Problems solved by technology

[0005] The first is the ground source heat pump. Its disadvantage is that due to the fluctuation of underground geothermal energy, the load imbalance may appear from time to time. In extremely cold weather, it is not as stable as the conventional municipal heat supply. The source heat pump systems are all assisted by gas or coal-fired boilers. This system not only increases the cost, but also has little advantage in operating costs compared with conventional municipal heating, and also increases the workload of operators.
[0006] The second is cold storage / heat storage technology: because the peak-to-valley difference in grid electricity prices is used to achieve the purpose of energy saving, although the technology itself does not reduce energy consumption, it will increase the amount of electricity used to varying degrees
[0007] The third is that there are actually many applications of photovoltaic power generation technology in buildings, but the scale is generally very small, which is far from the role of large-scale promotion and demonstration. The power generation of the power generation unit cannot meet the power demand of the building itself. At the same time, because the residents' electricity consumption is concentrated at night, and because the independent photovoltaic power generation system faces very complicated problems of connecting to the grid, it is generally impossible to integrate the power generated into the national grid. As a photovoltaic building relying on solar power generation, the storage of electricity must be considered. The existing electricity storage relies on storage batteries, and the cost of storage batteries is currently very high, resulting in a high cost of the entire photovoltaic system as a whole.
[0008] The fourth is solar heat collection technology: its disadvantage is that relying solely on solar water heaters to solve the problem of domestic hot water supply is subject to site problems, load imbalance problems, extreme weather supply problems, etc.) and cannot be adopted on a large scale

Abstract

The invention provides a combined type renewable building energy source supplying system. The combined type renewable building energy source supplying system comprises a heat pump unit, a cold / heat accumulation barrel, a photovoltaic power generation assembly which is connected with a photovoltaic inverter further connected with the heat pump unit, a domestic hot water plate type heat exchanger, an electric power storage device, a solar energy heat collection device which is connected with a solar energy heat collection plate type heat exchanger further connected with the cold / heat accumulation barrel and the domestic hot water plate type heat exchanger, and a heat pipe type ground heat exchanger which is connected with the heat pump unit and a transition season cold supply plate type heat exchanger respectively. The comprehensive renewable building energy source system in which a heating system, a refrigeration system, a domestic hot water supplying system, an illumination system and the like are fused and combined is formed by organically combining a cold / heat accumulation technology, a heat pump technology, and an electric power storage technology, and has the advantages of saving energy, along with high efficiency.

Description

technical field [0001] The invention relates to the field of building energy supply, in particular to an intelligent building energy supply system for scheduling energy supply according to different conditions. Background technique [0002] At present, building energy consumption has been ranked alongside industrial energy consumption and transportation energy consumption, and has become the three "big energy consumers" of energy consumption in my country. sharp upward trend. [0003] At present, among the 2 billion square meters of newly-added houses in my country every year, more than 99% of them are buildings with high energy consumption; while only 4% of the existing buildings of about 43 billion square meters have adopted energy-saving measures, and the heating energy consumption per unit building area is less than that of developed countries. More than 3 times that of new buildings. At present, my country is in the rapid development stage of industrialization and urban...
