Method for controlling operation of an HVAC system

摘要

For controlling the flow of air into the zones (Z1, Z2, Z3, Zi) of a variable air volume HVAC system (1) having actuator driven dampers (D1, D2, D3, Di), which operate in a range from a minimum damper position to a maximum damper position for adjusting the flow of air into a zone (Z1, Z2, Z3, Zi), flow measurement values and current damper positions are transmitted via a telecommunications network (2) to a cloud-based HVAC control center (3). Using the flow measurement values and calibration values, which indicate HVAC system parameters at a defined calibration pressure in the HVAC system (1) and at different damper positions, the cloud-based HVAC control center (3) calculates the minimum damper position for the actuators (A1, A2, A3, Ai), such that the pressure in the HVAC system (1) does not exceed a defined maximum pressure threshold, and transmits the minimum damper position to the actuators.
