A modular thermoelectric cooling/heating unit is installed through an opening in a wall separating first and second temperature zones. This modular thermoelectric cooling/heating unit comprises a thermoelectric devic e including a cold surface, a hot surface, and a cooling/heating member between an electrical power supply and the cold and hot surfaces. A heat conducting block has a proximal end for thermally contacting with a first on e of the cold and hot surfaces, and a distal end. A first heatsink thermally contacts with a second one of the cold and hot surfaces, a second heatsink thermally contacts with the distal end of the heat conducting block, and a thermally insulating housing covers at least a portion of the heat conductin g block between the proximal and distal ends of this block. In operation, the first heatsink is located in the first temperature zone, at least a portion of the heat conducting block and the thermally insulating housing extend through the wal l opening, and the second heatsink is located in the second temperature zone. The above described modular thermoelectric cooling/heating unit can be us ed in a modular cooling system for retrofit into an existing refrigeration unit .
