Propane powered refs
For those who doubt the workings of solar aircon, we see propane powered refs or freezer as published in Scientific American.
In the fishing village of Maruata off Pacific Coast of Mexico, they have been producing ice without electricity: only sunlight powering solar ice makers producing l/2 ton of ice everyday. How is this possible? Options: using solar panels, or that which uses absorptive chillers using ammonia or lithium bromide.
The principle used, without using electric compressor is turning on the heat which raises temperature and pressure, turning off heat lowers pressure which causes liquid turn into gas again creating cooling effect.
