[0056] Other objects and advantages of the present invention will become clear by explaining the preferred embodiments of the present application below.
[0057] First Implementation Method
[0058] Figure 1 An exemplary diagram of an energy comprehensive utilization system 10 according to one embodiment of the present invention is shown.
[0059] like Figure 1As shown, an energy utilization system for swimming pools or other humid locations includes an evaporator 11 for adjusting the temperature and / or humidity inside the swimming pool or other humid location. The following description uses an application in a swimming pool as an example, but it should be clear that this system can also be applied to other similar humid scenarios.
[0060] In summer, swimming pools are hot and humid. This system can cool and dehumidify the hot and humid air inside the swimming pool, and use the heat obtained from the indoor environment of the swimming pool to heat the shower water and pool water, achieving efficient use of energy. Excess heat can be transferred to underground storage through the buried pipe system.
[0061] Specifically, the system includes a first compressor 12, a first heat exchanger 13, and a second heat exchanger 14. The inlet 121 of the first compressor 12 is connected to the outlet 112 of the evaporator 11, the outlet 122 of the first compressor 12 is connected to the inlet 131 of the first heat exchanger 13, the outlet 132 of the first heat exchanger 13 is connected to the inlet 141 of the second heat exchanger 14, and the outlet of the second heat exchanger 14 is connected to the inlet 111 of the evaporator 11.
[0062] The first heat exchanger 13 is connected to the shower equipment 16 and is used to heat the shower water. The second heat exchanger 14 is connected to the swimming pool 17 and is used to heat the water in the swimming pool 17.
[0063] In this embodiment, the temperature of the circulating medium (e.g., R22, R401, etc.) decreases after flowing through the second heat exchanger 14 and exchanging heat with the water in the pool 17. It then flows to the inlet 111 of the evaporator 11, where it exchanges heat with the air in the swimming pool through the indirect wall, thus cooling the indoor air. As the indoor air temperature decreases, its humidity content decreases, for example, from humid and hot air at 28 degrees Celsius with a relative humidity of 80% to dry and cool air at 24 degrees Celsius with a relative humidity of 40%. This improves the comfort experience of people in the swimming pool and also allows the circulating medium to obtain some energy from the air in the swimming pool, thus increasing its temperature.
[0064] The heated circulating medium flows from the evaporator 11 to the first compressor 12, where its temperature is further increased after compression. A portion of the circulating medium flows through the first heat exchanger 13 to heat shower water, and then flows from the first heat exchanger 13 to the second heat exchanger 14 to heat the pool water. Since the heat used for shower water is relatively small, this portion of the circulating medium is sufficient to meet the usage requirements. The remaining circulating medium flows directly to the second heat exchanger 14 to heat the pool water. The temperature of the circulating medium flowing through the second heat exchanger 14 decreases, and it then flows back to the evaporator 11, thus forming a loop.
[0065] To facilitate flow path adjustment, the system also includes a first diverter valve 15, which may have, for example, two switchable flow paths. The first inlet 151 of the first diverter valve 15 is connected to the outlet 112 of the evaporator 11, and the first outlet 152 is connected to the inlet 121 of the first compressor 12. The second inlet 153 of the first diverter valve 15 is connected to the outlet 122 of the first compressor 12, and the second outlet 154 is connected to the inlet 141 of the second heat exchanger 14. In this embodiment, the first inlet 151 and its first outlet 152 of the first diverter valve 15 are in communication; while the second inlet 153 and its second outlet 154 are in communication. By adjusting the first diverter valve 15, the flow path state of the system can be adjusted as needed.
[0066] This system can use the temperature of the indoor air in the swimming pool to heat the shower water and pool water, improving energy efficiency. In addition, the humidity decreases after the indoor air temperature drops, changing from hot and humid air to cool and dry air, thus improving the comfort experience of swimmers.
[0067] Second Implementation Method
[0068] This embodiment is a further improvement on the first embodiment.
