Abstract:
A method for operating a climate control system for a vehicle, in the case of which a compressor (38), in a cooling mode, circulates a coolant through a gas condensing apparatus (42) and an expansion device (50) to a passenger-compartment heat exchanger (44) and, in a heating mode, circulates the coolant in the reverse direction of flow first through the passenger-compartment heat exchanger (44), the expansion device (50) and then through the gas condensing apparatus (42), in parallel with which a bypass line (56) comprising a switching valve (58) is provided,wherein, in the heating mode, the switching valve (58) in the bypass line (56) is opened and the flow of coolant through the gas condensing apparatus (42) is stopped as soon as an ice layer that exceeds a limit thickness has formed on the air side of the gas condensing apparatus (42).
