Return water bypasses the chillers and goes from the cooling towers directly to a heat exchanger when the wet-bulb temperature of the outdoor air is below 6.1 ˝C. The temperature of the return water is decreased to close to the wet-bulb temperature of the outdoor air by the cooling ...
Optimization Objectives • Natural Ventilation Effectiveness (NVE) The number of hours the outdoor airflows can be used to cool space is estimated through the performance metric Natural Ventilation Effectiveness (NVE) [56], expressed in Equation (1). It calculates the weighted averaged of hourly ...
