Description

Technical Field

[0001] The utility model relates to the technical field of solar energy heating, in particular to a solar energy coupled air energy heating device. Background Art

[0002] In recent years, heating methods have been changing, whether for commercial, domestic, urban or rural areas. Natural gas wall-mounted boilers, electric heaters, solar energy, air energy heat pumps, biomass and other energy sources have entered many households and commercial user sites. The basic principle of transformation in each region is "use gas if it is suitable, and use electricity if it is suitable". Among them, air energy heat pumps and solar energy have been seen by users among many energy sources due to their advantages of cleanliness, safety and energy saving, and the two can also be combined for heating.

[0003] Air energy heat pumps and solar energy have their own shortcomings when used alone. Although air energy heat pumps can adapt to the cold weather in northern winter, the heating efficiency will still be reduced in the low temperature environment in winter; and the solar heating system will be affected by the weather and solar radiation, and it is not possible to reach the required heat of the system every day. When using solar energy for heating, auxiliary heat sources must be equipped. Combining air energy with solar energy, using solar energy for heating when there is plenty of sunshine will consume less electricity. When there is no sun or insufficient sunlight, using air energy for heating will also reduce electricity consumption.

[0004] The announcement number is CN113483384A, and the name is a prior art of a solar-coupled air-energy heating device, which includes two solar transverse tubes, multiple solar vertical tubes and an air source heat pump unit. A solar heating mechanism is provided on the front side of the solar transverse tubes and the solar vertical tubes, and an air-source heat pump unit is provided on the front side of the air source heat pump unit. The solar heating mechanism includes a first hot water tank, a first water pump is fixedly provided on the top of the first hot water tank, a heat exchange plate is provided inside the first hot water tank, and two connecting pipes are fixedly provided on one side of the first hot water tank.

[0005] By combining the solar energy heating mechanism and the air energy heating mechanism to provide heating, energy saving is achieved. The solar panels are generally placed outside the house where they can be exposed to sunlight. If the solar panels are not protected in rainy and snowy weather, their service life will be easily reduced. In addition, a hot water tank is set separately for solar energy and air energy, instead of realizing the conversion function in the same hot water tank, which increases the production cost. A single spiral heat exchange tube has a limited contact area with the cold water, and the cold water cannot be heated up quickly. Utility Model Content

[0027] A solar-coupled air-energy heating device comprises an air-energy heat pump 1 and a solar panel group 2. The air-energy heat pump 1 and the solar panel group 2 are respectively connected to a water tank 4 through a heating pipe 3 and a return pipe 13. The heating pipe 3 comprises an air-energy heating pipe 18 and a solar heating pipe 19. The return pipe 13 comprises an air-energy return pipe 20 and a solar return pipe 21. The air-energy heating pipe 18, the solar heating pipe 19, the air-energy return pipe 20 and the solar return pipe 21 are all provided with a pump body 22.

[0028] When there is sufficient solar energy, the pump body 22 can be started to supply heat to the water tank 4 through the solar heating pipe 19. After heat exchange in the double-layer spiral heat exchange tube 5, the heat-absorbing medium flows back to the solar panel group 2 from the solar return pipe 21. At this time, the pump body 22 of the air energy heating pipe 18 is in a closed state.

[0029] When solar energy is insufficient and the air energy heat pump 1 is needed for heating, the pump body 22 located in the solar energy heating pipe 19 is closed, and the pump body 22 in the solar energy return pipe 21 is started to transport the heat absorbing medium to the solar panel group 2. Then the pump body 22 in the air energy heating pipe 18 is opened, so that the air energy enters the double-layer spiral heat exchange pipe 5 from the bottom connecting pipe 17, exchanges heat with the cold water outside, and then flows back to the air energy heat pump 1 from the air energy return pipe 20.

[0030] One end of the air energy heating pipe 18 and the air energy return pipe 20 are connected to the bottom connecting pipe 17 and the top connecting pipe 16 respectively, and the other end is connected to the air energy heat pump 1. The air energy enters the double-layer spiral heat exchange pipe 5 from the bottom connecting pipe 17, and then is discharged from the top connecting pipe 16 to the air energy return pipe 20. One end of the solar energy heating pipe 19 and the solar energy return pipe 21 are connected to the top connecting pipe 16 and the bottom connecting pipe 17 respectively, and the other end is connected to the solar panel 8. The heat absorbing medium enters the double-layer spiral heat exchange pipe 5 from the top connecting pipe 16, and then enters the solar energy return pipe 21 from the bottom connecting pipe 17.

[0031] A double-layer spiral heat exchange tube 5 is arranged inside the water tank 4, and the double-layer spiral heat exchange tube 5 includes an outer spiral heat exchange tube 14 and an inner spiral heat exchange tube 15, which enhances the contact area between the double-layer spiral heat exchange tube 5 and water, making the temperature rise faster. The top and bottom of the outer spiral heat exchange tube 14 and the inner spiral heat exchange tube 15 are respectively connected to the same top connecting tube 16 and bottom connecting tube 17.

[0032] The water tank 4 is connected to the floor heating terminal pipe 6. The top wall and bottom wall of the water tank 4 are respectively provided with a water inlet pipe 27 and a drain pipe 28 for water inlet and drain. A hot water pipe 29 and a cold water pipe 30 are provided through the side wall of the water tank 4. The hot water pipe 29 and the cold water pipe 30 are both connected to the floor heating terminal pipe 6, and a pump body 22 is also provided inside them.

[0033] The hot water in the water tank 4 flows from the hot water pipe 29 to the floor heating terminal pipe 6. After one circle, the temperature is reduced and returns to the inside of the water tank 4 through the cold water pipe 30 to be heated again.

[0034] The solar panel group 2 includes two support frames 7 that are fixedly connected at an angle, and the angle is preferably within 90 degrees, forming a triangular frame with the ground to enhance stability. Solar panels 8 are evenly distributed on the two support frames 7, and a heat-absorbing medium flows inside the solar panels 8. A group of reciprocating screws 9 and a group of fixed blocks 10 are symmetrically arranged above the two support frames 7. The fixed blocks 10 are fixedly connected to an elastic waterproof cloth 11, and the other end of the elastic waterproof cloth 11 is fixedly connected to a movable block 12, and the movable block 12 is slidably arranged on the periphery of the reciprocating screw 9.

[0035] A support plate 23 is fixedly provided at the top connection of the two support frames 7, and a double-headed motor 24 is provided on the top wall of the support plate 23 through a mounting frame. A group of cross plates 25 parallel to a group of reciprocating screw rods 9 are provided on the top wall of the support plate 23, and a limiting groove 26 is provided on the cross plate 25. A group of reciprocating screw rods 9 are fixedly connected to the two output shafts of the double-headed motor 24 respectively.

[0036] When it rains or snows, start the double-headed motor 24 to drive a set of reciprocating screws 9 to rotate, so that the two ends of the movable block 12 move outward along the reciprocating screw 9 under the limiting action of the limiting groove 26, thereby driving the elastic waterproof cloth 11 to unfold, block the rain and snow, and avoid damaging the solar panel 8. When the sun goes out and needs to be folded up, start the double-headed motor 24 in the reverse direction, so that the elastic waterproof cloth 11 is driven by the movable block 12 to be folded on the support plate 23, so that the solar panel 8 can absorb solar energy conveniently.

[0037] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
