Description

Photoelectric complementary heating system

Technical Field: The utility model relates to a heating system, in particular to a heating system which utilizes solar energy and electric energy to compensate each other to obtain heating and hot water sources.

Background technology: The heat source of the commonly used heating system is a single coal-fired, oil-fired, gas-fired boiler and electric boiler, which consumes a lot of energy and costs high. And the massive use of conventional energy will inevitably pollute the environment. With the development of the national economy, the demand for energy is increasing day by day, and the situation of energy utilization is tense. There are heating systems using solar energy as a heat source in the market. As a renewable energy source, solar energy is inexhaustible and inexhaustible, which is harmful to the environment. No pollution, using solar energy to meet domestic hot water and heating has a huge energy-saving effect. Therefore, solar heating technology is more and more subject to people's attention. However, solar heating is greatly affected by the weather, and the heating guarantee rate is low, which cannot fully meet people's heating needs.

Summary of the invention: The utility model aims at the above existing problems and provides a photoelectric complementary heating system, which uses solar energy as the main heat source and electric energy as the auxiliary heat source for the loss and shortage of solar energy, so as to overcome the inability of a single solar energy to guarantee a 100% supply rate and Disadvantages such as high electric energy heating costs.

The technical scheme of the utility model is as follows: it includes a solar water heater composed of an exhaust valve, a solar heat collector, a shower, a stop valve, a check valve and inlet and outlet pipes, and also includes an electric boiler, a circulating pump , cut-off valve, radiator, check valve and connecting pipes form an electric heating system. It is to install an insulated water tank on the outlet pipe of the solar water heater, and connect it to the inlet pipe of the electric boiler through the insulated water tank. At the same time, the return pipe is connected to the solar water heater. Water connection.

The utility model has the following advantages and positive effects:

1. The heating system organically combines the electric heating system with the solar water heater, uses solar energy as the main heat source, and uses electric energy as the supplementary heat source of solar energy for heating, which not only saves a lot of heating energy consumption and costs, but also improves the reliability of heating. Make up for the lack of a single heating method;

2. The heating system uses clean energy, which avoids air and environment pollution from coal-fired and oil-fired boilers, and truly achieves the best effect of environmental protection, energy saving and emission reduction.

3. The heating system uses the temperature control device of the electric boiler itself to automatically control the opening or closing of the electric boiler and the circulating water pump through the difference between the outlet water temperature of the insulation water tank and the preset heating water temperature and the difference between the actual room temperature and the set room temperature, and accurately selects the heating The gear position can reliably realize the equivalent pre-value electric compensation, and obtain energy-saving, high-efficiency, economical and practical operation effects.

4. The heating system uses the heat preservation water tank to store solar energy to make up for the lack of day and night, and fully utilizes solar energy to increase the supply rate. It not only prolongs the heating and water supply time, but also effectively increases the boiler inlet water temperature, reduces the power-on time and input power of the electric boiler, reduces the operating cost, and realizes the economic effect of energy saving and consumption reduction.

5. The heating system can be used for both heating and bathing, and it is the best heating solution for high efficiency, energy saving, emission reduction, and resource environment protection. It also has reasonable structural design, convenient and flexible use, stable and reliable performance, safe and efficient operation, and is suitable for industry promotion, etc. advantage.

Description of drawings: Figure 1 is a structural diagram of a photoelectric complementary heating system.

Specific implementation: The photoelectric complementary heating system shown in Figure 1 is an energy-saving and efficient heating system designed on the basis of existing technologies. It retains the electric boiler 7, cold and hot water circulation pumps 8, 9, cooling , hot water cut-off valves 10, 11, radiator 12, check valve 13 and the electric heating system formed by connecting pipes, and simultaneously utilize exhaust valve 1, solar heat collector 2, and shower 3, stop valve 4, The solar water heater composed of the check valve 5 and the water inlet and outlet pipes is provided with an insulated water tank 6 on the outlet pipe of the heat collector 2 of the solar water heater, and is connected with the water inlet pipe of the electric boiler 7 through the insulated water tank 6, and the return pipe is connected through the reverse The stop valve 13 is connected with the solar water heater inlet pipe.

The water supply of the heating system can be connected by tap water pipe network or other water inlet pipe network. After the water is heated by the solar collector 2 and the electric boiler 7, it is supplied to the radiator 12 for heating and bathing. 8,9 make the water circulate in the whole system. The utility model is characterized in that it not only uses the heat preservation water tank 6 to store solar energy to supplement the lost source, but also uses the temperature control device of the electric boiler itself to automatically control the temperature difference between the water outlet temperature of the heat preservation water tank and the preset heating water temperature and the difference between the actual room temperature and the set room temperature The electric boiler and circulating water pump are turned on or off, and the heating gear is accurately selected to automatically realize photoelectric complementarity to ensure a 100% supply rate.
