Description

Technical Field

[0001] This utility model belongs to the field of heat pump energy supply technology, specifically relating to an energy storage type water source heat pump energy supply system. Background Technology

[0002] With the mature application of water source heat pump technology in building heating and cooling systems, centralized heating is gaining popularity among homeowners. The centralized heating cycle typically lasts about three months in both summer and winter, which is relatively long. Generally, centralized heating systems provide energy at a relatively constant temperature. However, during the harsh winter and hot summer periods, the system needs to provide higher energy capacity to withstand these extreme conditions. Conversely, during the earlier and later stages of the heating cycle, when the weather is less extreme, the system can be adjusted to provide a more comfortable, constant temperature. Based on these considerations, further research and development are needed on the energy supply system and methods of heat pump systems to improve their applicability. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this utility model is to provide an energy storage type water source heat pump power supply system.

[0004] The technical solution for realizing this utility model is as follows: The energy storage type water source heat pump power supply system includes an energy storage box and a water source heat pump unit. The energy storage box is divided into independent first buffer chamber, first energy storage chamber, intermediate coupling chamber, second energy storage chamber and second buffer chamber from left to right. A water supply pipeline connects the water source inlet of the water source unit to the energy storage tank. The water supply pipeline is connected to the first energy storage chamber, the intermediate coupling chamber, and the second energy storage chamber, respectively, and water is drawn from one of the three chambers; a first water-passing plate assembly is arranged between the first buffer chamber and the first energy storage chamber, and a second water-passing plate assembly is arranged between the second energy storage chamber and the second buffer chamber; water-passing hole groups are distributed on the first water-passing plate assembly and the second water-passing plate assembly respectively; The first energy storage chamber stores low-temperature water, the second energy storage chamber stores high-temperature water, and the intermediate coupling chamber stores mixed water from the first and second energy storage chambers; A return water pipe connects the water source outlet of the water source heat pump unit to the energy storage tank. The return water pipeline is connected to the first buffer chamber and the second buffer chamber. The return water pipeline is equipped with a first heat exchange device for exchanging heat with the water flowing into the first buffer chamber and a second heat exchange device for exchanging heat with the water flowing into the second buffer chamber.

[0005] The first energy storage chamber stores low-temperature water, and the second energy storage chamber stores high-temperature water. The water temperature is relative; that is, the water temperature in the second energy storage chamber is higher than that in the first energy storage chamber. The water temperature in the first energy storage chamber can meet the water source inlet temperature requirements of the water source heat pump unit in cooling mode, and the water temperature in the second energy storage chamber can meet the water source inlet temperature requirements of the water source heat pump unit in heating mode.

[0006] The water supply pipeline includes the main water supply pipeline, the first water pump, the first water supply pipeline, the second water supply pipeline, and the third water supply pipeline; The main water supply pipeline is connected to the first, second, and third water supply pipelines via a four-way connector. The first water pump is installed on the main water supply pipeline. The first water supply pipeline is connected to the bottom of the first energy storage chamber. The second water supply pipeline is connected to the bottom of the intermediate coupling chamber. The third water supply pipeline is connected to the bottom of the second energy storage chamber. A first water supply electric valve is installed on the first water supply pipeline, a second water supply electric valve is installed on the second water supply pipeline, and a third water supply electric valve is installed on the third water supply pipeline. The first, second, and third water supply electric valves can be opened selectively.

[0007] The return water pipeline includes a main return water pipeline, a first return water pipeline connected to the main return water pipeline via a tee joint, and a second return water pipeline. A first return water electric valve is installed on the first return water pipeline, and a second return water electric valve is installed on the second return water pipeline. The first heat exchange device is arranged on the first return water pipe, and the second heat exchange device is arranged on the second return water pipe; The first heat exchange device is a cooling tower; The second heat exchange device includes a plate heat exchanger and a heating unit. The primary side of the plate heat exchanger is connected to the heating unit, and the secondary side of the plate heat exchanger is connected to the second return water pipe.

[0008] A first bypass pipe is connected to both ends of the first return water pipe, and a first bypass electric valve is installed on the first bypass pipe; The plate heat exchanger has a second bypass pipe connected to both ends of the secondary side, and a second bypass electric valve is installed on the second bypass pipe.

[0009] The intermediate coupling chamber is connected to a coupling pipe, which is connected to a first connecting pipe and a second connecting pipe via a tee joint. The first connecting pipe is connected to the bottom of the first energy storage chamber, and the second connecting pipe is connected to the bottom of the second energy storage chamber. A first flow control valve is installed on the first connecting pipe, a second flow control valve is installed on the second connecting pipe, and a second water pump is installed on the coupling pipe. Temperature sensors are installed in the intermediate coupling chambers, and the temperature sensors are electrically connected to the first flow control valve and the second flow control valve.

