Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly to an air conditioning system and an automobile applying the air conditioning system. Background Art

[0002] An automobile air conditioning system generally has three working modes: refrigeration, heating, and ventilation. During operation, fresh air needs to be introduced from the outside. In the cold winter, the outdoor ambient temperature is very low. Therefore, the temperature of the fresh air inhaled by the air conditioner from the outside is also very low, resulting in too low suction temperature and suction pressure of the compressor, making it difficult for the air conditioning system to quickly enter the working state and resulting in a slow heating rate; in the hot summer, the outdoor ambient temperature is very high. Therefore, the temperature of the fresh air inhaled by the air conditioner from the outside is also very high, resulting in too high inlet temperature and inlet pressure of the expansion valve, making it difficult for the air conditioning system to quickly enter the working state and resulting in a slow cooling rate; thus, passengers stay in an extremely cold or extremely hot environment for a long time, affecting the user's riding experience.

[0040] However, during the actual working process, especially in extremely cold or hot seasons, it often affects the operation of the evaporator and condenser in the air-conditioning system, reducing their working efficiency. This causes the air-conditioning system to be difficult to quickly enter the working state, resulting in a slower cooling or heating rate. As a result, the time for the vehicle interior temperature to reach a comfortable temperature becomes longer, prolonging the waiting time of passengers and affecting the riding experience of users. Therefore, a circulation system is set up to recycle the gas passing through the first heat exchange air duct or the second heat exchange air duct. Thus, within a certain period after the air-conditioning system is just started, the inlet air temperature of the evaporator is increased or the inlet air temperature of the condenser is decreased, thereby promoting the air-conditioning system to quickly enter the working state. The circulation system includes a first circulation air duct and a second circulation air duct. The first circulation air duct is connected to the first heat exchange air duct, used to recycle the gas after heat exchange through the first heat exchange air duct, and circulate and transport it to the first air inlet and / or the third air inlet. The second circulation air duct is connected to the second heat exchange air duct, used to recycle the gas after heat exchange through the second heat exchange air duct, and circulate and transport it to the first air inlet and / or the third air inlet. By respectively controlling the on-off of the first circulation air duct and the second circulation air duct, and correspondingly adjusting the opening and blocking of the first air inlet, the second air inlet, the third air inlet, the fourth air inlet, the first air outlet, the second air outlet, the third air outlet, the fourth air outlet, and the circulation air inlet, the gas heated by the condenser is recycled into the second heat exchange air duct, increasing the temperature of the gas entering the second heat exchange air duct, assisting the evaporator in heat exchange, and promoting the air-conditioning gas to quickly enter the working state; or the gas cooled by the evaporator is recycled into the first heat exchange air duct, decreasing the temperature of the gas entering the first heat exchange air duct, thereby assisting the condenser in heat exchange and promoting the air-conditioning gas to quickly enter the working state. Thus, the time required for the vehicle interior temperature to reach a comfortable temperature is reduced, the waiting time of passengers is reduced, and the riding experience of users is improved.

[0058] The present invention provides an air conditioning system.

[0059] In the embodiments of the present invention, as Figures 1 to 9 shown, the air conditioning system includes a first heat exchange air duct 10, a second heat exchange air duct 30, and a circulation system. The first heat exchange air duct 10 is internally provided with a condenser 11, and the first heat exchange air duct 10 has a first air inlet end 12 and a first air outlet end 13. The first air inlet end 12 includes a first air inlet 121 communicating with the circulating air inlet 20 inside the vehicle and a second air inlet 122 communicating with the outside of the vehicle. The first air outlet end 13 communicates with a first air outlet 131 inside the vehicle and a second air outlet 132 communicating with the outside of the vehicle respectively. The second heat exchange air duct 30 is internally provided with an evaporator 31, and the second heat exchange air duct 30 has a second air inlet end 32 and a second air outlet end 33. The second air inlet end 32 includes a third air inlet 321 communicating with the circulating air inlet 20 and a fourth air inlet 322 communicating with the outside of the vehicle. The second air outlet end 33 communicates with a third air outlet 331 inside the vehicle and a fourth air outlet 332 communicating with the outside of the vehicle respectively. The circulation system includes a first circulation air duct 40 and a second circulation air duct 50. The first circulation air duct 40 communicates with the first heat exchange air duct 10 and is used to recover the gas after heat exchange through the first heat exchange air duct 10 and circulate and transport it to the first air inlet 121 and / or the third air inlet 321. The second circulation air duct 50 communicates with the second heat exchange air duct 30 and is used to recover the gas after heat exchange through the second heat exchange air duct 30 and circulate and transport it to the first air inlet 121 and / or the third air inlet 321.

[0060] Specifically, this air conditioning system is applied to an automobile. A circulating air inlet 20 is provided on the automobile body, and the circulating air inlet 20 communicates with the first air inlet 121 and the third air inlet 321. A condenser 11 is provided in the first heat exchange air duct 10. The condenser 11 heats up the gas in the first heat exchange air duct 10. Therefore, in the heating mode, the condenser 11 serves as the in-vehicle unit. The fresh air formed after the outside air passes through the automobile air filtration system enters the first heat exchange air duct 10 through the second air inlet 122. The gas heated by the first heat exchange air duct 10 passes through the first air outlet end 13 and is discharged into the vehicle interior through the first air outlet 131 to warm up the vehicle interior. The evaporator 31 serves as the out-of-vehicle unit. The fresh air formed after the outside air passes through the automobile air filtration system enters the second heat exchange air duct 30 through the fourth air inlet 322. The gas cooled by the second heat exchange air duct 30 passes through the second air outlet end 33 and is discharged out of the vehicle through the fourth air outlet 332. In this way, the gas flow direction in the heating mode is completed to warm up the vehicle interior. It should be noted that the "communication" expressed in the present invention only indicates the connection relationship between different ventilation ducts and does not represent its communication state. Whether it is actually communicated is controlled by its corresponding control switch or whether each air duct is blocked. For example, among the first air outlet end 13 communicating with the first air outlet 131 in the vehicle interior and the second air outlet 132 communicating with the outside of the vehicle, the first air outlet end 13 can be only communicated with the first air outlet 131, or only communicated with the second air outlet 132, or simultaneously communicated with the first air outlet 131 and the second air outlet 132. And the first air outlet end 13 described in this embodiment refers to a section of air duct from the position after the condenser 11 to before the first air outlet 131 and the second air outlet 132. And the meaning of the first air outlet end 13 communicating with the first air outlet 131 and the second air outlet 132 respectively can be: the first air outlet end 13 directly communicates with the first air outlet 131 and the second air outlet 132, that is, the first air outlet 131 and the second air outlet 132 are directly opened at the end of the first air outlet end 13 away from the condenser 11; or, the first air outlet end 13 is indirectly connected to the first air outlet 131 and the second air outlet 132, such as the first air outlet end 13 is respectively connected to the first air outlet 131 and the second air outlet 132 through a preset air duct.

