Description

Technical Field

[0001] The utility model relates to the technical field of heat pumps, in particular to a water channel component and a heat pump system. Background Art

[0002] The heat pump system includes components such as evaporator, compressor, and heat exchanger. When the heat pump system is in heating mode, the evaporator evaporates the refrigerant into gaseous state to absorb heat. The gaseous refrigerant is compressed by the compressor to become high-temperature and high-pressure gas. The high-temperature and high-pressure refrigerant condenses and releases heat in the heat exchanger. The heat exchanger is provided with a water channel. The heat released by the heat exchanger exchanges heat with the water in the water channel. The water after heat exchange is then output from the output end of the heat exchanger to the user end through the water channel system.

[0003] In existing heat pump systems, dissolved refrigerant microbubbles, air, impurities, etc. often appear in the water pipes at the outlet of the heat exchanger. On the one hand, the refrigerant microbubbles, air, impurities, etc. circulate with the water flow in the water system, affecting the performance of the heat pump system. On the other hand, the refrigerant microbubbles will flow into the user's indoor environment with the water flow, posing a safety hazard to the user. At the same time, bubbles often appear in the water pipes at the inlet end of the heat exchanger. The bubbles will occupy the pipe space, resulting in a reduction in the actual fluid flow area. In addition, the bubbles may generate turbulence and resistance during the flow process, further increasing energy loss, thereby reducing the heat exchange efficiency of the heat exchanger. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a water circuit component, by respectively arranging a water outlet unit and a water inlet unit at the water outlet and water inlet ends of the heat exchanger, and fixing and integrating the water outlet unit and the water inlet unit at the same time through a fixed structure, so as to improve the stability of the pipelines at the water outlet and water inlet ends of the heat exchanger, avoid pipeline damage caused by pipeline instability, and cause air and impurities to enter the pipeline. At the same time, a microbubble exhaust valve is arranged in the water outlet unit to timely discharge refrigerant microbubbles, air and other impurities in the pipeline, thereby improving the heat exchange rate of the system and ensuring user safety.

[0005] Another object of the utility model is to provide a heat pump system, which fixes and integrates a water outlet unit and a water inlet unit at the same time through a fixed structure to improve the stability of the pipelines at the water outlet and water inlet ends of the heat exchanger, avoid pipeline damage caused by pipeline instability, and cause air and impurities to enter the pipeline.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0050] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] In the heat pump system, the refrigerant system and the water system are two independent closed flow circulation systems. Generally, the refrigerant will not mix into the water. However, when the refrigerant pipe and the water pipe inside the heat exchanger are damaged, the refrigerant will leak into the water pipe and be output from the output end of the heat exchanger to the outside of the water system, posing a safety hazard to the user. At the same time, if the water pipe connecting the water inlet and outlet of the heat exchanger is damaged, the external air or impurities will enter the water pipe and enter the heat exchanger directly or through the water circulation system with the water flow, thereby affecting the heat exchange efficiency of the heat exchanger. In the past, technicians mainly focused on the design and performance improvement of the internal pipes of the heat exchanger, but often ignored the stability of the water pipes connected to the outside of the heat exchanger, as well as the lack of an effective water design for dealing with the dissolved refrigerant microbubbles, gases and impurities in the water pipes and monitoring the pressure, flow and other parameters in the water.

[0052] Based on this, the utility model provides a water circuit component, which improves the stability of the pipelines at the water outlet and water inlet ends of the heat exchanger by respectively arranging a water outlet unit and a water inlet unit at the water outlet and water inlet ends of the heat exchanger, and fixes and integrates the water outlet unit and the water inlet unit at the same time through a fixed structure, so as to avoid pipeline damage caused by pipeline instability, resulting in air and impurities entering the pipeline. At the same time, a microbubble exhaust valve is arranged in the water outlet unit to timely discharge refrigerant microbubbles, air and other impurities in the pipeline, thereby improving the heat exchange rate of the system and ensuring user safety.

