HVAC stands for Heating, Ventilation and Air conditioning is the technology of automotive and inside environmental comfort. HVAC system design is based on thermodynamics, heat transfer and fluid mechanics. A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other to reduce the water's temperature. It operates on the principle of removing heat from water by evaporating a small portion of water that is recalculated through the unit. The mixing of warm water and cooler air releases latent heat of vaporization, causing the water to cool. Cooling tower piping systems have evolved over the years from simplistic, dedicated hydraulic loops that lacked complexity to large-volume, multiplexed systems that offer peak operational efficiencies. The evolution of a more sophisticated system is due in part to the advent of advanced controls and the operational flexibility of modern chillers, cooling towers. Cooling tower piping systems are designed to be streamlined to keep capital costs low while yielding the most energy-efficient solution. The effects on the performances of cooling tower are determined by following parameters: (1) flow rate of water (2) diameter of pipe
