Abstract

A refrigerant system incorporates a hot gas reheat circuit. The hot gas reheat circuit includes a reheat valve for selectively tapping at least a portion of refrigerant from a location downstream of a compressor and upstream of a condenser, and through a reheat heat exchanger. At least one refrigerant flow control device controls the amount of refrigerant passing through the reheat heat exchanger. A control for the refrigerant system is operable to receive inputs from an indoor environment, and to control the amount of refrigerant passing through the reheat heat exchanger to achieve desired temperature and humidity in the conditioned environment.
