Systems and Methods for Drain Pan Pulse Heating

A method comprising:

• receiving, by a controller of a refrigeration system and at a first time, first data from a sensor disposed in a drain pan of an evaporator of the refrigeration system, the first data indicative of a first temperature of the drain pan;
• determining, by the controller, that the first temperature fails to satisfy a first temperature setpoint;
• activating, by the controller and based on determining that the first temperature fails to satisfy the first temperature setpoint, a heating element disposed within the drain pan;
• receiving, by the controller, second data from the sensor at a second time, the second data indicative of a second temperature of the drain pan;
• determining, by the controller, that the second temperature fails to satisfy a second temperature setpoint;
• and
• de-activating, by the controller and based on determining that the second temperature fails to satisfy the second temperature setpoint, the heating element.

A non-transitory computer-readable medium storing computer-executable instructions which, when executed by a processor, cause the processor to perform operations comprising:

• receiving, at a first time, first data from a sensor disposed in a drain pan of an evaporator of a refrigeration system, the first data indicative of a first temperature of the drain pan;
• determining that the first temperature fails to satisfy a first temperature setpoint;
• activating, based on determining that the first temperature fails to satisfy the first temperature setpoint, a heating element disposed within the drain pan;
• receiving second data from the sensor at a second time, the second data indicative of a second temperature of the drain pan;
• determining that the second temperature fails to satisfy a second temperature setpoint;
• and
• de-activating, based on determining that the second temperature fails to satisfy the second temperature setpoint, the heating element.