[0069] Figure 2 An exemplary schematic diagram of an energy comprehensive utilization system 20 according to another embodiment of the present invention is shown.
[0070] In spring or autumn, the indoor temperature of swimming pools is low, but the indoor humidity is still high, so it is necessary to heat up and dehumidify the indoor air of swimming pools.
[0071] In this embodiment, the circulating medium flowing out of the outlet 142 of the second heat exchanger 14 first enters the inlet 211 of the radiator 21, then flows from the outlet 212 of the radiator 21 to the inlet 111 of the evaporator 11, and finally returns from the outlet 112 of the evaporator 11 to the inlet 121 of the first compressor 12.
[0072] In the above cycle, the circulating medium in radiator 21 first heats the air flowing through it, raising its temperature. After exiting radiator 21, the circulating medium cools and flows into evaporator 11, where it further cools and dehumidifies the air. In other words, the air in the swimming pool first flows through evaporator 11 and is cooled, its humidity decreasing, transforming from humid and cold air to dry and cold air. This dry and cold air then flows through radiator 21 and is heated, further transforming into dry and warm air.
[0073] Therefore, the system of this embodiment can heat and dehumidify the air in the swimming pool, thereby improving the comfort experience of swimmers in cooler seasons such as spring and autumn.
[0074] To achieve the above functions, the system in this embodiment includes valves 22 and 23. Valve 22 is connected in series in a pipeline from the outlet 142 of the second heat exchanger 14 to the inlet 111 of the evaporator 11. One end of pipeline 213 is connected to the pipeline on the inlet side of valve 22, and the other end of pipeline 213 is connected to the inlet 211 of radiator 21. Valve 23 is connected in series on pipeline 213. One end of pipeline 214 is connected to the pipeline on the outlet side of valve 22, and the other end of pipeline 214 is connected to the outlet 212 of radiator 21.
[0075] In this embodiment, when circulating medium needs to flow through radiator 21, valve 22 is closed and valve 23 is opened; when circulating medium does not need to flow through radiator 21, valve 22 is opened and valve 23 is closed. Valves 22 and 23 allow adjustment between the system's cooling / dehumidification mode and heating / dehumidification mode, thus adapting to different indoor temperature and humidity conditions in the swimming pool.
[0076] Third Implementation Method
[0077] In extremely hot summer conditions, such as when the ambient temperature exceeds 40 degrees Celsius, the water temperature in the swimming pool and the room temperature in the swimming hall are both high, making it difficult to use the pool water to cool and dehumidify the indoor air.
[0078] To address the aforementioned technical problems, this embodiment proposes further solutions. Figure 3 This is a system schematic diagram of an energy comprehensive utilization system according to another embodiment of the present invention.
[0079] like Figure 3 As shown, the energy system 30 further includes a third heat exchanger 31 and a ground source heat pump system 32, which are connected by pipelines to form a circulation loop. This embodiment utilizes the characteristic of relatively constant ground temperature. In summer, the circulation loop is used to transfer excess heat from the system to the ground, while in winter, the circulation loop is used to extract heat from the ground into the system.
[0080] The following only describes the differences between this embodiment and the first embodiment. Specifically, for example... Figure 3 As shown, in this embodiment, the circulating medium is divided into three paths after flowing out of the first compressor 12.
[0081] In the first path, the outlet 122 of the first compressor 12 is connected to the inlet 131 of the first heat exchanger 13 via valve 51, for heating shower water. After the circulating medium flows out of the outlet 132 of the first heat exchanger 13, it can be connected to the inlet end of valves 34 and 35, for example.
[0082] In the second path, the outlet 122 of the first compressor 12 is connected to the inlet 141 of the second heat exchanger 14 via a valve 35, for heating pool water. In this embodiment, the opening degree of the valve 35 can be adjusted in real time according to the temperature of the pool water. After the temperature of the pool water reaches the set temperature (e.g., 28 degrees Celsius), the valve 35 can be closed. The outlet 142 of the second heat exchanger 14 is connected to the inlet 111 of the evaporator 11 via a pipeline 36.
