在1956—1957年间,国外许多杂志发表过关于加拿大安大略《弗鲁特斯托皮》矿山空气调节新方法的报道。这种方法的实质如下。冬天,在把外部冷空气送入矿山井巷以前,让它先通过一个专门的地下硐室,靠近硐室顶板,利用喷射器不断喷射从矿井中排出的水。由于热水和冷空气之间热交换的结果,使后者得到加热,而水发生冻结,并以冰的形式沉积在硐室底板上。硐室容积的选择应在暖季到来之前能满足积冰的需要。在参数选择得适当的情况下,全套调节设
Between 1956 and 1957, many foreign magazines published a report on a new method of air conditioning in the “Frutostoma” mine in Ontario, Canada. The essence of this method is as follows. In winter, before sending cold outside air into a mine shaft, let it pass through a dedicated underground chamber, near the top of the chamber, and continue to inject water from the mine using injectors. As a result of the heat exchange between hot and cold air, the latter is heated and the water freezes and deposits as ice on the chamber floor. The chamber volume should be chosen to meet the need of ice accumulation before the warm season arrives. In the case of the appropriate choice of parameters, a full set of settings
