Dual-energythermal storage heater for solar energy and using method thereof

Abstract

The invention relates to a dual-energy thermal storage heater for solar energy and a using method thereof. Asolar energy thermal collector receives irradiation of sunlight, when the thermal-conductingoil temperature of a negative camberflow channel inside a vacuum tube of the solar energy thermal collector minus the temperature of thermal-conducting oil inside a jacket thermal conducting oil tankequals the temperature which is greater than or equal to 7 DEG C, a thermal-collecting recycling pump is started, the thermal-conducting oil with a high temperature in the solar energy thermal collectoris ejected into the jacket thermal conducting oil tank to transmit heat of solar energy to the inside of the jacket thermal conducting oil tank back and forth, heat dissipationand heat supplying are realized, phase change materials inside an inner container are heated at the same time and store heat, while the sun dose not shine well or there is no sun at night, heat dissipation and heat supplying are realized by using the heat stored by the phase change materials, and when temperature in the jacket thermal conducting oil tank is less than 40 DEG C, an electric heating tube starts heating,and heat dissipationand heat supplying are achieved. The dual-energy thermal storage heater for solar energy can supply heat through solar energy when the weather is normal andcan make heat stored bythe phase change materials in advance continue to provide a heat source and supply heat when weather is not well or at night, and electrical heating is taken as auxiliary electric energy to provide aheat source while weather is not well.

Description

technical field [0001] The invention relates to a dual-energy heat storage heater for solar energy and a use method thereof, which are used for indoor heating. Background technique [0002] At present, the main way of heating in winter in northern my country is to use coal or natural gas or electricity to obtain heat for heating. Burning coal for heating is not environmentally friendly and is not conducive to the conservation of limited natural resources. The use of natural gas also results in a certain amount of energy consumption. In the electric heating mode, when the consumption of electric energy enters the peak period during the day, it will increase the burden on the power grid. [0003] Solar energy is an ideal energy that is inexhaustible and inexhaustible. How to use solar energy for heating has always been a subject of research and development by various enterprises. Because solar energy is greatly affected by seasons and weather, and the heat flux density is lo...

AI Technical Summary

Problems solved by technology

[0006] 1. The oil guide pipe is set in the inner tank. The oil circulation is to heat the oil guide pipe through the electric heating tube and circulate the oil in it. The natural circulation of this oil is very slow, which will cause low heat transfer efficiency

[0007] 2. Most of the phase change materials have corrosive substances, and the inner tank is not treated with anticorrosion, which will affect the service life of the inner tank

[0008] 3. The heat dissipation pipe is a straight-through heat dissipation pipe. The heat absorption and heat dissipation area of ​​the straight-through heat dissipation pipe is limited, and the heat absorption and heat dissipation effect is poor.

[0009] 4. The equipment is bulky and inconvenient to use
