Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a control method, operation control device, air conditioner, and storage medium for an air conditioner. Background Technology

[0002] For modular air conditioners, such as kitchen air conditioners, the condenser is usually located on the indoor side, resulting in a relatively low airflow on the condenser side, which affects the cooling effect. Typically, a water pump motor is installed in the air conditioner to atomize water and send it to the condenser to assist in heat exchange. However, since the optimal water consumption rate varies under different operating conditions, maintaining a constant output from the water pump motor and water filling device before establishing a relationship between real-time water consumption rate and the optimal rate will result in poor water pumping performance. Consequently, the air conditioner cannot reach its optimal operating state, reducing its cooling effect. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a control method, an operation control device, an air conditioner, and a storage medium for an air conditioner. By adjusting the operating status of the water filling device in a timely manner, the heat exchange efficiency of the condenser can be improved, which is beneficial to increasing the cooling capacity of the air conditioner.

[0004] In a first aspect, embodiments of the present invention provide a control method for an air conditioner, the air conditioner comprising a condenser, a water tray, a water supply device for supplying water to the water tray, and a water pump motor for atomizing the water in the water tray, the control method comprising:

[0005] With the water pump motor and the water filling device turned on, the operating parameters of the condenser are obtained;

[0006] Obtain the water consumption status of the air conditioner;

[0007] The operating status of the water supply device is controlled according to the water consumption status of the air conditioner;

[0008] The step of obtaining the water consumption status of the air conditioner includes calculating the first water consumption on the condenser side based on the operating parameters;

[0009] The air conditioner control method provided by the embodiments of the present invention has at least the following beneficial effects: when the water pump motor and the water filling device are turned on, by acquiring the water consumption status of the air conditioner and controlling the working status of the water filling device according to the water consumption status of the air conditioner, the water pump motor can achieve a better operating state. By acquiring the operating parameters of the condenser and calculating the first water consumption on the condenser side according to the operating parameters, the water consumption status of the air conditioner can be reflected. Adjusting the working status of the water filling device in a timely manner according to the water consumption status of the air conditioner is beneficial to improving the water pumping effect of the water pump motor, thereby improving the heat exchange efficiency of the condenser, ensuring that the air conditioner can always operate in the optimal state, and improving the cooling capacity of the air conditioner.

[0010] In the above-mentioned control method for an air conditioner, the operating parameters include the air velocity passing through the condenser, the first temperature and first relative humidity on the air inlet side of the condenser, and the second temperature and second relative humidity on the air outlet side of the condenser. The calculation of the first water consumption on the condenser side based on the operating parameters includes:

[0011] The first moisture content on the air inlet side of the condenser is obtained based on the first temperature and the first relative humidity.

[0012] The second moisture content on the air outlet side of the condenser is obtained based on the second temperature and the second relative humidity.

[0013] The first water consumption on the condenser side is calculated based on the wind speed, the first moisture content, and the second moisture content.

[0014] By obtaining the first temperature and the first relative humidity on the air inlet side of the condenser, the first moisture content on the air inlet side of the condenser can be obtained. By obtaining the second temperature and the second relative humidity on the air outlet side of the condenser, the second moisture content on the air outlet side of the condenser can be obtained. In addition, the air velocity passing through the condenser is obtained, and the first water consumption on the condenser side is calculated by combining the first moisture content and the second moisture content. That is, the actual water consumption on the condenser side of the air conditioner under the current operating state can be obtained, thereby reflecting the actual cooling effect of the condenser.

[0015] In the above-mentioned control method for an air conditioner, obtaining the water consumption status of the air conditioner further includes obtaining a second water consumption of the air conditioner, wherein the second water consumption is obtained according to the following method:

[0016] The first heat exchange and the second heat exchange of the condenser are obtained, wherein the first heat exchange is the required heat exchange of the condenser when the air conditioner is in its optimal operating state, and the second heat exchange is the heat that the air on the condenser side can carry away;

[0017] The third heat exchange of the water pumping device is calculated based on the first heat exchange and the second heat exchange.

