[0057] Other objects and advantages of the present application will become apparent from the following preferred embodiments of the present application.

[0058] First embodiment

[0059] Figure 1 A system schematic diagram of the energy comprehensive utilization system 10 according to an embodiment of the present application is shown.

[0060] As Figure 1 shown, an energy comprehensive utilization system for a swimming pool or a humid place has an evaporator 11 for adjusting the temperature and / or humidity in the swimming pool or other humid place. The application is described below by taking the application in the swimming pool as an example, but it should be clear that the system can also be applied to other similar humid scenes.

[0061] In summer, the indoor air of the swimming pool is hot and humid. The system can cool and dehumidify the hot and humid air in the swimming pool, and use the heat obtained from the indoor environment of the swimming pool to heat the shower water and the pool water, so as to realize efficient use of energy. The excess heat can be introduced into the underground through the buried pipe system for storage.

[0062] Specifically, the system comprises a first compressor 12, a first heat exchanger 13 and a second heat exchanger 14. The flow inlet 121 of the first compressor 12 is in communication with the flow outlet 112 of the evaporator 11. The flow outlet 122 of the first compressor 12 is in communication with the flow inlet 131 of the first heat exchanger 13. The flow outlet 132 of the first heat exchanger 13 is in communication with the flow inlet 141 of the second heat exchanger 14. The flow outlet of the second heat exchanger 14 is in communication with the flow inlet 111 of the evaporator 11.

[0063] The first heat exchanger 13 is in communication with the shower equipment 16 for heating the shower water. The second heat exchanger 14 is in communication with the pool 17 for heating the water in the pool 17.

[0064] In the embodiment, the circulating medium (for example, R22, R401 or the like) flowing through the second heat exchanger 14 and exchanging heat with the water in the pool 17 has a reduced temperature, and flows to the flow inlet 111 of the evaporator 11. The circulating medium exchanges heat with the air in the swimming pool at the evaporator 11 to cool the indoor air. After the temperature of the indoor air is reduced, the humidity of the indoor air is reduced, for example, from 28 degrees Celsius and 80% relative humidity to 24 degrees Celsius and 40% relative humidity. The comfort experience of the people in the swimming pool is improved, and part of the energy is obtained from the air in the swimming pool. The temperature of the circulating medium is increased.

[0065] The circulating medium with the increased temperature flows from the evaporator 11 to the first compressor 12. After being compressed, the temperature of the circulating medium is further increased. Part of the circulating medium flows through the first heat exchanger 13 to heat the shower water, and then flows from the first heat exchanger 13 to the second heat exchanger 14 to heat the water in the pool. Since the heat used for the shower water is relatively small, the heat of the part of the circulating medium can meet the use requirement. The remaining part of the circulating medium directly flows into the second heat exchanger 14 to heat the water in the pool. The temperature of the circulating medium flowing through the second heat exchanger 14 is reduced, and then flows into the evaporator 11, so as to form a circulation loop.

[0066] To facilitate the adjustment of the flow path, the system further comprises a first switching valve 15, which can have two switchable flow paths, for example. The first flow inlet 151 of the first switching valve 15 is in communication with the flow outlet 112 of the evaporator 11, and the first flow outlet 152 of the first switching valve 15 is in communication with the flow inlet 121 of the first compressor 12. The second flow inlet 153 of the first switching valve 15 is in communication with the flow outlet 122 of the first compressor 12, and the second flow outlet 154 of the first switching valve 15 is in communication with the flow inlet 141 of the second heat exchanger 14. In this embodiment, the first flow inlet 151 of the first switching valve 15 is in communication with the first flow outlet 152 thereof, and the second flow inlet 153 of the first switching valve 15 is in communication with the second flow outlet 154 thereof. The flow path state of the system can be adjusted as needed by adjusting the first switching valve 15.

[0067] The system can use the temperature of the indoor air of the natatorium to heat the shower water and the pool water, thereby improving the energy utilization rate, and after the temperature of the indoor air decreases, the humidity decreases, the humid hot air becomes dry cool air, and the comfort experience of the swimmers is improved.

[0068] Second embodiment

[0069] The present embodiment is further improved on the basis of the first embodiment.

[0070] Figure 2 The system principle diagram of the energy comprehensive utilization system 20 of another embodiment of the present application is exemplarily shown.

