Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of refrigeration control technology, and in particular to a refrigeration device, a condensed water treatment structure and a refrigeration method. Background Art
[0002] The popularity of air conditioners has brought convenience to getting through hot weather. Most of the current air conditioners have a rapid cooling mode. In this mode, the air circulation speed and circulation volume in the air conditioner are improved, so more cold air can be quickly blown to every corner of the room, speeding up the drop in indoor temperature.
[0003] In the prior art, the way to achieve rapid cooling is to increase the operating frequency of the compressor. The compressor is the core component of the air conditioning refrigeration system, responsible for compressing the refrigerant into high-temperature and high-pressure gas. By increasing the frequency of the compressor, the circulation speed of the refrigerant in the system can be accelerated.
[0004] However, the high-frequency operation of the compressor consumes a lot of energy, which is not conducive to energy conservation and emission reduction. During cooling, the heat exchanger inside the air conditioner will quickly cool down to below 16°C. At this time, the temperature of the heat exchanger fins will also decrease, and the water vapor in the air will easily condense into water droplets on the surface of the fins. When there are too many water droplets, the fin spacing will be blocked, which will greatly increase the resistance to air flow, resulting in a decrease in ventilation volume, which will in turn reduce the heat exchange efficiency and affect the cooling effect. Therefore, improving the condensation of water droplets between the heat exchanger fins can also improve the cooling efficiency.
[0005] In the current air conditioning structure, there is no device for removing condensed water well. Summary of the invention
[0006] The present invention provides a refrigeration device, a condensed water treatment structure and a refrigeration method to solve the problem in the above-mentioned technology that high-frequency operation of the compressor consumes energy, and the increase of the compressor frequency causes noise problems and shortens the life of the air conditioner.

[0037] The present disclosure provides a refrigeration device, a condensed water treatment structure and a refrigeration method. The water absorption structure of the refrigeration device is used to absorb water within a first preset temperature range and precipitate water within a second preset temperature range. The water absorption structure includes a water absorption area and a drainage area. Each temperature value in the first preset temperature range is lower than each temperature value in the second preset temperature range, so that the water absorption area absorbs the condensed water on the heat exchanger fins within a relatively low temperature range. After that, the heater heats the drainage area again so that the water absorbed by the water absorption area is discharged from the drainage area, so that the continuously condensed condensed water is absorbed by the water absorption area of the water absorption structure and then discharged through the drainage area, and the condensed water on the heater fins is absorbed and removed in a cycle. In addition, the distance between the water absorption area and the fin of the heat exchanger meets the water absorption distance range of the water absorption structure, and the distance between the drainage area and the fin of the heat exchanger exceeds the water absorption distance range. This limitation allows the water absorption process and the drainage process to be performed independently without interfering with each other, ensuring that the water absorption and drainage processes of the water absorption structure are performed in a cycle.
[0038] The present disclosure has at least the following beneficial effects:
[0039] 1. Low refrigeration power consumption: The condensed water on the heat exchanger fins is absorbed by the water absorption structure to keep the fin surface dry, reduce the air flow space occupied by the condensed water, thereby reducing the flow resistance and air side pressure drop, making the air smoother when passing through the fins, increasing the ventilation volume of the heat exchanger, and improving the heat exchange rate. After the heat exchange rate of the heat exchanger is improved, the temperature difference between the refrigerant and the air (or water) can be reduced more quickly, achieving faster heat absorption or heat release, reducing the circulation time of the refrigerant in the system, and ultimately improving the efficiency of the entire refrigeration system, achieving a rapid refrigeration effect. In actual operation, the power used to heat the water absorption structure is usually less than the power used to increase the compressor frequency. The refrigeration device disclosed in the present invention does not need to increase the compressor frequency to achieve rapid refrigeration during refrigeration. It only needs to heat the water absorption structure to improve the efficiency of the entire refrigeration system and achieve a rapid refrigeration effect. Therefore, the power consumption required during the refrigeration process is lower, which is more energy-saving and environmentally friendly.
