Description

Technical Field

[0001] The present invention relates to the technical field of heating equipment, and in particular to a multi-energy complementary heating equipment. Background Art

[0002] Usually, hotels, factories, schools, institutions and homes use central heating or a single device to provide heat source for heating. This method can meet the heating requirements, but there are problems such as high energy consumption, poor environmental protection, and inflexible heating. It does not meet the requirements of low-carbon environmental protection, and cannot meet the country's policies on the effective use of resources and circular economy, and cannot achieve cleaner, healthier and more sustainable energy utilization. Summary of the invention

[0003] The purpose of the present invention is to provide a multi-energy complementary heating equipment, which, through the action of the controller, ensures that different heating combinations are adopted in different stages, thereby achieving the requirements of low energy consumption and low pollution, complying with the national energy-saving and environmental protection policies, meeting the user's requirements for economic heating, and promoting social environmental protection and sustainability in energy utilization and economic development.

[0004] According to one purpose of the present invention, the present invention provides a multi-energy complementary heating device, including an air energy heat exchange system, a gas combustion heat exchange system and a controller, wherein the above systems are uniformly controlled by the controller according to a set program. The air energy heat exchange system described in the present invention includes a refrigerant inlet, a thin coil, and a refrigerant outlet, and the gas combustion heat exchange system includes a burner, a furnace, a smoke exhaust pipe, a water inlet, an inner coil, an outer coil, and a water outlet.

[0005] Furthermore, the air energy heat exchange system and the gas combustion heat exchange system are controlled by a controller to realize intelligent combined heating. The controller controls the operation of different heating systems in real time in combination with environmental protection and economy. When the electricity price is low at night or the temperature is high at noon, the air energy heat exchange system can be used for heating. When the temperature is low and the electricity consumption is at peak, the gas combustion heat exchange system can be used for heating. In combination with the heating load, the two methods can be controlled to provide heating at the same time.

[0006] Furthermore, the burner is located in the furnace at the center of the gas combustion heat exchange system, and the inner coil and the outer coil are arranged in spirals with different radii with the burner as the center.

[0009] Furthermore, the furnace wall includes the inner coil, the outer coil, the thin coil and the burner inside.

[0010] Furthermore, the inner coil and the outer coil may be finned tubes or plain tubes.

[0011] The technical solution of the present invention is to organically combine the air energy heat exchange system and the gas combustion heat exchange system through the operation of the controller, so as to achieve the economy, environmental protection and safety of heating.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Figure 1 , Figure 2 Shown

[0020] A multi-energy efficient heating device includes a gas combustion heat exchange system consisting of a burner 2, a furnace 15, a smoke exhaust pipe 9, a water inlet 16, an inner coil 3, and an outer coil 12, and an air energy heat exchange system consisting of a refrigerant 13, a refrigerant inlet 14, a thin coil 11, and a refrigerant outlet 16.

[0021] When the gas combustion heat exchange system of the present invention works normally, the premixed gas 1 with a certain pressure enters the burner 2 from the upper part of the equipment and ignites and burns. The heat generated by the combustion and the flue gas 10 first flow through the inner coil 3 and the heat is absorbed by the warm water in the inner coil 3, and then flow through the outer coil 12. The residual heat is further absorbed by the cold water in the outer coil 12. The flue gas 10 that has fully absorbed the heat finally flows out of the heating equipment through the exhaust port 9. For details of the flue gas flow direction, see Figure 1 Indicated by the dashed arrow.

[0022] At the same time, cold water 4 with a certain pressure flows into the outer coil 12 from the water inlet 5, and the water flows spirally upward in the outer coil 12, absorbing the residual heat in the flue gas 10, and the temperature continues to rise. After turning at the top, it flows into the inner coil 3. The warm water flowing into the inner coil 3 further absorbs the heat generated by the combustion of the premixed gas 1. In the process of spiral flow from top to bottom, the temperature gradually increases, and finally becomes hot water 6, which flows out of the heating equipment from the water outlet 7. For details of water flow direction, see Figure 1 Indicated by the solid arrow.

[0023] When the air energy heat exchange system of the present invention is working, the refrigerant 13 that absorbs heat through the external air energy equipment flows from the refrigerant inlet 14 into the thin coil 11 inside the outer coil 12, flows from top to bottom, and the heat is transferred to the water flow between the outer coil 12 and the thin coil 11. The water temperature continues to rise, and heat exchange is achieved. Figure 1 Indicated by the thin solid arrow.

[0024] At the same time, cold water 4 with a certain pressure flows into the outer coil 12 from the water inlet 5, and the water flows spirally upward in the outer coil 12, absorbing the heat of the refrigerant 13 in the central thin coil 11. The water temperature continues to rise, and at the top turn, it flows into the inner coil 3. At this time, the cold water 4 is transformed into hot water 6, and the hot water 6 flows spirally from top to bottom along the inner coil 3, and finally flows out of the heating equipment from the water outlet 7. For details on the water flow direction, see Figure 1 Indicated by the solid arrow.

[0025] The device is also equipped with a controller, which controls the operation of different heating systems in real time in combination with environmental protection and economy. When the electricity price is low at night or the temperature is high at noon, the air energy heat exchange system can be used for heating. When the temperature is low or the electricity consumption is at peak, the gas combustion heat exchange system can be used for heating. Combined with the heating load situation, the two methods can also be controlled for heating at the same time.

[0026] like Figure 3 As shown, according to the actual heat transfer efficiency, the inner coil and the outer coil can use finned tubes 1-1 or plain tubes 1-2.

[0027] Finally: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