[0071] In spring or autumn, the indoor temperature of the natatorium is low, but the humidity in the indoor environment is still high, and the indoor environment air of the natatorium needs to be heated and dehumidified.

[0072] In the present embodiment, the circulating medium flowing out of the flow outlet 142 of the second heat exchanger 14 first flows into the flow inlet 211 of the radiator 21, then flows from the flow outlet 212 of the radiator 21 to the flow inlet 111 of the evaporator 11, and finally returns to the flow inlet 121 of the first compressor 12 from the flow outlet 112 of the evaporator 11.

[0073] In the above circulation, the circulating medium in the radiator 21 first heats the air flowing through the radiator 21 to increase the temperature of the air. After the circulating medium flows out of the radiator 21, the temperature decreases, and then the circulating medium flows into the evaporator 11 to cool and dehumidify the air. In other words, the air in the natatorium first flows through the evaporator 11 to be cooled and dehumidified, and the humid cold air becomes dry cold air. The dry cold air then flows through the radiator 21 to be heated, and thus the dry cold air further becomes dry warm air.

[0074] Therefore, the system of the embodiment can warm and dehumidify the air in the swimming pool, thereby improving the comfort experience of the swimmer in the cold spring and autumn.

[0075] To achieve the above function, the system of the embodiment includes valves 22 and 23. The valve 22 is connected in series in the pipeline from the flow outlet 142 of the second heat exchanger 14 to the flow inlet 111 of the evaporator 11, one end of the pipeline 213 is connected to the pipeline on the flow-in side of the valve 22, the other end of the pipeline 213 is connected to the flow inlet 211 of the radiator 21, and the valve 23 is connected in series on the pipeline 213; one end of the pipeline 214 is connected to the pipeline on the flow-out side of the valve 22, and the other end of the pipeline 214 is connected to the flow outlet 212 of the radiator 21.

[0076] In the embodiment, when the circulating medium needs to flow through the radiator 21, the valve 22 is closed and the valve 23 is opened; when the circulating medium does not need to flow through the radiator 21, the valve 22 is opened and the valve 23 is closed. The valves 22 and 23 can adjust between the cooling and dehumidifying mode and the warming and dehumidifying mode of the system, thereby adapting to different indoor temperature and humidity conditions of the swimming pool.

[0077] Third embodiment

[0078] In the case of extremely hot summer, for example, the ambient temperature is greater than 40 degrees Celsius, the water temperature in the pool and the room temperature in the swimming pool are both high, and it is difficult to use the pool water to cool and dehumidify the indoor air.

[0079] To solve the above technical problems, the embodiment proposes a further solution. Figure 3 The system principle diagram of the energy comprehensive utilization system of another embodiment of the application.

[0080] As shown in Figure 3 The energy system 30 further includes a third heat exchanger 31 and a ground source heat pump system 32, which are connected by a pipeline to form a circulation loop. The embodiment utilizes the relatively constant characteristics of the stratum temperature. In summer, the excess heat in the system is introduced into the ground by the circulation loop, and in winter, the heat in the ground is extracted into the system by the circulation loop.

[0081] Only the differences between the embodiment and the first embodiment are described below. Specifically, as shown in Figure 3 In the embodiment, the circulating medium is divided into three paths after flowing out of the first compressor 12.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Fourth Implementation Method

[0087] 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.

[0088] 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.

[0089] After passing through the first compressor 12, the temperature of the circulating medium is raised, part of the circulating medium is circulated to the first heat exchanger 13 to heat the shower water, and then flows to the radiator 21; the remaining circulating medium directly flows to the radiator 21, thereby forming a circulating flow path.

[0090] In the above cycle, the circulating medium in the radiator 21 heats the air flowing through the radiator 21, thereby increasing the temperature of the air. After the circulating medium flows out of the radiator 21, the temperature of the circulating medium is reduced, and then the circulating medium flows into the evaporator 11 to cool and dehumidify the air. In other words, the air in the swimming pool first flows through the evaporator 11 to be cooled and dehumidified, and then becomes dry and cold air. The dry and cold air is heated in the radiator 21, thereby further becoming dry and warm air.

[0091] Therefore, the system of the embodiment can heat and dehumidify the air in the swimming pool, thereby improving the comfort experience of the swimmer in winter.