[0040] 2. Low noise during the refrigeration process: In the prior art, the noise of the compressor operation is usually generated by the high-speed rotation and vibration of the internal components, which manifests as metal impact or vibration sounds. As the frequency increases, the gas flow speed increases, and the noise will increase accordingly. The impact of high-frequency noise on the human body cannot be ignored. Long-term exposure to high-frequency noise can lead to hearing loss. At the same time, high-frequency noise also has a certain impact on the nervous system and psychological system, and can easily lead to symptoms such as insomnia and anxiety. Since the refrigeration process of the present invention does not require increasing the frequency of the compressor, accordingly, it will not generate too much noise, avoiding users from being exposed to high-decibel noise environments for a long time, helping to create a quiet environment, thereby improving the user's sleep quality, allowing users to better rest and restore energy, and improving mental health. It is especially suitable for people with poor sleep quality, people with neurasthenia or noise sensitivity, the elderly and children.
[0041] 3. Longer service life: Compared with existing refrigeration devices, at the same compressor operating frequency, the refrigeration device of the present invention can achieve the refrigeration target more quickly because the ventilation volume of the heat exchanger is increased. After reaching the refrigeration target, the operating frequency of the compressor can be further lowered to maintain the temperature range in the target area. Since the present invention does not need to increase the frequency of the compressor during rapid refrigeration, and can even further reduce the operating frequency of the compressor, the compressor can operate at a lower frequency, reducing the collision or wear of the internal components of the refrigeration device when the compressor rotates at high speed and causes vibration, making the compressor have a longer service life, thereby extending the service life of the refrigeration device.
[0042] 4. High drainage efficiency: In one embodiment, a plurality of through holes are provided in the water absorption area of the water absorption structure, and the width of the through holes is greater than the width of each fin abutting against the water absorption area. When there is a lot of condensed water and the water absorption amount of the water absorption area is saturated, part of the condensed water that is not absorbed by the water absorption structure can slide along the fins under the action of gravity and fall into the through holes, thereby reducing the accumulation of condensed water on the surface of the water absorption area and improving the discharge speed and stability of the condensed water.
[0043] 5. High water absorption efficiency: By setting two water absorption structures, the two water absorption structures are respectively set on the opposite sides of the fins. During cooling, the two water absorption structures absorb water at the same time, which further improves the absorption efficiency and absorption amount of condensed water, making the space for air circulation between the two adjacent fins larger, the air passes through the fins more smoothly, and the cooling efficiency is more stable.

[0056] Embodiment 1
[0057] In this embodiment, Figure 1-3 As shown, a refrigeration device is provided, including: a heat exchanger 100, a condensed water processing structure:
[0058] The heat exchanger 100 has fins 110;
[0059] The condensed water treatment structure includes a water absorption structure 200 and a heater 300;
[0060] The water absorption structure 200 is used to absorb water within a first preset temperature range and precipitate water within a second preset temperature range. The water absorption structure 200 includes a water absorption area 210 and a drainage area 220. Each temperature value in the first preset temperature range is less than each temperature value in the second preset temperature range.
[0061] The water absorption area 210 is configured as:
[0062] The distance between the water absorption area 210 and the fin 110 of the heat exchanger 100 meets the water absorption distance range of the water absorption structure 200, and the distance between the drainage area 220 and the fin 110 of the heat exchanger 100 exceeds the water absorption distance range;
[0063] The heater 300 is used to heat the drainage area 220 .
[0064] In this embodiment, the refrigeration device can be a device with refrigeration function such as an air conditioner or a refrigerator. The heat exchanger 100 is usually called a condenser or an evaporator, which is mainly used for heat exchange to adjust the temperature in the target area. For example, when the air conditioner is running in the cooling mode, the heat exchanger 100 is usually located in the outdoor unit and discharges the heat absorbed from the indoor to the outdoor. Specifically, the refrigerant (such as Freon) becomes a high-temperature and high-pressure gas under the action of the compressor, and then flows through the heat exchanger 100, dissipating the heat into the air by a fan or natural convection, so that the refrigerant becomes a high-pressure liquid at room temperature. The heat exchanger 100 is usually composed of many metal sheets (fins 110) and copper tubes or aluminum tubes. The fins 110 increase the heat exchange area, making the heat exchange more efficient.
