Abstract
An evaporator coil system includes a segmented evaporator coil. The segmented evaporator coil includes a primary segment and a secondary segment. A first plurality of evaporator circuit lines are fluidly coupled to the primary segment and a second plurality of evaporator circuit lines are fluidly coupled to the secondary segment. A suction line includes a first connection fluidly coupled to the primary segment and a second connection fluidly coupled to the secondary segment. A valve is arranged in fluid communication with the secondary segment so as to selectively restrict refrigerant flow through the secondary segment.

17. A method of controlling a heating, ventilation, and air-conditioning (HVAC) system to regulate relative humidity, the method comprising:
-
measuring, via an HVAC controller, an operational time of the HVAC system; determining, via the HVAC controller, if the operational time exceeds a pre-defined run-time threshold; determining, via the HVAC controller, if a relative humidity of an enclosed space exceeds a pre-defined set point relative humidity; responsive to a determination that the operational time exceeds the pre-defined run-time threshold and the relative humidity of the enclosed space exceeds the pre-defined set point relative humidity, signaling a valve to close thereby restricting flow of refrigerant through a secondary segment of an evaporator coil; and responsive to a determination that the operational time does not exceed the pre-defined run-time threshold or the relative humidity of the enclosed space does not exceed the pre-defined set point relative humidity, signaling the valve to open thereby permitting flow of refrigerant through a secondary segment of an evaporator coil. - View Dependent Claims (18, 19, 20)
