[0030] like Figures 1 to 4 As shown, the photovoltaic-thermal air handling system of this embodiment includes a photovoltaic heat pump system 1 and an air handling component. The photovoltaic heat pump system 1 includes a photovoltaic module 10 and a heat pump system.

[0031] Air handling units are used to dehumidify and / or regulate the temperature of air. For example, in home or office environments where humidity is a concern, or in the operating environments of equipment that requires low humidity, air handling units dehumidify fresh air. Alternatively, in the aforementioned home, office, or equipment operating environments, air handling units are used to regulate the temperature of air, such as increasing the air temperature or cooling the air to decrease it.

[0032] The heat pump system includes a first heat exchanger connected to a photovoltaic module 10, a compressor 110, a second heat exchanger 112 connected to an air handling unit, a throttling component 113, and a condensate circulating in the system. The condensate exchanges heat with the photovoltaic module 10 in the first heat exchanger and provides heat to the air handling unit in the second heat exchanger 112 to treat the air. After cooling the photovoltaic module in the first heat exchanger, the condensate absorbs heat and is compressed and heated in the compressor. It then provides heat to the air handling unit in the second heat exchanger. The air handling unit uses the heat provided by the condensate in the heat pump system to dehumidify and / or regulate the temperature of the air. The condensate is cooled and depressurized in the second heat exchanger, then further cooled and depressurized by the throttling component 113, before returning to the first heat exchanger to cool the photovoltaic module.

[0033] The air treatment system based on photovoltaic photothermal in the embodiment can cool the photovoltaic module 10 and recover heat through the heat pump system, then transfer the heat to the air for dehumidification and / or temperature adjustment, thereby reducing the working temperature of the photovoltaic module, and achieving dehumidification and / or temperature adjustment of the air by using the photovoltaic heat, and achieving deep and efficient development and utilization of solar energy resources, thereby meeting the dehumidification and / or temperature adjustment requirements of the user.

[0034] In some embodiments, as shown in Figures 1 to 3 The air treatment assembly includes a dehumidification system 2, which includes a dehumidification device 23, a regeneration device 24, and a dehumidification solution circulating between the dehumidification device 23 and the regeneration device 24. The dehumidification solution evaporates water in the regeneration device 24 to change from a dilute solution to a concentrated solution. The dehumidification solution is input into the dehumidification device 23 after changing to a concentrated solution and absorbs moisture from the air in the dehumidification device 23. The dehumidification solution changes from a concentrated solution to a dilute solution in the dehumidification device 23 and is sent to the regeneration device 24. The condensing agent provides heat required for the dehumidification solution to change from a dilute solution to a concentrated solution in the second heat exchange device 112. The solution for dehumidification in the embodiment can be a solution that can achieve its dehumidification function, for example, can be a calcium chloride solution, a potassium chloride solution, a copper sulfate solution, a triethylene glycol solution, a lithium bromide solution, etc. When the air is input into the dehumidification device, the concentrated solution in the dehumidification device absorbs the moisture in the air, and the humidity of the air output from the concentrated solution decreases. While the dehumidification solution absorbs moisture from the air, it can also filter dust in the air to some extent and purify the air. The concentrated solution changes from a concentrated solution to a dilute solution after the dehumidification solution absorbs moisture from the air in the dehumidification device 23, and is then pumped to the regeneration device 24 by the dehumidification pump 25. The heat provided by the condensing agent in the heat pump system evaporates the water to change to a concentrated solution again. After changing to a concentrated solution, the solution on-off valve 26 between the regeneration device 24 and the dehumidification device 23 is opened to reflow into the dehumidification device 23. The dehumidification system in the embodiment can effectively utilize the heat of the condensing agent for dehumidification and achieve good dehumidification effect.

[0035] In some embodiments, as shown in Figure 1 The air treatment assembly includes a dehumidification system 2 and a temperature adjustment system for adjusting the temperature of the air, such as an adsorption refrigeration system 3. The air to be treated is sent into the dehumidification system 2 by the air supply device 41 for dehumidification, then into the temperature adjustment system for temperature adjustment, and then into the user demand area 43. In this process, the photovoltaic heat pump system exchanges heat with the air treatment assembly. Figure 1 The solid arrows in the figure show the flow path of the air, and the dashed arrows show the heat exchange path.

[0036] In some embodiments, as shown in Figure 3As shown, the air treatment assembly includes a first air supply device for sending a part of the air to be dehumidified into the regenerating device 24 to take away the moisture evaporated by the dehumidification solution, and a second air supply device for sending the remaining part of the air to be dehumidified into the dehumidification device 23 to be dehumidified. In the embodiment as shown, the first air supply device includes a first air supply fan 221, and the second air supply device includes a second air supply fan 222. By dividing the air to be dehumidified into two parts, the embodiment can accelerate the moisture evaporation process of the dehumidification solution in the regenerating device 24, and improve the speed and effect of the dehumidification solution becoming a concentrated solution in the regenerating device, thereby helping to improve the dehumidification effect on the air.