[0053] Please also see Figures 1 to 3 The water circuit assembly provided in the embodiment of the present application relates to a heat exchanger 1, which is fixed on a base 2. The water circuit assembly includes a water outlet unit 10, a water inlet unit 20 and a fixed structure 30. The water outlet unit 10 is provided with a water outlet pipe 11 and a microbubble exhaust valve 12. A first main flow channel 11a is provided inside the water outlet pipe 11. The initial end of the flow path of the first main flow channel 11a is connected to the water outlet end of the heat exchanger 1 to output the water flow after heat exchange with the heat exchanger 1. The microbubble exhaust valve 12 is fixed on the pipeline of the water outlet pipe 11. A water flow channel 121 and an exhaust channel 122 are provided inside the microbubble exhaust valve 12. The water flow channel 121 is connected to the first main flow channel 11a, and the exhaust channel 122 is connected to the water flow channel 121. The water inlet unit 20 is provided with a water inlet pipe 21, and one end of the water inlet pipe 21 is connected to the water inlet end of the heat exchanger 1. The fixing structure 30 is fixed on the base 2 , and the water outlet pipe 11 and the water inlet pipe 21 are both fixedly connected to the fixing structure 30 to ensure the stability of the water outlet unit 10 and the water inlet unit 20 .

[0054] Specifically, the water outlet pipe 11 includes a first water outlet pipe 111 and a second water outlet pipe 112, and a first valve port 1211 and a second valve port 1212 are provided at both ends of the water flow channel 121. One end of the first water outlet pipe 111 is conductively connected to the water outlet end of the heat exchanger 1, and the other end is conductively connected to the first valve port 1211. One end of the second water outlet pipe 112 is conductively connected to the second valve port 1212, and the other end extends to the end of the flow path. In this embodiment, both ends of the first water outlet pipe 111 and the second water outlet pipe 112 are provided with external threads, the first valve port 1211 and the second valve port 1212 are provided with internal threads, and the first water outlet pipe 111 and the second water outlet pipe 112 are respectively connected to the first valve port 1211 and the second valve port 1212 by threads. On the flow path of the water flow channel 121 of the microbubble exhaust valve 12, a filtering structure (not shown) for filtering refrigerant microbubbles, air and other impurities is provided. The water flows into the water flow channel 121 from the first valve port 1211. The filtering structure filters the refrigerant microbubbles, air and other impurities in the water. The filtered water flows out from the second valve port 1212 to the user end, and the filtered refrigerant microbubbles, air and other impurities enter the exhaust channel 122. The gaseous substances are discharged from the exhaust channel 122, while the solid substances are accumulated in the exhaust channel 122. When a certain amount is accumulated, the microbubble exhaust valve 12 can be removed for removal. The air, gaseous refrigerant and other impurities in the water flowing out of the water outlet of the heat exchanger 1 can be discharged through the microbubble exhaust valve 12. At the same time, the first water outlet pipe 111 and the second water outlet pipe 112 are detachably connected to the microbubble exhaust valve 12. When one of the water pipes is damaged, only the damaged water pipe needs to be replaced without replacing the entire water outlet pipe 11, thereby saving user costs.

[0055] In another embodiment, only one valve port is provided in the water flow channel 121. In this case, an interface is provided on the water outlet pipe 11. The valve port of the water flow channel 121 is conductively connected to the interface on the water outlet pipe 11. Water flowing out of the heat exchanger 1 enters the water flow channel 121 from the valve port for exhaust and filtration treatment, and the treated water flows out from the same valve port.

