Abstract
A low-temperature showcase in which a double air curtain can be formed for commodity inlet-outlet opening provided in one side of its main body comprising: a heat exchanger in an inner passage being positioned upstream of and at a predetermined distance from another heat exchanger in an outer passage with respect to the same direction of air flows, a partition wall defining the inner and outer passages and having a first window at a portion thereof between the two heat exchangers, a closure plate for opening or closing the first window to close or open the inner passage downstream of the first window, and first control unit for giving instructions to the closure plate for its operation, the first control unit being operative to instruct the closure plate to open the first window and close the inner passage downstream of the first window when the heat exchanger in the inner passage is operated for defrosting with the heat exchanger in the outer passage operated for refrigeration, whereby the air flow through the heat exchanger in the inner passage is guided into the outer passage through the opened first window and cooled by being passed through the heat exchanger in the outer passage.
