Description

Technical Field

[0001] This utility model relates to the field of ground source heat pump control technology, specifically a ground source heat pump multi-variable flow coordinated control device. Background Technology

[0002] A ground source heat pump is a device that uses water circulating in a public pipeline, water drawn from a well, lake, or river, or water circulating in underground coils as a cold (heat) source to produce cold (hot) air or cold (hot) water. It includes a heat exchanger on the user side, a compressor, and a heat exchanger on the heat source side, and has single cooling or cooling and heating functions. Ground source heat pumps are classified into cold and hot air type ground source heat pump units and cold and hot water type ground source heat pump units according to the form of the heat exchanger on the user side.

[0003] For example, the authorization announcement number "CN222352606U" is titled "A Ground Source Heat Pump Variable Flow Co-control Device." This device ensures a dry internal environment, preventing moisture from corroding the internal electronic components and extending its lifespan. Existing ground source heat pump variable flow co-control devices use a pull-out, replaceable dehumidifying filter box to reduce moisture damage in humid environments. However, the working environment of ground source heat pumps is often too humid. The desiccant in a typical dehumidifying filter box has a limited water absorption capacity. Therefore, it quickly becomes saturated, unable to absorb more water and retaining excess moisture inside the filter box. This inability to drain the excess water further degrades the dryness of the environment, reducing the device's lifespan.

[0004] Meanwhile, a relatively large number of dehumidifying filter boxes are installed at the lower end of the ground source heat pump multi-flow coordinated control device. Therefore, during use, staff often need to manually replace and clean the desiccant. This not only involves a large workload but also consumes too much of the staff's time and energy, which is not conducive to the ease of use of the ground source heat pump multi-flow coordinated control device. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of reduced service life and inconvenience of use of existing ground source heat pump multi-flow coordinated control devices, and to propose a ground source heat pump multi-flow coordinated control device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a ground source heat pump variable flow coordinated control device, including a frame, partitions and a storage tank. Multiple partitions are fixedly installed on the inner side of the frame, and the storage tank is fixedly installed on the top of the partitions. The storage tank is equipped with an automatic unloading and dehumidification structure. A desiccant replacement structure is provided on one side of the frame, and a base is fixedly installed at the bottom of the frame.

[0008] Preferably, the automatic unloading dehumidification structure includes a dehumidification box and a drain tank. The dehumidification box is fixedly installed inside the storage box. A water suction hole is fixedly opened at the top of the dehumidification box. A drainage channel is fixedly connected to the bottom of the dehumidification box. A mesh is fixedly installed at the top of the drainage channel. A desiccant is movably placed above the mesh. The drain tank is fixedly installed inside the bottom of the frame. A drain pipe is fixedly connected to one side of the drain tank. A drain pump is fixedly installed on the outside of the drain pipe.

[0009] Preferably, the convenient desiccant replacement structure includes a drying chamber and an inclined tube. The drying chamber is fixedly installed on one side of the outer wall of the frame. An inclined tube is fixedly connected to the lower end of the drying chamber. A solenoid valve is fixedly installed on the inner side of the inclined tube. A docking flange is fixedly connected to the lower end of the inclined tube. The other end of the docking flange is fixedly connected to the outer wall of the dehumidification chamber.

[0010] Preferably, the drying chamber is provided with a desiccant storage structure above it. The desiccant storage structure includes an isolation layer and a top pipe. The top pipe is fixedly installed on the top of the drying chamber. A sealing cap is threaded to the top of the top pipe. A sealing tube is fixedly sleeved on the outer wall of the top pipe. A discharge pipe is fixedly connected to the bottom of the top pipe. The isolation layer is fixedly connected to the inner wall of the drying chamber.

[0011] Preferably, the outer wall of the storage box is rotatably connected to a closed door via a hinge.

[0012] Preferably, a variable flow rate coordinated control device body is fixedly installed on one side of the inside of the storage box, and both the variable flow rate coordinated control device body and the dehumidification box are arranged in the internal space of the storage box.

[0013] The present invention proposes a ground source heat pump variable flow coordinated control device, which has the following advantages: water vapor inside the storage tank is drawn into the dehumidification box by the desiccant through the water inlet. The moisture is gradually released and flows down into the drain tank through the lower drainage channel. When the operator connects the power and starts the drain pump, the stored water is pumped into the drain pipe for discharge, reducing the accumulation of moisture and humidity. The treatment is more timely and efficient. Moisture is less likely to remain in the same space as the ground source heat pump variable flow coordinated control device for a long time, reducing the corrosive effect on the ground source heat pump variable flow coordinated control device and improving the service life of the ground source heat pump variable flow coordinated control device.