[0037] In some embodiments, as shown in Figure 3 the first air supply device includes a first air supply duct in communication with the cavity of the regenerating device 24 containing the dehumidification solution, and the first air supply duct is used to make the air flow from the surface of the dehumidification solution in the regenerating device 24, and the second air supply device includes a second air supply duct in communication with the cavity of the dehumidification device 23 containing the dehumidification solution, and the second air supply duct is used to make the air pass through the inside of the concentrated solution. The first air supply device can more effectively and quickly take away the moisture evaporated by the dehumidification solution by sending the air to flow from the surface of the dehumidification solution, further improving the moisture evaporation efficiency of the dehumidification solution. The second air supply duct sends the air to be dehumidified into the concentrated solution in the dehumidification device 23, so that the air is effectively dehumidified.

[0038] In some embodiments, as shown in Figure 1 and Figure 3 the air treatment assembly further includes a humidity detection device 40 for detecting the humidity of the air, and a third air supply device for directly sending the air without passing through the dehumidification device 23 and without passing through the regenerating device 24. In the embodiment as shown in Figure 2 the air treatment assembly includes a humidity detection shunt device 21, which includes the humidity detection device 40 and a multi-way valve, and the humidity detection shunt device 21 controls the opening and closing of the multi-way valve according to the detection result of the humidity detection device 40 to send the air into different passages. The third air supply device includes a third fan 223, and when the air is sent in, such as fresh air, the humidity detection device first detects the humidity of the air, and when the humidity of the air is not high, the third air supply device directly sends out without dehumidification. The directly sent air is directly sent to the user end, or is sent to the user end after being tempered by a temperature adjusting device such as a refrigeration device. The embodiment can detect the humidity of the air, and can flexibly judge whether to dehumidify the air according to the detection result, and can flexibly process the air according to the different humidity of the air.

[0039] In some embodiments, the air treatment assembly comprises a dehumidification system and a refrigeration air conditioning system, such as an adsorption refrigeration system 3, and the air is dehumidified by the dehumidification system before being refrigerated by the refrigeration air conditioning system, which avoids the adverse phenomenon of condensate water on the working surface of the evaporator of the refrigeration air conditioning system under high humidity air and the adverse effects caused thereby, while achieving efficient use of energy.

[0040] In some embodiments, as shown in Figure 3 , the condensing agent cools the dehumidification device 23 in the first heat exchange device. Figure 3 In the embodiment shown, the arrows with solid lines indicate the air flow path, the arrows with double-dot dashed lines indicate the condensing agent flow path, and the arrows with dashed lines indicate the dehumidification solution flow path. The dehumidification device generates heat when dehumidifying the air, and the condensing agent is arranged to cool the dehumidification device, which can improve the dehumidification effect of the dehumidification device on the air.

[0041] In some embodiments, the first heat exchange device comprises a heat exchange pipe passing through the cavity of the dehumidification device 23 containing the dehumidification solution and isolated from the dehumidification solution of the dehumidification device 23, and the condensing agent cools the dehumidification device 23 through the heat exchange pipe. The condensing agent exchanges heat with the dehumidification device by passing through the heat exchange pipe of the dehumidification device, which can improve the heat exchange effect with the dehumidification device and further improve the dehumidification effect of the dehumidification device.

[0042] In some embodiments, as shown in Figure 2 and Figure 3 , a hot water circulation system is further included, and the condensing agent exchanges heat with the hot water circulation system in the second heat exchange device 112 and provides heat to the air treatment assembly through the hot water circulation system. In Figure 2 the embodiment shown, the dashed lines indicate the hot water flow path of the hot water circulation system, and in Figure 3 the embodiment shown, the arrows with dot-dashed lines indicate the hot water flow path of the hot water circulation system. In this embodiment, the condensing agent first exchanges heat with the hot water circulation system in the second heat exchange device, transferring heat to the hot water circulation system, and then the hot water circulation system exchanges heat with the air treatment assembly to transfer the heat provided by the condensing agent to the air treatment assembly. The hot water circulation system can flexibly arrange the hot water flow path to provide heat to multiple locations, which can make the heat transfer of the condensing agent more flexible and variable, and facilitate flexible arrangement. In some embodiments, the hot water circulation system comprises a hot water circulation pipeline and a hot water pump.

