Description

Technical Field

After long-term operation, especially in a high humidity environment, frost is easily formed on the evaporator surface of traditional refrigeration equipment.

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] As an innovative refrigeration technology, the environmentally friendly refrigeration equipment that replaces hot fluorine defrosting is suitable for various environmental scenarios that require temperature control, cooling and defrosting. When frost accumulates during system operation, this equipment can effectively solve the problem of unstable hot fluorine flow and pressure control in traditional equipment, ensuring the continuous and efficient operation of the system; refrigeration equipment usually refers to a device that achieves temperature control through circulating refrigerant, which can transfer heat within the system from one place to another, so as to achieve the purpose of lowering the ambient temperature.

[0025] refer to Figure 1-Figure 5 As shown, the embodiment of the present invention provides a thermal fluorine defrosting type environmentally friendly refrigeration device, including: a shell 1, a refrigeration component 2 and an adjustment component 3; The refrigeration assembly 2 includes a condensing assembly 210 fixed inside the housing 1, and the condensing assembly 210 is connected to a cooling assembly 220 through a pipeline; The regulating component 3 includes a pressure regulating component 310 connected to the condensing component 210 through a pipeline, and a separation component 320 connected to the cooling component 220 through a pipeline is arranged above the pressure regulating component 310; The pressure regulating assembly 310 includes: a sliding part 3110, a reset part 3120 and a pipe diameter part 3130. The condensing assembly 210 is connected to the sliding part 3110 through a pipeline. The sliding part 3110 is provided with a pipe diameter part 3130 inside. The reset part 3120 is fixedly connected to the side of the pipe diameter part 3130. The separation component 320 includes: a driving part 3210, a centrifugal part 3220 and a recovery part 3230. The cooling component 220 is connected to the centrifugal part 3220 through a pipeline. The driving part 3210 is provided at the top of the centrifugal part 3220, and the recovery part 3230 is fixedly connected to the bottom of the centrifugal part 3220.

[0026] The refrigeration component 2 is mainly used for compressing and making refrigerant for cooling; the regulating component 3 is used for adjusting the pressure and flow of the refrigerant and recycling it; the condensing component 210 is used for making refrigerant; the cooling component 220 is mainly used for evaporation and heat dissipation; the pressure regulating component 310 is mainly used for adjusting the pressure and flow of the refrigerant; the separation component 320 is used for separating the incompletely vaporized liquid refrigerant and recycling it; The condensing component 210 in the refrigeration component 2 is started to be transported to the cooling component 220 to lower the space temperature. When the frost on the surface of the cooling component 220 is thick, the system switches to the defrosting mode, and the condensing component 210 in the refrigeration component 2 is started again to transport the high-temperature and high-pressure refrigerant gas to the cooling component 220, so that the condensing component 210 will also push the pressure regulating component 310 in the regulating component 3, so that the sliding part 3110 drives the pipe diameter component to slide downward to expand the pipe diameter, and then the high-temperature and high-pressure refrigerant gas flows into the pipe diameter part 3130 through the pipe diameter part The refrigerant is sent to the cooling component 220 for heat release and defrosting. When the evaporated refrigerant returns to the refrigeration component 2, part of the liquid refrigerant is not completely gasified and enters the centrifugal part 3220 of the separation component 320 through the pipeline. Then, the driving part 3210 is started to drive the centrifugal part 3220 to separate the liquid refrigerant from the gaseous refrigerant. Then, the liquid refrigerant flows into the recovery part 3230 under the influence of gravity. At the same time, the gaseous refrigerant enters the recovery part 3230 through the pipeline for preheating, and then flows back into the compressor 211 through the pipeline for reuse. During the refrigeration process, the condensing component 210 in the refrigeration component 2 is started to inhale the low-temperature and low-pressure refrigerant gas, and condense it into a high-pressure liquid, which is then transported through a pipeline to the cooling component 220 to reduce the temperature of the space. When the surface of the cooling component 220 is thickly frosted, the system switches to the defrosting mode, and the condensing component 210 in the refrigeration component 2 is started again to transport the high-temperature and high-pressure refrigerant gas to the cooling component 220 through a pipeline. At the same time, the condensing component 210 will also push the pressure regulating component 310 in the regulating component 3 to move, so that the sliding part 3110 of the pressure regulating component 310 slides, so that the sliding part 3110 drives the pipe diameter component to slide downward to expand the pipe diameter, and then the high-temperature and high-pressure refrigerant gas flows into through the pipe diameter part 3130 In the cooling component 220, the high-temperature and high-pressure refrigerant releases heat and defrosts in the cooling component 220. When the evaporated refrigerant returns to the refrigeration component 2, part of its liquid refrigerant is not completely vaporized, and enters the centrifugal part 3220 of the separation component 320 through the pipeline. Then, the driving part 3210 is started, so that the driving part 3210 drives the centrifugal part 3220 to separate the liquid refrigerant from the gaseous refrigerant. Then, the liquid refrigerant flows into the recovery part 3230 under the influence of gravity. At the same time, the gaseous refrigerant enters the recovery part 3230 through the pipeline for preheating, and then flows back into the compressor 211 through the pipeline for reuse, thereby solving the problem of not being able to control the pressure flow rate of hot fluorine entering the evaporator and recover it, thereby reducing the overall energy efficiency of the system.

