注意到冷空气分配（42degF-49degF送风）的好处，即降低了首件成本、降低了建筑高度、降低了能源和电力需求成本，以及改善了舒适度和室内空气质量。指出在冷空气分配系统中增加风扇驱动的混合箱可以减少或消除节能。列举的例子证实，使用目前可用的扩散器，直接向空间供应42degF-49degF空气是可行和可取的，以提供优越的室内空气扩散和最大程度的节能。 表示需要更多关于42degF-49degF空气扩散器性能的公布测试数据。关键词:空调、送风、气温、风道末端、扩散器、低温、节能、性能。引文:研讨会，ASHRAE交易，第97卷，Pt。1991年，纽约

Notes the benefits of cold air distribution (42degF-49degF supply air) of reduced first cost, reduced building height and reduced energy and electricity demand cost plus improvements in comfort and indoor air quality. Points out that energy savings may be reduced or eliminated by the addition of fan-powered mixing boxes to a cold air distribution system. Cites examples which confirm that direct supply of 42degF-49degF air to a space is practical and desirable using currently-available diffusers, to provide superior room air diffusion and maximum energy savings. States there is a need for more published test data on the performance of diffusers with 42degF-49degF air.KEYWORDS: Air conditioning, supply air, air temperature, air terminals, diffusers, low temperature, energy conservation, performance.