[0092] As shown in Figure 5 The back of the solar thermoelectric co-generation panel 41 is provided with a heat exchange pipe 410 in a spiral or zigzag 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 circulating pipe is formed between the heat exchange pipe 410 and the third heat exchanger 31, so that the solar thermoelectric co-generation panel 41 can supply electricity to the outside while providing hot fluid to the third heat exchanger 31 to provide a heat source for the system.

[0093] The inverter 42 is electrically connected to the second compressor 44 for supplying power to the second compressor 44.

[0094] As shown in Figure 5 The ground source heat pump system 32 is connected to the third heat exchanger 31 through a pipe, and the third heat exchanger is used as an evaporator at this time, so as to fully utilize the geothermal energy to heat the pool water.

[0095] The flow outlet 314 of the third heat exchanger 31 is in communication with the flow inlet 453 of the third switching valve 45, the flow outlet 454 of the third switching valve 45 is in communication with the flow inlet of the second compressor 44, the flow outlet of the second compressor 44 is in communication with the flow inlet 451 of the third switching valve 45, the flow outlet 452 of the third switching valve 45 is in communication with the flow inlet 143 of the second heat exchanger 14, and the flow outlet 144 of the second heat exchanger 14 is in communication with the flow 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, the temperature of the circulating medium is further increased, and heat exchange is performed between the circulating medium and the water in the swimming pool 17 in the second heat exchanger 14 for heating the swimming pool water.

[0096] The energy comprehensive utilization system 40 in the embodiment is suitable for the case that the weather is cold in winter, the water temperature in the natatorium is low, and the air temperature is low but the humidity is high. The energy comprehensive utilization system 40 in the embodiment uses the solar heat and power cogeneration panel 41 to supply power for the first compressor 12 and the second compressor 44, thereby saving the electric energy of the traditional energy; the circulating medium is heated and used for dehumidification and temperature increase of the air in the natatorium and heating of the shower water. The heat output by the solar heat and power cogeneration panel and the geothermal heat can be used for heating the swimming pool water. The energy comprehensive utilization system 40 in the embodiment has a high energy recycling rate, a low comprehensive energy consumption and a greatly reduced operation cost.

[0097] Fifth Embodiment

[0098] In the energy comprehensive utilization system 50, the first compressor 12 and the second compressor 44 are provided simultaneously. The first compressor 12 is mainly used for pressurizing the circulating medium after energy is obtained from the air to increase the temperature of the circulating medium, thereby further serving as a heat source for the shower water or the swimming pool water.

[0099] The second compressor 44 is mainly used for pressurizing the circulating medium after energy is obtained from the ground heat exchanger system to increase the temperature of the circulating medium, thereby supplying heat for the swimming pool water when the heat obtained from the air is insufficient (for example, in winter).

[0100] In the energy comprehensive utilization system 50, there are simultaneously the first heat exchanger 13, the second heat exchanger 14 and the third heat exchanger 31. The first heat exchanger 13 is in communication with the first compressor 12 and is mainly used for heating shower water. The second heat exchanger 14 is in communication with the first compressor 12 and the second compressor 44 respectively. For example, in summer, the second heat exchanger 14 mainly uses the high-temperature circulating medium supplied by the first compressor 12 to heat swimming pool water. For example, in winter, the second heat exchanger 14 mainly uses the high-temperature circulating medium supplied by the second compressor 44 to heat swimming pool water. Moreover, before entering the second compressor 44, the circulating medium is preheated in the third heat exchanger 31 by the hot water produced by the ground buried pipe system and / or the solar thermal cogeneration solar panel.

[0101] First, the structure of the system is described in detail.

[0102] The evaporator 11, the radiator 21 and the fan 19 are connected in sequence by pipes. When the fan 19 is turned on, air passes through the evaporator 11 and the radiator 21 in sequence. The evaporator 11 is used to cool the air in the swimming pool to reduce the humidity of the air. The circulating medium flowing through the evaporator 11 absorbs heat from the air and its temperature rises. The flow outlet 112 of the evaporator 11 is in communication with the flow path c and the flow path d. The flow path c is further in communication with the flow inlet 151 of the first switching valve 15, and the flow path d is further in communication with the flow inlet 333 of the second switching valve 33. The flow outlet 152 of the first switching valve 15 and the flow outlet 334 of the second switching valve 33 are in communication with the flow inlet 121 of the first compressor 12.