[0043] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 4As shown, the air treatment assembly comprises an adsorption refrigeration system 3, the adsorption refrigeration system 3 comprises an evaporation chamber 34 and an adsorption chamber connected with the hot water circulation system, the evaporation chamber 34 is used for water evaporation to exchange heat with the air passing through the evaporation chamber 34 to cool the air, the adsorption chamber is used for adsorbing water vapor and desorbing water vapor, and the condensing agent provides heat to the adsorption chamber when the water vapor is desorbed. The air passes through the evaporation chamber through the pipeline arranged through the evaporation chamber, the cooling water evaporates in the evaporation chamber 34 to cool the air passing through the evaporation chamber, and the air is output to the user end after the temperature is lowered after passing through the evaporation chamber. The adsorption chamber is provided with silica gel and other adsorption materials to absorb the water vapor cooled by the air, and then the adsorption chamber sends the adsorbed water vapor to the condensing chamber through the heat provided by the condensing agent, and the water vapor is condensed into cooling water in the condensing chamber, and then is sent to the evaporation chamber to cool the air. Through the arrangement of the adsorption refrigeration system 3, the heat of the photovoltaic assembly can be used to effectively cool the air, and the heat of the photovoltaic assembly can be deeply utilized.

[0044] In some embodiments, the adsorption refrigeration system further comprises a condensing chamber 33 connected with the adsorption chamber, the condensing chamber 33 is connected with the first heat exchange device, and the condensing agent passes through the condensing chamber 33 through the first heat exchange device to cool the water vapor transported from the adsorption chamber to the condensing chamber 33. By arranging the pipeline through the condensing chamber 33 through the condensing agent, the condensing agent can be used to effectively cool the water vapor in the condensing chamber 33, the effective use of the condensing agent is realized, and after the condensing agent absorbs the heat of the water vapor, the heat is transferred to the air treatment assembly through the second heat exchange device, and the heat is transferred and efficiently utilized.

[0045] In some embodiments, the adsorption refrigeration system further comprises a condensing chamber 33 connected with the adsorption chamber, the condensing chamber 33 is connected with the first heat exchange device, and the condensing agent passes through the condensing chamber 33 through the first heat exchange device to cool the water vapor transported from the adsorption chamber to the condensing chamber 33. By arranging the pipeline through the condensing chamber 33 through the condensing agent, the condensing agent can be used to effectively cool the water vapor in the condensing chamber 33, the effective use of the condensing agent is realized, and after the condensing agent absorbs the heat of the water vapor, the heat is transferred to the air treatment assembly through the second heat exchange device, and the heat is transferred and efficiently utilized. Figure 4In the shown embodiment, the adsorption chambers include a first adsorption chamber 31 and a second adsorption chamber 32, and the air flow path is shown by the dashed arrows. The adsorption refrigeration system mainly includes the following steps: Step 1): preheating of the first adsorption chamber and precooling of the second adsorption chamber: the hot water generated by the hot water circulation system after heat exchange through the second heat exchange device flows through the eleventh three-way valve V11, the seventh three-way valve V7, the first adsorption chamber, the ninth three-way valve V9 and the thirteenth three-way valve V10, until the pressure of the first adsorption chamber is no longer lower than the pressure in the condensation chamber. The condensate of the heat pump system flows through the condensation chamber, the sixth three-way valve V6, the second adsorption chamber and the eighth three-way valve V8 to cool the second adsorption chamber until its pressure is no longer higher than the evaporation pressure. At this stage, the eleventh three-way valve V11, the tenth two-way valve V12 and the fourteenth three-way valve V14 are all closed, and the system does not generate cold. Step 2): desorption of the first adsorption chamber and adsorption of the second adsorption chamber: open the first two-way valve V1 and the fourth two-way valve V4, and the first adsorption chamber and the second adsorption chamber operate in desorption and adsorption modes respectively. After the water vapor from the third two-way valve V3 flows into the first adsorption chamber and is adsorbed, the hot water enters the first adsorption chamber to heat, and the desorbed water vapor flows into the condensation chamber through the first two-way valve V1, condenses into saturated water in the condensation chamber, and then forms low-enthalpy wet saturated vapor after pressure reduction and temperature reduction through the throttling element V5 and flows into the evaporation chamber. At the same time, fresh air also flows into the evaporation chamber, and the low-enthalpy wet saturated vapor absorbs heat and forms low-temperature and low-humidity fresh air to meet the customer's demand. The saturated vapor evaporated is adsorbed by the second adsorption chamber, and the condensate provided by the photovoltaic photothermal heat pump system carries away the heat generated by the condensation chamber and the second adsorption chamber. Step 3): mass return process from the first adsorption chamber to the second adsorption chamber: when step 2 reaches the critical value, the throttling element V5 is opened. Because there is a pressure gradient between the first adsorption chamber and the second adsorption chamber, when the throttling element V5 is opened, a mass return process from the first adsorption chamber to the second adsorption chamber occurs, thereby increasing the circulating adsorption amount. Step 4): heat return process from the first adsorption chamber to the second adsorption chamber. After the mass return process continues for a period of time, the throttling element V5 is closed. The condensate continuously flows through the condensation chamber, the sixth three-way valve V6, the first adsorption chamber, the ninth three-way valve V9, the thirteenth three-way valve V10, the seventh three-way valve V7, the second adsorption chamber and the eighth three-way valve V8. The heat of the first adsorption chamber is transferred to the second adsorption chamber, and the heat return cycle is completed.
