HVAC How It Works And Why A Factory Requires It

Commercial Ventilation
Commercial ventilation has become crucial to the maintenance of buildings across the globe. Employing systems that regulate heating, ventilation, and air conditioning (or, in short, HVAC), commercial ventilation is used in nonresidential buildings and uses a form of air exchange to moderate enclosed environments.

It comes in a few different forms and methods: natural ventilation, which uses air pressure outside to alter the inside; mechanical ventilation, employing both positive and negative pressure; and mixed mode ventilation. Each of these methods has its own pros and cons, but they all contribute to the single system of commercial ventilation.

A form of natural ventilation that has gained popularity is the evaporative cooler. This system works by intaking hot, dry air and forcing it onto a wet cloth. When this is done, the heat is removed from the air and creates cold moisture, which can then be used to circulate a building. Evaporative cooling began as mainly a form of ventilation used in only hot and dry areas; however, when scientists created two types of evaporative cooling (direct evaporative cooling evaporates water to produce moisture, and indirect evaporative cooling removes heat without forming moisture), this form of cooling became more universal, and is now able to be used across any climate.

Factory heating is a form of heating in which the ventilation is produced from a single room, often known as a boiler or generator room. Opposed to evaporative coolers, boilers produce heated water or hot, evaporated moisture, and this circulates a building through a network of radiators and other heaters. If a large, nonresidential space needs to be cooled, factory cooling (or water cooling) can also be used.

The difference between evaporative cooling and factory cooling is that, in factory cooling, the water is already present, and the machinery has no need to draw on outside air. High-production factories may feel the need to use cooling towers, large, funnel-like structures that remove heat and eject it into the atmosphere, keeping only the cool air within the building.

Both residential and nonresidential buildings use commercial ventilation; it has almost become a necessity in our society, used in many homes, schools, office, and factories. The different modes, forms, and methods of commercial ventilation demonstrate the variety of needs desired by society and certain buildings, but technological advancement has allowed us to adjust and create better systems that work in all situations and locations.
