Abstract: In the present scenario free cooling system is one effective solution for reducing the power consumption of air conditioning systems. Various free cooling methods are available for data centers and commercial buildings that eliminate or reduce the need for mechanical cooling by utilizing outdoor air under certain conditions. It is evident that climate conditions affect the performance of free cooling modes. It also affects the performance of main components of the cooling infrastructure indirectly due to inefficiencies caused by the part load operation during free cooling modes. Hence, modeling key components of cooling infrastructure in an essential element for reliable assessment of these methods. Most of the studies assessing energy saving potential of free cooling methods in the existing literature follow simpler approaches that do not consider the off-design performance of cooling equipment.
