A Heuristic Predictive Logic Controller Applied to Hybrid Solar Air Conditioning Plant

This paper shows the development of a heuristic predictive logic controller (HPLoC) applied to a solar air conditioning plant. The plant uses two energy sources, solar and gas, in order to warm up the water. The hot water feeds a single-effect absorption chiller. A hybrid controller using Model based Predictive Control (MPC) and heuristic logic conditions have been implemented in the real plant, the controller allows configuring the plant with the minimizing of the gas consumption.
