For swimming comfort, swimming pools are equipped with air supply, cooling and heating systems. As people's requirements for green buildings and venues' energy consumption become increasingly stringent, energy consumption has become one of the important evaluation indicators of swimming pool facilities. In related technologies, in order to improve the comfort and economy of swimming pools, the air treatment of swimming pools no longer uses a separate fresh air system, a separate heating system and a separate cooling system, but integrates the above-mentioned independent systems, integrating the three functions of swimming pool water heating, pool room air dehumidification and indoor air conditioning into the heat pump system. The general integrated heat pump system is based on the traditional refrigeration system. The condenser is installed outdoors. The indoor air needs to be heated by the condenser, and the dry hot air is sent out to warm the indoor air. The pipeline design is complicated, which is not conducive to the layout of the air supply equipment.

The heat pump system 1 provided in an embodiment of the present application includes an evaporation component 30, an air supply component 40, a condensation component 10, a detection component and a control component 50. The air supply component 40 is used to supply air to a swimming pool. The condensation component 10 is arranged in the swimming pool, and the condensation component 10 includes at least two condensers. Each of the condensers has at least one of the following functions: used to condense the working medium in the heat pump system 1, used to exchange heat with the air supply component 40, and used to heat the swimming pool.

[0034] The first preset range may correspond to a scenario in which the room temperature or ambient temperature is high in seasons such as spring and summer, for example, the detection component detects that the room temperature is greater than or equal to 20°C-25°C. The second preset range may correspond to a scenario in which the room temperature or ambient temperature is high in seasons such as autumn and winter, for example, the detection component detects that the room temperature is less than 10°C-20°C.

[0035] The above-mentioned heat pump system 1 arranges the condensing component 10 indoors, and the evaporating component 30 and the condensing component 10 are directly involved in the dehumidification and heating of the air supply component 40 and the heating of the swimming pool. The system pipeline layout is more convenient and the system integration degree is high. At the same time, by detecting environmental parameters, the current season is determined, and then the working conditions of the air supply component 40 and the condenser are controlled. The corresponding condenser is activated according to the corresponding season, so that the air supply component 40 supplies air to pass through the corresponding condenser to work, and will not pass through the non-working condenser, thereby reducing the wind resistance in the system, reducing the overall system energy consumption, being more environmentally friendly, improving the air supply and heat exchange efficiency, and improving the operating economy of the venue facilities.

[0036] In one embodiment, the first environmental parameter includes a carbon dioxide concentration parameter and a room temperature parameter of the swimming pool. The carbon dioxide concentration parameter is used to control the start and stop of the air supply component 40.

[0038] When the carbon dioxide concentration parameter in the first environmental parameter exceeds the standard value, the control component 50 controls the air volume of the fresh air circuit and the exhaust air circuit 2 to increase, reduces or stops the air volume of the return air entering the mixed air circuit 3, and reduces or closes the air volume of the mixed air circuit 3; when the carbon dioxide concentration parameter in the first environmental parameter is less than or equal to the standard value, the control component 50 controls the air volume of the fresh air circuit, the mixed air circuit 3 and the exhaust air circuit 2 to maintain a dynamic balance.

[0039] The air supply component 40 also includes an air supply port, an air exhaust port, a first fan 41 and a second fan 42. The outlet of the first fan 41 is connected to the air supply port, the inlet of the first fan 41 is connected to the proximal end of the fresh air circuit and the proximal end of the mixed air circuit 3, the distal end of the fresh air circuit is connected to the outdoors, and the distal end of the mixed air circuit 3 is provided with multiple branches, and the multiple branches are respectively heat exchanged through different condensers, and each branch is provided with a corresponding valve to control the opening or closing of the branch. The proximal end of the fresh air circuit and the proximal end of the mixed air circuit 3 are respectively provided with a fresh air valve and a mixed air valve, and the control component 50 controls the air volume of each circuit by controlling the opening size of the fresh air valve and the mixed air valve. The proximal end of the exhaust circuit 2 is connected to the fresh air circuit and / or the mixed air circuit 3, and the distal end of the exhaust circuit 2 is connected to the exhaust port through the second fan 42. The proximal end of the exhaust circuit 2 is provided with an exhaust valve, and the control component 50 controls the air volume of the exhaust circuit 2 by controlling the opening size of the exhaust valve or controlling the working power of the second fan 42. A portion of the indoor return air is discharged from the exhaust port by the second fan 42, and a portion is mixed with the fresh air and enters the mixed air circuit 3 after passing through the mixed air valve.

