the wing nut.

[0013] Preferably, the T-shaped fixing blocks of each heat pump module are arranged in multiple columns, with each column including at least two T-shaped fixing blocks.

[0014] Preferably, a shock-absorbing pad is also connected between the bottom of the heat pump module and the mounting connection.

[0015] Reduce vibration and noise.

[0016] Preferably, each heat pump module includes a mounting bracket arranged in two layers along the vertical direction, with the condenser connected to the upper layer of the mounting bracket and the evaporator connected to the lower layer of the mounting bracket.

[0017] Preferably, the side of the mounting frame includes multiple lifting lugs, and the bottom surface of the mounting frame has a forklift mounting position.

[0018] Preferably, the body includes multiple top plates, and the top of the body includes multiple mounting windows arranged in a matrix, with one side of the top plate hinged to the edge of the mounting window.

[0019] Preferably, the machine body also includes a pneumatic rod located below the top plate, with the fixed end of the pneumatic rod connected to the top of the machine body and the telescopic end of the pneumatic rod connected to the bottom surface of the top plate.

[0020] Preferably, a folding handle is also connected to one side of the top surface of the top plate.

[0021] The partitioned layout of the heat pump unit allows the top plate to remain stationary at any angle within the design range under the action of the pneumatic rod, facilitating maintenance personnel to enter the cabin for operation; the rotating mechanism design reduces assembly errors caused by traditional screw fixing, increasing the convenience of production, installation and maintenance.

[0022] The advantages of this utility model are:

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Example 1:

[0041] like Figure 1 , Figure 2 As shown, the containerized water source heat pump includes a main body 1, multiple heat pump modules 2, a water manifold 3, a control cabinet 4, and a power cabinet 5. The multiple heat pump modules 2 are arranged sequentially along the length of the main body 1, and are detachably connected to the main body 1. The water manifold 3 is located at the top inside the main body 1, and all heat pump modules 2 are connected to the water manifold 3. The control cabinet 4 is electrically connected to each heat pump module 2, and the power cabinet 5 is electrically connected to each heat pump module 2. The control cabinet 4 and power cabinet 5 are arranged vertically and are located on the left side inside the main body 1.

[0042] The heat pump module 2 is placed inside the body 1 and fixed to the mounting beam 11 of the body 1, such as... Figure 2As shown, the unit includes five heat pump modules 2. Each heat pump module 2 is connected to a water manifold 3 via branch pipes for heat source recovery and heating of the entire unit. Braided flexible hoses are used at the outlet of the branch pipes to reduce installation errors with the water manifold 3. A butterfly valve is added between the branch pipes and the water manifold 3 for water circuit control of the heat pump module 2. A power cabinet 5 and a control cabinet 4 are located on the left side for power supply and linkage control of the modules. The power cabinet 5 and control cabinet 4 can be connected to the unit body 1 via bolts or welding.

[0043] The overall appearance of the machine body 1 mimics that of a shipping container, employing a corrugated plate assembly structure, resulting in a harmonious and aesthetically pleasing overall design. Multiple casters 15 are connected to the bottom of the machine body 1 for easy movement.

[0044] Specifically, multiple mounting beams 11 are connected to the bottom surface inside the body 1. These mounting beams 11 are arranged in parallel and can be fixed to the bottom surface inside the body 1 by welding. The mounting beams 11 are through-beams along their length, and mounting grooves are formed on the top surface of each mounting beam 11 along its length. Multiple mounting holes are formed on the sides of each mounting beam 11, and the mounting holes on both sides of each mounting beam 11 are located on the same axis.

[0045] like Figure 3 , Figure 4 As shown, the bottom of each heat pump module 2 is connected to at least two mounting beams 11, which are respectively supported on both sides of the heat pump module 2. Correspondingly, each heat pump module 2 includes multiple T-shaped fixing blocks 21. The T-shaped fixing blocks 21 are inverted, with their tops placed in the mounting groove and their bottoms located inside the mounting beams 11, allowing them to slide along the mounting groove. A through fixing hole is formed at the bottom of the T-shaped fixing block 21. When the fixing hole aligns with the mounting hole, the position of the heat pump module 2 is fixed by mounting the first bolt 22 and the wing nut 23. Each heat pump module 2 includes at least four T-shaped fixing blocks 21, which form two rows, and the two rows of T-shaped fixing blocks 21 are respectively connected to the mounting beams 11.

