Solar heating system

Abstract

The invention provides a solar heating system, which comprises a heating unit, a heat storage and exchange unit and a heat supply unit, wherein the heating unit is used for collecting solar energy and converting the solar energy into heat energy; the heat storage and exchange unit comprises an energy storage system and a heat pump system, wherein the heat storage system is used for storing heat energy in the heating unit, and the heat pump system is capable of increasing the temperature of the heat energy stored in the energy storage system; the heat storage system is arranged underground; and the heating unit, the energy system, the heat pump system and the heat supply unit are communicated in sequence for carrying out heat exchange. The solar combined heat supply system disclosed by the invention has the advantages of low cost, high efficiency, energy saving and practicability and is particularly suitable for small-range people colonies with harder conditions.

Description

technical field [0001] The invention belongs to the technical field of solar energy application, and relates to a solar heating system, which is especially suitable for using solar energy to heat buildings in small-scale crowd-inhabited areas. Background technique [0002] As a new energy source, solar energy has the characteristics of less pollution and large reserves compared with traditional energy sources. It is of great significance to solve the serious environmental pollution problems and the depletion of resources (especially petrochemical energy) in the world today. At the same time, in some sparsely populated or high-cold and high-altitude areas, the cost of laying and maintaining power grids and heating networks is quite high, so it is generally carried out by means of separate heating and heating in a small area, especially in some areas with abundant solar energy. Using solar energy can solve the heating and heating needs of this part of the population to a certa...

Problems solved by technology

[0003] However, there are some deficiencies in existing solar heating systems, which are mainly manifested in: first, the optimal heating time period is inconsistent with the heating time period: since solar energy is an irregular energy source, the heating effect is good in fine weather during the day, but The heating effect at night is not good or has almost no effect, and for users, the time period for urgent heating is more concentrated in the evening, especially in the cold winter; second, the auxiliary heating used in conjunction with the solar heating system High system cost, not environmentally friendly: During the period when the solar heating effect is not good, only the auxiliary heating and heating system can be used to maintain the needs of life, that is, other systems connected in parallel with the solar heating and heating system, such as using boilers to burn coal to heat heat However, if you rely solely on this auxiliary heating system for heating for a long time, it will consume more resources and the cost will be huge. In some poor areas, resources and costs will undoubtedly increase. It makes heating difficult to realize, and boilers and other equipment will also pollute the environment due to the carbon dioxide emissions produced by burning coal; third, there is a limit to the distance of heating and heating: when using solar energy for direct heating and heating, when the heating When the distance between the source and the building to be heated is long, when the heat energy is input into the building where people work or live through the pipeline, it is generally impossible to continuously guarantee the hot water temperature of 80-90°C, but only Meet the usual domestic hot water needs, such as water temperature for washing