[0056] See also Figure 4In order to facilitate the maintenance of the microbubble exhaust valve 12, as a further embodiment, the water outlet unit 10 is provided with two first stop valves 13, the first water outlet pipe 111 is connected to the first valve port 1211 through one of the first stop valves 13, and the second water outlet pipe 112 is connected to the second valve port 1212 through another first stop valve 13. Specifically, the first stop valve 13 is a multi-way stop valve, one of the through pipes of the first stop valve 13 connected to the first water outlet pipe 111 is connected to the first water outlet pipe 111, wherein another through pipe is connected to the first valve port 1211, and one of the through pipes of the first stop valve 13 connected to the second water outlet pipe 112 is connected to the second water outlet pipe 112, wherein another through pipe is connected to the second valve port 1212. When the switch of the first stop valve 13 is in the open state, the water flow can smoothly flow from the first stop valve 13 on one side of the first water outlet pipe 111 through the microbubble exhaust valve 12, and then flow out from the first stop valve 13 on one side of the second water outlet pipe 112. When the microbubble exhaust valve 12 needs to be repaired, the first stop valves 13 on both sides can be closed, and the water flow is blocked in the first water outlet pipe 111 and the second water outlet pipe 112. At this time, the microbubble exhaust valve 12 can be easily removed to prevent the residual water on one side of the first water outlet pipe 111 and the second water outlet pipe 112 from flowing to the outside and causing water accumulation on the outside.

[0057] In the water system, the water flow delivered to the user end cannot be too large or too small. A large water flow will produce a large water pressure, which is easy to damage the user's water equipment. A small water flow cannot provide enough water, which makes some equipment prone to "dry burning". Therefore, the water flow out of the heat exchanger 1 needs to be controlled within an appropriate range. In this embodiment, in order to facilitate the user to monitor the water flow in the water outlet pipe 11 at any time, the water outlet unit 10 is provided with a plurality of flow alarms 14. Specifically, a plurality of first connection ports 14a are provided on the outer wall of the water outlet pipe 11, and a plurality of first channels 14b are provided inside the water outlet pipe 11. The first connection port 14a is connected to the first main channel 11a through the first channel 14b, and one end of the flow alarm 14 is inserted and fixed in the first connection port 14a. Further, during long-term use, when the flow alarm 14 fails, it needs to be removed for maintenance or replacement. In the past, when the flow alarm 14 was repaired, the entire heat pump system and the water system needed to be shut down, which seriously affected the user's use. In a further embodiment, the water outlet unit 10 is provided with a second stop valve 15, and one end of the flow alarm 14 is connected to the first connection port 14a through the second stop valve 15. Specifically, the second stop valve 15 is a multi-way stop valve, wherein one through pipe is connected to the first connection port 14a, and another through pipe is connected to the flow alarm 14. When the flow alarm 14 is in working state, the flow alarm 14 passes through the channel in the second stop valve 15 and is connected to the first connection port 14a; when the flow alarm 14 has a problem and needs to be repaired or replaced, the second stop valve 15 is closed, and then the flow alarm 14 is taken out from the channel of the second stop valve 15, so as to prevent the water in the water inlet pipe 11 from being ejected from the first connection port 14a. Among them, the flow alarm 14 is a flow switch or other alarm device for monitoring flow. Correspondingly, the number of the first connection ports 14a matches the number of the set flow alarms 14.

[0058] Please also see Figure 1 , Figure 5 and Figure 6 , a second main flow channel 21a is provided inside the water inlet pipe 21, the flow channel end of the second main flow channel 21a is conductively connected to the water inlet end of the heat exchanger 1, and is fixed to the fixed structure 30. A plurality of pressure alarms 22 are provided on the water inlet pipe 21. Specifically, a plurality of second connection ports 22a are provided on the outer wall of the water inlet pipe 21, and a plurality of second channels 22b are provided inside the water inlet pipe 21. The second connection ports 22a are conductively connected to the second main flow channel 21a through the second channels 22b. One end of the pressure alarm 22 is inserted into and fixedly connected to the second connection port 22a, so as to monitor the water flow pressure of the water inlet pipe 21 at any time.

