Abstract
The refrigeration system has an energy saving operation mode performing: a first action in which a compressor () and an internal fan () are driven while the cooling capacity of an evaporator () is regulated; a second action in which, when the blow-off-side air temperature in a cold storage is kept at a set value in the first action, the cooling capacity of the evaporator () is increased to lower the blow-off-side air temperature to a lower limit temperature of a desired temperature range containing the set value and the compressor () and the internal fan () are then stopped; and a third action in which, when the blow-off-side air temperature after the second action rises to an upper limit temperature of the desired temperature range, the first action is restarted. Furthermore, the energy saving operation mode is configured so that when the suction-side air temperature in the cold storage after the second action rises to a limit value, the internal fan () is activated at a lower air flow rate than in the first action.
