The air-conditioned room in small space is studied by establishing the mathematical model of the air flow arrangement for energy saving. The energy saving effect is analyzed numerically at different angles under circumstance of the most common way of one-side up supply and down return. Our results show that if air supply angle is set at , the energy utilization coefficient is maximum value,and air condition reaches best energy-saving state. Our design method can be referenced valuably for the air exit design and regulating of air-conditioned room in real project.

Fluorescent/phosphorescent dual-emissive polymers or hybrids consisting of both fluorophore and phosphor have been used as self-calibrating probes and imaging reagents for cellular molecular oxygen. Oxygen selectively quenches the phosphorescence and...

Split air conditioner (SAC) plays a critical role for temperature control of buildings. In recent years, the manufacturing process of SAC tends to consider energy-saving and environmental protection factors to reduce air pollution and alleviate energy crisis. However, the design of environmental-friendly SAC will increase the manufacturing cost, thereby increasing the burden on airconditioning companies. Therefore, the eco-cost analysis of SAC is of great significance for air conditioner manufacturers. To this end, a new SAC eco-cost assessment method based on activity based costing method is innovatively proposed in this paper. In this method, a K-nearest neighbor algorithm is used to deal with the missing data in SAC samples. An environmental and non-environmental cost assessment approach is developed based on the activity-based costing method to estimate the eco-cost of SAC over its whole life cycle. In addition, the impact of energy efficiency deviation on SAC eco-cost is numerically analyzed. Finally, the proposed ecocost assessment method is programmed on a Gabi software, and validated using real SAC data from a Chinese airconditioning company. Simulation results show that the proposed method can provide an estimate of the eco-cost of SAC, thus helping airconditioning companies to improve their competitiveness in the future where energy-saving and emission reduction are increasingly important.

In this paper, we study the building air-conditioned room in the small space and establishment the mathematical numerical simulation model which is for the designing and energy saving of the air distribution, We analysis the energy effect on five types of the airflow organization based on simulation software developed by our research team to study the designing and energy saving of the air distribution, and the results show that considering both the two ways of the air distribution is more reasonable and energy-efficient.

Room temperature ionic liquids are new emerging materials. However, ionic liquids are applied mainly in Chemistry field and are rarely used in microfluidics although they are also good photoelectric medium material. Here ionic liquids are used as a new type of microfluidic fluids, and the flow performance of ionic liquids under electromagnetic drive is researched so as to promote their application in microfluidics. The flow rates can be up to 3.9μl/s and 9.7μl/s at applied direct-current potentials of 6 and 8 V, respectively, in a 0.5T magnetic field. Meanwhile the time performances of ionic liquids in electromagnetic field are researched. The experiment data are in accord with the theory results calculated by the numerical simulation.
