Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, specifically to an air source heat pump efficiency enhancement device. Background Technology

[0002] An air source heat pump is a system that uses heat from the air for heating or cooling. Based on thermodynamic principles, it achieves this by circulating a fluid (usually a refrigerant) between an evaporator, compressor, condenser, and expansion valve. This process absorbs heat from a low-temperature region, compresses and heats it, and then releases it to a high-temperature region. In heating mode, the heat pump absorbs heat from the environment, heats it, and delivers it to the space requiring heating. In cooling mode, it conversely extracts heat from the room and releases it to the outside environment. The heating efficiency of an air source heat pump is affected by the ambient temperature. In northern regions where there is often plenty of sunshine and low temperatures, the air source heat pump will use more electricity to compress air to convert it into heat for heating.

[0003] For example, patent CN221881833U discloses an air source heat pump efficiency enhancement device, including: a telescopic bracket, a heat absorption cover, and a crossbar; the bottom of the telescopic bracket is fixedly connected to a mounting base, which is used for detachable connection to the ground, and the top of the telescopic bracket is detachably connected to a T-junction; the heat absorption cover is detachably connected to the telescopic bracket; both ends of the crossbar are detachably connected to the T-junction, and its bottom is detachably connected to the top of the heat absorption cover; this utility model has the characteristics of simple and quick installation and disassembly, which can reduce energy consumption, improve heating efficiency, and at the same time improve the defrosting rate to a certain extent, and protect the outdoor unit of the air source heat pump, providing users with a more convenient, efficient and economical heating solution.

[0004] However, during the process of drawing in air, the air source heat pump efficiency enhancement device described above cannot allow the heat exchanger to fully contact the air, resulting in reduced heat transfer. The system needs to take longer to obtain sufficient heat from the outside air, thereby reducing the overall thermal efficiency of the system. Utility Model Content

[0005] The purpose of this invention is to provide an air source heat pump efficiency enhancement device to solve the problem mentioned in the background art that the heat exchanger cannot be in full contact with the air, resulting in reduced heat transfer.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An air source heat pump efficiency enhancement device includes: an air source heat pump body, with two sets of air inlets connected and installed on the upper surface of the air source heat pump body. Each of the two sets of air inlets has a bearing seat fixedly installed inside. A fan blade is inserted into the inner ring of the bearing seat. A heat exchange mechanism is fixedly installed on the upper half of the air source heat pump body. The heat exchange mechanism is located at the lower end of the air inlets and is connected to them, so that the compressor in the air source heat pump body compresses the refrigerant gas after absorbing heat from the evaporator, raising its temperature to prepare for subsequent heat exchange.

[0008] Preferably, a convex cover is fixedly installed between the two sets of air inlets, a motor is fixedly installed on the lower inner surface of the convex cover, a transmission column is fixedly installed at one end of the output shaft of the motor, two sets of transmission belts are fitted on the outer surface of the transmission column, and the other ends of the two sets of transmission belts are respectively fitted into the embedded annular grooves opened on the outer surface of the rotating rods of the two sets of fan blades.

[0009] Preferably, the heat exchange mechanism includes two sets of triangular plates, which are fixedly installed in the upper half of the air source heat pump body, and heat exchange tubes are fixedly installed on both sides between the two sets of triangular plates.

[0010] Preferably, the two sets of heat exchange tubes are spliced ​​on both sides of the triangular plate to form a V-shape and are flush with the two sets of air inlet pipes.

[0011] Preferably, the V-shaped structure increases the contact time and contact area between the air and the surface of the heat exchange tube, while allowing the air to flow in two directions, which helps to reduce the boundary layer thickness, further promotes heat transfer, and thus improves the efficiency of heat exchange.

[0012] Preferably, one end of the inlet of each of the two sets of heat exchange tubes is connected to a connecting pipe, and the outlet of each of the two sets of heat exchange tubes is connected to a three-way pipe. The three-way pipe passes through the lower half of the air source heat pump body and is connected to the insulated water tank. The connecting pipe is connected to the water pump.

