Refrigeration circuit, A method for air conditioning of a vehicle and vehicle

The invention relates to a refrigeration circuit (2), in particular for a vehicle, with two evaporator branches (10, 12) which are connected in parallel to each other, wherein in the first evaporator branch (10) disposed a first expansion valve (16) and a first evaporator (18) are, for air-conditioning of a first component (20), and in the second evaporator branch (12), a second expansion valve (22) and a second evaporator (24), for air-conditioning of a second component (26). The refrigerant circuit (2) is characterized in that in the second evaporator branch (12) downstream of the second evaporator (24), a pressure control element (28) is arranged for selective pressure control in the second evaporator branch (12). Furthermore, the invention relates to a method for air conditioning of a vehicle and a vehicle.
