Heat recovery optimization of a shell and tube bundle heat exchanger with continuous helical baffles for air ventilation systems

International Journal of Air-Conditioning and Refrigeration
We report a numerical evaluation of the impact of continuous helical baffle on the heat recovery efficiency of counterflow tube bundle heat exchangers. The baffle inclination angle has been varied from $$11^{\circ }$$ 11 ∘ to $$22^{\circ }$$ 22 ∘ . Since

Adaptive neural network control of a centrifugal chiller system

International Journal of Air-Conditioning and Refrigeration
In this paper, a neuro-adaptive PI control strategy for a water-cooled centrifugal chiller system is developed, and its control performance is examined. The system model consists of a flooded evaporator, a flooded condenser, a centrifugal compressor, and
