Integrated system with solar energy and ground-source heat pump combined for complementary energy supply

Abstract

The invention relates to an integrated system with solar energy and a ground-source heat pump combined for complementary energy supply. The system comprises a flat-plate type solar thermal collector, a vertical U-shaped cluster buried pipe, an integrated control unit, a user need terminal and a ground-source heat pump unit, wherein the flat-plate type solar thermal collector is used for collecting the year-round solar energy and providing thermal energy; the vertical U-shaped cluster buried pipe is connected with the flat-plate type solar thermal collector and used for storing the solar energy to supply heat in winter; the integrated control unit is connected with the flat-plate type solar thermal collector and the vertical U-shaped cluster buried pipe correspondingly, the on-off of an upper valve of a pipeline and the start and stop of a water pump are controlled by a control module to switch into different operating modes; the user need terminal is connected with the integrated control unit; and the ground-source heat pump unit is connected with the control module, a heating water tank, the tail end of a fan coil and the vertical U-shaped cluster buried pipe correspondingly. Compared with the prior art, the system has the advantages of being high in energy efficiency, high in degree of internet of things, high in engineering interchangeability, more sound in function and the like.

Description

technical field [0001] The invention relates to the fields of new energy, heat supply and new rural construction, in particular to an integrated system of solar soil source heat pump combined with complementary energy supply. Background technique [0002] With the increasing shortage of non-renewable energy, the utilization of renewable energy has been widely concerned. Common single renewable energy utilization technologies, such as solar thermal utilization, solar photovoltaic power generation technology, wind power generation technology, biogas heating technology, shallow geothermal utilization technology, etc. Often have certain limitations. For example, in rainy and cloudy weather, the supply stability of solar thermal / photovoltaic technology cannot be guaranteed; wind power technology has the problem of grid-connected load mismatch. An effective solution is to develop complementary utilization systems of multiple renewable energy sources. [0003] Compared with urba...

AI Technical Summary

Problems solved by technology

The reason lies in the limitations of the single renewable energy utilization method itself, the backward economic level in rural areas, the lack of system operation and maintenance technology, and the lack of conditions for industrialized mass production of similar energy supply systems
