  • Adaptable control of HVAC systems
    Patent number: 5170935
    Abstract: A system for providing adaptable control of an HVAC system which regulates environmental conditions within an enclosed area. In a preferred embodiment, the apparatus and method of the present invention measures selected environmental variables in the enclosed area, calculates a value of a comfort index which is a function of the values of the selected environmental variables and a plurality of parameters that predicts a thermal sensation rating of an occupant. The system receives an actual thermal sensation rating from the occupant and compares the predicted thermal sensation rating with the actual thermal sensation rating to determine a difference between the predicted thermal sensation rating and the actual thermal sensation rating.
