COOL AIR ACCUMULATING UNIT FOR EVAPORATOR

摘要

PURPOSE: A condensed cool air unit for an evaporator is provided to reduce electricity consumption and preserve freezing goods by accumulating cool air and discharging in the daytime with driving a refrigerating cycle at night, and to lengthen a life span of a compressor by reducing operation time. CONSTITUTION: A cool air accumulating unit is composed of a condensed air plate(10) having a closed space to accumulate cool air and recessed grooves(11) at both sides; a refrigerant pipe(20) arranged in the condensed air plate; a cool air condensing agent and refrigerant filled in the condensed air plate and the refrigerant pipe; a defrosting heater pipe(50) fitted to the recessed grooves; and a cool air condensing agent injection port(60) installed at the side of the condensed air plate and sealed. The cool air is accumulated with freezing the cool air condensing agent in driving a compressor at night. The cool air is discharged to the refrigerator through the fan with evaporating slowly in liquefying latent heat in the daytime or at power-off. The freezing state is kept for a long time without driving the compressor.
