With reference to fig. 1, an embodiment of the present disclosure provides a method for detecting a water-repellent capacity of a heat exchanger fin, including:
s21, spraying water to the heat exchanger and standing the heat exchanger;
s22, determining the residual situation of the water after the heat exchanger is placed still;
and S23, determining the water-repellent capacity of the heat exchanger fin according to the residual situation of the water after the heat exchanger is stood still.
The water-repellent capacity of the heat exchanger fins is very important during the operation of the air conditioner. The hydrophobic ability represents the water repelling ability of the fin, the stronger the hydrophobic ability of the fin, the harder the water stays on the surface of the fin, and the weaker the hydrophobic ability, the easier the water adheres to the surface of the fin. When the heat exchanger is used as an evaporator, the temperature of the fins is low, and the temperature of air around the evaporator is higher than that of the fins, so that moisture in the air is easy to condense on the surfaces of the fins to form condensed water. After the condensed water is produced, if the hydrophobic capacity of the fin surface is strong, the condensed water can flow downwards along the fin surface rapidly and is separated from the heat exchanger, and the heat exchange effect of the heat exchanger is not affected basically. If the hydrophobic capacity of the fins is weak, the condensed water will adhere to the surfaces of the fins for a longer time and even more water will accumulate. More moisture is easily remained on the surface of the fin under the condition of unsmooth water flow, so that the blockage of a wind path of the heat exchanger can be caused, and the heat exchange effect of the fin and the external environment is influenced.
The hydrophobic capacity of the heat exchanger fin can be derived from a hydrophobic material used for the heat exchanger fin, and a hydrophobic coating can also be coated on the surface of the fin. The method has the advantages that the hydrophobic capacity of the heat exchanger fin is detected, the strength of the hydrophobic capacity of the heat exchanger fin can be judged, and whether the hydrophobic capacity of the heat exchanger fin meets application requirements or not can be judged.
And determining the residual condition of the water after the heat exchanger is kept still, and judging the hydrophobic capacity of the heat exchanger fin. After water is sprayed to the heat exchanger, part of water flows downwards along the heat exchanger fins and is separated from the heat exchanger, and part of water is remained on the heat exchanger fins. Some moisture may remain on the surfaces of the heat exchanger after the heat exchanger is allowed to stand. The residual condition of the moisture after the heat exchanger is stood reflects the water-repellent capacity of the heat exchanger fin, so that the residual condition can be used for determining the water-repellent capacity of the heat exchanger fin. Optionally, the residual situation of the moisture after the heat exchanger is left standing is the residual quantity of the moisture after the heat exchanger is left standing. The residual amount of moisture can be calculated. Optionally, Δ M is M3-M1, where Δ M is the residual amount of moisture after the heat exchanger is left standing, M3 is the weight after the heat exchanger is left standing, and M1 is the original weight of the heat exchanger. The residual condition of the water after the heat exchanger stands can be determined by calculating the weight difference value of the heat exchanger.
Optionally, the heat exchanger is weighed by a weighing device. The heat exchanger may be placed on a weighing device for weighing. The weight of the heat exchanger after standing was recorded to determine the hydrophobic capacity of the heat exchanger fins. Optionally, the heat exchanger is sprayed with water by a water spraying device. Optionally, the water spraying device comprises: one or more of a first spray head, a second spray head and a third spray head, wherein the first spray head faces the top of the heat exchanger, the second spray head faces the side of the heat exchanger, and the third spray head faces the bottom of the heat exchanger. The first spray head can spray water to the heat exchanger from the top of the heat exchanger, the second spray head can spray water to the heat exchanger from the side of the heat exchanger, and the third spray head can spray water to the heat exchanger from the bottom of the heat exchanger. One of the three spray heads in different directions can be selected to be arranged, and various spray heads can be mixed to be arranged, so that the heat exchanger can be conveniently and rapidly wetted comprehensively.