[0083] The third route connects the outlet 122 of the first compressor 12 to the inlet 311 of the third heat exchanger 31 via valve 34 and second diverting valve 33, for cooling the circulating medium. The cooled circulating medium then flows from the outlet 312 of the third heat exchanger 31 and pipeline 36 to the inlet 111 of the evaporator 11.
[0084] In this embodiment, even in extremely hot summer conditions where the pool water temperature is too high to serve as a cooling source, the ground can be used as a cooling source to cool the circulating medium of the system, thereby reducing the room temperature and humidity of the swimming pool. Simultaneously, the system 30 utilizes heat extracted from the air to heat the shower water and pool water, achieving optimized energy utilization and significantly reducing energy consumption.
[0085] Fourth Implementation Method
[0086] like Figure 4 As shown, the system 40 of this embodiment includes a solar thermoelectric cogeneration panel 41, which is connected to an inverter 42. The inverter 42 is used to convert direct current (DC) into alternating current (AC). The inverter 42 is electrically connected to a first compressor 12 to supply power to the first compressor 12. In addition, the inverter 42 can also be connected to the power grid 43 to transmit surplus power output from the solar thermoelectric cogeneration panel 41 to the power grid.
[0087] In this embodiment, the circulating medium flowing out of the outlet 154 of the first diverting valve 15 first enters the inlet 211 of the radiator 21, then flows from the outlet 212 of the radiator 21 to the inlet 111 of the evaporator 11, and finally returns from the outlet 112 of the evaporator 11 to the inlet 121 of the first compressor 12.
[0088] After passing through the first compressor 12, the temperature of the circulating medium rises, and part of the circulating medium flows back to the first heat exchanger 13 to heat the shower water, and then flows to the radiator 21; the remaining part of the circulating medium flows directly to the radiator 21, thus forming a circulating flow path.
[0089] In the aforementioned cycle, the circulating medium in radiator 21 heats the air flowing through it, raising its temperature. After exiting radiator 21, the circulating medium cools and flows back to evaporator 11, further cooling and dehumidifying the air. In other words, the air in the swimming pool first flows through evaporator 11 and is cooled, its humidity decreasing, transforming from humid and cold air to dry and cold air. This dry and cold air then flows through radiator 21 and is heated, further transforming into dry and warm air.
[0090] Therefore, the system of this embodiment can heat and dehumidify the air in the swimming pool, thereby improving the comfort experience of swimmers in winter.
[0091] like Figure 5 As shown, a heat exchange pipe 410 is provided on the back of the solar thermoelectric cogeneration panel 41 in a spiral or tortuous manner. The heat exchange pipe 410 has an inlet 411 and an outlet 412. The outlet 412 of the heat exchange pipe 410 is connected to the inlet 315 of the third heat exchanger 31; the outlet 316 of the third heat exchanger 31 is connected to the inlet of the heat exchange pipe 410. In this way, a circulation pipe is formed between the heat exchange pipe 410 and the third heat exchanger 31, so that while the solar thermoelectric cogeneration panel 41 transmits electricity to the outside, it also provides hot fluid to the third heat exchanger 31, providing a heat source for the system.
[0092] Inverter 42 is electrically connected to the second compressor 44 and is used to supply power to the second compressor 44.
[0093] like Figure 5 As shown, the ground source heat pump system 32 is connected to the third heat exchanger 31 through a pipeline. At this time, the third heat exchanger is used as an evaporator to make full use of geothermal energy to heat the pool water temperature.