[0010] Thermometers and level gauges for detecting the water temperature and liquid level are respectively installed in the first buffer chamber, the first energy storage chamber, the second energy storage chamber, and the second buffer chamber.

[0011] The first and second energy storage chambers are each equipped with pressure relief pipes, and pressure relief valves are installed on the pressure relief pipes. Pressure gauges for monitoring pressure are installed in the first and second energy storage chambers.

[0012] By adopting the above technical solution, when water is drawn from the second energy storage chamber, a heating mode is achieved, providing high-temperature water to the water source side of the water source heat pump unit as the water source for heating. The return water of the water source heat pump unit undergoes heat exchange through the first heat exchange device. After the temperature is reduced, it enters the first buffer chamber for buffering and then flows to the first energy storage chamber to achieve the cold storage process.

[0013] When water is drawn from the first energy storage chamber, a cooling mode is achieved, providing cold water to the water source side of the water source heat pump unit as the water source for cooling of the water source heat pump unit. The return water of the water source heat pump unit passes through the second heat exchange device, and after the temperature is raised again, it enters the second buffer chamber for buffering, and then flows to the second energy storage chamber to achieve the heat storage process.

[0014] The aforementioned heating / cooling mode is more suitable for the severe cold and freezing periods of winter and the scorching heat of summer. When water is drawn from the intermediate coupling chamber, the low-temperature water in the first energy storage chamber and the high-temperature water in the second energy storage chamber are coupled together to provide a relatively stable water supply temperature to the water source side of the water source heat pump unit. This provides a relatively constant temperature for heating / cooling during the initial and final stages of the centralized heating / cooling cycle when heating / cooling demand is low. This invention allows for adjustments to the energy supply strategy during centralized heating and cooling periods to better adapt to energy demands and improve the living comfort of residents.

[0016] 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 with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] Please see Figure 1-3 As shown, this energy storage type water source heat pump power supply system is relatively suitable for use in small centralized heating buildings. It includes an energy storage box 1 and a water source heat pump unit 2. The energy storage box 1 is divided into independent first buffer chamber 3, first energy storage chamber 4, intermediate coupling chamber 5, second energy storage chamber 6, and second buffer chamber 7 from left to right. The adjacent chambers are separated by vertically arranged stainless steel partitions. The energy storage box 1 is made of stainless steel and has a polyurethane insulation layer on the outside.

[0018] A heat insulation cavity 8 is formed between the first energy storage chamber 4 and the intermediate coupling chamber 5, and between the second energy storage chamber 6 and the intermediate coupling chamber 5. The heat insulation cavity 8 is formed between two vertically arranged stainless steel partitions. The heat insulation cavity 8 is filled with polyurethane material to reduce the heat transfer from the first energy storage chamber 4 to the intermediate coupling chamber 5, and the heat transfer from the second energy storage chamber 6 to the intermediate coupling chamber 5.

[0019] A water supply pipeline connects the water source inlet of the water source unit 2 to the energy storage tank 1, so that the water in the energy storage tank 1 can supply water to the water source side of the water source heat pump unit 2; the water supply pipeline is connected to the first energy storage chamber 4, the intermediate coupling chamber 5 and the second energy storage chamber 6 respectively, and water can be drawn from one of the three chambers; the first energy storage chamber 4 stores low temperature water, the second energy storage chamber 6 stores high temperature water, and the intermediate coupling chamber 5 stores mixed water from the first energy storage chamber 4 and the second energy storage chamber 6.

[0020] The low-temperature water stored in the first energy storage chamber 4 is used by the water source heat pump for cooling during the high-temperature period in summer; the high-temperature water stored in the second energy storage chamber 6 is used by the water source heat pump for heating during the severe cold period in winter; the medium-temperature mixed water in the intermediate coupling chamber 5 provides relatively constant heating / cooling temperature during the initial / final stages of the centralized heating / cooling cycle when heating / cooling demand is low. The terms low-temperature water, medium-temperature water, and high-temperature water are relative, indicating that the temperature of the high-temperature water is higher than that of the medium-temperature water, and the temperature of the medium-temperature water is higher than that of the low-temperature water, all three temperatures falling within the inlet water temperature range of the water source side of the water source heat pump.

[0021] A first water-passing plate assembly 9 is arranged between the first buffer chamber 3 and the first energy storage chamber 4, and a second water-passing plate assembly 10 is arranged between the second energy storage chamber 6 and the second buffer chamber 7. Water-passing hole groups 11 are respectively distributed on the first water-passing plate assembly 9 and the second water-passing plate assembly 10. Through the water-passing hole groups 11 on the corresponding water-passing plate assemblies, the water in the first buffer chamber 3 can flow towards the first energy storage chamber 4, and the water in the second buffer chamber 7 can flow towards the second energy storage chamber 6.

