Various refrigerant system schematics incorporate the ability to bypass refrigerant around a condenser, to selectively provide refrigerant of a desired thermodynamic state to downstream system components, including a reheat coil located downstream of the condenser. In addition, the reheat coil may be utilized in combination, or independently from an economizer cycle, that is also incorporated into the system design. The economizer branch can be configured in a sequential or parallel arrangement relative to the reheat coil. Consequently, a wide spectrum of sensible and latent load demands can be satisfied. Furthermore, various schematics provide distinct benefits and flexibility in unloading and temperature and humidity control, also resulting in system performance and reliability enhancement.

What is claimed is: 1. A refrigerant system comprising: a compressor for compressing refrigerant and delivering the refrigerant into a discharge line; a condenser downstream of said compressor for receiving refrigerant from said discharge line, and a condenser bypass line for communicating refrigerant from said discharge line around said condenser, a flow control device being positioned in said condenser bypass line, said condenser bypass line communicating back into said main refrigerant line at a junction point downstream of said condenser; a main expansion device downstream of said junction point, and an evaporator downstream of said main expansion device, said evaporator returning refrigerant back to said compressor; an economizer cycle incorporated into said refrigerant system, said economizer cycle including a tap line, a main economizer flow line, an economizer expansion device, and an economizer heat exchanger; and a reheat branch including a three-way valve for selectively communicating a refrigerant to a reheat coil downstream of said condenser, and an air moving device for passing air over said evaporator and at least a portion of said air over said reheat coil. 2. The refrigerant system as set forth in claim 1, wherein said three-way valve is positioned to communicate refrigerant from said main economizer flow line. 3. The refrigerant system as set forth in claim 2, wherein said three-way valve is positioned to be downstream of said economizer heat exchanger. 4. The refrigerant system as set forth in claim 3, wherein said main economizer flow line is positioned to be downstream of said return communication point of said condenser bypass line. 5. The refrigerant system as set forth in claim 3, wherein said main economizer flow line is positioned at a location intermediate of said condenser and said return communication point of said condenser bypass line. 6. The refrigerant system as set forth in claim 2, wherein said three-way valve is positioned to be upstream of said economizer heat exchanger. 7. The refrigerant system as set forth in claim 1, wherein said tap line for said economizer cycle is positioned to be downstream of said return communication point of said condenser bypass line. 8. The refrigerant system as set forth in claim 7, wherein said tap line is positioned to be in a return line from said reheat coil, returning refrigerant from said reheat coil back to said main refrigerant line. 9. The refrigerant system as set forth in claim 1, wherein said tap line communicates refrigerant from a location intermediate of said condenser and said return communication point of said condenser bypass line. 10. The refrigerant system as set forth in claim 1, wherein said economizer heat exchanger and said reheat coil are positioned to be in a parallel flow relationship with each other. 11. The refrigerant system as set forth in claim 1, wherein said economizer heat exchanger and said reheat coil are positioned to be in a sequential flow relationship with each other. 12.
