CONTROL DEVICE FOR SHOWCASE

摘要

PROBLEM TO BE SOLVED: To correctly and efficiently control temperature of goods displayed in a showcase of which inner parts are visible from the outside. SOLUTION: A low temperature showcase 1a is provided with a storage chamber 39 of which inner parts are visible from the outside. Cold air heat-exchanged with an evaporator 46 is discharged to the storage chamber 39, so that goods displayed in the storage chamber 39 is cooled. Cooling operation by the evaporator 46 is controlled based on temperature of discharged cold air discharged to the storage chamber 39 and set temperature of discharged cold air. Based on enthalpy of external environments of the low temperature showcase 1a, the set temperature is risen when the enthalpy is lowered. COPYRIGHT: (C)2005,JPO&NCIPI
