[0003] Swimming pools need to ensure constant pool water temperature and indoor air comfort. Therefore, in winter, the following are required: first, to heat the pool water to ensure a comfortable water temperature. The national standard is 22-26°C; second, to heat the swimming pool; and third, to dehumidify the air in the swimming pool. In addition, some high-end swimming pools also heat the pool floor so that people can feel comfortable walking on it. The design thermal index of the winter heating load of the swimming pool can reach 180-450W / m 2 The design thermal index of ordinary residential buildings is roughly 30-40W / m 2 , which means that the energy consumption of swimming pools is 5 to 10 times that of ordinary residential buildings. When it is hot in summer, the swimming pool needs to be air-conditioned and the air in the swimming pool needs to be dehumidified. When it is hot, the swimming pool water needs to be cooled. At present, the heating and cooling methods used in traditional swimming pools, such as electric heating, oil boilers or direct use of urban heating networks, not only have high energy consumption, but may also produce a large amount of greenhouse gas emissions. Therefore, the development of an efficient and low-carbon cold and heat source supply system is crucial to reducing the operating costs of swimming pools and reducing the impact on the environment.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0038] The heat pump technology used in this application is a heat "transportation" technology, which can transport the low-temperature heat in groundwater, sewage, and air in the swimming pool to water with a higher temperature, and then use this higher temperature water for heat exchange or heating. Alternatively, the heat with a higher temperature can be transported to groundwater, sewage and air to achieve air conditioning and refrigeration. For swimming pools, based on heat pump technology, the following heat can be recovered in winter: First, the heat in the discharged sewage, which comes from the sewage discharged from the swimming pool or the sewage discharged from the swimming pool water treatment and the sewage discharged from the bathing of customers. Second, the swimming pool needs to discharge the indoor humid air to achieve the purpose of dehumidification, and the heat of the discharged air can be used. The heat from the above two aspects is not enough to support the thermal energy demand of the entire swimming pool. Therefore, combined with the current geothermal energy utilization technology, the ground source heat pump is used to absorb the heat of groundwater to supplement the heat energy of the entire swimming pool. After the air source heat pump unit absorbs heat from the humid air, the air temperature is reduced, and the water can be analyzed out, achieving the purpose of dehumidification while completing the waste heat recovery. Based on the heat pump technology, the operating conditions in summer are opposite to those in winter, that is, the heat pump transfers the heat of the swimming pool water and the air in the swimming pool to the groundwater or sewage, and the heat pump unit generates cold water at 7 to 12°C to achieve the purpose of cooling the pool water and air-conditioning the swimming pool space. In addition, this cold water can be used to cool the humid air in the swimming pool. After the air is cooled, water is analyzed to achieve the purpose of dehumidification, and at the same time, the purpose of cooling the indoor air is also achieved.

In winter, the three heat pump units produce 60℃ hot water, which is supplied to the primary side of the plate heat exchanger 401. After heat exchange, the temperature is reduced to 55℃ and then supplied to the heat pump unit. The secondary side of the plate heat exchanger 401 produces 45℃ hot water, which is supplied to the swimming pool edge floor coil heat exchanger 402, the swimming pool floor coil heat exchanger 403, and the swimming pool air conditioning terminal system 404 to heat the swimming pool edge floor, heat the swimming pool water, and provide air conditioning and heating for the swimming pool.

After the hot and humid air is cooled, the water in the air is analyzed to achieve the purpose of dehumidification.

The underground pipe is a single-loop U-shaped pipe with a common pipe diameter of DN20 / 25 / 32 / 40mm. The material is HDPE (high-density polyethylene), which has good durability and corrosion resistance and can operate stably for a long time.

After leaving the heat pump unit evaporator 1011, the water temperature drops to 9°C. It enters the buried pipe water distributor 1021 through the evaporator outlet pipeline, and then passes through the buried pipe 1022.

[0052] Furthermore, the sewage source heat pump unit 201, in summer operation: the sewage source heat pump unit is in cooling mode, and the function of the heat pump unit is to transfer the heat that needs to be cooled in the swimming pool to the sewage.

[0053] Furthermore, in summer, sewage is supplied to sewage heat exchanger 203 through sewage lifting pump 202, and after heat exchange with working medium water, it is discharged through sewage discharge pipe.