[0061] The evaporator 31 is located inside the second heat exchange air duct 30. The evaporator 31 cools the gas in the second heat exchange air duct 30. Therefore, in the cooling mode, the evaporator 31 serves as the in-vehicle unit. The fresh air formed after the outside air passes through the automotive air filtration system enters the second heat exchange air duct 30 through the fourth air inlet 322. The gas cooled by the second heat exchange air duct 30 passes through the second air outlet end 33 and is discharged into the vehicle through the third air outlet 331 to cool the vehicle interior; while the condenser 11 serves as the out-of-vehicle unit. The fresh air formed after the outside air passes through the automotive air filtration system enters the first heat exchange air duct 10 through the second air inlet 122. The gas heated by the second heat exchange air duct 30 is discharged outside the vehicle through the second air outlet 132 on the first air outlet end 13. Thus, the gas flow direction in the cooling mode is completed to cool the vehicle interior. In this embodiment, the second air outlet end 33 refers to a section of the air duct from the position where the evaporator 31 is located to before the third air outlet 331 and the fourth air outlet 332. And the meaning that the second air outlet end 33 is respectively connected to the third air outlet 331 and the fourth air outlet 332 can be: the second air outlet end 33 is directly connected to the third air outlet 331 and the fourth air outlet 332, that is, the third air outlet 331 and the fourth air outlet 332 are directly opened at the second air outlet end 33; or, the second air outlet end 33 is indirectly connected to the third air outlet 331 and the fourth air outlet 332, such as the second air outlet end 33 is respectively connected to the third air outlet 331 and the fourth air outlet 332 through a preset air duct.

[0062] However, in the actual working process, especially in extremely cold or hot seasons, such as in the cold winter, the outdoor ambient temperature is very low. Therefore, the temperature of the fresh air inhaled by the first heat exchange air duct 10 from the outside is also very low, which may cause the suction temperature and suction pressure of the compressor to be too low, not conducive to the heat exchange of the condenser 11, resulting in the air conditioning system being difficult to quickly enter the working state and the heating rate becoming slower; while in the hot summer, the outdoor ambient temperature is very high. Therefore, the temperature of the fresh air inhaled by the air conditioning system from the outside is also very high, resulting in the inlet temperature and inlet pressure of the expansion valve being too high, not conducive to the heat exchange of the evaporator 31, resulting in the air conditioning system being difficult to quickly enter the working state and the cooling rate being slower. This makes the time for the vehicle interior temperature to become a comfortable temperature longer, prolonging the waiting time of passengers and affecting the riding experience of users. Therefore, a circulation system is set up to recycle the gas passing through the first heat exchange air duct 10 or the second heat exchange air duct 30, so as to increase the inlet temperature of the evaporator 31 or decrease the inlet temperature of the condenser 11 within a period of time when the air conditioning system is just started, thereby promoting the air conditioning system to quickly enter the working state.

[0063] The circulation system includes a first circulation air duct 40 and a second circulation air duct 50. The circulation air inlet 20 is communicated with the first air inlet 121 and the third air inlet 321 through a connecting passage, and the third air outlet end 402 of the first circulation air duct 40 and the fourth air outlet end 502 of the second circulation air duct 50 are both communicated with this connecting passage. Thus, the gas heated by the condenser 11 is recovered into the second heat exchange air duct 30 to increase the temperature of the gas entering the second heat exchange air duct 30, thereby assisting the evaporator 31 in heat exchange and promoting the air-conditioning system to quickly enter the working state; or the gas cooled by the evaporator 31 is recovered into the first heat exchange air duct 10 to reduce the temperature of the gas entering the first heat exchange air duct 10, thereby assisting the condenser 11 in heat exchange and promoting the air-conditioning system to quickly enter the working state. By controlling the on-off of the first circulation air duct 40 and the on-off of the second circulation air duct 50, the switching of different working modes or states of the air-conditioning system is adapted. Moreover, the opening and blocking of the first air inlet 121, the second air inlet 122, the third air inlet 321, the fourth air inlet 322, the first air outlet 131, the second air outlet 132, the third air outlet 331, the fourth air outlet 332, and the circulation air inlet 20 can all be correspondingly adjusted according to the switching of different working modes or states of the air-conditioning system.

[0064] The technical solution of the present invention realizes the normal operation of the air-conditioning system in the heating mode and the cooling mode and the mutual switching between the two, and ensures the normal operation of the air-conditioning system by controlling the opening and blocking of the first air inlet 121, the second air inlet 122, the third air inlet 321, the fourth air inlet 322, the first air outlet 131, the second air outlet 132, the third air outlet 331, the fourth air outlet 332, and the circulation air inlet 20. The first heat exchange air duct 10 and the second heat exchange air duct 30 are provided. The first heat exchange air duct 10 is internally provided with a condenser 11, and the first heat exchange air duct 10 has a first air inlet end 12 and a first air outlet end 13. The first air inlet end 12 includes a first air inlet 121 communicated with the circulation air inlet 20 inside the vehicle and a second air inlet 122 communicated with the outside of the vehicle. The first air outlet end 13 is respectively communicated with a first air outlet 131 inside the vehicle and a second air outlet 132 outside the vehicle. The second heat exchange air duct 30 is internally provided with an evaporator 31, and the second heat exchange air duct 30 has a second air inlet end 32 and a second air outlet end 33. The second air inlet end 32 includes a third air inlet 321 communicated with the circulation air inlet 20 and a fourth air inlet 322 communicated with the outside of the vehicle. The second air outlet end 33 is respectively communicated with a third air outlet 331 inside the vehicle and a fourth air outlet 332 outside the vehicle.

