A thermoelectric heat transfer system is provided. The thermoelectric heat transfer system comprises a coolant circuit with a pump circulating coolant through the circuit. A first heat exchanger is in fluid communication with the coolant circuit to remove heat from the coolant. At the same time, a second heat exchanger is in fluid communication with the coolant circuit. Thermoelectric modules (TEMs) are integrated into the second heat exchanger to create a temperature differential between fins and conduits of the second heat exchanger. The coolant flows through the conduits to draw heat from the TEMs, while a fan assembly conveys air through the fins into a climate-controlled area to cool the climate-controlled area to a desired temperature. In other embodiments, a sleeve acts as the second heat exchanger. The sleeve is adapted to receive and cool beverage containers and like items.
