热泵空调系统可燃混合物的安全运行环境预测

THE EVALUATION ON AVOIDING FIRE DANGER FOR FLAMMABLE MIXTURE IN HEAT PUMP AND AIR CONDITIONER SYSTEMS

提出以最小运行面积及最小运行面积比作为衡量热泵空调系统运行可燃性和安全性外部条件新概念以及含有两种以上可燃纯质混合物的燃烧极限计算式，对最小运行面积比的影响因素进行了分析。可燃组元燃烧低限均大于１２（体积百分比）的可燃混合物，最小运行面积比远小于实际值。

The new idea of the miniumum for operating area and the ratio of the miniumum for operating area have been proposed in ordor to evaluate the offect of on the safe operation of flammability cycle system.Through analyze it is shown that the miniumum operating area is smaller than real value when the lower flammable limit of the mixture is less 12.