[0065] During cooling, the heat exchanger 100 will quickly cool down to below 16°C, and the temperature of the fins 110 will also drop to below the temperature of the surrounding air. When the water vapor content in the air is high enough (i.e., the relative humidity is high), the water vapor will condense into water droplets on the surface of the fins 110. Since the distance between the fins 110 is usually less than 2 mm, and the hydrophilicity of the fins 110 is poor, when the height of the condensed water droplets exceeds half of the distance between the fins 110, the water droplets between the two fins 110 will connect to form a water bridge. The denser the distance between the fins 110, the more serious the "water bridge" phenomenon, which will cause the distance between the fins 110 to be blocked, greatly increase the resistance to air flow, reduce the air flow, reduce the ventilation volume, and thus reduce the heat exchange performance of the entire heat exchanger 100. Due to the reduced heat exchange efficiency, the heat exchanger 100 cannot effectively transfer heat from the refrigerant to the surrounding environment, resulting in the inability to fully reduce the evaporation temperature of the refrigerant, thereby weakening the refrigeration capacity, resulting in poor refrigeration effect of the refrigeration device and failure to meet the expected cooling needs.
[0066] According to measurement, the air volume is 700m³ / h when there is no condensed water on the heat exchanger 100, and the air volume is 600m³ / h when there is condensed water. The air volume will decrease by 15% when there is condensed water. Therefore, improving the condensed water problem between the fins 110 of the heat exchanger 100 can improve the cooling efficiency of the refrigeration device.
[0067] The condensed water treatment structure includes a water absorption structure 200 and a heater 300. The water absorption structure 200 is used to absorb water within a first preset temperature range and precipitate water within a second preset temperature range. The water absorption structure 200 includes a water absorption area 210 and a drainage area 220. Each temperature value in the first preset temperature range is less than each temperature value in the second preset temperature range. During the cooling process, the water absorption area 210 abuts against one side of the fin 110 and absorbs the condensed water on the fin 110 of the heat exchanger 100 within a relatively low temperature range (close to the outdoor temperature). Since the spacing between the fins 110 is relatively close, when the water absorption structure 200 absorbs water, a capillary phenomenon is formed between adjacent fins 110, so that the water absorption structure 200 can better absorb the condensed water from the surface of the fin 110.
[0068] Afterwards, the condensed water flows and diffuses in the water absorption structure 200, and gradually flows to the drainage area 220. At the same time, the heater 300 heats the drainage area 220 again, so that the water absorbed by the water absorption area 210 is discharged from the drainage area 220. After the water in the water absorption area 210 is discharged, it can better absorb the newly generated condensed water, so that the continuously condensed condensed water is absorbed by the water absorption area 210 of the water absorption structure 200, and then discharged through the drainage area 220, so that the condensed water on the fins 110 of the heat exchanger 100 is continuously and repeatedly absorbed.
[0069] In addition, by making the water absorption area 210 contact with the fins 110 of the heat exchanger 100 or the distance between the water absorption area 210 and the fins 110 of the heat exchanger 100 satisfy the water absorption distance range of the water absorption structure 200, and the distance between the drainage area 220 and the fins 110 of the heat exchanger 100 exceeds the water absorption distance range, the water absorption process and the drainage process are carried out independently without interfering with each other, thereby ensuring that the water absorption and drainage processes of the water absorption structure 200 are cyclically carried out.
[0070] In one embodiment, the water absorption distance range includes a case where the distance is 0, that is, the water absorption area 210 is in contact with the fins 110 of the heat exchanger 100, thereby absorbing condensed water more efficiently.
[0071] The water absorption structure 200 can be made of epoxy-functional porous organic polymers (ep-POPs), metal organic framework compounds (MOFs), polymer water absorption structures or silica gel water absorption structures, etc., according to actual needs, and is not limited here. The first preset temperature range and the second preset temperature range are determined according to the material properties of the water absorption structure itself, and are not limited here. For example, if a MOFs structure is selected, the first preset temperature range can be 5°C-25°C, and the second preset temperature range can be 60°C-80°C.
