초록

A control system for a HVAC unit for controlling the humidity and temperature of interior building space at desired levels regardless of the outside temperature and humidity conditions. This system is more efficiently so that it operates with less energy consumption than current HVAC systems. The control system employs a combination of modulated return air bypass, modulated capacity compressor, and modulating hot gas reheat to maintain proper interior space humidity, and temperature while maintaining adequate ventilation within the interior building spac...
