ABSTRACT: The severity of the ozone layer destruction problem has called for rapid developments in environmentally friendly air conditioning technologies. Ongoing deregulatory efforts in the Organization for Economic Co-operation and Development (OECD) nations will ease the penetration of thermally activated heat pump systems. Absorption (liquid-vapor) and adsorption (solid-vapor) heat pump systems are thermally driven and have the advantage of being environmentally benign: both their ODP (Ozone Depletion Potential) and their GWP (Global Warming Potential) are zero. Adsorption cycles using silica gel-water as the adsorbent-refrigerant pairs have a distinct advantage over other systems in their ability to be driven by the heat of relatively low, near-ambient temperatures so that waste heat below 100°C can be recovered. The multi-bed multi-stage silica gel-water-based adsorption systems can be powered by low-temperature waste heat below 100°C, even as low as 50°C if the multi-stage regenerative scheme is adopted.
