Embodiment Construction

[0055] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0056] Please refer to figure 1 , figure 1 It is a structural schematic diagram of the first specific embodiment of the automobile air-conditioning system.

[0057] In this embodiment, the automobile air-conditioning system includes a compressor 1, an outdoor heat exchanger 2, an indoor heat exchanger 3, an indoor condenser 4, a first expansion device 5 and a second expansion device 6; It can play the role of throttling and reducing pressure. Generally, there are throttling tubes, ordinary thermal expansion valves or electronic expansion valves, etc. The expansion valve is used as an example in the illustration.

[0058] Wherein, the outdoor heat exchanger 2 includes N outdoor heat exchange parts, and the outdoor heat exchange par...

Abstract

The invention discloses an automobile air-conditioning system. The air-conditioning system includes a compressor, an outdoor heat exchanger, an indoor heat exchanger, an indoor condenser and a first expansion device; the outlet of the compressor communicates with the inlet of the indoor condenser; the outlet of the indoor condenser can communicate with the outdoor heat exchanger; the first expansion device communicates with the first connection port of the indoor heat exchanger; the air-conditioning system includes a deicing mode, a heating mode and a refrigeration mode; the outdoor heat exchanger includes N outdoor heat exchanging parts, and the outdoor heat exchanging parts do not communicate with each other, wherein N >= 2; and in the deicing mode, the indoor condenser is in a bypass state, the outlet of the compressor communicates with N-1 outdoor heat exchanging parts at the most, and the N-1 outdoor heat exchanging parts communicate with the indoor heat exchanger through the first expansion device. The air-conditioning system can rapidly and effectively deice the outdoor heat exchanger.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an automobile air conditioning system. Background technique [0002] The automotive air-conditioning system includes a compressor, an outdoor heat exchanger, a gas-liquid separator, an indoor evaporator, and an indoor condenser. All components are connected through corresponding pipelines to form a complete heat pump air-conditioning system. [0003] When the automotive air-conditioning system is heating in a low-temperature environment, the outdoor heat exchanger acts as an evaporator to absorb external heat. Due to the low ambient temperature and the presence of water vapor in the air, the outdoor heat exchanger has the problem of freezing. Once the outdoor heat exchanger Freezing will greatly reduce the heat exchange capacity of the outdoor heat exchanger, so it is necessary to de-ice the outdoor heat exchanger. [0004] In order to de-ice, the current practice is to...
