Solar energy as an inexhaustible supply of clean energy , has been more and more attention worldwide and research . Lithium bromide absorption chiller driven by solar energy and traditional refrigerant compression air conditioning , refrigeration , compared , because of its damaging effects on the ozone layer and does not produce greenhouse gases , faster development. With the popularity of home air conditioning , lithium bromide air conditioning also toward miniaturization . Absorption air conditioning , the how the generator occurrence effect a direct impact on the operation of the system effect . The effect of heat transfer due to restrictions on equipment size and solution flow state , a small generator is not ideal . Variety of reinforced tubes of manufacturing technology becomes more mature , the effect of heat transfer fluorescent tubes are incomparable . So For immersion generator to select a light tube , the T - shaped tube and the surface of the porous tube study , it can be seen by studying the superiority of the porous tube ; Meanwhile, small spray-type porous tube generator heat transfer characteristics and operating conditions , and immersive compared to discuss the pros and cons of both recommended form of immersive porous tube generator for small solar absorption air conditioning generator . For solar single-effect absorption refrigeration cycle , due to the limit of the heat source temperature , the amount of the refrigerant and the refrigerating efficiency of the system are relatively low, so the use of a pressurization cycle to improve the efficiency of the system , i.e. in between the generator and the booster add turbocharger to enhance generator outlet steam pressure . Require cleaning pump chamber , without any other gas or gas impurities , therefore the Roots pumps do turbocharger , a small arc line leaves rotor Roots booster pump , and the pump cavity fluid simulation, obtained under actual working conditions , the pump cavity pressure distribution and velocity distribution , to provide a basis for improved rotor profile .