[0094] The outlet 314 of the third heat exchanger 31 is connected to the inlet 453 of the third diverting valve 45, the outlet 454 of the third diverting valve 45 is connected to the inlet of the second compressor 44, the outlet of the second compressor 44 is connected to the inlet 451 of the third diverting valve 45, the outlet 452 of the third diverting valve 45 is connected to the inlet 143 of the second heat exchanger 14, and the outlet 144 of the second heat exchanger 14 is connected to the inlet 313 of the third heat exchanger 31. Thus, a circulating flow path is formed between the third heat exchanger 31, the second compressor 44, and the second heat exchanger 14. The second compressor 44 pressurizes the circulating medium, further increasing its temperature, and it exchanges heat with the water in the pool 17 within the second heat exchanger 14 to heat the pool water.
[0095] The energy utilization system 40 in this embodiment is suitable for winter conditions when the weather is cold, the water temperature in the swimming pool is low, and the air temperature is low but the humidity is high. The energy transmission system 40 in this embodiment uses a solar thermoelectric co-generation panel 41 to power the first compressor 12 and the second compressor 44, saving electricity from traditional energy sources. The heated circulating medium is used for dehumidifying and heating the air in the swimming pool, as well as heating the shower water. Furthermore, the heat output from the solar thermoelectric co-generation panel and geothermal energy can be used to heat the pool water. The energy utilization system 40 in this embodiment has a high energy recycling rate, low overall energy consumption, and significantly reduced operating costs.
[0096] Fifth Implementation Method
[0097] The energy integrated utilization system 50 has both a first compressor 12 and a second compressor 44. The first compressor 12 is mainly used to pressurize the circulating medium after obtaining energy from the air to increase its temperature, so as to further serve as a heat source for shower or pool water.
[0098] The second compressor 44 is mainly used to pressurize the circulating medium after obtaining energy from the underground pipe system to increase its temperature, so as to heat the pool water when the heat obtained from the air is insufficient (such as in winter).
[0099] The integrated energy utilization system 50 includes a first heat exchanger 13, a second heat exchanger 14, and a third heat exchanger 31. The first heat exchanger 13 is connected to the first compressor 12 and is primarily used to heat shower water. The second heat exchanger 14 is connected to both the first compressor 12 and the second compressor 44. For example, in summer, the second heat exchanger 14 primarily uses the high-temperature circulating medium supplied by the first compressor 12 to heat the pool water. In winter, for example, the second heat exchanger 14 primarily uses the high-temperature circulating medium supplied by the second compressor 44 to heat the pool water. Furthermore, before entering the second compressor 44, the circulating medium is preheated in the third heat exchanger 31 by hot water produced by the underground pipe system and / or the solar thermal power cogeneration panels.
[0100] First, the structure of the system will be explained in detail.
[0101] Evaporator 11, radiator 21, and fan 19 are sequentially connected by pipes. When fan 19 is turned on, air passes sequentially through evaporator 11 and radiator 21. Evaporator 11 is used to cool the air in the swimming pool to reduce humidity. The circulating medium absorbs heat from the air as it flows through evaporator 11, causing its temperature to rise. The outlet 112 of evaporator 11 is connected to flow path c and flow path d. Flow path c is further connected to the inlet 151 of first diverting valve 15, while flow path d is further connected to the inlet 333 of second diverting valve 33. The outlet 152 of first diverting valve 15 and the outlet 334 of second diverting valve 33 are connected to the inlet 121 of first compressor 12.
[0102] In this system, the outlet 122 of the first compressor 12 is connected to the inlet 131 of the first heat exchanger 13 via a balancing valve 51; and the outlet 122 of the first compressor 12 is connected to the inlet 153 of the first diverting valve 15. That is, a portion of the circulating medium flowing out of the first compressor 12 flows into the first heat exchanger 13 to heat shower water, and the balancing valve 51 is used to adjust the flow rate of the circulating medium through the first heat exchanger 13. The outlet 154 of the first diverting valve 15 and the outlet 132 of the first heat exchanger 13 are connected together via a pipeline 510.
