Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] The operating principle of the water-cooled air conditioner involved in the embodiments of this application is described in detail below: Water-cooled air conditioners, also known as eco-friendly air conditioners, water air conditioners, water curtain air conditioners, evaporative coolers, and chillers, are evaporative cooling and ventilation units developed using modern science and technology. They integrate functions such as cooling, ventilation, humidification, dust prevention, deodorization, and increasing the oxygen content of the air. They do not have compressors or use refrigerants; their core components are motors and evaporative cooling curtains. They can solve environmental problems in living and working environments at a very low cost.

[0033] The working principle of water-cooled air conditioners is as follows: a circulating water pump continuously draws water from the bottom basin of the air conditioner and sprays it evenly onto the evaporative cooling pad through a water distributor, making the entire evaporative cooling pad uniformly wet. The operation of the fan forces the outside air to pass through the evaporative cooling pad, whose actual heat exchange area is many times larger than the surface area. The heat in the air is absorbed and turned into fresh cold air, which is blown out from the air outlet, thereby achieving the cooling effect.

[0034] To address the aforementioned technical problems in related technologies, this application provides a method for preventing scale buildup in a kitchen water-cooled air conditioner. This method calculates a scale condensation temperature threshold based on the pH value and total dissolved solids (TDS) value of the liquid within the pipe. This threshold characterizes the temperature at which scale easily condenses in the pipe. Subsequently, the compressor frequency is adjusted by comparing the temperature of the liquid within the pipe with this scale condensation temperature threshold to prevent excessively high water temperatures from causing excessive scale buildup and precipitation. Finally, the accumulated scale amount can be calculated using the pH value, TDS value, and temperature of the liquid within the pipe to determine whether descaling is necessary.

[0035] The method for preventing scale buildup in kitchen water-cooled air conditioners provided in this application will be described in detail below with reference to the accompanying drawings and specific embodiments and application scenarios.

[0036] like Figure 1 As shown in the embodiment of this application, a method for preventing scale buildup in a kitchen water-cooled air conditioner is provided. This method may include the following steps 101 and 102: Step 101: During the heat exchange process of the water-cooled air conditioner, obtain the target parameters of the water-cooled air conditioner.

[0037] The target parameters include: the pH value of the liquid in the pipeline, the total dissolved solids (TDS) value of the liquid in the pipeline, and the temperature of the liquid in the pipeline.

[0038] For example, during the heat exchange process of a water-cooled air conditioner, the pH value, total dissolved solids (TDS) value, and temperature of the liquid in the pipe are obtained in real time by a TDS sensor, pH sensor, and temperature sensor installed inside the water-cooled air conditioner.

[0039] Step 102: Execute the corresponding anti-scaling control strategy based on the target parameters.

[0040] The ease with which scale forms is positively correlated with the pH value of the liquid in the pipe; the ease with which scale forms is positively correlated with the TDS value of the liquid in the pipe; and the ease with which scale forms is positively correlated with the temperature of the liquid in the pipe.

[0041] For example, after obtaining the pH value, total dissolved solids (TDS) value, and temperature of the liquid in the pipe, the compressor of the water-cooled air conditioner can be controlled to prevent the water temperature in the pipe from being too high, which would lead to excessive scale formation.

[0042] Specifically, step 102 above may also include step 102a: Step 102a: Determine the scale condensation temperature threshold based on the pH value of the liquid in the pipe and / or the TDS value of the liquid in the pipe.

[0043] For example, scale formation is closely related to the acidity, or alkalinity, of water; pH value influences scale formation to a certain extent. High pH values ​​increase the tendency for scale to form. For instance, as pH increases, the solubility of calcium carbonate decreases, eventually causing it to precipitate on the pipe wall surface; some substances, such as silica, have low solubility at low alkalinity. Therefore, the ease with which scale can form in the pipe can be determined by the pH value of the liquid within the pipe; the ease of scale formation is positively correlated with the pH value of the liquid in the pipe.

[0044] For example, TDS (Total Dissolved Solids) is an important indicator for measuring the total amount of dissolved substances in water. The higher the TDS value, the higher the total amount of dissolved substances in the water, and the easier it is for scale to form and precipitate in the pipes. Based on this, the ease with which scale can form in the pipes can be judged by the TDS value of the liquid inside the pipes, and the ease with which scale can form is positively correlated with the TDS value of the liquid inside the pipes.

