Research on Energy Saving Potential for Dedicated Ventilation Systems Based on Heat Recovery Technology
Zhang, Lian; Zhang, Yu-Feng - In: Energies 7 (2014) 7, pp. 4261-4280
Research results have identified the use of heat pipe heat exchangers (HPHXs) for heat recovery as a way to reduce the pre-cooling and re-heating energy. This paper suggests decoupling dehumidification from cooling to reduce energy consumption. The feasible usage and the energy saving potential...