[0027] refer to Figure 1 , Figure 4 and Figure 5 As shown, the pipe diameter portion 3130 includes: a first wedge block 3131, a second wedge block 3132, an arc connecting plate 3133 and a sliding tube 3134, the top of the sliding tube 3134 is fixedly connected to the sliding portion 3110, and the sliding tube 3134 is used for the first wedge block 3131 and the second wedge block 3132 to drive the arc connecting plate 3133 to slide through extrusion fit; the first wedge block 3131 and the second wedge block 3132 are in contact with the inclined surface; the pipe diameter portion 3130 also includes: a first arc plate 3135 and a second arc plate 3136, the interior of the first arc plate 3135 is slidably connected to the arc connecting plate 3133, the side of the first arc plate 3135 is provided with a second arc plate 3136, and the second arc plate 3136 is connected to the arc The other end of the connecting plate 3133 is slidably connected; the sliding tube 3134 drives the arc connecting plate 3133 to slide by squeezing with the wedge block, thereby changing the opening size of the tube diameter portion 3130. This design can accurately control the hot fluorine flow in the defrost mode according to actual needs, thereby ensuring efficient operation of the system while avoiding excessive or low pressure in the refrigeration system; the greatest advantage of this technical solution is that the sliding tube 3134 drives the movement of the wedge block and the arc connecting plate 3133, so as to accurately adjust the amount of refrigerant flowing through the pipeline and optimize the pressure control of the system in different operating modes, especially in the defrost mode, which can ensure that the flow and pressure of the hot fluorine reach the optimal state, avoid unstable operation caused by pressure fluctuations, and greatly improve the energy efficiency of the system.

[0028] When the defrost mode is in progress, the sliding tube 3134 slides downward, causing the sliding tube 3134 to drive the first wedge block 3131 to slide downward synchronously, thereby the first wedge block 3131 moves downward to squeeze the second wedge block 3132, causing the second wedge block 3132 to drive the arc connecting plate 3133 to slide in the sliding portion 3110, thereby the arc connecting plate 3133 pushes the first arc plate 3135 and the second arc plate 3136 to slide, causing the first arc plate 3135 and the second arc plate 3136 to slide in opposite directions, thereby increasing the distance between the first arc plate 3135 and the second arc plate 3136, thereby increasing the flow rate of high-temperature and high-pressure liquid refrigerant (hot fluorine) flowing in and reducing the pressure.

[0029] refer to Figure 1 and Figure 4 As shown, the sliding part 3110 includes: a supporting cylinder 3111 and a sliding cylinder 3112, the bottom end of the supporting cylinder 3111 is connected to the pipeline of the condensation component 210, the outer surface of the supporting cylinder 3111 is slidably connected to the sliding cylinder 3112, and the bottom end of the sliding cylinder 3112 is fixedly connected to the sliding tube 3134.

