Conventionally, a museum storeroom using an air-handling unit have been provided, under a constant-temperature and constant-humidity condition, by ice storage AC systems, boilers and an electrical heating system to meet its cooling and heating needs in the air-conditioning process, which gives rise to lots of power consumption. A helpful approach to this problem is an outdoor AHU integrated with a water-source heat pump system, validating the energy savings of exceeding 50% in the heating aspect by means of a statistic analysis of the full scale experimental validation. Furthermore, the overall effect would reach 46% if it took cooling and dehumidification into account. Because a water-source heat pump system has a precooling design in relation to AHU, it can obtain an improvement of 5% in dehumidifying capability after readjusting the sensible heat ratio. This study analyzes the optimal operational strategy further. Through raising air temperature parameters of the dehumidifying coil as a priority, it can save power consumption by 28%. While operating at partial load, it can simultaneously raise the chilled water supply temperature at the precooling coil, in order to increase the overall energy-saving effect. A reference for energy-saving operation strategy of the Museum is suggested by the results of this study, and also provides a design application for AHU for use in exhibition building. |