[0046] In existing fixing methods, bolts and nuts require torque tightening to increase the tightening force and prevent loosening. Specific tools are still needed for maintenance, disassembly, and installation. In this embodiment, the tightening direction of the first bolt 22 avoids the vibration direction, eliminating the need to consider nut loosening. A butterfly nut can be used for tightening, increasing the convenience of after-sales maintenance and allowing for disassembly and installation without tools. This installation method offers good stability and high strength. Furthermore, the slotted design facilitates installation, minimizes installation errors, and increases structural stability during transportation and operation.

[0047] Existing heat pumps generally include a compressor, evaporator, condenser, and expansion valve. In this embodiment, such as... Figure 3As shown, the heat pump single module 2 features a double-layered arrangement of the condenser and evaporator. The heat pump single module 2 also includes a mounting bracket 24, which is arranged vertically in a double-layered manner. The condenser is installed on the upper layer of the mounting bracket 24, and the evaporator is installed on the lower layer. External water branch pipes are pre-installed for heat source recovery and heating connections. This design facilitates the water circuit layout and installation when the heat pump single module 2 is installed with the overall frame. The remaining components can be arranged according to space requirements, and the connection method is consistent with existing technologies.

[0048] Multiple lifting lugs 25 are connected to the top of the mounting frame 24 for in-plant lifting. A forklift mounting position is also provided at the bottom of the mounting frame 24 for forklift transport. A T-shaped fixing block 21 is connected to the bottom beam 241 of the mounting frame 24.

[0049] Assembly process in this embodiment:

[0050] The heat pump module 2 is assembled offline. After assembly, an external water branch pipe interface is reserved. The water interface is used to realize functions such as heat recovery and heating of external waste heat. After the heat pump module 2 is assembled, it can be placed on the body 1 by hoisting or forklifting. The T-shaped fixing block 21 is slid along the mounting groove to a suitable position. The suitable position is when the through hole of the T-shaped fixing block 21 is aligned with the mounting holes on both sides of the mounting beam 11. The position of the heat pump module 2 is fixed by installing the first bolt 22 and the wing nut 23. Then, the power cabinet 5 and the control cabinet 4 are installed, and connected to each heat pump module 2 through cables to realize the power supply and linkage control of the heat pump module 2. The water main pipe is installed to connect the water branch pipes of each heat pump module 2 into a whole.

[0051] For water source heat pump units with different heating needs, only the outer frame size and the number of individual heat pump modules 2 need to be adjusted; the heat pump module 2 unit only needs to add a smaller control cabinet 4 to achieve independent operation.

[0052] Example 2:

[0053] As shown in the figure, in this embodiment, based on the first embodiment, a rubber shock-absorbing pad 26 needs to be added between the bottom beam 241 and the mounting beam 11 of the mounting frame 24 before installation. The rubber shock-absorbing pad 26 is used to reduce vibration and noise.

[0054] Example 3:

[0055] like Figure 5 , Figure 6 As shown, in this embodiment, based on Embodiment 1 or Embodiment 2, the top of the body 1 includes multiple top plates 12.

[0056] The heat pump unit is arranged in zones according to the heat pump single module 2, control cabinet 4, and power cabinet 5. The top frame of the unit 1 forms multiple installation windows arranged in a matrix. Each zone is equipped with a top plate 12. The top plate 12 is connected to the top frame of the unit 1 through a rotating hinge. A pneumatic rod 13 is installed between the bottom of the top plate 12 and the top frame of the unit 1. The fixed end of the pneumatic rod 13 is connected to the top frame, and the telescopic end of the pneumatic rod 13 is connected to the bottom surface of the top plate 12. The opening and closing of the top plate 12 can be achieved through the pneumatic rod 13.

[0057] Furthermore, a folding handle 14 is installed on the outer surface of the body 1 to facilitate the opening and closing of the hatch. Under the action of the pneumatic rod 13, the top plate 12 can remain stationary at any angle within the design range, making it convenient for maintenance personnel to enter the cabin for operation. The rotating mechanism design reduces the assembly error caused by traditional screw fixing and increases the convenience of production, installation and maintenance.

[0058] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
