本文介绍了冻干机的热回收系统并进行了热回收的能量分析。本系统在升华阶段,利用制冷压缩机冷凝器排放的热量,这意味着制冷机作为热泵运行。这样,不仅节约了升华热而且降低了压缩机的能耗及减少冷却水消耗量。
This article describes the heat recovery system of a lyophilizer and performs an energy analysis of the heat recovery. In the sublimation stage of this system, the heat released by the refrigerant compressor condenser is utilized, which means that the refrigerator operates as a heat pump. This not only saves sublimation heat but also reduces compressor energy consumption and cooling water consumption.
