Famous mathematician Edward Lorenz coined the phrase “The Butterfly Effect,” which is the belief that some small occurrence could create devastating results in another location far away.
Warm discharge plumes sweeping back into air-cooled condensers is nobody’s idea of an ideal performance environment. This CFD study shows how wind speed, wind direction, spacing between chillers, and separation from adjacent buildings all factor into the conversation about the best defense against unwanted hot air.
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.
Now that many of us are back from the annual ASHRAE and AHR Expo conference, our minds may be jangling from having seen an array of innovative technologies utilizing the cloud, smartphones, and demand automation.
