Start-Up of Air Conditioning Systems After Periods of Shutdown (Humidity Considerations)
Abstract
In many cases the single most important energy
conservation measure that can be taken is to turn
equipment off when it is not needed. In the case
of air conditioning, this generally means turning
it off when occupants leave and turning it back on
in time to have the space comfortable when they
return.
In humid climates special problems are often
encountered when a system is restarted after a
period of shutdown. The temperature and humidity
in the space rises during the period of shutdown.
Unfortunately the latent load required to bring the
space back to comfort conditions is usually much
higher than the sensible load. Most methods of
control are ill suited for this duty. This paper
examines the response of various types of air conditioning
systems during this recovery period and
makes recommendations for system designers.