[0045] For example, based on the pH value of the liquid in the pipe and / or the TDS value of the liquid in the pipe, a scale condensation temperature threshold can be determined. This scale condensation temperature threshold is used to characterize the temperature threshold for scale condensation in the pipe. That is, when the temperature of the liquid in the pipe exceeds the scale condensation temperature threshold, scale is easily condensed and deposited; when the temperature of the liquid in the pipe is less than the scale condensation temperature threshold, scale is not easily condensed and deposited.

[0046] For example, after calculating the above-mentioned scale condensation temperature threshold, a corresponding anti-scaling control strategy can be executed based on the scale condensation temperature threshold and the current temperature of the liquid in the pipe.

[0047] Specifically, step 102 above may also include steps 102b1 to 102b6: Step 102b1: When the temperature of the liquid in the pipe is less than the first preset temperature threshold, increase the operating frequency of the compressor of the water-cooled air conditioner according to the first frequency increase rate.

[0048] Step 102b2: When the temperature of the liquid in the pipe is greater than or equal to the first preset temperature threshold and less than the second preset temperature threshold, the operating frequency of the compressor of the water-cooled air conditioner is increased according to the second frequency increase rate; the second frequency increase rate is less than the first frequency increase rate.

[0049] Step 102b3: When the temperature of the liquid in the pipe is greater than or equal to the second preset temperature threshold and less than the scale condensation temperature threshold, the operating frequency of the compressor remains unchanged; the scale condensation temperature threshold is greater than the second preset temperature threshold.

[0050] Step 102b4: If the temperature of the liquid in the pipe is greater than or equal to the scale condensation temperature threshold and less than the third preset temperature threshold, reduce the operating frequency of the compressor according to the first frequency reduction speed; the third preset temperature threshold is greater than the scale condensation temperature threshold.

[0051] Step 102b5: When the temperature of the liquid in the pipe is greater than or equal to the third preset temperature threshold and less than the fourth preset temperature threshold, the operating frequency of the compressor is reduced according to the second frequency reduction rate; the second frequency reduction rate is greater than the first frequency reduction rate; the fourth preset temperature threshold is greater than the third preset temperature threshold.

[0052] Step 102b6: If the temperature of the liquid in the pipe is greater than or equal to the fourth preset temperature threshold, control the compressor to stop running.

[0053] For example, such as Figure 2As shown, a temperature sensor is added to the water outlet pipe of the water-cooled air conditioner to detect the outlet water temperature Tw (i.e., the temperature of the liquid in the pipe) in real time. Based on the debugging results of the water-cooled air conditioner, multiple temperature points are set for segmented control. When Tw < T1 (i.e., the first preset temperature threshold), it indicates that the current heat exchange is insufficient and the heat exchange efficiency of the tap water is low. At this time, the compressor rapidly increases its frequency to improve heat exchange efficiency. When T1 ≤ Tw < T2 (i.e., the second preset temperature threshold), the compressor slowly increases its frequency. When T2 ≤ Tw < T3 (i.e., the scale buildup...), the compressor... When T3 ≤ Tw < T4 (i.e., the third preset temperature threshold mentioned above), the heat exchange of the tap water is sufficient, and the heat exchange of the tap water is saturated at the current compressor frequency. The outlet water temperature is too high and has reached the condition for scale condensation, so the compressor frequency slowly decreases. When T4 ≤ Tw < T5 (i.e., the fourth preset temperature threshold mentioned above), the heat exchange of the tap water can no longer be met, and the condition for scale condensation is further increased, so the compressor frequency drops rapidly. When Tw ≥ T5, the heat exchange system has failed, and the compressor stops.

[0054] For example, in addition to controlling the temperature of the liquid in the pipe by controlling the compressor frequency to avoid excessive scale buildup and precipitation due to high temperature, a scale protection value can also be calculated by the pH value, TDS value, and temperature of the liquid in the pipe. Based on this scale protection value, it can be determined whether the ultrasonic generator installed on the water-cooled air conditioner needs to be turned on to reduce scale deposition during use.