[0018] The second water consumption is calculated based on the third heat exchange.

[0019] It should be noted that the first and second heat exchange rates can be calculated based on the operating parameters of the air conditioner, and the third heat exchange rate of the water pumping device can be calculated based on the first and second heat exchange rates. The third heat exchange rate represents the heat that the water pumping device needs to remove. The second water consumption can be calculated based on the third heat exchange rate. By comparing the first and second water consumption, the working state of the water pumping device can be controlled, thereby improving the heat exchange efficiency of the condenser.

[0020] In the above-described control method for an air conditioner, controlling the operating state of the water supply device based on the water consumption status of the air conditioner includes at least one of the following:

[0021] When the first water consumption is greater than the second water consumption, the water supply device is controlled to reduce the water replenishment rate;

[0022] When the first water consumption is less than the second water consumption, the water supply device is controlled to increase the water replenishment rate;

[0023] When the first water consumption equals the second water consumption, the water supply device is controlled to maintain its current operating state.

[0024] By comparing the first and second water consumption, the water replenishment speed of the water supply device is adjusted. The water pumping motor can achieve the optimal water pumping effect under the same power consumption, resulting in better cooling effect of the condenser. This allows the air conditioner to always operate in the optimal state, which is conducive to improving the cooling capacity of the air conditioner.

[0025] In the control method of the above-mentioned air conditioner, the water filling device includes a solenoid valve or a water pump;

[0026] When the water supply device includes a solenoid valve, the water supply speed can be reduced or increased by controlling the opening degree of the solenoid valve;

[0027] When the water supply device includes a water pump, the pumping speed of the water pump can be controlled to decrease or increase the water supply speed.

[0028] It should be noted that the water supply device includes a solenoid valve or a water pump. The water supply speed can be adjusted by controlling the opening of the solenoid valve or the pump speed of the water pump, thereby adjusting the water consumption on the condenser side. This helps to improve the water pumping effect of the water pumping motor, thereby improving the cooling effect of the condenser.

[0029] In the above-mentioned control method for an air conditioner, when the water filling device includes a solenoid valve, the water filling device further includes a booster pump and a water supply pipe connected to the water receiving pan, and both the booster pump and the solenoid valve are located on the water supply pipe, the control method further includes:

[0030] Obtain the water supply pressure inside the water pipe;

[0031] The operating status of the booster pump is controlled according to the water supply pressure.

[0032] It should be noted that the booster pump is used to increase the water pressure. By obtaining the water pressure in the water supply pipe, it is possible to determine whether the water supply pressure meets the water filling requirements. By controlling the working state of the booster pump through the water supply pressure, it is possible to ensure that the water supply pressure is within a suitable water pressure range, meet the water filling needs of the condenser side, and improve the reliability of the water filling device.

[0033] In the above-mentioned control method for the air conditioner, the step of controlling the operating state of the booster pump according to the water supply pressure includes:

[0034] When the water supply pressure is lower than the preset water pressure, the booster pump is turned on.

[0035] By comparing the supply water pressure with the preset water pressure, if the supply water pressure is lower than the preset water pressure, it means that the current supply water pressure does not meet the water filling requirements. In this case, the booster pump is turned on to increase the supply water pressure and ensure that the supply water pressure meets the requirements.

[0036] The control method for the aforementioned air conditioner also includes:

[0037] After running for a preset time, the operating parameters of the condenser side are obtained again and the first water consumption is recalculated.

[0038] By controlling the working state of the water supply device according to the first water consumption and then keeping the air conditioner running continuously for a preset time, the operating parameters on the condenser side can be obtained again and the first water consumption can be recalculated. The working state of the water supply device can be controlled again, and the working state of the water supply device can be adjusted in real time. This helps to improve the flexibility and accuracy of air conditioner control, thereby improving the energy efficiency of the air conditioner.

[0039] In a second aspect, embodiments of the present invention provide an operation control device, including at least one control processor and a memory for communicatively connecting to the at least one control processor; the memory stores instructions executable by the at least one control processor, the instructions being executed by the at least one control processor to enable the at least one control processor to perform the air conditioner control method as described in the first aspect embodiment above.

