Title:
VEHICLE AIR CONDITIONING SYSTEM AND THE USE THEREOF
Document Type and Number:
WIPO Patent Application WO1999055544
Kind Code:
A3
Abstract:
The invention relates to a vehicle air conditioning system having a coolant circuit (12) comprised of at least one condenser (14), one expansion organ (16), one evaporator (18), and one compressor (20). The inventive air conditioning system also has a bypass line (24) which bypasses the condenser (14), and has at least one bypass valve (26, 28) for opening and closing said bypass line (24). In order to produce an improved vehicle air conditioning system which can be more effectively used during the warm-up phase of the drive assembly, the invention provides that a heat exchanger (22) is arranged in the coolant circuit (12). Said heat exchanger can be subjected to the action of the coolant and to the action of a coolant of a drive assembly (40). The inventive air conditioning system can be used during the cold-start phase in order to heat up the engine and the passenger compartment more quickly.
