The second coolant storage forms a second coolant circulating path with the first coolant storage and is capable of supplementing the first coolant storage with the coolant. The capacity of the second coolant storage is larger than that of the first coolant storage. The first airflow drive cooperates with the first heat exchanger to direct and eject the air flowing through the first heat exchanger.

The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) system having a heat exchanger configured to thermally regulate a supply air flow, where the heat exchanger includes a thermoelectric device, a first plurality of fins coupled to the thermoelectric device, and a second plurality of fins coupled to the thermoelectric device. The first plurality of fins extend into a supply air flow path of the supply air flow to transfer thermal energy between the thermoelectric device and the supply air flow and the second plurality of fins convectively transfer thermal energy between the thermoelectric device and a working fluid exterior the supply air flow path.

A cooling system for a photovoltaic panel including micro flat heat pipes (HP) integrated with thermoelectric generators (TEG) and a cooled water reservoir for cooling the working fluid in heat pipes. The cooled water in the reservoir is pumped from the condensate pan of an air conditioner. Experimental results show that cooling system reduced the average temperature of the panel by as much as 19° C. or 25%. Further, the output power of the photovoltaic panel increased by 44% when the photovoltaic panel was used in a very hot climate (30-40° C.). An additional two watts of power was generated by the TEGs.