[0065] However, in the actual working process, especially in extremely cold or hot seasons, it often affects the operation of the evaporator 31 and the condenser 11 in the air conditioning system, reducing their working efficiency. This causes the air conditioning system to be difficult to quickly enter the working state, resulting in a slower cooling or heating rate. As a result, the time taken for the vehicle interior temperature to reach a comfortable temperature becomes longer, prolonging the waiting time of passengers and affecting the riding experience of users. Therefore, a circulation system is set up to recycle the gas passing through the first heat exchange air duct 10 or the second heat exchange air duct 30. Thus, within a certain period of time when the air conditioning system is just started, the inlet air temperature of the evaporator 31 is increased or the inlet air temperature of the condenser 11 is decreased, thereby promoting the air conditioning system to quickly enter the working state. This circulation system includes a first circulation air duct 40 and a second circulation air duct 50. The first circulation air duct 40 is connected to the first heat exchange air duct 10, used to recycle the gas after heat exchange through the first heat exchange air duct 10, and circulate and transport it to the first air inlet 121 and / or the third air inlet 321. The second circulation air duct 50 is connected to the second heat exchange air duct 30, used to recycle the gas after heat exchange through the second heat exchange air duct 30, and circulate and transport it to the first air inlet 121 and / or the third air inlet 321. By respectively controlling the on-off of the first circulation air duct 40 and the second circulation air duct 50, and correspondingly adjusting the opening and blocking of the first air inlet 121, the second air inlet 122, the third air inlet 321, the fourth air inlet 322, the first air outlet 131, the second air outlet 132, the third air outlet 331, the fourth air outlet 332, and the circulation air inlet 20, the gas heated by the condenser 11 is recycled into the second heat exchange air duct 30, increasing the temperature of the gas entering the second heat exchange air duct 30, assisting the evaporator 31 in heat exchange, and promoting the air conditioning gas to quickly enter the working state; or the gas cooled by the evaporator 31 is recycled into the first heat exchange air duct 10, decreasing the temperature of the gas entering the first heat exchange air duct 10, thereby assisting the condenser 11 in heat exchange and promoting the air conditioning gas to quickly enter the working state. Thereby reducing the time required for the vehicle interior temperature to reach a comfortable temperature, reducing the waiting time of passengers, and improving the riding experience of users.

[0066] Refer to Figure 1 、 Figure 5 and Figure 9In one embodiment, the air conditioning system has a heating mode, and the heating mode has a first heating state. In the first heating state, the first air inlet 121, the second air inlet 122, the third air inlet 321, the fourth air outlet 332 and the first circulation air duct 40 are all connected, and the circulation air inlet 20, the first air outlet 131, the second air outlet 132, the third air outlet 331, the fourth air inlet 322 and the second circulation air duct 50 are all blocked, so that the gas outside the vehicle enters the first heat exchange air duct 10 for heat exchange and passes through the first circulation air duct 40. After that, part of the gas enters the first air inlet 121 to continue to circulate, and the other part of the gas passes through the third air inlet 321 and flows into the second heat exchange air duct 30 for heat exchange and is discharged outside the vehicle. Specifically, the fresh air outside the vehicle enters the first heat exchange air duct 10 from the second air inlet 122, and after being heated by the condenser 11, enters the first circulation air duct 40 from the third air inlet end 401. The third air outlet end 402 of the first circulation air duct 40 is connected to both the first air inlet 121 and the third air inlet 321, so that a part of the gas enters from the first air inlet 121 and flows into the first heat exchange air duct 10 after being neutralized with the fresh air entering from the second air inlet 122, thereby neutralizing and increasing the inlet temperature of the fresh air, thereby increasing the inlet temperature of the first heat exchange air duct 10, reducing heat waste, and thereby reducing the power required for the condenser 11 to work. The other part flows into the second heat exchange air duct 30 from the third air inlet 321 for heat exchange, thereby increasing the inlet temperature of the second heat exchange air duct 30, and the evaporator 31 recovers waste heat, thereby increasing the suction temperature and suction pressure of the compressor, assisting the evaporator 31 in heat exchange, and helping the air conditioning system to quickly enter the working state.

[0067] In another embodiment, the air conditioning system has a heating mode, and the heating mode has a first heating state. In the first heating state, the second air inlet 122, the third air inlet 321, the fourth air outlet 332 and the first circulation air duct 40 are all turned on, and the circulating air inlet 20, the first air inlet 121, the first air outlet 131, the second air outlet 132, the third air outlet 331, the fourth air inlet 322 and the second circulation air duct 50 are all blocked, so that the gas outside the vehicle enters the first heat exchange duct 10 for heat exchange and passes through the first circulation air duct 40. After that, the gas enters the third air inlet 321 and flows into the second heat exchange duct 30 for heat exchange and is discharged outside the vehicle. That is, the first air inlet 121 is blocked. At this time, the third air outlet 402 of the first circulation air duct 40 is only connected to the third air inlet 321, so that the gas heated by the condenser 11 in the first heat exchange air duct 10 all flows into the second heat exchange air duct 30 from the third air inlet 321 to assist the evaporator 31 in heat exchange.

