Vehicle air conditioning system has cold storage device between cold heat exchanger downstream side, flap upstream aide cooled by cold air after passing through cold heat exchanger

摘要

The system has a housing defining an air passage for air to flow into the passenger compartment, a cold heat exchanger in the passage to cool the air, a hot heat exchanger on the downstream side to heat the air, an air mixing flap that sets a throughput ratio between air passing through the heat exchangers and a cold storage device between the cold heat exchanger and the flap cooled by the cold air after passing through the cold heat exchanger. The system has a housing (10) for defining an air passage for air to flow into the passenger compartment, a cold heat exchanger (9) in the passage to cool the air, a hot heat exchanger (20) on the downstream side of the cold heat exchanger to heat the air, an air mixing flap (19) that sets a throughput ratio between air passing through the heat exchangers and a cold storage device (40) between the downstream side of the cold heat exchanger and the upstream aide of the flap that is cooled by the cold air after passing through the cold heat exchanger.
