Description

Technical Field

[0001] The invention relates to the technical field of air cooler equipment, and in particular to a hot fluorine defrosting device for an air cooler. Background Art

[0002] Air coolers are devices designed specifically to provide cooling air. They are widely used in HVAC systems, refrigeration, and freezing facilities. They absorb heat from the air by circulating refrigerant, providing cool air to the indoor environment. Thermo-fluorine defrost devices monitor the evaporator temperature to detect frost formation and automatically redirect the refrigerant flow when necessary, directing heat from the compressor to the evaporator to melt the frost, preventing the frost layer from affecting heat exchange efficiency and ensuring efficient operation of the air cooler.

[0003] The existing hot fluorine defrost device for an air cooler is shown in the Chinese application with application number: 202022974828.0: A hot fluorine defrost device for an air cooler, which includes a compressor, a fluorine storage tank, a delivery pipe, an output pipe, a three-way valve, a condenser, a pair of air inlet pipes, an evaporator, a cold discharge pipe, a pair of return pipes and a refrigeration fan; the fluorine in the fluorine storage tank is converted into a high-temperature and high-pressure gas by the compressor, and flows through the condenser and evaporator in turn and finally enters the cold discharge pipe, so that the temperature of the cold discharge pipe increases, thereby achieving the purpose of hot fluorine defrosting.

[0004] In the above-mentioned defrost device, during the refrigeration stage, the low temperature causes the condenser pipe to contract; during the defrost stage, the high temperature causes the condenser pipe to expand. The frequent contraction and expansion will cause the pipe material to be subjected to repeated mechanical stress, increasing the risk of aging and fatigue of the condenser pipe. At the same time, it may cause the pipe to crack or break, increasing the risk of loosening, air leakage or leakage at the joints. Therefore, in the prior art, a temperature sensor is usually added to the condenser pipe to perform real-time temperature detection on the condenser pipe to ensure that the temperature on the condenser pipe is within a certain range, thereby avoiding excessive expansion of the condenser pipe due to excessively high temperature and excessive contraction due to excessively low temperature.

[0005] While detecting the temperature of the radiator pipe through a temperature sensor, the radiator pipe is kept within a certain range. Within this range, the maximum temperature reached by the radiator pipe is limited, and the best defrosting effect of the radiator pipe may not be guaranteed. At the same time, the minimum temperature of the radiator pipe is limited, and the best cooling effect of the air cooler cannot be guaranteed. Therefore, there is room for improvement.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0032] The present embodiment provides a hot fluorine defrost device for an air cooler, which is applied to scenarios where frost forms on the condenser exhaust pipe. In the present embodiment, the structure of the defrost device is improved so that the defrost device can adjust the flow rate of the medium in the condenser exhaust pipe according to the deformation amplitude of the condenser exhaust pipe. At the same time, the temperature of the condenser exhaust pipe is regulated, thereby improving the defrost efficiency and delaying the aging and damage process of the condenser exhaust pipe.

[0033] See also Figure 1-Figure 5 , a cold air machine hot fluorine defrost device provided in this embodiment includes a box body 10, a fluorine storage tank 20, a compressor 30, a cold discharge pipe 40, a measuring component 50, a speed regulating component 60 and a temperature control component. The fluorine storage tank 20, the compressor 30, the cold discharge pipe 40, the measuring component 50, the speed regulating component 60 and the temperature control component are all arranged in the box body 10; the compressor 30 is used to pump the fluorine in the fluorine storage tank 20 into the cold discharge pipe 40, the measuring component 50 is arranged on the cold discharge pipe 40, and is used to detect the deformation amplitude of the cold discharge pipe 40. When the measuring component 50 detects that the cold discharge pipe 40 is at the hot extreme deformation value, the temperature control component lowers the defrost temperature of the cold discharge pipe 40, and the speed regulating component 60 reduces the fluorine delivery speed; when the measuring component 50 detects that the cold discharge pipe 40 is at the cold extreme deformation value, the temperature control component increases the refrigeration temperature of the cold discharge pipe 40, and the speed regulating component 60 increases the fluorine delivery speed.

