AIR-CONDITIONING CIRCUIT CONDENSER WITH AN UNDERCOOLING PART

摘要

A condenser (10) comprises a first heat exchange block (12), for cooling a refrigerant down to its condensation point by means of a coolant, and a second heat exchange block (14), for undercooling the refrigerant by means of a coolant. The second block (14) incorporates an internal heat exchanger (34) for exchanging heat between the condensed and undercooled refrigerant, called the "high-pressure refrigerant", and the same refrigerant once expanded, called the "low-pressure refrigerant". Application to motor vehicles.
