在辐射热较强,劳动强度较大或有毒有害而又固定的工作地点,夏天是我们需要防暑降温的一个重点。对在这种场所工作工人的合理的劳动条件改善不仅能保证工人同志的劳动健康,而且会有效地提高劳动生产率。目前,对从事这种作业的工人(如锻工、锅炉工、铸造工、挂瓦工、固定点喷漆工等)最好的通风降温办法是用喷雾风机吹一定湿度的冷风,但这种风机吹风面积大,笨重不易搬动,且需要附设供水管与排水沟,所以引起了实际使用中的一些问题。例如,在锻工锻打工件时,由于吹风面涉及到工件,就会加速工件的冷却速度。从而,需增加锻 In workplaces where radiant heat is strong, labour intensity is high, or where poisoning is harmful and fixed, summer is a key point for us to need heatstroke prevention and cooling. The improvement of reasonable working conditions for workers working in such places will not only ensure the comrade labor of workers, but also effectively increase labor productivity. At present, the best ventilation and cooling method for workers engaged in such operations (such as forging workers, boiler workers, foundry workers, bricklayers, fixed-point painters, etc.) is using a spray fan to blow cool air of a certain humidity, but this type of fan blows Large area, heavy and difficult to move, and the need for additional water supply pipes and drains, so it caused some problems in the actual use. For example, when forging a workpiece, because the blowing surface involves the workpiece, the cooling rate of the workpiece is accelerated. Thus, need to increase forging
