Abstract (en)

[origin: WO2007024237A1] A refrigerant system is provided with a reheat circuit. A pulse width modulation control is provided to achieve variable reheat capacity and thus to satisfy a wide spectrum of temperature and humidity levels in an environment conditioned by a refrigerant system. The pulse width modulation signal provided for the reheat flow control device achieves incremental amounts of reheat while avoiding temperature and humidity variations in the conditioned space.
