Eco-friendly evaporative coolers are capable of cooling large areas, but this kind of potent cooling action does require extra muscle. In order to accomplish this level of coverage, larger mechanical components are built to partner with energy efficient electrics. System equilibrium is sustained inside the beefy appliance, but will this strong breeze still maintain its coverage when the thermometer mercury rises?

Anchoring Performance Ratings

There’s only a handful of operating parts within the cooler, which is why the mechanism maintains its near non-existent carbon footprint. Obviously, since there’re no supplementary parts at work, those few parts must work tirelessly despite the ambient heat. Product ratings take care of this requirement. The CFM rating (Cubic Fet per Minute) provides an unambiguous and quantifiable measurement of airflow. Typically, the power of the inbuilt electrical fan and the physical size of the fan blades determine this value, but the water flow rate should also scale to provide more moisture for the pads when the evaporative effect increases.

Battling Thermal Dynamics

There are scores of indecipherable laws of thermal dynamics, most of which we can ignore. Enthalpy is one variable that can’t be ignored. As discussed in previous articles, this term describes the volume of heat that’s already saturating the local atmosphere. Enthalpy occupies internal spaces and external climates, but a robust evaporative cooler can overcome the thermal build-up over time. Basically, the laws of thermal dynamics will submit to the appliance’s potent fan, but the process will take time. Maintain cooling momentum by keeping the unit functioning at peak efficiency, by removing obstructions around the fan, and by maintaining the unit. In conscientiously carrying out these actions, the hot climate will cool and assume a refreshing ambiance over a predictable period of time.

Scaling the Thermal Envelope

At this point, we’ve mapped space and measured volume so that a localized area matches the CFM rating of our eco-efficient cooler. The unit is maintained properly, and the internal parts are sized to ensure large masses of air are shifted through a predefined channel. Next, the cooling media requires lots of moisture here, so the tubes are typically sized with a broader diameter than conventional evaporative devices. Similarly, the spray nozzles require a beefy upgrade.

Old style reasoning works well in this situation, with the spray nozzles, fan blades, and tubes receiving the resizing treatment. Modern technology also has its say, as the larger parts mesh with highly efficient electrical pumps and fan motors to really curb energy output.