[0040] The operation control device provided by the embodiments of the present invention has at least the following beneficial effects: when the water pump motor and the water filling device are turned on, by acquiring the water consumption status of the air conditioner and controlling the working status of the water filling device according to the water consumption status of the air conditioner, the water pump motor can achieve a better operating state. By acquiring the operating parameters of the condenser and calculating the first water consumption on the condenser side according to the operating parameters, the water consumption status of the air conditioner can be reflected. Adjusting the working status of the water filling device in a timely manner according to the water consumption status of the air conditioner is beneficial to improving the water pumping effect of the water pump motor, thereby improving the heat exchange efficiency of the condenser, ensuring that the air conditioner can always operate in the optimal state, and improving the cooling capacity of the air conditioner.

[0041] Thirdly, embodiments of the present invention provide an air conditioner including the operation control device described in the second aspect of the embodiments above.

[0042] The air conditioner provided by the embodiments of the present invention has at least the following beneficial effects: when the water pump motor and the water filling device are turned on, by acquiring the water consumption status of the air conditioner and controlling the working status of the water filling device according to the water consumption status of the air conditioner, the water pump motor can achieve a better operating state. By acquiring the operating parameters of the condenser and calculating the first water consumption on the condenser side according to the operating parameters, the water consumption status of the air conditioner can be reflected. Adjusting the working status of the water filling device in a timely manner according to the water consumption status of the air conditioner is beneficial to improving the water pumping effect of the water pump motor, thereby improving the heat exchange efficiency of the condenser, ensuring that the air conditioner can always operate in the optimal state, and improving the cooling capacity of the air conditioner.

[0043] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing computer-executable instructions for causing a computer to perform the air conditioner control method described in the first aspect embodiment above.

[0044] The computer-readable storage medium provided in the embodiments of the present invention has at least the following beneficial effects: when the water pump motor and the water filling device are turned on, by acquiring the water consumption status of the air conditioner and controlling the working status of the water filling device according to the water consumption status of the air conditioner, the water pump motor can achieve a better operating state. By acquiring the operating parameters of the condenser and calculating the first water consumption on the condenser side according to the operating parameters, the water consumption status of the air conditioner can be reflected. Adjusting the working status of the water filling device in a timely manner according to the water consumption status of the air conditioner is beneficial to improving the water pumping effect of the water pump motor, thereby improving the heat exchange efficiency of the condenser, ensuring that the air conditioner can always operate in the optimal state, and improving the cooling capacity of the air conditioner.

[0057] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0058] It should be understood that in the description of the embodiments of the present invention, the use of terms such as "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated. "At least one" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself, and "several" means one or more, unless otherwise explicitly specified.

[0059] Furthermore, unless otherwise explicitly specified and limited, the term "connection / linkage" should be interpreted broadly. For example, it can be a fixed or movable connection, a detachable or non-detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between them; it can be a direct connection or an indirect connection through an intermediate medium. It should be noted that although a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown in the flowchart.

[0060] It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0061] The air conditioner control method, operation control device, air conditioner and storage medium provided in the embodiments of the present invention can improve the heat exchange efficiency of the condenser by timely adjusting the working state of the water filling device, which is beneficial to increasing the cooling capacity of the air conditioner.

[0062] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0063] like Figure 1 and Figure 2 As shown, the air conditioner of this embodiment of the invention is provided with a condenser 100, a water tray 200, a water filling device 300, and a water pumping motor 400. The water tray 200 is located below the condenser 100, the water pumping motor 400 is installed in the water tray 200, and the water filling device 300 can be connected to a water source to supply water to the water tray 200 for use by the water pumping motor 400. The water pumping motor 400 atomizes the water in the water tray 200 and sends it to the condenser 100 for auxiliary heat exchange.