[0034] Specifically, the formation of frost layer and the change of temperature of the cold exhaust pipe 40 will cause the cold exhaust pipe 40 to deform. The measuring component 50 detects the deformation amplitude of the cold exhaust pipe 40 in real time, reflects whether there is frost accumulation and monitors the deformation amplitude of the cold exhaust pipe 40 at different temperatures. The control terminal 100 determines whether the preset frost layer or frosting degree threshold is reached according to the deformation change value, and decides whether to start the defrosting process; the compressor 30 pumps the fluorine in the fluorine storage tank 20 into the cold exhaust pipe 40. When the fluorine gas flows through the cold exhaust pipe 40, a large amount of heat energy is released to melt the frost layer attached to the pipe wall; the temperature control component adjusts the pressure value and temperature value in the compressor 30 to adjust the output temperature of the fluorine, ensuring that the fluorine gas is at a constant temperature when flowing in the cold exhaust pipe 40 The optimal temperature state can effectively melt the frost layer while avoiding excessive expansion of the radiator pipe 40 caused by excessive temperature, thereby reducing the large deformation of the radiator pipe 40 at lower or higher temperatures; the measuring component 50 continuously monitors the deformation change value of the radiator pipe 40 to ensure that the frost layer is completely melted and avoid overheating, and the control terminal 100 instructs the speed regulating component 60 to adjust the fluorine gas delivery flow rate according to the different deformation amounts of the radiator pipe 40 to improve the defrosting efficiency; after the deformation amplitude returns to the normal range, the control terminal 100 instructs the speed regulating component 60 to adjust the fluorine delivery speed to restore normal working conditions, and the system returns to normal cooling mode. The measuring component 50 continuously monitors the status of the radiator pipe 40 and prepares to detect the next frost formation.

[0035] The present invention monitors the deformation amplitude of the cold exhaust pipe 40 through the measuring component 50, and adjusts the speed regulating component 60 and the temperature control component to perform corresponding operations. When the measuring component 50 detects that the cold exhaust pipe 40 is at the hot extreme deformation value, the temperature control component reduces the defrosting temperature of the cold exhaust pipe 40, so that the expansion amplitude of the cold exhaust pipe 40 is reduced, and the cold exhaust pipe 40 is prevented from generating a large expansion deformation during the defrosting process. At the same time, the speed regulating component 60 reduces the conveying speed of the fluorine, so that the medium 770 in the expanded cold exhaust pipe 40 fully exchanges heat with the frost, which is beneficial to quickly cooling the cold exhaust pipe 40. When the measuring component 50 detects that the cold exhaust pipe 40 is at the cold extreme deformation value, the temperature control component reduces the defrosting temperature of the cold exhaust pipe 40, so that the expansion amplitude of the cold exhaust pipe 40 is reduced, and the cold exhaust pipe 40 is prevented from generating a large expansion deformation during the defrosting process. At the same time, the speed regulating component 60 reduces the conveying speed of the fluorine, so that the medium 770 in the expanded cold exhaust pipe 40 fully exchanges heat with the frost, which is beneficial to quickly cooling the cold exhaust pipe 40. The component increases the refrigeration temperature of the radiator pipe 40, so that the shrinkage of the radiator pipe 40 is reduced, and the radiator pipe 40 is prevented from causing large shrinkage deformation during the refrigeration process of the cold air machine. At the same time, the speed regulating component 60 increases the fluorine delivery speed, so that the shrunken radiator pipe 40 and the medium 770 in the pipe can fully exchange heat, which is conducive to the rapid temperature recovery of the radiator pipe 40. By continuously adjusting the temperature of the medium 770 in the radiator pipe 40, the radiator pipe 40 is in the best defrosting or refrigeration state. At the same time, the deformation of the radiator pipe 40 is controlled, the aging and damage process of the radiator pipe 40 is delayed, the maintenance cost of the radiator pipe 40 is reduced, and the maintenance frequency of the radiator pipe 40 is reduced.

[0036] For example, since the expansion or contraction process of the radiator pipe 40 requires the pipe wall to reach a uniform temperature and overcome the lattice resistance to produce deformation, the deformation of the radiator pipe 40 has a certain hysteresis relative to the change in the pipe wall temperature of the radiator pipe 40. Therefore, during the defrosting process, the medium temperature in the radiator pipe 40 is adjusted to make the radiator pipe 40 at the optimal defrosting temperature. When the radiator pipe 40 reaches the thermal extreme deformation value, the medium temperature and flow rate in the radiator pipe 40 are reduced to reduce its temperature to avoid excessive expansion and deformation, so that the radiator pipe 40 can reach the longest optimal defrosting temperature. time, thereby improving the defrosting effect of the radiator pipe 40 and avoiding excessive deformation of the radiator pipe 40; during the refrigeration process, the temperature of the medium in the radiator pipe 40 is adjusted to make the radiator pipe 40 at the optimal refrigeration temperature, until the radiator pipe 40 reaches the cold pole deformation value, the medium temperature and flow rate in the radiator pipe 40 are increased to increase its temperature to avoid excessive shrinkage deformation, so that the radiator pipe 40 reaches the longest refrigeration time, thereby improving the refrigeration effect of the radiator pipe 40 and avoiding excessive deformation of the radiator pipe 40, and delaying the aging and damage process of the radiator pipe 40.

