Problems solved by technology

[0003] At present, the interior of the car is equipped with an automatic air conditioner. After the car engine is started, the automatic air conditioner in the car automatically heats up through the waste heat of the gradually rising water temperature, and then realizes the purpose of automatically adjusting the air conditioning system to change the temperature inside the car, so as to improve the comfort of users. However, when the vehicle is in a cold environment for a long time, the heating period of the engine water temperature in the vehicle is longer, resulting in a slow change in the temperature inside the vehicle

Abstract

The invention provides a heating method and device of an automobile air conditioner. When it is judged that a received automobile signal meets a preset condition after an automobile air conditioner system is started, a heater PTC is controlled to carry out heating, then an automobile is heated when the temperature rise of water in an automobile engine is slow at the initial period, and the temperature rise speed inside the automobile is improved. Later, when it is judged that a collected water temperature signal reaches a certain water temperature value after heating, the heater PTC is controlled to stop carrying out heating. At the time, the automobile air conditioner system still carries out automatic heating by means of waste heat of the water, and the problems that in a low-temperature environment, the temperature rise period of the water temperature in the automobile engine is long, and the temperature inside the automobile changes slowly are solved.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, and more specifically relates to a heating method and device for an automobile air conditioner. Background technique [0002] With the market competition and the continuous improvement of users' material life, more and more users are not only pursuing the power of the car, but also gradually paying attention to the comfort of the car. Among them, the comfort of the car air conditioner is an important evaluation standard. [0003] At present, the interior of the car is equipped with an automatic air conditioner. After the car engine is started, the automatic air conditioner in the car automatically heats up through the waste heat of the gradually rising water temperature, and then realizes the purpose of automatically adjusting the air conditioning system to change the temperature inside the car, so as to improve the comfort of users. However, when the vehicle is in a cold envi...
