In the
last post we described a possible configuration for an evaporative precooler to lower total air conditioning operating costs at the expense of some additional capital costs (ducts, heat exchanger, evaporator) and perhaps a little additional maintenance costs on those items. Of course, in order to make a decision on the payoff time, you have to know your climate conditions, your equipment costs, your operating costs, and the potential savings from the addition of the evaporative cooler. In this post, we’ll provide a fuller description of the potential benefit you might be able to expect from an evaporative cooler for given inlet conditions.