[0072] The proportion of the water absorption area 210 and the drainage area 220 is also set according to actual needs, for example, the water absorption area 210 accounts for 60%, the drainage area 220 accounts for 40%, or the water absorption area 210 accounts for 80%, and the drainage area 220 accounts for 20%. The specific details are not limited here.
[0073] In summary, the present disclosure provides a refrigeration device, which absorbs the condensed water on the fin 110 of the heat exchanger 100 through the water absorption structure 200, so that the surface of the fin 110 remains dry, and the air flow space occupied by the condensed water is reduced, thereby reducing the flow resistance and the air side pressure drop, so that the air passes through the fin 110 more smoothly, increases the ventilation volume of the heat exchanger 100, and improves the heat exchange rate. After the heat exchange rate of the heat exchanger 100 is improved, the temperature difference between the refrigerant and the air (or water) can be reduced more quickly, and heat absorption or heat release can be achieved more quickly, reducing the circulation time of the refrigerant in the system, and finally improving the efficiency of the entire refrigeration system, and achieving a rapid refrigeration effect. In actual operation, the power for heating the water absorption structure 200 is usually less than the power for increasing the compressor frequency. The refrigeration device of the present disclosure does not need to increase the compressor frequency to achieve rapid refrigeration during refrigeration. It only needs to heat the water absorption structure 200 to improve the efficiency of the entire refrigeration system and achieve a rapid refrigeration effect. Therefore, the power consumption required in the refrigeration process is lower, which is more energy-saving and environmentally friendly.
[0074] On the other hand, in the prior art, the noise of compressor operation is usually generated by the high-speed rotation and vibration of internal components, which manifests as metal impact or vibration sounds. As the frequency increases, the gas flow speed increases, and the noise will increase accordingly. The impact of high-frequency noise on the human body cannot be ignored. Long-term exposure to high-frequency noise can lead to hearing loss. At the same time, high-frequency noise also has a certain impact on the nervous system and psychological system, which can easily lead to symptoms such as insomnia and anxiety. Since the refrigeration process of the present invention does not require increasing the frequency of the compressor, accordingly, it will not generate too much noise, avoiding users from being exposed to high-decibel noise environments for a long time, helping to create a quiet environment, thereby improving the user's sleep quality, allowing users to better rest and restore energy, and improving mental health. It is especially suitable for people with poor sleep quality, people with neurasthenia or noise sensitivity, the elderly and children.
[0075] In addition, the refrigeration device of the present invention has a longer service life. Compared with existing refrigeration devices, at the same compressor operating frequency, the refrigeration device of the present invention can achieve the refrigeration target more quickly because the ventilation volume of the heat exchanger 100 is increased. After reaching the refrigeration target, the operating frequency of the compressor can be further lowered to maintain the temperature range in the target area. Since the present invention does not need to increase the frequency of the compressor during rapid refrigeration, and can even further reduce the operating frequency of the compressor, the compressor can operate at a lower frequency, reducing the collision or wear of the internal components of the refrigeration device when the compressor rotates at high speed and causes vibration, making the compressor have a longer service life, thereby extending the service life of the refrigeration device.
[0076] In some embodiments, Figure 4 As shown, the water absorption area 210 of the water absorption structure 200 is provided with a plurality of through holes 211 , the edge of one end of the through hole 211 abuts against the fin 110 of the heat exchanger 100 , and the width of the through hole 211 is greater than the width of each fin 110 abutting against the water absorption area 210 .
[0077] In this embodiment, when the ambient humidity is particularly high, the water absorption area 210 may be in a saturated state, and there is no time to absorb more condensed water. Some of the condensed water that is not absorbed can drip into the through hole 211 under the action of gravity. The width of the through hole 211 is greater than the width of each fin 110 abutting against the water absorption area 210, so that the condensed water can drip more smoothly, reducing the situation where the condensed water gathers on the surface of the water absorption area 210, and improving the discharge speed and stability of the condensed water.
