热泵干燥系统的研究设计

Study and Design of Heat Pump Drying System

热泵是一项高效节能技术,应用于干燥过程可以降低能耗,对于缓解我国能源紧张局面具有重要意义。为此,以带辅助冷凝器的闭路式热泵干燥系统为例,介绍了热泵干燥系统的组成及工作原理;同时,以河北太行山区的婆枣为干燥物,详细介绍了热泵单元和干燥单元的设计计算及设备选型。

Heat pump is a high efficiency energy saving technology, applied it in drying will reduce energy consumption, which is very important to our energy shortage situation. A close - circuit heat pump drying system with assist condenser is selected to introduce composition and operation principle of drying process. Design, calculation and equipment selection of heat pump unit and drying unit are introduced, with date in Taihang mountains area, Hebei Province being used as drying mass.
