Abstract

This paper aims to evaluate how much money could be saved by using a radiative cooling appliance mounted on the roofs if it is widely used in Chengdu. In 2018, Chinese people consumed electric energy in air conditioning most, arriving at 34% of the total use in that field in the whole world with a sharp increment. Meanwhile, Chinese refrigeration electricity consumption represented above 15% of total electricity consumption. The energy shortage impacts a lot, from national development to the living for the public. In fact, some people used to invent some devices like roof cooling technology, which could decrease the temperature in the house to replace the air conditioner in refrigeration for energy saving and decrease people's expenditure. Therefore, the author plans to establish a model to gain a function of the number of the temperature decreased in this way by its theory and provided physical functions and plug the collected data on Chengdu into the formula to judge whether this radiative cooling technology could bring profit to Chengdu public for a long time through another model established based upon the calculation methods and data. In the end, the author finds that the roof cooling device is beneficial to the citizens living in Chengdu in the economic aspect.
