VARIABLE AIR VOLUME HVAC SYSTEM CONTROLLER

摘要

A variable air volume heating, ventilation and air conditioning (HVAC) system controller (300) with adaptive control architecture adjusts control parameters to provide for increased direct expansion coil air flow (14) and reduced compressor cycling (326). The supply air temperature set point (Tsa) is adjusted as a function of the return air temperature (Tra) and compressor cycling is time limited.
