Description

Technical Field

[0001] This invention belongs to the field of refrigeration equipment technology, specifically relating to a refrigeration device and refrigeration method that recycles condensate. Background Technology

[0002] Condensate recovery and utilization technology is an environmentally friendly technology that has received widespread attention in refrigeration equipment in recent years. During operation, refrigeration equipment absorbs heat from the air, resulting in the generation of condensate. Traditionally, this condensate was often directly discharged to the outside, wasting water resources and increasing energy consumption and environmental pollution risks. With technological advancements, condensate recovery and utilization systems are gradually becoming standard features in modern refrigeration equipment, especially in large commercial buildings, industrial refrigeration systems, and applications with high environmental requirements. The efficient utilization of condensate has become a crucial means of improving energy efficiency and reducing environmental burden.

[0003] Although condensate recycling helps save energy, long-term use can bring some problems. First, the acidity of existing condensate gradually increases due to repeated reactions with carbon dioxide during circulation, leading to pipe corrosion and affecting normal pipe flow. Second, untreated condensate is prone to bacterial and microbial growth over a long period of time, and minerals in the condensate may deposit to form scale, causing pipe scaling, affecting refrigeration efficiency and increasing energy consumption, thereby reducing the refrigeration performance of refrigeration equipment. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a refrigeration device and refrigeration method that recycles condensate.

[0005] The technical solution adopted to solve the above technical problems is: a refrigeration device for recycling condensate, including a condenser tank and a circulation chamber disposed at one end thereof, a partition chamber is provided between the condenser tank and the circulation chamber, and a circulation processing mechanism is provided in the circulation chamber;

[0006] The circulation treatment mechanism includes an adjustment component and a decomposition component, which are used to control the swirling direction of the circulating condensate and to decompose and adsorb the condensate. The decomposition component is equipped with an acceleration component, which, under the control of the adjustment component, achieves descaling of the pipeline.

[0007] The condenser is equipped with a compressor, liquid receiver, dryer filter and evaporator connected to each other at the front end.

[0008] Furthermore, the decomposition component includes a constriction section, a throat, and a diffusion section disposed within the circulation cavity, wherein both the constriction section and the diffusion section are T-shaped, and the diffusion section is longer than the constriction section.

[0009] Furthermore, the adjusting assembly includes a hydraulic cylinder and a cylinder in a cylinder and shaft that rotate at the end of its piston rod, the hydraulic cylinder being fixed to the top of the circulation chamber.

[0010] Furthermore, a support is provided inside the contraction section, and a support cylinder is rotatably mounted on the support. Rotating columns arranged in a ring are provided on the support cylinder. A first connecting rod rotatably tilted downwards is mounted on the cylinder wall of the cylinder and shaft, and a second connecting rod fixed to one end of the rotating column is rotatably mounted at the other end of the first connecting rod. A blade is provided at the other end of the second connecting rod.

[0011] Furthermore, the speed-increasing component includes a rotating shaft fixed to the bottom of the support cylinder, and a group of support rods are fixed on the rotating shaft. A segmented spiral blade that fits the throat is fixed to the other end of the support rod.

[0012] Furthermore, the circulation chamber is provided with a cooling component for reducing the temperature of the condensate. The cooling component includes transversely evenly arranged tubes disposed on the contraction section and the diffusion section. A fan and a vent are respectively disposed before and after the circulation chamber.

[0013] Furthermore, the other end of the arrangement tube is connected to a circulation pipe separated by a partition cavity, and a water inlet pipe is provided on one of the partition cavities of the partition cavity.

[0014] A refrigeration method for a refrigeration device that recycles condensate includes the following specific steps:

[0015] Step 1: First, the compressor, as the power source of the refrigeration cycle, compresses the low-temperature, low-pressure gaseous refrigerant after it has absorbed heat at the refrigeration end, turning it into a high-temperature, high-pressure gaseous state. Then, this high-temperature, high-pressure gaseous refrigerant is sent into the condenser.

[0016] Step 2: After the refrigerant enters the condenser, condensate is added to the condenser through the water inlet pipe. The condensate then exchanges heat with the refrigerant through the circulation pipe, allowing the refrigerant to continuously release heat and gradually condense from a gaseous state to a high-pressure liquid state. As the condensate heats up, it flows into one of the condenser tubes. The fan is started to drive the airflow to blow the condensate in the condenser tubes to cool it down. Then the high-temperature airflow is discharged from the vent.

[0017] Step 3: After initial cooling, the condensate enters the contraction section. Simultaneously, the hydraulic cylinder is activated, and its piston rod drives the cylinder and shaft to move along the shaft, which in turn drives the first connecting rod to move downward. Subsequently, it drives the rotating column and blades connected to the second connecting rod to rotate on the support cylinder. The condensate begins to rotate through the inclined blades, and the condensate will drive the blades to rotate. Then, it drives the rotating shaft at the bottom of the support cylinder to rotate through the segmented spiral blades supported by the support rod. The water flow will then enter the throat pipe along the contraction section. Subsequently, the water flow enters the diffusion section under the drive of the segmented spiral blades, where the condensate will be dispersed. The condensate will then flow back into the condensate tank through the arrangement pipe for reuse.

