There’s
a concept, eh? The author takes a comparative discussion of chiller
technologies and options, and he places it squarely within the current events
context of domestic energy sources, the utility rate landscape, and thermal
efficiency. Read this and then look for Part 2 in the near future.
From sidewalks to hospital entrances and helipads, these systems are becoming a more common part of a project’s mechanical infrastructure. Examine differences between ASHRAE’s old and updated classifications, then review design considerations such as heat of evaporation, heat loss to the atmosphere, and back and edge losses. Tubing, spacing strategies, and controls round out the primer.
Defending against even a simple airborne attack may require a complex
ventilation safety plan - or at the least, a well thought-out
strategy. Sensor capabilities, sensor placement, response speed, and
the general ventilation system are some of the factors that play into
protecting occupants (and even property) in the case of something
worse than an accident.
