Coolant management for an after-heating operation of a refrigeration system for a vehicle, refrigeration system and a vehicle equipped with such a refrigeration system

摘要

The invention concerns an after-heating process (500) to operate a refrigeration system (10) with heat pump function for a vehicle, the refrigeration system (10) comprising:a refrigerant condenser (12) which is connected or connected to a primary (14) and a secondary (16) strand;an external heat transmitter (18) located in the primary stream (14);a evaporator (22) located in the primary stream (14);a heating register (26) arranged in the secondary circuit (16);at least one after-heating expansion valve (AE4) located between the heating register (26) and the external heat transmitter (18) in the secondary circuit (16).The after-heating process includes the following steps:Determine (S503) a heat differential value (Wdiff) by comparing a heat output real value (knowledge) in the heat register (26) with a heat output default value (wool),Adjust (S507) from at least one operating setting of the cooling system (10) to increase the load absorption in the cooling system (10) if the heat differential value (Wdiff) is greater than 0 and less than a heat differential threshold (Wds).In addition, a cooling system to perform the after-heating process and a motor vehicle with such a cooling system are described.
