Abstract

The invention discloses a solar and soil source combined heat pump structure. The solar and soil source combined heat pump structure comprises a solar absorption device, a ground heat exchanger, a solar power driver and a heat pump unit. Solar energy is subjected to heat energy conversion and electric energy conversion, and the solar energy and terrestrial heat can be utilized comprehensively. The invention further provides a control method of the solar and soil source combined heat pump structure. By reasonably selecting a valve switch and the corresponding opening degree, the absorption and emission efficiency of heat by circulating water is further improved. By means of the solar and soil source combined heat pump structure and the control method thereof, the defects in the prior art can be overcome, and heat efficiency of a combined heat pump is improved.

Description

technical field [0001] The invention relates to the technical field of a heat pump device, in particular to a solar energy and soil source composite heat pump structure and a control method thereof. Background technique [0002] With the development of society, people's awareness of environmental protection is also constantly improving. Due to the obvious advantages of environmental protection and energy saving of soil source heat pump, it has been promoted to a certain extent in recent years. However, after a period of use, the imbalance of the soil temperature field will appear in the area where the device is used, and this problem is particularly prominent in the cold northern regions. Chinese invention patent application CN103062820 A discloses a soil source heat pump and solar energy combined heat storage heating system, which ensures the balance between the heat absorbed from the earth in winter and the heat released to the earth in summer, and ensures that the soil so...
