Our church building is legitimately a converted manufacturing building with a flat roof, originally, only the business’s offices were air conditioned, and so when my buddy and I bought the building, one of the first things that needed to be done was install central air conditioner, then a committee researched the occasions by contacting local Heating & A/C businesss, and there was the conventional type of central air conditioner, in which an exterior component is connected to a forced air boiler.
The boiler would hold an evaporative heat exchanger & fan, while the the outside unit would cabin the compressor, compressor fan & a second heat exchanger! Comparatively, rooftop cooling systems contain the entire system on the roof.
Aside from bypassing the boiler, rooftop cooling systems limit the amount of work that the unit needs to do, lowering energy cost. Also, since a rooftop cooling system is contained in one unit, any future problems would be straight-forward to address by an Heating & A/C serviceman; Rooftop cooling systems are popular with commercial buildings, as they are more efficient in cooling immense spaces. Our sanctuary holds four hundred people, so this factor is important. Once the information had been gathered, my buddy and I looked at the cost of installing either of the two systems. The traditional air conditioner option wasn’t as costly to install, however the long-term costs would add up to be more than the rooftop cooling system. The main reason that rooftop a/cs are more extravagant to install is that they have to be hauled up to the roof, requiring multiple certified Heating & A/C servicemans. The additional servicemans would be needed for an entire day in order to complete the initial set-up, then my superb friend and I did end up going with option two, & over the years my buddy and I have loved reliable, cooled air during our church services.
