Abstract
Description
Technical Field
[0001] This utility model relates to the field of air source heating technology, and in particular to a heating system for air source coupled with fluorine-coated split radiators. Background Technology
[0002] With people's increasing demands for quality of life and growing awareness of energy conservation and environmental protection, air source heat pumps, as an efficient and clean energy utilization method, are being used more and more widely in the heating field. However, for heating single rooms or small areas, the methods are relatively limited, such as ordinary air conditioning, heat pump air conditioning, coal boilers, or electric heating. These methods have drawbacks such as unsatisfactory heating effects, discomfort, environmental pollution, high energy consumption, and cumbersome operation. There is an urgent need to develop a heating method specifically for single rooms or small areas to solve the problems of conventional heating methods and meet the diverse needs of the market. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a heating system with air source heat pump coupled with fluorine split radiator to address the shortcomings of the existing technology. This invention generates heat through air source heat pump unit circulation and supplies it to split heat exchange components, which exchange heat efficiently with the water in the radiator. It has the advantage of efficiently completing indoor heating, especially in small spaces and different spaces.
[0004] The technical problem to be solved by this utility model is achieved through the following technical solution: a heating system of air source coupled with fluorine split radiators, including an air source heat pump unit with a plurality of fluorine split radiators connected in parallel, each fluorine split radiator including a plurality of vertically arranged heat exchange fins, a heat exchange manifold communicating with the heat exchange fins at the lower part of the heat exchange fins, a split heat exchange assembly inside the heat exchange manifold, the split heat exchange assembly including a bent and coiled heat exchange tube, one end of the heat exchange tube being a refrigerant inlet, the other end of the heat exchange tube being a refrigerant outlet, the refrigerant inlet and the refrigerant outlet being connected to the air source heat pump unit to form a refrigerant circulation loop.
[0005] Air source heat pump units utilize heat from the air as the primary heat source, using a small amount of electricity to drive a compressor, converting low-temperature heat into high-temperature heat. Their energy efficiency ratio (COP=3-5) is significantly more energy-efficient than traditional electric heating methods (COP=1).
[0006] The heat exchange manifold is located below the heat exchange fins, allowing for timely water circulation with the water in the fins. The water in the heat exchange manifold exchanges heat with the separate heat exchange components, resulting in high heat exchange efficiency, low heat loss, and energy savings.
[0007] By installing different numbers of refrigerant-based split radiators in rooms of varying sizes, energy savings are achieved while ensuring heat exchange.
[0008] As a further embodiment of this utility model, the split heat exchange assembly includes a multi-layer heat exchange tube bank consisting of three heat exchange tubes as a group. The three heat exchange tubes are bent at 180° in the same direction and simultaneously, forming a multi-layer parallel arrangement from bottom to top. The cross-section of the multi-layer heat exchange tube bank forms a rectangular heat exchange surface. The three heat exchange tubes at the bottom of the multi-layer heat exchange tube bank converge to form a refrigerant inlet, and the three heat exchange tubes at the top of the multi-layer heat exchange tube bank converge to form a refrigerant outlet. The refrigerant inlet and the refrigerant outlet are located on the same side, and both the refrigerant inlet and the refrigerant outlet are provided with connecting copper pipes that are connected to the refrigerant circulation loop.
[0009] Multi-layer heat exchanger tube bank greatly increases the heat exchange area. The structure of three heat exchanger tubes per layer makes the contact area between the refrigerant and the air larger. Moreover, the cross-section of the multi-layer heat exchanger tube bank forms a rectangular heat exchange surface, making the structure more compact and better adaptable to the installation needs of different spaces, saving installation space.
[0010] As a further embodiment of this invention, the heat exchange manifold is provided with a plurality of evenly distributed baffles along its length. The baffles have perforations through which heat exchange tubes pass, and water flow holes are provided between the periphery of the baffles and the inner wall of the heat exchange manifold. The shape and dimensions of the baffles correspond to those of the inner wall of the heat exchange manifold. When the fluid flows within the heat exchange manifold, the baffles cause turbulence, disrupting the fluid boundary layer and reducing thermal resistance, thereby significantly improving heat exchange efficiency. The disruption of the boundary layer also allows for more efficient heat transfer between the hot and cold fluids.
[0011] As a further embodiment of this invention, the heat exchange manifold is closed at one end and has a manifold end plate at the other end. The manifold end plate has pipe holes through which heat exchange tubes pass, and mounting holes are provided on both sides of the manifold end plate. The manifold end plate is detachably installed to the end of the heat exchange manifold through the mounting holes. The detachable installation of the manifold end plate and the heat exchange manifold facilitates disassembly and assembly, and ensures the sealing performance of the heat exchange space inside the manifold.
[0012] As a further aspect of this invention, a refrigerant, specifically R410a, is circulated in the refrigerant circulation loop and the split heat exchange assembly. R410a does not damage the ozone layer and is highly efficient and environmentally friendly.
[0013] As a further embodiment of this invention, the heat exchange manifold and heat exchange fins are internally circulated with heating water, which exchanges heat with the refrigerant in the heat exchange manifold through a multi-layer heat exchange tube array. The multi-layer heat exchange tube array, situated within the same installation space, significantly increases the heat exchange area and achieves high heat exchange efficiency.
