Adaptive-with-wind load power type off-grid wind power heat storage and heating system for rural residences

Abstract

The invention belongs to the field of heat energy and utilization thereof, and discloses an adaptive-with-wind load power type off-grid wind power heat storage and heating system for rural residences. The adaptive-with-wind load power type off-grid wind power heat storage and heating system for rural residences is structurally characterized in that output ends of a wind driven generator (1) and a wind speed sensor (5) are connected with an input end of a wind-following type load power regulating device (6), an output end of the wind-following type load power regulating device (6) is connected with a heating element (4) of an indoor heat storage and heating conversion device, and a switch controller (2) is connected with a 220V domestic power source (3). The adaptive-with-wind load power type off-grid wind power heat storage and heating system is a distributive wind power heat storage and heating system provided for northern rural residents and is free of pollution, low in cost and wide in application range. Further, the system is capable of making full use of wind power which is a non-pollution renewable resource, and has the remarkable advantages of convenience, energy saving, environment friendliness and emission reduction.

Description

technical field [0001] The invention relates to an off-grid rural residential wind power heat storage and heating system whose load power adapts to the wind. It is an energy-saving and emission-reducing heating system using wind energy for heat storage and heating, and belongs to the field of heat energy and its utilization. Background technique [0002] At present, there are mainly the following types of heating methods at home and abroad in terms of heating equipment and facilities: one is central heating. This is a relatively traditional heating method, which is mainly divided into municipal heat pipe network and boiler centralized heating in the community. The second is the decentralized heating method: that is, each household independently forms a heating system. The third is the inverter air conditioner, heating in winter and cooling in summer. The fourth is the water source central air-conditioning system, also known as the ground source heat pump, which utilizes gr...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned heating methods have the following problems: ①Because there are no valves and heat meters for household metering in many residential buildings, residents cannot adjust the required heat according to their own needs.

②Decentralized heating and inverter air conditioners can flexibly adjust the heating time and temperature according to their own needs, but their cost is very expensive, and air pollution is also an important problem that must be faced

③Water source central air conditioning, also known as ground source heat pump, is an energy-saving and environmentally friendly heating method, but it is severely restricted by groundwater

In short, the above-mentioned heating methods all have the disadvantages of using traditional energy sources such as high carbon emissions, large consumption, and lack of energy conservation, which do not meet the national policy requirements of low-carbon environmental protection, energy conservation and emission reduction.

[0004] In addition, the traditional wind energy heating system also has the following problems. It stores wind energy in the battery, and then converts the DC power in the battery into AC power with a voltage of 220V and a frequency of 50Hz through an inverter to supply power for heating equipment.

But the problem is that the saturation problem of the battery and the secondary pollution problem not only waste energy, but also cause serious pollution to the environment

On the other hand, when the wind turbine has a fixed load, the generator can output power effectively only when the output power of the generator matches the power of the load. When the output power of the generator is less than the power of the load in the breeze phase, the generator can be wrapped and stopped. Rotation seriously affects the effective use of wind energy
