在一个大多数新办公空间都装有空调，几乎没有任何新工厂空间被冷却的社区里，这是一种双重标准的情况，在现代社会应该是不可容忍的，这种说法并不具有政治性。如果空调在经济上是可行的，那么通过提高劳动力的精神和身体效率，空调投资的回报是有保证的。典型的澳大利亚工厂的问题是，空调在经济上不可行。因此，在大多数情况下，除了强制通风之外，没有什么是必要的，偶尔在高温过程中，还需要额外的风扇和/或排气罩。工厂管理层传统上寻求通过通风降温。这些措施的用意很好，可以缓解这种情况，但通风不会将温度降低到环境条件以下。 应该记住，工厂温度高于26.67摄氏度的影响是基于效率、福利、安全和员工关系进行调查的正当理由。蒸发冷却仅受湿球温度的限制，在经济上可行，并将显示出与办公室空调相同的工业投资回报。制冷提供了我们最好的冷却，蒸发冷却显然是次要的。然而，拥有和运行蒸发冷却器的成本要低60%到80%，蒸发冷却器可用于冷却结构较薄的热建筑，而在这些建筑中，冷冻冷却的成本高得令人望而却步。引文:德克萨斯州达拉斯ASHRAE交易会第82卷第1部分研讨会

It is not politic to state that, in a community where most of new office spaceis air conditioned and hardly any new factory space is even cooled, this is adouble standard situation which should be intolerable in a modern society.Where air conditioning is economically feasible, the return on investment inair conditioning from an increase in mental and physical efficiency of the workforce is assured.The problem with the typical Australian factory is that air conditioning isnot economically feasible. Therefore, in the majority of cases, nothing isdone except mandatory ventilation, supplemented occasionally by additional fansand/or exhaust hoods over hot processes.Factory management traditionally seeks cooling through ventilation. Thesemeasures are well intended and will relieve a situation, but ventilation alonewill not reduce temperatures below ambient conditions.It should be remembered the effect of temperatures above 26.67C in thefactory justifies investigation on the basis of efficiency, welfare, safety andemployee relations.Evaporative cooling, limited only by the wet bulb temperature, is economicallyfeasible and will show the same worthwhile return on investment in industryas air conditioning does in the offices.Refrigeration provides our best cooling and evaporative cooling is clearly secondary to it.However, it is 60% to 80% cheaper to own and operate evaporative coolers which can be used to cool hot, thinly constructed buildings where refrigerated cooling is prohibitively expensive.
