Technical Field

The invention relates to the field of rural heating, in particular to a rural multifunctional heating kang system based on electric auxiliary heat and solar energy.

Background

Aiming at heating in rural areas in northern China, a coal-fired heating system with serious pollution is still the most important heating mode in rural areas. In areas with low economic level, the traditional heating mode is adopted, so that the environment is polluted, and certain comfort level cannot be achieved. According to the regional characteristics, a specific heating mode is adopted according to local conditions, and the key point for solving the heating problem in rural areas is realized. The method actively promotes the development and utilization of clean energy, does not improve the heating cost, and is an effective strategy for promoting northern clean heating engineering.

At present, aiming at remote rural areas, the mainstream heating mode is as follows: a smoke stove, a coal stove, a traditional kang, a cooking bench, an electric blanket, a boiler water heating mattress and the like. These heating methods have many drawbacks, such as: the furnace generally radiates heat generated by coal combustion to the indoor through a furnace body, and the heat is transferred to the indoor through a chimney in the process of discharging smoke to the outdoor; although the mode is cheaper, the smoke is directly discharged to the outdoor, the pollution to the environment is serious, and the indoor air is ensured to be fresh by frequently opening windows for ventilation so as to avoid poisoning; combustible, flammable and explosive materials cannot be stored nearby the stove to avoid causing fire; the user is required to have higher awareness of safety and environmental protection. The traditional kang is connected with the ground, built by bricks and connected with a kitchen hearth; flue gas generated by cooking of farmers transfers heat to the kang body through the flue and then transfers the heat to the indoor; because only the surface heat dissipation of the kang leads to the room, the phenomenon that the heated room of the kang is cold sometimes can appear in the interior uneven temperature, and the travelling comfort is not high. The electric blanket heating mode has potential safety hazards, electromagnetic radiation emitted by the electric blanket is easy to damage human bodies, aging and electric leakage are easy to occur after the electric blanket is used for a long time, and great potential safety hazards are brought.

Aiming at the traditional rural clean heating technology improved by the earthen bed and a lot of researches on utilizing solar energy coupling, for example, a solar energy electric heating bed method (authorization notice number: CN 204950187U) is designed in the published patent of a solar energy electric heating bed method, a solar energy power generation system is utilized to supply power, and a carbon fiber electric heating plate is utilized to heat and heat. In the published patent of an earthen bed with heating (application publication No. CN 103388853A), part of the wall is designed as steel plates aiming at the traditional earthen bed, so that the good heat conductivity of the steel plates is utilized to transfer the heat in the bed to the indoor space, thereby playing the role of heating. The disclosed patent of a balcony solar phase-change heat-storage warm bed device (with the publication number of CN 206062668U) introduces the concept of a heat-storage warm bed, thereby improving the use comfort, and simultaneously has the function of a radiator, can radiate heat indoors, adopts renewable energy solar energy as a heat source, and is more environment-friendly. However, these studies: although solar energy is utilized, photovoltaic power generation is mainly utilized, the basic principle is electric heating, and the economy and the safety are not high; the heated brick bed has the function of heating indoors, but the process is complex, the investment cost of a user is increased, and the popularization is difficult.

In conclusion, the problems of high energy consumption and poor safety in the process of using the bed warming equipment are difficult to effectively solve in the prior art. The technology comprehensively considers the heating economy, fully utilizes the solar thermal resources and improves the indoor thermal comfort level in rural areas is very important.
