Double-source heat pump heat supply system

Abstract

The invention relates to the technical field of heat pump heat supply, in particular to a double-source heat pump heat supply system which comprises a heat pump host, a heat pump heat pump, a heat pump heat pump, a heat pump heat pump and a heat pump heat pump, the auxiliary heat source is circularly communicated with the energy storage equipment; and the energy storage circulating pipeline is communicated with the second circulating pipeline in parallel, and the energy storage equipment is installed in the energy storage circulating pipeline. According to the double-source heat pump heat supply system, an energy storage device does not need to be additionally arranged, the output mode of the double-source heat pump heat supply system can be adjusted according to the heat use requirement of a user side while the double-source heat pump heat supply system operates in a high-efficiency interval only by additionally arranging the energy storage circulating pipeline, and redundant heat can be stored in the energy storage equipment for use in the energy use peak period. The defects that the heat pump unit is insufficient in output power in the peak period of energy consumption and excessive in output power in the valley period of energy consumption are effectively overcome, heat can be fully utilized, and energy waste of the double-source heat pump heat supply system is reduced.

Description

technical field [0001] The invention relates to the technical field of heat pump heating, in particular to a dual-source heat pump heating system. Background technique [0002] Heat pump technology is a technology that transfers heat from a low heat source to a high heat source under the impetus of high potential energy. That is to say, it is a technology that converts low-grade heat sources that cannot be directly used, such as air, soil, water, solar energy, industrial waste heat, etc., into usable high-level energy heat sources, so as to partially save one-time energy. [0003] The difference between the dual-source heat pump and the ordinary heat pump is that the same unit can use either water source or air source as heat source. When the dual-source heat pump in the prior art is in operation, the heat energy collected by the solar energy is stored by the heat storage device as water source heat energy for use, and when the solar energy is insufficient, it is converted ...
