Abstract:
A new type of solar energy storage/evaporator/collector is presented. Mathematic model about phase change heat transfer of the storage/evaporator/collector is established. The change laws of temperature field and liquefaction ratioof solar energy storage/evaporator/collector filled with paraffin wax or decanoic acid are achieved. Experimental comparative study of temperature in thesolar energy storage/evaporator/collector is done whenusing water,decanoic acidor paraffin waxas PCM sunder the typical operating conditions in spring in Nanjing. The result shows that the solar energy storedduring the day can beused at night when PCMs asdecanoic acidor paraffin wax has been filled in. And comparative study of instantaneous collection efficiency of thesolar energy storage/evaporator/collector is done when using water,decanoic acidor paraffin wax. The change laws that variates with solar radiation is achieved. The formula of collection efficiency with three different medium have been fitted. The results indicate that the solar energy storage/evaporator/collector filled with paraffin wax has the highest instantaneous collection efficiency.
