R14 -- Forced-Circulation Air Coolers - (SI)


ASHRAE / 2010 / 6 pages ISBN: 9781933742823

Forced-circulation unit coolers and product coolers are designed to operate continuously in refrigerated enclosures; a cooling coil and motor-driven fan are their basic components, and provide cooling or freezing temperatures and proper airflow to the room. Coil defrost equipment is added for low-temperature operations when coil frosting might impede performance.
Any unit (e.g., blower coil, unit cooler, product cooler, cold dif-fuser unit, air-conditioning air handler) is considered a forced-air cooler when operated under refrigeration conditions. Many design and construction choices are available, including (1) various coil types and fin spacing; (2) electric, gas, air, water, or hot-brine de-frosting; (3) discharge air velocity and direction; (4) centrifugal or propeller fans, either belt- or direct-driven; (5) ducted or nonducted; and/or (6) freestanding or ceiling-suspended, or penthouse (roof-mounted).Chapter Table of ContentsTypes of Forced-Circulation Air Coolers