[0103] The aforementioned pipeline 510 is divided into two flow paths, a and b, where flow path a is connected to the first end of valve 52, and flow path b is connected to the first end of valve 53.
[0104] Specifically, for flow path a, the second end of valve 52 is connected to the inlet 331 of the second diverting valve 33, and the outlet 332 of the second diverting valve 33 is connected to the inlet 311 of the third heat exchanger 31. In the third heat exchanger 31, its inlet 311 and outlet 312 are connected via internal piping, and its inlet 313 and outlet 314 are connected via internal piping. The outlet 312 of the third heat exchanger 31 is connected to the first end of valve 22 via piping.
[0105] The third heat exchanger 31 and the ground source heat pump system 32 are connected by a pipeline to form a circulation loop. This embodiment utilizes the relatively constant temperature of the ground to cool the circulating medium in the system during summer and to heat the circulating medium in the system during winter.
[0106] For flow path b, the second end of valve 53 is connected to the first ends of valve 54 and valve 55, respectively. The second end of valve 54 is connected to the inlet 141 of the second heat exchanger 14, and the outlet 142 of the second heat exchanger 14 is connected to the first end of valve 22 via a pipeline. The second end of valve 55 is directly connected to the first end of valve 22.
[0107] The first end of valve 22 is also connected to the first end of valve 23, and the second end of valve 23 is further connected to the inlet 211 of radiator 21. The outlet 212 of radiator 21 is connected to the second end of valve 22. The second end of valve 22 is connected to the first end of balancing valve 56, and the second end of balancing valve 56 is connected to the inlet 111 of evaporator 11. Valves 22 and 23 can be used to adjust whether the circulating medium needs to pass through radiator 21. When valve 22 is open and valve 23 is closed, the circulating medium does not flow through radiator 21. When valve 22 is closed and valve 23 is open, the circulating medium flows through radiator 21 to warm the dehumidified air, thereby improving the comfort of people in the swimming pool during winter or other cold weather.
[0108] The above constitutes part of the composition of the comprehensive energy utilization system 50, and the remaining part of the composition of the comprehensive energy utilization system 50 will be explained below.
[0109] In this system, the solar thermal power cogeneration panel 41 is connected to the inverter 42, which converts direct current (DC) to alternating current (AC). The inverter 42 is electrically connected to the first compressor 12 and the second compressor 44, supplying power to them. Furthermore, the inverter 42 can also be connected to the power grid 43 to transmit surplus power output from the solar thermal power cogeneration panel 41 to the grid.
[0110] The back of the solar thermoelectric cogeneration panel 41 is provided with a heat exchange pipe 410 in a spiral or tortuous manner. The heat exchange pipe 410 has an inlet 411 and an outlet 412. The outlet 412 of the heat exchange pipe 410 is connected to the inlet 315 of the third heat exchanger 31; the outlet 316 of the third heat exchanger 31 is connected to the inlet of the heat exchange pipe 410. In this way, a circulation pipe is formed between the heat exchange pipe 410 and the third heat exchanger 31, so that while the solar thermoelectric cogeneration panel 41 transmits electricity to the outside, it also provides hot fluid to the third heat exchanger 31 for heating the pool water.
