Available in PDF, EPUB and Kindle. Book excerpt: A study to investigate the use of adaptive and optimal control techniques to control HVAC systems in large solar heated and cooled buildings is reported. The study has been made by computer simulation and is centered on the National Security and Resources Study Center (NSRSC), a large solar heated and cooled building at the Los Alamos Scientific Laboratory (LASL). Although the study is based on a specific building the results are completely general. Simplified models of the building and HVAC system have been developed for both the heating and cooling modes. The control strategies actually used in the NSRSC were simulated in the models and an adaptive optimal controller was developed and also simulated. Simulation runs were made with both the conventional controller and the adaptive controller and performance of the two simulations were compared. It was found that the adaptive optimal controller model demonstrated a savings in auxiliary energy of 28.8% for the heating simulation and 20.2% for the cooling simulation when compared to the conventional controller simulation models.

Book excerpt: The use of adaptive control techniques is investigated in heating, ventilating, and air cnditioning (HVAC) systems in solar heated and cooled buildings to minimize the consumption of auxiliary energy. Optimal control theory is used in conjunction with the adaptive control techniques to accomplish the minimization of auxiliary energy. The resulting technique is referred to as adaptive optimal control (AOC). This study has been made by computer simulation and is centered on the National Security and Resources Study Center (NSRSC), a large solar heated and cooled building at the Los Alamos Scientific Laboratory (LASL). Simplified models of the building and HVAC system have been developed for both the heating and cooling modes. The control strategies actually used in the NSRSC were simulated in the models and an adaptive optimal controller was developed and also simulated. Simulation runs were made with both the conventional controller and the adaptive controller and performance results of the two simulations were compared. In the first results (obtained using a partial derivative system identification method), the adaptive optimal controller model demonstrated a savings in auxiliary energy of 28.8% for the heating simulation and 18.3% for the cooling simulation when compared to the conventional controller simulation models.

Available in PDF, EPUB and Kindle. Book excerpt: Identification and optimal control techniques are combined to form an adaptive optimal control strategy which is used to minimize the auxiliary energy consumption for a solar heated building. The adaptive optimal control strategy is described and application of the adaptive optimal controller to the heating, ventilating, and air conditioning (HVAC) system in an appropriate building is modeled. The building used is the newly completed National Security and Resources Study Center (NSRSC) at the Los Alamos Scientific Laboratory (LASL). The NSRSC uses an 8000 sq. ft. solar collector to provide energy for heating and cooling the building. A cost functional to define optimal performance of the HVAC system and an identification process to produce a linearized building model are combined to yield an adaptive linear regulator solution. Although solar energy is used for both heating and cooling the NSRSC, only the results from the heating simulation are available for presentation here. Energy savings predicted by the model when compared to a conventional control system are described and an alternate system configuration is briefly discussed. Plans for actual implementation of the adaptive optimal controller are discussed.
