Embodiment Construction

[0015] Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a vehicle air conditioner according to an embodiment of the present invention, and FIG. 2 is a block diagram showing a schematic configuration of an air conditioning computer.

[0016] In FIG. 1 , a variable capacity compressor 1 includes an electronically operated control valve (hereinafter referred to as ECV) 2 controlled by an electronic signal supplied from the outside. The variable capacity compressor 1 is driven by an engine 3 as a power source for driving the vehicle. The power source for driving the vehicle may also be a motor. The condenser 4 condenses the high-temperature and high-pressure gas refrigerant compressed by the variable capacity compressor 1 . The refrigerant condensed by the condenser 4 is decompressed by the expansion valve 5 and becomes a low-temperature and low-pressure liquid refrigerant, and e...

Abstract

The present invention relates to an air conditioner for a vehicle, which includes: a variable capacity compressor, which compresses refrigerant through a vehicle driving power source of the vehicle, and controls and releases the capacity of the refrigerant; In a state where the fuel consumption rate of the power source is lowered, a second target temperature that is higher than a preset first target temperature by a predetermined temperature is set, and the discharge refrigerant capacity is controlled based on the second target temperature.

Description

technical field [0001] The present invention relates to an air conditioner for a vehicle, and more specifically, to an air conditioner for a vehicle that achieves both comfort and fuel consumption. Background technique [0002] As we all know, in the air conditioner for vehicles, the compressor driven by the vehicle driving power source such as the engine compresses the gas refrigerant, and the high temperature and high pressure gas refrigerant is condensed by the condenser, and the gas refrigerant is condensed by the expansion unit. After the pressure is reduced, it is made into a low-temperature and low-pressure liquid refrigerant, which is evaporated by the evaporator to cool the air-conditioning air blown out of the car interior. The refrigerant evaporated by the evaporator is returned to the compressor, and the above cycle is repeated. [0003] In recent years, in response to a demand for improved fuel consumption, variable capacity compressors equipped with electronic...
