Abstract

MIL-101(Cr) and water were applied to adsorption refrigeration technology. MIL-101(Cr) was prepared by hydrothermal synthesis method and characterized by X-ray diffraction patterns (XRD), Fourier transform infrared spectroscopy (FTIR), N adsorption-desorption measurement at 77 K, thermal gravimetric analysis (TGA) and scanning electron microscope (SEM). The adsorption isotherms of water vapor on MIL-101(Cr) were investigated by using a gravimetric water sorption analyzer. This study established the basic adsorption cycle mathematical model and used MATLAB/Simulink for the simulation. The control variable method was used to simulate the effect on the cooling capacity and coefficient of performance (COP) when the desorption temperature changed. When the adsorption temperature was 35 °C, the evaporation temperatures were 15 °C and 20 °C, and the amount of water vapor equilibrium adsorption on MIL-101 (Cr), Cooling power per unit adsorbent mass (SCP), and COP were measured by using the adsorption performance test rig on the basis of a new type of powder adsorbent filling method.

摘要

将MIL-101(Cr)和水应用于吸附制冷技术。采用水热合成法制备了MIL-101(Cr)，并通过X射线衍射图谱（XRD）、傅里叶变换红外光谱（FTIR）、77K下的N吸附-脱附测量、热重分析（TGA）和扫描电子显微镜（SEM）对其进行了表征。利用重量法水吸附分析仪研究了水蒸气在MIL-101(Cr)上的吸附等温线。本研究建立了基本吸附循环数学模型，并使用MATLAB/Simulink进行了模拟。采用控制变量法模拟了解吸温度变化时对制冷量和性能系数（COP）的影响。当吸附温度为35℃、蒸发温度为15℃和20℃时，基于一种新型粉末吸附剂填充方法，利用吸附性能试验台测量了水蒸气在MIL-101(Cr)上的平衡吸附量、单位吸附剂质量制冷量（SCP）和COP。