[0103] In the system, the flow outlet 122 of the first compressor 12 is in communication with the flow inlet 131 of the first heat exchanger 13 through the balance valve 51; and the flow outlet 122 of the first compressor 12 is in communication with the flow inlet 153 of the first switching valve 15. That is, part of the circulating medium flowing out of the first compressor 12 passes through the first heat exchanger 13 to heat the shower water, and the balance valve 51 is used to adjust the flow of the circulating medium through the first heat exchanger 13. The flow outlet 154 of the first switching valve 15 and the flow outlet 132 of the first heat exchanger 13 are collected together through the pipeline 510.

[0104] The above-mentioned pipeline 510 is divided into two flow paths a and b, wherein the flow path a is in communication with the first end of the valve 52, and the flow path b is in communication with the first end of the valve 53.

[0105] Specifically, for flow path a, the second end of valve 52 is in communication with the flow inlet 331 of the second diverter valve 33, and the flow outlet 332 of the second diverter valve 33 is in communication with the flow inlet 311 of the third heat exchanger 31. In the third heat exchanger 31, the flow inlet 311 is in communication with the flow outlet 312 through internal piping, and the flow inlet 313 is in communication with the flow outlet 314 through internal piping. The flow outlet 312 of the third heat exchanger 31 is in communication with the first end of the valve 22 through piping.

[0106] The third heat exchanger 31 and the ground source heat pump system 32 are connected through piping to form a circulation loop. The present embodiment takes advantage of the relatively constant temperature of the ground layer. In summer, the circulation loop is used to cool the circulating medium in the system, while in winter, the circulation loop is used to heat the circulating medium in the system.

[0107] For flow path b, the second end of the valve 53 is in communication with the first end of the valve 54 and the first end of the valve 55, respectively. The second end of the valve 54 is in communication with the flow inlet 141 of the second heat exchanger 14, and the flow outlet 142 of the second heat exchanger 14 is collected through piping to the first end of the valve 22. The second end of the valve 55 is directly in communication with the first end of the valve 22.

[0108] The first end of the valve 22 is also in communication with the first end of the valve 23, and the second end of the valve 23 is further in communication with the flow inlet 211 of the radiator 21, and the flow outlet 212 of the radiator 21 is in communication with the second end of the valve 22. The second end of the valve 22 is in communication with the first end of the balance valve 56, and the second end of the balance valve 56 is in communication with the flow inlet 111 of the evaporator 11. By adjusting the valves 22 and 23, it can be determined whether the circulating medium needs to pass through the radiator 21. When the valve 22 is open and the valve 23 is closed, the circulating medium does not flow through the radiator 21, and when the valve 22 is closed and the valve 23 is open, the circulating medium flows through the radiator 21 to warm the air after dehumidification, thereby improving the comfort of the people in the swimming pool in winter or other cold weather.

[0109] The above forms part of the energy comprehensive utilization system 50, and the remaining part of the energy comprehensive utilization system 50 is described below.

[0110] In the present system, the solar thermal and power cogeneration panel 41 is connected to the inverter 42, which is used to convert direct current to alternating current. The inverter 42 is electrically connected to the first compressor 12 and the second compressor 44, and is used to supply power to the first compressor 12 and the second compressor 44. In addition, the inverter 42 can also be connected to the power grid 43, and the excess power output by the solar thermal and power cogeneration panel 41 is delivered to the power grid.

[0111] The back of the solar-thermal cogeneration panel 41 is provided with a heat exchange pipe 410 in a spiral or zigzag 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 the solar-thermal cogeneration panel 41 supplies electricity to the outside while providing hot fluid to the third heat exchanger 31 for heating the pool water.

[0112] The outlet 314 of the third heat exchanger 31 is connected to the inlet 453 of the third diverter valve 45, the outlet 454 of the third diverter 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 diverter valve, the outlet 452 of the third diverter 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 balance valve 57. In this way, a circulation 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, the temperature of the circulating medium is further increased, and heat exchange is performed between the circulating medium and the water in the pool 17 in the second heat exchanger 14 for heating the pool water using the heat in the ground source heat pump system. In winter, 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 transfer system 50 of the present embodiment uses the solar-thermal cogeneration panel 41 to supply power to the first compressor 12 and the second compressor 44, saving electricity; the heated circulating medium is used to dehumidify and heat the air in the swimming pool and to heat the shower water. The heat output by the solar-thermal cogeneration panel can also be used to heat the pool water. The energy comprehensive utilization system 50 of the present embodiment has a high energy recycling rate, low comprehensive energy consumption and significantly reduced operating costs.

