Description

Technical Field

[0002] Frosting is a common problem when operating in low-temperature and high-temperature environments. When the evaporator surface temperature of the air source heat pump is lower than the air dew point temperature, the water vapor in the air will condense into small water droplets on the evaporator surface. As the temperature drops further, these water droplets will freeze and gradually form a frost layer. The frosting process includes stages such as droplet condensation, droplet freezing, frost layer formation, and frost layer completely covering the surface.

[0003] The existing low-temperature air source heat pump system has low energy efficiency, unstable operation, easy frost, and incomplete gas-liquid separation. It is impossible to optimize the refrigerant circulation path, enhance the gas-liquid separation effect, use waste heat for insulation and heating, and prevent frost.

[0028] 3. In the present invention, a rotating mechanism is provided so that the arc block on the T-shaped rod is squeezed so that the hemispherical block located on the upper part can impact the porous mesh, so that the liquid refrigerant retained in the porous mesh can fall down, and the landing process of the droplets attached to the porous mesh can be accelerated, so that the adhesion between the droplets and the filaments is weakened, and the droplets are more likely to fall off the filaments and fall faster, thereby improving the efficiency of gas-liquid separation, and increasing the collision frequency between the droplets and the porous mesh, so that more droplets can be captured and separated from the airflow, thereby improving the capture efficiency of the porous mesh.

[0029] 4.

[0042] Embodiment 1, as Figure 1 and Figure 2 As shown, a low-temperature air source heat pump dry adsorption type intelligent frost-free control system comprises:

[0043] The compressor 1 is arranged inside the device and is used as a refrigerant compression component to compress the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant;

[0044] Connecting pipes, including connecting pipe 1 12, connecting pipe 2 13, connecting pipe 3 14, connecting pipe 4 15, connecting pipe 5 16 and connecting pipe 6 22, for connection;

[0045] A gas-liquid separator 2, which is connected to the compressor 1 through a connecting pipe 12, is arranged inside the device and serves as a gas-liquid separation component for separating gaseous and liquid refrigerants;

[0046] Evaporator 1 3, which is connected to the gas-liquid separator 2 through a pipeline, is arranged inside the equipment and is used for heat exchange between the refrigerant and the ambient air, absorbing heat from the air and evaporating the liquid refrigerant into a gaseous state;

[0047] Condenser 4, which is connected to compressor 1 through connecting pipe 2 13, is arranged inside the device and is used to transfer heat in the gaseous refrigerant to surrounding air or water, so that the gaseous refrigerant is cooled and condensed into liquid;

[0048] Liquid reservoir 6, liquid reservoir 6 is connected to evaporator 3 through a pipeline, liquid reservoir 6 is connected to evaporator 3 through connecting pipe 24 15, which is arranged inside the equipment and is used to store and stabilize the supply of liquid refrigerant;

[0049] Economizer 7, economizer 7 is connected to liquid storage 6 through pipelines, economizer 7 is connected to compressor 1 through connecting pipe 5 16, economizer 7 is connected to condenser 4 through connecting pipe 6 22, economizer 7 is connected to connecting pipe 6 22 through connecting pipe 3 14, which is arranged inside the equipment and is used for heat exchange between high-temperature refrigerant and low-temperature liquid refrigerant;

[0050] The fan 10 is fixedly mounted at one end of the evaporator 3 and is arranged inside the device for sucking air;

[0051] Evaporator 2 11, evaporator 2 11 is fixedly installed between evaporator 1 3 and condenser 4, and is arranged inside the equipment to improve heat exchange efficiency;

[0052] The separation component 9, a part of which is arranged in the inner cavity of the gas-liquid separator 2, and the other part of which is arranged on the outer surface of the condenser 4, is used for heat preservation and separation.