[0040] In one embodiment, the heat pump system 1 further includes a compressor 20, the detection component is used to detect a second environmental parameter of the evaporation component 30, and the control component 50 is used to control the operation of the compressor 20 and the evaporation component 30 according to the second environmental parameter. The second environmental parameter includes the inlet humidity and the outlet humidity of the evaporation component 30, and the first environmental parameter includes the indoor humidity parameter of the swimming pool; when the indoor humidity parameter and the outlet humidity are both within a third preset range, the control component 50 controls the compressor 20 to stop working; when the indoor humidity parameter and the outlet humidity exceed the third preset range, the control component 50 controls the compressor 20 to work so that the evaporation component 30 works.

[0041] The detection component includes a first temperature detector 51, a second temperature detector 52, a third temperature detector (not shown), a first humidity detector 53, a second humidity detector 54, and a third humidity detector 55. The first temperature detector 51 is used to detect the temperature at the inlet of the mixed air circuit 3, the second temperature detector 52 is used to detect the temperature at the outlet of the first fan 41, and the third temperature detector is used to detect room temperature parameters. The first humidity detector 53 is used to detect the humidity at the inlet of the mixed air circuit 3, the second temperature detector 52 is used to detect the humidity of the condenser, and the third humidity detector 55 is used to detect the humidity of the evaporation component 30.

[0042] Specifically, the working fluid absorbs heat through the evaporation component 30 and changes from a low-pressure, low-temperature liquid to a low-pressure, low-temperature gas. The heat of the gas passing through the evaporation component 30 is absorbed and then liquefied. When the indoor humidity parameter and the outlet humidity both meet the third preset range, the control component 50 controls the compressor 20 to stop working. On the one hand, the overall cooling and heating work of the heat pump system 1 meets the requirements, and on the other hand, the humidity is controlled not to exceed the preset range.

[0043] In one embodiment, the condensation component 10 includes a first condenser 11 and a second condenser 12, the circuit of the air supply component 40 passes through the first condenser 11 to exchange heat with the working medium, the second condenser 12 is connected to the water circuit of the swimming pool, and the control component 50 can control the second condenser 12 to heat the swimming pool, and can enable the first condenser 11 to heat the air supply of the air supply component 40.

[0044] The condensation component 10 includes a third condenser 13. When the first environmental parameter reaches a first preset range, the third condenser 13 is connected to an external first water source. When the first environmental parameter reaches a second preset range, the third condenser 13 is connected to an external second water source, and the control component 50 can enable the first condenser 11 and / or the third condenser 13 to cool or heat the air supply of the air supply component 40. The third condenser 13 is used to achieve heat exchange of the working fluid. When the working fluid has excess heat that cannot be fully exchanged through the first and second condensers 12, the control component 50 controls the activation of the third condenser 13. The condensation component 10 can also include a fourth condenser, a fifth condenser, etc., which are used to exchange heat for the supply air.

[0045] When the first environmental parameter reaches the second preset range, the control component 50 controls the second condenser 12 to heat the swimming pool, and at least activates the first condenser 11 to heat the air supply of the air supply component 40, and activates at least one of the second condenser 12 and the third condenser 13 to perform its corresponding function to heat the air supply of the air supply component 40. Further, the first environmental parameter also includes a third preset range and a fourth preset range. When the first environmental parameter reaches the first preset range, the evaporation component 30 is first started for dehumidification, and the control component 50 then determines whether the first environmental parameter meets the third preset range. If not, the first condenser 11 is activated (or the pipeline where it is located is opened to allow the air supply to pass through) to heat the air supply. When the first environmental parameter reaches the second preset range, the evaporation component 30 is first started for dehumidification and the first condenser 11 is activated (or the pipeline where it is located is opened to allow the air supply to pass through) to heat the air supply. The control component 50 then determines whether the first environmental parameter meets the fourth preset range. If not, the third condenser 13 is activated (or the pipeline where it is located is opened to allow the air supply to pass through) to heat the air supply again.

