Problems solved by technology

Therefore, there is a problem that in summer, when the idling stop state continues for a while, the interior temperature of the vehicle rises due to a drop in cooling performance.
[0006] On the other hand, there is a problem that in the technique disclosed in the above publication, when the vehicle enters an idle stop, the amount of introduction of the inside air is controlled by adjusting the opening degree of the inside and outside air damper according to the temperature of the inside of the vehicle and the evaporator, For example, as the outside air temperature becomes higher in summer or lower in winter, the amount of heat exchange in the evaporator or heater increases, thereby reducing the energy required to introduce cool or warm air into the vehicle interior. time
In other words, the idle stop duration becomes shorter depending on the outside temperature, which is not desirable

Abstract

The present invention relates to an air conditioner for idling stop vehicle. When idling is stopped, the fan stage is set to Lo2 or lower. Furthermore an opening thetad of an inner-outer air brake can be changed according to the temperature Ta of outer air.

Description

Technical field [0001] The present invention relates to an air conditioner for a vehicle, and more particularly, to a device capable of improving the comfort during idling stop. Background technique [0002] Conventionally, in an idling stop vehicle that is not equipped with a device such as an electric compressor, it is configured such that at the time of idling stop, the air-conditioning device also becomes a state of stop operation as the engine is stopped. Therefore, there is a problem that in the summer, when the idling stop state continues for a period of time, the internal temperature of the vehicle rises due to the decrease in cooling performance. In winter, the dehumidification performance decreases, which may cause fogging and blurring of car windows. [0003] In order to solve these problems, a technology has been developed: when the vehicle enters the idling stop mode while the air conditioner is operating in the heating mode, if the internal temperature of the vehicle...
