Using Heat to Cool Buildings

Novel materials could make practical air conditioners and refrigerators that use little or no electricity.

It could soon be more practical to cool buildings using solar water heaters and waste heat from generators. That’s because of new porous materials developed by researchers from the Pacific Northwest National Laboratory. These materials can improve a process called adsorption chilling, which can be used for refrigeration and air conditioning.
