摘要： A refrigerant circuit is configured, which includes an electric compressor, a condenser, an expansion mechanism, an evaporator, a hot gas introduction path connecting the electric compressor and the evaporator together, and a switching valve for controlling a flow of refrigerant in the hot gas introduction path. In addition, a fan is provided. In a defrosting cycle for introducing refrigerant into the evaporator through the hot gas introduction path to defrost the evaporator, if the pressure of the condenser is equal to or lower than a predetermined threshold, the fan forms an air flow from a radiator to the condenser.

摘要： A refrigeration apparatus (10) includes: a refrigerant circuit (20) provided with a variable-opening expansion valve (13); and a valve control means (33) for controlling the opening of the expansion valve (13) by outputting to the expansion valve (13) an opening command value equal to or larger than a lower limit command value. During operation of a refrigeration cycle and in a lower-limit-controlled state in which the opening command value is equal to the lower limit command value, the valve control means (33) performs a first determination operation of determining whether the refrigerant flow through the expansion valve (13) is in an excessively large amount state or not based on a condition of refrigerant between the expansion valve (13) and the suction side of a compressor (11), and corrects the lower limit command value to a smaller value if the determination result in the first determination operation is that the refrigerant flow through the expansion valve (13) is in an excessively large amount state.

摘要： Cooling operation is performed so as to keep a freezer at a selected temperature. Moreover, if the cooling operation enters a phase where the freezer temperature is higher than the selected temperature by a predetermined deviation or more, not only the deviation temperature but also an accumulated time obtained by accumulating the time periods during which the cooling operation is performed at the deviation temperature or higher are stored. In addition, when an instruction signal to indicate an accumulation is input, the stored accumulated time and deviation temperature are read out and indicated on a segment indicating section (7S).

摘要： The refrigeration system has an energy saving operation mode performing: a first action in which a compressor (11) and an internal fan (16) are driven while the cooling capacity of an evaporator (14) 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 (14) 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 (11) and the internal fan (16) 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 (16) is activated at a lower air flow rate than in the first action.

摘要： When during a first action of a refrigeration system the internal cold storage temperature is held at a desired temperature by an evaporator, the refrigeration system performs a second action of increasing the cooling capacity of the evaporator to decrease the internal cold storage temperature. When during the second action the internal cold storage temperature reaches a minimum temperature Tmin, the refrigeration system stops a compressor and performs a third action. When during the third action the internal cold storage temperature reaches a maximum temperature Tmin, the refrigeration system drives the compressor and performs the first action.