[0078] The width of the through hole 211 can be set according to the actual installation requirements. For example, the width of the fin 110 abutting against the water absorption area 210 (or the thickness of the fin 110) is 0.05 mm, and the width of the through hole 211 is set to 2 mm, so that the condensed water can drip better. In one embodiment, ten fins 110 can also abut against the edge of one end of the same through hole 211, and the spacing between the fins 110 is 1.2 mm, and the width of the corresponding through hole 211 is set to 5 cm. The opening size of the through hole 211 is adapted to the number of abutting fins 110, and is not specifically limited here.
[0079] In some embodiments, the number of the water absorption structures 200 is two, and the two water absorption structures 200 are respectively disposed on two opposite sides of the fin 110 .
[0080] In this embodiment, in order to further improve the absorption efficiency of condensed water, a water absorption structure 200 is respectively provided on two opposite sides of the fin 110. For example, when the fin 110 is rectangular, two water absorption structures 200 can be respectively installed at the upper and lower ends of the fin 110. During cooling, the two water absorption structures 200 absorb water at the same time, further improving the absorption efficiency and absorption amount of condensed water, making the air circulation space between the adjacent two fins 110 larger, the air passes through the fin 110 more smoothly, and the cooling efficiency is more stable.
[0081] In one embodiment, in order to achieve a better water absorption effect, the surfaces of the water absorption area 210 and the fin 110 that abut against each other fit each other. For example, when the side of the fin 110 abutting against the water absorption area 210 is an inclined surface, the corresponding water absorption area 210 is also provided with an inclined surface to match the fin 110; when the side of the fin 110 abutting against the water absorption area 210 is an arc surface, the water absorption area 210 is also provided with an arc surface to match the fin 110.
[0082] In some embodiments, Figure 2 As shown, the refrigeration device also includes:
[0083] The base 400 is connected to the heat exchanger 100 . The base 400 is provided with a condensation water channel 410 . The condensation water channel 410 is used to receive and discharge the water precipitated from the drainage area 220 .
[0084] In this embodiment, the condensed water can be guided to be discharged more timely through the condensed water channel 410, thereby preventing the condensed water from dripping to other places and affecting the use effect of the refrigeration device.
[0085] In one embodiment, the through hole 211 is connected to the condensed water channel 410 , and the condensed water that the water absorption area 210 has not had time to absorb can directly fall into the condensed water channel 410 and be directly drained when it drips from the through hole 211 .
[0086] In some embodiments, Figure 5 As shown, the water absorption area 210 has a water absorption surface, which is in contact with the fins 110 of the heat exchanger 100 . The water absorption structure 200 is provided with a first water guide rib 212 on one side other than the water absorption surface, and the first water guide rib 212 is connected to the drainage area 220 .
[0087] In this embodiment, if Figure 5As shown, a plurality of parallel first grooves are provided on the side of the water absorption area 210 away from the water absorption surface, and first water guide ribs 212 are formed between adjacent first grooves. The arrangement of the grooves and ribs increases the three-dimensional space on the surface of the water absorption structure 200, forming a structure similar to a gully, which can prevent condensed water from randomly spreading on the surface of the water absorption structure 200. After the condensed water is absorbed, the condensed water will gather toward the first water guide ribs 212 under the action of gravity and surface tension, thereby achieving the effect of quickly guiding the condensed water to flow to the drainage area 220.
[0088] In some embodiments, the water absorbing structure 200 is provided with a second water guiding rib 221 in the drainage area 220 , and the second water guiding rib 221 is connected to the first water guiding rib 212 .
[0089] In this embodiment, Figure 5 As shown, a plurality of parallel second grooves are provided on the side of the drainage area 220 away from the water absorption surface, and second water guiding ribs 221 are formed between adjacent second grooves. The second water guiding ribs 221 are connected to the first water guiding ribs 212 , so that condensed water is finally gathered on the second water guiding ribs 221 .
[0090] Since the drain area 220 is provided with a heater 300, when heated, the water on the second water guide ribs 221 is heated and precipitated. Since the second water guide ribs 221 make the surface of the drain area 220 no longer flat, the raised second water guide ribs 221 have a smaller surface area, and the surface tension and water collection capacity are weaker, so that the condensed water is more easily discharged under the action of its own gravity.
