ABSTRACT:
Multi-circuit refrigerant systems are provided with better control over a dehumidification function. In one embodiment, system circuits have means of communication with each other through connecting lines and flow control devices operable on demand. In another embodiment, a single reheat heat exchanger is utilized for both circuits, ensuring heat transfer interaction between the circuits. In yet another embodiment, a control unit operates refrigerant circuits in such a way that if some circuits are in a reheat mode, the remaining circuits are either shut off or are in an enhanced reheat mode.
