In an air conditioning unit for a car, which air conditioning unit has a refrigerant circuit with a primary consumer branch having a compressor, condenser, and an evaporator, which air conditioning unit also has at least one auxiliary consumer branch that is connected parallel to the primary consumer branch and has a cold accumulator and its own evaporator, a stop valve is arranged in front of each evaporator. After operational phases charging the cold accumulator, the stop valve of the primary consumer branch is regularly opened for only a predetermined opening time that depends on particular operating parameters. The substantial operating parameters are the air inlet temperature and the air mass flow at the evaporator of the primary consumer branch. |
