The 2020 ASHRAE Handbook, “HVAC Systems and Equipment,” discusses various systems and the equipment (components or assemblies) they comprise and describes features and differences.
Editor’s Note: Every successful project starts with a framework. A vision statement. A blueprint.
The editors of Engineered Systems are proud to present The Blueprint — a Q&A interview with HVACR engineering’s leading voices. These one-on-one discussions will examine the trade’s history, current industry trends, and the factors shaping the sector’s future.
The new Fork n’ Pint restaurant in Lake Orion, Michigan, installed front doorway air curtains in an effort to keep patrons and employees comfortable, resulting in more than $500 in annual energy savings and the elimination of $15,000 in potential vestibule construction costs.
Nortek Air Solutions is announcing a 6% price increase effective immediately to all product lines, with a range of 2% to 10% based on material and content type.
A Tennessee district faced an old school HVAC challenge: aging ventilators and space constraints. So this team tried a new-school variation on common VRF retrofits to deliver improved efficiency and critical IAQ: they decentralized the outdoor air, combining enthalpy wheel and VRF components within a single classroom enclosure.
Engineers retrofitting non-air conditioned schools to variable refrigerant flow (VRF) the last few years have relied on centralized packaged DOAS to comply with ASHRAE 62.1 outdoor air standards.
