چکیده

A data-mining approach is applied to optimize the energy consumption of an air handling unit. A multiperceptron ensemble algorithm is used to model a chiller, a pump, and the supply and return fans. A non-linear model is developed to minimize the total energy consumption of the air-handling unit while maintaining the temperature of the supply air and the static pressure in a predetermined range. A dynamic, penalty-based, electromagnetism-like algorithm is designed to solve the proposed model. In all, 200 test data points are used to validate the proposed algorithm. The computational results show that the energy consumed by the air-handling unit is reduced by almost 23%. © 2013 Elsevier B.V. All rights reserved.

Model-Based Diagnostics for Air Handling Units

Introduction In most large air-conditioned buildings, air-handling units account for a significant portion of total building energy consumption and have a major impact on comfort conditions and maintenance costs. The devices within an air-handling unit either use energy directly in the case of fans, or indirectly, in the case of heat exchangers, which impose loads on the chiller and boiler plan...

A Bayesian Approach for Predicting Building Cooling and Heating Consumption

This research proposes a Bayesian approach to include uncertainty that arises from modeling process and input values when predicting cooling and heating consumption in existing buildings. Our approach features Gaussian Process modeling. We present a case study of predicting energy use through a Gaussian Process and compare its accuracy with a Neural Network model. As an initial step of applying...
