Why APR Control?
Air conditioning applications suffer from systemic problems, such as dehumidification, that are not easily solved with current equipment and controls capabilities. Even modern air conditioning systems are unable to vary system capacity to match changing load conditions other than with expensive technologies.
Proper system selection (matching capacity to load) is difficult even in the best circumstances because load rarely remains constant. Operational conditions change seasonally, monthly, daily, and even hourly. Changes in occupancy, solar gain, and ventilation air, to name just a few, are inevitable. Every contractor and engineer has experienced systems that short cycle or cannot maintain dehumidification and comfort because they are oversized.
