Finding Engineering Inspiration
To design an HVAC&R system, engineers must be able to
see beyond what is and seek out what could be. It's why
we talk about the arts and sciences of engineering. And,
like any artist, an engineer needs inspiration.
That's why the cover story is about designing environmental controls for applications in space. To deal with
terrestrial challenges, it can be inspiring to think about the extraterrestrial. The environment of deep space is a near vacuum, with temperature
extremes ranging from approximately −200°F to 200°F (approximately
−129°C to 93°C). In addition, space objects traveling at high velocities relative to travel vessels in deep space may potentially damage thermal management machinery and accompanying accessories exposed to space.
On Page 12, John Constantinide, P.E., Member ASHRAE, and
Hamidreza Najafi, Ph.D., Associate Member ASHRAE, explore environmental controls in space, using the International Space Station as a
working example of how to deal with the extremes of that environment.
But the challenges on Earth are also particularly difficult right now. For
example, what do you do when you must create many negative pressure
hospital patient rooms in response to a pandemic and you don't have
much time? Frank Shadpour, P.E., Fellow ASHRAE, and Stefanie Johnson
discuss their recent experiences in answering that question starting on
Page 24.
How do you predict virus propagation through central air-handling systems and how do you evaluate the virus containment efficiency of the systems? Renat Manassypov, Ph.D., P.Eng., Member ASHRAE, recommends
simple engineered measures that can improve the system's virus containment efficiency during virus infection outbreaks, starting on Page 17.
Although ASHRAE Journal articles are peer reviewed, they don't necessarily provide official ASHRAE guidance. ASHRAE's Epidemic Task
Force is leading that effort, and chair William Bahnfleth, Ph.D., P.E.,
Presidential Member/Fellow ASHRAE, discusses common misunderstandings, easy operating strategies and most frequently asked questions
about the COVID-19 pandemic starting on Page 6.
As I said in June, this is your ASHRAE Journal and there are many ways
to participate. Each article and column includes a link to a survey where
you can share your thoughts. Letters to the editor can be sent to me at
sfoster@ashrae.org. And, you can submit papers at https://ashraejournal.
submittable.com/submit. In addition, we are working on a how to write
for ASHRAE Journal webinar we are hoping to launch in the fall. Email me if
you have a particular topic you'd like to see discussed in the webinar.
