چکیده
In this study, to increase the heat and mass transfer coefficients in the system, a combination of liquid desiccant such as lithium chloride (LiCl) and hybrid nanoparticles of multi-walled carbon nanotubes (CNT-MW) Aluminum Oxide (Al2O3) and silicon oxide (SiO2) has been used. Poly-Vinyl Pyrrolidone (PVP) surface activator or surfactant has been used for complete stability of hybrid nanoparticles in lithium chloride (LiCl) desiccant solution and liquid water. By the experimental data, heat and mass transfer coefficients in the system have been determined in a relational way for different combinations of nanoparticles and adsorbents. The effect of important parameters such as air flow intensity and desiccant liquid, air temperature and humidity, temperature and composition of incoming desiccant liquid nanofluid on the efficiency of the system has been studied. And from there the exergy analysis of the system has been done. In this way, the best operating conditions for the better performance of the system containing liquid desiccant nanofluid have been determined. The results of this research have clearly shown that, changes in the air humidity and temperature have been increased by adding the hybrid nanoparticles to LiCl/H2O liquid desiccant.  In this regard, the mass transfer rate has been improved from 3.41% to 28.3% and the heat transfer rate has been improved from 4.18% to 29.11%. So, the average improvement has been 23.23% and 22.22%, respectively. Adding hybrid nanoparticles to LiCl/H2O liquid desiccant has increased the mass transfer coefficient from 17.42% to 29.26% and the heat transfer coefficient from 19.83% to 33.55%. Therefore, according to these results, the average value of improvement in mass and heat transfer coefficients has been about 22.73% and 26.51%, respectively.

بررسی تجربی نانوذرات هیبریدی در ماده دسیکنت خشک‌کن مایع LiCl به عنوان نانوسیال بر کارایی سیستم رطوبت زدائی جذبی
چکیده [English]
در این مطالعه برای افزایش ضرایب انتقال حرارت و جرم در سیستم، ترکیبی از خشک‌کننده مایع مانند کلرید لیتیوم (LiCl) و نانوذرات هیبریدی نانولوله‌های کربنی چند جداره (CNT-MW)، اکسید آلومینیوم (Al2O3) و اکسید سیلیکون (SiO2) استفاده شده است. فعال کننده یا سورفکتانت سطحی پلی وینیل پیرولیدون (PVP) برای پایداری کامل نانوذرات هیبریدی در محلول خشک کن لیتیوم کلرید (LiCl) و آب مایع استفاده شده است. با داده های تجربی، ضرایب انتقال گرما و جرم در سیستم به صورت رابطه ای برای ترکیب های مختلف نانوذرات و جاذب ها تعیین شده است. تأثیر پارامترهای مهمی مانند شدت جریان هوا و مایع خشک‌کننده، دما و رطوبت هوا، دما و ترکیب نانوسیال مایع خشک‌کننده ورودی بر راندمان سیستم مورد بررسی قرار گرفته است. و از آنجا تحلیل اکسرژی سیستم انجام شده است. به این ترتیب بهترین شرایط عملیاتی برای عملکرد بهتر سیستم حاوی نانوسیال خشک کن مایع تعیین شده است.

نتایج این تحقیق به وضوح نشان داد که با افزودن نانوذرات هیبریدی به خشک‌کننده مایع LiCl/H2O، تغییرات در رطوبت و دما افزایش یافته است. در این راستا، نرخ انتقال جرم از 41/3 درصد به 3/28 درصد و نرخ انتقال حرارت از 18/4درصد به 11/29 درصد بهبود یافته است. بنابراین میانگین بهبود به ترتیب 23/23 درصد و 22/22 درصد بوده است. افزودن نانوذرات هیبریدی به خشک کن مایع LiCl/H2O ضریب انتقال جرم را از 42/17% به 26/29% و ضریب انتقال حرارت را از 83/19% به 55/33% افزایش داده است. بنابراین، با توجه به این نتایج، میانگین مقدار بهبود در ضرایب جرم و انتقال حرارت به ترتیب حدود 73/22 و 51/26درصد بوده است.
