Description
Technical Field
The present disclosure relates to air conditioning systems, and particularly to an air conditioning system for a vehicle.
Background
Conventionally, a vehicle air conditioning system is provided in a vehicle to provide a comfortable temperature inside the vehicle. In a refrigerant circulation line of a vehicle air conditioning system, after the operation of the refrigerant circulation line is stopped, the refrigerant in the line is in a gas-liquid two-phase state, and the gas-liquid two-phase refrigerant flows toward an expansion valve, thereby generating noise in the expansion valve. Therefore, it is necessary to adjust the design of the vehicle air conditioning system to avoid the above noise problem.
SUMMERY OF THE UTILITY MODEL
The utility model provides an air conditioning system for a vehicle, which can prevent a gas-liquid two-phase refrigerant from flowing to an expansion valve to generate noise at the expansion valve.
The utility model provides an air conditioning system for a vehicle, comprising a compressor; an outdoor heat exchanger connected to the compressor; an expansion valve connected to the outdoor heat exchanger; an evaporator connecting the expansion valve and the compressor, wherein a refrigerant compressed by the compressor flows from the compressor into the outdoor heat exchanger, the refrigerant flows from the outdoor heat exchanger into the evaporator through the expansion valve to absorb heat, and the refrigerant returns from the evaporator to the compressor; a pipe line disposed on an inflow side of the expansion valve; and a heat storage material disposed in the pipeline.
In view of the above, in the vehicle air conditioning system according to the present invention, the heat storage material is provided in the pipe on the inflow side of the expansion valve. After the operation of the vehicle air conditioning system is stopped, the gas-liquid two-phase refrigerant in the pipe is heated and gasified by the heat storage material at the pipe on the inflow side of the expansion valve, so that the gas-liquid two-phase refrigerant is prevented from flowing into the expansion valve. Accordingly, the air conditioning system for the vehicle can prevent the gas-liquid two-phase refrigerant from flowing to the expansion valve to generate noise on the expansion valve.
In order to make the aforementioned and other features and advantages of the utility model more comprehensible, embodiments accompanied with figures are described in detail below.

Detailed Description
Fig. 1 is a schematic view of an air conditioning system for a vehicle according to an embodiment of the present invention. Referring to fig. 1, the vehicle air conditioning system 100 of the present embodiment includes a compressor 110, an outdoor heat exchanger 120, an expansion valve 130, and an evaporator 140. The compressor 110 and the outdoor heat exchanger 120 are connected through a pipe P1. The outdoor heat exchanger 120 and the expansion valve 130 are connected through a pipe line P2. Expansion valve 130 is connected to evaporator 140 via line P3. The evaporator 140 is connected to the compressor 110 via a line P4. Thus, the compressor 110, the outdoor heat exchanger 120, the expansion valve 130, and the evaporator 140 constitute a refrigerant circuit.
The compressor 110 compresses a refrigerant, and the refrigerant compressed by the compressor 110 flows from the compressor 110 into the outdoor heat exchanger 120 through a line P1. The refrigerant from the outdoor heat exchanger 120 flows through the line P2 into the expansion valve 130. Refrigerant from expansion valve 130 flows through line P3 to evaporator 140. Refrigerant from the evaporator 150 returns to the compressor 110 through line P4.
Fig. 2 shows a schematic view of the vehicle air conditioning system of fig. 1 at an expansion valve. After the operation of the vehicle air conditioning system 100 is stopped, a gas-liquid two-phase refrigerant exists in the pipe line P2 on the inflow side of the expansion valve 130. In order to prevent the gas-liquid two-phase refrigerant from flowing to the expansion valve 130 and causing noise in the expansion valve 130, the vehicle air conditioning system 100 of the present embodiment further includes a heat storage material 150, as shown in fig. 2, and the heat storage material 150 is disposed in the pipe line P2 on the inflow side of the expansion valve 130. The gas-liquid two-phase refrigerant R in the line P2 is heated and gasified by the heat storage material 150 in the line P2, so that the gas-liquid two-phase refrigerant R is prevented from flowing into the expansion valve 130. For example, the liquid-phase refrigerant R of the gas-liquid two-phase refrigerant R is vaporized into the gas-phase refrigerant R by heat supplied from the heat storage material 150, so that all the refrigerant R flows into the expansion valve 130 in a gas-phase state. Accordingly, the air conditioning system 100 for a vehicle according to the present embodiment can prevent the gas-liquid two-phase refrigerant from flowing toward the expansion valve 130 and causing noise in the expansion valve 130.
The heat storage material 150 of the present embodiment may be a heat storage structure made of any suitable heat storage material that is capable of storing heat in the environment and supplying heat to the refrigerant R flowing through the line P2. The heat storage material 150 may be disposed on an outer surface of the pipe line P2 adjacent to one end of the expansion valve 130, as shown in fig. 2. In other embodiments, the heat storage material 150 may be disposed at other suitable positions of the pipe P2, and the utility model is not limited thereto.
As described above, in the vehicle air conditioning system according to the present invention, the heat storage material is provided in the pipe on the inflow side of the expansion valve. After the operation of the vehicle air conditioning system is stopped, the gas-liquid two-phase refrigerant in the pipe is vaporized by the heat storage material at the pipe on the inflow side of the expansion valve to prevent the gas-liquid two-phase refrigerant from flowing into the expansion valve. Therefore, the vehicle air conditioning system can prevent the gas-liquid two-phase refrigerant from flowing to the expansion valve to generate noise on the expansion valve.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
