Evaporative Cooling System Design | Passive Low Vitality Systems
Updated on April 6, 2013 akihan moreContact Writer An summary of evaporative cooling systems
Evaporative cooling systems makes use of evaporation as a cooling method in cooling the surrounding air by adding moisture within the air hence increasing humidity. It is a low energy passive system. The following sections are categorized into sections stating the required situations, implementation considerations and other issues. Case studies are listed as reference to discuss on how these systems are implemented and the implication they’ve on structure design.
Climate: Evaporative cooling systems are suitable in any dry local weather, particularly cool and dry climates. For instance, it can be used in excessive altitude areas. A dry atmosphere is needed for evaporative cooling because of higher evaporation charges. The evaporation process would absorb heat and create coolness in the encircling.
Areas with cooler temperatures are additionally most well-liked, as the gap between the environmental ambient temperature and human comfort range is smaller as in comparison with a scorching and dry atmosphere. This might translate into energy saved attributable to a decrease cooling load.
Utility: Evaporative cooling programs are suitable for residential, industrial and business buildings; especially in areas with big open spaces that encourages air circulation. Integration of evaporative cooling systems with other lively methods are dependent on site conditions. Filters to purify polluted air, humidifiers to maintain the humidity or different lively systems may be installed in tandem with evaporative cooling.
Implications of implementing evaporative cooling strategy Architectural design: Architectural aesthetics could also be affected upon the introduction of the passive downdraft evaporative cooling towers as a result of uncovered shafts. The introduction of underground evaporative cooling shafts would also have an effect on the spatial planning of underground spaces. In addition, the availability of water our bodies has to be taken into consideration with the general constructing design.
Value: Initial building price is mostly greater, as there is a need to construct addition structure and the tools needed is usually extra costly as compared to the standard cooling methods. However, the advantages are that it reduces operational price considerably.

Human comfort: There’s a necessity for an integration of passive and active design to ensure human thermal consolation ranges are met. Evaporative cooling is a passive course of where it acts as a pre- conditioner to cool the air earlier than utilizing mechanical means to keep up humidity level.
Power consumption: The programs has larger embodied power due to the construction of infrastructure, however typically power consumption can be greatly reduced in the range of 25% – 70%, relying on the individual evaporative cooling system setup.
Integration:The vitality consumption of the system will be additional lowered with the assistance of other programs. For instance, evaporative cooling systems may be integrated with photo voltaic chimneys to reinforce air-circulation or incorporate renewable power provide to additional cut back energy consumption.
Case research: Torrent Research Centre, Ahmedabad, India
A passive downdraft evaporative cooling (PDEC) system is selected. Vertical shafts acts as a cooling tower with smaller exhaust shafts. These are positioned at strategic areas.

Fashionable interpretations of this are used in Queensland buildings. Its referred to as a ventilation stack. Inner home windows or lourvres would open into a void or stack which would have a number of whirlybirds above the stack which can suck heat from the inner living
