[0002] In the development process of air conditioners, the same set of air conditioner units under the same natural climate conditions, the refrigeration and heating effects in the laboratory and the human body thermal comfort experience in the house are significantly different, especially in the heating mode. The reason is that the laboratory and the house have different maintenance structures, the wall, door and window building materials have different heat conductivity, the house heat load and the house heat dissipation rate are different, but no matter what type of room, the cold and heat output of the air conditioner unit is constant, the mismatch between the room cold and heat demand and the refrigeration and heating output of the air conditioner leads to poor user thermal comfort experience.

[0003] And the national standard clearly requires that the refrigerating capacity of the air conditioner is determined according to the climate conditions of Nanjing City, Jiangsu Province, China, which is a constant. China is vast, and in order to adapt to the local climate characteristics, the people in each region design houses according to local conditions, so that the houses in China are very diverse.
