Solid adsorption air conditioning apparatus and method
A low-tonnage cooling device - designed to utilize low-grade solar energy or possibly a gas-fired heat source - offers several advantages over larger cooling devices: It uses ambient air for heat transfer, eliminating the need for liquid-cooling components; does not require a secondary refrigerant loop when water is used as a refrigerant; and offers an efficiency as high as or higher than those of available heat-actuated cooling devices. The solid-adsorption process uses water or ammonia refrigerant in a generator-condenser-evaporator-adsorber cycle. The refrigerant is adsorbed on and generated from a solid adsorbent coated onto the interior of a combination adsorber-generator module. The adsorber-generator modules perform each of these functions alternately. The apparatus and process may be used for either cooling or heating functions by a simple adjustment of dampers.
