Abstract
In a temperature control system for container vehicles, a refrigerant circuit has the customary compressor, condenser, expansion valve and evaporator. The compressor and condenser are together in one module while the expansion valve and evaporator are together in another module. The compressor is hydraulically driven. Heat for temperature control purposes can be obtained from the energy of the hydraulic fluid by means of a restrictor in the hydraulic fluid circuit.
