A refrigeration unit (40) having a defroster (30) has a refrigeration compartment (44), an evaporator coil (26) having an amount of crystallized water being aggregated thereon from air and a thermo-electric module (32, 46, 48, 50) having a semiconductor material. The thermo-electric module (32, 46, 48, 50) provides heating from a first location of the thermoelectric module (32, 46, 48, 50) and cooling from a second location of the thermo-electric module (32, 46, 48, 50) based on a Peltier effect when a current from a power supply is traversed through the thermo-electric module (32, 46, 48, 50). The heating from a first location heats the evaporator coil (26) to defrost the aggregated amount of crystallized water thereon. The cooling from the second location is communicated to the refrigeration compartment (44).