[0022] The specific structure of the first water-passing plate assembly 9 is described below. The structure of the second water-passing assembly is the same as that of the first water-passing plate assembly 9. A rectangular connecting hole 12 is provided at the lower part of the partition between the first buffer chamber 3 and the first energy storage chamber 4 to connect the two chambers. The width of the rectangular connecting hole 12 is slightly smaller than the width of the partition. The first water-passing plate assembly 9 includes two perforated plates 13. Water-passing hole groups 11 are distributed on the perforated plates 13. The water-passing hole groups 11 are multiple rows of circular through holes opened on the perforated plates 13. One perforated plate 13 is fixedly installed in the first buffer chamber 3, and the other perforated plate 13 is fixedly installed in the first energy storage chamber 4.

[0023] The orifice plate has a rectangular portion 14 and an extension portion 15. The rectangular portion 14 extends into the rectangular connecting hole 12, and its outer periphery fits against the inner wall of the rectangular connecting hole 12. A water passage group 11 is formed on the rectangular portion 14. An extension portion 15 with a thickness less than the rectangular portion 14 extends from the outer periphery of the rectangular portion 14 and is welded and fixed to the partition plate. The water passage groups 11 on the two orifice plates are staggered, and the end faces of the two orifice plates within the rectangular connecting hole 12 do not contact each other, i.e., a cavity is formed between the two end faces. The orifice plate structure reduces the possibility of pressure deformation at the rectangular connecting hole 12. At the same time, the multiple channels formed by the water passage groups 11 on the orifice plate facilitate flow between the first buffer chamber 3 and the first energy storage chamber 4, which helps to improve the mixing and equalization of water temperature.

[0024] A return water pipeline connects the water source outlet of the water source heat pump unit 2 to the energy storage tank 1, so that the water source side of the water source heat pump unit 2 can return water. The return water pipeline is connected to the first buffer chamber 3 and the second buffer chamber 7. A first heat exchange device 16 for exchanging heat with the water flowing into the first buffer chamber 3 and a second heat exchange device 17 for exchanging heat with the water flowing into the second buffer chamber 7 are installed on the return water pipeline.

[0025] When storing cold water in the first buffer chamber 3, the return water from the water source side of the water source heat pump unit 2 is cooled by the first heat exchange device 16 and then discharged into the first buffer chamber 3. When storing heat water in the second buffer chamber 7, the return water from the water source side of the water source heat pump unit 2 is heated by the second heat exchange device 17 and then discharged into the second buffer chamber 7. The first heat exchange device 16 can be a cooling tower, and the second heat exchange device 17 is a plate heat exchanger that exchanges heat with the hot water in the solar water tank. For example, the hot water in the solar water tank passes through the primary side of the plate heat exchanger, and the return water from the water source side of the water source heat pump unit 2 passes through the secondary side of the plate heat exchanger, thereby raising the temperature of the return water from the water source side of the water source heat pump unit 2.

[0026] In one embodiment, the water supply pipeline includes a main water supply pipeline 18, a first water pump 19, a first water supply pipeline 20, a second water supply pipeline 21, and a third water supply pipeline 22. The main water supply pipe 18 is connected to the first water supply pipe 20, the second water supply pipe 21, and the third water supply pipe 22 through a four-way connector 23. The first water pump 19 is installed on the main water supply pipe 18. The first water supply pipe 20 is connected to the bottom of the first energy storage chamber 4. The second water supply pipe 21 is connected to the bottom of the intermediate coupling chamber 5. The third water supply pipe 22 is connected to the bottom of the second energy storage chamber 6.

[0027] A first water supply electric valve 24 is installed on the first water supply pipeline 20, a second water supply electric valve 25 is installed on the second water supply pipeline 21, and a third water supply electric valve 26 is installed on the third water supply pipeline 22. One of the three electric valves—first, second, and third—can be opened at any time. Specifically, when water is drawn from the first energy storage chamber 4, the first water supply electric valve 24 is opened and the second and third electric valves are closed; when water is drawn from the second energy storage chamber 6, the third electric valve 26 is opened and the first and second electric valves 24 and 25 are closed; and when water is drawn from the intermediate coupling chamber 5, the second electric valve 25 is opened and the first and third electric valves 24 and 26 are closed.

[0028] The return water pipeline includes a main return water pipe 27, a first return water pipe 29 connected to the main return water pipe 27 via a tee joint 28, and a second return water pipe 30. A first return water electric valve 31 is installed on the first return water pipe 29, and a second return water electric valve 32 is installed on the second return water pipe 30. When the return water from the water source side of the water source heat pump unit 2 is discharged into the first buffer chamber 3, the first return water electric valve 31 is opened and the second return water electric valve 32 is closed. When the return water from the water source side of the water source heat pump unit 2 is discharged into the second buffer chamber 7, the second return water electric valve 32 is opened and the first return water electric valve 31 is closed. A makeup water pipe 46 is connected to the main return water pipe 27, and a makeup water control valve 47 is installed on the makeup water pipe 46 for replenishing water to the energy supply system.

