In this embodiment, the refrigerant circulation loop in the air conditioning system is formed by connecting the compressor 1, the first in-vehicle heat exchanger 2, the first throttling device 3, the out-vehicle heat exchanger 4, the second throttling device 5, and the second in-vehicle heat exchanger 6 in sequence, and it can be understood that the refrigerant in the air conditioning system always flows in one direction without switching the flow direction of the refrigerant, that is, the first in-vehicle heat exchanger 2 functions as a condenser to release heat to the outside to heat the airflow passing through it, and the second in-vehicle heat exchanger 6 functions as an evaporator to absorb heat from the outside to lower the temperature of the airflow passing through it. The heat exchange effect of the first in-vehicle heat exchanger 2 and the second in-vehicle heat exchanger 6 can be realized by adjusting the throttle opening of the first throttle device 3 and the second throttle device 5.

The specific adjusting mode can be determined according to the actual situation, optionally, at least including the following working modes:
referring to fig. 1, cooling mode: at this time, the first throttling device 3 is fully opened, the second throttling device 5 is throttled, and meanwhile, the second vehicle interior heat exchanger 6 is opened by the throttle assembly and the first vehicle interior heat exchanger 2 is shielded, so that the airflow entering the air duct 80 from the air inlet does not pass through the first vehicle interior heat exchanger 2 and is blown out from the air outlet to the passenger compartment after passing through the second vehicle interior heat exchanger 6. It can be understood that the first throttling device 3 is arranged in a fully opened mode, the second throttling device 5 is arranged in a throttling mode, the second in-vehicle heat exchanger 6 can absorb heat of airflow flowing through the second in-vehicle heat exchanger as an evaporator, the second in-vehicle heat exchanger 6 is separately opened through the air door assembly, the first in-vehicle heat exchanger 2 is shielded, the airflow can be only cooled by the second in-vehicle heat exchanger 6, the influence of the first in-vehicle heat exchanger 2 cannot be caused, and therefore the effect of pure cooling is achieved.
Referring to fig. 2, heating mode: at this time, the first throttling device 3 is set in a throttling mode, the second throttling device 5 is set in a full-open mode, and meanwhile the air door assembly opens the first vehicle interior heat exchanger 2 and shields the second vehicle interior heat exchanger 6, so that the air flow entering the air duct 80 from the air inlet does not pass through the second vehicle interior heat exchanger 6, and is blown out to the passenger compartment from the air outlet after passing through the first vehicle interior heat exchanger 2. It can be understood that the first throttling device is arranged in a throttling mode, the second throttling device 5 is arranged in a fully-opened mode, so-called condensers of the first vehicle interior heat exchanger 2 can release heat outwards, the first vehicle interior heat exchanger 2 is opened alone by the air door assembly, the second vehicle interior heat exchanger 6 is shielded, air flow can be heated only by the first vehicle interior heat exchanger 2, the air flow cannot be influenced by the second vehicle interior heat exchanger 6, and therefore the effect of pure heating is achieved.

It can be understood that, when refrigeration dehumidification is needed, the temperature and humidity of the air in the passenger compartment are higher at this moment, the first throttling device 3 is arranged in a fully opened mode, the heat exchanger 4 outside the vehicle can release heat outwards, then the heat exchanger 6 in the second vehicle needs to absorb heat outwards after the throttling effect of the second throttling device 5 is carried out, the air flow in the air duct 80 is refrigerated and dehumidified through the heat exchanger 6 in the second vehicle at this moment, the temperature of the air flow after refrigeration and dehumidification is possibly too low, then the air flow after refrigeration and dehumidification is heated through the heat exchanger 2 in the first vehicle according to actual conditions, and the air flow is blown out after reaching the appropriate temperature actually needed.

It can be understood that, when heating dehumidification is required, the temperature of the air in the passenger compartment is lower and the humidity is higher at the moment, the first throttling device 3 is throttled, so that the heat exchanger 4 outside the vehicle can absorb a part of heat outwards, then the heat exchanger 6 in the second vehicle absorbs a part of heat, at the moment, the air flow in the air duct 80 is cooled and dehumidified through the heat exchanger 6 in the second vehicle, the temperature of the air flow after cooling and dehumidifying is too low, and then the air flow after cooling and dehumidifying is heated through the heat exchanger 2 in the first vehicle according to actual conditions, and then the air flow is blown out after reaching the appropriate temperature actually required. It should be noted that the second throttling device 5 may not be provided in a fully opened manner, and may be specifically determined according to the outward heat absorption degree of the exterior heat exchanger 4, which may not be limited herein.
It can be understood that the present air conditioning system can implement multiple operating modes according to actual conditions, which is not limited to the above several operating modes, and the specific opening and closing conditions of the first throttle device 3 and the second throttle device 5 are also determined according to actual requirements, and the conditions or opening sizes of the first vehicle interior heat exchanger 2 and the second vehicle interior heat exchanger 6 that the damper assembly opens or shields are also determined according to actual requirements, and the specific conditions are not listed here.
In practical application, the movable connection mode of the damper assembly and the air conditioning cabinet 8 can also be determined according to practical situations, such as sliding connection or rotating connection.

Meanwhile, a heat regenerator 14 can be arranged at the outlet end of the heat exchanger 4 outside the vehicle or at the inlet end of the compressor 1 to improve the heat exchange efficiency.
The utility model discloses among the technical scheme air conditioning system, through setting up by compressor 1, heat exchanger 2 in the first car, first throttling arrangement 3, outer heat exchanger 4 of car, the refrigerant circulation circuit that heat exchanger 6 connects gradually and forms in second throttling arrangement 5 and the second car, make the flow path direction of refrigerant unchangeable, heat exchanger 2 is as the condenser in the first car, heat exchanger 6 is as the evaporimeter in the second car, all set up heat exchanger 2 and second car in heat exchanger 6 in the air conditioning box 8 of vehicle simultaneously, and set up mobilizable air door subassembly in air conditioning box 8, this air door subassembly can move for air conditioning box 8, the amount of wind size of air current in the regulating duct 80 through heat exchanger 2 in the first car and/or second car in heat exchanger 6, thereby can adjust the refrigeration heat transfer volume and the heating heat transfer volume that get into air current in the duct 80, and then realize the purpose of adjusting the inside air of passenger cabin.

It is understood that, in the cross section of the air duct 80 where the first in-vehicle heat exchanger 2 is located, the air flow may flow through the first in-vehicle heat exchanger 2 in a heat exchange manner, or may flow through the first air opening a directly. Similarly, on the cross section of the air duct 80 where the second inside heat exchanger 6 is located, the air flow can be heat-exchanged from the second inside heat exchanger 6 and can also directly flow through the second air outlet B. Based on this, when the air flow flows from the air inlet to the air outlet of the air duct 80, there may be at least the following different flow paths: the air inlet, the second vehicle interior heat exchanger 6, the first vehicle interior heat exchanger 2 and the air outlet; the air inlet, the second in-vehicle heat exchanger 6, the first air port A and the air outlet; the air inlet, the second air inlet B, the first vehicle interior heat exchanger 2 and the air outlet; air inlet-second wind gap B-first wind gap A-air outlet.