[0059] See also Figure 7In order to facilitate the maintenance of the pressure alarm 22, in a further embodiment, the water inlet unit 20 is provided with a third stop valve 23, and one end of the pressure alarm 22 is connected to the second connection port 22a through the third stop valve 23. Specifically, the third stop valve 23 is a multi-way stop valve, one of which is connected to the second connection port 22a, and another of which is connected to the pressure alarm 22. When the pressure alarm 22 is in a working state, the pressure alarm 22 passes through the channel in the third stop valve 23 and is connected to the second connection port 22a; when the pressure alarm 22 has a problem and needs to be repaired, the third stop valve 23 is closed, and then the pressure alarm 22 is taken out from the channel of the third stop valve 23, which can prevent the water in the water inlet pipe 21 from being ejected from the second connection port 22a. Among them, the pressure alarm 22 is a safety valve or other alarm device for monitoring pressure. Correspondingly, the number of the second connection ports 22a matches the number of the set pressure alarms 22.

[0060] It is understandable that, since the outlet pipe 11 and the inlet pipe 21 of the same water system are connected, the pressure alarm 22 and the third stop valve 23 can be set in the inlet pipe 21, the outlet pipe 11, or both. Similarly, when set on the outlet pipe 11, it is necessary to open a plurality of second connection ports 22a on the outlet pipe 11, set a plurality of second channels 22b inside the outlet pipe 11, the second channels 22b are connected to the first main channel 11a, and the pressure alarm 22 is connected to the second connection port 22a through the third stop valve 23.

[0061] The water inlet unit 20 is provided with a plurality of exhaust valves 24. Specifically, a plurality of third connection ports 24a are provided on the outer wall of the water inlet pipe 21, a plurality of third channels 24b are provided inside the water inlet pipe 21, the third connection port 24a is communicated with the second main channel 21a through the third channels 24b, one end of the exhaust valve 24 is inserted into and fixedly connected to the third connection port 24a, and is used to discharge bubbles in the water flowing through the water inlet pipe 21. In order to facilitate the maintenance of the exhaust valve 24, in a further embodiment, the water inlet unit 20 is provided with a fourth stop valve 25, one end of the exhaust valve 24 is connected to the third connection port 24a through the fourth stop valve 24. Specifically, the fourth stop valve 25 is a multi-way stop valve, one of which is connected to the third connection port 24a, and another of which is connected to the exhaust valve 24. When the exhaust valve 24 is in working state, the exhaust valve 24 passes through the channel in the fourth stop valve 25 and is connected to the third connection port 24a to exhaust the water flowing through; when the exhaust valve 24 has a problem and needs to be repaired, the fourth stop valve 25 is closed, and then the exhaust valve 24 is taken out from the channel of the fourth stop valve 25, so as to prevent the water in the water inlet pipe 21 from being ejected from the third connection port 24a. The exhaust valve 24 can also be a microbubble exhaust valve. Correspondingly, the number of the third connection ports 24a matches the number of the exhaust valves 24 provided.

[0062] Please also see Figure 1 and Figure 8 The fixing structure 30 includes a fixing member 31 and at least two connecting members 32. The fixing member 31 is fixed to the base 2, one end of the connecting member 32 is fixed to the fixing member 31, and the other end is provided with a clamping hole 32a, and the outlet pipe 11 or the inlet pipe 21 is fixed to the clamping hole 32a. In this embodiment, the connecting member 232 is fixed to the fixing member 31 by screws, and there are two connecting members 32, one of which is fixed to the outlet pipe 11, and the end of the flow path of the outlet pipe 11 passes through the clamping hole 32a and is then connected to other equipment pipes in the water system, and the other connecting member 32 is fixed to the inlet pipe 21, and the initial end of the flow path of the inlet pipe 21 passes through the clamping hole 32a. In order to facilitate the adjustment of the installation error of the water pipe and avoid the situation that the water pipe has different degrees of deviation during the actual installation process, which leads to the inability to assemble, the fixing member 31 is provided with a plurality of first mounting holes 311 arranged in a matrix, and the connecting member 32 is provided with a plurality of second mounting holes 321, and the plurality of second mounting holes 321 include transverse and longitudinal elliptical holes. In the installed state, at least one first mounting hole 311 is opposite to at least one second mounting hole 321, and then the fixing member 31 and the connecting member 32 are fixedly connected by screws. During installation, the first mounting holes 311 and the second mounting holes 321 at different positions can be selected according to the actual positions of the outlet pipe 11 and the inlet pipe 21, so that the installation is more convenient and flexible.

