通过对不同操作条件下制冷剂的解吸和吸附质量的比较，对三种化学吸附工作对在再吸收循环下的性能进行了系统的研究。在主反应器中均使用nh3和mncl2作为制冷剂，但在二次反应器中使用不同的盐来产生冷却效果。这些盐是NH4Cl或NaBr或BaCl2。实验结果表明，在0℃及以下的冷却条件下，nh3与bac2的反应转化率低于25%，而与其他盐的反应转化率至少为80%。在主堆热源温度为155℃，双堆散热器温度为30℃，冷却效果产生温度为0℃的条件下，使用NH4Cl的系统与使用NaBr的系统的性能系数（COP）相近，均在0.30左右；而前者的比冷却功率（SCP）比后者高5%。由于系统中与NH4Cl的反应实际上停止的时间比实验中所用的时间短得多，因此可以预期，如果缩短冷却时间，两个系统之间的SCP差异将会大得多。
The performances of three chemisorption working pairs operating under the resorption cycle were studied gravimetrically by comparing the desorbed and adsorbed mass of refrigerant in different operation conditions. All pairs used NH3as refrigerant and MnCl2in the main reactor, but each one used a different salt for the cooling effect production in the secondary reactor. These salts were NH4Cl or NaBr or BaCl2.The experimental results indicated that the degree of conversion in reaction between the NH3and BaCl2was inferior to 25% during cooling production at 0 °C or below, whereas the reactions with the other salts had conversions of at least 80%. When the systems operated with heat source temperature for the main reactor at 155 °C, heat sink temperature for both reactors at 30 °C, and cooling effect production temperature at 0 °C the coefficient of performance (COP) of the system using NH4Cl and the system using NaBr were similar and around 0.30; however, the former system had a specific cooling power (SCP) 5% higher than that of the latter system. Because the reaction in the system with NH4Cl was practically halted in a period much shorter than that used in the experiments, it is possible to expect that if the period of the cooling period was shortened, the difference between the SCP of those systems would be much higher.
