Heat pump를 적용한 액체식 제습 시스템의 겨울철 가습 운전에 대한 실험적 연구

초록

The performance of regenerator in heat pump integrated liquid desiccant (LD) system was investigated for the operation in winter. The performance parameters for regenerator were the regeneration effectiveness and enthalpy exchange effectiveness. There were five independent parameters of inlet air temperature, inlet air humidity ratio, inlet solution temperature, concentration of solution and liquid-to-gas ratio. The experimental model was constructed using an adiabatic cross flow regenerator with lithium chloride solution. Based on 2k and 3k factorial design method, total 48 experiment sets were designed to develop prediction models for two performance parameters. The results showed that the solution temperature and liquit-to-gas ratio have significant effects on the regeneration effectiveness and enthalpy exchange effectiveness of regenerator. In addition, the amount of humidification was ranged from 3.23 g/㎏a to 51.18 g/㎏a, therefore it was enough for humidification system in winter.
