| 1 | Adsorption performances and refrigeration application of adsorption working pair of CaCl_2-NH_3显示文摘The adsorption performance of CaCl2-NH3 is studied under the condition of different expansion spaces for adsorbent, and the relationships between adsorption performance of CaCl2-NH3 and the phenomena of swelling and agglomeration during adsorption are researched. It is found that the performance stability is related to the ratio of expansion space to the volume of adsorbent ras, and the performance attenuation is serious in the case of large ras. Severe adsorption hysteresis exists in the process of adsorption and desorption at the same evaporating and condensing temperatures, which is related to the stability constant of chemical reaction. This phenomenon cannot be explained by the theory of physical adsorption. Moderate agglomeration will be beneficial to the formation of ammoniate complex; the magnitude of expansion space will affect adsorption performance. Analysis shows that the activated energy needed in the process of adsorption for the sample with ras of 2:1 is less than that for the sample with ras of 3:1. The refrigeration performance of CaCl2-NH3 is predicted from experiments. The cooling capacity of one adsorption cycle is about 945.4 kJ/kg for the adsorbent with an ras of 2:1 at the evaporating temperature of 0℃. | WANG Liwei WANG Ruzhu WU Jingyi WANG Kai | 2004 | Science China(Technological Sciences)2004，47，2： | 9 |
| 2 | Pore structure of new composite adsorbent SiO2·xH2O·yCaCl2 with high uptake of water from air显示文摘A new composite adsorbent SiO2@xH2O@yCaCl2 which is composed of macro-porous silica gel and calcium chloride is introduced. In order to analyze its adsorption theory, adsorption and desorption isotherms, BET surface areas, pore volumes and average pore diameters of macro-porous silica gel and four composite adsorbent samples with different CaCl2 content are measured using SEM and Asap2010 apparatus. From the adsorption isotherms, desorption isotherms and lag loops, it can be deduced that the main pore structure in macro-porous silica gel and the new composite adsorbent have two shapes: taper with one top open and taper or hyperbolic taper with both ends open. Based on the analysis of pore diameter distribution and lag loop, a sketch map showing calcium chloride filled in pore of macro-porous silica gel is presented. The adsorption isotherms at 25℃ are measured. Experimental results show that the new composite adsorbent can adsorb more water than common adsorbents (macro-porous silica gel, micro-porous silica gel and synthetic zeolite 13X). In the light of the results of pore structure, adsorption isotherms and lyolysis phenomenon are analyzed. | LIU Yefeng (刘业凤) WANG Ruzhu (王如竹) | 2003 | Science China(Technological Sciences)2003，46，5： | 6 |

| 4 | Research on the chemical adsorption precursor state of CaCl_2-NH_3 for adsorption refrigeration显示文摘As a type of chemical adsorption working pair, the physical adsorption occurs first for CaCl2-NH3 because the effective reaction distance for van der Waals force is longer than that for chemical reaction force, and this physical adsorption state is named the precursor state of chemical adsorption. In order to get the different precursor states of CaCl2-NH3, the different distances between NH3 gas and Ca2+ are realized by the control of different phenomena of swelling and agglomeration in the process of adsorption. When the serious swelling exists while the agglomeration does not exist in the process of adsorption, experimental results show that the activated energy consumed by adsorption reaction increases for the reason of longer distance between Ca2+ and NH3, and at the same time the performance attenuation occurs in the repeated adsorption cycles. When the agglomeration occurs in the process of adsorption, the activated energy for the transition from precursor state to chemical adsorption decreases because the distance between NH3 gas and Ca2+ is shortened by the limited expansion space of adsorbent, and at the same time the performance attenuation does not occur. The adsorption refrigeration isobars are researched by the precursor state of chemical adsorption; results also show that the precursor state is a key factor for isobaric adsorption performance while the distribution of Ca2+ does not influence the permeation of NH3 gas in adsorbent. | WANG Liwei WANG Ruzhu WU Jingyi WANG Kai | 2005 | Science China(Technological Sciences)2005，48，1： | 5 |
