[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning system. Background Art

[0002] Some venues, such as indoor hot springs, swimming pools, and indoor water parks, consume significant energy to operate. Not only does the need to maintain a constant temperature within the swimming pool itself require the removal of humidity, which necessitates additional dehumidification equipment and cooling capacity, increasing operating costs. Recovering and utilizing the heat within the swimming pool can also reduce operating costs. Summary of the Invention

[0006] In an air conditioning system provided by an embodiment of the present invention, the refrigerant liquid in a first evaporator vaporizes and absorbs heat from the liquid at the second liquid outlet of the cooling system. This allows the liquid at the first evaporator outlet to cool and then be reused in the second liquid inlet of the cooling system. The vaporized refrigerant liquid then liquefies and releases heat in a first condenser, which is then absorbed by the liquid flowing into the first condenser from the first liquid outlet of the heating system. This heat is then heated up before the liquid entering the first liquid inlet of the heating system is reused, thereby recovering heat from the heating system and saving energy for the entire swimming pool.

The at least one refrigeration unit includes a second evaporator and a second condenser. One end of the second evaporator is connected to the second liquid outlet of the cooling system, and the other end of the second evaporator is connected to the second liquid inlet of the cooling system. The cooling tower has a cooling tower outlet and a cooling tower inlet, and the cooling tower outlet is connected to the liquid inlet of the second condenser. The cooling tower inlet is connected to the liquid outlet of the second condenser. The supplemental cooling system also includes a cooling circulation pump.

[0020] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0022] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0023] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical connections; direct connections or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0024] In some places, such as indoor hot springs, swimming pools, and indoor water parks, the energy consumption is relatively high. In order to recover the heat in the indoor air and reduce the operating costs, the embodiment of the present invention provides an air-conditioning system. In order to more clearly express the technical solution of this application, the air-conditioning system in the swimming pool is used as an example for illustration. Figure 1 As shown, the air-conditioning system includes a heating system 1, a cooling system 2 and at least one heat pump heat recovery unit 3. The heating system 1 may include one or more of swimming pool water heating equipment, heating equipment and shower heating equipment. The present application does not limit the specific equipment type of the heating system 1, and any equipment that requires heat can be referred to as the heating system 1. The cooling system 2 may include other room air-conditioning refrigeration equipment or other cooling systems. The heat pump heat recovery unit 3 is used to recover the condensation heat generated by the cooling system 2 and transfer the heat to the heating system 1 for use. For example, when the heating system 1 is a swimming pool water heating device, the swimming pool water heating device can transfer the heat to the swimming pool water inlet. In this way, the condensation heat of the indoor air is recovered and utilized, which can reduce the total energy consumption and save operating costs.

[0025] like Figure 1 As shown, the heating system 1 has a first liquid outlet A2 and a first liquid inlet A1. The cooling system 2 has a second liquid outlet B2 and a second liquid inlet B1. At least one heat pump heat recovery unit 3 includes a first evaporator 31 and a first condenser 32. The first condenser liquid inlet D1 can be connected to the first liquid outlet A2 of the heating system 1 through a pipeline, and the first condenser liquid outlet D2 can be connected to the first liquid inlet A1 of the heating system 1 through a pipeline. In this case, the connected heating system 1 and the first condenser 32 can be formed as follows Figure 1 The first path L1 is shown.

[0026] In addition, the first evaporator liquid inlet C1 can be connected to the second liquid outlet B2 of the cooling system 2 through a pipe, and the first evaporator liquid outlet C2 can be connected to the second liquid inlet B1 of the cooling system 2 through a pipe. In this case, the cooling system 2 and the first evaporator 31 connected through the pipe can form a Figure 1 The second path L2 is shown.

