Abstract

A climate control system and method controls climate at selected regions within a passenger compartment of a vehicle. The thermoelectric system includes a plurality of thermoelectric assemblies. The system includes at least one fluid conduit configured to allow a liquid to flow in the at least one fluid conduit. The system further includes a plurality of thermoelectric assemblies. At least two thermoelectric assemblies of the plurality of thermoelectric assemblies are in thermal communication with the liquid and each of the at least two thermoelectric assemblies has a corresponding region within the passenger compartment. The at least two thermoelectric assemblies are selectively operable to transfer heat between the corresponding region and the liquid, wherein the at least two thermoelectric assemblies are each operable independently from one another.
