Abstract

The invention provides a control method and device for a vehicle air conditioning system. The control method comprises the steps that a trigger signal of a dehumidification key is obtained, and in response to the signal, the current working state of the vehicle air conditioning system is obtained; and when the vehicle air conditioner system is in the non-dehumidification mode at present, a compressor of the vehicle air conditioner is controlled to be started, an inner circulation air door and an outer circulation air door of the vehicle air conditioner system are switched to the inner circulation position, and the opening degree of a cold air door and a warm air door of the vehicle air conditioner system is adjusted to the cold air and warm air mixing ratio of 7: 3. The control device comprises a dehumidification key used for starting or stopping a dehumidification mode of the vehicle air conditioning system in a one-key mode; and a controller which is used for executing the control method. According to the vehicle air conditioning system, dehumidification of air in the vehicle body can be achieved, meanwhile, frequent starting and stopping of the compressor in the dehumidification process are avoided, the service life of the compressor can be prolonged, and the comfort of passengers can be improved.

Description

technical field [0001] The invention relates to the field of vehicle technology, in particular to a control method and device for a vehicle air-conditioning system. Background technique [0002] The vehicle air conditioner is a device for cooling, heating, ventilation and air purification of the air in the vehicle compartment. The vehicle air conditioner can provide a comfortable driving environment for the passengers, reduce the fatigue intensity of the driver, and improve driving safety. With the continuous improvement of people's living standards, people put forward higher requirements for the functionality and comfort of automobile air conditioners. [0003] In the prior art, the dehumidification of the vehicle air conditioner is to make the air in the vehicle pass through the refrigeration system, so that the water vapor in the air is liquefied into condensed water through the refrigeration system, and then discharged outside. [0004] However, in the control mode of t...
