  • Control system for efficient intermittent operation of building HVAC equipment
    Patent number: 4475685
    Abstract: A system of determining optimum start/stop times for HVAC equipment in a building utilizes quantized inside and outside air temperature values as the controlling data input. Lead-times necessary to achieve the desired control temperatures, given input and output temperature levels are stored in a matrix in a central processor storage. System performance is monitored and results are used to modify the lead-times so that the operating system can more closely achieve the desired results.
