It’s important to pull in more oxygen from outside in huge stores with HVAC
Although some building supplies are used across all applications, there are some fairly important differences to spaces meant for residing versus those meant for commerce.
- It’s pretty easy to imagine that a business intended to sell shelves worth of items to a small assortment of shoppers each day is going to have more electricity demands than a small residence that houses a single person.
Getting an area wired the right way so it is safe to use commercially can vary in cost widely depending on how immense the business is going to be. The plumbing might need to be a little more expansive if it’s going to be a diner with a dish room and a good amount of lavatories. But these differences go even further than that. One small fact that few people realize is that most commercial heating and cooling machines draw in certain amounts of outdoor air into the indoor temperature control system. This might seem somewhat puzzling to some, however there’s a simple explanation for why this is actually done. With the larger a business gets with its foot traffic each and everyday, more and more of the oxygen indoors is being depleted by the shoppers breathing it into their lungs. As they exhale, this oxygen is converted into carbon dioxide. If you’re a store as gigantic as Walmart, this effect happens at an overwhelming rate. If these commercial Heating and Air Conditioning machines didn’t pull in oxygen from outside, all of the shoppers would be breathing carbon dioxide after enough oxygen is lowered in the air. Although this is still technically how it works with any indoor temperature control system, it’s not a big issue so much with residences where the foot traffic is low and the air flow is high by comparison.
