本文的主要目的是对在室温（中性温度）或接近室温（中性温度）下从专用室外空气系统供应空气的当前实践提出质疑，并开发一种以节能和经济高效的方式选择送风条件的方法。提出了有关送风干球温度、露点温度和末端再热的假设。然后对这三个假设进行测试，并发现它们是正确的。通常，建议专用室外空气系统的送风温度不高于55ºF（13ºC）。建议的送风露点温度是在保持空间相对湿度不超过40%或送风露点温度约为44ºF（7ºC）的情况下提供所有潜在冷却所需的温度。最后，证明了通常不需要终端再热来防止过热- 44-55ºF（7-13ºC）的冷却为照明和设备负荷为3-5 W/ft2（32-54 W/m2）的空间提供空气干球温度。这一结论适用于设计居住密度为每1000平方英尺（93平方米）7至90人以上的空间。更大的空间设计占用密度有更多的通风空气，超过了去除3-5 W/ft2（32-54 W/m2）内部发电的要求。在中性温度下供应空气会将几乎所有的空间敏感负荷转移到分布式并行冷却系统上，这会带来巨大的初始成本和运行成本损失，这种做法通常是不合理的。自动控制，一个超出本文范围的主题，有望提供进一步提高低送风条件经济效益的潜力。单位:双引用:研讨会论文，佐治亚州亚特兰大，2001年

The central thrust of this paper is to place into question the current practice of supplying air from dedicated outdoor air systems at or near room temperature (a neutral temperature) and to develop a methodology for selecting the supply air conditions in an energy- and cost-effective manner. Hypotheses are advanced concerning the supply air dry-bulb temperature, dew-point temperature, and terminal reheat. The three hypotheses are then tested and found to be correct. In general, it is recommended that the supply air temperature from the dedicated outdoor air system be no higher than 55ºF (13ºC). The recommended supply air dew-point temperature is whatever it takes to provide all of the latent cooling while maintaining the space relative humidity at no more than 40%, or a supply air dew-point temperature of approximately 44ºF (7ºC). Finally, it was demonstrated that terminal reheat is generally not required to prevent over-cooling with 44-55ºF (7-13ºC) supply air dry-bulb tempera-tures for spaces with a combined lighting and equipment load of 3-5 W/ft2(32-54 W/m2). This conclusion applies to spaces with design occupancy densities from 7 to more than 90 people per 1000 ft2(93 m2). Greater space design occupancy densities have more ventilation air than required to remove the 3-5 W/ft2(32-54 W/m2) of internal generation. Supplying the air at a neutral temperature shifts virtually all of the space sensible loads out onto the distributed parallel cooling system at a huge first and operating cost penalty, a practice that normally cannot be justified. Automatic controls, a subject beyond the scope of this paper, are envisioned to offer the potential to further improve the economic benefits of the lower supply air conditions.Units: Dual
