当建筑节能热风愈刮愈烈时,国内节能玻璃市场也要得空前活跃。节能玻璃的研发、生产重心方向,已悄然从热反射玻璃、中空玻璃开始转向对于低辐射镀膜玻璃(Low—E玻璃)的研究和生产上来。同时由于其优越的隔热性能,受到消费者的青睐。虽然目前国内低辐射节能玻璃的使用和研发都有进步,但是和发达国家相比还有较大差距。面对这现象,玻璃生产厂商们,越发关注未来我国节能玻璃的发展前景和走向。 相似文献

In the present study, the surface of cylinder head, piston, exhaust and inlet valves of a four stroke direct injection and single cylinder diesel engine has been coated with partially stabilised zirconia (PSZ) by the plasma spray method. The coated engine was tested with the neat diesel and methyl ester of neat Nerium oil. The performance and emission results were compared with the uncoated engine fuelled with diesel and methyl ester of Nerium oil (MEON). Specific fuel consumption of the PSZ-coated engine was lower at all loads, because of the insulation effect of coating and changes in combustion process due to coating. The brake thermal efficiency of PSZ-coated engine fuelled with MEON is 3.8% higher than uncoated engine fuelled with MEON. The emission for the PSZ-coated engine with diesel was improved compared with uncoated engine except NOx. 相似文献

Aluminum curtain wall system is commonly used in high-rise residential complex. For the energy-efficient curtain wall system, the insulation performance of the fastening unit, which enjoins the curtain wall unit to the slab, should be improved because in Korea, hot water pipes for radiant heating are typically installed on the slab in residential buildings. However, this fastening unit composed of metals with high thermal conductivity, acts as a thermal bridge that increases heat loss. Therefore, in this study, we aim to develop a more effective insulation method for the fastening unit. Three alternative fasteners coated with urethane foam and insulation paint were selected (Case 1: using the existing fastener; Case 2: coating the upper part of fastener with urethane foam; Case 3: coating the entire surface of fastener with insulation paint; Case 4: coating the upper part of fastener with urethane foam and the lower part with insulation paint). The heat loss and economical efficiency of each case were analyzed through the three-dimensional annual transient heat transfer simulation and payback period method, respectively. Case 4, compared to Case 1, was found to show the best performance of reducing the annual heat loss by 8.14%. From an economical efficiency perspective, however, Case 2 was found to have the shortest payback period of 2.27years. 相似文献
