Abstract:
1. A refrigerant cycle comprising: a compressor for compressing a refrigerant, and delivering the refrigerant to a condenser, a main expansion device downstream of said condenser, and an evaporator downstream of said main expansion device; an economizer heat exchanger for receiving a main refrigerant flow, and a tapped refrigerant flow, said tapped refrigerant flow passing through an economizer expansion device, and said tapped refrigerant flow cooling said main refrigerant flow in said economizer heat exchanger; a reheat coil for receiving at least a portion of a refrigerant flow at a temperature above a temperature of the refrigerant reaching said evaporator, said reheat coil being positioned downstream of said economizer heat exchanger; and an air moving device for driving air over said evaporator and said reheat coil, such that air may be cooled and dehumidified by passing over said evaporator and then be reheated by said reheat coil.
