国产活性炭－甲醇吸附式制冷性能研究

STUDY ON THE ADSORPTION REFRIGERATION PERFORMANCES OF DOMESTIC ACTIVATED CARBON-METHANOL PAIRS

建立了一套活性炭－甲醇吸附容量测定试验台，对国产活性炭的吸附性能进行了测试，得到有关吸附方程式Ｄｕｂｉｎｉｎ－Ａｓｔａｋｈｏｖ（Ｄ－Ａ）的关联参数，并对国产活性炭－甲醇吸附式制冷循环进行了模拟计算，讨论了循环ＣＯＰ及单位质量活性炭制冷量Ｑｆ等主要参数。与国际上流行的活性炭ＡＣ－３５相比，国产活性炭材料作为固体吸附式制冷机的吸附剂；具有与ＡＣ－３５相近的ＣＯＰ，但单位质量制冷量Ｑｆ较ＡＣ－３５差些。

n experimental setup for measuring adsorption capacity of activated carbonmethanol pairs is constructed. and the adsorption properties of domestic-made activated carbons. such as Shanghai carbon particles 18# and Jiangxi powder carbon 809. are measured. some important parameters of D-A adsorption equation are thereby determined.Computer simulations are carried out for basic adsorption refrigeration cycle. the COP of a cycle and the refrigerating load Qf of activated carbons are specially studied. the results show that the domestic-activated carbons have COPs close to that of AC-35 activated carbon if they are used as the adsorbent in an adsorption refrigerator. but their refrigerating loads Qf are comparively smaller than that of AC-35.
