The Simulation Analysis Of An Adsorption Solar Cooling System With Evacuated Tubes

Adsorption system can utilize solar energy and industrial remaining heateffectively. At same time, it has unique advantage of using natural refrigerant instead ofCFCS. For these prominent advantages, adsorption refrigeration technology arouses awide concern in recent years. But, solar adsorption refrigeration is not in the practicalengineering application, the main reason is that the refrigeration efficiency and systemreliability is low.Firstly, the solar radiation intensity of a typical summer day in wuhan is calculatedby HottelModel mathematical model. Then, compare the result with the experimentaldata to validated its credibility, and use it to predict the intensity of solar irradiance inwuhan for one year. On consider of existing adsorption working medium, heat transferperformance of the strengthening technology and continuous circular manner, a newpipe-type solar adsorption refrigeration system was designed using activated carbon-methanol,which was based on Solar cooling tube’ technology and aim at small civilbuilding air conditioning/refrigeration. The system was matched by a small cold storageas an example.The mathematical model of the multiple tube type solar adsorptionrefrigeration simulation system was established on simulink platform using thelumped parameter method. Based on the real-time working condition of a typicalsummer day, refrigeration and air conditioning working condition were systematicallyanalyzed, including the cycle time, returning the thermal mass, desorption hot watertemperature and cooling water temperature effect on the properties of pipe typeadsorption refrigeration system, its operating characteristic is analyzed and optimized.