[0064] It should be noted that after the air conditioner's refrigeration system starts, the compressor 500 draws in the refrigerant vapor from the evaporator 600 and compresses it to the condensing pressure before supplying it to the condenser 100. The condenser 100 condenses the high-pressure refrigerant vapor from the compressor 500 into refrigerant liquid, and heat exchange occurs during the condensation process. The refrigerant liquid is then throttled and depressurized by the throttling device 700 before entering the evaporator 600, where it absorbs heat and evaporates, turning into a gas. It then enters the compressor 500 for compression, transforming into a high-temperature, high-pressure gas, before entering the condenser 100 again for heat exchange. This cycle continues, forming the refrigerant flow path. It should be noted that during the condensation process, the refrigerant vapor in the condenser 100 releases heat and needs to be cooled by water or air. By setting up a water supply device 300, sufficient water can be provided to the water pump motor 400. The water pump motor 400 atomizes the water and exchanges heat with the condenser 100, which can improve the cooling effect of the condenser 100. In addition, multiple water pump motors 400 can be set up to improve the heat exchange efficiency of the condenser 100.

[0065] It will be understood by those skilled in the art that Figure 1 and Figure 2 The air conditioner shown in the figure does not constitute a limitation on the embodiments of the present invention, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0066] like Figure 3 As shown, based on the above Figure 1 or Figure 2 An embodiment of the first aspect of the present invention provides a control method for an air conditioner, including but not limited to steps S110 to S130:

[0067] Step S110: With the water pump motor and water filling device turned on, obtain the operating parameters of the condenser.

[0068] It should be noted that after the air conditioner is turned on, the user selects either cooling or dehumidification mode. The cooling system then starts, and the compressor operates at the target frequency to ensure normal operation. When the water pump and water filling device are on, the water filling device continuously supplies water to the drip tray, and the water pump continuously consumes water from the drip tray, thus assisting in condenser cooling and increasing the air conditioner's cooling capacity. The condenser's operating parameters can be temperature, humidity, fan speed, airflow direction, operating time, or other applicable parameters.

[0069] Step S120: Obtain the water consumption status of the air conditioner.

[0070] The water consumption status of the air conditioner obtained in S120 includes:

[0071] The first water consumption on the condenser side is calculated based on the operating parameters.

[0072] It should be noted that the first water consumption is the actual water consumption on the condenser side, which can reflect the water pumping effect of the pumping motor. By obtaining the operating parameters of the condenser and calculating the first water consumption based on the operating parameters, the actual cooling effect of the condenser can be determined.

[0073] Step S130: Control the working status of the water filling device according to the water consumption status of the air conditioner.

[0074] The operating status of the water supply device can be controlled by monitoring the water consumption of the air conditioner. For example, the water replenishment speed of the water supply device can be adjusted to ensure that the water pump motor operates with an appropriate water volume, so that the water pump motor can achieve a better water pumping effect, ensuring a good cooling effect of the condenser, which is conducive to improving the cooling effect of the air conditioner and thus improving the energy efficiency of the air conditioner.

[0075] The air conditioner control method provided in the first aspect embodiment above obtains the water consumption status of the air conditioner and controls the working state of the water filling device according to the water consumption status of the air conditioner, so that the water pumping motor can achieve a better operating state. By obtaining the operating parameters of the condenser and calculating the first water consumption on the condenser side according to the operating parameters, the water consumption status of the air conditioner can be reflected. Adjusting the working state of the water filling device in a timely manner according to the water consumption status of the air conditioner is beneficial to improving the water pumping effect of the water pumping motor, thereby improving the heat exchange efficiency of the condenser, ensuring that the air conditioner can always operate in the optimal state, and thus improving the cooling capacity of the air conditioner.

[0076] like Figure 4 As shown, the control method for the air conditioner described above also includes, but is not limited to, steps S210 and S220:

[0077] Step S210: Obtain the current water level in the water receiving tray;

[0078] Step S220: Control the working status of the water supply device according to the current water level.

[0079] Because the rate at which an air conditioner consumes water varies under different operating conditions, the current water level in the drip tray will also change. By detecting the current water level in the drip tray and controlling the operation of the water filling device, it is possible to ensure that the current water level is always kept within a suitable range, so that the water pumping motor can maintain a better water pumping effect, which is beneficial to improving the heat exchange efficiency of the condenser.