[0068] Reference Figure 2 and Figure 6Furthermore, the heating mode also has a second heating state. The first heating state can be switched to the second heating state. In the second heating state, the circulating air inlet 20, the first air inlet 121, the second air inlet 122, the fourth air inlet 322, the first air outlet 131 and the fourth air outlet 332 are all connected, and the third air inlet 321, the second air outlet 132, the third air outlet 331, the first circulation air duct 40 and the second circulation air duct 50 are all blocked, so that the gas after heat exchange through the first heat exchange duct 10 is discharged into the vehicle and circulated to the first heat exchange duct 10 again together with the gas in the vehicle. Specifically, after the air-conditioning system has been working for a period of time and the evaporator 31 enters the working state normally, the circulating air inlet 20, the fourth air inlet 322, and the first air outlet 131 are adjusted to be opened, and the third air inlet 321 and the second air outlet 132 are closed, and the first circulating air duct 40 is blocked, and the first heating state is switched to the second heating state, so that the fresh air outside the vehicle enters the first heat exchange duct 10 from the second air inlet 122, and the gas heated by the condenser 11 flows into the vehicle from the first air outlet 131. After the temperature in the vehicle is raised, it flows into the first air inlet 121 again from the circulating air inlet 20, so that the gas is neutralized with the fresh air entering from the second air inlet 122 and flows into the first heat exchange duct 10 together, thereby neutralizing and increasing the inlet temperature of the fresh air, and then increasing the inlet temperature of the first heat exchange duct 10, reducing heat waste, and reducing the power required for the condenser 11 to work. In addition, fresh air outside the vehicle enters the second heat exchange air duct 30 through the fourth air inlet 322 , and the evaporator 31 normally works and exchanges heat, and then discharges the gas through the fourth air outlet 332 .

[0069] Reference Figure 3 and Figure 7 In one embodiment, the air conditioning system also has a cooling mode, and the cooling mode has a first cooling state. In the first cooling state, the first air inlet 121, the fourth air inlet 322, the second air outlet 132 and the second circulation air duct 50 are all connected, and the circulating air inlet 20, the second air inlet 122, the third air inlet 321, the first air outlet 131, the third air outlet 331, the fourth air outlet 332 and the first circulation air duct 40 are all blocked, so that the gas outside the vehicle enters the second heat exchange air duct 30 for heat exchange, and flows from the second circulation air duct 50 into the first heat exchange air duct 10 for heat exchange and is discharged outside the vehicle. Specifically, fresh air outside the vehicle enters the second heat exchange duct 30 through the fourth air inlet 322, and after being cooled by the evaporator 31, enters the second circulation duct 50 through the fourth air inlet end 501. The second circulation duct 50 is connected to the first air inlet 121, so that the gas flows into the first heat exchange duct 10 from the first air inlet 121, thereby reducing the air inlet temperature of the first heat exchange duct 10, and then reducing the inlet temperature and inlet pressure of the expansion valve, assisting the condenser 11 in heat exchange, and helping the air-conditioning system to quickly enter the working state.

[0070] Reference Figure 4 and Figure 8Furthermore, the cooling mode also has a second cooling state. The first cooling state can be switched to the second cooling state. In the second cooling state, the circulating air inlet 20, the first air inlet 121, the second air inlet 122, the third air inlet 321, the second air outlet 132 and the third air outlet 331 are all connected, and the fourth air inlet 322, the first air outlet 131, the fourth air outlet 332, the first circulating air duct 40 and the second circulating air duct 50 are all blocked, so that the gas after heat exchange through the second heat exchange air duct 30 is discharged into the vehicle, passes through the circulating air inlet 20, and then a part enters the third air inlet 321 to continue circulating, and the other part is discharged outside the vehicle after heat exchange in the first heat exchange air duct 10 through the first air inlet 121. Specifically, after the air conditioning system has been working for a period of time, the evaporator 31 and the condenser 11 are in normal working state, the circulating air inlet 20, the first air inlet 121, the second air inlet 122, the third air inlet 321, the second air outlet 132 and the third air outlet 331 are opened, the fourth air inlet 322, the first air outlet 131 and the fourth air outlet 332 are closed, and the first circulating air duct 40 and the second circulating air duct 50 are blocked, and the first cooling state is switched to the second cooling state, so that the gas cooled by the evaporator 31 flows into the vehicle from the third air outlet 331 to cool the vehicle, and a part of the gas flows into the vehicle from the circulating air inlet 20 again. The third air inlet 321 then flows into the second heat exchange duct 30, thereby lowering the working temperature of the fresh air, and then lowering the air inlet temperature of the second heat exchange duct 30, reducing energy waste, and reducing the power required for the evaporator 31 to work; another part of the gas flows into the first air inlet 121 from the circulating air inlet 20, and then flows into the first heat exchange duct 10, and then flows into the first heat exchange duct 10 together with the fresh air flowing in from the second air inlet 122, thereby lowering the temperature of the gas entering the first heat exchange duct 10, so that the condenser 11 is always in a state of high energy utilization, thereby reducing the power loss of the air-conditioning system, and then discharged out of the vehicle through the second air outlet 132.

[0071] In another embodiment, the cooling mode also has a second cooling state, and the first cooling state can be switched to the second cooling state. In the second cooling state, the circulating air inlet 20, the second air inlet 122, the third air inlet 321, the second air outlet 132 and the third air outlet 331 are all connected, and the first air inlet 121, the fourth air inlet 322, the first air outlet 131, the fourth air outlet 332, the first circulating air duct 40 and the second circulating air duct 50 are all blocked, so that the gas after heat exchange through the second heat exchange air duct 30 is discharged into the vehicle, passes through the circulating air inlet 20, and then enters the third air inlet 321 to continue to circulate. That is, the first air inlet 121 is blocked, and at this time, the fourth air outlet end 502 of the second circulating air duct 50 is only connected to the third air inlet 321, so that the gas after cooling through the evaporator 31 all flows from the third air inlet 321 into the second heat exchange air duct 30 to assist the evaporator 31 in heat exchange.

[0072] Referring to Figure 2 and Figure 6 In one embodiment, a first control valve 60 for controlling the on-off of the third air inlet 321 and the first air inlet 121 is provided between the third air inlet 321 and the first air inlet 121. The first control valve 60 has a first switching position 601, a second switching position 602, and a third switching position 603 that can be mutually converted;

[0073] At the first switching position 601, the first air inlet 121 is opened and the third air inlet 321 is closed; at the second switching position 602, the third air inlet 321 is opened and the first air inlet 121 is closed; at the third switching position 603, both the third air inlet 321 and the first air inlet 121 are opened, and the first control valve 60 controls the air inlet ratio of the third air inlet 321 and the first air inlet 121.

