Why is there almost no air conditioning in primary schools in Nan 'an District of Chongqing?

Climate conditions, energy consumption and cost considerations.

1, climatic conditions: Nan 'an District of Chongqing is located in the urban area of Chongqing, and belongs to subtropical humid monsoon climate. High temperature and humidity in summer and cold in winter. The temperature in Nan 'an District is high in summer, but the duration is short, while the heating time in winter is long. Due to the long cold season and short hot period, primary schools pay more attention to the installation of heating equipment, reducing the investment in air-conditioning equipment.

2. Energy consumption and cost considerations: Air conditioning is a kind of equipment with high energy consumption, especially in hot summer weather, and long-term operation of air conditioning will consume a lot of electricity. As a public place, schools need to bear large energy costs and maintenance costs. In order to save energy and reduce expenses, some schools will choose not to install air conditioning equipment.
