考虑到氨在过去和现在的广泛使用，值得注意的是，有关氨蒸发器设计的信息非常少。对于传热和压降计算，需要至少以质量流量、蒸汽质量和温度为变量的实验数据或关联式，即使忽略了流型等可能的参数。本文分析了作者在工业规模氨蒸发器上的早期实验工作（1）的数据。对单相数据的分析提供了一些令人惊讶的结果。提出了一种新的关联式，该关联式可能具有普遍适用性- 相传热。文中还讨论了两相压降的计算方法。提出了一种理论，认为相相互作用产生的现象与单相效应无关。引文:ASHRAE交易，第80卷，第2部分，蒙特利尔，QC

Considering the wide use of ammonia in the past and at present, it is remarkable how little information pertaining to the design of ammonia evaporators is available. For heat transfer and pressure drop calculations, experimental data or correlations with at least mass flow rate, vapor quality, and temperature as variables are needed, even if possible parameters like flow patterns are ignored.In this article, data from author's earlier experimental work (1) on an industrial sized ammonia evaporator are analyzed. Analysis of single phase data provided some surprising results. A new correlation, which is likely to have general applicability, is proposed for two-phase heat transfer. Methods for calculating two-phase pressure drop are also discussed. A theory is put forward suggesting that the phenomena due to interaction of phases are independent of single phase effects.