[0027] Based on this, the first evaporator 31 contains low-temperature refrigerant. After the liquid in the second path L2 flows into the first evaporator 31 from the second liquid outlet B2 of the cooling system 2, it can exchange heat with the refrigerant in the first evaporator 31. Specifically, the low-temperature refrigerant absorbs heat from the liquid in the second path L2 during this heat exchange process and vaporizes, thereby cooling the liquid in the second path L2. Therefore, the first evaporator 31 in the second path L2 can cool the liquid from the second liquid outlet B2 of the cooling system 2 before discharging it to the second liquid inlet B1 of the cooling system 2. This allows the temperature of the second liquid inlet B1 of the cooling system 2 to be lower than the temperature of the second liquid outlet B2 of the cooling system 2. For example, for ease of explanation, the temperature of the liquid in the second liquid inlet B1 of the cooling system 2 can be referred to as the pre-use temperature, which is generally between 5°C and 10°C. The temperature of the liquid in the second liquid outlet B2 of the cooling system 2 can be referred to as the post-use temperature, which can be between 10°C and 15°C. The post-use temperature of the liquid is higher than the pre-use temperature.

[0028] In addition, the liquid passing through the first condenser 32 undergoes heat exchange with the vaporized refrigerant, and the vaporized refrigerant passes through the first condenser 32 to liquefy and release heat, thereby heating the liquid passing through the first condenser 32 in the first path L1. The liquid from the first liquid outlet A2 of the heating system 1 is heated and then input into the first liquid inlet A1.

[0029] In summary, in the air-conditioning system provided by the embodiment of the present invention, in this way, in the second path L2, the liquid coming out of the second liquid outlet B2 of the cooling system 2 absorbs heat and cools through the first evaporator 31, and then is transported to the cooling system 2 through the second path L2. After receiving the cooled liquid from the first evaporator liquid outlet C2, the cooling system 2 can be circulated back into the cooling system 2 for cooling. In addition, as can be seen from the above, after the first condenser 32 and the first evaporator 31 perform heat conversion through the refrigerant, the temperature of the liquid output by the first condenser 32 will increase. Based on this, the liquid heated by the first condenser 32 can be used in the heating system 1 for heat conversion and recycling. In this way, the liquid in the first path L1 is heated to recover the heat generated by the cooling system 2, saving the energy consumption of the entire swimming pool.

[0030] The structure of the cooling system 2 mentioned above is described below with examples. For example, in some embodiments of the present application, when the humidity is high (such as the summer working conditions of a swimming pool), in order to solve the problem of indoor dehumidification. Figure 2As shown, the cooling system 2 may include a dehumidification component 21 in the air-conditioning unit 100, and the dehumidification component 21 has a cooling liquid inlet and a cooling liquid outlet, and the cooling liquid inlet is connected to the first evaporator liquid outlet C2 (it should be noted that the connection here can be direct or indirect, for example, the indirect connection can be that the liquid enters the second liquid inlet B1 of the cooling system 2 from the first evaporator liquid outlet C2 and then enters the cooling liquid inlet. Of course, it can also be direct, for example, the cooling liquid inlet is equivalent to the second liquid inlet B1, which will not be described in detail later). The cooling liquid outlet is connected to the first evaporator liquid inlet C1 (it should be noted that the connection here can be direct or indirect, for example, the indirect connection can be that the liquid comes out from the cooling liquid outlet of the dehumidification component through the second liquid outlet B2 of the cooling system 2 and then enters the first evaporator liquid inlet C1. Of course, it can also be direct, for example, the cooling liquid outlet is equivalent to the second liquid outlet B2, which will not be described in detail later).

[0031] In this case, the dehumidification component 21 is used to condense the humid air in the indoor swimming pool (the temperature of the humid air in the swimming pool is generally maintained in the range of 27℃ to 29℃) to below the dew point temperature, and after the moisture is precipitated, the water vapor in the air is reduced. Figure 2 As shown, in this way, due to the heat released by the condensation of the wet air, the liquid used for condensation in the dehumidification component 21 is heated, and the liquid at the refrigerant outlet of the dehumidification component 21 can be heated and then transported to the first evaporator 31.

