Title:
車両用空気調和装置
Document Type and Number:
Japanese Patent JP7221650
Kind Code:
B2
Abstract:
[Problem] To provide an air conditioning device which is for a vehicle and with which the rotation speed of a compressor can be made to quickly respond to a change in a refrigerant flow path accompanying the opening or closing of a valve device, wherein a stable temperature control can be achieved by means of an evaporator. [Solution] This air conditioning device for a vehicle has a heat absorber 9 that vaporizes the refrigerant and a refrigerant-heat medium heat exchanger 64. A heat pump controller controls the rotation speed of a compressor 2 on the basis of the temperature Te of the heat absorber 9, controls the opening and closing of a solenoid valve 69 on the basis of the temperature Tw of the heat medium cooled by the refrigerant-heat medium heat exchanger 64, and increases the rotation speed of the compressor 2 when the solenoid valve 69 opens from a closed state, and/or reduces the rotation speed of the compressor 2 when the solenoid valve closes from an open state.
