摘要： The invention relates to a compact vehicle HVAC system including an evaporator unit, a condenser unit, and a component unit, as well as a refrigerant circuit. The evaporator unit and the condenser unit each are provided with air-passed heat exchangers and a fan in a casing. Further circuit components are displaced within the component unit. The casings of the evaporator unit, the condenser unit, and the component unit advantageously establish a connected compact casing arrangement. The heat exchangers are displaced within the compact casing arrangement. The refrigerant circuit is established for a combined refrigeration plant and heat pump operation as well as an afterheating operation, whereby in the afterheating operational mode the heating power of the afterheater established as condenser/gas cooler and the cooling power of the evaporator are controllable independently of each other.