[0030] When the defrost mode is in progress, the condensing assembly 210 drives the sliding cylinder 3112 to slide up and down on the surface of the supporting cylinder 3111, so that the sliding cylinder 3112 drives the sliding tube 3134 to slide up and down synchronously.

[0031] refer to Figure 1 , Figure 4 and Figure 5 As shown, the reset part 3120 includes: a first spring 3121 and a second spring 3122, the side of the arc connecting plate 3133 is fixedly connected to the first spring 3121, and the side of the first spring 3121 is provided with the second spring 3122; through the spring design of the reset part 3120, after the adjustment of the pipe diameter part 3130 is completed, the entire pipeline structure can be quickly returned to the initial state, avoiding component wear or leakage caused by long-term operation. This design not only improves the stability of the system, but also extends the service life of the equipment.

[0032] When the sliding tube 3134 slides downward, the sliding tube 3134 pushes the arc connecting plate 3133 to slide in the support tube 3111, so that the arc connecting plate 3133 squeezes the first spring 3121 and the second spring 3122 during the sliding process. When the sliding tube 3134 slides upward, the sliding tube 3134 no longer pushes the arc connecting plate 3133 to slide in the support tube 3111, so that the first spring 3121 and the second spring 3122 begin to push the arc connecting plate 3133 to slide in the opposite direction and reset through the rebound force.

[0033] refer to Figure 1 and Figure 2 As shown, the driving part 3210 includes: a driving motor 3211 and a rotating rod 3212 . The driving motor 3211 is disposed at the top end of the fixed cylinder 3221 , and the bottom end of the driving motor 3211 is fixedly connected to the rotating rod 3212 .

[0034] When it is necessary to recover the incompletely vaporized liquid refrigerant, the drive motor 3211 is started, so that the drive motor 3211 drives the rotating rod 3212 to rotate, and the rotating rod 3212 drives the centrifugal part 3220 to separate the incompletely vaporized liquid refrigerant.

[0035] refer to Figure 1 and Figure 2 As shown, the centrifugal part 3220 includes: a fixed cylinder 3221 and a rotating fan 3222 , the condensing assembly 210 is connected to the fixed cylinder 3221 by a pipeline, and the rotating fan 3222 is arranged inside the fixed cylinder 3221 .

[0036] During the refrigeration process, the driving motor 3211 drives the rotating fan 3222 to rotate in the fixed cylinder 3221 through the rotating rod 3212, so that the incompletely vaporized liquid refrigerant entering the fixed cylinder 3221 is subjected to the centrifugal force of the rotating fan 3222, and the incompletely vaporized liquid refrigerant begins to separate into liquid refrigerant and gaseous refrigerant.

[0037] refer to Figure 1 , Figure 2 and Figure 3 As shown, the recovery part 3230 includes: a recovery pipe 3231 and a recovery cylinder 3232, the bottom end of the fixed cylinder 3221 is fixedly connected to the recovery pipe 3231, the bottom end of the recovery pipe 3231 is fixedly connected to the recovery cylinder 3232, an air intake pipe 3233 fixed to the top of the fixed cylinder 3221 is arranged above the recovery pipe 3231, and a preheating cylinder 3234 is fixedly connected to the bottom end of the air intake pipe 3233; the preheating cylinder 3234 is arranged opposite to the recovery cylinder 3232; The recovery part 3230 also includes: a preheating tube 3235, a heating coil 3236 and a discharge pipe 3237. A plurality of preheating tubes 3235 are fixedly connected inside the preheating tube 3234, and a heating coil 3236 is sleeved on the surface of the plurality of preheating tubes 3235. A discharge pipe 3237 is arranged below the preheating tube 3235, and the discharge pipe 3237 is located at the bottom end of the preheating tube 3234. The design of the recovery part 3230 includes components such as a recovery tube 3231, a recovery tube 3232 and an air inlet pipe 3233, which can effectively collect and reuse liquid refrigerant that is not completely vaporized. When the system is running, after the incompletely vaporized liquid refrigerant is separated by the centrifugal part 3220 of the separation assembly 320, the liquid refrigerant enters the recovery pipe 3231 due to gravity and finally gathers in the recovery cylinder 3232; this structural design not only ensures the efficient recovery of the liquid refrigerant, but also guides the gaseous refrigerant to the preheating pipe 3235 for heating treatment through the cooperation of the air inlet pipe 3233 and the preheating cylinder 3234. The heating coil 3236 is used to heat the gaseous refrigerant inside the preheating pipe 3235 and preheat it to an appropriate temperature by heat transfer, thereby improving the energy efficiency of the gaseous refrigerant, so that it can be more effectively sucked into and reused by the compressor 211. In this way, the system can reduce the loss of refrigerant and improve the energy efficiency of the entire refrigeration process.

