Abstract
A heat pump system operates in heating and cooling modes. The heat pump is provided with both a reheat function and economizer circuit. The economizer circuit provides augmented performance to the heat pump, while the reheat coil allows enhanced control over temperature and humidity of the air supplied to the conditioned space. A bypass line around an outdoor heat exchanger is also provided to achieve additional flexibility of control for a sensible heat ratio. Selective operation of the abovementioned components and subsystems allows precise control over system operation parameters and hence satisfaction of a wide spectrum of sensible and latent load demands and improved reliability.
