Abstract

The embodiment of the invention provides a multi-source heat supply electric heat storage warm air supply device, and relates to the technical field of heat energy. The device comprises a heat preservation cavity, a steam compression type heat pump, a low-grade heat collector, a 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 heating element conducts heating in the off-peak electricity stage and stops heating in the peak electricity stage, and the heat preservation cavity is provided with an air inlet and an air outlet. The steam compression type heat pump is installed at the air inlet, the low-grade heat collector is installed outside the heat preservation cavity, the heat exchanger is connected with the low-grade heat collector and installed in the heat preservation cavity, and external air passes through a condenser, then passes through the heat storage medium and the heat exchanger and finally is exhausted from the air outlet. According to the multi-source heat supply electric heat storage warm air supply device, the steam compression type heat pump is installed at the air inlet, the low-grade heat collector continuously operates to collect heat, electricity consumption is reduced, the gradient utilization of heat energy is achieved, and the electric heating effect is improved.

Description

technical field [0001] The invention relates to the technical field of heat energy, in particular to an electric heat storage warm air supply device for multi-source heat supply. 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 the cold winter, hot air heating is required indoors; for industria...