[0018] Step 4: The condensed high-pressure liquid refrigerant will enter the receiver for temporary storage, and then flow through the dryer filter to remove moisture and impurities. It will then return to the evaporator to absorb heat again, continuously removing heat and achieving refrigeration.

[0019] The beneficial effects of the present invention are as follows: (1) By designing a cooling component, a regulating component, a decomposition component and a speed-increasing component, the present invention can rapidly cool the condensate while reducing its acidity in a limited space when used in a refrigeration equipment that recycles condensate, thus avoiding corrosion of pipes during long-term use. In addition, the condensate generates centrifugal force during the cooling process, which reduces bacteria in the condensate and also reduces its acidity, thereby improving the working performance of the refrigeration equipment; (2) The present invention uses a regulating component to make the condensate rotate during the circulating cooling and transmission process, and can control the direction of rotation to avoid excessive scaling in the same direction for a long time. At the same time, it can be used as a driving force during the rotation process; (3) The present invention uses a decomposition component and a speed-increasing component to make the condensate have rotational power during the circulation process, which filters the bacterial layer and then decomposes the condensate into carbon dioxide, reducing the acidity of the condensate. At the same time, it can change the rotation direction of the condensate, which ensures the decomposition power and avoids scaling. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] like Figures 1-8 As shown, a refrigeration device for recycling condensate in this embodiment includes a condenser tank 11 and a circulation chamber 12 disposed at one end thereon. A partition chamber 15 is disposed between the condenser tank 11 and the circulation chamber 12. A circulation processing mechanism is disposed inside the circulation chamber 12. The circulation processing mechanism includes an adjustment component 3 and a decomposition component 4, which are used to control the swirling direction of the circulating condensate and to decompose and adsorb the condensate. An acceleration component 5 is disposed on the decomposition component 4. Under the control of the adjustment component 3, the acceleration component 5 achieves descaling of the pipes. A compressor 16, a liquid receiver 17, a dryer filter 18, and an evaporator 19 are disposed at the front end of the condenser tank 11 and are interconnected.

[0031] like Figures 5-6 As shown, the decomposition component 4 includes a constriction section 41, a throat 42 and a diffusion section 43 spliced ​​together and disposed in the circulation cavity 12. Both the constriction section 41 and the diffusion section 43 are T-shaped, and the diffusion section 43 is longer than the constriction section 41.

[0032] like Figures 2-4 As shown, a cooling component 2 for reducing the temperature of condensate is provided on the circulation chamber 12. The cooling component 2 includes transversely evenly arranged tubes 23 disposed on the contraction section 41 and the diffusion section 43. A fan 21 and a vent 22 are respectively disposed before and after the circulation chamber 12. The other end of the tubes 23 is connected to a circulation pipe 13 separated by a partition chamber 15. A water inlet pipe 14 is disposed on one of the partitions of the partition chamber 15. The water inlet pipe 14 can not only add condensate at the beginning of use, but also replenish it during the process of condensate consumption.

[0033] In operation, after the refrigerant enters the condenser tank 11, condensate is added to the condenser tank 11 via the water inlet pipe 14. The condensate then exchanges heat with the refrigerant through the circulation pipe 13, allowing the refrigerant to continuously release heat and gradually condense from a gaseous state to a high-pressure liquid state. As the condensate heats up, it flows into one of the arrangement tubes 23. The fan 21 is activated to drive airflow, blowing away the condensate in the arrangement tube 23 to cool it down. The high-temperature airflow is then discharged from the vent 22. The arrangement tubes 23 are evenly distributed to facilitate rapid cooling by the fan 21, and the multi-tube circulation arrangement ensures sufficient residence time, thereby achieving a lower temperature.

[0034] like Figures 6-8 As shown, the adjusting assembly 3 includes a hydraulic cylinder 31 and a cylinder in a cylinder and shaft 34 that rotates at the piston rod end. The hydraulic cylinder 31 is fixed to the top of the circulation chamber 12. A bracket 33 is provided in the contraction section 41, and a support cylinder 32 rotates on the bracket 33. A rotating column 37 arranged in a ring is provided on the support cylinder 32. A first connecting rod 35 tilted downwards rotates on the cylinder wall in the cylinder and shaft 34, and a second connecting rod 36 fixed to one end of the rotating column 37 rotates at the other end of the first connecting rod 35. A blade 38 is provided at the other end of the second connecting rod 36.

