Abstract

PURPOSE: To shorten the defrosting time and to restrict temperature rise in an open display case by controlling the operation of a fan to reduce the air velocity as compared with cooling time and forming an air curtain for preventing atmospheric air from entering the front of the case to thereby restrict dissipation of defrosting sensible heat.
CONSTITUTION: A blower 5 is controlled by switching a blower motor between high and low revolutions in cooperation with a thermostat operating at the detected temperature of an evaporator 4 or a timer. When cooling operation is switched to defrosting operation, the blower 5 is switched to low revolution to thereby reduce the air velocity passing through the evpaorator 4. Accordingly, it reduces the defrosting time due to the reduction of dissipation of the sensible heat for heating the evaporator 4 into the air. It cools less than cooling operation during this period, but blows minimum air curtain A' to the front of the case so as to prevent the atmospheric air from entering the front of the case
