Patent ID: 7062930

Claim:
A method of providing humidity control to air for an interior space, the method comprising the steps of: providing a first refrigerant circuit having a first compressor, a first condenser and a first evaporator; providing a second refrigerant circuit having a second compressor, a second condenser and a second evaporator; providing a hot gas re-heat circuit connected to the first refrigerant circuit, the hot gas re-heat circuit having a re-heat coil positioned adjacent to the first evaporator, and the hot gas re-heat circuit being configured, when enabled, to bypass the first condenser and to permit refrigerant to flow from the first compressor through the re-heat coil to the first evaporator; enabling the first refrigerant circuit and the second refrigerant circuit in response to a demand for humidity control and a demand for cooling, wherein the demand for cooling is one of a demand for stage one cooling and a demand for stage two cooling; and enabling the hot gas re-heat circuit in response to a demand for humidity control and a demand for stage one cooling.
