REFRIGERATED DEVICE WITH ENHANCED DEFROST AND CONDENSATE PAN HEATER CONTROL

Abstract:

A refrigerated device includes a compartment including an access door, and a door sensor for identifying an open condition of the access door. A refrigeration circuit for cooling the compartment includes an evaporator coil with an associated evaporator fan and a condenser with an associated condenser fan. At least one heat source is selectively activatable to provide heat. A controller is configured to selectively activate the heat source based upon an approximated an amount of water that enters the compartment during door open conditions.
