1. A method for cooling an area using a cooling system, the method comprising:

  • circulating a working fluid through a heat sink heat exchanger adapted to cool the working fluid;

    circulating the working fluid through a feedback heat exchanger in fluid communication with the heat sink heat exchanger;

    transferring energy between the working fluid and a second fluid to condition the second fluid to reach a desired temperature;

    directing the working fluid to a thermoelectric device disposed between and in fluid communication with the heat sink heat exchanger and the feedback heat exchanger, the thermoelectric device configured to heat the working fluid and cool the second fluid to a temperature lower than the desired temperature; and

    transferring energy between the working fluid and the second fluid using the feedback heat exchanger to increase a coefficient of performance of the thermoelectric device.
