Problems solved by technology

[0005] In the existing market, there are few mature energy storage devices, especially small civil energy storage devices, especially a kind of electric energy storage water heater and energy storage air source water heater combined with energy storage devices. The existing air source water heater Energy can only be stored in hot water. Hot water is a kind of sensible heat, and the energy storage is small. Therefore, it cannot make good use of the price advantage of valley electricity at night.

Abstract

The invention belongs to the field of household appliances and the energy saving technology, particularly relates to the technologies of an energy storage heat exchanger, an electric energy storage water heater and an energy storage air source water heater, provides an energy storage device which is reasonable in design, simple in structure and large in energy storage capacity, and particularly provides the energy storage heat exchanger, the electric energy storage water heater and the energy storage air source water heater. The energy storage device can be combined with the solar energy technology, combined with heating cables to form a pure electric energy storage water heater and combined with a heat pump to form the energy storage air source water heater. Therefore, by means of the water heaters, energy is saved, energy can be stored by means of off-peak electricity at night, and a prioritization scheme for peak load shifting in electricity usage is provided. Furthermore, the energy storage device can be used for storing cold or recovering waste heat of a traditional air conditioner condenser.

Description

technical field [0001] The invention belongs to the technical field of household appliances and energy saving, and in particular relates to the technology of an electric energy storage water heater and an energy storage air source 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 contin...
