Method for controlling a refrigeration cycle and refrigeration cycle.

摘要

Method for controlling a refrigeration cycle for vehicles, said refrigeration cycle comprising a variable capacity compressor, a condenser for condensing a refrigerant, an expansion valve, an evaporator for evaporating adiabatically expanded refrigerant, a bypass line which bypasses said capacitor, and a switching means line to supply both the refrigerant compressed by the compressor to the condenser in a cooling mode as in the bypass line in a heating mode, characterized in that before operating the refrigeration cycle in the way heating, cooling mode is set temporarily maximum capacity compressor and a drop of pressure between a pressure in said condenser (52) and a lower pressure in said evaporator (54) is generated, and in that said drop pressure at least part of refrigerant stored in said condenser (52) is tran sporta out of said condenser (52).
