Abstract
A novel heat pipe recovery fan has been proposed in order to improve the indoor environment, which can be either a perfect supplement to the traditional desiccant technology or an alternative. Heat pipe can be applied to recycle heat and enhance solution dehumidification. This paper presents a new technological process that the heat can be derived from waste water and solar energy can be reserved to use when necessary. By applying the correlated coefficient, the performance of the system is presented in terms of dehumidification capacity and heat recovery efficiency by simulation. The effect of supplying air flow rate on the airborne pollutant transports are also illustrated based on the new fan with the indoor heat source. The results demonstrate that the best indoor rate for the present system is limited to 0.3ms–1. In addition, the the liquid to gas flow rate ratios(L/G) has a great influence on dehumidification effectiveness and heat recovery effectiveness. The conclusion can be used as reference information for the optimization of new fan design and application.
