A refrigeration system for multi-temperature and single-temperature applications combines a refrigeration circuit and a single-phase fluid heat-transfer circuit in heat-conducting contact through a thermoelectric device. A vapor compression cycle provides a first stage of cooling and the thermoelectric device in conjunction with the heat-transfer circuit provides the second stage of cooling. Polarity of the thermoelectric device can be reversed to provide a defrost function for the refrigeration system.
What is claimed is: 1. A refrigeration system comprising: a thermoelectric device that forms a temperature gradient between first and second sides; a compressible working fluid flowing through a refrigeration circuit in heat-transferring relation to said first side of said thermoelectric device; a heat transfer fluid flowing through a heat-transfer circuit in heat-transferring relation to said second side of said thermoelectric device; wherein heat is extracted from one of said compressible working fluid and heat transfer fluid and transferred to the ot...
