摘要： Provided is a land-transport refrigeration system that can maintain a reduced fuel consumption effect even when operating under a multi-evaporator-type automatic start-stop operation mode. The system includes a compressor (5) driven by an engine (7); a plurality of evaporator units disposed respectively in cargo compartments (3A, 3B, and 3C) and parallel-connected to a refrigerant circuit (17) through which a refrigerant circulates; and a controller (15) having an automatic start-stop operation mode (27) that stops the operation of the compressor (5) or the evaporator units when set temperatures are reached and that resumes the operation of the compressor (5) or the evaporator units when operation-regaining temperatures set to be higher than or lower than the set temperatures by a predetermined temperature are reached. The automatic start-stop operation mode (27) includes a thermostat-off-condition retaining operation that prevents the temperature in the cargo compartment having reached the corresponding set temperature from reaching the corresponding operation-regaining temperature until all the cargo compartments (3A, 3B, and 3C) reach their respectively set temperatures.
