Problems solved by technology

For example, natural gas is used for heating in winter in northern regions, and a heating season requires about 136.9 billion cubic meters of gas. In addition, gas-fired boilers emit emissions per unit of heat supply. The combination of nitrogen oxides and fine dust in the air is an important factor for the formation of smog. One of the factors is that if a large amount of natural gas is burned, the degree of smog will increase. In view of this, it is not suitable and cannot use natural gas for heating on a large scale in our country
If heating with electricity, there are two problems to be solved. One is the load problem. The original peak power consumption plus the heating load will make the peak load even higher, and winter is the trough period of hydropower. Therefore, the power grid backup is proposed. Higher requirements, the second is the high cost of electricity, and it is difficult for many families to bear it

Embodiment

[0024] Electric heat storage heating system such as figure 1 As shown, the system is composed of an electric heater 5, an upper water tank 1, a lower water tank 4, a valve 2, a radiator 3, a circulating water pump 7, a controller 6, water supply and return pipes, etc., and the upper water tank 1 is a heat storage tank. When running, choose low power consumption to start, first fill the lower water tank 4 with water, then turn on the circulating water pump 7, turn on the heater 8, open the valve 2, hot water flows to the radiator 3, and heats the required space through the radiator 3 , the water temperature drops after passing through the radiator 3, and flows back to the lower water tank 4. During this process, it is necessary to ensure that the amount of water flowing into the upper water tank 1 is greater than the amount of water flowing out of the upper water tank 1, so that the upper water tank 1 can store enough electricity for peak use. The hot water, when the power cons...

Abstract

The invention relates to an electric thermal storage type heating system. The heating system comprises an upper water tank (1), a lower water tank (4), a valve (2), a radiator (3), a circulating waterpump (7) and a controller (6); the upper water tank (1) is higher than the lower water tank (4) and is internally provided with an electric heater (5), an outlet of the upper water tank (1) is connected to an inlet of the valve (2), an outlet of the valve (2) is connected to the radiator (3), an outlet of the radiator (3) is connected to an inlet of the lower water tank (4), an outlet of the lower water tank (4) is connected to an inlet of the upper water tank (1) through the circulating water pump (7), and the controller (6) is connected to the circulating water pump (7). Compared with the prior art, the heating system has the advantages that the problem of high power grid loads during a peak period of power consumption can be solved, and electric bills are reduced for residents.

Description

technical field [0001] The invention relates to a heating system, in particular to an electric heat storage heating system. Background technique [0002] In my country, there are mainly three kinds of energy sources for heating in winter, coal, natural gas and electricity, among which coal is the main energy source. 100 million tons of standard coal, of which about 200 million tons of coal are scattered-fired (including coal for low-efficiency small boilers), mainly distributed in rural areas. This heating method has aggravated the haze weather in winter in the northern region. The natural gas heating area in northern my country is about 2.2 billion square meters, accounting for 11% of the total heating area; the electric heating area is about 400 million square meters, accounting for 2%. In order to control the heating pollution in winter and improve the energy structure, less coal is used and more natural gas or electricity is used. However, my country is a country that ...
