Multi-energy adjustable and controllable energy supply system based on water circulation

Abstract

The invention discloses a multi-energy adjustable and controllable energy supply system based on water circulation. The multi-energy adjustable and controllable energy supply system comprises a solar water heat collector, a heat accumulation water tank, a water source heat pump outdoor side heat exchanger, an air source heat pump outdoor side heat exchanger, an air heat collector, a user side heat exchanger, an indoor heat exchanger and a gas boiler. According to the multi-energy adjustable and controllable energy supply system, a solar heat collector system is coupled with a heat pump system, a water source heat pump and an air source heat pump are used in parallel, and the gas boiler is used for auxiliary heating, so that the efficiency of the system is improved, the problem that solar energy is not stable is solved, and multi-condition running is achieved; and in addition, one set of system is adopted for heating and refrigerating, so that the structure is simple, and the manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the field of multi-energy utilization equipment, and more specifically relates to a multi-energy adjustable energy supply system based on water circulation. Background technique [0002] At present, the air-conditioning energy system is single and the efficiency is low. Two systems are required for heating in winter and cooling in summer, which is costly and not conducive to maintenance. In addition, the low efficiency of the central air-conditioning system is not conducive to environmental protection and energy saving. [0003] Solar energy is an environmentally friendly, safe, and non-polluting renewable energy, but solar energy is unstable, which limits its development. Solar water heaters are less efficient in low light conditions. If run into overcast and rainy for a long time or night, solar water heater will be unable to produce hot water, can not satisfy user's demand. At this time, electric heating assistance is requ...

Problems solved by technology

[0002] At present, the air-conditioning energy system is single and the efficiency is low. Two systems are needed for heating in winter and cooling in summer, which is costly and not conducive to maintenance. In addition, the low efficiency of the central air-conditioning system is not conducive to environmental protection and energy saving.

[0003] Solar energy is an environmentally friendly, safe, and non-polluting renewable energy, but solar energy is unstable, which limits its development

The efficiency of solar water heaters is low under the condition of low light

If there is a long period of rain or night, the solar water heater will not be able to produce hot water and cannot meet the needs of users

At this time, electric heating assistance is required, but this is contrary to its energy-saving concept
