Abstract

The invention discloses a solar ground-source heat pump system which comprises a solar heat collector and a buried pipe and also comprises a first water tank, a second water tank and a mixed water tank, wherein a first heat exchanger is arranged between the solar heat collector and the first water tank; a first water pump is mounted on the first heat exchanger; a second heat exchanger is arrangedbetween the buried pipe and the second water tank; a second water pump is mounted on the second heat exchanger; the first water tank communicates to the mixed water tank through a first bidirectionalgear pump; the second water tank communicates to the mixed water tank through a second bidirectional gear pump; the solar heat collector communicates to the buried pipe through a third bidirectional gear pump; and pressure relief valves are separately arranged on two sides of the third bidirectional gear pump. The system disclosed by the invention can improve the defects in the prior art, and thepressure fluctuation of system operation is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of renewable energy, in particular to a solar ground source heat pump system and a control method thereof. Background technique [0002] As the use of fossil energy pollutes the environment, people pay more and more attention to clean and environmentally friendly renewable resources. Among them, solar energy and geothermal energy are two renewable resources that are relatively easy to use. In the prior art, there are many heat pump systems that use solar energy and geothermal energy as energy sources. Due to the existence of two sets of energy supply channels during operation of this type of heat pump system, it is easy to cause fluctuations in operating pressure, resulting in inaccurate control of heat transfer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a solar ground source heat pump system and its control method, which can solve the def...