[0032] Furthermore, the heated liquid enters the first evaporator 31 via the second path L2. The refrigerant in the first evaporator 31 absorbs heat from the liquid in the second path L2 and cools it. The cooled liquid then returns to the dehumidifier 21 via the second path L2 for use. The heated and vaporized refrigerant liquefies and releases heat in the first condenser 32, thereby heating the liquid in the first path L1 that has passed through the first condenser 32 and then being delivered to the heating system 1 for use. In this way, the dehumidifier 21 can achieve the purpose of dehumidification and thus realize heat recovery.

[0033] The following examples illustrate the liquid temperature parameters within the above-described structure. For example, in some embodiments of the present application, since the dehumidification temperature of the dehumidification assembly 21 is generally 5°C to 10°C, this is the cooling liquid inlet temperature of the dehumidification assembly 21. After dehumidification of the humid air in the swimming pool, the temperature of the dehumidification assembly 21 can be raised to 10°C to 15°C, which is the cooling liquid outlet temperature of the dehumidification assembly 21.

[0034] The following partially illustrates the above-mentioned temperature parameters. For example, in some embodiments of the present application, the dehumidification temperature required by the dehumidification component 21 is 7°C. After dehumidification by the dehumidification component 21, the temperature of the cold liquid outlet of the dehumidification component 21 can be increased to 12°C. The heated liquid enters the first evaporator 31, exchanges heat with the refrigerant liquid in the first evaporator 31, and is cooled to 7°C. After that, it flows out of the liquid outlet of the first evaporator 31 through the second path L2 and flows into the dehumidification component 21 again for use, thereby forming a cycle.

[0035] For example, the cooling inlet temperature of the dehumidification component 21 can be 5°C, 7°C, and 10°C. The cooling outlet temperature of the dehumidification component 21 can be 10°C, 12°C, and 15°C. The first evaporator inlet temperature C1 can be 10°C, 12°C, and 15°C, and the first evaporator outlet temperature C2 can be 5°C, 7°C, and 10°C.

[0036] Since the indoor temperature of the swimming pool needs to be maintained in the range of 27℃~29℃, the heating system 1 of the present application may also include Figure 2 The air-heating assembly 11 in the air-conditioning unit 100 has a heat supply inlet and a heat supply outlet. The heat supply inlet is connected to the first condenser outlet D2 (the connection mentioned here can be direct or indirect, which will not be repeated here), and the heat supply outlet is connected to the first condenser inlet D1 (the connection mentioned here can be direct or indirect, which will not be repeated here). The air-heating assembly 11 is used to heat the air entering the room so that the indoor temperature is within the range of 27°C to 29°C.

[0037] The following provides some examples of the above temperature parameters. For example, in some embodiments of the present application, the required liquid temperature of the air-heating component 11 can be 42°C to 50°C, that is, the heat supply liquid inlet of the air-heating component 11. Since the air-heating component 11 heats the passing air, some of the heat of the liquid in the air-heating component 11 will be carried away by the air. As a result, the temperature of the heat supply liquid outlet of the air-heating component 11 can be 37°C to 45°C.

[0038] The above-mentioned temperature parameters are partially illustrated below. For example, in some embodiments of the present application, when the liquid temperature required by the wind-heating component 11 is 45°C, the temperature of the heat outlet after passing through the wind-heating component 11 can be 40°C. After the liquid enters the first condenser liquid inlet D1 through the first path L1, it exchanges heat with the refrigerant liquid in the first evaporator 31 for heating, so that the temperature of the first condenser liquid outlet D2 can be 45°C. In this way, the temperature of the liquid entering the wind-heating component 11 from the first path L1 can be 45°C, thereby forming a circulating operation.

[0039] For example, the temperature of the first condenser liquid inlet D1 can be 37°C, 40°C, and 45°C, and the temperature of the first condenser liquid outlet D2 can be 42°C, 45°C, and 50°C. The temperature of the heat supply liquid inlet of the wind-heating component 11 can be 42°C, 45°C, and 50°C, and the temperature of the heat supply liquid outlet of the wind-heating component 11 can be 37°C, 40°C, and 45°C.

[0040] From the above, we can draw the following conclusions:

[0041] The temperature difference ΔT1 of the liquid in the first path L1 before and after passing through the first condenser 32 = 45°C - 40°C = 5°C.

