当前人工配制混合气得到了广泛推广,用于国民经济,特别是节流低温系统的多组份制冷剂。其配制方法或是静态的,或是采用动态的。文献中介绍了静态方法的典型装置,其生产能力6m~3/d。在接近于理想气体状态的压力下,气体组份在混合器中混合。这可用组份分压来控制配制气体混合物的过 The current manual preparation of mixed gas has been widely promoted for the national economy, especially the multi-component refrigerants throttling low temperature system. The preparation method is either static or dynamic. The literature describes a typical static method device, the production capacity of 6m ~ 3 / d. At pressures close to the ideal gas state, the gas components are mixed in the mixer. This can be used to control the partial pressure of the compound gas mixture
