Problems solved by technology

[0003] In addition, since the electric compressor generates a relatively loud driving sound when it rotates at high speed, if the sound level in the vehicle cabin becomes low and quiet, the driving sound will be harsh to the passengers.

Abstract

Provided is a vehicular air-conditioning device capable of achieving comfortable and efficient in-cabin air-conditioning by appropriately controlling the upper-limit rotation speed of an electric compressor. The air-conditioning device is provided with: a refrigerant circuit R having an air flow path 3, an electric compressor 2, and a radiator 4 for directly or indirectly exchanging heat between arefrigerant and air supplied via the air flow path into a vehicle cabin; an in-cabin blower 27 for circulating air in the air flow path; and a control device. The control device performs air-conditioning of the vehicle cabin by controlling the compressor and the in-cabin blower. The control device changes, on the basis of the air volume of the in-cabin blower, the upper-limit rotation speed to beused when controlling the compressor such that the upper-limit rotation speed is reduced with any decrease in the air volume.

Description

technical field [0001] The present invention relates to a heat pump type air conditioner for air conditioning a vehicle interior, and more particularly to a vehicle air conditioner using an electric compressor. Background technique [0002] Due to the emergence of environmental problems in recent years, hybrid vehicles and electric vehicles have become popular. In addition, as an air conditioner that can be applied to the above-mentioned vehicles, an air conditioner is being developed, which consists of an electric compressor (electric compressor), a radiator (indoor condenser), a heat absorber (indoor evaporator), and an outdoor air conditioner. A heat exchanger constitutes a refrigerant circuit, and switches and executes various operation modes such as a heating mode, a dehumidification mode, and a cooling mode, wherein the above-mentioned electric compressor compresses and discharges the refrigerant, and the above-mentioned radiator is installed inside the vehicle interio...
