Control method of vehicle-mounted air conditioner and vehicle-mounted air conditioner

Abstract

The invention discloses a control method of a vehicle-mounted air conditioner and the vehicle-mounted air conditioner. The method includes the steps that a compartment is divided into a plurality of areas, a temperature sensor, a carbon dioxide sensor and a fan are installed in each area, and an external temperature sensor is installed in the position, away from a heat source, of the exterior of the compartment; after a vehicle is started, the air conditioner is started and the operating mode is determined according to the vehicle exterior environmental temperature detected by the external temperature sensor; the air speed gears of the fans in the corresponding areas are adjusted according to the carbon dioxide concentrations, detected by the carbon dioxide sensors, of all the areas; the set temperature is adjusted according to the current operating mode and the air speed gears of the fans in all the areas; and when the temperature sensor detects that the temperatures of multiple areas reach the set temperature, the air conditioner starts the shutdown mode, and the fans are kept at the current air speed gear. According to the control method of the vehicle-mounted air conditioner and the vehicle-mounted air conditioner, interior temperature and exterior temperature of the compartment are identified through the sensors, and the operating modes of the air conditioner are selected automatically; the number of passengers of different areas is judged based on the carbon dioxide concentrations in the vehicle, the air outlet volume is adjusted according to the areas, the requirements of passengers for cooling and heating are met anytime, and accordingly the comfort is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a method for controlling a vehicle-mounted air conditioner and the vehicle-mounted air conditioner. Background technique [0002] With the continuous development of industry and the acceleration of urbanization, people have higher and higher requirements for air-conditioning technology, and the automatic adjustment ability of air-conditioning is one of the concerns. Buses are a common means of transportation in daily life, and are an important tool for most people to travel in daily life. The comfort of heating and cooling on board is an important demand of passengers. [0003] At present, most buses adopt manual control or semi-automatic control to the control of air-conditioning. [0004] Manual control is to manually start and stop the on-board air conditioner by the bus driver, and the temperature adjustment is by the driver to adjust the high and low gears ...
