Abstract
A condenser evaporator system includes: a condenser constructed for condensing a gaseous refrigerant from the source of compressed gaseous refrigerant; a controlled pressure receiver for holding liquid refrigerant; a first liquid refrigerant feed line for conveying liquid refrigerant from the condenser to the controlled pressure receiver; an evaporator for evaporating liquid refrigerant; and a second liquid refrigerant feed line for conveying liquid refrigerant from the controlled pressure receiver to the evaporator. The condenser evaporator system can be provided as multiple condenser evaporator systems operating from a source of compressed gaseous refrigerant.
