四面出风室内机新风送风改进方式的数值模拟

为了改善室内的新风送风效果，以美的公司的一种多联式空调系统四面出风嵌入式室内机为例，针对其特殊结构存在的新风引入问题，提出了一种改进的新风送风方式，进而利用计算机对所提出的3种工况进行数值模拟，并且对该新风送风改进方式进行评价．从模拟的结果可知，改进方式能够有效地改善室内的气流分布状况，使送风和新风得到更好的混合，温度场分布较为均匀，并且具有更好的舒适性．因此，改进的新风送风方式能使空调房间的气流组织效果更佳，在实际工程应用中具有一定的指导意义．

The numerical simulation of an improved way of indoor blower with fresh air surrounded supplying

With the purpose of find an improved way of supplying fresh air to room, based on the multi-line system＇s device which is indoor blower with fresh air surrounded supplying of Midea Company, to the problem of fresh air for its special structure, a new air supply method and numerical simulation are put forward. And then, simulation was completed at three operating condition with computer, evaluation was made for new air supplying way. According to the result of the numerical simulation, it can be seen that new way can ameliorate the air distribution effectively in the room. The blowing air and the fresh air can be mixed more adequately and the temperature distribution is symmetrical and comfortable. The improved way of fresh air can get air distribution better in room, it has some directional meaning for actual project.