[0111] The outlet 314 of the third heat exchanger 31 is connected to the inlet 453 of the third diverting valve 45, the outlet 454 of the third diverting valve 45 is connected to the inlet of the second compressor 44, the outlet of the second compressor 44 is connected to the inlet 451 of the third diverting valve, the outlet 452 of the third diverting valve 45 is connected to the inlet 143 of the second heat exchanger 14, and the outlet 144 of the second heat exchanger 14 is connected to the inlet 313 of the third heat exchanger 31 through the balancing valve 57. Thus, a circulating flow path is formed between the third heat exchanger 31, the second compressor 44, and the second heat exchanger 14. The second compressor 44 pressurizes the circulating medium, further increasing its temperature, and exchanges heat with the water in the pool 17 within the second heat exchanger 14 to heat the pool water using heat from the buried pipe system. This is particularly useful in winter when the weather is cold, the water temperature in the swimming pool is low, and the air temperature is low but the humidity is high. The energy transmission system 50 of this embodiment uses a solar thermoelectric cogeneration panel 41 to power the first compressor 12 and the second compressor 44, saving electrical energy. The heated circulating medium is used for dehumidifying and heating the air in the swimming pool, as well as heating the shower water. Furthermore, the heat output from the solar thermoelectric cogeneration panel and geothermal energy can be used to heat the pool water. The energy comprehensive utilization system 50 of this embodiment has a high energy recycling rate, low overall energy consumption, and significantly reduced operating costs.
[0112] The integrated energy utilization system 50 can comprehensively utilize air energy, underground pipe system energy and solar energy in the swimming pool to achieve functions such as air dehumidification, shower water heating and pool water heating in the swimming pool environment. When needed, it can also heat the air in the pool after dehumidification, improve the comfort experience of swimmers, improve the comprehensive utilization rate of energy and save electricity consumption.
[0113] Secondly, based on the above system configuration, the energy comprehensive utilization system 50 of this embodiment has multiple working modes and can adaptively adjust the working mode of the comprehensive utilization system 50 according to the real-time monitored parameter values (such as indoor temperature, humidity, water temperature, and external ambient temperature).
[0114] First working mode
[0115] In summer, both air temperature and humidity are high. To reduce air temperature and humidity, fan 11 is turned on, and the outside air is cooled and dehumidified through evaporator 11.
[0116] In this system, the first directional valve 15, balance valves 51 and 56 are opened, the first heat exchanger 13 and the second heat exchanger 14 are in operation, and valves 53, 54 and 22 are opened accordingly, while valves 52, 55 and 23 are closed. The system workflow diagram at this time is as follows. Figure 1 As shown.
[0117] The first heat exchanger 13 can be, for example, a high-temperature heat recovery unit, and the second heat exchanger can be, for example, a pool constant-temperature multi-energy titanium heat exchanger.
[0118] In the first working mode, the system can cool and dehumidify the air inside the venue, use the energy obtained from the air inside the venue to heat the shower water, and keep the pool water at a constant temperature.
[0119] This system demonstrates significant energy savings, with only the first compressor 12 and fan 19 consuming electrical energy, resulting in a low load. In summer, the air source heat pump (i.e., the first compressor 12) has a high COP value, around 6-7. This system can utilize energy extracted from the air to produce hot water for showers and maintain a constant pool water temperature. Furthermore, the system can utilize solar power to supply electricity, with surplus power also supplied to the power grid.
[0120] Second working mode
[0121] In spring or autumn, the air temperature is low but the humidity is high, so this system needs to dehumidify the air before heating it up.
[0122] In this system, fan 19 is turned on, first diverting valve 15 is opened, valves 53, 54, and 23 are opened, and valves 52, 55, and 22 are closed. The system workflow at this time is as follows: Figure 2 As shown.
[0123] This system can heat and dehumidify the air inside the building, and use energy extracted from the air to heat the shower water and keep the pool water at a constant temperature.
[0124] Third working mode
[0125] In extremely hot summer conditions, the air temperature and humidity are high, and the pool water temperature is already high, which cannot cool the circulating medium. Under such conditions, this system utilizes the characteristic that the ground temperature in the buried pipe system is basically constant, and uses the buried pipe system and the third heat exchanger 31 to cool the circulating medium.
[0126] In this system, fan 19 is turned on, second diverter valve 33 is opened, balancing valves 51 and 56 are opened, and valves 52, 53, 54, and 22 are opened. Valve 55 and 23 are closed. The system workflow is as follows: Figure 3 As shown.
