(Newswire.net — May 26, 2020) — In the present day, the cooling of homes is usually important to maintain tolerable internal comfort. This can be realized by active and passive solutions. The research focused on passive solutions shows that evaporative cooling towers are an essential element of plus energy houses in Southern Europe. Improvements to the design of the existing ventilation tower of a Solar Decathlon House made by the Hochschule fur Technik Stuttgart are proposed and tested in eight locations in countries like Greece, Italy, Spain, and Portugal utilizing dynamic thermal and computational fluid dynamics simulations to predict energy consumption, mean and peak carbon dioxide levels, ventilation rates, fresh air distribution, cooling potential, indoor air quality as well as water consumption of the evaporative cooling system done within the tower. Results indicate that a 50% decline of the yearly energy demand for space cooling to be satisfied by other systems is realized without encroaching on the internal comfort.

What is a cooling tower?
A cooling tower is termed as a heat exchanger that comprises of water and is utilized in removing excessive heat by some buildings as part of their air conditioning, ventilation, as well as heating systems. Cooling towers cool water by placing air and water in to direct contact to extract waste heat into the atmosphere.
If the water and air join, a limited amount of water is evaporated to create a cooling action. The cooled water is afterward pumped back to the condenser to suck up the heat. An evaporative condenser is termed as a device that accommodates the condensation or return to a liquid form, of a hot gas or vapor in a tube system utilizing the water of evaporation flowing over the tubes.
In other words, an evaporative condenser utilizes a system of tubes exposed to a continuous flow of water to cool alongside condensing a hot gas.
Can a polluted cooling tower be maintained?
Yes, it can be maintained. A polluted cooling tower contributes to a slow cooling capacity that negatively impacts the reliability of the system and could result in to health risks. But, this can be avoided by conducted regular preventive maintenance.
What is fill in a cooling tower?
Fill is termed as a medium utilized in cooling towers to increase the surface area available for the water. In a cooling tower, the important part is the cooling tower fill. Fill is a plastic sheet utilized in cooling towers to make the more surface region of the cooling tower. If you want an extended surface, make more contact between water and fills to let water occupy a bigger surface area in the cooling tower fill. Cooling tower fills make hot water occupy a big surface area so that it cools quickly.
On cooling, the water is poured in a water container from which it is again pumped to cool the hot water and let warm air leave the fill releasing it from above the cooling towers continuously.
Why do you need ventilation cooling towers?
- Cooling towers are needed to eliminate heat by extracting waste heat given off as a by-product in industries in to the environment by cooling hot water further. Cooling towers give you a cost-effective and energy-saving operation of systems that need to be cooled. Several industrial facilities utilize large quantities of water to cool their manufacturing plants.
- Another significant consumer of cooling towers is the large commercial HVAC systems for solace cooling. HVAC structures are used usually in extensive office buildings, hospitals, and schools among other plus energy houses that produce more energy than they use. Industrial purposes cooling towers can be bigger than HVAC systems and are utilized to get rid of heat that is absorbed in the circulating cooling water structures utilized in power stations, petrochemical plants, and other industrial establishments.
- With the high rates of pollution around the world that are arising from the need to manufacturer more products to satisfy the needs of many people, the machines and processes of industrial plants generate high amounts of heat and must be cooled to let those machines operate efficiently and effectively. The most efficient, cheaper and time-saving solution is by installing a cooling tower.
Conclusion
Cooling towers are good for plus energy houses as they minimize high temperatures that may be bad for business or productivity by creating cooler environments.