[0037] See also Figure 2 and Figure 3Furthermore, the measuring component 50 includes an elastic layer 510, a cavity layer 520 and a rigid layer 530. The elastic layer 510 is covered on the radiator pipe 40, the rigid layer 530 is arranged on the outside of the elastic layer 510, and the cavity layer 520 is arranged between the elastic layer 510 and the rigid layer 530. A plurality of deformation capsules 521 are arranged at equal angles in the cavity layer 520, and adjustment capsules 522 are arranged on both sides of the deformation capsule 521. The deformation capsule 521 is filled with a medium 770. A first channel 523 is arranged between the deformation capsule 521 and the adjustment capsule 522. The deformation capsule 521 and the adjustment capsule 522 are both elastic structures. Specifically, when high-temperature fluorine is delivered to the radiator tube 40, the radiator tube 40 expands due to the heat, squeezing the elastic layer 510 toward the rigid layer 530. This compresses the cavity layer 520, and the medium 770 filled in the deformable capsule 521 is expelled from the elastic layer 510 through the first channel 523 into the regulating capsule 522. When the cavity layer 520 is squeezed to the minimum compression space, the medium 770 in the regulating capsule 522 is discharged outward. When frost forms on the radiator tube 40, the temperature of the radiator tube 40 decreases, causing the tube to contract, causing the elastic layer 510 to contract away from the rigid layer 530. The cavity layer 520 expands, the deformable capsule 521 expands, and the medium 770 filled in the regulating capsule 522 flows into the deformable capsule 521 through the first channel 523. When the cavity layer 520 expands to the maximum expansion space, the external medium 770 flows into the regulating capsule 522. The minimum compression space and the maximum expansion space are preset values. Through the action of the deformation capsule 521 and the medium 770, the deformation amplitude of the radiator pipe 40 is quantified, and the temperature change and frosting condition of the radiator pipe 40 are directly reflected by feeding back the deformation degree of the radiator pipe 40, so that the control terminal 100 can more accurately monitor the frosting degree of the radiator pipe 40 to avoid blind or excessive operation; more precise defrost control is achieved, such as adjusting the defrost temperature and time according to different frosting degrees to ensure that the frost layer is completely melted without leaving any residue, thereby improving the refrigeration efficiency and, at the same time, avoiding aging caused by excessive deformation of the radiator pipe 40.

[0038] See also Figure 4Furthermore, the hot fluorine defrost device also includes a trigger assembly 70, which includes a liquid reservoir 710, a spring 720, a locking seat 730, a guide rod 740, and a trigger rod 750; the locking seat 730 is connected to the bottom surface of the liquid reservoir 710 through the spring 720 and slides along the liquid reservoir 710, and a liquid storage cavity 760 is provided between the bottom of the locking seat 730 and the liquid reservoir 710, and the liquid storage cavity 760 is filled with a medium 770. The liquid storage cavity 760 is connected to the regulating The sac 522 is connected; a guide rail 780 is provided on the locking seat 730, one end of the guide rod 740 is hinged to the liquid reservoir 710, and the other end rotates clockwise or counterclockwise along the guide rail 780, and a through hole 790 is provided on the top of the liquid reservoir 710, one end of the trigger rod 750 is fixed to the locking seat 730, and the other end slides in the through hole 790, and the trigger rod 750 is electrically connected to the control terminal 100, and is used to trigger different operating states of the speed regulation component 60 and the temperature control component. Specifically, the medium 770 in the liquid storage chamber 760 and the regulating capsule 522 flows freely. When the regulating capsule 522 is squeezed, the medium 770 in the regulating capsule 522 is discharged into the liquid storage chamber 760, and the medium 770 in the liquid storage chamber 760 increases; when the regulating capsule 522 is relaxed, the medium 770 in the liquid storage chamber 760 flows into the regulating capsule 522, and the medium 770 in the liquid storage chamber 760 decreases; when the medium 770 in the liquid storage chamber 760 increases or decreases, the locking seat 730 slides along the liquid reservoir 710. During the sliding process of the locking seat 730, one end of the guide rod 740 is hinged to the liquid reservoir 710, and the other end slides in the guide rail 780; the trigger rod 750 is electrically connected to the control terminal 100. When the guide rod 740 slides to different positions, different defrost states are triggered, so that the control terminal 100 can adjust the defrost temperature and rate according to the real-time state of the condenser pipe 40, thereby realizing precise control of the defrost process.

