[0024] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0025] Reference below Figure 1 An air conditioning system 100 according to an embodiment of the present invention is described, and a vehicle including the air conditioning system 100 is also provided.

[0026] The air conditioning system 100 includes: a refrigerant circuit 10 and a condensed water circuit 20. The refrigerant circuit 10 includes: a compressor 11, a condenser 12 and an evaporator 13, and the compressor 11, the condenser 12 and the evaporator 13 are connected in series. Refrigerant flows in the refrigerant circuit 10, and the refrigerant flows between the compressor 11, the condenser 12 and the evaporator 13. The refrigerant flowing out of the compressor 11 flows to the condenser 12, and after the condenser 12 releases a large amount of heat, it flows from the condenser 12 to the evaporator 13, absorbs heat at the evaporator 13, and finally returns to the compressor 11.

[0027] The refrigerant circuit 10 further includes: a throttling element (not shown in the figure), which is arranged between the condenser 12 and the evaporator 13, and the throttling element can reduce the temperature and pressure of the refrigerant.

[0028] Compression process: The compressor 11 rotates under the drive of the engine, compresses the low-temperature, low-pressure refrigerant vapor into a high-temperature, high-pressure gas, and then sends the gas to the condenser 12.

[0029] Condensation process: High-temperature and high-pressure refrigerant gas enters the condenser 12. In the condenser 12, due to the decrease in pressure and temperature, the refrigerant gas is condensed into liquid and releases a large amount of heat.

[0030] Expansion process: After the condensed liquid comes out of the condenser 12 and passes through the liquid storage drying filter to filter out the water, the liquid refrigerant passes through a throttling element, such as an expansion valve. The expansion valve will reduce the pressure of the liquid refrigerant and instantly expand the volume, turning it into a low-temperature, low-pressure mist mixture, and finally enters the evaporator 13.

[0031] Evaporation process: In the evaporator 13, the low-temperature, low-pressure refrigerant absorbs a large amount of heat from the surrounding air, thereby changing from liquid to gas, and then being sucked into the compressor 11, and this cycle repeats itself.

[0032] The condenser 12 may include a fan. When the refrigerant releases a large amount of heat in the condenser 12, the fan runs at a high speed to dissipate the heat.

[0033] like Figure 1 As shown, the condenser 12 may include a heat exchange tube 121, one end of the heat exchange tube 121 is connected to the compressor 11 and the other end is connected to the evaporator 13. Specifically, after the refrigerant flows from the compressor 11 to the condenser 12, it enters the heat exchange tube 121, releases a large amount of heat to the air at the heat exchange tube 121, and the fan runs to dissipate heat from the condenser 12.

[0034] The condensed water circuit 20 may include: a water tank 21, a connecting pipe 22 and an electronic water pump 23. The water tank 21 is arranged below the evaporator 13 and is used to collect the condensed water generated by the evaporator 13. The water tank 21 includes: a water outlet and a water return port. The condensed water can flow out of the water tank 21 from the water outlet and return to the water tank 21 from the water return port. When the air conditioning system 100 is in cooling and dehumidification conditions, the water tank 21 can store condensed water. The refrigerant is discharged from the compressor 11 and flows to the condenser 12, and releases heat at the condenser 12; the refrigerant then flows to the evaporator 13, absorbs the heat of the air at the evaporator 13, and the moisture in the air condenses to form condensed water, which drips into the water tank 21 under the action of gravity.

[0035] The condensed water circuit 20 may include: a connecting pipe 22, which is disposed in the condenser 12 and is disposed opposite to the heat exchange tube 121. Condensed water may flow from the water storage tank 21 to the connecting pipe 22, which is disposed in the condenser 12, and is disposed opposite to the heat exchange tube 121, so that the condensed water in the connecting pipe 22 is in full contact with the refrigerant in the heat exchange tube 121, thereby improving the condensation efficiency of the condenser 12. When the refrigerant dissipates heat into the air, the air flowing through the connecting pipe 22 can reduce the temperature, that is, the condensed water in the connecting pipe 22 can cool the condenser 12, reducing the time and wind force of the fan cooling the condenser 12, thereby reducing the use of energy on the entire vehicle and improving the energy utilization rate.