| 5 | Solar-driven high temperature radiant cooling显示文摘Solar energy is widely used as one of the most important renewable energy. In addition to the growing applications of solar PV and solar water heater, solar cooling is also considered very valuable and the related researches are developing fast because of the synchronism between solar irradiance and building cooling load. Current studies mainly focus on the high temperature solar collector technique and heat-driven cooling technique, while little concern has been paid to the transport process of cool-ing power. In this paper, the high temperature radiant cooling is studied as an alternative way for transporting cooling power, and the performance of the combination of radiant ceiling and solar cool-ing is also studied. From simulation and theoretical analysis results, high temperature radiant cooling terminal shows better cooling power transportation ability against conventional air-conditioning ter-minal, and its thermal comfort is improved. Experiment results indicate that radiant cooling can en-hance the chiller's COP (Coefficient of Performance) by 17% and cooling power regeneration by 50%. According to analysis in this paper, high temperature radiant cooling is proved to be suitable for solar cooling system, and out work can serve as a reference for later system design and promotion. | SONG ZhaoPei WANG RuZhu ZHAI XiaoQiang | 2009 | Chinese Science Bulletin2009，54，6： | 4 |
| 6 | A study on multifunction heat pipe type high efficient adsorption refrigerator using compound adsorbent-ammonia显示文摘A multifunction heat pipe adsorption refrigerator is designed, which uses solidified com- pound adsorbent of CaCl2 and activated carbon as adsorbent. Two work conditions, ice-maker driven by the exhaust heat from diesel engine and air-condi- tioning powered by solar energy, are studied. SCP (specific cooling power) and COP (coefficient of per- formance) for different conditions are analyzed. The optimum average SCP and COP for the refrigerator powered by waste heat of diesel engine are 770.4 W/kg and 0.39 at about -20℃ evaporating tem- perature. The optimum average SCP and COP for the refrigerator powered by solar energy are 524.2 W/kg and 0.27 at about 5.6℃ evaporating tempera- ture. | LU Zisheng WANG Ruzhu WANG Liwei CHEN Chuanjuan | 2006 | Chinese Science Bulletin2006，51，2： | 4 |
| 7 | High-efficient thermochemical sorption refrigeration driven by low-grade thermal energy显示文摘Thermochemical sorption refrigeration powered by low-grade thermal energy is one of the energy-saving and environment friendly green refrigeration technologies. The operation principle of sorption refrigeration system is based on the thermal effects of reversible physicochemical reaction processes between sorbents and refrigerants. This paper presents the developing study on the different thermochemical sorption refrigeration cycles, and some representative high-efficient thermochemical sorption refrigeration cycles were evaluated and analyzed based on the conventional single-effect sorption cycle. These advanced sorption refrigeration cycles mainly include the heat and mass recovery sorption cycle, double-effect sorption cycle, multi-effect sorption cycle, combined double-way sorption cycle, and double-effect and double-way sorption cycle with internal heat recovery. Moreover, the developing tendency of the thermochemical sorption refrigeration is also predicted in this paper. | LI TingXian WANG RuZhu WANG LiWei | 2009 | Chinese Science Bulletin2009，54，6： | 3 |
