Abstract
A method, and related refrigerated device, is provided for controlling a heater element of a refrigerated device having a compartment including an access door engageable with a perimeter of a compartment opening when the door is closed and a refrigeration circuit for cooling the compartment to a set point temperature, wherein the heater element heats a surface of the perimeter of the compartment opening to inhibit formation of condensation on the surface. The method involves: determining a temperature and relative humidity of ambient air surrounding the refrigerated device; determining a dew point temperature of the ambient air based upon the temperature and the relative humidity of the ambient air; and defining an energization level for the heater element based at least in part upon each of (i) the determined dew point temperature, (ii) the temperature of the ambient air and (iii) the set point temperature of the compartment.
