In this work is proposed two performance indices of a desiccant rotor: the humidity effectiveness and the enthalpy-leak ratio. The humidity effectiveness represents the actual dehumidification as compared with the dehumidification in an ideal case, while the enthalpy-leak ratio represents the enthalpy transfer from the regeneration side to the dehumidification side. In an ideal case, the two indices approach one and zero, respectively. The effects of numerous parameters on the dehumidification performance of a desiccant rotor are investigated through numerical simulation and represented with the two indices. The results show that the performance indices are mainly determined by three nondimensional parameters each representing the thermal capacity, the sorption capacity, and the transfer capacity of a desiccant rotor. 대한설비공학회 제습로터 성능지표 제안 A Proposal for New Definition of Performance Indices of a Desiccant Rotor Article 2 설비공학 논문집, v.19, no.7, pp.537 - 544 설비공학 논문집 19 7 537 544 kci ART001084618 Desiccant rotor(제습로터) Performance index(성능지표) Humidity effectiveness(습도 유용도) Enthalpy-leak ratio(엔탈피 누설률)
