Background
Heating in winter in northern areas of China is an important civil engineering. Wherein, most of heating in cities and towns adopts a central heating mode, but in areas where a heat supply network cannot be accessed, people still use coal and straws as main fuels for heating. Materials are also available in forest areas, and the situation that branches, trunks and the like are used as heating fuels appears, so that the labor intensity of people is greatly increased, the damage to the environment is aggravated, and the atmospheric pollution is aggravated.
In order to reduce environmental pollution and implement clean heating in winter, a policy of encouraging the peak-valley flat electricity price of 'coal-to-electricity' is issued from place to place successively. For example, when electricity price of certain electricity-saving heating reaches the home, the electricity price is respectively executed according to 0.645 yuan/kWh, 0.513 yuan/kWh in the ordinary time period and 0.2898 yuan/kWh in the valley time period, wherein the electricity price is 8 hours (7:00-11:30/17:00-20:30), 6 hours (6:30-7:00/11:30-17:00) in the ordinary time period, and 10 hours (6: 30-the next day, 6:30) in the valley time period.
At present, the users using the electric heating mode mostly utilize the policy advantage of peak-valley flat electricity price to control the heating time interval of the electric boiler. That is, at the time of the valley price, the heat medium, for example, a liquid such as water, in the heat storage tank is heated in advance. And stopping heating at the peak electricity price time period, circulating the heating medium in the heat storage tank, and releasing heat to the indoor space through a heating radiator, a floor heating system and the like to achieve the purpose of heating.
In order to ensure the continuous operation of a heating period system, when equipment fails, the heat medium in a tank is discharged so as not to cause long-time heating interruption or damage to a heating pipeline and other accidents, and the conventional heat storage type electric boiler heating system mostly adopts a design mode that a heating unit (such as a host) is separated from a heat storage tank. After being heated by the heating unit, a heating medium (such as tap water or return water) is injected into the heat storage tank through the circulating pipe network. In general, in order to make the temperature of water in the heat storage tank higher, the heat medium in the heat storage tank is heated in a plurality of cycles. This results in a heating system having a plurality of parts such as a heating unit, a heating medium circulation unit, a heat storage tank, and related connecting lines in addition to a heat radiation unit such as a radiator. The workload during system installation and later maintenance is increased, waste on the site is caused for users, and heating cost of the users is increased in a phase-changing manner.
In addition, in addition to the heating system of the larger heat storage type electric boiler, some heat storage tanks with smaller volume usually have heating units placed at the bottom of the heat storage tanks to reduce the occupied space and the production cost. In case of the structure, once the electric heating unit is damaged and parts need to be repaired and replaced, all water in the tank needs to be discharged, otherwise, the operation cannot be carried out.
Therefore, a new technical solution is needed to solve the above technical problems.