[0014] The drying chamber is a sealed tank made of stainless steel. The inclined pipe can be connected to the external pipe of the dehumidification chamber inside the storage tank via a connecting flange. A large amount of desiccant can be filled into the drying chamber by the staff at one time. After the desiccant inside the dehumidification chamber melts and is discharged, the power is connected and the solenoid valve is activated. The solenoid valve will open the inclined pipe to send some desiccant into the dehumidification chamber. Each replacement and replenishment of desiccant is more time-saving and labor-saving, improving the ease of use of the ground source heat pump multi-flow coordinated control device.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] Example 1:

[0024] Please see Figure 1-6In this embodiment, a ground source heat pump variable flow coordinated control device includes a frame 1, partitions 2, and a storage tank 3. Multiple partitions 2 are fixedly installed inside the frame 1, and the storage tank 3 is fixedly installed on the top of the partitions 2. The partitions 2 divide the frame 1 into multiple spaces. The storage tank 3 is placed inside one of these spaces and fixedly secured. The storage tank 3 has an automatic unloading dehumidification structure 5 inside. A desiccant convenient replacement structure 6 is provided on one side of the frame 1. A base 4 is fixedly installed at the bottom of the frame 1. The automatic unloading dehumidification structure 5 includes a dehumidification box 51 and a drain tank 56. The dehumidification box 51 is fixedly installed...

[0025] Inside the storage box 3, the dehumidification box 51 and the multi-flow coordinated control device body 9 are both located inside the storage box 3. The top of the dehumidification box 51 is fixedly provided with a water suction hole 52, which is set upward. Water vapor inside the storage box 3 will be drawn into the dehumidification box 51 by the desiccant 55 along the water suction hole 52. The lower end of the dehumidification box 51 is fixedly connected with a drainage channel 54. After the water absorbed by the desiccant 55 accumulates to a certain extent, it will soak and melt the desiccant 55.

[0026] In this way, the moisture is gradually released and flows down into the drain tank 56 through the lower drainage channel 54. A mesh 53 is fixedly installed at the top of the drainage channel 54. The mesh 53 is made of stainless steel metal mesh plate. The mesh size of the mesh 53 is smaller than the diameter of the desiccant 55, so the desiccant 55 can be intercepted and will not fall directly into the drain tank 56 below. The desiccant 55 is movable above the mesh 53. The desiccant 55 is made of calcium chloride particles. It absorbs moisture in the air through chemical adsorption. When calcium chloride comes into contact with moisture in the air, it forms hydrated calcium chloride, which locks in the moisture and turns it into a liquid.

[0027] The drain tank 56 is fixedly installed on the inner side of the bottom end of the frame 1. A drain pipe 58 is fixedly connected to one side of the drain tank 56. A drain pump 57 is fixedly installed on the outside of the drain pipe 58. The water is inside the drain tank 56. When the operator connects the power and turns on the drain pump 57, the stored water is pumped into the drain pipe 58 and discharged. This can remove the desiccant and the water absorbed by the desiccant as quickly as possible, reducing the accumulation of moisture and humidity.

[0028] Both the dehumidification box 51 and the variable flow rate co-control device body 9 are located inside the storage box 3, with the water intake hole 52 facing upwards. Moisture inside the storage box 3 is drawn into the dehumidification box 51 by the desiccant 55 through the water intake hole 52. After the moisture absorbed by the desiccant 55 accumulates to a certain level, it melts the desiccant 55, causing it to gradually precipitate and flow downwards into the drain tank 56 through the lower drainage channel 54. Inside the drain tank 56, the water is pumped to the drain pipe 58 by the operator after connecting the power supply and starting the drain pump 57. This maximizes the rapid removal of the desiccant and the moisture it absorbs, reducing moisture and humidity buildup. This method provides a simpler and more timely way to handle moisture in the space of the variable flow rate co-control device body 9, preventing moisture from remaining in the same space for extended periods and reducing the corrosive effects on the device, thus extending its service life.

[0029] The desiccant easy-to-replace structure 6 includes a drying chamber 61 and an inclined tube 62. The drying chamber 61 is fixedly installed on one side of the outer wall of the frame 1. The drying chamber 61 is a closed tank made of stainless steel. The lower end of the drying chamber 61 is fixedly connected to the inclined tube 62. The inclined tube 62 can be connected to the external pipe of the dehumidification box 51 inside the storage box 3 through the docking flange 64. A solenoid valve 63 is fixedly installed on the inner side of the inclined tube 62. A large amount of desiccant 55 can be filled into the drying chamber 61 by the operator at one time.

[0030] The lower end of the inclined tube 62 is fixedly connected to the docking flange 64. When the desiccant 55 inside the dehumidification box 51 melts and is discharged, the power supply is connected to start the solenoid valve 63. The solenoid valve 63 will open the inclined tube 62 to send some desiccant 55 into the dehumidification box 51. Each time the desiccant is replaced and replenished, it is more time-saving and labor-saving. The other end of the docking flange 64 is fixedly connected to the outer wall of the dehumidification box 51.

[0031] The drying chamber 61 is a sealed tank made of stainless steel. The inclined pipe 62 can be connected to the external pipe of the dehumidification chamber 51 inside the storage box 3 via the docking flange 64. A large amount of desiccant 55 can be filled into the drying chamber 61 by the staff at one time. After the desiccant 55 inside the dehumidification chamber 51 melts and is discharged, the power supply is connected to start the solenoid valve 63. The solenoid valve 63 will open the inclined pipe 62 to send some desiccant 55 into the dehumidification chamber 51. Each replacement and replenishment of desiccant is more time-saving and labor-saving, improving the ease of use of the ground source heat pump multi-flow coordinated control device.

