Dual-cavity type electric energy storage heating system

Abstract

The invention relates to a dual-cavity type electric energy storage heating system. The dual-cavity type electric energy storage heating system comprises a box body shell with a control panel, a heatstorage furnace outer container is arranged inside the box body shell, a heat storage furnace inner container is arranged inside the heat storage furnace outer container, and a hollow layer is formedbetween the heat storage furnace outer container and the heat storage furnace inner container; a heat storage furnace, reflective plates, a heat storage medium with a heat-conducting structure and electrical heated tubes are correspondingly arranged from top to bottom inside the heat storage furnace outer container, a heat-absorbing coating and a reflective coating are applied on the left and right plate surfaces at the bottom of the reflective plates correspondingly, the reflective plates are linearly displaced by a sprocket drive mechanism controlled by a motor, so that the size of a heat release area at the top of the heat storage furnace can be controlled; oil transporting fin tubes are arranged in the heat storage furnace and are distributed in a waveform. According to the dual-cavitytype electric energy storage heating system, low valley power is fully utilized to heat the heat storage medium through the electrical heated tubes at night; during peak hours of electricity use in the daytime, the heat storage medium is used as a heat source to continuously provide indoor heat; and the cost can be saved by 29.6% compared to 24 hours of continuous heating by using the dual-cavitytype electric energy storage heating system.

Description

technical field [0001] The invention relates to the field of electrothermal equipment, in particular to a dual-cavity electric energy storage heating system integrating heat storage and heat utilization during electrothermal conversion. Background technique [0002] With the increasing demand for electricity, the peak-to-valley load difference of the power grid is also becoming more and more significant, which leads to a power gap during the peak of the daytime power consumption, and some power is wasted at night. This load difference is simply to increase the installed capacity. unsolvable. [0003] At present, electric energy storage heating technology has many shortcomings, which are manifested in the following aspects: 1. The heat storage temperature is low, and the heat storage capacity is small; 2. The heat preservation effect is poor, the heat loss is large, and the thermal efficiency is low; 3. There are serious problems. 4. The maintenance of vulnerable parts (such...
