Solar-earth source heat pump seasonal balance heating system

Abstract

The invention discloses a solar energy-soil source heat pump seasonal balance heating system comprising a solar energy heat collector, a water tank and a solar energy heating heat-exchange coil pipe, wherein a ground source heat-pump heat-exchange coil pipe is arranged in the water tank and communicated with a plate heat exchanger by a second circulation pipeline; a second water pump, a second water pump, a first constant pressure tank and a magnetic valve are arranged on the second circulation pipeline; the plate heat exchanger is communicated with a heat pump assembly by a third circulation pipeline; a third water pump, a third constant pressure tank and a magnetic valve are arranged on the third circulation pipeline; the plate heat exchanger is communicated with an underground burying pipe by a fourth circulation pipeline; the underground burying pipe is buried underground and is provided with an underground insulating device; and a fourth water pump, a second constant pressure tank and a magnetic valve are arranged on the fourth circulation pipeline. The solar energy-soil source heat pump seasonal balance heating system can store redundant heat generated by a summer solar energy heat collecting system in winter to use, effectively save energy sources, increase the use efficiency of solar energy and solve the detects of the traditional earth source heat pump.

Description

technical field [0001] The invention relates to a heating system, in particular to a heating system combining a solar heat collection system and a ground source heat pump. Background technique [0002] Solar energy is an important renewable energy source. The current solar water heating system has been widely used in the supply of domestic hot water throughout the year. In order to greatly increase the amount of solar energy used to replace more conventional energy sources, the use of solar energy has gradually involved In the field of heating, but the solar energy systems used in some pilot projects are simply amplified domestic hot water systems, and there is a technical bottleneck of heat gain in summer and loss in winter. At the same time, ground source heat pump technology has been widely used in building heating in winter and air conditioning in summer, but in colder regions, it usually occurs that the amount of heat discharged to the ground during cooling in summer is...

[0002] Solar energy is an important renewable energy source. The current solar water heating system has been widely used in the supply of domestic hot water throughout the year. In order to greatly increase the amount of solar energy used to replace more conventional energy sources, the use of solar energy has gradually involved In the field of heating, but the solar energy systems used in some pilot projects are simply amplified domestic hot water systems, and there is a technical bottleneck of heat gain in summer and loss in winter. At the same time, ground source heat pump technology has been widely used in building heating in winter and air conditioning in summer, but in colder regions, it usually occurs that the amount of heat discharged to the ground during cooling in summer is less than the heat absorbed from the ground during heating in winter , long-term operation will bring the consequences of lower soil temperature and worse system operation effect