[0080] like Figure 1 or Figure 2As shown, it should be noted that a water level switch 210 can be installed on the water receiving pan 200. The water level switch 210 is used to detect the current water level in the water receiving pan 200.

[0081] In the above-mentioned control method for the air conditioner, step S220, which controls the operating state of the water supply device according to the current water level, includes:

[0082] When the current water level is greater than or equal to the preset water level, the water supply device will be shut off.

[0083] It should be noted that the preset water level is the limit water level of the drip tray. As the water supply device continuously supplies water to the drip tray, overflow may easily occur. By comparing the current water level with the preset water level, if the current water level is greater than or equal to the preset water level, it means that the water level in the drip tray has reached the limit water level and there is a risk of water overflowing. In this case, the water supply device will be shut off, while the water pump motor will continue to work normally, continuously consuming the water in the drip tray, thereby reducing the current water level in the drip tray and preventing water overflow, thus ensuring the stability of the air conditioner's operation.

[0084] Understandably, when the current water level in the receiving pan reaches the preset water level, by keeping the water pump motor on while controlling the water filling device to be off, that is, by adopting a water-full protection control logic that only consumes water and does not replenish water when the water level is limited, the water consumption in the receiving pan can be accelerated, thereby reducing the current water level in the receiving pan to a suitable water level range.

[0085] like Figure 1 or Figure 2 As shown, specifically, the water filling device 300 may include a solenoid valve 210 or a water pump 220. When the water is full, if the water filling device 300 includes a solenoid valve 210, by closing the solenoid valve 210 and keeping the water pump 400 on, the current water level in the water receiving tray 200 can be reduced. Similarly, if the water filling device 300 includes a water pump 220, by controlling the water pump 220 to be closed and keeping the water pump 400 on, the possibility of water overflow can be effectively avoided.

[0086] like Figure 5 As shown, in the above-mentioned control method for an air conditioner, the operating parameters include the air velocity passing through the condenser, the first temperature and first relative humidity on the condenser inlet side, and the second temperature and second relative humidity on the condenser outlet side. Step S120 calculates the first water consumption on the condenser side based on the operating parameters, including but not limited to steps S310 to S330:

[0087] Step S310: Obtain the first moisture content on the air inlet side of the condenser based on the first temperature and the first relative humidity;

[0088] Step S320: Obtain the second moisture content on the condenser outlet side based on the second temperature and the second relative humidity;

[0089] It should be noted that relative humidity refers to the ratio of the partial pressure of water vapor in moist air to the partial pressure of water vapor in saturated moist air at the same temperature. Moisture content, also known as specific humidity, refers to the mass of water vapor contained in 1 kg of dry air.

[0090] It is understandable that the first temperature and the first relative humidity are the condenser's inlet air temperature and inlet air relative humidity, respectively, and the first moisture content represents the condenser's inlet air moisture content. The second temperature and the second relative humidity are the condenser's exhaust air temperature and exhaust air relative humidity, respectively, and the second moisture content represents the condenser's exhaust air moisture content.

[0091] It should be noted that the first moisture content corresponding to the first temperature and the first relative humidity can be determined based on the preset relationship data between the preset temperature, the preset relative humidity, and the preset moisture content. Similarly, the second moisture content corresponding to the second temperature and the second relative humidity can be determined based on the above preset relationship data. For example, the moisture content can be obtained through a curve or a lookup table, and no specific restrictions are made here.

[0092] Step S330: Calculate the first water consumption on the condenser side based on the wind speed, the first moisture content, and the second moisture content.

[0093] By obtaining the first temperature and the first relative humidity on the air inlet side of the condenser, the first moisture content on the air inlet side of the condenser can be obtained. By obtaining the second temperature and the second relative humidity on the air outlet side of the condenser, the second moisture content on the air outlet side of the condenser can be obtained. In addition, the air velocity passing through the condenser is obtained, and the first water consumption on the condenser side is calculated by combining the first moisture content and the second moisture content. That is, the actual water consumption on the condenser side of the air conditioner under the current operating state can be obtained, thereby reflecting the actual cooling effect of the condenser.

