Description

Solar heating boiler

(1) Technical field

The utility model relates to a solar heating equipment, in particular to a combination of a solar hot water system and traditional heating equipment.

(2) Background technology

As a clean energy source, solar energy has been widely used, but at present, its main application areas are mostly concentrated in solar power generation and domestic hot water supply. For the large energy-consuming area of heating in winter in the north, solar energy has not yet get involved.

Judging from the current heating methods in winter, it is mainly centralized heating and household heating. With the implementation of the national energy conservation and emission reduction policy and the reform of the heating mechanism, household heating occupies more and more market shares in the heating market. Based on the purpose of energy saving and emission reduction, among the current household heating equipment, the gas-fired wall-hung boiler heating system imported from Europe has the best effect and consumes less energy. Of course, energy saving and emission reduction are necessary for our big energy-consuming country. If gas-fired wall-hung boilers, which consume a lot of fossil fuels, are used, no matter from the perspective of energy consumption or the impact on the environment There are deficiencies.

In addition, solar energy is limited by seasons and weather factors. If the solar energy system is used alone as a heating device, there will be disadvantages of unstable or insufficient heating of the system. On the other hand, when solar energy is used as domestic water, there may be surplus heat collection when the sun is sufficient, and this surplus heat has not been fully utilized yet.

(3) Contents of the invention

The transition between the liquid pipe and the heat medium inlet pipe;

The second three-way solenoid valve, the three ports are respectively connected to the heat main pipe, the heat medium outlet pipe and the heat pipe for heating medium in the heating system, at least including controlling the on-off of the above-mentioned heat main pipe and the heat medium outlet pipe; and

Two temperature sensors, one of which is used to collect the lower limit of the temperature of the water tank, and its low temperature setting value triggers the communication between the heat main pipe and the heat medium outlet pipe, and triggers the first three-way solenoid valve to communicate with the heat medium inlet pipe through the liquid outlet pipe The state is converted to another state; the other is used to collect the upper limit of the temperature of the water tank, and its high temperature setting value triggers the first three-way solenoid valve to switch from the state in which the heat main pipe is connected to the liquid outlet pipe to another state.

In the above solar heating boiler, the temperature sensor for detecting low temperature is located at the bottom of the water tank, and the temperature sensor for detecting high temperature is located at the top of the water tank.

In the above solar heating boiler, the domestic water pipe is located at the upper part of the water tank, and the water source pipe is located at the lower part of the water tank.

In the above solar heating boiler, a hole is opened on the top of the cabinet for passing through the exhaust pipe of the gas boiler, and a hole is opened on the back or on the top for external pipelines.

The utility model integrates the solar heat collection system and the gas boiler heating system together. When the temperature of domestic water is low, the gas boiler is incorporated into the solar heat collection system to obtain domestic hot water at a suitable temperature; When high, solar thermal systems are incorporated into the heating system to reduce the use of fossil fuels. The two systems complement each other to achieve suitable living needs and reduce the use of fossil fuels.

The realization of the above-mentioned functions is automatically controlled by using the temperature sensor and the solenoid valve, but the increase cost is not high for the two systems. On the other hand, we know that if solar energy alone is added to an auxiliary heating device such as electric heating, it will not only increase the cost, but also the electric heating device must be installed in the water tank to directly heat domestic hot water, resulting in a large amount of fouling and electric heating The heating device has a certain risk of electric shock; in addition, the system based on the utility model can also use the surplus heat of solar energy for the heating system, and its overall cost can be greatly reduced relatively.

Under normal circumstances, the gas boiler can basically meet the heating requirements when it is turned on for 4 to 5 hours a day. Of course, the current gas boiler heating system has its own automatic control system, which can meet the automatic control. The above-mentioned temperature sensor and solenoid valve or required input and output control points can be easily incorporated into the above-mentioned automatic control system.