[0046] In summer, when the air supply temperature does not meet the requirements, the first condenser 11 can be activated to heat the air supply circuit and heat the swimming pool. In winter, at least one condenser is activated to heat the air supply circuit to ensure the heating of the air supply. The first condenser 11 is always open, and the third condenser 13 can be selectively activated. The temperature of the first water source is lower than the room temperature, and the temperature of the second water source is higher than the temperature of the first water source, and higher than the room temperature parameters at that time, to ensure the heating efficiency of the third condenser 13.

[0047] Further, in the direction from the second fan 42 to the first fan 41, the evaporation component 30, the first condenser 11 and the third condenser 13 are sequentially arranged in the pipeline of the mixed air circuit 3, the evaporation component 30 is arranged on the main road of the mixed air circuit 3, and the supply air first passes through the evaporation component 30 for dehumidification. The main road is connected with a first branch and a second branch connected in parallel, the first condenser 11 is arranged on the main road of the mixed air circuit 3 or on the first branch after the main road, the third condenser 13 is arranged on the first branch, and the condenser is not arranged on the second branch. When the condenser and the supply air are not required to participate in heat exchange, it can be switched to the second branch to reduce the system loop wind resistance. It can be understood that the second condenser 12 does not participate in the heat exchange of the supply air and can be not arranged in the pipeline of the mixed air circuit 3. Specifically, the heat pump system 1 also includes a valve system, and the valve system includes a first electric valve 14, a second electric valve 15, a third electric valve 16, a first electric air valve, a second electric air valve and a third electric air valve. The first electric valve 14, the second electric valve 15 and the third electric valve 16 correspond to the inlet pipeline settings of the first condenser 11, the second condenser 12 and the third condenser 13 respectively. When the corresponding condenser is not needed to be activated, the control component 50 controls the corresponding electric valve to close to prevent the working medium from entering. The first electric air valve and the second electric air valve correspond to the inlet pipeline settings of the first condenser 11 and the second condenser 12 respectively. When the corresponding condenser is not needed to be activated to participate in heat exchange, the control component 50 controls the corresponding electric air valve to close to prevent the supply air from entering to increase the overall wind resistance of the system.

[0048] The working principle of the working medium, air and water circuit of the heat pump system 1 of this embodiment is as follows. The first fan 41 draws air from the outdoor of the swimming pool as fresh air into the fresh air circuit, and the warm and humid air in the swimming pool and the air after heat exchange in the condensing component 10 enter the mixed air circuit 3 as return air. The second fan 42 at the end of the exhaust circuit 2 is used to exhaust air and form a negative pressure in the circuit. The control component 50 selects the air volume of the corresponding circuit as needed. The air flowing through the evaporation component 30 transfers heat energy to the cold liquid refrigerant while cooling and dehumidifying. This energy exchange reduces the air temperature to below the dew point, converts the humid air passing through the evaporation component 30 into dry cold air, and dehumidifies and cools the supply air. After the liquid working medium flows through the evaporation component 30, it becomes a low-temperature and low-pressure gaseous working medium. The low-temperature gaseous refrigerant then enters the compressor 20 and is compressed into a high-temperature gaseous state. The control component 50 controls the operation of the compressor 20 according to the evaporation component 30 and the indoor humidity. The high-temperature gaseous refrigerant flows through the first condenser 11, the second condenser 12 and / or the third condenser 13, and the high-temperature gaseous refrigerant is transformed from gas to liquid, releasing the recovered heat. The air side or water side of the first condenser 11, the second condenser 12 and / or the third condenser 13 absorbs the heat released by the working fluid, and then heats the indoor air or the pool water. If the indoor air temperature reaches the requirement, the recovered condensation heat can also be used to heat the pool water, and dry cold air is sent out to cool the indoor air. If the indoor air temperature and the pool water temperature both reach the requirements, the recovered condensation heat is discharged to the outdoor atmosphere through the outdoor condenser.