[0039] See also Figure 4Furthermore, the guide rail 780 is a closed structure connected end to end, with a first limit point 781 provided at the bottom of the guide rail 780 and a second limit point 782 provided at the top of the guide rail 780. The end of the guide rod 740 is located at the first limit point 781, and the trigger rod 750 triggers the first state; the end of the guide rod 740 slides from the first limit point 781 to the second limit point 782, and the trigger rod 750 slides along the first direction and triggers the second state; the end of the guide rod 740 is located at the second limit point 782, and the trigger rod 750 triggers the third state; the end of the guide rod 740 slides from the second limit point 782 to the first limit point 781, and the trigger rod 750 slides along the second direction and triggers the fourth state. Specifically, when the cavity layer 520 enters the compression state from the initial state, the end of the guide rod 740 is located at the second limit point 782, and the trigger rod 750 triggers the third state; when the cavity layer 520 is compressed to the minimum compression space, the end of the guide rod 740 slides from the second limit point 782 to the first limit point 781, and the trigger rod 750 slides along the second direction and triggers the fourth state; when the cavity layer 520 enters the relaxation state from the initial state, the end of the guide rod 740 is located at the first limit point 781, and the trigger rod 750 triggers the first state; when the cavity layer 520 relaxes to the maximum relaxation space, the end of the guide rod 740 slides from the first limit point 781 to the second limit point 782, and the trigger rod 750 slides along the first direction and triggers the second state. According to the deformation of the radiator pipe 40, different defrost states are triggered to achieve defrost intensity level classification. The most suitable defrost strategy is automatically selected for different frosting environments to ensure continuous and stable operation of the equipment. At the same time, a mechanical structure is used to limit state switching to effectively avoid the impact of electronic failures and improve system reliability.

[0040] See also Figure 5 Furthermore, a delivery pipe 80 is arranged between the cold discharge pipe 40 and the compressor 30, and the speed regulating assembly 60 is arranged in the delivery pipe 80. The speed regulating assembly 60 includes a fixed block 610, a sliding block 620 and a driving assembly 630. The fixed block 610 is fixed in the delivery pipe 80, and the end surfaces of the fixed block 610 and the sliding block 620 that are close to each other are inclined and parallel. The driving assembly 630 is used to drive the sliding block 620 to move in a direction close to or away from the fixed block 610. Specifically, the fixed block 610 and the sliding block 620 are both arranged in the delivery pipe 80 along the axial direction of the delivery pipe 80. Since the end faces of the sliding block 620 and the fixed block 610 are arranged in parallel, when the sliding block 620 moves toward the fixed block 610, the channel between the two becomes narrower, thereby narrowing the fluorine delivery channel and reducing the fluorine delivery rate; when the sliding block 620 moves in the direction away from the fixed block 610, the channel between the two becomes larger, and the fluorine delivery rate is increased, thereby realizing the adjustment of the fluorine delivery rate; by dynamically adjusting the fluorine gas delivery rate, it is ensured that rapid defrosting is achieved under different frosting conditions, while avoiding excessive heating or energy waste.

[0041] Furthermore, when in the first state, the speed regulation component 60 is instructed to perform a deceleration operation, and the temperature control component is instructed to perform a cooling operation; when in the second state, the speed regulation component 60 is instructed to perform a deceleration operation, and the temperature control component is not triggered; when in the third state, the speed regulation component 60 is instructed to perform an acceleration operation, and the temperature control component is instructed to perform a heating operation; when in the fourth state, the speed regulation component 60 is instructed to perform an acceleration operation, and the temperature control component is not triggered.

