Patent ID: 8544283

Claim:
A condenser evaporator system comprising: (a) a condenser constructed for condensing a gaseous refrigerant provided at a condensing pressure; (b) a gaseous refrigerant feed line for feeding gaseous refrigerant to the condenser; (c) a controlled pressure receiver for holding liquid refrigerant; (d) a first liquid refrigerant feed line for conveying liquid refrigerant from the condenser to the controlled pressure receiver; (e) an evaporator for evaporating liquid refrigerant; and (f) a second liquid refrigerant feed line for conveying liquid refrigerant from the controlled pressure receiver to the evaporator, wherein the condenser evaporator system is constructed so that the condenser and the evaporator are balanced during a refrigeration cycle, and wherein the condenser evaporator system is constructed to operate in a refrigeration cycle and in a defrost cycle.