[0091] In some embodiments, the second water guiding ribs 221 are staggeredly arranged in the drainage area 220 .
[0092] In this embodiment, the second water guide ribs 221 are distributed in the drainage area 220 in a "well" or grid shape. The second water guide ribs 221 are staggered, so that the surface tension of the drainage area 220 is further weakened, and the condensed water is more easily diffused to the second water guide ribs 221 after being heated, and finally precipitated faster.
[0093] In some embodiments, the heater 300 is disposed in contact with the surface of the drainage area 220 .
[0094] In this embodiment, the heater 300 can be arranged on any surface except the surface where the second water guide rib 221 is located. For example, it can be arranged on a surface of the drainage area 220 away from the second water guide rib 221. By making the heater 300 arranged on the surface of the drainage area 220, the drainage area 220 can be heated more evenly, so that the condensed water can be precipitated faster.
[0095] Embodiment 2
[0096] The present disclosure provides a condensate treatment structure, such as Figure 3-Figure 5 As shown, it includes a water absorption structure 200 and a heater 300,
[0097] The water absorption structure 200 is used to absorb water within a first preset temperature range and precipitate water within a second preset temperature range. The water absorption structure 200 includes a water absorption area 210 and a drainage area 220. Each temperature value in the first preset temperature range is less than each temperature value in the second preset temperature range.
[0098] The water absorption area 210 is configured as:
[0099] The distance between the water absorption area 210 and the target object to be absorbed meets the water absorption distance range of the water absorption structure 200, and the distance between the drainage area 220 and the target object to be absorbed exceeds the water absorption distance range;
[0100] The heater 300 is used to heat the drainage area 220 .
[0101] The condensate treatment structure and use in the present disclosure are similar to those in the above-mentioned embodiment, and are not described here in detail to avoid repetition. The condensate treatment structure of the present disclosure can be used to absorb water from a structure having heat dissipation fins 110, such as a heat exchanger 100 in an air conditioner, or a heat exchanger 100 in an air-cooled heat pump unit, to improve the efficiency and energy-saving performance of the equipment.
[0102] In some embodiments, the water absorbing structure 200 is provided with a plurality of through holes 211 .
[0103] When the ambient humidity is particularly high, the water absorption area 210 may be in a saturated state, and there is no time to absorb more condensed water. Some of the condensed water that is not absorbed can drip into the through hole 211 under the action of gravity. When the condensed water treatment structure of the present disclosure is applied to the air conditioner radiator, the width of the through hole 211 is greater than the width of each fin 110 abutting against the water absorption area 210, so that the condensed water can drip more smoothly, reducing the situation where the condensed water accumulates on the surface of the water absorption area 210, and improving the discharge speed and stability of the condensed water.
[0104] In some embodiments, the water absorption area 210 has a water absorption surface, and the water absorption structure 200 is provided with a first water guide rib 212 on one side other than the water absorption surface, and the first water guide rib 212 is connected to the drainage area 220 .
[0105] In the present disclosure, a plurality of parallel first grooves can be provided on the side of the water absorption area 210 away from the water absorption surface, and a first water guide rib 212 is formed between adjacent first grooves. The arrangement of the grooves and ribs increases the three-dimensional space on the surface of the water absorption structure 200, forming a structure similar to a gully, which can prevent condensed water from randomly spreading on the surface of the water absorption structure 200. After the condensed water is absorbed, the condensed water will gather toward the first water guide rib 212 under the action of gravity and surface tension, thereby achieving the effect of quickly guiding the condensed water to flow to the drainage area 220.
[0106] In some embodiments, the water absorbing structure 200 is provided with a second water guiding rib 221 in the drainage area 220 , and the second water guiding rib 221 is connected to the first water guiding rib 212 .
[0107] In the present disclosure, a plurality of parallel second grooves may be provided on the side of the drainage area 220 away from the water absorption surface, and second water guide ribs 221 are formed between adjacent second grooves. The second water guide ribs 221 are connected to the first water guide ribs 212 , so that condensed water is finally gathered on the second water guide ribs 221 .
