Embodiment 1

[0044] Such as figure 1 As shown, a gas boiler and solar hybrid energy heating system, including cold water tank 9, heat collector 1, hot water storage tank 2, floor heating system 6, water pump one 4, water pump two 7, electric valve three 10, electric valve four 11. Boiler gas heating system 13, domestic hot water supply system 17, and heat exchanger-5 with channel A and channel B;

[0045] Cold water tank 9, heat collector 1, hot water storage tank 2, water pump 1 4, channel A, water pump 2 7, domestic hot water supply system 17 are connected in sequence, and the pipeline from water pump 2 7 to domestic hot water supply system 17 Electric valve three 10 and electric valve four 11 are arranged in sequence;

[0046] The boiler gas heating system 13 includes a combustion chamber, and a flue heat recovery part 12 and a heating heating part 13 communicating with the combustion chamber. There is a heat-absorbing pipeline 2 1201 inside, one end of the heat-absorbing pipeline 120...

Embodiment 2

[0051] Such as figure 1 As shown, a gas boiler and solar energy mixed energy heating system, its structure is compared with embodiment 1, the difference is: it also includes a heat exchanger 2 14 with channel C and channel D, the circulation of the floor heating system 6 The water outlet, channel C, and one end of the heat-absorbing pipeline one 1301 are connected in sequence, and the water source, channel D, the electric valve three 10, the heat-absorbing pipeline two 1201 and the electric valve four 11 are connected in sequence.

[0052] In this embodiment, the waste heat of the floor heating system can heat domestic water, so that when the user activates the boiler gas heating system 13, the heat generated by it can be fully utilized, and the needs of floor heating and domestic water heating can be met at the same time.

Embodiment 3

[0054] Such as figure 1 As shown, a gas-fired boiler and solar energy hybrid energy heating system, its structure is compared with the embodiment 2, the difference is: the connecting pipeline between the hot water storage tank 2 and the channel A is provided with an electric valve-3, and The electric valve one 3 communicates with the electric valve three 10 . The electric valve-3 can be set in the pipeline between the hot water storage tank 2 and the water pump-4, or the pipeline between the water pump-4 and the channel A. In this embodiment, the electric valve-3 can be set in the hot water storage tank On the pipeline between tank 2 and water pump one 4.

[0055] This embodiment is convenient to directly supply the water heated by solar energy to the end of the domestic hot water supply system 17. This situation is especially suitable for insufficient sunlight, and the temperature of the water flowing through the heat collector 1 is still relatively low after being heated. ...

The system comprises aheat collector, a hot water storage tank, a first electric valve, a first heat exchanger, a ground heating system, a fourth electric valve, a boiler gas heating system and a domestic hot water supplysystem, wherein a water inlet of the heat collector communicates with a water source; a water outlet of the heat collector, the hot water storage tank, the first electric valve, the first heat exchanger and the water inlet of the heat collector communicate sequentially; the first electric valve, the fourth electric valve and the domestic hot water supply system communicate sequentially; a circulating water outlet of the ground heating system, the boiler gas heating system, the first heat exchanger and a circulating water inlet of the ground heating system communicate sequentially; and the water source, the boiler gas heating system and the fourth electric valve communicate sequentially. The system solves the problems of resource waste and poor energy-saving and emission-reducing effects of an existing hybrid energy functional system, and has the advantages of high automation degree, simplicity and reliability.

Description

technical field [0001] The invention belongs to the field of energy saving and emission reduction, and relates to a gas boiler and solar heating system, in particular to a gas boiler and solar energy mixed energy heating system and a control method thereof. Background technique [0002] Because of its sufficient solar radiation intensity, high energy efficiency ratio, and obvious energy-saving effect, solar heat pumps have attracted the attention of many scholars and engineers. However, due to the strong influence of the weather and poor continuity, they cannot normal operation, thus limiting the use of solar energy for heating. [0003] In view of this, it is necessary to provide a combined heating system of solar heat pump and gas boiler, which can combine solar energy and gas boiler to reduce gas consumption while ensuring indoor heating demand in winter, so as to meet the needs of fully utilizing solar energy and energy saving and emission reduction , but the existing s...
