摘要
In a terminal reheat HVAC system which regulates the temperature in one or more temperature controlled spaces by modulating the temperature of cool discharge air presented to each of the spaces from an air handler source, each space receiving the cool discharge air though an associated space distribution unit which includes a heat source for reheating the cool air to provide temperature regulation within the space in response to a space temperature error signal from an associates space temperature control, electronic processing means is provided in combination with dedicated sensing apparatus to control the modulation of the cool air discharge temperature in response to temperature differences between space temperature reference signals stored in the electronic processing means and actual cool discharge air, and actual space temperature signals provided by the sensing apparatus. The electronic processing means further provides simultaneous, controlled actuation of the heat sources in each of the temperature controlled spaces in response to temperature differences between the actual sensed space temperature signal and the space temperature reference signals.