[0042] When the trigger lever 750 slides in the first direction, the sliding block 620 is driven to slide toward the fixed block 610. When the trigger lever 750 slides in the second direction, the sliding block 620 is driven to slide away from the fixed block 610. Specifically, when the trigger lever 750 slides in the first direction, the defrost device is in the second state, and the speed regulating assembly 60 is instructed to perform a deceleration operation. At this time, the sliding block 620 moves toward the fixed block 610. When the trigger lever 750 slides in the second direction, the defrost device is in the fourth state, and the sliding block 620 moves away from the fixed block 610. The trigger rod 750 slides in two directions, driving the sliding block 620 to move axially, corresponding to different defrost states respectively. The defrost force is dynamically adjusted according to the actual state of the pipeline to avoid excessive or insufficient defrost force. Through the synchronous movement of the trigger rod 750 and the sliding block 620, the input flow rate of fluorine is adaptively adjusted according to the deformation amplitude of the radiator pipe 40, the flow rate is finely controlled, and the speed regulation component 60 responds quickly and stably, thereby improving the operating efficiency of the equipment; the bidirectional sliding of the trigger rod 750 realizes multi-stage state switching compactly and reliably.

[0043] See also Figure 2 and Figure 3 Furthermore, a power-assisting balloon 511 is provided on the elastic layer 510 , and the power-assisting balloon 511 is arranged opposite to the deformation balloon 521 . Specifically, the boosting balloon 511 is made of a silicone rubber balloon, which has a certain linear thermal expansion coefficient. When the cold radiator 40 expands due to heat, the boosting balloon 511 expands accordingly. When the cold radiator 40 contracts due to cooling, the boosting balloon 511 contracts accordingly. When the cold radiator 40 expands due to heat and causes the elastic layer 510 to deform, the boosting balloon 511 expands and concentrates force on the deformation capsule 521, which can cause the deformation capsule 521 to produce a more obvious compression deformation. When the cold radiator 40 contracts due to cooling and causes the elastic layer 510 to deform, the boosting balloon 511 contracts, reducing the force on the deformation capsule 521, causing the deformation capsule 521 to produce a more obvious expansion deformation. The deformation capsule 521 can more sensitively reflect the deformation changes of the elastic layer 510, thereby improving the accuracy of deformation measurement. At the same time, the boosting balloon 511 improves the response sensitivity and accuracy of the deformation capsule 521 by exerting concentrated force.

[0044] See also Figure 2 and Figure 3 Furthermore, the deformation capsule 521 is ellipsoidal in shape, and the two ends of the deformation capsule 521 along the long axis direction are respectively in contact with the top and bottom surfaces of the cavity layer 520. Specifically, the ellipsoidal structure has a larger elastic deformation space, especially in the long axis direction, and can adapt to a larger deformation amplitude. Compared with the spherical shape, the ellipsoidal shape has a greater expansion and contraction ability in the long axis direction, which helps to capture the slight or severe deformation of the radiator pipe 40; at the same time, the ellipsoidal design can balance the stress concentration points, reduce local stress concentration, and avoid material fatigue or damage caused by stress concentration; the two ends are in contact with the top and bottom surfaces of the cavity layer 520, ensuring that when the deformation capsule 521 is deformed, its deformation state can be accurately transmitted to the cavity layer 520, which helps to obtain the most realistic deformation information of the cavity layer 520.

[0045] See also Figure 1 Furthermore, one end of the cold discharge pipe 40 away from the delivery pipe 80 is connected to the evaporator 90. Specifically, the recovered heat energy can be used to heat or preheat the evaporator 90, thereby reducing the dependence of the refrigerant heat pump system on the compressor 30 and other energy sources and reducing energy consumption. In the air cooler system, the function of the cold discharge pipe 40 is mainly to absorb or release heat by the gas flowing through the pipe to regulate the temperature. Under certain working conditions, excess heat energy will be absorbed in the pipe. If this heat energy can be effectively recovered, the external energy input of the system can be reduced and the overall energy efficiency can be improved. By connecting the far end of the cold discharge pipe 40 to the evaporator 90, the system can transfer the waste heat to the evaporator 90, and use the refrigerant or auxiliary heating system in the evaporator 90 to recycle the heat energy to avoid waste; the excess heat of the cold discharge pipe 40 is recovered and reused, for example, to preheat the air in the evaporator 90, heat the ventilation path or preheat the air, thereby improving energy utilization efficiency.

[0046] In summary, the hot fluorine defrost device provided in this embodiment has the advantages of improving the control accuracy of the defrost function and delaying the aging and damage process of the radiator pipe 40.
