Problems solved by technology

[0008] The above three evaporators have their own advantages and disadvantages, but when dealing with condensation, they generally adopt the method of setting up a water tank. In the case of a large amount of condensed water, the drainage capacity is not enough, and the water drops downward When flowing, it is easy to block the gap between the heat sinks, reduce the contact area between the air intake air and the heat sink, that is, the heat transfer area, and affect the cooling effect of the evaporator

Embodiment 1

[0033] like Figure 5 As shown in the figure, a method for removing mold from an air conditioner evaporator for a vehicle includes the reverse output of the refrigerant vapor compressed by the compressor 1 in the refrigeration operation of the air conditioning system to the evaporator 4, and the heat of the refrigerant vapor is directly conducted to the evaporator 4. It is heat sterilized.

[0034] The method of reversely outputting the refrigerant vapor compressed by the compressor 1 to the evaporator 4 is as follows: adjusting the four-way reversing valve 5 in the air conditioning system, so that the refrigerant vapor compressed by the compressor 1 is reversely transported to the evaporator 4. In the refrigerant delivery channel in the device 4. After the refrigerant vapor enters the refrigerant conveying channel in the evaporator 4 and exchanges heat with the evaporator 4, the refrigerant passes through the throttle valve 3 and the external heat exchanger 2 in turn, and fi...

Embodiment 2

[0040] like Image 6 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the method of reversely outputting the refrigerant vapor compressed by the compressor 1 to the evaporator 4 is: adding a combined solenoid valve 6 in the air conditioning system, The combined solenoid valve 6 is connected to the input and output pipelines of the external heat exchanger 2, the compressor 1 and the evaporator 4, and the refrigerant vapor compressed by the compressor 1 is regulated by the combined solenoid valve 6 to be reversely transported to the evaporator. 4 in the refrigerant delivery channel.

[0041] It should be noted that the function of the combined solenoid valve 6 is the same as that of the four-way reversing valve 5. Specifically, the connecting pipeline between the compressor 1 and the external heat exchanger 2, the compressor 1 and the evaporator can be controlled by the four solenoid valves respectively. The connecting pipeline between the...

Embodiment 3

[0043] like Figure 5-7 As shown, a mold removal system for realizing the vehicle air conditioner evaporator of the above-mentioned embodiment 1-2 includes an air conditioner system composed of a compressor 1, an external heat exchanger 2, a throttle valve 3 and an evaporator 4, and a The four-way reversing valve 5 or the combined solenoid valve 6 in the air conditioning system, the compressor 1, the external heat exchanger 2, the throttle valve 3 and the evaporator 4 are sequentially connected through the refrigerant conveying pipeline, and the evaporator 4 is connected by the return flow The pipeline is connected to the compressor 1 , and the four-way reversing valve 5 or the combined solenoid valve 6 is arranged on the refrigerant conveying pipeline connected to the compressor 1 , the external heat exchanger 2 and the evaporator 4 .

Abstract

The invention relates to a mold removal system and method for a vehicle air conditioner evaporator, comprising a heat conduction structure installed on the evaporator, an air intake pipe and an air outlet pipe connected to the input end and output end of the heat conduction structure, and the air intake pipe passes through an air intake solenoid valve Connected with the compressor, the refrigerant vapor compressed by the compressor is sent to the heat conduction structure, and the heat conduction structure conducts the heat energy to the evaporator, and the evaporator is heated to remove condensation and sterilize. The invention breaks the conventional evaporator which only has the function of evaporative refrigeration, and redefines the evaporator in the car, so that the evaporator not only has the function of evaporative refrigeration but also has the function of high-temperature sterilization, and keeps the surface of the evaporator dry to create an unfavorable survival for mold. surroundings.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning systems, and in particular relates to a mold removal system and method for a vehicle air-conditioning evaporator. Background technique [0002] The compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous state, and sends it to the external heat exchanger for cooling. After cooling, it becomes a medium-temperature and high-pressure liquid refrigerant and enters the drying bottle for filtration and dehumidification. The throttle valve is depressurized and becomes a low-temperature and low-pressure gas-liquid mixture, which is vaporized through the evaporator to absorb the heat in the air and becomes a gaseous state, and then returns to the compressor to continue to compress and continue to circulate for refrigeration. When heating, there is a four-way reversing valve so that the flow direction of the refrigerant in the external heat exchanger and the ...
