Air conditioner for vehicle, using flammable refrigerant
First Claim
1. An air conditioner for a vehicle having a passenger compartment, said air conditioner cooling air by evaporation latent heat of refrigerant, comprising:
- air conditioning equipments for forming a refrigerating cycle in which said refrigerant flows, at least one of which is positioned away from said passenger compartment and may be damaged by outer force, said one of air conditioning equipments having an inlet port for receiving said refrigerant and an outlet port for discharging said refrigerant;
outer force detecting means for detecting outer force applied to said vehicle; and
a valve device including two valves disposed at said inlet port and said outlet port, respectively, said two valves being closed when outer force detected by said outer force detecting means is equal to a predetermined value or more.

Abstract
In an air conditioner according to the present invention, the first and second electromagnetic valves are disposed at the outlet port and the inlet port of the condenser, which is disposed at a position away from the passenger compartment and may be easily damaged by the outer force when the vehicle collides. The first and second electromagnetic valves are closed when the outer force applied to the vehicle is equal to a predetermined value or more. In this way, an amount of leaking refrigerant is as much as the amount accumulated in the air conditioning devices at most, thus making it possible to reduce the leakage of the refrigerant.