| 8 | Heat Recovery for Adsorption Refrigeration System via Pinch Technology显示文摘An adsorption refrigeration system can be driven by low grade heat and uses natural refrigerant with the advantage of reducing the greenhouse gases emission.However,one of the weaknesses is its low efficiency and more importantly its high cost.The recovery of internal waste heat becomes therefore very important in order to improve the coefficient of performance(COP).Analysis based on pinch technology can be helpful to optimal heat recovery operation.In this paper,temperature-heat diagrams and problem tables for adsorption refrigeration systems are proposed and analyzed using Pinch Technology.The results show that pinch point is located between beds and the main waste heat needs to be recovered between beds.Dynamic characteristic(time factor)of adsorption refrigeration system is the main resistance for heat recovery.The effect of pinch point temperature difference on the system COP is not distinct.Furthermore,when the driving temperature is 90°C,the COP of adsorption refrigeration via optimization of pinch analysis is 0.73 which is fairly comparable to Li Br-water absorption refrigeration system.Pinch Technology can be adopted in different types of adsorption refrigeration systems(two-bed,four-bed,mass recovery,et al.). | PAN Quanwen SHAN He TAMAINOT-TELTO Zacharie WANG Ruzhu | 2022 | Journal of Thermal Science2022，31，2： | 2 |
| 9 | Comparison on Thermal Conductivity and Permeability of Granular and Consolidated Activated Carbon for Refrigeration显示文摘This paper focuses on the development of three types of activated carbon (AC) adsorbents, i.e. granular AC, consolidated AC with chemical binder, and consolidated AC with expanded natural graphite (ENG). Their thermal conductivity was investigated with the steady-state heat source method and the permeability was tested with nitrogen as the gas source. Results show that the thermal conductivity of granular AC with different sizes al-most maintains a constant at 0.36 W·(m·K)-1, while the value modestly increases to 0.40 W·(m·K)-1 for the con-solidated AC with chemical binder. The consolidated AC with ENG at the density of 600 kg·m-3 shows the best heat transfer performance and their thermal conductivity vary from 2.08 W·(m·K)-1 to 2.61 W·(m·K)-1 according to its fraction of AC. However, the granular AC and consolidated AC with chemical binder show the better permeability performance than consolidated AC with ENG binder whose permeability changes from 6.98×10-13 m2 to 5.16×10-11 m2 and the maximum occurs when the content of AC reaches 71.4% (by mass). According to the different thermal properties, the refrigeration application of three types of adsorbents is analyzed. | JIN Zhequan TIAN Bo WANG Liwei WANG Ruzhu | 2013 | Chinese Journal of Chemical Engineering2013，21，6： | 2 |
| 10 | Performance of cryogenic regenerator with ~3 He as working fluid显示文摘Almost all experimental and theoretical studies on regenerative cryocoolers at temperatures below 20 K mention the use of 4He as working fluid.A preliminary qualitative evaluation indicates that because of the superfluid phase transition,a working fluid of 3 He would overcome the cooling temperature limitation set by 4He.Starting with a comparison of the thermophysical properties of 3He and 4He,cryogenic regenerator simulations applied to the third/last stage of a pulse tube refrigerator,with 3He and 4He separately,were implemented to quantitatively analyze performance differences of the regenerator with respect to regenerator loss, cooling power and COP.Results conclude that 3He could significantly improve the performance of a regenerative cryocooler. | HUANG YongHua FANG Lei WANG RuZhu | 2011 | Chinese Science Bulletin2011，56，16： | 2 |
| 11 | Transportation of low-grade thermal energy over long distance by ammonia-water absorption显示文摘This paper presents the importance and the cycle choice for long-distance transportation of low-grade thermal energy, and the thermodynamic and hydrodynamic feasibility of single-effect ammonia-water absorption system for heat or cold transportation over long distance are also involved. A model of a long-distance thermal energy transportation system is built and analyzed, which shows satisfactory and attractive results. When a steam heat source at 120℃ is available, the user site can get hot water output at about 55℃ with the thermal COP of about 0.6 and the electric COP of about 100 in winter, and cold water output at about 10℃ with the thermal COP of about 0.5 and the electric COP of 50 in summer. A small-size prototype is built to verify the performance analysis. Basically the experimental data show good accordance with the analysis results. The ammonia-water absorption system is a potential pro-spective solution for the heat or cold transportation over long distance. | MA Qiang WANG RuZhu LUO LinGai XIA ZaiZhong LIN Peng | 2009 | Chinese Science Bulletin2009，54，6： | 2 |