[0038] When the above-mentioned incompletely vaporized liquid refrigerant begins to separate into liquid refrigerant and gaseous refrigerant, the liquid refrigerant flows from the fixed cylinder 3221 into the recovery pipe 3231 under the influence of gravity, and then flows into the recovery cylinder 3232 through the recovery pipe 3231. At the same time, the gaseous refrigerant flows upward into the air intake pipe 3233, and then enters the preheating pipe 3235 in the preheating cylinder 3234 from the air intake pipe 3233. Since the heating coil 3236 is controlled by an external power switch, the external power switch is turned on to make the heating coil 3236 start to heat the preheating pipe 3235. Then the preheating pipe 3235 heats the gaseous refrigerant through heat transfer, thereby achieving preheating, and then re-enters the compressor 211 through the exhaust pipe for reuse.

[0039] The condensation assembly 210 includes: a compressor 211 and a condenser 212, wherein the compressor 211 is disposed inside the housing 1, the compressor 211 is connected to the condenser 212 through a pipeline, and the compressor 211 is connected to the sliding cylinder 3112 through a cylinder 213; The cooling component 220 includes: an exchange tube 221 and a heat sink 222 . The condenser 212 is connected to the exchange tube 221 . The heat sink 222 is sleeved on the surface of the exchange tube 221 .

[0040] During the refrigeration process, the compressor 211 is started to compress the low-temperature and low-pressure refrigerant gas, and compress it into a high-temperature and high-pressure gas. The high-temperature and high-pressure gas then enters the condenser 212, releases heat and condenses into a high-pressure refrigerant liquid, and enters the exchange tube 221 to exchange heat with the air or the medium to be cooled, absorbs heat and evaporates, thereby reducing the temperature of the cooled space and the heat sink 222 will absorb the temperature on the exchange tube 221, thereby reducing the surface temperature of the exchange tube 221 and protecting the exchange tube 221. On the other hand, during the defrosting process, when the high-pressure refrigerant liquid enters the exchange tube 221, it flows into the cylinder 213, causing the cylinder 213 to begin to expand and contract, thereby driving the sliding cylinder 3112 to slide up and down on the surface of the support cylinder 3111, and defrosting by causing the high-temperature and high-pressure refrigerant to release heat when entering the exchange tube 221.

[0041] Working principle: When no refrigeration is performed, the shell 1, the refrigeration assembly 2, the first spring 3121, the second spring 3122 and the pressure regulating assembly 310 are in an initial state, the support cylinder 3111 is slidably connected to the sliding cylinder 3112; the first wedge block 3131 is squeezed and fitted with the second wedge block 3132; the arc connecting plate 3133 is slidably connected to the support cylinder 3111, and the first arc plate 3135 and the second arc plate 3136 are slidably connected to the support cylinder 3111 respectively.