[0042] The temperature difference ΔT2 of the liquid in the second path L2 before and after passing through the first evaporator 31 is 7° C.-12° C.=-5° C.

[0043] In this way, the temperature of the liquid in the first path L1 rises by 5° C., and the temperature of the liquid in the second path L2 drops by 5° C. That is, the heat conversion between the first path L1 and the second path L2 is achieved through the heat pump heat recovery unit 3 .

[0044] It should be noted that:

[0045] The heat pump heat recovery unit 3 may also include components such as an expansion valve, a compressor, and a control system. The compressor is used to compress low-pressure, low-temperature refrigerant vapor into high-pressure, high-temperature refrigerant vapor to create conditions for condensation at a higher temperature. The control system is used to control the operation of each component.

[0046] The liquid refrigerant in the first evaporator 31 absorbs heat from the liquid in the first path L1, transforming into low-temperature, low-pressure refrigerant vapor. The compressor then performs work on the low-temperature, low-pressure refrigerant vapor, converting it into high-temperature, high-pressure refrigerant vapor. When the high-temperature, high-pressure refrigerant vapor passes through the first condenser 32, it begins to liquefy and release heat, transforming it into low-temperature, high-pressure liquid refrigerant. This refrigerant then passes through the expansion valve to become low-temperature, low-pressure liquid refrigerant. This liquid refrigerant then returns to the first evaporator 31, absorbing heat from the liquid in the first path L1 and transforming into low-temperature, low-pressure refrigerant vapor, thus completing the cycle.

[0047] In order to ensure that the liquid in the pipe between the heating system 1 and the first condenser 32 has enough kinetic energy to circulate, Figure 2 As shown, at least one hot water circulation pump 6 can be provided between the first liquid outlet A2 of the heating system 1 and the liquid inlet D1 of the first condenser. To ensure that the liquid in the pipeline between the cooling system 2 and the first evaporator 31 has sufficient kinetic energy to circulate, at least one cold liquid circulation pump 7 can be provided between the second liquid outlet B2 of the cooling system 2 and the liquid inlet C1 of the first evaporator.

[0048] When the heat demand in the swimming pool is high (e.g. in winter), not only the swimming pool shower equipment and the hot water in the swimming pool need heat, but also the heating equipment needs heat supply. Therefore, in order to ensure normal operation, such as Figure 3 As shown, the air conditioning system may also include a supplementary heat system 4. The pipeline between the supplementary heat system 4 and the heating system 1 constitutes a third path L3. The supplementary heat system 4 has a supplementary heat system liquid inlet E1 and a supplementary heat system liquid outlet E2. The supplementary heat system liquid inlet E1 is connected to the first liquid outlet A2 of the heating system 1, and the supplementary heat system liquid outlet E2 is connected to the first liquid inlet A1 of the heating system. The supplementary heat system 4 is used to provide a heat source to the first liquid inlet A1 of the heating system 1. When the first condenser 32 does not provide enough heat to the heating system 1, the supplementary heat system 4 can be activated to meet the heat demand. The supplementary heat system 4 can be turned on according to the demand in the swimming pool and the liquid flow in the third path L3 can be adjusted accordingly.

[0049] For example, in summer, the cooling demand in the swimming pool is large, and the refrigeration equipment in the swimming pool needs to be cooled. Figure 4 As shown, the cooling system 2 may further include a supplementary cooling system 5. The pipeline between the supplementary cooling system 5 and the cooling system 2 forms a fourth path L4. The supplementary cooling system 5 has a supplementary cooling system liquid inlet F1 and a supplementary cooling system liquid outlet F2. The supplementary cooling system liquid inlet F1 is connected to the second liquid outlet B2 of the cooling system 2, and the supplementary cooling system liquid outlet F2 is connected to the second liquid inlet B1 of the cooling system. The supplementary cooling system 5 is used to provide a cold source to the cooling system 2. When the cooling capacity provided by the first evaporator 31 is insufficient, the supplementary cooling system 5 can be activated to meet the cooling demand. The liquid flow in the fourth path L4 of the supplementary cooling system 5 can be activated and adjusted accordingly according to the demand in the swimming pool.

