[0033] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 3 As shown, this example provides a multifunctional energy-saving system, which includes a rotary dehumidifier, an air conditioning unit 2, a heat pump 3, a chiller 4, a water tank 5, a hot water pump 6, a cooling water pump 7 and a refrigeration water pump 8; wherein the heat pump 3 includes an evaporator 31, which is arranged in the water tank 5; the rotary dehumidifier includes a dehumidifier surface cooler 13 and a regeneration air heating component 14, and the air conditioning unit 2 includes an air conditioning surface cooler 21 and an air conditioning supply air heating component 22; the hot water pump 6 is connected to the heat pump 3, the regeneration air heating component 14 and the air conditioning supply air heating component 22 respectively, and the hot water pump 6 is connected to the heat pump 3, the regeneration air heating component 14 and the air conditioning supply air heating component 22 respectively. It is used to pump hot water to the regeneration air heating component 14 and the air conditioning supply air heating component 22 to release heat, and the hot water after heat exchange flows back to the heat pump 3; the cooling water pump 7 is connected to the water tank 5 and the chiller 4 respectively, and the cooling water pump 7 is used to pump the cooling water in the water tank 5 to the chiller 4 for heat release and then flow back to the water tank 5, and the chilled water pump 8 is connected to the chiller 4, the dehumidifier surface cooler 13, and the air conditioning surface cooler 21 respectively. The chilled water pump 8 is used to pump the chilled water to the dehumidifier surface cooler 13 and the air conditioning surface cooler 21 to absorb heat, and the chilled water after heat exchange flows back to the chiller 4.

[0035] In this example, the rotary dehumidifier and the air-conditioning unit 2 can work simultaneously or not. Therefore, the opening and closing of each pipeline can be controlled by setting valves to ensure that hot water and chilled water flow to the working components to work, thereby avoiding energy waste.

[0036] The multifunctional energy-saving system includes a cooling water circulation loop A, a chilled water circulation loop B and a hot water circulation loop C. The cooling water circulation loop A is composed of a water tank 5, a cooling water pump 7 and a part of the heat exchange components of the chiller 4; the chilled water circulation loop B is composed of another part of the heat exchange components of the chiller 4, the dehumidifier surface cooler 13 and / or the air conditioning surface cooler 21 and the chilled water pump 8; the hot water circulation loop C is composed of a part of the heat exchange components of the heat pump 3 except the evaporator 31, the regeneration air heating component 14 and / or the air conditioning supply air heating component 22 and the hot water pump 6.

[0037] In this example, the water tank 5 includes a accommodating chamber 51 that can accommodate the evaporator 31 and cooling water. The evaporator 31 is located in the accommodating chamber 51 and is immersed in the cooling water. For example, the heat exchange part of the evaporator 31 can be completely immersed in the cooling water. The heat pump 3 and the chiller 4 are arranged in parallel; the heat pump 3, the chiller 4, the water tank 5, the hot water pump 6, the cooling water pump 7 and the chilled water pump 8 are all located next to the rotary dehumidifier or the air-conditioning unit 2, and on the same side.

[0038] The utility model places the evaporator 31 of the heat pump 3 in the water tank 5 to cool the cooling water of the chiller 4, eliminating the conventional cooling tower. The hot water side of the heat pump 3 sends the hot water to the rotary dehumidifier for regeneration air heating and supply air heating through the hot water pump 6, and can also be sent to the air conditioning unit 2 for supply air heating.

[0039] Implementation method: start the cooling water pump 7, the chilled water pump 8, and the hot water pump 6. When the water flow reaches the startup requirement, start the chiller 4 and the heat pump 3. The chilled water is sent to the rotary dehumidifier and the air-conditioning unit 2 for cooling through the chilled water pump 8; the evaporator 31 of the heat pump 3 absorbs the heat of the cooling water in the water tank 5, so that the cooling water in the water tank 5 can be cooled and cooled. The cooled water flows back to the chiller 4, and the hot water generated by the heat pump 3 is sent to the rotary dehumidifier for regeneration heating and air supply heating through the hot water pump 6, and is also sent to the air supply heating of the air-conditioning unit 2. In this way, the evaporator 31 of the heat pump 3 is used to reduce the temperature of the cooling water and make rational use of the hot water generated by the heat pump 3. The energy consumption of the rotary dehumidifier and the air-conditioning unit is greatly reduced, and the energy consumption of the entire system is greatly reduced.

