Indirect cooling of refrigerated vehicles

Cooling chambers (CC) (2,3) contain a heat exchanger (4) for vaporizing a refrigerating liquified gas (RLG), a phase breaker (20) for separating the RLG and gas formed from it, a heat exchanger for warming up gas formed from the RLG and a ventilator (6). The RLG and gas formed from it are spatially separated from the inner chamber of the CC. An independent claim is also included for a method for cooling one or more cooling chambers with refrigerating liquified gas.