[0094] Specifically, the first water consumption can be calculated using the following formula:

[0095] m water =M air ×(d p -d4);

[0096] Where, m water d4 represents the first water consumption; d4 represents the first moisture content, which can be obtained from the condenser inlet air temperature T4 and inlet air relative humidity RH4; d p The second moisture content can be determined by the condenser exhaust air temperature T. P relative humidity (RH) of exhaust air P Get; M airThe air mass flow rate of the condenser can be represented by outdoor air parameters and air volume flow rate V. air Calculated; V air The air volumetric flow rate of the condenser can be obtained by looking up the condenser fan speed, V. air There is a corresponding relationship with wind speed.

[0097] By obtaining the moisture content on the inlet and outlet sides of the condenser and combining it with the collected wind speed, the first water consumption on the condenser side can be calculated. The calculation method is simple and reliable.

[0098] It should be noted that temperature sensors can be installed on the air inlet and outlet sides of the condenser to detect the first and second temperatures, and humidity sensors can be installed on the air inlet and outlet sides of the condenser to detect the first and second relative humidity. In addition, a flow sensor can be installed on the air outlet side of the condenser to detect the wind speed passing through the condenser. This embodiment of the invention does not impose specific restrictions on the detection method of the operating parameters.

[0099] like Figure 6 As shown, in the above-mentioned control method for the air conditioner, the step S120 of obtaining the water consumption status of the air conditioner also includes obtaining the second water consumption of the air conditioner. It should be noted that the second water consumption refers to the theoretical water consumption value of the air conditioner when it is in the best operating state under the current internal and external environment and the user-set temperature parameters. At this time, the water pumping motor can achieve the optimal water pumping effect.

[0100] The second water consumption can be obtained in the following way:

[0101] Step S410: Obtain the first heat exchange and the second heat exchange of the condenser, wherein the first heat exchange is the heat exchange required by the condenser of the air conditioner under optimal operating conditions, and the second heat exchange is the heat that the air on the condenser side can carry away.

[0102] Step S420: Calculate the third heat exchange of the water pumping device based on the first and second heat exchange amounts;

[0103] Step S430: Calculate the second water consumption based on the third heat exchange.

[0104] It should be noted that the first and second heat exchange rates can be calculated based on the operating parameters of the air conditioner, and the third heat exchange rate of the water pumping device can be calculated based on the first and second heat exchange rates. The third heat exchange rate represents the heat that the water pumping device needs to remove. The second water consumption can be calculated based on the third heat exchange rate. By comparing the first and second water consumption, the working state of the water pumping device can be controlled, thereby improving the heat exchange efficiency of the condenser.

[0105] It should be noted that the second water consumption can be a fixed value or a range value. The operating parameters of the air conditioner may include, but are not limited to, cooling output, compressor frequency, evaporator-side airflow, condenser-side airflow, indoor and outdoor ambient temperature, etc.

[0106] Specifically, the first heat exchange can be calculated using the following formula:

[0107] Q3 = Q1 + aP;

[0108] Where Q3 represents the first heat exchange, which is the heat exchange required by the condenser of the air conditioner under optimal operating conditions; Q1 represents the cooling output demand, which can be determined based on the indoor ambient temperature T1 and the user-set temperature T. S The difference determines the actual output requirement; P is the compressor power, which can be determined based on indoor ambient temperature T1, indoor ambient humidity RH1, outdoor ambient temperature T4, and compressor operating frequency F. r The query revealed that 'a' is a coefficient less than 1, representing the proportion of compressor power P converted into refrigerant heat.

[0109] It is understandable that the first heat exchange is obtained by acquiring the cooling output demand and compressor power, and then calculating the cooling output demand and compressor power.

