Abstract
Apparatus and a method for controlling refrigerant flow through the indoor coil of air conditioning equipment including a refrigeration system such that upon predetermined humidity conditions being sensed refrigerant flow will be routed to provide additional latent cooling and dehumidification. Within the liquid header of the indoor coil in the refrigeration system a solenoid valve is mounted to isolate at least one of a plurality of refrigerant circuits. This valve is closed when a need for dehumidification is detected by a humidistat located in communication with the air of the enclosure to be conditioned. When a need for dehumidification is not detected by the humidistat the valve is opened and refrigerant flows through all of the circuits of the indoor coil. Additionally, a check valve is mounted in parallel with the solenoid valve such that if a reversible refrigeration system is utilized refrigerant flow can bypass the solenoid valve in the heating mode of operation.
