Strategic modular commercial refrigeration

A modular food store refrigeration system comprising:

• at least two refrigerated fixtures having first closely adjacent locations in the store, a first stage evaporator coil for cooling each of the refrigerated fixtures to maintain food products therein within a predetermined temperature range;
• at least two multiplexed scroll type first stage compressors having a second location in the store in closely adjacent proximity to the first locations of the refrigerated fixtures, and first stage condenser means connected together with said first stage compressors and said first stage evaporator coils to form a first stage closed loop refrigeration circuit;
• an exterior heat exchange device located in a remote environment outside the store for transferring heat to the exterior atmosphere;
• and a closed liquid heat transfer loop extending between the first stage closed loop refrigeration circuit and the remote environment and interconnecting the exterior heat exchange device and the first stage condenser means in continuous communication to transfer heat from the first stage condenser means to the exterior heat exchange device.