[0053] For further information, see Figure 1 In this embodiment, a sensor 17 is fixedly installed on the outer surface of the connecting pipe 13, a sensor 2 18 is fixedly installed on the outer surface of the connecting pipe 12, a sensor 3 19 is fixedly installed on the outer surface of the connecting pipe 14, a sensor 4 20 is fixedly installed on the outer surface of the connecting pipe 5 16, a sensor 5 21 is fixedly installed on the outer surface of the evaporator 1 3, an electronic expansion valve 1 5 is fixedly installed on the inner surface of the connecting pipe 4 15, and an electronic expansion valve 2 8 is fixedly installed on the inner surface of the connecting pipe 3 14.

[0054] During the implementation of this embodiment, a gaseous low-temperature and low-pressure refrigerant is placed inside the compressor 1, and the low-pressure and low-temperature gaseous refrigerant is compressed into a high-temperature and high-pressure gaseous refrigerant, and enters the condenser 4 through the connecting pipe 2 13. In the condenser 4, the refrigerant releases heat and is converted into a liquid refrigerant. The liquid refrigerant enters the economizer 7 through the connecting pipe 6 22, exchanges heat with part of the low-temperature refrigerant, and is stored in the liquid reservoir 6 to maintain the balance of the liquid refrigerant. After being reduced in pressure by the electronic expansion valve 1 5, the refrigerant enters the evaporator 3 and the connecting pipe 4 15, exchanges heat with the outside world, completes the refrigeration process, and becomes a gaseous refrigerant and enters the gas-liquid separator 2. After being separated by the separation component 9, the gaseous refrigerant returns to the compressor 1 through the connecting pipe 1 12, and the liquid refrigerant is stored in the gas-liquid separator 2 and waits for the next cycle.

[0055] In the auxiliary circuit, the refrigerant passes through the electronic expansion valve 2 8 and the connecting pipe 3 14 and then enters the economizer 7 for secondary heat exchange. The vaporized refrigerant returns to the compressor 1 through the connecting pipe 5 16 to start a new cycle. The temperature of the condenser 4 is controlled to prevent frost. The fan 10 allows dry air to flow through the condenser 4 to remove moisture and avoid the formation of frost. The sensor 5 21 monitors the humidity. When it is lower than the dew point, it will send a signal to adjust the frequency of the compressor 1, increase the dehumidification capacity of the condenser 4, and ensure frost-free operation under different environments.

[0056] The above-mentioned sensor 1 17, sensor 2 18, sensor 3 19, sensor 4 20 and sensor 5 21 are all mature technical means and conventional designs in the prior art, among which sensor 1 17, sensor 2 18, sensor 3 19 and sensor 4 20 are temperature sensors, and sensor 5 21 is a humidity sensor. This scheme will no longer elaborate on their internal structures, principles and connection methods.

[0057] The compressor 1, gas-liquid separator 2, evaporator 3, condenser 4, electronic expansion valve 5, liquid storage tank 6, economizer 7, electronic expansion valve 2 8 and fan 10 mentioned above are all mature technical means and conventional designs in the prior art, and this scheme will no longer elaborate on their internal structure, principle and connection method.

[0058] The condenser 4 mentioned above is always kept at a temperature higher than the ambient temperature during use in this solution.

[0059] Specifically, in order to capture the tiny liquid refrigerant in the gas phase, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10In this embodiment, the separation component 9 includes a partition 91 fixedly connected to the inner surface of the gas-liquid separator 2, a spiral mechanism 92 is provided on the inner surface of the gas-liquid separator 2, an air separation mechanism 93 is provided on the inner surface of the gas-liquid separator 2 above the spiral mechanism 92, a capture mechanism 94 is provided on the inner surface of the gas-liquid separator 2 above the air separation mechanism 93, a rotating mechanism 95 is provided at the lower end of the partition 91, a reflux mechanism 96 is provided on the inner surface of the partition 91, and a heat preservation mechanism 97 is provided on the outer surface of the condenser 4.