[0074] Specifically, the first control valve 60 controls the mutual conversion of the first switching position 601, the second switching position 602, and the third switching position 603, thereby controlling the opening and closing of the first air inlet 121 and the third air inlet 321, and further controlling the connection and closing of the first circulation air duct 40 and the second circulation air duct 50 with the first air inlet 121 and / or the third air inlet 321, so as to realize the conversion under different states and / or different modes of the air conditioning system. And because the first control valve 60 is a stepless control valve, that is, the first switching valve 60 can rotate to any position between the first switching position 601, the second switching position 602, and the third switching position 603, the first control valve 60 can also control the air inlet ratio of the third air inlet 321 and the first air inlet 121, thereby controlling the gas recovery amount of the second heat exchange air duct 30 and the first heat exchange air duct 10, and further controlling the temperature of the gas in the second heat exchange air duct 30 and the first heat exchange air duct 10. Among them, the first control valve 60 can control the air inlet ratio of the third air inlet 321 and the first air inlet 121 by its deflection angle relative to the first air inlet 121 and the third air inlet 321, and further control the diameters of the first air inlet 121 and the third air inlet 321. Compared with using multiple control valves to control the opening and closing of the first air inlet 121 and the third air inlet 321, this solution is more convenient to install and operate.

[0075] Combined with reference to Figure 1 、 Figures 3 to 5 、 Figures 7 to 9, in another embodiment, a first switching valve group 61 is provided between the third air inlet 321 and the first air inlet 121. The first switching valve group 61 includes a first switching valve 611 for controlling the on / off of the first air inlet 121 and a second switching valve 612 for controlling the on / off of the third air inlet 321, and the first switching valve group 61 controls the air inlet ratio between the third air inlet 321 and the first air inlet 121. Specifically, since both the first switching valve 611 and the second switching valve 612 are stepless control valves, by rotating the inclination angles of the first switching valve 611 and the second switching valve 612, the aperture sizes of the first air inlet 121 and the second air inlet are controlled, and then the air inlet ratio between the first air inlet 121 and the third air inlet 321 is controlled. Furthermore, compared with using a single control valve to control the air inlet ratio of the first air inlet 121 and the third air inlet 321 at the same time, this solution can more accurately control the air inlet ratio of the first air inlet 121 and the third air inlet 321.

[0076] With reference to Figure 9 , in one embodiment, the first circulation air duct 40 has a third air inlet end 401 and a third air outlet end 402. The third air inlet end 401 is directly connected to the first heat exchange air duct 10 and is located before the first air outlet 131 and the second air outlet 132. The third air outlet end 402 communicates with the first air inlet 121 and / or the third air inlet 321. Specifically, the third air inlet end 401 of the first circulation air duct 40 is directly connected to the first heat exchange air duct 10 and is located before the first air outlet 131 and the second air outlet 132, that is, the third air inlet end 401 is connected to a section of the air duct after the position of the condenser 11 in the first heat exchange air duct 10. If the first air outlet end 13 is directly connected to the first air outlet 131 and the second air outlet 132, then the third air inlet end 401 is connected after the position of the condenser 11 and before the first air outlet 131 and the second air outlet 132; if the first air outlet end 13 is indirectly connected to the first air outlet 131 and the second air outlet 132, then the third air inlet end 401 is connected after the position of the condenser 11 and before the air duct connecting the first air outlet end 13 and the first air outlet 131 and the air duct connecting the first air outlet end 13 and the second air outlet 132; so that in the first heating state, the gas after heat exchange via the first heat exchange air duct 10 directly flows into the first circulation air duct 40, thereby shortening the air flow path and further reducing heat loss.

[0077] Further, first control switches 62 are provided at the first circulating air duct 40, the first air outlet 131, and the second air outlet 132. The three first control switches 62 respectively control the on / off of the first circulating air duct 40, the first air outlet 131, and the second air outlet 132, and respectively control the air intake volume and the air intake rate of the first circulating air duct 40, the first air outlet 131, and the second air outlet 132. That is, when the third air intake end 401 of the first circulating air duct 40 is directly connected to the first heat exchange air duct 10 and is located before the first air outlet 131 and the second air outlet 132, a first control switch 62 is provided at each of the first circulating air duct 40, the first air outlet 131, and the second air outlet 132. The three first control switches 62 respectively control their on / off, thereby determining the gas flow direction. And the first control switch 62 is also an infinitely variable control valve, so as to adjust the air intake volume and the air intake rate of the first circulating air duct 40, the first air outlet 131, and the second air outlet 132.

[0078] When the third air intake end 401 of the first circulating air duct 40 is directly connected to the first heat exchange air duct 10 and is located before the first air outlet 131 and the second air outlet 132, in another embodiment, the second circulating air duct 50 has a fourth air intake end 501 and a fourth air outlet end 502. The fourth air intake end 501 is directly connected to the second heat exchange air duct 30 and is located before the third air outlet 331 and the fourth air outlet 332. The fourth air outlet end 502 communicates with the first air intake port 121 and / or the third air intake port 321. Specifically, the fourth air intake end 501 of the second circulating air duct 50 is directly connected to the second heat exchange air duct 30 and is located before the third air outlet 331 and the fourth air outlet 332, that is, the fourth air intake end 501 is connected to a section of the air duct after the position where the evaporator 31 is located in the second heat exchange air duct 30. If the second air outlet end 33 is directly connected to the third air outlet 331 and the fourth air outlet 332, then the fourth air intake end 501 is connected after the position where the evaporator 31 is located and before the first air outlet 131 and the second air outlet 132; if the second air outlet end 33 is indirectly connected to the third air outlet 331 and the fourth air outlet 332, then the fourth air intake end 501 is connected after the position where the evaporator 31 is located and before the air duct connecting the second air outlet end 33 and the third air outlet 331 and the air duct connecting the second air outlet end 33 and the fourth air outlet 332; so that in the first cooling state, the gas heat-exchanged through the second heat exchange air duct 30 directly flows into the second circulating air duct 50, thereby shortening the air flow path and further reducing energy loss.

