A tandem compressor system is utilized that receives refrigerant from a common suction manifold, and from a common evaporator. From the compressors, the refrigerant passes to a plurality of condensers, with each of the condensers being associated with a separate zone for heat rejection, preferably at different temperature levels. Each of the condensers is associated with at least one of the plurality of compressors. A reheat coil is associated with the evaporator to improve comfort level in the environment to be conditioned. Multiple reheat circuits associated with separate condensers are employed to provide various stages of reheat or to condition separate environments. By utilizing the common evaporator, a plurality of condensers, and the reheat coils, the ability to independently control temperature, humidity and amount of heat rejection to a number of zones is achieved without the requirement of having dedicated circuits with multiple additional components. Thus, the overall system cost and complexity is significantly reduced and its operational and control flexibility is improved.