[0127] It should be noted that this system controls the opening and closing of valve 53 based on the pool water temperature. When the pool water temperature exceeds the first threshold (high pool water temperature), valve 53 is closed, and the circulating medium does not flow through the second heat exchanger 14, but instead flows entirely through the third heat exchanger 31, utilizing the underground pipe system and the third heat exchanger 31 to lower the temperature of the circulating medium. When the pool water temperature is below the second threshold (the second threshold is less than the first threshold), valve 53 is opened, and the circulating medium flows through the second heat exchanger 14 to raise the temperature of the pool water, thereby maintaining the pool water temperature between the second and first thresholds.
[0128] Fourth working mode
[0129] In winter, the air temperature is low, the humidity is high, and the pool water temperature is low. Under these conditions, this system utilizes the characteristic of a relatively constant ground temperature in the buried pipe system, using the buried pipe system and the third heat exchanger 31 as the circulating medium for heating. Furthermore, this system can also utilize hot water generated by the thermoelectric twin of the solar thermal power co-generation panel 41 as the circulating medium for heating.
[0130] Specifically, in this system, fan 19 is turned on, and the first compressor 12 and the second compressor 44 are turned on; balancing valves 51, 56, and 57 are opened. The first heat exchanger 13, the second heat exchanger 14, and the third heat exchanger 31 are turned on. Valves 53, 55, and 23 are opened, and valves 52, 54, and 22 are closed. The system workflow is as follows: Figure 4 and Figure 5 As shown. In winter, the COP value of the ground source heat pump (i.e., the second compressor 44) is high, around 5 to 6 (while the COP value of the air source heat pump is only around 1 when the temperature is below zero in winter, thus maximizing its advantages and minimizing its disadvantages).
[0131] In the fourth working mode, the system can dehumidify the air in the venue, maintain a constant air temperature, produce shower water using energy obtained from the air, and heat the pool water using underground pipe systems and solar energy to keep the pool water at a constant temperature.
[0132] Fifth Implementation Method

The integrated utilization machine 100 includes a housing 110. A first compressor 12 and a second compressor 44 are installed inside the housing 110. The first compressor 12 is mainly used to pressurize the circulating medium after obtaining energy from the air to increase its temperature, thereby further serving as a heat source for shower or pool water.
[0134] The second compressor 44 is mainly used to pressurize the circulating medium after obtaining energy from the underground pipe system to increase its temperature, so as to heat the pool water when the heat obtained from the air is insufficient (such as in winter).
[0135] A first heat exchanger 13, a second heat exchanger 14, and a third heat exchanger 31 are installed inside the housing 110. The first heat exchanger 13 is connected to the first compressor 12 and is primarily used to heat shower water. The second heat exchanger 14 is connected to both the first compressor 12 and the second compressor 44. For example, in summer, the second heat exchanger 14 primarily uses the high-temperature circulating medium supplied by the first compressor 12 to heat the pool water. In winter, for example, the second heat exchanger 14 primarily uses the high-temperature circulating medium supplied by the second compressor 44 to heat the pool water. Furthermore, before entering the second compressor 44, the circulating medium is preheated in the third heat exchanger 31 by hot water produced by the underground pipe system and / or the solar thermal power cogeneration panel.
[0136] The internal system configuration of the all-in-one machine 100 can be any of the system structures in the first to fifth embodiments.

[0144] In addition, the system may also include an ambient temperature sensor 64 and a domestic shower water temperature sensor 66 for detecting the temperature of the external environment of the swimming pool and the domestic shower water; the controller 65 is signal-connected to the ambient temperature sensor 64 and the domestic shower water temperature sensor 66.

The aforementioned parameter information may also include, for example, ambient temperature information.
[0148] Based on the parameter information, the target operating mode of the system is determined. The target operating mode can be, for example, any one of the first, second, third, and fourth operating modes in the fifth embodiment.
[0149] Adjust the system to the target operating mode. Connect the controller to each valve and adjust the on / off state of each valve to adjust the system to the target operating mode.
