Description

Technical Field

[0001] The present invention relates to the technical field of heat pumps, and in particular to an integrated air energy heat pump and a use method thereof. Background Art

[0002] The air-source heat pump is mainly composed of four major components: evaporator, condenser, compressor and expansion valve. The basic principle of the air-source heat pump is based on the compression refrigeration cycle. It uses refrigerant as a carrier to absorb or discharge heat from the atmosphere to meet the needs of heating or cooling. It has the advantages of high efficiency and energy saving, environmental protection and pollution-free, safety and reliability. It can be used for household hot water supply, indoor heating, hot water and drying operations in commercial places, etc. It is widely used in many places such as homes, hotels, schools, and hospitals.

[0003] The evaporator is a key component of the air-to-energy heat pump system that absorbs heat from the external environment. The evaporator consists of internal pipes and external fins. The pipes contain refrigerant, and the fins are used to increase the contact area with the air. When air flows through the evaporator, heat is transferred from the air to the fins, and then conducted to the refrigerant in the pipes through the fins. The heat in the air is absorbed by the refrigerant in the evaporator for heat exchange (in heating mode, the working principle of the evaporator is similar to that in cooling mode, but the direction of heat transfer is opposite).

[0004] Poor heat exchange in the evaporator will lead to a decrease in the cooling (heating) effect of the air-to-heat pump. It may also cause abnormal evaporation temperature and pressure of the refrigerant in the evaporator, affecting the normal operation of the entire refrigeration cycle and even triggering the low-pressure protection device, causing the system to shut down.

[0005] The main reasons for poor heat exchange of the evaporator are as follows: First, the frosting problem. When the surface temperature of the evaporator is lower than the dew point temperature of the air, the water vapor in the air will condense into frost on the surface of the evaporator. The presence of the frost layer will greatly increase the thermal resistance and hinder the transfer of heat from the air to the refrigerant. As the frost layer thickens, it will seriously affect the heating performance of the heat pump, resulting in a decrease in the heating capacity of the heat pump and increased energy consumption. Even in the case of severe frosting, the system may not be able to operate normally; Second, the dust accumulation problem. During operation, the evaporator will constantly come into contact with the outside air. Dust and impurities in the air adhere to the surface of the evaporator, which will increase the resistance to heat transfer and reduce the heat exchange efficiency of the evaporator; Third, insufficient air flow. The normal operation of the evaporator depends on sufficient air flow. If the fan fails or the air duct is blocked, the air flow through the evaporator will be reduced, reducing the heat exchange efficiency.

[0006] For the latter two points, the current solution is to regularly clean the dust on the surface of the evaporator and clean the air duct. The frost problem is one of the core focuses of the current research and development of air-energy heat pumps. The existing defrosting methods of air-energy heat pumps are mainly divided into reverse cycle defrosting, hot gas bypass defrosting and thermoelectric defrosting, etc. However, the above defrosting methods have the problem of uneven defrosting. The parts close to the heat source are defrosted thoroughly, and the parts far from the heat source cannot be effectively defrosted. Moreover, the frost melts into liquid water and flows down the surface of the evaporator. Under normal circumstances, the water will evaporate naturally, but in a low temperature environment, the water condenses into ice at the bottom of the evaporator before it evaporates, and then moves upward along the bottom of the evaporator, accumulating thicker and thicker, affecting the heat exchange of the evaporator. Some water will also drip onto the pipes of the condenser, compressor and expansion valve located below the evaporator, and freeze on the pipes. Summary of the invention

In addition, the fan effectively shortens the residence time of the air on the surface of the evaporator, thereby reducing the probability of water vapor in the air condensing on the surface of the evaporator, effectively preventing the formation of frost;

[0033] 2. When switched to the dust removal mode, the air duct can not only remove dust from the evaporator surface according to the set time period, but also turn to remove dust from the ventilation plate, effectively preventing the ventilation plate from being blocked by mesh holes and affecting air circulation;

[0034] 3. When switching to the defrost mode, the air duct moves from bottom to top for defrosting. During this process, the heat in the upper part of the air duct is dispersed to preheat and melt the frost layer, and the heat in the lower part of the air duct is concentrated to evaporate and dry the water droplets after defrosting. This design effectively avoids the problem of water droplets re-freezing after defrosting, and can also achieve the effect of fixed-point precise defrosting, avoiding uneven defrosting.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0053] Reference Figure 1 - Fig.16 An air energy heat pump integrated machine and a method of using the same include a machine body 1, an evaporator 2, a regulating module 3 and an air flow driving module 4. The interior of the machine body 1 is divided into an upper cabin 5 and a lower cabin 6. The evaporator 2, the regulating module 3 and the air flow driving module 4 are installed in the upper cabin 5 (a solar panel can be laid on the top of the machine body 1 to provide power to the regulating module 3 and the air flow driving module 4), and a condenser, a compressor and an expansion valve are installed in the lower cabin 6.

