Summary

TWO PARALLEL COOLING COILS ARE LOCATED IN A CABINET. WHILE ONE COIL IS UNDER COOLING, THE OTHER COIL IS BEING DEFROSTED BY THE HOT LIQUID REFRIGERANT, ENTERING INTO THE CABINET. AIR CIRCULATES ONLY THROUGH A COOLING COIL BY SHIFTING A SHUTTER LOCATED IN THE AIR CIRCUIT. LIQUID REFRIGERANT ENTERS FIRST INTO THE DEFROSTING COIL, THEN ENTERS INTO THE COOLING COIL THROUGH A SOLENOID VALVE AND AN EXPANSION VALVE. SHIFTS OF SHUTTER AND SOLENOID VALVES ARE CARRIED OUT AUTOMATICALLY BY A SOLID STATE CONTROLLER LOCATED IN THE CABINET. CONSTANT PRODUCTS TEMPERATURE AND LOWER ENERGY CONSUMPTION CAN BE ACHIEVED DUE TO NO PULLDOWN OPERATIONS.