[0150] Eighth Implementation Method
[0151] like Figure 11 As shown, the energy utilization system of this embodiment also includes a fresh air unit 180. A mixing chamber 181 is formed in the area between the evaporator 11 and the radiator 21 on the duct 18. The fresh air unit 180 includes a fresh air duct 182 and a fresh air valve 183 installed on the fresh air duct 182. The inlet of the fresh air duct 182 is connected to the outside, and the outlet of the fresh air duct 182 is connected to the mixing chamber 181. The fresh air valve 183 can be, for example, an electronic valve, and is signal-connected to the controller 65, so that it can be opened periodically or according to the indoor air quality to replenish fresh air into the room.
[0152] In some embodiments, the fresh air unit 180 may further include an exhaust duct 184, the inlet of which is connected to the mixing chamber 181, and the outlet of which is connected to the outside. An exhaust valve 185 may be installed on the exhaust duct 184, which may be connected to the controller 65 for example, so that it can be opened at regular intervals or according to changes in indoor air quality to exhaust indoor stale air.
[0153] The aforementioned fresh air unit 180 can replenish fresh air or expel stale air according to the indoor air quality, thereby improving the indoor air quality.
[0154] In summary, this invention provides an energy comprehensive utilization system and method suitable for swimming pools. This system integrates the following three systems into a single device, achieving comprehensive and coordinated utilization of multiple energy sources, greatly improving the efficiency of new energy utilization, reducing traditional energy consumption, and possessing significant energy-saving implications:
[0155] 1. Latent Heat Recovery System. This system utilizes a dehumidification heat recovery unit to recover and utilize heat from the air, achieving a constant temperature and humidity in indoor air. It mainly consists of an evaporator, compressor (dehumidifying heat pump), heat exchanger (condenser), diverting valve, and piping. The evaporator dehumidifies the airflow passing through it, reducing its temperature and humidity. The first compressor, connected to the evaporator, pressurizes and increases the temperature of the first circulating medium. The heat exchanger connects to both the evaporator and the first compressor, forming a first circulation loop for the first circulating medium. The first circulating medium absorbs heat from the airflow as it passes through the evaporator, its temperature rises as it flows through the first compressor, and it is then used to heat the fluid to be heated (domestic hot water and pool water) as it flows through the heat exchanger. This system can simultaneously dehumidify the air in swimming pools or other humid environments and recover and utilize the heat from the air, achieving latent heat recovery from humid air—heating domestic hot water, pool water, and storing heat in underground pipe systems under extremely hot summer conditions, significantly improving energy efficiency.
[0156] 2. Geothermal Energy Utilization System. By integrating ground source heat pump units, the system achieves comprehensive utilization of geothermal energy. In spring, summer, and autumn, it mainly utilizes heat energy recovered from the air, while in winter, it utilizes geothermal energy from the underground soil. This keeps the COP value between 5 and 7 throughout the entire operating period, thereby achieving significant energy savings.
[0157] 3. Solar Energy Utilization System. Through thermoelectric cogeneration panels, a scheme for simultaneous utilization of photovoltaic and solar thermal energy is realized. The electricity generated by photovoltaic power generation becomes the power source of the integrated equipment after passing through an inverter. The solar thermal energy absorbed by the system due to improved power generation efficiency (solar panel power generation and cooling) is also fully utilized within the system, becoming part of the heat source.
[0158] It is precisely because the above three thermal energy utilization systems are integrated into a single device that swimming pools (or other damp places) become low-carbon swimming pools, or even zero-carbon swimming pools.
[0159] The energy comprehensive utilization system and method apparatus of this application have been described in detail with reference to the preferred technical solutions. However, it should be noted that, without departing from the spirit of this application, those skilled in the art can make any modifications, alterations, and variations based on the above disclosure. This application includes the above-described specific embodiments and any equivalent forms.
