A combined heating system of solar energy and condensing gas wall-hung boiler

Abstract

The invention discloses a combined heating system using solar energy and a condensed fuel gas wall-hung stove. The combined heating system using solar energy and the condensed fuel gas wall-hung stove comprises (1) a solar heat collector which is mounted on a roof and facing to sunlight, (2) a heat storage tank, (3) the condensed fuel gas wall-hung stove, (4) a heating coil and (5) a climate compensator. The combined heating system has the advantages as follows: (1) the combined heating system uses solar energy as a primary heating source and uses fuel gas as auxiliary energy, and so that the combined heating system can effectively reduce the consumption of fossil energy, reduce the emission of environmental pollutants and optimize the utilization efficiency of the energy; (2) the combined heating system can overcome the defect that the fuel gas or the solar energy is used as a single heating source, so that the heating system is more reliable and stable and the application range of the system is expanded; (3) the combined heating system uses the solar energy as the solar heating source, so that the consumption of the fuel gas is can reduced, and thus the heating cost is reduced and an economical aim is achieved.

Description

technical field [0001] The invention relates to a heating system, in particular to a combined heating system of solar energy and condensing gas wall-hung boiler. Background technique [0002] With the rapid development of my country's economy and the increasingly serious problems of energy shortage and environmental pollution, energy conservation, emission reduction and low-carbon life have become the development trend of all walks of life. my country is rich in solar energy resources, and the total annual solar radiation of more than two-thirds of the country's land area exceeds 5.0GJ / m 2 , the annual average sunshine hours are more than 2200 hours. Especially in the vast North China and Northwest China, there is sufficient sunshine, which provides good natural conditions for the development and utilization of solar energy. Natural gas is a clean fossil fuel that has become the fastest growing energy source in the world. With the rapid development of China's economy and ...

Patent 200720019424.8, solar hot water is directly used for heating, which is prone to pollution. In winter, pipes are prone to freezing and cracking. Patent 200820103475.3. Patent 200820201588.7 domestic hot water and heating hot water are not separated, and solar hot water directly enters heating and domestic hot water, which is prone to pollution, and solar preheated hot water enters gas wall-hung boilers, which is prone to scaling and blockage; patent 200910062283.1 domestic hot water and The heating and hot water are not separated. When heating and hot water are needed at the same time, conflicts arise, and when the water is insufficient, water needs to be replenished, which affects the stability of heating. In addition, the temperature of domestic hot water is set too high, and the heating water supply is set at 40°C, which does not make full use of solar energy. This patent uses a water mixing device, which occupies a certain amount of indoor space; the heat storage tank in patent 201020129575.0 uses multiple heat exchangers, which reduces the heat exchange efficiency and does not make full use of solar energy; patent 201020243754.7 may have up to The use temperature of domestic hot water is lower than the use temperature of domestic hot water, and it will absorb part of the heat of heating water, which is not conducive to stable heating; patent 201120232330. Utilize solar energy; patent 201210330458.4 Domestic hot water and heating hot water are not used separately, and the heating temperature is set too high to make full use of solar energy
