Abstract

Systems and methods are disclosed that include providing a heating, ventilation, and/or air conditioning (HVAC) system with a controller that may adjust the defrost procedure algorithm by monitor the refrigeration coil temperature sensor and the ambient outdoor temperature sensor, calculate an Actual Coil Delta Temperature (ACDT); compare the calculated ACDT to an Initiate Delta Temperature (DTINIT) associated with the measured ambient outdoor temperature; initiate a defrost procedure in response to the calculated ACDT being greater than or equal to the DTINIT; determine if the duration of the defrost procedure is within a predetermined time threshold; and adjust the duration of a next defrost procedure in response to determining that a predetermined number of consecutive defrost procedures have occurred outside of the predetermined time threshold.
