Multi-source heat pump energy storage and supply system and control method

Abstract

The invention provides a multi-source heat pump energy storage and supply system and a control method, and relates to the technical field of energy storage and supply. The system comprises an energy storage unit, an AAHP unit, a water condenser heat exchange unit, an AWHP unit, an energy supply tail end and a controller. The condenser end of an outdoor unit of the AAHP unit is communicated with the heating end of the water condenser heat exchange unit; the water supply end of the water condenser heat exchange unit and the water supply end of the AWHP unit are communicated with the first watersupply end of the energy storage unit, and the first water return end of the energy storage unit is communicated with the water return end of the water condenser heat exchange unit and the water return end of the AWHP unit; the second water supply end of the energy storage unit is communicated with the water supply end of at least one energy supply tail end, and the water return end of at least one energy supply tail end is communicated with the second water return end of the energy storage unit; and the control end of the AAHP unit, the control end of the water condenser heat exchange unit, the control end of the AWHP unit and the control end of the energy storage unit are in communication connection with the controller. The operation cost can be guaranteed, and the energy supply effect is improved.

Description

technical field [0001] The present application relates to the technical field of energy storage and energy supply, in particular, to a multi-source heat pump energy storage energy supply system and a control method. Background technique [0002] With the continuous development of "clean heating" work, the "dual substitution" energy transformation is the focus, that is, the use of electricity to replace coal and gas to replace coal to gradually realize the substitution of coal. [0003] Among them, the coal-replacing electricity technology in clean heating mainly includes direct electric heating and heat pump systems. However, direct electric heating consumes a lot of electricity, and the cost of use is high; the heat pump system only consumes a small amount of electric energy to drive heat transfer from low to high, which is more than three times that of direct electric heating, which is the inevitable direction of electric heating . [0004] Although the heating efficienc...

However, direct electric heating consumes a lot of electricity, and the cost of use is high; the heat pump system only consumes a small amount of electric energy to drive heat transfer from low to high, which is more than three times that of direct electric heating, which is the inevitable direction of electric heating

[0004] Although the heating efficiency of the heat pump system has been greatly improved compared with direct electric heating, the energy supply operation cost of the whole system is still not to be underestimated, and the operation cost is still relatively high