[0054] The evaporator 2 is installed at an angle in the upper cabin 5, the adjustment module 3 is installed on the outside of the evaporator 2 and remains parallel to the evaporator 2, and a ventilation plate 8 is installed on the side wall of the body 1 corresponding to the position of the upper cabin 5. The ventilation plate 8 remains parallel to the evaporator 2, and the ventilation plate 8 is used for air circulation in the outer area of ​​the evaporator 2.

[0055] A fan 7 is fixedly installed on the top of the upper cabin 5. The rotation of the fan 7 causes the surrounding air to flow continuously through the evaporator 2. The air flows on the fin surface of the evaporator 2. The heat is transferred from the air to the refrigerant in the evaporator 2, and the heat is absorbed by the refrigerant. The existence of the fan 7 ensures that sufficient air can contact the evaporator 2, thereby improving the efficiency of heat exchange in the evaporator 2. However, since the fan 7 is installed on the inner side of the evaporator 2, the fan 7 has a greater impact on the inner fins of the evaporator 2 and a limited impact on the outer fins of the evaporator 2. The airflow driving module 4 of the present application is installed on the outer side of the evaporator 2, which can enhance the disturbance degree of the air outside the evaporator 2, and can make the blowing direction of the airflow driving module 4 opposite to the blowing direction of the fan 7. The opposite air outlet directions make the flow of air on the surface of the evaporator 2 more complicated and turbulent, thereby improving the convective heat transfer coefficient between the air and the evaporator 2.

[0056] The airflow driving module 4 is installed on the adjustment module 3, and the adjustment module 3 includes an X-direction adjustment component 9 and a Y-direction adjustment component 10. The X-direction adjustment component 9 includes an X-direction optical rod 15, an X-direction screw rod 16 and an X-direction moving block 17. The X-direction moving block 17 is sleeved on the X-direction optical rod 15 and the X-direction screw rod 16, and the X-direction moving block 17 is slidably connected to the X-direction optical rod 15, and the X-direction moving block 17 is threadedly connected to the X-direction screw rod 16;

[0057] The Y-axis adjustment assembly 10 includes a Y-axis smooth rod 18, a Y-axis screw rod 19, a left Y-axis moving block 20 and a right Y-axis moving block 21. The Y-axis smooth rod 18 and the Y-axis screw rod 19 are respectively located on the left and right sides of the evaporator 2, and the directions of the Y-axis smooth rod 18 and the Y-axis screw rod 19 are parallel to the evaporator 2. At the same time, the upper and lower ends of the Y-axis smooth rod 18 are fixed in the upper cabin 5, and the upper and lower ends of the Y-axis screw rod 19 are rotatably installed in the upper cabin 5, and the Y-axis screw rod 19 is driven to rotate by a motor;

[0058] The left Y-direction moving block 20 is slidably mounted on the Y-direction optical rod 18, the right Y-direction moving block 21 is mounted on the Y-direction lead screw 19, the right Y-direction moving block 21 is threadedly connected to the Y-direction lead screw 19, the two ends of the X-direction optical rod 15 are respectively fixedly connected to the left Y-direction moving block 20 and the right Y-direction moving block 21; the two ends of the X-direction lead screw 16 are respectively rotationally connected to the left Y-direction moving block 20 and the right Y-direction moving block 21, and the X-direction lead screw 16 is driven to rotate by a motor.