[0063] It is understandable that in order to make the water outlet unit 10 and the water inlet unit 20 more firmly fixed to the fixing structure 30 , more than two connecting members 32 may be used to fix the water outlet pipe 11 and the water inlet pipe 21 to the fixing member 31 .

[0064] In order to process and monitor the water in the pipelines of the water outlet unit 10 and the water inlet unit 20, as mentioned above, it is necessary to install multiple water treatment devices and monitoring devices on the pipelines, which will lengthen the pipeline strokes of the water outlet unit 10 and the water inlet unit 20. The fixed structure 30 simultaneously fixes and integrates the water outlet pipe 11 and the water inlet pipe 21, which can simultaneously solve the problem that the water outlet pipe 11 and the water inlet pipe 21 are not firm due to the lengthened pipeline stroke. The integrated water outlet unit 10 and the water inlet unit 20 are more stable and beautiful, so that while ensuring the safety of users and improving the heat exchange efficiency of the system, the stability of the entire system can be improved, and it can be truly safe and reliable.

[0065] See also Fig. 9Furthermore, a first one-way valve 16 is provided at the initial end of the flow path of the water outlet pipe 11, and its conducting direction is the same as the water outlet direction of the water outlet of the heat exchanger 1, so that the water flow can flow out from the water outlet of the heat exchanger 1 to the external water path, and prevent the water flow from the external water path from the water outlet of the heat exchanger 1 to the inside of the heat exchanger 1. At the same time, a second one-way valve 26 is provided at the end of the flow path of the water inlet pipe 21, and its conducting direction is the same as the water inlet direction of the water inlet of the heat exchanger 1, so that the external water flow can enter the inside of the heat exchanger 1 from the water inlet of the heat exchanger 1, and prevent the water flow inside the heat exchanger 1 from flowing out from its water inlet to the external water path.

[0066] An embodiment of the present application also provides a heat pump unit, comprising the above-mentioned water channel assembly.

[0067] Compared with the prior art, the beneficial effects of the technical solution of this application are:

[0068] (1) By respectively arranging a water outlet unit and a water inlet unit at the water outlet and water inlet of the heat exchanger, and fixing and integrating the water outlet unit and the water inlet unit at the same time through a fixed structure, the stability of the pipelines at the water outlet and water inlet of the heat exchanger is improved, and the air and impurities entering the pipeline due to pipeline instability are prevented from being damaged. At the same time, a microbubble exhaust valve is arranged at the water outlet unit to timely discharge the refrigerant microbubbles, air and other impurities in the pipeline, thereby improving the heat exchange rate of the system and ensuring the safety of users;

[0069] (2) The two water outlet pipes and the micro-bubble exhaust valve are detachably connected. When one of the water pipes is damaged, only the damaged water pipe needs to be replaced, saving user costs;

[0070] By arranging stop valves at both ends of the microbubble exhaust valve, when the microbubble exhaust valve needs maintenance, the stop valves on both sides can be closed, and then the microbubble exhaust valve can be removed, which facilitates the maintenance of the microbubble exhaust valve;

[0071] (3) A flow alarm is installed on the water outlet pipe to monitor the water flow at the outlet at any time to avoid damage to the user's water equipment caused by excessive or insufficient water flow;

[0072] An exhaust valve is installed in the water inlet unit to timely discharge the bubbles in the water flow entering the heat exchanger to improve the heat exchange efficiency;

[0073] Install a pressure alarm on the water inlet pipe and / or water outlet pipe to monitor the pressure in the water pipe at any time, so as to understand the gas content in the water pipe and ensure the normal operation of each component;

[0074] (4) The flow alarm, pressure alarm and exhaust valve are all connected to the outlet pipe or the inlet pipe through the stop valve. When the flow alarm, pressure alarm and exhaust valve need to be repaired, there is no need to shut down the entire water system. You only need to close the stop valve to cut off the water flow while removing them.

[0075] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