[0060] For further information, see Figure 3 and Figure 4 In this embodiment, the spiral mechanism 92 includes a cylinder 921 fixedly connected to the inner surface of the partition 91, a spiral plate 922 fixedly connected to the outer surface of the cylinder 921, a plurality of blocking blocks 923 fixedly connected to the outer surface of the spiral plate 922 at spirally equidistant distributions, and a connecting pipe 924 fixedly connected to the inner surface of the partition 91.

[0061] During the implementation process, the gas-liquid mixed refrigerant after absorbing heat through the evaporator 3 enters the inner cavity of the gas-liquid separator 2 through the pipeline, and then the gas-liquid mixed refrigerant falls on the spiral plate 922 under the action of gravity. Since the spiral plate 922 is spirally designed, the gas-liquid mixed refrigerant will flow downward along the spiral of the spiral plate 922. Under the action of the blocking block 923, the gas-liquid mixed refrigerant can be blocked and impacted, which increases the contact time between the gas-liquid mixed refrigerant and the inner wall of the gas-liquid separator 2, so that the liquid refrigerant can be better separated from the gaseous refrigerant. At the same time, the impact of the blocking block 923 can further promote gas-liquid separation, help the liquid refrigerant to settle to the bottom, and the gaseous refrigerant is guided to rise, thereby achieving a more effective gas-liquid separation process.

[0062] For further information, see Figure 3 , Figure 5 and Figure 6 In this embodiment, the air distribution mechanism 93 includes a circular plate 931 fixedly connected to the inner surface of the gas-liquid separator 2, a plurality of cylinders 932 are fixedly connected to the inner surface of the circular plate 931, a plurality of cylinders 932 are fixedly connected to the inner surfaces of the plurality of cylinders 932, a plurality of pull ropes 934 are slidably connected to the inner surfaces of the plurality of cross blocks 933, a plurality of pull ropes 934 are fixedly connected to the lower ends of the plurality of pull ropes 934 to the fixed blocks 935, a plurality of pull ropes 934 are fixedly connected to the upper ends of the pull ropes 937, a plurality of springs 936 are sleeved on the outer surfaces of the plurality of pull ropes 934, and the two ends of the plurality of springs 936 are respectively fixedly connected to the upper end of the fixed block 935 and the lower end of the cross block 933.

[0063] For further information, see Figure 2 and Figure 7In this embodiment, a plurality of slide rods 942 are sleeved with springs 944 on their outer surfaces, and the two ends of the plurality of springs 944 are respectively fixedly connected to the upper end of the lower hemispherical block 943 and the lower end of the annular plate 941, and the inner surface of the annular plate 941 is fixedly connected to a porous mesh 945.

[0064] During implementation, the gaseous refrigerant will enter the inner cavity of the cylinder 932 during its upward movement. When the pressure of the accumulated gaseous refrigerant is greater than the gravity of the ball 937, the gaseous refrigerant will push the ball 937 to move upward, causing the pull rope 934 to slide on the inner surface of the cross block 933, and the spring 936 to be in a compressed state. Then, the outer surface of the ball 937 moves away from the upper end of the cylinder 932, so that the upper end of the cylinder 932 is opened, and the gaseous refrigerant can be diverted by the shape of the outer surface of the ball 937. The diverted gaseous refrigerant will move upward through the porous mesh 945. The porous mesh 945 can effectively capture the fine liquid refrigerant particles in the gaseous refrigerant under the action of the pores, thereby achieving finer gas-liquid separation, reducing the liquid refrigerant entering the gaseous refrigerant flow path, and improving the separation efficiency.

[0065] The porous mesh 945 mentioned above is a mature wire mesh demister in the prior art. In this solution, its function of capturing fine liquid refrigerant particles in the gaseous refrigerant by using its high porosity is utilized, and its internal structure and principle are not further elaborated.