[0110] The second heat exchanger can be calculated using the following formula:

[0111] Q air =M air ×(h5-h4);

[0112] Among them, Q air This indicates the second heat exchange, which is the heat that the air on the condenser side can carry away; M air The air mass flow rate of the condenser can be represented by the outdoor air parameters and the air volume flow rate V of the condenser. air Calculated; V air h5 represents the air volumetric flow rate of the condenser, which can be obtained by looking up the condenser fan speed; h5 represents the condenser exhaust specific enthalpy, which can be calculated based on the inlet air moisture content d4 and the condenser exhaust preset temperature T5; h4 represents the condenser inlet specific enthalpy, which can be calculated based on the outdoor ambient temperature T4 and the outdoor ambient humidity RH4.

[0113] It is understandable that the second heat exchange is obtained by acquiring the air mass flow rate of the condenser, the exhaust air specific enthalpy of the condenser, and the inlet air specific enthalpy of the condenser, and then calculating the heat exchange based on these parameters.

[0114] The third heat exchanger can be calculated using the following formula:

[0115] Q water =Q3-Qair ;

[0116] Among them, Q water Q represents the third heat exchange, which is the heat that the water pumping device needs to remove; Q3 represents the first heat exchange; Q air Indicates the second heat exchange;

[0117] The second water consumption can be calculated using the following formula:

[0118] M water =Q water ÷q water ÷b;

[0119] Among them, M water Indicates the second water consumption; Q water Indicates the third heat exchange; q water 1 is the latent heat of the air conditioner under the current operating conditions, which represents the latent heat of vaporization of water when it turns into water vapor at one atmosphere of pressure; b is the water consumption coefficient, which is a value less than 1. It is obtained through experimental testing and represents the ratio of the heat absorbed by the condenser when 1 kg of water evaporates to the latent heat of vaporization of 1 kg of water during actual use.

[0120] Understandably, the second water consumption can be calculated based on the third heat exchange, latent heat, and water consumption coefficient.

[0121] It should be noted that the embodiments of the present invention do not impose specific restrictions on the calculation method of the second water consumption. Those skilled in the art can select appropriate parameters and calculation methods according to specific circumstances to obtain the second water consumption. In addition, the outdoor ambient temperature used in the above calculation process refers to the air inlet temperature of the condenser.

[0122] By obtaining the second water consumption of the air conditioner and comparing the first water consumption with the second water consumption, the working state of the water supply device can be controlled. For example, the water supply speed of the water supply device can be adjusted according to the first water consumption and the second water consumption, so that the water pumping motor can always maintain a better water pumping effect, thereby making the heat exchange efficiency of the condenser higher.

[0123] In the above-mentioned control method for the air conditioner, step S130, which controls the operating state of the water supply device according to the water consumption status of the air conditioner, includes at least one of the following:

[0124] When the first water consumption is greater than the second water consumption, control the water supply device to reduce the water replenishment rate;

[0125] When the first water consumption is less than the second water consumption, control the water supply device to increase the water replenishment rate;

[0126] When the first water consumption equals the second water consumption, the water supply device is controlled to maintain its current operating state.

[0127] It should be noted that the second water consumption is the ideal water consumption of the air conditioner under the current operating state. If the first water consumption is greater than the second water consumption, it means that the water consumption on the condenser side exceeds the optimal value. In this case, the water supply device is controlled to reduce the water supply speed to reduce the water consumption on the condenser side. If the first water consumption is less than the second water consumption, it means that the water consumption on the condenser side is lower than the optimal value, and the cooling effect of the condenser is insufficient. In this case, the water supply device is controlled to increase the water supply speed to increase the water consumption on the condenser side. If the first water consumption is equal to the second water consumption, it means that the water consumption on the condenser side has reached the optimal value. In this case, the water supply device maintains its current operating state and works normally. By comparing the first water consumption and the second water consumption, the water supply speed of the water supply device is adjusted. The water pump motor can achieve the optimal water pumping effect under the same power consumption, making the cooling effect of the condenser better. This allows the air conditioner to always operate in the optimal state, which is beneficial to improving the cooling capacity of the air conditioner.

