Tiny and Simple Device Cuts Air Conditioning Costs  E-mail

windowunitFor those of us who live in places without central air, but with triple digit temperatures, there are few solutions to sumer-time night-sweats that don't include drippy, inefficient window boxes. 

Well, China isn't moving beyond the window unit, but they are making them better.  A Chinese institute has just released a remarkably simple device that takes the condensation from the cold part of the air conditioner and uses it to mist the hot part of the air conditioner.  This simple use of coolant that would otherwise be wasted can increase the efficiency of a window unit by more than 8%. 

From the Shanghai Daily.
"The device is attached to an air-conditioner by a series of tubes," (no...not the internet, an actual series of tubes,) "which collect condensation drops. The water is pumped to the device, which turns it into a fine mist that is sprayed on the back of the air-conditioner, cooling it down significantly. The device is expected to cost about 100 yuan (US$12.50), researchers said."

One can also sleep in the shower, but that can get pretty pruny
That's new?

Hardly a "new" discovery. We had just this set-up in an aircon unit when I was working in Sydney in the late 70's. Made a funny squish-squish sound on the outside as the condensate was splashed up onto the condenser coils!
Only problem is ...
When there is condensation it is usually very humid weather, and so the evaporative (and hence cooling) effect of splashing the water on the coils was lost.
