Abstract
An air-conditioning system for a vehicle includes an electronic control unit which detects a collision of the vehicle and activates an air bag of the vehicle, and a circulation passage for a refrigerant or R152a. The system further includes a discharge device which discharges the refrigerant from the circulation passage in the engine room when the control unit outputs an air-bag activation signal. The discharge device includes an electromagnetic valve adapted to opened to discharge a refrigerant from the circulation passage in the engine room when the control unit outputs the signal.
Claims9
An air-conditioning system for a vehicle, the vehicle having a safety device, the system comprising:
- an electronic control unit for detecting a collision of the vehicle and activating the safety device;
- a circulation passage extended from an engine room of the vehicle by way of an instrument space between the engine room and a vehicle compartment, for circulating a refrigerant;
- and
- a discharge device for discharging the refrigerant from said circulation passage in the engine room when said electronic control unit outputs an activation signal to the safety device,
- wherein said discharge device includes an electromagnetic valve connected to said circulation passage in the engine room and adapted to be opened to discharge the refrigerant from said circulation passage therethrough when said electronic control unit outputs the activation signal to said safety device,
- wherein said discharge device includes a relay adapted to be closed based on the activation signal supplied from said electronic control unit to said safety devices said relay producing a drive signal to said electromagnetic valve to open said electromagnetic valve, and
- wherein said discharge device includes a hose extending between the outside of the vehicle and said electromagnetic valve.
