An improved refrigeration system may include a first refrigeration loop or one to multiple units of split chillers providing cooling for HVAC, dehumidification, medium temperature load cases and further condensing the refrigerant utilizing a heat exchanger for the cascadable low temperature units. The system may be scalable and the distributive design utilizes chillers to replace the traditional rack system. The first refrigeration loop may incorporate an integral or remote pump(s) which provides coolant through conduits to the medium temperature cases, HVAC and low temperature heat exchangers. The system may further include a combined direct expansion condenser and free cooler system incorporating a partial, pre-chiller through the combination direct expansion, water, fluid (secondary) coolant condenser. This may allow for the water or fluids systems to be cooled by the ambient temperature and fans reducing the compressor run time or even allowing the compressors to turn off.

Refrigeration system and associated method

A non-compression cascade refrigeration system,for refrigerating a closed refrigerated space includes a cascade condenser,in heat exchange relationship with a primary evaporator,, a cascade evaporator,positioned in the refrigerated space,and a liquid and vapor separator,. A first coolant delivery conduit,delivers liquid coolant from the cascade condenser,to the separator,which then provides the coolant through a second coolant delivery conduit,to the cascade evaporator,for cooling the refrigerated space,. A first coolant return conduit,returns the coolant from the cascade evaporator,to the separator,where the return coolant is separated into liquid and gaseous coolant, such that the liquid coolant is directed to the second delivery conduit,for reuse in the cascade evaporator,and the gaseous coolant is directed to a second coolant return conduit,and returned to the cascade condenser
