US 10,948,209 B2 · Monitoring system for residential HVAC systems

Abstract

A system and method for controlling HVAC equipment in a residential setting. The system may include an outdoor temperature sensor positioned to measure outdoor temperatures, an indoor air temperature sensor to measure indoor space air temperatures, a supply duct air temperature sensor positioned to measure supply duct air temperatures, a return duct air temperature sensor positioned to measure return duct air temperatures, an air blower current sensor positioned to measure air blower currents, and/or an air compressor current sensor positioned to measure air compressor currents, and a controller operable to receive the measures of outdoor temperature, indoor space air temperature, supply duct air temperature, return duct air temperature, air blower current, air compressor current, and measures of solar irradiation intensity and wind speed. The controller may be programmed with instructions to input the measures into a thermal model for outputting signals for implementing changes in the system.