[0066] Embodiment 2: In order to vibrate the captured liquid refrigerant, refer to Figure 2 ,and Figure 7 In this embodiment, the capture mechanism 94 includes a circular plate 941 fixedly connected to the inner surface of the gas-liquid separator 2, and a plurality of slide rods 942 are slidably connected to the inner surface of the circular plate 941, and a hemispherical block 943 is fixedly connected to both ends of the plurality of slide rods 942.

[0067] For further information, see Figure 3 and Fig. 9 In this embodiment, the rotating mechanism 95 includes a shell 951 fixedly connected to the lower end of the partition 91, a water impeller 952 is rotatably connected to the inner surface of the shell 951, a collecting frame 955 is fixedly connected to one end of the spiral plate 922, a spiral tube 956 is fixedly connected to the inner surface of the collecting frame 955, and the upper end of the water impeller 952 is fixedly connected to a T-shaped rod 953 rotatably connected to the cylinder 921, and the lower end of the water impeller 952 is fixedly connected to a stirring plate 954.

[0068] During the implementation process, the liquid refrigerant flowing downward through the spiral plate 922 will enter the inner cavity of the collecting frame 955. The flow rate of the liquid refrigerant will be accelerated and the flow direction will be changed under the action of the spiral tube 956, so that the liquid refrigerant can impact the water impeller 952, thereby driving the arc block on the T-shaped rod 953 to squeeze the hemispherical block 943. The spring 2 944 is in a compressed state, pushing the slide bar 942 to move upward intermittently, and at the same time, the hemispherical block 943 located at the upper part can impact the porous mesh 945, so that the liquid refrigerant retained in the porous mesh 945 can fall, which can accelerate the landing process of the droplets attached to the porous mesh 945, and weaken the adhesion between the droplets and the filaments, so that the droplets are more likely to fall off the filaments and accelerate their falling, thereby improving the efficiency of gas-liquid separation, and increasing the collision frequency between the droplets and the porous mesh 945, so that more droplets can be captured and separated from the airflow, thereby improving the capture efficiency of the porous mesh 945.

[0069] Secondly, the rotation of the water impeller 952 can also drive the stirring plate 954 to rotate, so that the stirring plate 954 stirs the separated hydraulic refrigerant, which helps to improve the uniformity of the liquid refrigerant, avoid liquid aggregation or precipitation, and ensure the fluidity and stability of the refrigerant inside the gas-liquid separator 2, thereby promoting more effective gas-liquid separation. At the same time, stirring can also increase the contact area between liquid and gas, further improving the separation efficiency.

[0070] The water impeller 952 mentioned above is a mature hydrodynamic part in the prior art. In this solution, the flow of liquid is used to drive the water impeller 952 to rotate, and its internal structure, connection method and principle are not further explained.

[0071] For further information, see Figure 3 and Fig.10 In this embodiment, the reflux mechanism 96 includes a connecting tube 961 that passes through the lower end of the partition 91 and extends to the upper end of the circular plate 931 and is fixedly connected. A conical tube 962 is fixedly connected to the upper inner surface of the connecting tube 961. A round hole tube 963 is fixedly connected to the inner surface of the conical tube 962. A round block 964 is slidably connected to the inner surface of the round hole tube 963. A buoyancy ball 965 is fixedly connected to the upper end of the round block 964 through a connecting rope.

[0072] During the implementation process, the vibrating and falling liquid refrigerant can fall on the upper end of the circular plate 931. As the horizontal plane of the liquid refrigerant increases, the buoyancy ball 965 will gradually move upward under the action of buoyancy, so that the buoyancy ball 965 will pull the round block 964 upward through the connecting rope, so that the round block 964 cannot block the round hole on the round hole tube 963. At this time, the liquid refrigerant can enter the bottom of the inner cavity of the gas-liquid separator 2 under the action of the round hole tube 963 and the connecting tube 961.

