Аннотация

An alternative technology that surpasses the efficiency of conventional vapor compression cycle is needed to meet the increased demand for air conditioning. As one of the candidates, we analyzed a membrane heat pump. The membrane heat pump is designed to maximize the cycle efficiency by applying hydrophobic water-passing dense membrane in heat exchangers, which can decrease energy consumption in dehumidification and vapor compression process. This new heat pump separates air-conditioning process into dehumidification and latent heat cooling. Air is dehumidified through steam separation membrane and cooled by water cooling loop. For cooling water cycle, vacuum pump and circulation pump are equipped to establish semi-open water cycle. From the simulation, membrane heat pump showed COP improved more than 20% of conventional system. This study modeled the heat and mass transfer of membrane heat pump in each process and analyzed heat exchanger operating principle by considering membrane's vapor permeability for main two objects.
