Energy storage electric water heater

Abstract

The invention discloses an energy storage electric water heater. The energy storage electric water heater comprises a liner, and an outer insulation cover for wrapping the liner; and a heat exchange pipe, an electric heating pipe, a temperature sensor, a phase change energy storage material and a heat conducting medium are arranged in the liner. The energy storage electric water heater is characterized in that an inner cavity of the liner is divided into two independent cavities by a separation plate; the two independent cavities consist of a storage cavity at the upper part, and a heating cavity at the bottom; the heat exchange pipe and the phase change energy storage material are arranged in the storage cavity; the electric heating pipe and the heat conducting medium are arranged in the heating cavity; a cold water inlet, a hot water outlet, a feeding port, a normal-pressure air port and an electric heating pipe joint are arranged on the outer insulation shell; the heat exchange pipe is connected as a whole in series or in parallel by multiple totally S-shaped sub heat exchange pipes; one ends of the sub heat exchange pipes are fixedly welded with the separation plate through heat conducting plates, so that the heat exchange pipe and the separation plate are connected as a whole through the heat conducting plates; preferably, a liquid level sensor is arranged on the normal-pressure air port; and meanwhile, an electric valve is arranged in the cold water inlet, and a layer of silicone oil covers the upper surface layer of the phase change energy storage material.

Description

technical field

[0001] The invention belongs to the technical field of electrical appliances, energy storage and energy saving, and in particular relates to a technology of an energy storage electric water heater. Background technique

[0002] With the improvement of people's living standards and the comfort requirements for working and living environments, the consumption of electric energy has increased significantly, resulting in excessive energy consumption, increased environmental pollution, excessive peak and valley loads on the power grid, and serious shortage of power supply during peak loads. Such as the increase of building energy consumption. At present, the building energy consumption in developed countries in Europe and the United States has reached 40% of the total energy consumption of the whole society. In my country, building energy consumption accounts for about 30% of the total energy consumption in the country. With the continuous development of the economy...
