Over the years I have noticed that there is some confusion as to what each are, what they do and when you need them. This article is written to clear things up. To start, the vapor/compression cycle of typical air conditioning is this: Heat transfers from the space to the evaporator coil and refrigerant in [...]

Engineered Air Solutions takes pride in our knowledge and product offering for humidity control. While we have dehumidifiers, this article is about adding humidity. Here are the basics: Canister type: Probes in a plastic tube will arc and boil water at the probe. Pros: Low first cost, easy maintenance, modulating output, compact footprint Cons: Higher [...]
As using refrigeration to cool spaces (or heat in the case of a heat pump), the better one understands some of the components, the better we can apply the right piece of equipment for the right application for trouble free operation. Heat-Pump: Unlike a heating coil, burner, etc, a heat pump is an air [...]
Over the years all of us in the industry have had the issue where a space has a humidity problem and as an engineer, mechanical contractor, building owner or equipment vendor has been asked what can be done. If the HVAC unit is old, many will simply replace the old unit with a new unit [...]
