Problems solved by technology
[0002] At present, there is a problem that the performance of the external heat exchanger of the front-end cooling module in some working conditions is insufficient in the current automotive air-conditioning technology, resulting in a decrease in the performance of the air-conditioning system. Insufficient performance. In extreme cases, such as heating conditions, the front-end heat exchanger is frosted and the air conditioning system cannot operate, and the heat pump system cannot work at all.
In the cooling condition, when passengers set the air-conditioning box to the external circulation air intake, the cooling performance is often poor, and there is a problem of high condensation pressure in the air-conditioning system

The invention discloses a vehicle, a vehicle air-conditioning system and a control method, and the vehicle air-conditioning system is additionally provided with a communicating pipeline which is used for guiding gas of a second cabin to an upstream gas inlet area of a temperature adjusting module of a refrigerant circulating system. In this way, gas flowing out of the second cabin can further flow through a temperature adjusting module of the refrigerant circulating system to exchange heat with refrigerant in the temperature adjusting module and enter the first cabin, obviously, the air conditioning system is in a heating mode, the gas in the second cabin is heated by the air conditioning box, and the temperature of the gas is inevitably higher than the external environment temperature; thus, the use requirement of the first cabin can be met only by absorbing a small amount of heat through the temperature adjusting module, and then energy-saving and efficient effects can be achieved by utilizing part of heat heated by the air conditioning box. Similarly, when the air-conditioning system is in a refrigeration mode, the temperature of gas flowing out of the second cabin is inevitably lower than that of outside gas, the cooling capacity of the air-conditioning box can be further utilized, and the overall energy-saving and efficient effects of the air-conditioning system are achieved.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle, a vehicle air conditioning system and a control method. Background technique [0002] At present, there is a problem in automotive air conditioning technology that the performance of the external heat exchanger of the front-end cooling module is insufficient in some working conditions, resulting in a decrease in the performance of the air conditioner. Insufficient performance. In extreme cases, such as the frosting of the front-end heat exchanger under heating conditions, the air-conditioning system cannot operate, and the heat pump system cannot work at all. In the cooling condition, when passengers set the air-conditioning box to the external circulation air intake, the cooling performance is often poor, and there is a problem of excessively high condensing pressure of the air-conditioning system. [0003] How to overcome the above-mentioned defects in the prior ar...