[0029] The first heat exchange device 16 is arranged on the first return water pipe 29 and is used to exchange heat with the return water heading towards the first buffer chamber 3. The second heat exchange device 17 is arranged on the second return water pipe 30 and is used to exchange heat with the return water heading towards the second buffer chamber 7.

[0030] The first heat exchange device 16 is a cooling tower; the second heat exchange device 17 includes a plate heat exchanger and a heating unit. The primary side of the plate heat exchanger is connected to the heating unit, and the secondary side of the plate heat exchanger is connected to the second return water pipe 30. The heating unit here is the solar water tank mentioned above, that is, a water tank used to collect solar water. The water in the water tank can be circulated on the primary side of the plate heat exchanger by adding a circulation pump to exchange heat with the return water on the secondary side of the plate heat exchanger.

[0031] A first bypass pipe 33 is connected to both ends of the first return water heat exchange pipe. A first bypass electric valve 34 is installed on the first bypass pipe 33. When the water source heat pump unit 2 is running in a cold environment, if the return water temperature on the water source side of the water source heat pump (the inlet and return water temperatures are monitored by temperature sensors at both the inlet and outlet ends of the water source side of the water source heat pump unit 2) meets the temperature for entering the first buffer chamber 3, the first bypass electric valve 34 can be opened and the first return water electric valve 31 can be closed, so that the water can directly enter the first buffer chamber 3.

[0032] Similarly, a second bypass pipe 35 is connected to both ends of the secondary side of the plate heat exchanger, and a second bypass electric valve 36 is installed on the second bypass pipe 35. When the water source heat pump unit 2 is running in the cooling mode under hot weather conditions, if the return water temperature on the water source side of the water source heat pump meets the temperature for entering the second buffer chamber 7, the second bypass electric valve 36 can be opened and the second return water electric valve 32 can be closed, allowing the return water to directly enter the second buffer chamber 7.

[0033] A coupling pipe 37 is connected within the intermediate coupling chamber 5. The coupling pipe 37 is connected to a first connecting pipe 38 and a second connecting pipe 39 via a tee connector 28. The first connecting pipe 38 is connected to the bottom of the first energy storage chamber 4, and water from the first energy storage chamber 4 is transported to the intermediate coupling chamber 5 through the first connecting pipe 38. The second connecting pipe 39 is connected to the bottom of the second energy storage chamber 6, and water from the second energy storage chamber 6 is transported to the intermediate coupling chamber 5 through the second connecting pipe 39. A first flow control valve 40 is installed on the first connecting pipe 38 to control the flow rate of water transported from the first energy storage chamber 4 to the intermediate coupling chamber 5. A second flow control valve 41 is installed on the second connecting pipe 39 to control the flow rate of water transported from the second energy storage chamber 6 to the intermediate coupling chamber 5. A second water pump 42 is installed on the coupling pipe 37 to provide power for drawing water from the first energy storage chamber 4 and the second energy storage chamber 6.

[0034] A temperature sensor is installed inside the intermediate coupling chamber 5, and the temperature sensor is electrically connected to the first flow control valve and the second flow control valve. When the temperature sensor detects that the water temperature in the intermediate coupling chamber 5 is lower than the set temperature, it increases the opening degree of the second flow control valve or decreases the opening degree of the first flow control valve to bring the water temperature in the intermediate coupling chamber 5 to the set range. Similarly, when the water temperature in the intermediate coupling chamber 5 is higher than the set temperature, it decreases the opening degree of the second flow control valve or increases the opening degree of the first flow control valve to bring the water temperature in the intermediate coupling chamber 5 to the set range.

[0035] Thermometers and level gauges for detecting the water temperature and liquid level in the first buffer chamber 3, the first energy storage chamber 4, the second energy storage chamber 6, and the second buffer chamber 7 are respectively installed to monitor the temperature and water level in the corresponding chambers.

[0036] The first energy storage chamber 4 and the second energy storage chamber 6 are each equipped with a pressure relief pipe 43. A pressure relief valve 44 is installed on the pressure relief pipe 43. When the pressure in the energy storage chamber exceeds the preset value, the pressure relief valve 43 will automatically open to release the excess pressure. The first energy storage chamber 4 and the second energy storage chamber 6 are equipped with pressure gauges 45 to monitor the pressure in the energy storage chamber.

[0037] Finally, it should be noted that the above embodiments are merely preferred embodiments of the present utility model used to illustrate the technical solutions of the present utility model, and are not intended to limit them, much less limit the patent scope of the present utility model. Although the present 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present utility model. In addition, the direct or indirect application of the technical solutions of the present utility model to other related technical fields is similarly included within the patent protection scope of the present utility model.
