Abstract
A refrigerant circuit, which can be used in a vehicle or motor vehicle, includes an air conditioning compressor, a main condenser, at least one connectable condenser, and a switching valve. The switching valve can connect one or more of the switchable condensers to the refrigerant circuit. The circuit may also include a pressure equalizing device with an electric heater that can equalize an internal pressure of the at least one connectable condenser with an internal pressure of the main condenser.
Claims26
A refrigerant circuit configured to be used in a motor vehicle, the refrigerant circuit comprising:
- an air conditioning compressor;
- a main condenser;
- at least one connectable condenser;
- a switching device comprising a switching valve that is configured to connect to the at least one connectable condenser;
- and
- a pressure equalising device comprising an electric heater and/or a capillary configured to equalise an internal pressure of the at least one connectable condenser with an internal pressure of the main condenser.
A method for operating a refrigerant circuit comprising an air conditioning compressor, a main condenser, and a switching valve, the method comprising:
- operating the main condenser in a permanently active manner;
- and
- before and/or during a connection of at least one connectable condenser to the switching valve, equalizing, using a pressure equalising device comprising a pressure equalising capillary and/or capillary bores, an internal pressure of the at least one connectable condenser to an internal pressure of the main condenser.
A motor vehicle, comprising:
- an air conditioning compressor;
- a main condenser;
- at least one connectable condenser;
- a switching device comprising a switching valve that is configured to connect to the at least one connectable condenser;
- and
- a pressure equalising device comprising an electric heater and/or a capillary configured to equalise an internal pressure of the at least one connectable condenser with an internal pressure of the main condenser.