[0040] Furthermore, in this example, the rotary dehumidifier may be a single-rotor dehumidifier 11 and / or a double-rotor dehumidifier 12. For example, a single-rotor dehumidifier 11 and a double-rotor dehumidifier 12 may be provided in the system at the same time.

[0041] Further, see Figure 1 and Figure 2As shown, the single-rotor dehumidifier 11 includes a single-rotor fresh air channel 111, a single-rotor regeneration air channel 112, and a coarse-effect filter 113, a front surface cooling section 114, a medium-efficiency filter 115, a medium surface cooling section 116, a dehumidification zone 117a of the dehumidification rotor, a blower 118a, an air supply filter 119c, a rear surface cooling section 119a, and an air supply heating section 119b arranged in sequence along the single-rotor fresh air channel 111; and a regeneration air heating assembly 14, a regeneration zone 117b of the dehumidification rotor, and a regeneration blower 118b arranged in sequence along the single-rotor regeneration air channel 112.

[0042] The front surface cooling section 114, the middle surface cooling section 116 and the rear surface cooling section 119a are respectively independently provided with a dehumidifier surface cooler 13, and the air supply heating section 119b is provided with a dehumidifier air supply heating component 15, which is respectively connected to the hot water pump 6 and the heat pump 3.

[0043] Further, see Figure 1 and Figure 3 As shown, the dual-rotor dehumidifier 12 includes a dual-rotor fresh air channel 121, a dual-rotor regeneration air channel 122, and a coarse-effect filter 123, a front surface cooling section 124, a dehumidification zone 125a of a first dehumidification rotor, a first blower 126, a medium-efficiency filter 127, a medium surface cooling section 128, a dehumidification zone 129a of a second dehumidification rotor, a second blower 130, and an air heating section 131, which are sequentially arranged along the dual-rotor regeneration air channel 122; and a regeneration air heating assembly 14, a regeneration zone 129b of the second dehumidification rotor, a regeneration zone 125b of the first dehumidification rotor, and a regeneration blower 132, which are sequentially arranged along the dual-rotor regeneration air channel 122.

[0044] The front surface cooling section 124 and the middle surface cooling section 128 are respectively independently provided with a dehumidifier surface cooler 13, and the air supply heating section 131 is provided with a dehumidifier air supply heating component 15, which is connected to the hot water pump 6 and the heat pump 3 respectively.

[0045] During the operation of the dehumidification wheel, the fresh air is filtered and removed of impurities by the filter in the fresh air channel, cooled by the surface cooler, and sent to the dehumidification area of the dehumidification wheel for dehumidification. It is then heated or not heated as needed and sent to indoor or other required places; and the regenerated air is heated by the regeneration air heating component and sent to the regeneration area of the dehumidification wheel to regenerate the dehumidification wheel so that it can circulate and dehumidify. In this process, the cooling and heat required by the surface cooler and heating component can come from the energy-saving system itself, and there is no need to set up additional electric heating or steam heating equipment.

[0046] In summary, the present invention is based on the fact that the existing air-conditioning boxes and rotary dehumidifiers have high energy consumption during use, and cooling towers must be used for heat dissipation, which causes the cooling towers to be relatively dirty and must be cleaned regularly. The cleaning cost is high and the cleaning time is long. Otherwise, the performance of the cold water system will be unstable. Based on a lot of practice, the inventors of the present invention innovatively combine the air-conditioning unit, the rotary dehumidifier and the heat pump, especially adding a water tank and placing the evaporator of the heat pump in the water tank, so that the energy-saving system of the present invention can use the heat absorbed by the evaporator during operation to cool the water in the water tank, and then can be used as a cold source for the chiller to cool the chilled water. The chilled water can then be used by the rotary dehumidifier and the surface cooler of the air-conditioning box, thereby improving the performance of the rotary dehumidifier. The dehumidification efficiency of the dehumidifier and the cooling efficiency of the air-conditioning unit, etc., and the heat pump can also supply hot water at the same time. The hot water can also be supplied to the regeneration air heating of the rotary dehumidifier or the rear heating of the supply air, and can also be supplied to the supply air heating of the air-conditioning unit. That is, in the present invention, the heat absorbed and released by the heat pump during the heat exchange process comes from or is used for the system itself, so that energy is reasonably utilized to the maximum extent, thereby reducing the energy consumption of the rotary dehumidifier and the air-conditioning unit, and can also omit the cooling tower that must be used in the existing chiller. After the use of the cooling tower, the utility model does not need to perform regular cleaning and other processes, thereby reducing the cost of use, especially it can achieve continuous operation (must be shut down for cleaning), which greatly improves performance.