[0042] In the process of refrigeration, in normal refrigeration, the compressor 211 and the condenser 212 are started, so that the compressor 211 starts to compress the low-temperature and low-pressure refrigerant gas, and compresses it into a high-temperature and high-pressure gas, and then the high-temperature and high-pressure gas enters the condenser 212, releases heat and condenses into a high-pressure refrigerant liquid, and when the system is switched to the defrost mode, only the compressor 211 is started to compress the low-temperature and low-pressure refrigerant gas, and compresses it into a high-temperature and high-pressure gas, and then it is transported to the cylinder 213 through the pipeline, so that the cylinder 213 extends to push the sliding cylinder 3112 to slide downward on the surface of the support cylinder 3111, so that the sliding cylinder 3112 drives the sliding tube 3134 to slide downward, and when the sliding tube 3134 slides downward, the sliding tube 31 34 drives the first wedge block 3131 to slide downward synchronously, so that the first wedge block 3131 moves downward to squeeze the second wedge block 3132, so that the second wedge block 3132 drives the arc connecting plate 3133 to slide in the sliding part 3110, and the arc connecting plate 3133 squeezes the first spring 3121 and the second spring 3122 during the sliding process, so that the arc connecting plate 3133 pushes the first arc plate 3135 and the second arc plate 3136 to slide, so that the first arc plate 3135 and the second arc plate 3136 slide in opposite directions, so that the distance between the first arc plate 3135 and the second arc plate 3136 increases, thereby expanding the flow rate of the high-temperature and high-pressure liquid refrigerant (hot fluorine) flowing in to reduce the pressure, and then flows into the exchange tube 221.

[0043] When refrigeration is performed, it is in normal refrigeration mode, and enters the exchange tube 221 to exchange heat with the air or the medium to be cooled, absorbs heat and evaporates, thereby reducing the temperature of the cooled space. In the defrost mode, when the high-pressure refrigerant liquid enters the exchange tube 221, the high-pressure, high-temperature and high-pressure refrigerant in the exchange tube 221 releases heat through heat conduction, so that it defrosts the frost on the surface of the exchange tube 221. At the same time, the heat sink 222 absorbs the temperature on the exchange tube 221, thereby reducing the temperature of the surface of the exchange tube 221 and protecting the exchange tube 221. In normal refrigeration and defrost modes, since the thermal conductivity of the refrigerant in the exchange tube 221 cannot reach 100% whether it absorbs or releases heat, some incompletely vaporized liquid refrigerant will be generated to complete the refrigeration. Refrigeration, when the liquid refrigerant that has not been completely vaporized begins to separate into liquid refrigerant and gaseous refrigerant, the liquid refrigerant flows from the fixed cylinder 3221 into the recovery pipe 3231 due to the influence of gravity, and then flows into the recovery cylinder 3232 through the recovery pipe 3231. At the same time, the gaseous refrigerant flows upward into the air intake pipe 3233, and then enters the preheating pipe 3235 in the preheating cylinder 3234 from the air intake pipe 3233. Since the heating coil 3236 is controlled by an external power switch, turn on the external power switch to make the heating coil 3236 start to heat the preheating pipe 3235. Then the preheating pipe 3235 heats the gaseous refrigerant through heat transfer, thereby achieving preheating, and then re-enters the compressor 211 through the exhaust pipe for reuse.

[0044] When the refrigeration is completed, the compressor 211 and the condenser 212 are turned off, so that the compressor 211 stops sucking the low-temperature and low-pressure refrigerant gas and compressing it into a high-temperature and high-pressure gas, so that the condenser 212 stops releasing the high-temperature and high-pressure gas and condensing it into a high-pressure refrigerant liquid, so that the high-temperature and high-pressure gas cannot push the cylinder 213, so that the cylinder 213 stops driving the sliding cylinder 3112 to slide on the surface of the support cylinder 3111, so that the sliding cylinder 3112 stops driving the sliding cylinder 3112 to push the sliding tube 3134 downward, so that the first spring 3121 and the second spring 3122 begin to slide through the rebound force The arc connecting plate 3133 is pushed to slide in the opposite direction and reset, so that the arc connecting plate 3133 drives the first arc plate 3135 and the second arc plate 3136 to slide relative to each other, so that the distance between the first arc plate 3135 and the second arc plate 3136 is reduced and reset, and at the same time, the power switch between the driving motor 3211 and the outside world is turned off, so that the driving motor 3211 stops driving the rotating fan 3222 to rotate in the fixed cylinder 3221 through the rotating rod 3212, so that the incompletely vaporized liquid refrigerant is no longer recycled, and at the same time, the heating coil 3236 stops heating the gas refrigerant in the preheating tube 3235 for preheating.
