Evaporative cooling tower architecture.

The malqaf is a tower used to catch the air situated in a high position on top of the buildings with a crown of column around facing the dominant winds. A building looking to achieve credits for optimizing energy performance can get about halfway to certification by implementing hvac. Cooling is provided whilst keeping the evaporative process outside which avoids elevating the indoor humidity level. Principles of evaporative cooling system a.

The air is cooled. They are the most economical approach to cool large amounts of water. When warm dry unsaturated air is pulled through a water soaked pad water is evaporated and is absorbed as water vapor into the air. Due to this fact the fountain is used in both the traditional and the contemporary islamic architecture as a passive cooling system or part of a complex passive cooling system such as in the middle of a courtyard house in the exit air from a wind tower or located in an air stream passage inside a living room as shown in fig.

Astula 4240 architecture. Evaporative cooling is achieved by an adiabatic process in which the sensible air temperature is reduced and compensated by latent heat gain. The use of fountains and vegetation in the courtyards or the act of pouring water on the floor or the use of large porous clay pots filled with water. During the day the walls serve to keep the temperature lower in presence of wind this process is.

During the night the tower walls absorb heat from the air contained in the tower and the denser cooled air goes down inside the building. Evaporative cooling towers global ecology center carnegie institution for science ehdd 260 panama street stanford california united states credit. An evaporative cooling tower provides cooling based on a design wet bulb temperature. Evaporative cooling towers typically cool water to approximately 85 f but may cool as low as 65 f.

An evaporative cooling tower system capable of achieving these goals has the potential to earn points toward energy optimization credit including up to 20 in existing buildings and up to 18 in new buildings.