[0059] The working principle of the regulation module 3 is as follows:

[0060] It is known that the Y-direction screw rod 19 is driven to rotate by a motor. Since the X-direction adjustment component 9, the left Y-direction moving block 20, and the right Y-direction moving block 21 can be regarded as a whole, when the Y-direction screw rod 19 rotates, the X-direction adjustment component 9, the left Y-direction moving block 20, and the right Y-direction moving block 21 will move up and down along the Y-direction screw rod 19 as a whole. Therefore, by driving the Y-direction screw rod 19 to rotate forward or reverse, the up and down position of the X-direction adjustment component 9 can be adjusted, that is, the up and down position of the airflow driving module 4 can be adjusted;

[0061] It is known that the X-axis screw rod 16 is driven to rotate by a motor. When the X-axis screw rod 16 rotates, the X-axis moving block 17 installed on the X-axis screw rod 16 will move left and right along the X-axis screw rod 16. Therefore, by driving the X-axis screw rod 16 to rotate forward or reverse, the left and right position of the airflow driving module 4 can be adjusted.

[0062] The airflow driving module 4 includes a steering component 11, a synchronous convergence component 12, an asynchronous convergence component 13 and an airflow guide plate 14. The steering component 11 includes an X-axis steering block 22 and a Y-axis steering block 23. The Y-axis steering block 23 is rotatably installed at the top center position of the X-axis moving block 17, and the Y-axis steering block 23 is driven to rotate by a motor. The Y-axis steering block 23 can be turned with the center position of the X-axis moving block 17 as the rotation center. The direction of the airflow guide plate 14 in the horizontal plane can be adjusted by rotating the Y-axis steering block 23. For example, by rotating the Y-axis steering block 23 180°, the airflow guide plate 14 can be changed from facing the evaporator 2 to facing the ventilation plate 8.

[0063] The X-axis steering block 22 and the Y-axis steering block 23 are rotatably connected via a rotating shaft, a main gear 24 is rotatably mounted on the Y-axis steering block 23, and a sub-gear 25 is fixedly mounted on the X-axis steering block 22, the sub-gear 25 meshes with the main gear 24, and the main gear 24 is driven to rotate by a motor, when the main gear 24 rotates, it drives the sub-gear 25 and the X-axis steering block 22 to rotate, and the X-axis steering block 22 rotates with the rotating shaft as the rotation center. Therefore, the X-axis steering block 22 is used to adjust the orientation of the airflow guide plate 14 in the vertical plane.

[0064] The synchronous convergence assembly 12 is fixedly mounted on the X-axis steering block 22. The synchronous convergence assembly 12 includes a fixed plate 26, a movable plate 27 and a convergence bracket 28. The fixed plate 26 is fixedly connected to the X-axis steering block 22 through a connecting column 29. The fixed plate 26, the connecting column 29 and the X-axis steering block 22 are fixed as a whole. A through hole is provided in the center of the fixed plate 26 and the connecting column 29 for fixing and installing a telescopic rod 30. The telescopic end of the telescopic rod 30 is fixedly connected to the center of the movable plate 27.

[0065] There are multiple convergence brackets 28, and the movable plate 27 has multiple upper mounting grooves 31 for installing the convergence bracket 28 evenly arranged along its own circumference. The fixed plate 26 also has multiple lower mounting grooves 32 for installing the convergence bracket 28 evenly arranged along its own circumference. The convergence bracket 28 is rotatably connected to the upper mounting groove 31 and the lower mounting groove 32; the convergence bracket 28 is composed of a first bracket 35 and a second bracket 36, one end of the first bracket 35 is rotatably connected to the lower mounting groove 32, and the other end is rotatably connected to the middle position of the second bracket 36, one end of the second bracket 36 is rotatably connected to the upper mounting groove 31, and the other end is provided with a slot 37 for installing the asynchronous convergence component 13 and the airflow guide plate 14.

[0066] The working principle of the synchronous convergence component 12 is as follows:

[0067] Since the fixed plate 26 is fixed on the X-axis steering block 22, the position of the fixed plate 26 remains unchanged during the convergence process. When the telescopic end of the telescopic rod 30 is extended, the movable plate 27 will be pushed to move outward, thereby driving the convergence bracket 28 to open like an umbrella stand, and the airflow guide plate 14 installed on the convergence bracket 28 will be opened synchronously. Correspondingly, when the telescopic end of the telescopic rod 30 is retracted, the movable plate 27 will be pulled inward, thereby driving the convergence bracket 28 to be retracted, and the airflow guide plate 14 will be retracted synchronously.

