To explore the potential of passive radiative cooling in hot-summer and cold-winter zone represented by Hangzhou,the influence of relative humidity on the potential of passive radiative cooling was preliminarily evaluated using the selective independent approach.An increase in temperature and relative humidity significantly reduced the potential of passive radiative cooling technology,and the influence of relative humidity was more obvious.Hangzhou has an average blackbody radiation cooling power of up to 47 W/m2 under the worst working conditions in the last two decades,with an average sky temperature drop of about 8℃It has a good cooling potential in the spring and fall seasons of a typical year,and the radiative cooling technology can be used as a cooling compensation tool in the transitional season.Therefore,radiation refrigeration technology has certain application prospects in hot summer and cold winter areas such as Hangzhou.
