Refrigeration system and methods for refrigeration

A process for providing refrigeration to multiple locations in a facility, the method comprising steps of:

• (a) compressing a gaseous refrigerant from an accumulator to form a compressed gaseous refrigerant;
• (b) feeding the compressed gaseous refrigerant a plurality of decentralized condenser evaporator systems, the plurality of decentralized condenser evaporator systems each comprise:
• (1) a condenser for receiving the compressed gaseous refrigerant and condensing the compressed gaseous refrigerant to a liquid refrigerant;
• (2) a receiver for holding the liquid refrigerant;
• and
• (3) an evaporator for evaporating the liquid refrigerant from the receiver to form an evaporated refrigerant composition to provide refrigeration to one of the multiple locations in the facility;
• (c) feeding the evaporated refrigerant from the plurality of decentralized condenser evaporator systems to the accumulator, wherein the accumulator comprises a reservoir for storing the liquid refrigerant from the evaporated refrigerant composition;
• and
• (d) separating the evaporated refrigerant into the gaseous refrigerant and the liquid refrigerant, and storing the liquid refrigerant in the reservoir;
• and
• wherein the plurality of decentralized condenser evaporator systems operate independently or in conjunction to provide refrigeration to the multiple locations in the facility.