[0036] The condensed water circuit 20 may include: an electronic water pump 23, a water tank 21, a connecting pipe 22 and the electronic water pump 23 are connected in series. Specifically, when the air conditioning system 100 is in cooling and dehumidification conditions, driven by the electronic water pump 23, condensed water can flow from the water tank 21 to the connecting pipe 22, so that the condenser 12 can be cooled by the condensed water in the connecting pipe 22, thereby improving the condensation efficiency of the condenser 12; and after the condensed water cools the condenser 12 in the connecting pipe 22, it can return to the water tank 21, so that the condensed water can circulate between the water tank 21 and the connecting pipe 22.

[0037] Thus, the electronic water pump 23 drives the condensed water to flow from the water tank 21 to the connecting pipe 22. The condensed water in the connecting pipe 22 cools down the condenser 12, reducing the time and wind force of the fan cooling down the condenser 12. The condensed water is recycled to improve the condensation efficiency of the condenser 12, thereby saving energy and increasing efficiency for the vehicle.

[0038] like Figure 1 As shown, the condensed water circuit 20 may include: a flow control valve 24, one end of the flow control valve 24 is connected to the water outlet of the water storage tank 21 and the other end is connected to the water inlet of the connecting pipe 22. Specifically, the flow control valve 24 is connected to the water outlet of the water storage tank 21 and the water inlet of the connecting pipe 22. The flow control valve 24 can adjust the flow rate of the condensed water flowing out of the water outlet to adjust the flow rate of the condensed water in the connecting pipe 22, and adjust the cooling effect of the connecting pipe 22 on the condenser 12.

[0039] Further, the condensed water circuit 20 may include: a control valve 25, one end of the control valve 25 is connected to the water outlet of the connecting pipe 22, another end of the control valve 25 is connected to the water return port of the water storage tank 21, and another end of the control valve 25 is connected to the outside. Specifically, the control valve 25 includes: a first valve port, a second valve port and a third valve port, the first valve port is connected to the water outlet of the connecting pipe 22, the second valve port is connected to the water return port, and the third valve port is connected to the outside. When the first valve port and the second valve port are connected, when there is not much condensed water in the connecting pipe 22, all the condensed water in the connecting pipe 22 returns to the water storage tank 21 from the water return port.

[0040] When the first valve port, the second valve port and the third valve port are all connected, when there is too much condensed water in the connecting pipe 22, part of the condensed water can be discharged from the third valve port, and the other part of the condensed water can return to the water storage tank 21 from the return water port.

[0041] In some embodiments, a water level sensor is provided in the water tank 21, and the water level sensor is provided in the water tank 21 for monitoring the water level of the water tank 21. Specifically, the water level sensor can detect the water level of the condensed water in the water tank 21, make full use of the condensed water, and improve the utilization rate of the condensed water.

[0042] In some embodiments, the condensed water circuit 20 may include: a temperature sensor, which is disposed at the water outlet of the connecting pipe 22 and is used to monitor the temperature of the condensed water flowing out of the connecting pipe 22. Specifically, the temperature sensor is disposed at the water outlet of the connecting pipe 22, and the temperature sensor can detect the temperature of the condensed water flowing out of the connecting pipe 22, so as to determine the flow rate of the condensed water required when the condenser 12 is cooled according to the temperature of the condensed water, thereby controlling the flow control valve 24 to adjust the flow rate of the condensed water flowing out of the water outlet of the water storage tank 21.

[0043] The air conditioning system 100 may include: a control module, a water level sensor, a temperature sensor, a control valve 25 and a flow control valve 24 may be electrically connected to the control module, and the control module controls the flow control valve and the control valve according to the water level sensor and the temperature sensor. Specifically, the control module may control the opening of the flow control valve 24 according to the temperature sensor, and the control module may also control the opening and closing of multiple valve ports of the control valve 25 according to the water level sensor and the temperature sensor, and when there is a lot of condensed water, the excess condensed water is discharged.

[0044] The condensed water circuit 20 may include a filter 26, one end of which is connected to the water storage tank 21 and the other end of which is connected to the connecting pipe 22. Specifically, the filter 26 is disposed between the water outlet of the water storage tank 21 and the connecting pipe 22, and the filter 26 filters the condensed water flowing out of the water outlet of the water storage tank 21 to prevent impurities from flowing to the connecting pipe 22.

[0045] like Figure 1 As shown, the water tank 21 may include a drain port 211, which is connected to the outside and is used to drain the water from the water tank 21. When the water level of the condensed water in the water tank 21 is too high, the condensed water can be drained from the drain port 211 to prevent the water tank 21 from overflowing, causing water leakage in the air conditioning system 100, and affecting the user experience.