[0013] Preferably, a removable dustproof mesh cover is provided on the outer side of the air inlet. The dustproof mesh cover is used to block dust, debris, and other impurities in the outside air from entering the air inlet, preventing these impurities from clogging or wearing the fan blades and heat exchange mechanism, thereby extending the service life of the equipment and maintaining its efficient operation.

[0014] Preferably, the motor is a variable frequency motor, and the air source heat pump efficiency enhancement device further includes a variable frequency controller. The variable frequency controller automatically adjusts the motor speed based on the load changes of the air source heat pump body and the ambient temperature, thereby adjusting the fan blade speed and air intake to adapt to different operating conditions and further improve energy efficiency and energy saving. At the same time, the use of a variable frequency controller also helps reduce the starting current surge of the equipment and extend the service life of the motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the design of the air inlet, fan blades, motor, transmission belt and heat exchange mechanism, when in use, the motor can be started to drive the transmission column fixedly installed on the lower surface of the output shaft to rotate. This enables the transmission belt on the outer surface of the transmission column to drive the two sets of fan blades to rotate synchronously in the air inlet. The synchronously rotating fan blades can effectively increase the air flow, introduce more air into the air source heat pump body, enhance the contact area between the heat exchange mechanism and the air for heat exchange, and thus improve the heat exchange efficiency of the system.

[0017] 2. Through the design of the triangular plate, heat exchange tube, and tee pipe, the fan blades draw air into the air source heat pump body, causing the air to be blown onto the surface of the V-shaped heat exchange tube. The V-shaped structure allows the air to flow in two directions, avoiding a single-direction flow path and increasing the complexity of the airflow. This helps to better exchange heat with the heat exchange tube. Furthermore, the air velocity changes as the airflow follows the V-shaped path, which can effectively reduce the boundary layer thickness of the airflow. The presence of the boundary layer reduces the heat transfer efficiency, so reducing the boundary layer thickness can further improve the heat exchange efficiency, significantly improving both the speed and efficiency of heat transfer.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 This embodiment provides the following technical solution:

[0024] like Figures 1-2 As shown, an air source heat pump efficiency enhancement device includes: an air source heat pump body 1, with two sets of air inlet ports 101 connected and installed on the upper surface of the air source heat pump body 1, bearing seats 107 fixedly installed in each of the two sets of air inlet ports 101, and fan blades 103 inserted into the inner ring of the bearing seats 107. A heat exchange mechanism 2 is fixedly installed in the upper half of the air source heat pump body 1. The heat exchange mechanism 2 is located at the lower end of the air inlet ports 101 and is connected to them, so that the compressor in the air source heat pump body 1 compresses the refrigerant gas after absorbing heat from the evaporator, raising its temperature to prepare for subsequent heat exchange.

[0025] A convex cover 102 is fixedly installed between the two sets of air inlets 101. A motor 104 is fixedly installed on the lower inner surface of the convex cover 102. A transmission column 105 is fixedly installed at one end of the output shaft of the motor 104. Two sets of transmission belts 106 are fitted on the outer surface of the transmission column 105. The other ends of the two sets of transmission belts 106 are respectively fitted into the embedded annular grooves opened on the outer surface of the rotating rods of the two sets of fan blades 103.

[0026] Through the design of the air inlet 101, fan blades 103, motor 104, transmission belt 106, and heat exchange mechanism 2, during use, the transmission column 105 fixedly mounted on the lower surface of the output shaft can be rotated by starting the motor 104. This allows the transmission column 105 to drive the transmission belt 106 mounted on the outer surface to drive the two sets of fan blades 103 to rotate synchronously within the air inlet 101. The synchronously rotating fan blades 103 can effectively increase the airflow, introduce more air into the air source heat pump body 1, enhance the contact area between the heat exchange mechanism 2 and the air for heat exchange, and thus improve the heat exchange efficiency of the system.