[0079] Further, second control switches 621 are provided at the second circulation air duct 50, the third air outlet 331, and the fourth air outlet 332. The three second control switches 621 respectively control the on / off of the second circulation air duct 50, the third air outlet 331, and the fourth air outlet 332, and control the air intake volume and air intake rate of the second circulation air duct 50, the third air outlet 331, and the fourth air outlet 332. That is, when the fourth air intake end 501 of the second circulation air duct 50 is directly connected to the second heat exchange air duct 30 and is located before the third air outlet 331 and the fourth air outlet 332, a second control switch 621 is provided at each of the second circulation air duct 50, the third air outlet 331, and the fourth air outlet 332. The three second control switches 621 respectively control their on / off, thereby determining the gas flow direction. Moreover, the second control switches 621 are also all stepless control valves, so as to adjust the air intake volume and air intake rate of the second circulation air duct 50, the third air outlet 331, and the fourth air outlet 332.

[0080] With reference to Figures 1 to 8 , in an embodiment, the air conditioning system further includes a first shunt duct 133 and a second shunt duct 134 communicating with the first air outlet end 13. The first shunt duct 133 communicates with the first air outlet 131, and the second shunt duct 134 communicates with the second air outlet 132. The first circulation air duct 40 has a third air intake end 401 and a third air outlet end 402. The third air intake end 401 is connected to the second shunt duct 134, and the third air outlet end 402 communicates with the first air intake port 121 and / or the third air intake port 321. Specifically, the air conditioning system further includes a first shunt duct 133 and a second shunt duct 134 communicating with the first air outlet end 13, and both the first shunt duct 133 and the second shunt duct 134 communicate with the first air outlet end 13. That is, at the first air outlet end 13, the air duct bifurcates to form the first shunt duct 133 and the second shunt duct 134. The first air outlet 131 is provided on the first shunt duct 133, and the second air outlet 132 is provided on the second shunt duct 134. The third air intake end 401 is connected to the second shunt duct 134. That is, the third air intake end 401 is connected after the first air outlet end 13, so that the gas heated by the first heat exchange air duct 10 flows through the first air outlet end 13 into the second shunt duct 134, and then enters the first circulation air duct 40 for circulation through the third air intake end 401.

[0081] In another embodiment, the air conditioning system further includes a third shunt passage 333 and a fourth shunt passage 334 that communicate with the second air outlet end 33. The third shunt passage 333 communicates with the third air outlet 331, and the fourth shunt passage 334 communicates with the fourth air outlet 332. The second circulation air duct 50 has a fourth air inlet end 501 and a fourth air outlet end 502. The fourth air inlet end 501 is connected to the fourth shunt passage 334, and the fourth air outlet end 502 communicates with the first air inlet 121 and / or the third air inlet 321. Specifically, the air conditioning system further includes a third shunt passage 333 and a fourth shunt passage 334 that communicate with the second air outlet end 33, and both the third shunt passage 333 and the fourth shunt passage 334 communicate with the second air outlet end 33. That is, the air duct bifurcates at the second air outlet end 33 to form the third shunt passage 333 and the fourth shunt passage 334. The third air outlet 331 is provided in the third shunt passage 333, and the fourth air outlet 332 is provided in the fourth shunt passage 334. The fourth air inlet end 501 is connected to the fourth shunt passage 334. That is, the fourth air inlet end 501 is connected after the second air outlet end 33, so that the gas after heat exchange through the second heat exchange air duct 30 flows into the fourth shunt passage 334 through the second air outlet end 33, and then enters the second circulation air duct 50 through the fourth air inlet end 501 for circulation.

[0082] With reference to Figures 5 to 8 , in one embodiment, a second switching valve group 14 is provided at the first shunt passage 133 and the second shunt passage 134. The second switching valve group 14 includes a third switching valve 141 provided in the first shunt passage 133 and a fourth switching valve 142 provided in the second shunt passage 134, and the second switching valve group 14 controls the air inlet ratio of the first shunt passage 133 and the second shunt passage 134. Specifically, the first shunt passage 133 is controlled by the third switching valve 141, and the second shunt passage 134 is controlled by the fourth switching valve 142, so as to control the flow direction of the gas. Since both the third switching valve 141 and the fourth switching valve 142 are stepless control valves, by rotating the inclination angles of the third switching valve 141 and the fourth switching valve 142, the opening sizes of the first shunt passage 133 and the second shunt passage 134 are controlled, and then the air inlet ratio of the first shunt passage 133 and the second shunt passage 134 is controlled. Compared with using one control valve to control the air inlet ratio of the first shunt passage 133 and the second shunt passage 134 at the same time, this solution can more accurately control the air inlet ratio of the first shunt passage 133 and the second shunt passage 134.

[0083] In another embodiment, with reference to Figures 1 to 4 , a second control valve 15 is provided at the connection between the first shunt passage 133 and the second shunt passage. The second control valve 15 has a fourth switching position 151 and a fifth switching position 152 that can be switched with each other, and the second control valve 15 controls the air inlet ratio of the first shunt passage 133 and the second shunt passage 134;

[0084] In the fourth switching position 151 , the second branch flow channel 134 is conducting, and the first branch flow channel 133 is blocked; in the fifth switching position 152 , the first branch flow channel 133 is conducting, and the second branch flow channel 134 is blocked.

[0085] Specifically, the second control valve 15 controls the mutual conversion between the fourth switching position 151 and the fifth switching position 152, thereby controlling the conduction and blocking of the first branch channel 133 and the second branch channel 134, thereby controlling the flow direction of the gas. And because the second control valve 15 is a stepless control valve, that is, the second control valve 15 can rotate at any position between the fourth switching position 151 and the fifth switching position 152, the fourth switching position 151 and the fifth switching position 152 in this solution are both the positions of the second control valve 15 in the extreme state. Therefore, the second control valve 15 can also control the air intake ratio of the first branch channel 133 and the second branch channel 134. Among them, the second control valve 15 can control the opening size of the first branch channel 133 and the second branch channel 134 by its deflection angle relative to the first branch channel 133 and the second branch channel 134, and then control the air intake ratio of the first branch channel 133 and the second branch channel 134. Compared with using multiple control valves to control the conduction and blocking of the first branch channel 133 and the second branch channel 134, this solution is more convenient to install and more convenient to operate.

