PROBLEM TO BE SOLVED: To provide a low temperature storage shed allowing detection of clogging-up of a filter, and allowing detection of a lock (abnormality) of a blower for a condenser. SOLUTION: This low temperature storage shed has: a refrigerant circuit comprising a compressor, the condenser and an evaporator; the blower for the condenser cooling the condenser; the filter disposed on an air suction side of the condenser; a discharge temperature sensor detecting discharge temperature of the condenser; a machine room storing the refrigerant circuit, the blower, the filter and the discharge temperature sensor; an outside air temperature sensor detecting a temperature of the machine room; and a controller controlling operation of the compressor and the blower on the basis of output of the discharge temperature sensor and/or the outside air temperature sensor. The controller notifies the clogging-up of the filter when a detection temperature of the discharge temperature sensor is a first reference temperature or above, and stops the compressor when the detection temperature is a second reference temperature higher than the first reference temperature, or above.