[0027] like Figure 3 As shown, the heat exchange mechanism 2 includes two sets of triangular plates 201. The two sets of triangular plates 201 are fixedly installed in the upper half of the air source heat pump body 1, and heat exchange tubes 202 are fixedly installed on both sides between the two sets of triangular plates 201.

[0028] Among them, the two sets of heat exchange tubes 202 are spliced ​​on both sides of the triangular plate 201 to form a V shape and are flush with the two sets of air inlet ports 101.

[0029] The V-shaped structure increases the contact time and area between the air and the surface of the heat exchange tube 202, while allowing the air to flow in two directions. This helps to reduce the boundary layer thickness, further promotes heat transfer, and thus improves the efficiency of heat exchange.

[0030] The inlet of each of the two heat exchange tubes 202 is connected to a connecting pipe 204. The outlet of each heat exchange tube 202 is connected to a three-way pipe 203. The three-way pipe 203 passes through the lower half of the air source heat pump body 1 and is connected to the insulated water tank. The connecting pipe 204 is connected to the water pump.

[0031] Through the design of the triangular plate 201, heat exchange tube 202, and three-way pipe 203, during the process of the fan blade 103 drawing air into the air source heat pump body 1, the air will be blown onto the surface of the V-shaped heat exchange tube 202. The V-shaped structure allows the air to flow in two directions, avoiding a single-direction flow path and increasing the complexity of the air flow. This helps to better exchange heat with the heat exchange tube 202. Furthermore, when the air flows along the V-shaped path, the air velocity will change, which can effectively reduce the boundary layer thickness of the airflow. The presence of the boundary layer will reduce the heat transfer efficiency. Therefore, reducing the boundary layer thickness can further improve the heat exchange efficiency, and significantly improve both the heat transfer speed and efficiency.

[0032] The air inlet 101 is equipped with a detachable dustproof screen on its outer side. The dustproof screen is used to block dust and debris in the outside air from entering the air inlet 101, preventing these impurities from clogging or wearing the fan blades 103 and the heat exchange mechanism 2, thereby extending the service life of the equipment and maintaining its efficient operation.

[0033] The motor 104 is a variable frequency motor, and the air source heat pump efficiency enhancement device also includes a variable frequency controller. The variable frequency controller automatically adjusts the speed of the motor 104 based on the load changes of the air source heat pump body 1 and the ambient temperature, thereby adjusting the speed of the fan blades 103 and the air intake volume to adapt to different operating conditions and further improve energy efficiency and energy saving. At the same time, the use of the variable frequency controller also helps reduce the starting current surge of the equipment and extend the service life of the motor.

[0034] Based on the above technical solution, the working steps of this solution are summarized as follows: In use, the drive column 105 fixedly installed on the lower surface of the output shaft can be rotated by starting the motor 104. This allows the drive column 105 to drive the drive belt 106 on the outer surface to drive the two sets of fan blades 103 to rotate synchronously in the air inlet 101. The synchronously rotating fan blades 103 can draw in outside air and blow it onto the surface of the V-shaped heat exchange tube 202. This allows the refrigerant in the heat exchange tube 202 to exchange heat with the air, thus achieving heat transfer. Furthermore, the air being blown onto the surface of the heat exchange tube 202 increases the contact area between the air and the heat exchange tube 202, improving the heat exchange efficiency. This enhances the heating effect of the air source heat pump body 1 and improves the heating efficiency.

[0035] In summary: By using V-shaped heat exchange tubes 202 to contact the intake air, a unidirectional flow path is avoided, increasing the complexity of the airflow. This facilitates better heat exchange with the heat exchange tubes 202. Furthermore, as the airflow follows the V-shaped path, the air velocity changes, effectively reducing the boundary layer thickness. The presence of the boundary layer reduces heat transfer efficiency, so reducing the boundary layer thickness further improves heat exchange efficiency, significantly enhancing both the speed and efficiency of heat transfer. This, in turn, enhances the heating effect of the air source heat pump body 1 and improves heating efficiency.
