一、车间的局部冷却在一般工程计算中,由干操作工人的发热量仅仅占总热负荷的1～3％(见图1),所以一个设计者应善于用各种可能的方法仅仅去冷却操作工人所占的工作地点。按作者的观点,工厂空调最好的方法是采用点冷却或者是操作区域的面冷却。这种概念是向工人提供舒适的条件而不是去空调整个车间。这一点可以用仅 First, the local cooling of the workshop In the general engineering calculations, the heat generated by dry workers only accounts for 1 to 3% of the total heat load (see Figure 1), so a designer should be good at just cooling with all possible methods. The place of work of the operating worker. According to the authors, the best way to air-condition a factory is to use spot cooling or face cooling in the operating area. This concept is to provide workers with comfortable conditions rather than to air-conditioning the entire workshop. This can be used only
