ELECTROLUX REFRIGERATION USING SOLAR HEAT

 

ABSTRACT

The project consists of an Electrolux refrigeration system using solar energy as input. This system was actually invented by two Swedish engineers, Von Platen and Carl Munters. The idea was first developed by the ‘Electrolux Company, of Luton, England, hence the name ‘Electrolux refrigeration system’. The principle behind Electrolux refrigeration is that it uses three gases to accomplish its cooling effect namely ammonia (refrigerant) water (absorbent) and hydrogen. Ammonia is used as the refrigerant as it is easily available, environmentally friendly and can produce a better cooling effect. Hydrogen is used to reduce the partial pressure of ammonia vapour in the evaporator chamber so that more ammonia evaporates yielding more cooling effect. Heat input is required at the generator where aqua ammonia is heated to get ammonia vapors. In this project, an experimental setup for Electrolux refrigeration is made using solar energy to supply input heat. A double involute cusp shaped plate is used as the solar collector. Two 1” diameter pipes welded together is placed at the focal point of the involute cusp which acts as the generator pipes. Solar energy is concentrated to these pipes by the solar collector, heating the aqua ammonia solution. The rest of the system is unaltered.......MORE CONTACT