[0032] The drying chamber 61 is provided with a desiccant storage structure 7 above it. The desiccant storage structure 7 includes an isolation layer 71 and a top tube 73. The top tube 73 is fixedly installed on the top of the drying chamber 61. The top tube 73 can be closed by rotating and tightening the sealing cover 72 to reduce the amount of water vapor entering the drying chamber 61 and damaging the stored desiccant 55. The top of the top tube 73 is threadedly connected to the sealing cover 72.

[0033] A sealing pipe 74 is fixedly sleeved on the outer wall of the jacking pipe 73. The sealing platform 74 is made of rubber material and is sleeved at the connection between the jacking pipe 73 and the drying box 61. This can further improve the sealing effect and reduce the premature failure of the desiccant due to water vapor erosion. A feeding pipe 75 is fixedly connected to the bottom of the jacking pipe 73. Finally, the operator can unscrew the opening cover 72 and pour the desiccant 55 into the feeding pipe 75 along the jacking pipe 73 for replenishment. The isolation layer 71 is fixedly connected to the inner wall of the drying box 61. The isolation layer 71 is made of ceramic material and has a high drying and waterproof performance.

[0034] Working principle:

[0035] First, the ground source heat pump multi-flow coordinated control device is transported to the designated location and installed. The ground source heat pump is controlled by the control device body 9. The ground source heat pump can use water circulating in the public pipeline, water drawn from wells, lakes or rivers, or water circulating in underground coils as a cold (heat) source to produce cold (hot) air or cold (hot) water.

[0036] Internal dehumidification protection structure of the ground source heat pump multi-flow coordinated control device:

[0037] The dehumidification box 51 and the multi-flow coordinated control device body 9 are both located inside the storage box 3. The water suction hole 52 is set upward. The water vapor inside the storage box 3 will be sucked into the dehumidification box 51 by the desiccant 55 along the water suction hole 52. After the water absorbed by the desiccant 55 accumulates to a certain extent, it will soak and melt the desiccant 55. In this way, the water is gradually released and flows down into the drain tank 56 along the lower drainage channel 54. The water is in the drain tank 56. When the operator connects the power and turns on the drain pump 57, the stored water source is pumped into the drain pipe 58 and discharged. In this way, the desiccant and the water absorbed by the desiccant can be discharged as quickly as possible, reducing the accumulation of moisture and humidity.

[0038] Quick-change desiccant structure for ground source heat pump multi-flow coordinated control device:

[0039] The drying chamber 61 is a closed tank made of stainless steel. The inclined pipe 62 can be connected to the external pipe of the dehumidification chamber 51 inside the storage box 3 via the docking flange 64. A large amount of desiccant 55 can be filled into the drying chamber 61 by the staff at one time. After the desiccant 55 inside the dehumidification chamber 51 melts and is discharged, the power is connected to start the solenoid valve 63. The solenoid valve 63 will open the inclined pipe 62 to send some desiccant 55 into the dehumidification chamber 51. Each time the desiccant is replaced and replenished, it is more time-saving and labor-saving.

[0040] Desiccant replenishment and protection structure of the ground source heat pump multi-flow coordinated control device:

[0041] The jacking pipe 73 can be closed by rotating and tightening the sealing cap 72, reducing the amount of moisture entering the drying chamber 61 and damaging the stored desiccant 55. The sealing sleeve 74 is made of rubber and fits under the jacking pipe 73 at the connection with the drying chamber 61, which can further improve the sealing effect and reduce the premature failure of the desiccant due to moisture erosion. Finally, the operator can unscrew the sealing cap 72 to pour desiccant 55 into the feed pipe 75 along the jacking pipe 73 for replenishment. The isolation layer 71 is made of ceramic material and has high drying and waterproof performance.

[0042] Example 2:

[0043] Please see Figure 1-6 In this embodiment, a ground source heat pump variable flow coordinated control device also includes a closed door 8 that is rotatably connected to the outer wall of the storage tank 3 via a hinge. The closed door 8 is made of stainless steel and can be opened from the outside of the storage tank 3 along the hinge. The variable flow coordinated control device body 9 is fixedly installed on one side of the inside of the storage tank 3. The variable flow coordinated control device body 9 is a mature technology at present. The variable flow coordinated control device body 9 can control the ground source heat pump to work. The variable flow coordinated control device body 9 and the dehumidification box 51 are both arranged in the internal space of the storage tank 3.

[0044] Working principle:

[0045] The closed door 8 is made of stainless steel and can be opened from the outside of the storage tank 3 along the hinge. The variable flow coordinated control device body 9 is fixedly installed on one side of the inside of the storage tank 3. The variable flow coordinated control device body 9 is a mature technology at present and can control the ground source heat pump to work.
