Numerical simulation and optimization of solar heat storage unit regenerative process

  • Received Date: 2015-11-30
  • Based on the uniform design method, six solar heat storage devices were disigned, the phase change material of paraffin RT110 was encapsulated in the heat storage unit of cylindrical tube with inner finned, and the heat storage unit model was established and its heat storage properties were investigated. Results showed that the structure and size of the heat storage unit had a great influence on heat storage rate of phase change materials. The smaller the inner diameter, the more the fins and the longer the fin width, the capacity of heat storage was greater. The capacity of heat storage was influenced greatly by the second-order interaction of various factors. The fin width, the fin number and the inside diameter of cylindricity collaboratively affected the capacity of heat storage unit.
