热回收型转轮复合型除湿系统的实验研究

Experimental Research on Power Consumption of the Heat Recovery Type Refrigerating-rotary United Dehumidification System

本文在转轮除湿与制冷除湿系统上增加热回收系统,降低转轮再生功耗的同时,实现转轮再生排风的循环利用,减少转轮再生排风管道,节省工程安装量。通过实验测试,与普通转轮复合除湿系统的相比,不同进风工况下,热回收型转轮复合除湿系统的总功耗降低约6%～20%。热回收型转轮复合除湿系统中热回收量约占总功耗的22%,其中板式热回收占总功耗的18%,冷凝热回收约占总功耗的4%,处理再生排风的功耗约占总功耗的8%,因此也可仅增加板式热回收来实现再生排风的循环利用。

Adding heat recovery system to the refrigerating rotary combined dehumidification system, the reactiva tion air of rotor dehumidifier becomes recycled, and the power consumption on reactivation also be decreased; At the same time, the reactivation air ducts are reduced, which can save the work of installation. The test data under different conditions confirm ： The power consumption of the heat recovery type refrigerating rotary united dehumidi fication system is 6 20% less than the common type. The recovered energy is about 2：2% of the total power consump tion in the heat recovery type refrigerating rotary united dehumidification system, 18% of which is belong to plate type heat recovery, while the other 4% is condensing heat recovery. The power consumption on handing reactivation air is about 8% of the total power consumption, so it is feasible to recycle the exhaust air of rotor simply by increas ing the plate type heat recovery exchanger.