[0014] The beneficial effects of this utility model are as follows: This utility model provides a heating system for air-source heat pump coupled with fluorine-coated split radiators, including an air-source heat pump unit with several fluorine-coated split radiators connected in parallel. Each fluorine-coated split radiator includes several vertically arranged heat exchange fins. The lower part of each heat exchange fin is provided with a heat exchange manifold communicating with the heat exchange fins. The heat exchange manifold contains a split heat exchange assembly, which includes a bent and coiled heat exchange tube. One end of the heat exchange tube is designated as a refrigerant inlet, and the other end is designated as a refrigerant outlet. The refrigerant inlet and refrigerant outlet are connected to the air-source heat pump unit to form a refrigerant circulation loop.
[0015] Air source heat pump units utilize the heat in the air as the main heat source, and use a small amount of electricity to drive the compressor to convert the low-temperature heat source into a high-temperature heat source, resulting in significant energy savings.
[0016] The heat exchange manifold is located below the heat exchange fins, allowing for timely water circulation with the water in the fins. The water in the heat exchange manifold exchanges heat with the separate heat exchange components, resulting in high heat exchange efficiency, low heat loss, and energy savings.
[0017] The arrangement of multiple heat exchange tubes in the same installation space greatly increases the heat exchange area and results in high heat exchange efficiency.
[0018] By installing different numbers of refrigerant-based split radiators in rooms of varying sizes, energy savings are achieved while ensuring heat exchange. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0024] like Figures 1 to 8 As shown, a heating system with air source heat pump coupled with fluorinated split radiators includes an air source heat pump unit 1 connected in parallel with several fluorinated split radiators 2. The number of fluorinated split radiators is configured according to different indoor space sizes.
[0025] The refrigerant-based split radiator includes several vertically arranged heat exchange fins 201. A heat exchange manifold 202, communicating with the heat exchange fins, is located at the lower part of each fin. A split heat exchange assembly 3 is housed within the manifold. The split heat exchange assembly includes a coiled heat exchange tube, with one end of the tube serving as a refrigerant inlet 312 and the other end as a refrigerant outlet 311. The refrigerant inlet and outlet are connected to an air-source heat pump unit to form a refrigerant circulation loop 101. Refrigerant, specifically R410a, circulates within the refrigerant circulation loop and the split heat exchange assembly.
[0026] The split heat exchange assembly 3 includes a multi-layer heat exchange tube bank consisting of three heat exchange tubes as a group. The three heat exchange tubes are bent at 180° in the same direction and simultaneously, forming a multi-layer parallel arrangement from bottom to top. The cross-section of the multi-layer heat exchange tube bank forms a rectangular heat exchange surface. The three heat exchange tubes at the bottom of the multi-layer heat exchange tube bank converge to form a refrigerant inlet, and the three heat exchange tubes at the top of the multi-layer heat exchange tube bank converge to form a refrigerant outlet. The refrigerant inlet and refrigerant outlet are located on the same side. Both the refrigerant inlet and refrigerant outlet are equipped with connecting copper pipes 301 that are connected to the refrigerant circulation loop. The connecting copper pipes are water distributors.
[0027] After being heated in the air source heat pump unit, the refrigerant continuously circulates along the refrigerant circulation loop, entering the corresponding multi-layer heat exchanger tube arrays through the parallel refrigerant inlets. The refrigerant inlets are located below the refrigerant outlets. The refrigerant first enters the first layer of heat exchanger tube arrays along the refrigerant inlets, then changes direction by 180° at the end to enter the second layer of heat exchanger tube arrays, and so on into the third layer of heat exchanger tube arrays.
[0028] When the high-temperature refrigerant flows through the multi-layer heat exchanger tube bank, it comes into full contact with the water in the heat exchanger header, exchanging heat and reaching the target water temperature in a short time. This releases heat into the room, promptly raising the indoor temperature.
[0029] The heat exchange manifold is provided with five evenly distributed baffles 303 along its length. The baffles are provided with pipe holes 331 through which heat exchange tubes pass. Water flow holes 332 are provided between the four periphery of the baffles and the inner wall of the heat exchange manifold. The shape and size of the baffles are matched to the inner wall of the heat exchange manifold.
[0030] During installation, five baffles are sequentially installed on the multi-layer heat exchanger tube bank. The baffles 303 are equidistant. After the multi-layer heat exchanger tube bank and the baffles are fitted together, the entire structure is inserted into the heat exchanger header 202. One end of the heat exchanger header is closed until the tail end of the multi-layer heat exchanger tube bank extends to the sealed end of the heat exchanger header.
[0031] The other end of the heat exchanger is provided with a header end plate 302, which has pipe holes through which heat exchange tubes pass. Mounting holes 321 are provided on both sides of the header end plate. The header end plate can be detachably installed to the end of the heat exchanger through the mounting holes.
[0032] The heat exchanger header has a threaded blind hole at its end that mates with the mounting hole. Screws are passed through the mounting hole and screwed into the threaded blind hole in sequence. This creates a sealed and stable mounting space inside the heat exchanger header.
[0033] The heat exchange manifold 202 and the heat exchange fins 201 are internally circulated with heating water. The water is heated by heat exchange in the heat exchange manifold, and the water density decreases as it moves upward and enters the heat exchange fins to exchange heat with the indoor cold air. Meanwhile, the water in the heat exchange fins, which has a relatively low temperature and high density, flows into the heat exchange manifold. The low-temperature heating water exchanges heat with the refrigerant in the heat exchange manifold through a multi-layer heat exchange tube array.
[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
