CLIMATE CONTROL SYSTEM FOR CONDITIONING THE AIR OF A PASSENGER COMPARTMENT OF A VEHICLE AND METHOD FOR OPERATING THE CLIMATE CONTROL SYSTEM

摘要

The present invention relates to an air conditioning system 1a, 1b, 1c for regulating air in a cabin of an automobile having refrigerant circulation systems 2a, 2b, 2c. The refrigerant circulation system (2a, 2b, 2c) includes a compressor (3), a first refrigerant-air-heat exchanger (4) for transferring heat between the refrigerant and the surrounding air, a first expansion engine (5), and an inlet for the cabin. It has a second refrigerant-air-heat exchanger (6) for conditioning air, an internal heat exchanger (7) and a first flow path (9) and a second flow path (16). The first flow path 9 extends from a branch point 10 formed at the outlet of the compressor 3 to a connection point 11 formed between the second refrigerant-air-heat exchanger 6 and the internal heat exchanger 7 do. The second flow path 16 is an inlet formed in front of the compressor 3 when viewed in the flow direction of the refrigerant from the connection points 17a and 17b formed between the branch point 10 and the first refrigerant-air-heat exchanger 4 It extends to point 18. The internal heat exchanger (7) is arranged inside the first flow path (9) on one side and the connection point (11) of the first flow path (9) and the second flow path (16) on the other hand. It is arranged between the inlet points 18 of. The invention also relates to a method for operating an air conditioning system.
