Abstract: A method of operating an air conditioner unit to implement effective defrost cycles includes obtaining a coil temperature of an outdoor heat exchanger, a dew point of a flow of air through the outdoor heat exchanger, and a flow rate of the flow of air. A frost rate of frost buildup on the outdoor heat exchanger is estimated based on the coil temperature, the dew point, and the flow rate, and a frost quantity or weight is determined by integrating the frost rate. A defrost cycle is initiated if the frost quantity exceeds a predetermined frost threshold, e.g., in pounds of water.

Abstract: An air conditioning system and a method of operating the same to dehumidify air from an indoor space without overly cooling that air is provided. The air conditioning system includes an outdoor heat exchanger, an indoor heat exchanger, and a reheat heat exchanger. Indoor air passes through the indoor heat exchanger where it is dehumidified before passing through the reheat heat exchanger where it is reheated using thermal energy from a refrigerant. An outdoor fan urges a flow of ambient air through the outdoor heat exchanger to extract thermal energy from the refrigerant before it passes to the reheat heat exchanger. The speed of the outdoor fan is adjusted to control an amount of thermal energy extracted from a refrigerant passing through the outdoor heat exchanger and thus the thermal energy supplied to the reheat heat exchanger for reheating the dehumidified air to a target temperature.
