This work comes as a part of a series of researches carried out by our team to study and present new materials with distinctive properties suitable for adsorption applications. As we previously studied employment of many Freons within the adsorption cooling systems, this paper expresses a study using HFC404A with activated carbon (Maxorb III). Adsorption of Maxsorb III/HFC404A pair has been estimated experimentally at different temperatures ranging from 25 to 75 °C. Dubinin-Astakhov (D-A) and Tóth equations have been fitted with the experimental data to evaluate the adsorption isotherm, while the adsorption kinetic is evaluated by linear driving force model (LDF) and Fickian diffusion (FD) equations. The maximum adsorption capacity is 2.2 kg _R404A/kg _{activated carbon}. The numerical values of the activation energy (E_a) and the pre-exponential coefficient (D_so) are evaluated to be 3429.27 kJ/kg and 5.35×10^–13, respectively. Transient simulation modeling has been carried out to predict performance of adsorption cooling system under different operating temperatures of Maxsorb III/HFC404A. Optimum recorded coefficient for performance and specific cooling power is 0.23 and 275 W/kg, respectively.

这项工作是我们团队进行的一系列研究的一部分，目的是研究和展示具有独特特性的新材料，这些新材料适用于吸附应用。正如我们之前研究的在吸附冷却系统中使用多种氟利昂的方法一样，本文表达了将HFC404A与活性炭（Maxorb III）结合使用的研究。在25至75°C的不同温度下，已通过实验估算了对Maxsorb III / HFC404A的吸附。通过实验数据对Dubinin-Astakhov（DA）和Tóth方程进行拟合，以评估吸附等温线，同时通过线性驱动力模型（LDF）和Fickian扩散（FD）方程评估吸附动力学。最大吸附量为2.2 kg _R404A / kg_活性炭。活化能（E _a）和指数前系数（D _so）的数值分别为3429.27 kJ / kg和5.35×10 ^–13。已经进行了瞬态仿真模型，以预测在Maxsorb III / HFC404A不同工作温度下吸附冷却系统的性能。性能和比冷却功率的最佳记录系数分别为0.23和275 W / kg。
