ABSTRACT:
An economizer loop is incorporated into the refrigerant system, which in conjunction with any selected reheat mode of operation, provides augmented performance, improved reliability, and enhanced control in meeting external heat load demands. A refrigerant system includes several features that can be selectively utilized alone or in combination with each other to provide an enhanced control over system cooling and dehumidification capability. In particular, a reheat coil is incorporated into the refrigerant system, and has alternative connection points to the main circuit, positioned both upstream and downstream of a condenser. Also, a flow control device allows a selective bypass around a condenser. In this manner, the refrigerant flowing through the reheat coil can be controlled to provide a desired level of temperature and humidity. Finally, the compressor may include an unloader feature such that additional steps in capacity control can be provided.
