供暖、通风和空调（HVAC）系统最佳送风温度的选择高度依赖于系统和应用。当前ASHRAE文献为设计师选择设计送风温度提供了相当大的自由度。由于目前使用冰蓄冷系统以减少电力需求，因此有机会降低风扇能耗，以消除与冰蓄冷系统相关的制冷损失。直接向房间供应40°F的空气将减少空气量、空气分配系统的尺寸和风扇能量。本文讨论了向房间供应40°F空气的潜在问题，推荐了设计指南，并通过两个案例研究表明，在所有操作条件下，40°F空气都可以成功地供应给房间，创造舒适的环境。 关键词:送风，冷空气分配，空气扩散器，空气分配设备，空气处理器。引文:研讨会，ASHRAE交易1993，第99卷，pt。1.

The selection of the optimum supply air temperature for a heating, ventilating, and air-conditioning (HVAC) system is highly system and application dependent. Current ASHRAE literature gives the designer considerable latitude in selecting the design supply air temperature. With the current use of ice storage systems for the purposes of reducing electrical demand there is an opportunity to reduce fan energy consumption in order to eliminate the refrigeration penalty associated with ice thermal energy storage systems. The supply of 40°F air directly to the room will reduce the air quantity, size of the air distribution system, and fan energy. This paper discusses the potential problems of supplying 40°F air to a room, recommends design guidelines, and shows through two case studies that 40°F air can be successfully supplied to a room producing a comfortable environment under all operating conditions.KEYWORDS: Supply air, cold air distribution, air diffusers, air distribution equipment, air handlers.