[0050] The structure of the supplementary cooling system 5 mentioned above is described below with examples. For example, in some embodiments of the present application, Figure 5 As shown, the supplemental cooling system 5 may include at least one refrigeration unit 51 and a cooling tower 52. The refrigeration unit 51 may include a second evaporator 511 and a second condenser 512. The pipeline between the second evaporator 511 and the cooling system 2 constitutes a fourth path L4. The second evaporator 511 has a second evaporator liquid inlet G1 and a second evaporator liquid outlet G2. In this case, the second evaporator liquid inlet G1 is connected to the second liquid outlet B2 of the cooling system 2, and the second evaporator liquid outlet G2 is connected to the second liquid inlet B1 of the cooling system 2. In this way, the second evaporator 511 can cool the liquid in the fourth path L4.

[0051] Furthermore, the pipeline between the cooling tower 52 and the second condenser 512 forms a fifth path L5. The cooling tower 52 has a cooling tower 52 liquid outlet and a cooling tower 52 liquid inlet. The cooling tower 52 liquid outlet is connected to the liquid inlet of the second condenser 512, and the cooling tower 52 liquid inlet is connected to the liquid outlet of the second condenser 512. This allows the cooling tower 52 to remove the heat from the liquefied refrigerant in the second condenser 512, allowing the refrigerant to re-enter the second evaporator 511 for use. The supplemental cooling system 5 also includes a cooling circulation pump 53. This cooling circulation pump 12 is located between the second condenser 512 and the cooling tower 52 liquid outlet to provide kinetic energy for circulation within the fifth path L5.

[0052] The following examples illustrate the temperature parameters associated with the aforementioned cooling tower 52 and refrigeration unit 51. For example, in some embodiments of the present application, in the fourth path L4, the temperature of the cold liquid required by the cooling system 2 is 5°C to 10°C, and the temperature of the cold liquid after use by the cooling system 2 is 10°C to 15°C. Therefore, the temperature of the second evaporator liquid inlet G1 connected to the second liquid outlet B2 of the cooling system is 10°C to 15°C. The inlet temperature of the cooling tower 52 is generally 35°C to 42°C. After cooling in the cooling tower 52, the temperature of the water delivered to the second condenser 512 in the fifth path can be 30°C to 37°C.

[0053] In order to more clearly express the relationship between the above-mentioned temperature parameters, the above-mentioned temperature parameters are partially illustrated below. For example, in some embodiments of the present application, the liquid temperature of the cooling system 2 is 7°C before use, and the liquid temperature rises to 12°C after use. It enters the second evaporator liquid inlet G1 in the fourth path through the second liquid outlet B2 of the cooling system 2. After the second evaporator 511 absorbs heat and cools, the temperature of the second evaporator liquid outlet G2 can be reduced to 7°C, and then transported to the second liquid inlet B1 of the cooling system through the fourth path L4, so as to be recycled again.

[0054] In this case, the liquid in the fourth path L4 cools and transfers heat to the refrigerant liquid in the second evaporator 511. The refrigerant liquid is heated and vaporized, liquefying and releasing heat in the second condenser 512, heating the liquid flowing therein. The outlet temperature of the cooling tower 52 can be 32°C. The liquid in the fifth path L5, after heat transfer in the second condenser 512, can rise to 37°C. Finally, the 37°C liquid is transported by the fifth path L5 to the inlet of the cooling tower 52, where it is cooled to 32°C, thus forming a recycling system.

[0055] For example, the liquid inlet temperature of the second condenser 512 can be 30° C., 32° C., and 37° C., and the liquid outlet temperature of the second condenser 512 can be 35° C., 37° C., and 42° C. The liquid outlet temperature of the cooling tower 52 can be 30° C., 32° C., and 37° C., and the liquid inlet temperature of the cooling tower 52 can be 35° C., 37° C., and 42° C.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
