Cooling performance of evaporative cooling pad-fan unit in greenhouse in hot and humid environment

Based on a continuous measurement of temperature and humidity inside a greenhouse equipped with cooling pad-fan system in Shanghai, verifies the cooling effect of the greenhouse in hot and humid climate. Through analysing the evaporative cooling efficiency and the temperature gradients according to the test data, verifies the thermal environment model of greenhouse, and discusses the influence of outdoor environment parameters such as air temperature, relative humidity and solar irradiance on cooling capacity of greenhouse.
