Cold night closer

Auto window closer based on temperature drop
  [vote for,

Every year around this time I get a cold. It is always for the same reason, it is hot day followed by a hot night, so I leave the window open to cool off the bedroom and fall asleep, sometimes above the covers. During one of these nights the temperature drops 20 degrees and I wake up with a sore throat. The cold soon follows.

I should know better as this situation almost killed me one night at college, Syracuse is known for it's massive temperature changes. That night I was in a water bed and the temperature dropped 60 degrees F. or 20+ degrees C and the heater died trying to keep up.

In any case a simple pneumatic door closer type piston compressed to a catch by the opening of the window. The catch would be moved by a bi-metallic spring or simple electronic thermometer trigger.

Closest patent I could find [MisterQED, Apr 28 2009]

You will probably have to cannibalize one of these. http://www.simplyco...opening/default.asp

Lee Valley Heat-Activated Window Opener http://www.leevalle...cat=2,43224&p=10543
Intended for opening greenhouse windows when it gets too warm inside, but might be usable for house windows too, somehow. [notexactly, May 01 2019]


       Note that the invention is by Trevor Bayliss.

       So you opened the window and in flew Enza?
Louvres that are controlled either Thermostatically or through Rain or Humidity are widely known to exist. Most common in greenhouses (commercial ones that is) and also for glass atria in commercial buildings.
Funny thing is, I got called to site because *my* louvers were letting the pigeons in - Tell me again why that is a Controls Problem.

       Inaduquate screening?   

       According to Wikipedia, Syracuse enjoys a typical Mediterranean climate, with mild, wet winters and warm to hot, dry summers. Nothing to suggest climate extremes.

       I thought, ""QED", that's Latin, right?", so, he's probably Italian, or possibly even Greek (Archimedes lived in Syracuse), so why on Earth would I imagine that there would be a Syracuse other than in, well, Syracuse?
OTOH, the use of obscure units of temperature did concern me somewhat.

       make it a whole house solution with a central thermostat. Not sure why that has not been done...   

       The windows are constantly adjusting to keep a constant temperature and/or airflow. When it gets too hot to keep cool with windows, all the windows close and the ac is activated.

       Central has the ask for a global temperature, each window has fine local self control, depending on the mechanisms situation.
