Abstract

The embodiment of the invention provides an electric heat storage device coupled with a heat energy driving type heat pump, and relates to the technical field of heat energy. The device comprises a heat preservation cavity, a heat energy driving type heat pump, a gas-liquid heat exchanger and a heat storage medium arranged in the heat preservation cavity, the heat storage medium is connected with external power supply equipment through a heating element, the gas-liquid heat exchanger is installed in the heat preservation cavity and communicated with an external liquid supply pipe, and the heat energy driving type heat pump is installed at an air outlet of the gas-liquid heat exchanger. The heat preservation cavity is a sealed cavity, and air in the heat preservation cavity circularly flows along the heat energy driving type heat pump, the heat storage medium and the gas-liquid heat exchanger in sequence. According to the electric heat storage device coupled with the heat energy driving type heat pump, the heat energy driving type heat pump is introduced into the electric heat storage device, the electricity consumption of the electric heat storage device is reduced, and the electricity consumption cost is reduced; the gradient utilization of heat is achieved, the utilization efficiency of heat is improved, and electric energy consumption is further reduced.

Description

technical field [0001] The invention relates to the technical field of heat energy, in particular to an electric heat storage device coupled with a heat energy-driven heat pump. Background technique [0002] With the rapid development of the power industry, more and more power station systems have emerged in China. During the low-peak period of electricity consumption, the load decreases, resulting in a large amount of surplus low-peak electricity. The characteristics of power products are that production, supply, and sales are completed at the same time. The large surplus of low-peak electricity leads to waste of power resources, which is not conducive to energy conservation and environmental protection. To this end, different electricity prices are used for low-peak electricity and peak electricity to urge people to stagger the use of electricity, improve energy utilization, and reduce waste. [0003] In cold winter and industrial production, hot water or hot oil is often...
