Effect of Temperature Differentials on Condensers of Split-Type Air Conditioners in Apartment Buildings

Analyzing the effects of heat rejection from condensers of split-type air-conditioning units at lower-floors of MLABs （multi-level apartment buildings）, using field measurements to monitor environmental conditions and condenser operation, revealed increases in the inlet air temperature at the condensers at the upper floors, which in turn increased the power and energy requirements for these units and decreased their cooling capacities. Results indicated that a decrease of up to 16,000 tons in cooling capacity and an increase of up to 67.2 MW in the national peak load demand might be reached for a 4 ℃ temperature differential for Kuwait conditions. It is recommended that the condensers be placed in the wind pathway to minimize the impact of heat rejection and stack effect and to optimize the operation of split-type air-conditioning units, and that other factors regarding installation setup and location are investigated.

漫瀚剧旋律溯源

本文通过将漫瀚剧音乐的旋律与漫瀚调、二人台的旋律特点进行比较分析,试图找出他们的一些共性与内在联系。在某种程度上,兼论与内蒙古相邻省份传统音乐形态作为的辅助作用,内蒙古周边传统音乐与内蒙古西部地区传统音乐的融合的影响。目的是为内蒙古西部地区民族民间音乐的研究提供一些参考依据的同时也希望从旋律的来源上角度解读漫瀚剧音乐创作的一些技术性理念。
