Solar Thermal Hybrid Air Conditioning System (Solar Thermal Magazine) – This video is of a test installation in Hawaii of a solar thermal collector being used to heat the refrigerant of a commercial air conditioner before it goes into the second stage of the compressor cycle. The concept is to use this to reduce the second stage compressor current to the same as the first stage saving energy from using the sun to expand the refrigerant.
In this design the warmer the day the more money you save. The beauty of this solar thermal hybrid system is that it can easily be a retrofit to your existing home or office air conditioner.
Very cool use of solar thermal technology to reduce energy today.
