Structure Design Of Adsorption Bed Using Sintering Heat Pipe And Experimental Study

Due to the increasingly reduced energy resources, energy saving and utilization push the development of the adsorption refrigeration research. Adsorption refrigeration systems are more suitable for ships compared to absorption refrigeration, because it does not need an absorption pump. The heat and mass transfer in adsorption bed systems are the main factors influencing the performance of adsorption refrigeration systems. Combining adsorption refrigeration with the highly efficient heat transfer characteristics of heat pipe technology will improve the performance of the adsorption bed. The heat pipes must be able to alternately heat and cool the adsorption bed, therefore the selected heat pipe should work transfer heat well in two directions.The main works are summarized as follows:1. Analysis of the working condition and heat transfer mechanisms. From this, a sintered heat pipe with copper power was selected as the device transferring heat in the adsorption refrigeration system. The sintered heat pipe has an excellent two-direction heat transfer characteristics which meet the needs of adsorption refrigeration system.2. A single pipe testing system was designed and built to determine the wall temperatures and resistances versus angle with heating at the bottom as well as on the top. Through the comparative and calculated analysis the performance of the heat pipe was determined.3. Using the heat pipe performance test, the dimensions of the adsorption bed were calculated and the sintering adsorption bed using silica-gel as refrigeration working pair was designed.4. The ideal refrigerant circulation was calculated and the condenser and reservoir was design to match the adsorption bed. A liquid meter was fitted to the reservoir to determine the adsorption refrigeration performance. Then,set up the sintering heat pipe adsorption refrigeration system.
