Optimization of heating and cooling of a building by employing refuse and renewable energy

For an installation for the heating and cooling of a building that uses refuse and renewable energy, electrical energy savings may be high without any computer control. However, energy savings may be even higher when this installation is with computer control. In this case, the installation uses different types of refuse and renewable energy in real time, that yield the minimum energy consumption. To confirm this proposition, this paper presents a yearly simulation of the operations of an installation for heating and cooling with and without computer control. The installation consists of four devices employing refuse and renewable energy: an air-to-air heat pump (HP), heat-recovery exchanger (HRE), air-to-earth heat exchanger (ATE), and air-mixing device (MD). The installation is modelled by using bottom-up procedures, energy-module network, and dynamic programming. (C) 2000 Elsevier Science Ltd. All rights reserved.
