Description

Technical Field

[0001] This utility model relates to the field of cold and heat source supply technology, specifically to a multi-functional dehumidifying hot and cold water unit, which is suitable for places such as the swimming pool industry or the pharmaceutical purification industry that require both cold and heat sources. Background Technology

[0002] Current methods for dehumidifying swimming pools typically involve dehumidifiers or integrated pool heat pumps. Dehumidifiers lack hot water functionality. While integrated heat pumps offer hot water recovery, their systems are complex and prone to instability. In winter, when hot water is needed, only the heating and dehumidification mode can be used, requiring additional heat sources for auxiliary heating. In summer, heat needs to be released into the air. This results in bloated system configurations and low machine utilization.

[0003] Due to the special nature of the swimming pool industry, a large number of air source heat pumps are required to heat the pool water and shower water. The cold energy generated in this process is discharged externally, which is a huge waste in summer. In winter, because the dehumidification capacity is less than in summer, and the three-in-one unit must first cool and dehumidify before heating, the heat of the unit is far from enough in winter, and additional heat sources are needed for auxiliary heating.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1:

[0036] like Figure 1 As shown, this utility model provides a multifunctional dehumidification hot and cold water unit, which mainly includes a water production component, a first air chamber 14, and a second air chamber 15.

[0037] The water purification assembly includes a compressor 1, with its outlet connected to a reversing valve 3. The reversing valve 3's return port is connected back to the compressor 1's return port. The two outlets of the reversing valve 3 are respectively connected to one end of a water-cooled heat exchanger 2 and an air-cooled heat exchanger 5. The ends of the water-cooled heat exchanger 2 and the air-cooled heat exchanger 5 not connected to the reversing valve 3 are interconnected, and an electronic expansion valve 4 is installed in the connecting pipeline between the water-cooled heat exchanger 2 and the air-cooled heat exchanger 5. The reversing valve 3 is used to change the flow direction of the refrigerant in this refrigerant system. By controlling the reversing valve 3, the refrigerant flowing from the compressor 1 can directly enter the water-cooled heat exchanger 2 or directly enter the air-cooled heat exchanger 5, thus switching between hot water and cold water modes.

[0038] An air-cooled heat exchanger 5 is installed inside the first air chamber 14, dividing the first air chamber 14 into a left air cavity 141 and a right air cavity 142, so that the airflow in the left air cavity 141 must pass through the air-cooled heat exchanger 5 to enter the right air cavity 142. A fresh air valve 6 and a return air valve 17, which communicate with the left air cavity 141, are respectively installed on the side wall of the first air chamber 14 for controllable airflow into the left air cavity 141. An exhaust valve 10, which communicates with the right air cavity 142, is installed on the side wall of the first air chamber 14 for controllable exhaust of the airflow from the right air cavity 142.

[0039] The air supply valve 9 is connected between the right first air chamber 142 and the left second air chamber 151, and can control the opening and closing of the air passage between the right first air chamber 142 and the left second air chamber 151.

[0040] The surface cooler finned heat exchanger 11 is installed inside the second air chamber 15, dividing the second air chamber 15 into a left second air chamber 151 and a right second air chamber 152. This ensures that the airflow in the left second air chamber 151 passes through the surface cooler finned heat exchanger 11 before entering the right second air chamber 152. A return air valve II8, communicating with the left second air chamber 151, is installed on the side wall of the second air chamber 15 for controllable airflow into the left second air chamber 151. An air outlet 17 is located on the side wall of the second air chamber 15, communicating with the right second air chamber 152. A dehumidifying fan 13 is installed in the right second air chamber 152 to discharge airflow from within the right second air chamber 152.

[0041] Example 2:

[0042] Based on the above embodiment one, as follows Figure 1 As shown, the third air chamber 16 and the second air chamber 15 are closely attached to one side of the first air chamber 14, with the second air chamber 15 stacked on top of the third air chamber 16. The exhaust valve 10 connects the right air chamber 142 and the third air chamber 16, controlling whether the air passage between them is open. An exhaust port 18 is located on the third air chamber 16, and a heat exchange fan 12 is installed in the third air chamber 16 to deliver airflow from within it.

[0043] On the other side of the first air chamber 14, adjacent to it, is an equipment installation chamber 19. The compressor 1, the reversing valve 3 and the water-cooled heat exchanger 2 are installed in the equipment installation chamber 19. The inlet pipe and outlet pipe of the water-cooled heat exchanger 2 pass through the equipment installation chamber 19.

[0044] Example 3:

[0045] Based on the above embodiment two, as follows Figures 1 to 4 As shown, in use, the outlet of the water pump assembly 20 is connected to the inlet of the water-cooled heat exchanger 2. The inlet of the water pump assembly 20 is connected to the outlet of the air conditioning water tank 25 via electric valve III 23. The inlet of the water pump assembly 20 is also connected to the outlet of the hot water tank 26 via electric valve IV 24. The outlet of the water-cooled heat exchanger 2 is connected to the return outlet of the hot water tank 26 via electric valve II 22. The outlet of the water-cooled heat exchanger 2 is also connected to the inlet of the surface cooler finned heat exchanger 11 via electric valve I 21. The return outlet of the surface cooler finned heat exchanger 11 is connected to the air conditioning water tank 25.

[0046] The air inlet of the air-conditioned space 27, which requires temperature regulation, is connected to the air outlet 17 via a pipe. The return air outlet of the air-conditioned space 27 is connected to the return air valve I7 and the return air valve II8 via pipes. The return air pipe of the air-conditioned space 27 can be controlled through the return air valve I7 and the return air valve II8.
