Performance analysis and optimisation of the chiller-air handling units system with a wide range of ambient temperature

The integrated optimisation modelling for the chiller-air handling units system is developed for increasing the efficiency and energy utilisation of system. A building management system in the chillers network controls the cooling load to ensure the specified desired set temperature of the cooli...
