Title:
OPERATION CONTROL DEVICE FOR FREEZER DEVICE
Document Type and Number:
Japanese Patent JP2643671
Kind Code:
B2
Abstract:
PURPOSE: To prevent an over-cooling of a spacing to be air conditioned caused by a temperature distribution of a blown air temperature of an evaporator.
CONSTITUTION: In a freezer device comprising a compressor 1, a condensor 2, an expansion valve 3 and an evaporator 4 connected in series to form a refrigerant circuit 6, each of locations of air blowing ports corresponding to each of the locations of the evaporator 4 ranging from a flow divider 12 to a header 13 is provided with a plurality of temperature sensors Th1 to Th5. The temperature sensors Th1 to Th5 having the lowest detected value are selected as control sensors by a sensor selecting means 21 and further a capability of the evaporator 4 is controlled in response to the detected value of the control sensor by a capability control means 20. With such an arrangement, a blowing air temperature is always controlled in response to the minimum value of the blowing temperature so as to prevent an over-cooling of a spacing to be air conditioned.