[0068] A fan 33 is fixedly mounted on the movable plate 27, and a heating net 34 is fixedly mounted at the air outlet of the fan 33. When the airflow guide plate 14 is in the open state, the air outlet angle and range of the fan 33 can be expanded, the airflow can be evenly dispersed, and the airflow can be avoided from being concentrated in one direction. Therefore, in the daily operation mode of the present application, the airflow guide plate 14 is in the open state, so that the airflow guide plate 14 and the fan 33 can enhance the air flow. In this process, the fan 33 can be fixed at an angle so that the wind direction of the fan 33 is opposite to that of the fan 7 to form a coordination (this solution is more power-saving); the fan 33 can also be kept in a rotating state at all times with the help of the steering assembly 11. In this way, the disturbance range of the surrounding airflow by the fan 33 is expanded (this solution promotes air flow better).

[0069] When the airflow guide plate 14 is in a convergent state, the airflow from the air outlet of the fan 33 will be concentrated in one direction, and the wind force will be strengthened, which can be used to remove dust from the evaporator 2 and the ventilation plate 8.

[0070] There are multiple asynchronous convergence components 13, and each asynchronous convergence component 13 is installed on a corresponding convergence bracket 28. The asynchronous convergence component 13 includes a driving gear 38 and a driven gear 39. The driving gear 38 and the driven gear 39 are meshed with each other and are both rotatably installed in the slot 37. The driving gear 38 is driven by a motor, and the driven gear 39 is fixedly connected to the airflow guide plate 14. By controlling the rotation of the driving gear 38, the driven gear 39 and the airflow guide plate 14 can be driven to rotate, thereby adjusting the opening angle of a single airflow guide plate 14.

[0071] A plurality of airflow guide plates 14 are provided, each of which is mounted on a corresponding asynchronous convergence component 13. The plurality of airflow guide plates 14 are converged to form an air duct 40. An elastic membrane 41 is provided between the airflow guide plates 14 and adjacent airflow guide plates 14 for connection (the elastic membrane 41 may also not be provided).

[0072] The synchronous convergence component 12 can open or converge all the airflow guide plates 14 at the same time, while the asynchronous convergence component 13 is used to adjust the opening angle of a single airflow guide plate 14 .

[0073] The inner diameter of the wind tube 40 gradually decreases toward the end away from the asynchronous convergence component 13. The airflow blown out by the fan 33 passes through the wind tube 40 with a gradually decreasing inner diameter, and the flow rate of the airflow will be significantly accelerated, thereby effectively enhancing the wind force of the fan 33. When performing the defrosting operation, the wind tube 40 can be adjusted to an upward tilted state, so that the warm air blown out by the fan 33 will be deflected upward. At the same time, during the defrosting process, the airflow guide plate 14 at the upper part of the wind tube 40 is opened in time, causing the warm air blown out by the wind tube 40 to present a distribution situation in which the wind force and heat of the upper part gradually weaken, while the wind force of the lower part is strong and the heat is higher. With this wind force and heat distribution mode, the upper part of the wind tube 40 can first effectively preheat and melt the frost layer, and the water produced by the melting will be blown by the strong warm air of the lower part of the wind tube 40 and quickly dried.

[0074] During the entire dynamic process of defrosting, the air duct 40 moves at a constant speed from bottom to top. This movement method can extremely efficiently and timely dry the water flowing downward due to defrosting, fundamentally eliminating the possibility of residual water droplets condensing again, and ensuring the thoroughness and efficiency of the defrosting operation.

[0075] A method for using an air energy heat pump integrated machine, using the above-mentioned air energy heat pump integrated machine, comprising the following steps:

[0076] S1: In the daily operation mode, the fan 33 is turned on and the air flow guide plate 14 is in an open state to enhance air flow;

[0077] S2: During a specific period of time every day, the system switches to the dust removal mode. In the dust removal mode, the airflow guide plate 14 is converged into a wind tube 40, which is directed toward the evaporator 2. Meanwhile, the fan 33 is kept turned on. The wind tube 40 is controlled to move by the regulating module 3 to remove dust from the surface of the evaporator 2.

[0078] S3: After the dust removal on the surface of the evaporator 2 is completed, the air cylinder 40 rotates toward the ventilation plate 8, and the air cylinder 40 is controlled by the adjustment module 3 to move again to remove dust from the ventilation plate 8;

[0079] S4: In winter, when frost is detected on the surface of the evaporator 2 (a defrost probe is installed on the surface of the evaporator 2 to detect whether there is frost), the system switches to the defrost mode.