[0086] Combined with reference Figures 5 to 8 In one embodiment, a third switching valve group 34 is provided at the third branch channel 333 and the fourth branch channel 334, and the third switching valve group 34 includes a fifth switching valve 341 provided in the fourth branch channel 334 and a sixth switching valve 342 provided in the third branch channel 333, and the third switching valve group 34 controls the air intake ratio of the third branch channel 333 and the fourth branch channel 334. Specifically, the third branch channel 333 is controlled by the sixth switching valve 342, and the fourth branch channel 334 is controlled by the fifth switching valve 341, so as to control the flow direction of the gas. Since the fifth switching valve 341 and the sixth switching valve 342 are both stepless control valves, the opening sizes of the fourth branch channel 334 and the third branch channel 333 are controlled by rotating the inclination angles of the fifth switching valve 341 and the sixth switching valve 342, thereby controlling the air intake ratio of the fourth branch channel 334 to the third branch channel 333. Compared with using one control valve to simultaneously control the air intake ratio of the third branch channel 333 and the fourth branch channel 334, this solution can more accurately control the air intake ratio of the third branch channel 333 and the fourth branch channel 334.

[0087] In another embodiment, in conjunction with reference Figures 1 to 4 A third control valve 35 is provided at the connection between the third branch flow channel 333 and the fourth branch flow channel 334. The third control valve 35 has a sixth switching position 351 and a seventh switching position 352 that switch between each other, and the third control valve 35 controls the air intake ratio of the third branch flow channel 333 and the fourth branch flow channel 334;

[0088] In the seventh switching position 352 , the fourth branch flow channel 334 is conducting, and the third branch flow channel 333 is blocked; in the sixth switching position 351 , the third branch flow channel 333 is conducting, and the fourth branch flow channel 334 is blocked.

[0089] Specifically, the third control valve 35 controls the conduction and blocking of the third branch channel 333 and the fourth branch channel 334 by controlling the mutual conversion between the sixth switching position 351 and the seventh switching position 352, thereby controlling the flow direction of the gas. And because the third control valve 35 is a stepless control valve, that is, the third control valve 35 can rotate at any position between the sixth switching position 351 and the seventh switching position 352, the sixth switching position 351 and the seventh switching position 352 in this solution are both the positions of the third control valve 35 in the extreme state. Therefore, the third control valve 35 can also control the air intake ratio of the third branch channel 333 and the fourth branch channel 334. Among them, the third control valve 35 can control the opening size of the third branch channel 333 and the fourth branch channel 334 by its deflection angle relative to the third branch channel 333 and the fourth branch channel 334, and then control the air intake ratio of the third branch channel 333 and the fourth branch channel 334. Compared with using multiple control valves to control the conduction and blocking of the third branch channel 333 and the fourth branch channel 334, this solution is more convenient to install and more convenient to operate.

[0090] Combined with reference Figures 5 to 8, in one embodiment, a fourth switching valve group 41 is provided at the third air inlet end 401 and the second flow dividing channel 134. The fourth switching valve group 41 includes a seventh switching valve 411 provided in the second flow dividing channel 134 and an eighth switching valve 412 provided at the third air inlet end 401, and the fourth switching valve group 41 controls the air inlet ratio between the third air inlet end 401 and the second flow dividing channel 134. Specifically, the second flow dividing channel 134 is controlled by the seventh switching valve 411, that is, the opening and closing of the second air outlet 132 are controlled. The third air inlet end 401, that is, the first circulating air duct 40, is controlled by the eighth switching valve 412, so as to control the flow direction of the gas, which is convenient for the mutual conversion of the air conditioning system under different modes and / or states. Since both the seventh switching valve 411 and the eighth switching valve 412 are stepless control valves, the inclination angles of the seventh switching valve 411 and the eighth switching valve 412 are rotated to control the opening sizes of the second flow dividing channel 134 (the second air outlet 132) and the third air inlet end 401 (the first circulating air duct 40), and further control the air inlet ratio between the second flow dividing channel 134 (the second air outlet 132) and the third air inlet end 401 (the first circulating air duct 40). Compared with using a single control valve to control the air inlet ratio of the second flow dividing channel 134 (the second air outlet 132) and the third air inlet end 401 (the first circulating air duct 40) at the same time, this solution can more accurately control the air inlet ratio of the second flow dividing channel 134 (the second air outlet 132) and the third air inlet end 401 (the first circulating air duct 40).

[0091] In another embodiment, with reference to Figures 1 to 4 , a fourth control valve 42 is provided at the connection between the third air inlet end 401 and the second flow dividing channel 134. The fourth control valve 42 has an eighth switching position 421 and a ninth switching position 422 that are switched with each other, and the fourth control valve 42 controls the air inlet ratio between the third air inlet end 401 and the second flow dividing channel 134;

[0092] At the eighth switching position 421, the first circulating air duct 40 is conducted, and the second flow dividing channel 134 is blocked; at the ninth switching position 422, the second flow dividing channel 134 is conducted, and the first circulating air duct 40 is blocked.

[0093] Specifically, the fourth control valve 42 controls the mutual conversion between the eighth switching position 421 and the ninth switching position 422, thereby controlling the conduction and blockage between the first circulation air duct 40 and the second diversion duct 134, and thus controlling the gas flow direction. Since the fourth control valve 42 is a stepless control valve, that is, the fourth control valve 42 can rotate to any position between the eighth switching position 421 and the ninth switching position 422, the eighth switching position 421 and the ninth switching position 422 in this solution are the positions where the fourth control valve 42 is in the extreme state. Therefore, the fourth control valve 42 can also control the air intake ratio between the first circulation air duct 40 (the third air inlet end 401) and the second diversion duct 134 (the second air outlet 132). Among them, the fourth control valve 42 can control the opening sizes of the first circulation air duct 40 (the third air inlet end 401) and the second diversion duct 134 (the second air outlet 132) through its deflection angle relative to the first circulation air duct 40 and the second diversion duct 134, and further control the air intake ratio between the first circulation air duct 40 (the third air inlet end 401) and the second diversion duct 134 (the second air outlet 132). Compared with using multiple control valves to control the conduction and blockage between the first circulation air duct 40 (the third air inlet end 401) and the second diversion duct 134 (the second air outlet 132), this solution is more convenient for installation and operation.

