对蒸发冷却式空调的设计与热工计算方法的一些看法
Some views on design and thermal performance calculation methods of evaporative cooling air conditioning systems
摘要：
干热地区应采用蒸发冷却方式实现空调，利用室外干燥空气作为空调的驱动能源而节能。从制冷过程看，蒸发冷却主要包括直接蒸发冷却和间接蒸发冷却两种方式；从载冷介质看，直接或间接蒸发冷却技术均可用来制备冷水或冷风。提出一种统一描述各种蒸发冷却方式性能的方法，并在焓湿图上确定不同的蒸发冷却方式适宜气候区，给出几种不同的蒸发冷却空调的系统方式的选择与设计方法，为蒸发冷却空调的设计与热工计算提供一些参考依据。
Abstract：
Evaporative cooling technology is the best and most recommended way for air conditioning in dry-hot regions, by which outdoor dry air is used as the driving force to reduce energy consumption. It can be divided into direct evaporative cooling (DEC)technology and indirect evaporative cooling (IEC) technology based on cooling process, and both cooling air and cooling water can be produced by either DEC or IEC technology. Puts forward a unified method to describe the performance of all kinds of DEC or IEC technologies. Divides different zones in the psychrometric chart for correspondingly using IEC or DEC technologies. Presents system design and selection methods for different evaporative cooling technologies, providing reference for design and thermal performance calculation of evaporative cooling systems.
