Description
Technical Field

Background
In recent years, due to the requirement of environmental protection, heating energy in many places in the north of China has gone on the way of reforming coal-to-natural gas, but due to the problems of short time, heavy task, insufficient natural gas storage capacity in China and the like, the phenomena of serious shortage of heating energy and suffering of residents from stopping heating occur in many places. In order to solve the problems of winter heating and the shortage of non-renewable energy sources, a mature novel renewable clean energy source is urgently needed to be found, and the system comprises the collection, storage and utilization of new energy sources and is a complete and rigorous system.
The popular small household solar water heater system and other similar solar heat storage devices are used for short-term heat storage of solar heat supply. Due to the characteristics of low solar energy density on the earth surface, alternate change of seasons and day and night and the like, a short-term heat storage system for solar heat supply inevitably has great instability, so that the solar utilization efficiency is very low.
The superficial layer of the earth surface is a huge solar heat collector which is not limited by regions, resources and the like, and is really large in quantity, wide in range and ubiquitous. This near infinite renewable energy stored in the shallow layers of the earth's surface makes geothermal energy a form of clean renewable energy as well. The temperature of geothermal energy or ground surface shallow geothermal resources is relatively stable throughout the year, is higher than the ambient air temperature in winter and lower than the ambient air temperature in summer, and is a good heat pump heat source and air conditioning cold source, and the temperature characteristic enables the operating efficiency of a ground source heat pump to be 40% higher than that of a traditional air conditioning system, so that the energy is saved and the operating cost is saved by about 40%. In addition, the constant geothermal energy temperature ensures that the heat pump unit operates more reliably and stably and ensures the high efficiency and the economy of the system.
How to utilize solar energy accumulated on the superficial layer of the earth surface for heating becomes a problem at present.
Chinese patent CN109654581A discloses a compound heating system based on cross-season heat storage of a confined aquifer, which combines a cross-season heat storage heating technology with an underground aquifer recharging energy storage technology, applies an original aquifer which can not continuously mine underground water due to the reduction of underground water level as an energy storage device, and reconstructs an in-situ heat well into a heat storage well and a heat collection well; in non-heating seasons, the water is heated by energy provided by solar energy and other energy sources and then is fed back into the heat storage well, and heat preservation and storage are carried out by means of the characteristics of low flow rate and small heat loss of an underground aquifer; in the heating season, the stored hot water is extracted from the underground aquifer through the heat collecting well and is respectively conveyed to each heating user by the heating unit.
The heating system disclosed in this patent utilizes a heat storage well to provide heat, but in cold regions, the temperature of the water in the heat storage well is low, and the solar energy stored in the shallow ground surface is insufficient to provide adequate heating in winter, and needs to be combined with other renewable energy sources to heat cold water together to produce hot water sufficient to supply municipal heating pipes.
