摘要
热泵干燥具有节能、低温干燥及环境友好等特点,控制热泵干燥装置运行在较佳的状态,是保证热泵干燥装置效率和可靠性的基础。以带循环空气旁通的封闭式热泵干燥装置为例,对热泵干燥装置的调控方法进行了分析,给出了装置的被控参数和一组较佳的控制参数,并建立了各控制参数的计算公式。
A heat pump dryer can work with high energy efficiency and friendly environment condition at low temperature. Controlling heat pump dryers running with suitable states is basic for its high efficiency and reliability. In this paper, the methods to control a heat pump dryer were analyzed, a group of controlling parameters and controlled parameters was selected, and equations for determining controlling parameters were given for closed air circuit heat pump dryers with cycling air by-pass.
