Japanese Patent JP7467988
Kind Code:
B2
Abstract:
To control fluid sound when an operation mode is switched.SOLUTION: A vehicle air-conditioning device comprises: opening-and-closing sections 14a and 14b which open and close an air-conditioning coolant passage from a branch section to an air-conditioning evaporation section and a cooling coolant passage from the branch section to an air-conditioning decompression section; and a control section 50 which controls operation of the opening-and-closing sections in a manner that opens the air-conditioning coolant passage when a request is made for cooling air-conditioning air, closes the air-conditioning coolant passage when no request is made for cooling the air-conditioning air, opens the cooling coolant passage when a request is made for cooling a cooling object, and closes the cooling coolant passage when no request is made for cooling the cooling object. The control section also controls the opening-and-closing sections in a manner that reduces coolant discharge capacity of a compressor and keeps the air-conditioning coolant passage closed until a predetermined condition is met when a state where no request is made for cooling the air-conditioning air and a request is made for cooling the cooling object is transferred to a state where no request is made for cooling the cooling object.SELECTED DRAWING: Figure 29
