Experimental Investigation on Working Pairs for a Two-stage Sorption Refrigeration Cycle
Recently, a CaCl2-BaCl2-NH3 chemisorption freezing cycle driven by a low-temperature heat source has drawn an increasing amount of attention. To develop a working pair with a more desirable performance than CaCl2-BaCl2-NH3, working pairs of CaCl2-NaBr-NH3, SrCl2-BaCl2-NH3, and SrCl2-NH4Cl-NH3 were i...

| description | Recently, a CaCl2-BaCl2-NH3 chemisorption freezing cycle driven by a low-temperature heat source has drawn an increasing amount of attention. To develop a working pair with a more desirable performance than CaCl2-BaCl2-NH3, working pairs of CaCl2-NaBr-NH3, SrCl2-BaCl2-NH3, and SrCl2-NH4Cl-NH3 were investigated and compared. Most composite adsorbents were developed with a novel matrix of expanded natural graphite treated with sulfuric acid (ENG-TSA), leaving one serial with expanded natural graphite (ENG) for comparison. For SrCl2-NH4Cl-NH3 and CaCl2-NaBr-NH3, experimental results show that the maximum adsorption quantities are 95.4% and 88.6% of the theoretical values, respectively. Simulation results indicate that the best results are obtained from CaCl2-NaBr-NH3, and its specific cooling power (SCP) and coefficient of performance (COP) are as high as 260.74 W/kg and 0.285, respectively, which are 15.1% and 5.6% better than the values for CaCl2-BaCl2-NH3. It is also noted that, for different working pairs, the COP, cooling capacity, and SCP range from 0.215 to 0.285, 2 to 3.65 kW, and 161.4 to 260.74 W/kg, respectively. Comparisons also show that the ENG-TSA matrix effectively improves the SCP. For example, the SCP of CaCl2-BaCl2-NH3 is improved by 40.2%, when compared with a working pair with the ENG matrix. |