[0094] With reference to Figures 5 to 8 , in an embodiment, a fifth switching valve group 51 is provided at the fourth air inlet end 501 and the fourth diversion duct 334. The fifth switching valve group 51 includes a ninth switching valve 511 provided on the fourth diversion duct 334 and a tenth switching valve 512 provided on the fourth air inlet end 501, and the fifth switching valve group 51 controls the air intake ratio between the fourth air inlet end 501 and the fourth diversion duct 334. Specifically, the fourth diversion duct 334 is controlled by the ninth switching valve 511, that is, the opening and closing of the fourth air outlet 332 are controlled, and the third air inlet end 401, that is, the second circulation air duct 50, is controlled by the tenth switching valve 512, so as to control the gas flow direction, which is convenient for the mutual conversion of the air-conditioning system in different modes and / or states. Since both the ninth switching valve 511 and the tenth switching valve 512 are stepless control valves, the inclination angles of the ninth switching valve 511 and the tenth switching valve 512 are rotated to control the opening sizes of the fourth diversion duct 334 (the fourth air outlet 332) and the fourth air inlet end 501 (the second circulation air duct 50), and further control the air intake ratio between the fourth diversion duct 334 (the fourth air outlet 332) and the fourth air inlet end 501 (the second circulation air duct 50). Compared with using one control valve to control the air intake ratio between the fourth diversion duct 334 (the fourth air outlet 332) and the fourth air inlet end 501 (the second circulation air duct 50) at the same time, this solution can more accurately control the air intake ratio between the fourth diversion duct 334 (the fourth air outlet 332) and the fourth air inlet end 501 (the second circulation air duct 50).

[0095] In another embodiment, in conjunction with reference Figures 1 to 4 A fifth control valve 52 is provided at the connection between the fourth air inlet end 501 and the fourth branch channel 334 , and the fifth control valve 52 has a tenth switching position 521 and an eleventh switching position 522 that switch with each other, and the fifth control valve 52 controls the air intake ratio of the fourth air inlet end 501 and the fourth branch channel 334 .

[0096] In the tenth switching position 521 , the second circulation air duct 50 is connected, and the fourth branch flow channel 334 is blocked; in the eleventh switching position 522 , the fourth branch flow channel 334 is connected, and the second circulation air duct 50 is blocked.

[0097] Specifically, the fifth control valve 52 controls the conduction and blocking of the second circulation air duct 50 and the fourth branch channel 334 by controlling the mutual conversion between the tenth switching position 521 and the eleventh switching position 522, thereby controlling the flow direction of the gas. And because the fifth control valve 52 is a stepless control valve, that is, the fifth control valve 52 can rotate at any position between the tenth switching position 521 and the eleventh switching position 522, the tenth switching position 521 and the eleventh switching position 522 in this scheme are both the positions of the fifth control valve 52 in the extreme state. Therefore, the fifth control valve 52 can also control the air intake ratio of the second circulation air duct 50 (the fourth air inlet end 501) and the fourth branch channel 334 (the fourth air outlet 332). Among them, the fifth control valve 52 can control the opening size of the second circulation air duct 50 (fourth air inlet end 501) and the fourth branch channel 334 (fourth air outlet 332) through its deflection angle relative to the second circulation air duct 50 and the fourth branch channel 334, and then control the air intake ratio of the second circulation air duct 50 (fourth air inlet end 501) and the fourth branch channel 334 (fourth air outlet 332). Compared with using multiple control valves to control the conduction and blocking of the second circulation air duct 50 (fourth air inlet end 501) and the fourth branch channel 334 (fourth air outlet 332), this solution is more convenient to install and more convenient to operate.

[0098] In order to further reduce the power loss of the air conditioning system, in one embodiment, the first heat exchange air duct 10 and the second heat exchange air duct 30 are arranged adjacent to or at intervals, a first wind wheel 16 is arranged in the first heat exchange air duct 10, and a second wind wheel 36 is arranged in the second heat exchange air duct 30, and the air conditioning system further includes at least one driving motor, which drives the first wind wheel 16 and the second wind wheel 36 to work. Specifically, the air conditioning system further includes at least one driving motor, that is, one driving motor or two driving motors can be arranged in the air conditioning system.

[0099] In one embodiment, a driving motor is provided in the air-conditioning system. Since the first heat exchange air duct 10 and the second heat exchange air duct 30 are arranged adjacent to or spaced apart from each other, the distance between the first heat exchange air duct 10 and the second heat exchange air duct 30 is relatively close, and the gas flow directions in the first heat exchange air duct 10 and the second heat exchange air duct 30 are the same. To improve the gas flow in the first heat exchange air duct 10 and the second heat exchange air duct 30, a first air wheel 16 is provided in the first heat exchange air duct 10, a second air wheel 36 is provided in the second heat exchange air duct 30, and the same driving motor is used to drive the first air wheel 16 and the second air wheel 36 to work simultaneously. Thereby, the consumption of one driving motor is saved, the installation process is reduced, and further the overall power loss of the air-conditioning system is reduced.

[0100] In another embodiment, two driving motors are provided in the air-conditioning system. Temporarily assume that these two driving motors are a first driving motor and a second driving motor respectively. The first driving motor drives the first air wheel 16 to rotate, and the second driving motor drives the second air wheel 36 to rotate. That is, the two driving motors respectively drive the first air wheel 16 and the second air wheel 36 to rotate, so that the first air wheel 16 and the second air wheel 36 work independently.
