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.

1. A method of controlling operation of an HVAC system having actuator driven valves for adjusting the flow of fluid in the HVAC system and one or more sensors for sensing operational parameters of the HVAC system, the method comprising:
transmitting sensed operational parameter values from the one or more sensors via a telecommunications network to a cloud-based HVAC control center; calculating in the cloud-based HVAC control center control values for the actuators, using the sensed operational parameter values from the one or more sensors and calibration values stored in the cloud-based HVAC control center, the calibration values indicating operational parameters of the HVAC system at defined conditions in the HVAC system; and transmitting the control values for the actuators from the cloud-based HVAC control center to the actuators.