[0108] Since the drain area 220 is provided with a heater 300, when heated, the water on the second water guide ribs 221 is heated and precipitated. Since the second water guide ribs 221 make the surface of the drain area 220 no longer flat, the raised second water guide ribs 221 have a smaller surface area, and the surface tension and water collection capacity are weaker, so that the condensed water is more easily discharged under the action of its own gravity.
[0109] In some embodiments, the water absorbing structure 200 is made of a metal organic framework compound.
[0110] In the present disclosure, metal organic framework compounds (MOFs) are selected as the material of the water absorption structure 200. MOFs have a large specific surface area and a highly ordered pore structure, so that a large amount of water molecules can be absorbed. MOFs can still maintain a good structure after multiple cycles of water absorption and drainage, and has high stability.
[0111] Embodiment 3
[0112] In this disclosure, Figure 6 As shown, a refrigeration method is provided, which is applied to any of the above refrigeration devices, comprising:
[0113] Step 1, receiving a cooling instruction;
[0114] Step 2, such as Figure 2 and Figure 3As shown, in response to the cooling instruction and according to preset parameters for cooling, the heater 300 is turned on, wherein the heater 300 is used to heat the water absorption structure 200 arranged on one side of the fin 110 of the heat exchanger 100, and the preset parameters include at least one of a preset internal fan speed and a preset compressor speed.
[0115] The refrigeration method disclosed in the present invention, after receiving the refrigeration instruction, performs refrigeration according to the preset compressor speed, and then controls the heater 300 to turn on to heat the drainage area 220 of the water absorption structure 200. During the entire refrigeration process, the heater 300 remains in a normally open state to continuously absorb and discharge the condensed water on the fins 110, and keep the ventilation volume between the fins 110 stable.
[0116] In some embodiments, the water absorption and drainage efficiency of the water absorption structure 200 can also be controlled by adjusting the temperature of the heater 300. For example, by detecting the humidity level of the water absorption structure 200, when the humidity level reaches a first preset value, the heater 300 is controlled to heat the water absorption area 210 at a first temperature. When the humidity level reaches a second preset value, the heater 300 is controlled to heat the water absorption area 210 at a second temperature, and the heating temperature is directly proportional to the humidity value.
[0117] When the heating temperature is different, the drainage effect of the drainage area 220 is different. Generally, the higher the temperature within the drainage temperature range, the better the drainage effect. When the humidity level is low, the water absorption structure 200 is slightly heated. When the humidity level is high, the drainage area 220 is heated at a high temperature to increase the drainage speed. By controlling the temperature of the heater 300, the drainage efficiency can be controlled more accurately, avoiding energy waste.
[0118] In some embodiments, responding to the cooling instruction and performing cooling according to preset parameters and turning on the heater 300 includes:
[0119] In response to the cooling instruction and according to the preset parameters, cooling is performed and the heater 300 is turned on after a preset time when cooling starts.
[0120] In this embodiment, turning on the heater 300 after the preset time can be to turn on the heating 5 seconds after receiving the rapid cooling instruction, so as to achieve the rapid cooling effect. When the cooling instruction is the conventional cooling mode, the heater 300 can be turned on after 1 minute, or the heater 300 can be turned off. The specific time setting depends on the demand, and the coefficient is not limited.
[0121] In some embodiments, the refrigeration method further comprises:
[0122] Detect whether the temperature in the target area reaches the preset temperature;
[0123] When the temperature in the target area reaches the preset temperature, the internal fan speed and / or the preset compressor speed are reduced.
[0124] In this embodiment, compared with the existing refrigeration device, at the same compressor operating frequency, the refrigeration device of the present disclosure can achieve the refrigeration target more quickly due to the increased ventilation volume of the heat exchanger 100. After the refrigeration target is achieved, for comfort and health considerations, the operating frequency of the compressor can be further reduced, and / or the internal fan frequency can be reduced to maintain the temperature range in the target area, while further reducing noise and energy consumption.
[0125] Embodiment 4
[0126] Based on the above embodiments, Figure 1-Figure 5 As shown, this embodiment provides an application example.
