This video demonstrates a highly efficient, desiccant-based air conditioning system. The speaker explains its design, components, and functionality, comparing its efficiency to traditional compressor-based systems. The primary purpose is to showcase the system's superior coefficient of performance (COP) and explore cost-saving potential.
The video details a desiccant-based air conditioning system. It uses three nearly identical columns filled with bio-balls. Air is pushed in from the bottom, rising counter-current to water or desiccant (a mixture of road salt, calcium chloride, and water) that pours down. This setup acts as an evaporator, dehumidifier, and desiccant refurbisher. A radiator heated by a burner warms the desiccant solution at the bottom of a column. The warm, concentrated desiccant is pumped to an evaporative cooler where a radiator is immersed in a water bath. Fans blow air through this, cooling the desiccant. The cooled desiccant drips back down the dehydration column. The now dry, but warmed air passes through another radiator, cooled by a closed-loop water bath before reaching a final evaporative column. The output is cooled, dry air. The system also incorporates evaporative pre-coolers to further enhance efficiency.