[0113] The energy comprehensive utilization system 50 can comprehensively utilize the air energy in the swimming pool, the ground source heat pump system energy and the solar energy, realize the functions of air dehumidification, shower water heating, pool water heating and the like in the swimming pool environment, and can also heat the air in the swimming pool after dehumidification when needed, improve the comfort experience of swimmers, and improve the comprehensive utilization rate of energy and save electricity consumption.

[0114] Secondly, based on the above system configuration, the energy comprehensive utilization system 50 of the present 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 the temperature, humidity, water temperature, ambient temperature, etc. in the pool).

[0115] First working mode

[0116] In summer, the air temperature and humidity are high, in order to reduce the air temperature and humidity, the fan 19 is opened, the external air is cooled and dehumidified at the evaporator 11.

[0117] In the system, the first reversing valve 15, the balance valve 51 and the balance valve 56 are opened, the first heat exchanger 13 and the second heat exchanger 14 are in working condition, and the corresponding valves 53, 54 and 22 are opened, and the valves 52, 55 and 23 are closed. At this time, the system working flow chart is as shown in Figure 1 .

[0118] The first heat exchanger 13 can be a high-temperature heat recovery device, and the second heat exchanger can be a pool constant-temperature multi-purpose titanium heat exchanger.

[0119] In the first working mode, the system can cool and dehumidify the air in the museum, and use the energy obtained from the air in the museum to heat the shower hot water and keep the pool water constant temperature.

[0120] The energy-saving effect of the system is remarkable, and only the first compressor 12 and the fan 19 work in the system, and the load is small. In summer, the air source heat pump (i.e. the first compressor 12) COP value is about 6~7. The system can use the energy obtained from the air to produce shower hot water and keep the pool water constant temperature. Moreover, solar power can be used to supply power to the system, and the remaining electricity can also be provided to the power grid.

[0121] Second working mode

[0122] In spring or autumn, the air temperature is low but the humidity is high, and the system needs to dehumidify the air before heating.

[0123] In the system, the fan 19 is opened, the first reversing valve 15 is opened, the valves 53, 54 and 23 are opened, and the valves 52, 55 and 22 are closed. At this time, the system working flow chart is as shown in Figure 2 .

[0124] The system can heat and dehumidify the air in the museum, and use the energy obtained from the air in the museum to heat the shower water and keep the pool water constant temperature.

[0125] Third working mode

[0126] In the summer extreme heat working condition, the air temperature and humidity are high, and the pool water temperature itself is already high, and cannot cool the circulating medium. In this working condition, the system uses the characteristics that the ground temperature in the ground source heat pump system is basically constant, and uses the ground source heat pump system and the third heat exchanger 31 to cool the circulating medium.

[0127] In the system, the fan 19 is turned on, the second diverter valve 33 is opened, the balancing valve 51, the balancing valve 56 are opened, and the valves 52, 53, 54 and 22 are opened. The valves 55 and 23 are closed. The system working process is shown in Figure 3

[0128] It should be noted that the system controls the opening and closing of the valve 53 according to the temperature of the pool water. When the pool water temperature exceeds the first threshold value (high pool water temperature), the valve 53 is closed, the circulating medium does not flow through the second heat exchanger 14, but flows through the third heat exchanger 31 entirely, and the temperature of the circulating medium is lowered by the ground source heat pump system and the third heat exchanger 31. When the pool water temperature is lower than the second threshold value (the second threshold value is smaller than the first threshold value), the valve 53 is opened, the circulating medium flows through the second heat exchanger 14 to heat the pool water, so that the temperature of the pool water is maintained between the second threshold value and the first threshold value.

[0129] Fourth working mode

[0130] In winter, the air temperature is low, the humidity is high, and the pool water temperature is low. In this case, the system uses the ground source heat pump system and the third heat exchanger 31 to heat the circulating medium by using the characteristic that the ground temperature in the ground source heat pump system is basically constant. Moreover, the system can also use the hot water generated by the thermoelectric twin production of the solar energy thermoelectric cogeneration panel 41 to heat the circulating medium.