[0073] Embodiment 3: In order to heat the gaseous refrigerant, please refer to Figure 2 ,and Figure 8 In this embodiment, the heat preservation mechanism 97 includes a heat-conducting ring 971 fixedly connected to the outer surface of the condenser 4, a heat-conducting rod 973 is fixedly connected to the outer surface of the heat-conducting ring 971, a heat-conducting pipe 972 fixedly connected to the heat-conducting rod 973 is fixedly installed on the outer surface of the connecting pipe 12, and a heat-conducting cloth 974 is fixedly installed on the outer surfaces of the heat-conducting ring 971, the heat-conducting rod 973 and the heat-conducting pipe 972.

[0074] During the implementation process, the temperature of the condenser 4 is transferred to the heat pipe 972 through the heat conductive ring 971 and the heat conductive rod 973 under the action of heat transfer. Since the heat conductive pipe 972 is fixedly installed on the outer surface of the connecting pipe 12, the temperature of the connecting pipe 12 can be maintained, and the separated gaseous refrigerant is kept warm or heated, providing better premise adjustment for the subsequent reuse of the compressor 1, preventing the gaseous refrigerant from condensing due to low temperature during transportation, ensuring that the gaseous refrigerant maintains an appropriate temperature, so as to facilitate the efficient operation of the subsequent compressor 1, and can also improve the thermal efficiency of the refrigerant, optimize the performance of the compressor 1, and ensure its stability and reliability.

[0075] The heat pipe 972, heat ring 971 and heat rod 973 mentioned above are all mature heat transfer technical means and conventional designs in the prior art. This solution utilizes their good heat transfer capabilities and will not further elaborate on their internal structure, principles and materials.

[0076] The above-mentioned insulation cloth 974 is a mature insulation technical means and conventional design in the prior art, and its internal structure, principle and material will not be elaborated again.

[0077] Working process: When in use, a low-temperature and low-pressure refrigerant in a gaseous state is put into the compressor 1, and the low-pressure and low-temperature gaseous refrigerant is compressed into a high-temperature and high-pressure gaseous refrigerant, and enters the condenser 4 through the connecting pipe 2 13. In the condenser 4, the refrigerant releases heat and turns into a liquid refrigerant. The liquid refrigerant enters the economizer 7 through the connecting pipe 6 22, exchanges heat with part of the low-temperature refrigerant, and the refrigerant is stored in the liquid storage 6 to maintain the balance of the liquid refrigerant. After being reduced in pressure by the electronic expansion valve 15, it enters the evaporator 3 and the connecting pipe 4 15 to exchange heat with the outside world, completing the refrigeration process. It becomes gaseous refrigerant and enters the gas-liquid separator 2. Through the cooperation of the spiral mechanism 92, the air distribution mechanism 93 and the capturing mechanism 94, the fine liquid refrigerant particles in the gaseous refrigerant are captured. Then, under the action of the rotating mechanism 95, the captured particles are vibrated and dropped. Then, they flow to the lower part of the inner cavity of the gas-liquid separator 2 through the reflux mechanism 96. After separation, the gaseous refrigerant enters the connecting pipe 12. Under the action of the insulation mechanism 97, the gaseous refrigerant is insulated and finally returns to the compressor 1. The liquid refrigerant is stored in the gas-liquid separator 2 and waits for the next cycle.

[0078] In the auxiliary circuit, the refrigerant passes through the electronic expansion valve 2 8 and the connecting pipe 3 14 and then enters the economizer 7 for secondary heat exchange. The vaporized refrigerant returns to the compressor 1 through the connecting pipe 5 16 to start a new cycle. The temperature of the condenser 4 is controlled to prevent frost. The fan 10 allows dry air to flow through the condenser 4 to remove moisture and avoid the formation of frost. The sensor 5 21 monitors the humidity. When it is lower than the dew point, it will send a signal to adjust the frequency of the compressor 1, increase the dehumidification capacity of the condenser 4, and ensure frost-free operation under different environments.