[0035] After initial cooling, the condensate enters the contraction section 41. Simultaneously, the hydraulic cylinder 31 is activated, and its piston rod drives the cylinder in the cylinder and shaft 34 to move along the shaft, thereby driving the first connecting rod 35 to move downward. Subsequently, it drives the rotating column 37 and blade 38 connected to the second connecting rod 36 to rotate on the support cylinder 32. The condensate begins to rotate after passing through the inclined blade 38, and the condensate will drive the blade 38 to rotate. The condensate has a moving force when it flows in, which enables the inclined blade 38 to rotate. During the rotation, the cylinder in the cylinder and shaft 34 is rotatably connected to the piston rod of the hydraulic cylinder 31, and the piston rod is hollow. The cylinder in the cylinder and shaft 34 is sleeved on the outside of the shaft, and the shaft plays a supporting and guiding role.

[0036] The pipe, consisting of a contraction section 41, a throat 42, and a diffuser section 43, utilizes the Venturi principle as the condensate flows. The flow velocity of the condensate increases sharply as it passes through the Venturi tube. Due to the rapid narrowing of the throat 42, a negative pressure is created, generating numerous tiny cavitation bubbles. When these bubbles burst, they release localized high temperature and pressure, which decomposes carbon dioxide in the water, reducing carbon dioxide formation and lowering acidity at the source. It also destroys bacterial cell walls. Simultaneously, the impact force of the bursting bubbles cleans the inner wall of the pipe, reducing biofilm adhesion and indirectly improving subsequent filtration and acidification effects. Furthermore, resin and filter layers can be installed on the inner walls of the contraction section 41, throat 42, and diffuser section 43. After centrifugation of the condensate, impurities are adsorbed and filtered onto the inner walls.

[0037] like Figure 7As shown, the speed-increasing component 5 includes a rotating shaft 51 fixed to the bottom of the support cylinder 32, and a group of support rods 52 are fixed on the rotating shaft 51. A segmented spiral blade 53, conforming to the throat 42, is fixed to the other end of each support rod 52. The rotating shaft 51 at the bottom of the support cylinder 32 then rotates through the segmented spiral blades 53 supported by the support rods 52, causing water to flow along the contraction section 41 into the throat 42. Subsequently, the water flows into the diffusion section 43 under the drive of the segmented spiral blades 53. During the rotation, the condensate's power increases, ensuring that the condensate is decomposed into carbon dioxide, reducing its acidity. The decomposed carbon dioxide is in a free state and can be periodically discharged. The condensate then flows back into the condensate tank 11 through the arrangement pipe 23, achieving recycling. Additionally, the hydraulic cylinder 31 is activated to contract, changing the direction of the blades 38. At this time, the force of the condensate changes the rotation direction of the segmented spiral blades 53, descaling the inner wall and achieving condensate recycling while preventing scale buildup in the pipes.

[0038] A refrigeration method for a refrigeration device that recycles condensate includes the following specific steps:

[0039] Step 1: First, the compressor 16, as the power source of the refrigeration cycle, compresses the low-temperature, low-pressure gaseous refrigerant after the refrigeration end has absorbed heat, turning it into a high-temperature, high-pressure gaseous state. Then, this high-temperature, high-pressure gaseous refrigerant is sent into the condenser tank 11.

[0040] Step 2: After the refrigerant enters the condenser tank 11, condensate is added to the condenser tank 11 through the water inlet pipe 14. Then, the condensate exchanges heat with the refrigerant through the circulation pipe 13, allowing the refrigerant to continuously release heat and gradually condense from a gaseous state to a high-pressure liquid state. As the condensate heats up, it flows into one of the arrangement tubes 23. The fan 21 is started to drive the airflow to blow the condensate in the arrangement tube 23 to cool it down. Then, the high-temperature airflow is discharged from the vent 22.

[0041] Step 3: After initial cooling, the condensate enters the contraction section 41. At the same time, the hydraulic cylinder 31 is activated, and its piston rod drives the cylinder in the cylinder and shaft 34 to move along the shaft, thereby driving the first connecting rod 35 to move down. Subsequently, it drives the rotating column 37 and blades 38 connected to the second connecting rod 36 to rotate on the support cylinder 32. The condensate begins to rotate after passing through the inclined blades 38, and the condensate will drive the blades 38 to rotate. Subsequently, it drives the rotating shaft 51 at the bottom of the support cylinder 32 to rotate through the segmented spiral blades 53 supported by the support rod 52. Then, the water flow will enter the throat pipe 42 along the contraction section 41. Subsequently, the water flow enters the diffusion section 43 under the drive of the segmented spiral blades 53. The condensate will be dispersed and will flow back into the condensate tank 11 through the arrangement pipe 23 for reuse.

[0042] Step 4: The condensed high-pressure liquid refrigerant will enter the receiver 17 for temporary storage, and then flow through the dryer filter 18 to filter out the moisture and impurities. It will then return to the evaporator 19 to absorb heat again and continuously remove heat to achieve refrigeration.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
