| Abstract | A calculation model is established to obtain the nationwide distribution of heating and cooling loads under the 'carbon neutral' target. The model takes the load limits of a region or city as its target and incorporates the energy efficiency standards of buildings and urban planning standards. Meanwhile, the calculation of national heating and cooling load is achieved using the degree-day method and the load inversion method. Research on building loads was conducted using ten cities from five thermal zones across China, including Harbin, Hohhot, Lanzhou, Beijing, Chongqing, Wuhan, Fuzhou, Guangzhou, Kunming, and Guiyang. The study covered the energy consumption characteristics of different types of buildings, those in different thermal zones, and those with simultaneous cooling and heating loads during the same period, such as cold storage facilities, supermarkets, and hotels. Based on the distribution of national heating and cooling loads, research was also briefly analyzed on low-carbon energy supply options. The results showed that the daily, monthly, and annual loads and load index values of various buildings in the same city are mainly affected by the set load limit value. The load proportion of different types of buildings is primarily influenced by their corresponding building areas. Furthermore, the heating and cooling loads in different thermal zones are mainly influenced by the outdoor calculated temperature. It can be noted that Mohe City has the highest heating load due to the lowest calculated outdoor temperature in the heating month. Since Turpan has the highest calculated outdoor temperature in the cooling month, it has the highest cooling load. As a promising energy supply method for buildings in the future, heat pumps could achieve more efficient use when combined with seasonal energy storage. |
