Background

This section provides background information related to the present disclosure only and is not necessarily prior art.

With the progress of science and technology and the development of times, the requirements of people on the indoor environment quality are continuously improved, and meanwhile, the building energy consumption is greatly improved. The energy supply of the existing buildings mainly depends on fossil energy, so that a large amount of fossil energy is consumed, and the atmospheric pollution is also aggravated. Therefore, the development of renewable energy sources is enhanced, clean energy sources are greatly promoted, and the method is an inevitable way for realizing sustainable development.

Solar energy and wind energy are common renewable energy sources, at present, the solar energy and the wind energy are mainly utilized in the forms of photo-thermal energy, photoelectric energy, wind power and the like, but due to the intermittent and unstable properties, the phenomena of 'light abandoning' and 'wind abandoning' are serious, and the large-scale development of the renewable energy sources is restricted; on the other hand, as the user load has the characteristics of the user load, the change rule of the user load is inconsistent with the change rule of the renewable energy power generation, so that part of the renewable energy power generation can not be on line. In this case, not only a large amount of power is wasted, but also the reliability of power supply to the user load is reduced.

The soil source is the same as solar energy and wind energy, and also belongs to renewable energy sources. However, in cold regions, especially in severe cold regions, the heat load of buildings is significantly greater than the cold load, and the heat quantity extracted from the soil is far greater than the heat gain quantity of the soil during long-term operation, so that the cold accumulation phenomenon of the soil is caused. The soil cold accumulation problem will seriously influence the heat exchange efficiency of the buried pipe in the later operation stage, will cause the shutdown of the heat pump unit when serious, shorten the working life of the heat pump unit.
