Solar energy-storage hot water heat-supply system

Abstract

The present invention relates to a solar energy-storing hot water heating system, especially is suitable for the heating system of towns and villages residential buildings in China's severe cold or cold areas. The solar energy-storing hot water heating system described in the invention includes solar energy heat collector, antifreeze water tank, antifreeze water tank cut-off valve, solar energy heat-storing water tank, circulating water pump and circulating water pump cut-off valve which are connected sequentially and form circuit. The solar energy-storing hot water heating system provided in the invention combines the solar energy heating and traditional heated brick bed heating organically, fully shows the advantages of traditional heated brick bed heating, compared with prior system, the water supply temperature of hot water heating system is reduced, it reduces the heat loss of heat collector and increases the utilization efficiency of solar heat collectors; the heat-storing water tank also can be used as indoor radiator, and can reduce the energy consumption of secondary cycle water pump and the accommodation area of heat-storing water tank; the organic combination of traditional heated brick bed can use smoke gas residual heat effectively, reduce conventional energy consumption, at the same time, it is fit the users residents lifestyle in northern region.

Description

Technical field [0001] The invention relates to a solar energy storage hot water heating system, which is particularly suitable for a heating system used in residential houses in villages and towns in severe cold or cold areas in my country. Background technique [0002] Solar low-temperature hot water residential utilization technology is currently mainly used for domestic hot water supply in summer and auxiliary heating in winter, which is to reduce energy consumption and reduce CO 2 An effective means of emissions. At present, solar hot water heating systems are mostly composed of solar collectors, hot water storage tanks, heat exchange equipment, circulating water pumps and heat dissipation equipment. When using solar energy for heating, due to the periodic fluctuation and uncertainty of solar radiation, in order to achieve a comfortable indoor temperature, it is often necessary to install a hot water storage tank, add a circulating water pump, and use the water pump to drive...

Problems solved by technology

Due to the periodic fluctuation and uncertainty of solar radiation when using solar energy for heating, in order to achieve a comfortable indoor temperature, it is often necessary to install a heat storage tank, add a circulating water pump, and use the water pump to drive the water between the indoor radiator and the heat storage tank. System circulation, in this way, the water pump will be in a state of all-weather operation, the power consumption of the water pump is high, and the requirement for water temperature is high when the radiator is used to dissipate heat, resulting in a reduction in solar heating efficiency and shortening of heating time, while storing hot water Box setup also increases footprint

[0003] In the rural areas of northern my country, heated kang heating is often used for heating. Over the years, a lifestyle centered on kang has gradually formed. The heated kang heating method makes full use of the waste heat of stove combustion and has the characteristics of low cost. Currently, it is widely used The solar heating system cannot use the waste heat from the stove, which not only causes a waste of energy, but also affects the living habits that people have developed over the years.
