Novel electric thermal storage system

Abstract

The invention discloses a novel electric thermal storage system which comprises a thermal storage device, heaters, an inner circulating system and an outer circulating system, wherein the outer circulating system is composed of a user system; the user system is composed of a radiator and a water faucet; the water faucet is a single-handle and double-valve combination type water faucet; the sizes and the movement conditions of two valves are completely consistent; a valve inlet of the water faucet is connected to an external pipeline; a valve outlet of the water faucet is a water fetching hole; the other valve inlet of the water faucet is connected to a water supply pipeline; and the other valve outlet of the water faucet is connected between the radiator and an outer circulating water pump. According to the novel electric thermal storage system, the system structure is optimized by adopting the unique design of the user system, the infrared radiation type heaters, a full-automatic controlled intelligent controller and the like and with high-density iron-based alloy as a thermal storage material, a user can freely switch functions of warming and removing hot water, and the novel electric thermal storage system is small in occupying area, high in thermal efficiency, convenient in operation, stable in performance, high in safety and low in running cost and is suitable for wide popularization.

Description

technical field [0001] The invention relates to the field of heat storage systems, in particular to a novel electric heat storage system. Background technique [0002] The use of clean energy for heating and hot water supply is an important aspect of improving the urban atmospheric environment and reducing pollution. At present, coal-fired boilers are generally used as heating boilers in cities in our country, which cause extremely serious air pollution. However, although the use of fuel oil, gas or general electric heating boilers can reduce the degree of air pollution, the operating cost of heating alone is relatively high, so it is not suitable for popularization and use. In recent years, my country's daytime electricity consumption has increased year by year, increasing the peak-to-valley electricity difference. In order to reduce the peak-to-valley power difference, the power management department has formulated a preferential policy for using valley power to reduce t...

Problems solved by technology

At present, domestic energy storage electric boilers mainly include atmospheric water tank split energy storage electric boilers, pressurized water tank energy storage electric boilers, electric heaters with iron oxide-based solids as heat storage materials, and solid-liquid phase change materials. It is an energy storage device for energy storage materials, but because of the small heat capacity of atmospheric water and pressurized water, a large water tank is required, the strength of the iron oxide-based solid is poor, the solid-liquid phase change material is expensive, the long-term performance is unstable, and some have Strong corrosiveness, etc., these devices cannot meet the practical application; moreover, the traditional heat storage system cannot satisfy the user's free switching between heating and hot water