In a practical application scenario, the method can be used for detecting the water-repellent capacity of the heat exchanger fin after the heat exchanger is manufactured. A heat exchanger qualified in water-repellent capacity can be installed in an air conditioning apparatus. The heat exchanger can be applied to an air conditioner, a refrigerator or a dehumidifier.
The heat exchanger can be clamped by arranging the clamping device, so that the heat exchanger can be fixed, and the water spraying to the heat exchanger is facilitated. The clamping device can adjust the clamping angle, so that the angle of the heat exchanger can be adjusted to the angle in the actual application scene. For example, heat exchangers are typically tilted at an angle in an air conditioning unit, and the heat exchanger can be tilted at the same angle as in the unit by adjusting the clamping angle of the clamping device.
Optionally, the standing time is 0.1min to 1.5 min. Within the time range, the hydrophobic capacity of the heat exchanger fin can be accurately reflected. If the standing time is too long, the water on the surface of the heat exchanger fin is possibly evaporated, so that the hydrophobic capacity judgment is inaccurate. If the standing time is too short, the heat exchanger fin may not be sufficiently hydrophobic, and the judgment of the hydrophobic capacity of the heat exchanger fin is also influenced.
In some embodiments, the residual moisture after the heat exchanger is allowed to stand is a ratio of the residual moisture after the heat exchanger is allowed to stand to the residual moisture immediately after the heat exchanger sprays water. Most of water flows downwards to separate from the heat exchanger immediately after the water is sprayed by the heat exchanger, a small part of water remains on the surface of the heat exchanger, and after the heat exchanger is kept still for a period of time, the water on the surface of the heat exchanger is continuously reduced, and less part of water remains on the surface of the heat exchanger. By determining this ratio, the water-repelling ability of the heat exchanger fin can be known. When the ratio value is large, the water-repellent capacity of the heat exchanger fin is weak, and when the ratio value is small, the water-repellent capacity of the heat exchanger fin is strong.
Referring to fig. 2, in some embodiments, determining the hydrophobic property of the heat exchanger fin according to the residual moisture after the heat exchanger is stood includes:
s231, comparing the ratio of the residual quantity of the water after the heat exchanger is stood to the residual quantity of the water after the heat exchanger just sprays water with a preset value;
s232, determining that the water-repellent capacity of the heat exchanger fin meets the use requirement under the condition that the proportion is smaller than a preset value.
And setting a preset value as a judgment standard, comparing the proportion of the residual quantity of the water after the heat exchanger is stood to the residual quantity of the water after the heat exchanger just sprays water with the preset value, and under the condition that the proportion is smaller than the preset value, indicating that the residual water of the heat exchanger is less, and enabling most of water to be separated from the heat exchanger through the hydrophobic performance of the heat exchanger fins. In this way, the water-repellent capacity of the heat exchanger fin can be determined to meet the use requirement.
Optionally, the proportion of the residual amount of moisture after the heat exchanger is stood to the residual amount of moisture immediately after the heat exchanger sprays water is determined by the following equation:
k＝(M3-M1)/(M2-M1)，
wherein k is the proportion of the residual amount of the water after the heat exchanger is stood to the residual amount of the water after the heat exchanger just sprays water, M3 is the weight of the heat exchanger after being stood, M1 is the original weight of the heat exchanger, and M2 is the weight of the heat exchanger just sprays water. The ratio can be calculated by this equation.
Optionally, k is 0.2. And taking the k value as a standard for judging the hydrophobic capacity, wherein when the k value is smaller than the k value, the hydrophobic capacity of the heat exchanger fin is qualified, and when the k value is larger than or equal to the k value, the hydrophobic capacity of the heat exchanger fin is unqualified.
In some embodiments, the residual condition of the moisture after the heat exchanger is placed still is the residual quantity of the moisture after the heat exchanger is placed still, and the less the residual quantity of the moisture after the heat exchanger is placed still, the stronger the hydrophobic capacity of the heat exchanger fin is.