[0127] This embodiment is applied to a wall-mounted unit. By installing a water absorption structure 200 inside the wall-mounted unit, all the water condensed on the heat exchanger 100 due to condensation is quickly absorbed by utilizing the principle of rapid water absorption when encountering cold and rapid water precipitation when encountering heat, thereby reducing the wind resistance passing through the condenser, increasing the air intake volume, and improving the heat exchange efficiency of the heat exchanger 100. The air conditioner can achieve a rapid cooling effect without increasing the compressor frequency, thereby reducing the power consumption of the air conditioner and increasing the life of the product.
[0128] Specifically, the water absorption structure is a MOFs water absorption structure 200, which absorbs water quickly in the range of 5°C-25°C, and quickly precipitates water and drains water in the range of 6°C-80°C. The water absorption structure 200 is installed between the bottom shell and the heat exchanger 100, and a condensation water channel 410 is opened on the bottom shell, and the water absorption structure 200 is arranged above the condensation water channel 410.
[0129] The water absorption structure 200 is arranged in a rectangular parallelepiped, and the drainage area 220 is arranged at one end of the water absorption structure 200. A heater 300 is mounted in the drainage area 220. The top of the water absorption structure 200 is a plane structure that is in full contact with the fins 110 of the heat exchanger 100. The plane is designed with holes at intervals, and the lower part in contact with the heat exchanger 100 is designed with a horizontal first water guide rib 212, which is conducive to the water transporting condensed water to the drainage area 220; the drainage area 220 is designed with a criss-cross second water guide rib 221 at the position where it cooperates with the heater 300, which is convenient for rapid precipitation of water.
[0130] When the air conditioner is in cooling mode, the heat exchanger 100 will quickly cool down to below 16°C, and condensed water will form between the fins 110, blocking the air inlet path, affecting the air volume, and reducing the heat exchange efficiency. At the same time, in order to ensure the cooling efficiency, the speed of the indoor unit is increased to increase the air intake volume or the operating frequency of the compressor is increased to reduce the temperature of the heat exchanger 100. Increasing the speed of the indoor unit will increase the noise of the indoor unit, and increasing the frequency of the compressor will increase the noise of the outdoor unit, and it will affect the service life of the product.
[0131] The present invention designs a water absorption structure 200 (MOFs) structure between the bottom shell and the heat exchanger 100. When the cooling mode is turned on, the temperature inside the heat exchanger 100 and the air conditioner quickly drops to below 16°C. At this time, a lot of condensed water condenses on the heat exchanger 100. At the same time, the water absorption structure 200 reaches the temperature point of rapid water absorption. The condensed water on the heat exchanger 100 is all absorbed by the water absorption structure 200 through capillary phenomenon. At this time, there is no condensed water on the heat exchanger 100, and the air intake will not decrease. At the same time, the heater 300 starts to operate, so that the temperature of the drainage area 220 reaches 60°C or above to quickly precipitate water, and then the water on the water absorption structure 200 below the heat exchanger 100 is transported to the leftmost side to heat up and precipitate water, and then drained away. In this way, the water on the heat exchanger 100 is quickly drained by reciprocating operation, thereby ensuring the air intake and achieving the effect of rapid cooling.
[0132] When the ambient humidity is particularly high, the water absorption structure 200 does not have time to absorb the condensed water of the heat exchanger 100, and the condensed water on the heat exchanger 100 flows directly to the water channel of the base 400 through the holes on the surface of the water absorption structure 200 that contacts the heat exchanger 100 and is discharged.
[0133] When the present invention realizes rapid cooling and the room temperature reaches the set comfortable temperature, if it continues to run, the room temperature will become lower and lower, and the user will feel cold. In order to ensure that the room temperature is not too low, the present invention keeps the indoor unit air volume unchanged, and the indoor unit speed can be reduced to reduce the air volume (at the same time, the indoor unit noise is also reduced, improving the user experience), and the cooling capacity can be reduced to keep the room temperature at the most comfortable temperature; or the indoor unit speed is not changed, and the frequency of the outdoor unit compressor or the speed of the outdoor fan is reduced to reduce the cooling capacity and reduce energy consumption.
