Claim Text:
1. A refrigeration system for a facility comprising: (a) a compressor arrangement for compressing gaseous refrigerant from a first pressure to a second pressure, wherein the second pressure comprises a condensing pressure; (b) a first condenser evaporator system and a second condenser evaporator system, wherein the first condenser evaporator system and the second condenser evaporator system are arranged in parallel and each comprises: (1) a condenser for receiving the gaseous refrigerant at the condensing pressure and condensing the gaseous refrigerant to a liquid refrigerant; (2) a controlled pressure receiver for holding the liquid refrigerant from the condenser; and (3) an evaporator for evaporating the liquid refrigerant from the controlled pressure receiver to form the gaseous refrigerant; (c) a first gaseous refrigerant feed line for feeding the gaseous refrigerant at the second pressure from the compressor arrangement to the first and second condenser evaporator systems; and (d) a second gaseous refrigerant feed line for feeding the gaseous refrigerant from the first and second condenser evaporator systems to the compressor arrangement; (e) the evaporator of the first condenser evaporator system and the evaporator of the second condenser evaporator system are constructed to provide refrigeration to the facility, and wherein the refrigeration system is constructed so that the compressor arrangement feeds gaseous refrigerant to both the first condenser evaporator system and the second condenser evaporator system simultaneously; and wherein the refrigeration system is constructed so that the first condenser evaporator system and the second condenser evaporator system can operate at the same time to provide refrigeration to the facility at the same time.