The residual amount is small, which means that most of the water is difficult to stay on the surface of the fin, but flows down rapidly along the fin and leaves the heat exchanger, so that the residual water on the surface of the heat exchanger is very little, and the residual amount of the heat exchanger is very small. The smaller the residual amount, the less the water retained on the fin surface, and the stronger the hydrophobic ability of the heat exchanger fin. The residual quantity is large, which indicates that moisture is easy to stay on the surface of the fin and is difficult to flow away, thereby causing the residual quantity of the heat exchanger to be large. The larger the residual amount, the more water retained on the fin surface, and the weaker the hydrophobic ability of the heat exchanger fin. And the strength rule of the hydrophobic capacity of the heat exchanger fin can be known according to the rule of the residual quantity.
In some embodiments, before spraying water to the heat exchanger and allowing the heat exchanger to stand, the method further comprises: the water spray pattern is determined according to the use of the heat exchanger.
The heat exchangers have different purposes, different water contents of air in working environments, and different condensation modes on the surfaces of the heat exchanger fins. The water spraying mode is determined according to the application of the heat exchanger, the environment condition of the heat exchanger in actual use is simulated, and the detected water draining capacity has a reference value. And after the water spraying mode is determined, spraying water to the heat exchanger in the water spraying mode, and detecting the water drainage capacity of the heat exchanger fin. The heat exchanger may be used to condition air temperature and may also be used to condition air humidity. When the heat exchanger is applied to an air conditioner or a refrigerator, the heat exchanger is used for refrigeration, and when the heat exchanger is applied to a dehumidifier, the heat exchanger is used for dehumidification. When the heat exchanger operates for refrigeration, the refrigerant circulating in the heat exchanger releases cold energy, the temperature of the fins of the heat exchanger is reduced, and water vapor is condensed on the surfaces of the fins. When the heat exchanger is used for dehumidification, the temperature of the heat exchanger fins is lower than that of the heat exchanger fins during refrigeration, and more condensed water is generated on the surfaces of the heat exchanger fins.
Referring to fig. 3, an exemplary method for detecting the hydrophobic capacity of a heat exchanger fin includes:
s11, determining a water spraying mode according to the use of the heat exchanger;
s21, spraying water to the heat exchanger and standing the heat exchanger;
s22, determining the residual situation of the water after the heat exchanger is placed still;
and S23, determining the water-repellent capacity of the heat exchanger fin according to the residual situation of the water after the heat exchanger is stood still.
Through the embodiment, when the water-repellent capacity of the heat exchanger fin is detected, water is sprayed to the heat exchanger according to the purpose control of the heat exchanger, then the residual situation of water after the heat exchanger is kept still is determined based on the water spraying situation, and further the water-repellent capacity of the heat exchanger fin is determined. Therefore, the detected hydrophobic capacity can reflect the hydrophobic condition of the heat exchanger in the actual application scene more accurately.
Optionally, the use comprises for conditioning air temperature or for conditioning air humidity. The heat exchanger is used for circulating a refrigerant to adjust air, and is generally used for adjusting air temperature or humidity. The heat exchanger has lower temperature, and can exchange heat with air to refrigerate. When the temperature of the heat exchanger is lower, a large amount of surrounding water vapor can be condensed on the heat exchanger, and dehumidification is realized. When the heat exchanger performs refrigeration or dehumidification, the amount of water condensed on the surfaces of the heat exchanger fins is different, and the amount of water condensed in the dehumidification case is higher.
In some embodiments, the determining the water spray pattern, based on the use of the heat exchanger, comprises:
under the condition that the heat exchanger is used for adjusting the air temperature, the water spraying mode is spraying water drops;
under the condition that the heat exchanger is used for adjusting air humidity, the water spraying mode is water mist spraying.
