对以CaCl2 为吸附剂、NH3 为制冷剂所组成的化学吸附式制冷工质对的吸附性能进行了研究 ,得到了吸附等温线并回归出吸附等温方程。研究结果表明 ,CaCl2 —NH3工质对的吸附制冷量大 ,适宜太阳能或低品位余热驱动 ,是性能优良的工质对。
Adsorption performance of chemical adsorption refrigeration working pair consisting of CaCl2 as adsorbent and NH3 as refrigerant was studied. The adsorption isotherm was obtained and the adsorption isotherm equation was obtained. The results show that the CaCl2 -NH3 working medium has a large adsorption refrigeration capacity and is suitable for working with solar or low-grade residual heat.
