A thermal system includes a high temperature coolant loop thermally coupled to a heater core configured for thermal exchange with an airflow into a cabin of the vehicle, and an air conditioning (A/C) loop having a compressor, a condenser, a first expansion device for a heat exchanger, a second…
A dehumidification mode control method and apparatus, a device, a medium and a program product, implemented by means of: obtaining a dehumidification load of a heat pump system and an external ambient temperature when it is detected that a passenger compartment has a dehumidification demand…
The invention relates to a method for controlling a refrigeration system (1) of a vehicle. The refrigeration system comprises a circuit (2) containing a refrigerant, a compressor (3), and a first evaporator (4) and a second evaporator (5) which are connected in parallel to the compressor, and a…
To suppress frost formation on an evaporator and to enhance operating efficiency at low costs. At the time of startup of a vehicle refrigeration unit, a dehumidifying operation mode (S104) is started if the discharge temperature of the evaporator is equal to or more than a reference temperature T1…
The method involves computing water load capacity of a cooling element based on air temperature, air humidity, air mass flow before and after the element or estimating the load capacity based on air temperature gradation and under consideration of actual active air cooling capacity of the element…
In a vehicle air conditioner, a refrigerant cycle system is constructed to switch a cooling refrigerant cycle (C) where an interior heat exchanger (18) is used as an evaporator, and a hot gas heater cycle (H) where the interior heat exchanger is used as a radiator. Further, it is determined whether…