[0046] The water storage tank 21 may include a water injection port, which is used to inject water into the water storage tank 21. Specifically, when the water level of the condensed water in the water storage tank 21 is too low, the condensed water circuit 20 cannot operate normally. The user can inject water from the water injection port to ensure the normal operation of the condensed water circuit 20, so as to improve the condensation efficiency of the condenser 12.

[0047] When the temperature of the condensed water flowing out of the condenser 12 is low and the amount of condensed water is small, if the condensed water in the water storage tank 21 is insufficient to meet the requirement of continuous circulation of the condensed water loop 20, an appropriate amount of tap water can be injected from the water inlet to ensure the normal operation of the electronic water pump 23 and prevent the electronic water pump 23 from drying out; if the condensed water can meet the requirement of continuous circulation of the condensed water loop 20, the condensed water will not flow out from the third valve port of the control valve 25 but will enter the circulation through the electronic water pump 23.

[0048] When the temperature of the condensed water flowing out of the condenser 12 is low and the condensed water is large, when the condensed water in the water storage tank 21 exceeds a certain level, it can be discharged through the third valve port of the control valve 25 without entering the circulation.

[0049] When the temperature of the condensed water flowing out of the condenser 12 is high and the condensed water in the water storage tank 21 is less, if the condensed water is not enough to lower the temperature of the condenser 12, an appropriate amount of tap water can be injected from the outside through the water inlet to ensure the normal operation of the water pump, so that the condensed water does not flow out from the third valve port of the control valve 25, but all enters the condensed water circuit 20 for circulation.

[0050] When the temperature of the condensed water flowing out of the condenser 12 is high and the condensed water is large, when the condensed water in the condensed water collection tank exceeds a certain level, it can be discharged through the third valve port of the control valve 25 without entering the circulation. If the condensed water increases to the maximum limit of the water level in the water storage tank 21, it can be discharged through the drain port 211 of the water storage tank 21.

[0051] like Figure 1 As shown, the heat exchange tube 121 includes: a plurality of first bends 122 and a plurality of second bends 123, and the plurality of first bends 122 and the plurality of second bends 123 are sequentially staggered. The heat exchange tube 121 includes: a plurality of first bends 122 and a plurality of second bends 123, and the first bends 122 and the second bends 123 are sequentially staggered, and the bending direction of the first bend 122 is opposite to the bending direction of the second bend 123. The first bend 122 and the second bend 123 can increase the contact area between the airflow and the heat exchange tube 121, thereby improving the condensation efficiency of the condenser 12.

[0052] Further, the connecting pipe 22 may include: a plurality of third bend pipes 221 and a plurality of fourth bend pipes 222, the plurality of third bend pipes 221 and the plurality of fourth bend pipes 222 are connected alternately in sequence, the third bend pipe 221 is arranged opposite to the first bend pipe 122, and the fourth bend pipe 222 is arranged opposite to the second bend pipe 123. Specifically, the condensed water flows from the water storage tank 21 to the connecting pipe 22, and the plurality of third bend pipes 221 and the plurality of fourth bend pipes 222 are arranged alternately in sequence. The third bend pipe 221 is arranged opposite to the first bend pipe 122, and the bending direction of the third bend pipe 221 is opposite to the bending direction of the first bend pipe 122. The third bend pipe 221 is arranged close to the first bend pipe 122, so as to improve the heat dissipation efficiency of the condensed water to the condenser 12. The fourth bend pipe 222 is arranged opposite to the second bend pipe 123, and the bending direction of the fourth bend pipe 222 is consistent with the bending direction of the second bend pipe 123, so that the fourth bend pipe 222 can be arranged close to the second bend pipe 123, further improving the heat dissipation efficiency of the condensed water to the condenser 12, that is, improving the condensation efficiency of the condenser 12.

[0053] The vehicle according to the second embodiment of the utility model includes: an air conditioning system 100. The electronic water pump 23 drives condensed water to flow from the water storage tank 21 to the connecting pipe 22, and the condensed water in the connecting pipe 22 cools the condenser 12, reducing the time and wind force of the fan cooling the condenser 12, recycling the condensed water to improve the condensation efficiency of the condenser 12, and playing the role of energy saving and efficiency improvement for the vehicle.
