Abstract

A high-efficiency refrigeration system (10) with total heat reclaim capacity comprises one or more compressors (11) for compressing a refrigerant gas to a desirable operating pressure. A bi-directional valve (14) communicates the compressed gas from the compressor (11) to condensers (19) for cooling the gas, when required, or to heat reclaim coils (21-23) to extract heat from the gas for heating air locally. A modulating valve (40) adjusts the pressure of the refrigerant gas at the compressor (11) and dependent on a monitored parameter. A refrigerant liquid/gas reservoir (28) receives liquid and vapor gas from the condensors (19) and the heat exchange coils (21-23) independently from one another whereby these liquid refrigerants will mix freely in the reservoir (28). An outlet (45) of the refrigerant liquid/gas reservoir (28) is connected to an expansion valve at an inlet of the evaporators.
