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 air conditioning systems 1a and 1b for regulating air in a cabin of a vehicle including refrigerant circulation systems 2a and 2b and air conditioning equipment 20. The refrigerant circulation system (2a, 2b) controls the compressor (4), the first refrigerant-air-heat exchanger (5) for transferring heat between the refrigerant and the surrounding air, the expansion engine (7), and the inlet air for the cabin. A second refrigerant-air-heat exchanger (8) for. The refrigerant circulation systems 2a, 2b also have a flow path 10 extending from the branch point 12 to the inlet point 13 and formed with a heat exchanger 11. At this time, the branch point 12 is formed at the outlet of the compressor 4, and the inlet point 13 is disposed between the first refrigerant-air-heat exchanger 5 and the expansion engine 7. The air conditioning equipment 20 includes a housing for guiding and distributing inflow air for the cabin, and the housing includes a first flow channel 21 and a second flow channel 21 in which a second refrigerant-air-heat exchanger 8 is disposed. It is equipped with a second flow channel 22 formed as a bypass bypassing the refrigerant-air-heat exchanger 8. The air conditioning equipment 20 has also been formed with a flow guide device 29 for closing and opening the first flow channel 21. The invention also relates to a method for operating an air conditioning system.