[0131] Specifically, in the system, the fan 19 is turned on, the first compressor 12 and the second compressor 44 are turned on, the balancing valve 51, the balancing valve 56 and the balancing valve 57 are opened, the first heat exchanger 13, the second heat exchanger 14 and the third heat exchanger 31 are opened, the valves 53, 55 and 23 are opened, and the valves 52, 54 and 22 are closed. The system working process is shown in Figure 4 Figure 5 and Figure 5 In winter, the COP value of the ground source heat pump (i.e. the second compressor 44) is high, about 5-6 (while the COP value of the air source heat pump in winter is only about 1, so the system takes advantage of the strengths and avoids the weaknesses).

[0132] In the fourth working mode, the system can dehumidify the air in the hall, maintain the constant temperature of the air, and use the energy obtained from the air to produce shower water, and use the ground source heat pump system and solar energy to heat the pool water, so that the pool water is maintained at a constant temperature.

The first compressor 12 is mainly used for boosting the pressure of circulating medium after energy is obtained from air to improve the temperature of the circulating medium, so as to further serve as a heat source of shower or swimming pool water.

[0135] The second compressor 44 is mainly used for boosting the pressure of circulating medium after energy is obtained from a buried pipe system to improve the temperature of the circulating medium, so as to provide heat for swimming pool water when the heat obtained from air is insufficient (for example, in winter).

For example, in summer, the second heat exchanger 14 mainly uses high-temperature circulating medium supplied by the first compressor 12 to heat swimming pool water. For example, in winter, the second heat exchanger 14 mainly uses high-temperature circulating medium supplied by the second compressor 44 to heat swimming pool water. In addition, the circulating medium is preheated in the third heat exchanger 31 by hot water produced by the buried pipe system and / or solar-thermal cogeneration solar cell panel before entering the second compressor 44.

[0154] Through the fresh air unit 180 described above, fresh air can be supplemented or turbid air can be exhausted according to the indoor air quality, and the indoor air quality is improved.

[0155] In summary, the present application provides an energy comprehensive utilization system and method suitable for swimming pools or other humid places, which integrates the following three systems into one device, realizes the comprehensive utilization of various energies, greatly improves the new energy utilization efficiency, reduces the energy consumption of traditional energy, and has great energy-saving significance.

[0156] 1. Air latent heat recovery system. The air latent heat recovery system is achieved by a dehumidification heat recovery unit, and the indoor air temperature and humidity are kept constant. The system mainly includes an evaporator, a compressor (dehumidification heat pump), a heat exchanger (radiator), a diverter valve and a pipeline. The evaporator is used to dehumidify the air flow passing through the device to reduce the temperature and humidity of the air flow. The first compressor in communication with the evaporator is used to pressurize and increase the temperature of the first circulating medium. The heat exchanger is in communication with the evaporator and the first compressor, respectively, to form a first circulating loop for the flow of the first circulating medium. The first circulating medium absorbs heat from the air flow when passing through the evaporator, and the temperature increases when flowing through the first compressor, and then is used to heat the fluid to be heated (hot water and pool water) when flowing through the heat exchanger. The system can dehumidify the air in the swimming pool or other humid place while recovering and utilizing the heat obtained from the air, realizing the latent heat recovery and utilization of the humid and hot air, heating the hot water, pool water and the ground source heat pump system in summer, and greatly improving the energy utilization efficiency.

[0157] 2. Geothermal energy utilization system. The geothermal energy utilization system is achieved by integrating a ground source heat pump unit. In spring, summer and autumn, the heat energy in the air is mainly recovered and utilized, while in winter, the geothermal energy in the underground soil is utilized, so that the COP value of the entire operation period is maintained between 5 and 7, thereby achieving great energy saving.

[0158] 3. Solar energy utilization system. The solar energy utilization system is achieved by a heat and electricity co-produced solar panel, which realizes a simultaneous utilization scheme of photoelectricity and photothermal. The electricity generated by photoelectricity becomes the power supply of the all-in-one device after being inverted by an inverter. The solar heat energy absorbed due to the improvement of the power generation efficiency (solar panel power generation cooling) is fully utilized in the system as part of the heat source.

[0159] Because the above three heat energy utilization systems are integrated into an integrated device, the swimming pool (or other humid place) becomes a low-carbon swimming pool, or even a zero-carbon swimming pool.

[0160] The energy comprehensive utilization system and method device of the application are described in detail with reference to the preferred technical solutions of the application. However, it should be noted that any modification, modification and change can be made by those skilled in the art on the basis of the above disclosure without departing from the spirit of the application. The application includes the above specific embodiments and any equivalent forms thereof.
