There’s no doubt about it – air conditioning has improved the lives of millions, and our society as we know it would change a lot without air conditioning. We breathe a sigh of relief coming into a cool building, away from the hot air outside. Our houses are air conditioned, as are our workspaces and public areas, but are all these areas air conditioned in the same way? Why does air conditioning get so much more complicated as we scale up?
The first (and most obvious) reason is that large commercial areas take up more space than your average home. This means your HVAC (Heating, Ventilating and Air Conditioning) unit must be more powerful to deal with larger volumes of hot air. The other, less obvious consequence of a larger commercial space is more bodies within that space. More people means more body heat being generated, which means the unit has to work even harder.
The consequence of a more powerful unit is that it is louder and noisier than a residential system. This presents interesting challenges for a business – how can it place the unit in a way that doesn’t impede traffic, create distracting noise or become prone to vandalism? The answer is right above you – on the roof! This means most commercial HVAC units are specially designed to cool buildings from the top-down, which created some interesting engineering challenges.
We hope our homes will be large enough to accommodate us for a long time; moving is a hassle, and it’s nice to grow into a space. Conversely, we hope our businesses expand beyond our wildest dreams and that we can’t fill the space we bought initially! Commercial HVAC units are designed in a modular fashion with these fluctuations in mind; should the needs of a business change, modules can be added and removed. Residential systems are fixed, and expansions may mean a new system.
Residences can afford to have less complex mechanisms, even if it takes up more space; most residential systems are split between an outdoor compressor and an indoor evaporator. This makes the systems easier to repair than commercial systems, which are almost exclusively single unit. Commercial systems are also more likely to have multiple thermometers, and to be able to selectively cool areas of a building; all in all, they’re much more complex!
All in all, while commercial air conditioning is much more complicated than residential, it’s important to always trust the professionals, either way! Sophistication aside, a badly installed residential unit can cause uncomfortable temperatures and humidity in your home, not to mention the increased electricity cost!
