一、概述在通风空调领域里的节能问题是值得重视的。其途径之一是通过减少送风量来减少空调负荷。工作区域的空调如就地送风空调、下部送风空调等,就是这样的送风方式。工作区送风空调特别是下送上回的方式,实际上是最早的送风方式之一。由于出风口距离人体较近,处理不好常给人以吹风感,并且送风量大,风口数多而不易布置,同时容易扬起灰尘,所以长期以来较少应用。对于此种送风方式也就缺乏进一步认识和研究。六、七十年代以来,由于节能要求,美、德、苏联和日本等均有人重新对此类空调方式予以研究和使用,如在电算机房、
I. Overview Energy-saving issues in the field of ventilation and air conditioning are worthy of attention. One of the ways is to reduce the air conditioning load by reducing the amount of air supply. The air conditioning in the work area, such as local air-conditioning air-conditioning, lower air-conditioning air conditioning, etc., is such an air supply method. Workplace air conditioning, especially the way it is sent back and forth, is actually one of the earliest air delivery methods. Since the air outlet is relatively close to the human body, poor handling often gives a feeling of blowing hair, and the air volume is large, the number of air outlets is large and it is difficult to arrange, and at the same time it is easy to raise dust. Therefore, it has been used for a long time. There is a lack of further understanding and research on this style of air supply. Since the 1960s and 1970s, due to energy saving requirements, the United States, Germany, the Soviet Union and Japan have all re-investigated and used such air-conditioning methods, such as in computer rooms,
