Abstract
A heating, ventilation and air conditioning system (200) reduces energy consumption in a building (202) by turning on and off all compressors (212, 214, 216). The HVAC system (200) includes a plurality of in-flow air temperature sensors (232, 234, 236) and out-flow air temperature sensors (242, 244, 246) that respectively measure return air temperatures at inlets and supply air temperatures at outlets of fan coil units (222, 224, 226) located in rooms (203, 205, 207) of the building (202). The HVAC system (200) turns on and off all the compressor (212, 214, 216) based on the return air temperatures and the supply air temperatures.
