System and method for conducting heating, ventilation, and air conditioning analytics

摘要

A system and method for conducting heating, ventilation, and Air Conditioning Analytics is disclosed. The system uses one or more wireless pneumatic thermostats (WPT) and/or various other sensors in communication with a control device to maintain, troubleshoot, calibrate, optimize, or otherwise adjust an installed pneumatic HVAC system.

主权项

1. A method for detecting a calibration offset error in one or more thermostats of a pneumatic thermostat HVAC system, each of the thermostats having a pressure sensor on a branch pressure line, the method comprising:
a. recording the ambient room temperature; b. calculating a theoretical neutral pressure; c. measuring a pressure reading from the pressure sensor; d. changing a setpoint on the pneumatic thermostat to a different value; e. repeating steps a through d for several setpoints; f. calculating a calibration error by analyzing the measured branch pressures compared to the theoretical neutral pressures based on setpoints and ambient temperatures.
