1. A system for bringing a cabinet to a desired temperature and maintaining that desired temperature by heating or cooling the cabinet, comprising:

  • a first manifold for heat transfer fluid flow;

    at least one Peltier element in contact with the first manifold, such that a first heat transfer fluid can directly contact a first surface of the at least one Peltier element by flowing through the first manifold;

    at least a first fluid-to-air radiator in fluid communication with the first manifold and placed inside a cabinet;

    a second manifold for heat transfer fluid flow, the second manifold in contact with the at least one Peltier element, such that a second heat transfer fluid can directly contact a second surface of the at least one Peltier element by flowing through the second manifold; and

    at least a second fluid-to-air radiator in fluid communication with the second manifold and placed outside the cabinet;

    wherein application of current in a first direction to the at least one Peltier element generates heat that is transmitted to the at least a first fluid-to-air radiator to thereby heat an interior of the cabinet, and application of current in a second direction to the at least one Peltier element causes a reduction in temperature that is transmitted to the at least a first fluid-to-air radiator to thereby cool the interior of the cabinet as generated heat is transmitted to the at least a second fluid-to-air radiator for dispersal outside the cabinet.
