Abstract

In a multi-circuit heat pump system least one of the circuits has a reheat function. Various reheat concepts may be independently utilized for each circuit to reheat and dehumidify air. Moreover, the ability to bypass refrigerant around the outdoor heat exchanger may also be provided. Communication means between the circuits may be present to re-optimize the refrigerant charge and to provide better control over system operational parameters. The above mentioned control functions and design features assure system flexibility in satisfying a wide spectrum of market requirements and potential applications by operation in a variety of cooling, heating and dehumidification regimes and a combination of thereof.
