Note :
① Rated efficiency: The total irradiance on the daylighting surface of the collector is 1000W/㎡, and the temperature difference between the average temperature of the collector and the ambient air temperature is 50°C. Calculate the efficiency value of the solar collector according to the instantaneous efficiency equation of the collector's daylighting area.
② Rated power: The total irradiance of the collector lighting plane is 1000w/㎡, and the collector power when the temperature difference between the average collector temperature and the ambient air temperature is 50 ° C is equal to the product of the rated efficiency and theday lighting area and 1000W/㎡.