[0055] Specifically, step 102 above may also include the following steps 102c1 and 102c2: Step 102c1: Calculate the scale protection value by weighting and summing the pH value, TDS value, and temperature of the liquid in the pipe.

[0056] Step 102c2: When the scale protection value is greater than the preset scale protection threshold, control the ultrasonic generator to generate ultrasonic waves to reduce the condensation and precipitation of scale in the pipe.

[0057] Specifically, the scale protection value is calculated based on the following formula: Q = w1 × TDS + w2 × T 温度 +w3×pH (Formula 1)

[0058] Where Q is the scale protection value, w1 is the weight corresponding to the TDS value of the liquid in the pipe, and w2 is the temperature T of the liquid in the pipe. 温度 The corresponding weights are w3, which is the weight corresponding to the pH value of the liquid in the pipe.

[0059] For example, the scale protection value can directly reflect the ease with which scale can form in the pipe. The higher the scale protection value, the easier it is for scale to form in the pipe; conversely, the lower the scale protection value, the less likely scale will form in the pipe.

[0060] For example, when the scale protection value exceeds the preset scale protection threshold, scale is very likely to condense and precipitate in the pipe. At this time, it is necessary to turn on the ultrasonic generator installed on the water-cooled air conditioner to generate ultrasonic waves in order to reduce the condensation and precipitation of scale in the pipe.

[0061] In one possible implementation, the scale protection value curve corresponding to the scale protection value can be used to calculate the cumulative scale amount, and a descaling operation can be performed after the cumulative scale amount reaches a certain level.

[0062] Specifically, step 102 above may also include the following steps 102d1 and 102d2: Step 102d1: Obtain the scale protection value curve, calculate the scale amount based on the outflow volume corresponding to each time period of the scale protection value curve, and calculate the cumulative scale amount based on the scale amount corresponding to each time period.

[0063] Step 102d2: When the accumulated scale exceeds a preset scale threshold, control the ultrasonic generator to generate ultrasonic waves to clean the scale deposited on the inner wall of the pipe.

[0064] For example, the amount of scale in any target time period is calculated based on the following formula:

[0065] Where D is the amount of scale during the target time period, Q1 is the scale protection value corresponding to the start time of the target time period, Q2 is the scale protection value corresponding to the end time of the target time period, T is the total duration of the target time period, and O t The water output during the target time period.

[0066] For example, when the accumulated scale exceeds the preset scale threshold, it indicates that there is a lot of scale condensed and deposited in the pipe. At this time, a descaling operation needs to be performed to remove the scale deposited on the inner wall of the pipe.

[0067] The method for preventing scale buildup in a kitchen water-cooled air conditioner provided in this application embodiment first involves acquiring target parameters of the water-cooled air conditioner during heat exchange. These target parameters include: the pH value of the liquid inside the pipes, the total dissolved solids (TDS) value of the liquid inside the pipes, and the temperature of the liquid inside the pipes. Then, a corresponding scale prevention control strategy is executed based on these target parameters. The ease of scale formation is positively correlated with the pH value of the liquid inside the pipes; the ease of scale formation is positively correlated with the TDS value of the liquid inside the pipes; and the ease of scale formation is positively correlated with the temperature of the liquid inside the pipes. Thus, by rationally controlling the water-cooled air conditioner, scale buildup inside the pipes is reduced, preventing excessive scale buildup from affecting the cooling effect and water flow of the water-cooled air conditioner.

[0068] It should be noted that the kitchen water-cooled air conditioner descaling method provided in this application embodiment can be executed by a kitchen water-cooled air conditioner descaling device, or a control module in the kitchen water-cooled air conditioner descaling device for executing the kitchen water-cooled air conditioner descaling method.

[0076] Where Q is the scale protection value, w1 is the weight corresponding to the TDS value of the liquid in the pipe, and w2 is the temperature T of the liquid in the pipe.温度 The corresponding weights are w3, which is the weight corresponding to the pH value of the liquid in the pipe.

[0080] The anti-scaling device for a kitchen water-cooled air conditioner provided in this application first acquires target parameters of the water-cooled air conditioner during the heat exchange process. These target parameters include: the pH value of the liquid inside the pipes, the total dissolved solids (TDS) value of the liquid inside the pipes, and the temperature of the liquid inside the pipes.
