Abstract
Official abstract text for this publication.
An air conditioner for a vehicle is provided with: a compressor that compresses a heat exchange medium; an external heat exchanger that receives the heat exchange medium and that exchanges heat with the outside of a vehicle compartment; and an evaporator that receives the heat exchange medium and exchanges heat with the inside of a vehicle compartment, and the air conditioner for a vehicle is able to perform: a defrosting cooling operation in which the heat exchange medium that has been compressed by the compressor is made to flow into the evaporator and absorb heat, and to then flow into the external heat exchanger and release heat; and a hot gas operation in which the heat exchange medium that has been compressed by the compressor is made to flow into the external heat exchanger and release heat without being made to absorb heat in the evaporator, and, by switching between performing the defrosting cooling operation and performing the hot gas operation, the air conditioner for a vehicle performs a defrosting operation in which the external heat exchanger is defrosted.
First claim
Opening claim text (preview).
What is claimed is: 1. An air conditioner for a vehicle, comprising: a compressor that compresses a heat exchange medium; an external heat exchanger that receives the heat exchange medium and that exchanges heat with the outside of a vehicle compartment; and an internal heat exchanger that receives the heat exchange medium and exchanges heat with the inside of a vehicle compartment; a controller that controls the air conditioner for a vehicle; and a damper that adjusts an air volume that is introduced into an internal condenser, wherein the controller is configured to control the air conditioner to perform: a defrosting cooling operation in which the damper is opened and the heat exchange medium that has been compressed by the compressor is made to flow into the internal condenser, then to flow into the external heat exchanger to release heat, and then to flow into the internal heat exchanger to absorb heat; and a hot gas operation in which the heat exchange medium that has been compressed by the compressor is made to flow into the internal condenser and then to flow into the external heat exchanger to release heat, and wherein the air conditioner for a vehicle performs a defrosting operation in which the defrosting cooling operation and the hot gas operation are alternately performed to thereby defrost the external heat exchanger.