In the case of heat exchangers for conditioning the air temperature, the heat exchangers can be sprayed in a drop-like spray pattern. Under the condition that the heat exchanger is used for adjusting air humidity, the heat exchanger can be sprayed in a water mist mode, and a large amount of condensed water is generated on the surfaces of fins of the heat exchanger. Therefore, the water-repellent capacity of the heat exchanger in the practical application scene can be reflected.
In some embodiments, after determining the water spray mode and before spraying water to the heat exchanger, the method further comprises:
and under the condition that the heat exchanger is used for adjusting the air temperature, the water injection amount of the heat exchanger is adjusted according to the heat exchange capacity of the heat exchanger.
The heat exchange capacity of the heat exchanger is different, the condensation tendency of the water vapor on the surface of the heat exchanger fin is different, the larger the heat exchange capacity of the heat exchanger is, the easier the water vapor is to be condensed on the surface of the heat exchanger fin, namely, the larger the water amount which can be condensed by the heat exchanger fin is. In practical application, when the heat exchanger needs to be applied to an air conditioner, the larger the refrigerating capacity of the air conditioner is, the stronger the heat exchange capacity of the heat exchanger is, and the more easily the water vapor is condensed on the surfaces of the fins of the heat exchanger. On the contrary, the smaller the refrigerating capacity of the air conditioner is, the smaller the heat exchange capacity of the heat exchanger is, and the condensation tendency of the water vapor on the surfaces of the fins is also weakened. Therefore, the water spraying amount of the heat exchanger is adjusted according to the heat exchange capacity of the heat exchanger, and the water drainage capacity of the heat exchanger fin can be accurately detected.
After the heat exchanger is manufactured, the heat exchange capacity of the heat exchanger can be determined according to the refrigerating capacity of the refrigerating equipment to which the heat exchanger is applied. For example, if the refrigerating capacity of the refrigerating equipment is one, the heat exchange capacity of the heat exchanger is set to be one level; and if the refrigerating capacity of the refrigerating equipment is two, setting the heat exchange capacity of the heat exchanger as two stages, and the like. And after the heat exchange capacity of the heat exchanger is determined, adjusting the water spraying amount of the heat exchanger according to the heat exchange capacity of the heat exchanger.
In some embodiments, adjusting the amount of water spray to the heat exchanger is accomplished by adjusting the transport speed of the heat exchanger through the water spray zone.
Adjusting the amount of water spray can be accomplished by adjusting the rate of conveyance of the heat exchanger through the water spray zone. The heat exchanger can be conveyed to the water spraying area through the conveying device to spray water, and the conveying device enables the heat exchanger to pass through the water spraying area to receive spraying at a certain conveying speed. With a fixed time, the faster the transport speed, the less water is sprayed to the heat exchanger, i.e. the heat exchanger receives. Conversely, the slower the transport speed, the more water is sprayed to the heat exchanger. If the heat exchanger is arranged on the clamping device, the clamping device can be arranged on the conveying device, and the clamping device and the heat exchanger are conveyed to the water spraying area together to spray water.
Through this embodiment, adjust the volume of spraying water to the heat exchanger with the mode of adjusting transfer speed, convenient control also is convenient for detect the hydrophobic ability of a plurality of heat exchanger fins.
Illustratively, a numerical comparison table between the heat exchange capacity of the heat exchanger and the conveying speed is preset, and the conveying speed is determined in a table look-up manner. Taking the length of the water spraying area as 1m as an example, the numerical table of the heat exchange capacity, the transmission speed and the air conditioning refrigerating capacity of the heat exchanger is as follows:
| refrigerating capacity of air conditioner | Heat exchange capacity of heat exchanger | Speed of conveyance |
| 1 piece of | First stage | 0.06m/s |
| 2 pieces of | Second stage | 0.05m/s |
| 3 pieces of | Three-stage | 0.04m/s |
| 4 pieces of | Four stages | 0.04m/s |
| 5 pieces of | Five stages | 0.04m/s |