[0128] like Figure 1 and Figure 2 As shown, in the above-mentioned control method for the air conditioner, the water filling device 300 includes a solenoid valve 210 or a water pump 220.

[0129] When the water supply device 300 includes a solenoid valve 210, the water supply speed can be reduced or increased by controlling the opening degree of the solenoid valve 210.

[0130] When the water supply device 300 includes a water pump 220, the water supply speed can be reduced or increased by controlling the pumping speed of the water pump 220.

[0131] It should be noted that the water supply device 300 includes a solenoid valve 210 or a water pump 220. The water supply speed can be adjusted by controlling the opening of the solenoid valve 210 or the speed of the water pump 220, thereby adjusting the water consumption on the condenser 100 side. This is beneficial to improving the water pumping effect of the water pumping motor 400, thereby improving the cooling effect of the condenser 100.

[0132] If the water supply device 300 includes a solenoid valve 210, the water supply speed can be reduced or increased by adjusting the opening of the solenoid valve 210. Specifically, if the first water consumption is greater than the second water consumption, the water supply speed can be reduced by decreasing the opening of the solenoid valve 210, thereby reducing the water supply flow. If the first water consumption is less than the second water consumption, the water supply speed can be increased by increasing the opening of the solenoid valve 210, thereby increasing the water supply flow. If the first water consumption is equal to the second water consumption, the solenoid valve 210 maintains its current opening and continues to operate, that is, the solenoid valve 210 maintains its current operating state.

[0133] If the water supply device 300 includes a water pump 220, the water supply speed can be reduced or increased by adjusting the pumping speed of the water pump 220. Specifically, if the first water consumption is greater than the second water consumption, the water supply speed of the water pump 220 is reduced to decrease the water supply speed. If the first water consumption is less than the second water consumption, the water supply speed of the water pump 220 is increased to increase the water supply speed. If the first water consumption is equal to the second water consumption, the water pump 220 continues to operate at the current pumping speed, that is, the water pump 220 maintains its current operating state.

[0134] like Figure 1 and Figure 7 As shown, in the above-mentioned control method for the air conditioner, when the water filling device 300 includes a solenoid valve 210, the water filling device 300 also includes a booster pump 240 and a water supply pipe 230 connected to the water receiving pan 200, the booster pump 240 and the solenoid valve 210 are both located in the water supply pipe 230, and the control method also includes, but is not limited to, steps S510 and S520:

[0135] Step S510: Obtain the water supply pressure in the water pipe;

[0136] Step S520: Control the working status of the booster pump according to the water supply pressure.

[0137] It should be noted that the booster pump 240 is used to increase the water pressure. By obtaining the water supply pressure in the water supply pipe 230, it is possible to determine whether the water supply pressure meets the water filling requirements. By controlling the working state of the booster pump 240 through the water supply pressure, it is possible to ensure that the water supply pressure is within a suitable water pressure range, meet the water filling requirements on the condenser 100 side, and improve the reliability of the water filling device 300.

[0138] In the above-mentioned control method for the air conditioner, step S520, which controls the operating state of the booster pump based on the water supply pressure, includes:

[0139] When the water supply pressure is lower than the preset water pressure, the booster pump will be turned on.

[0140] By comparing the supply water pressure with the preset water pressure, if the supply water pressure is lower than the preset water pressure, it means that the current supply water pressure does not meet the water filling requirements. In this case, the booster pump is turned on to increase the supply water pressure and ensure that the supply water pressure meets the requirements.

[0141] It should be noted that if the water supply pressure is greater than or equal to the preset water pressure, it means that the current water supply pressure meets the water filling requirements, and the booster pump does not need to be turned on.

[0142] The control method for the air conditioner described above also includes the following steps:

[0143] After the preset running time, the operating parameters on the condenser side are retrieved again and the first water consumption is recalculated.

[0144] It should be noted that by controlling the working state of the water addition device according to the first water consumption and then keeping the air conditioner running continuously for a preset time, the operating parameters on the condenser side can be obtained again, the first water consumption can be recalculated, and the working state of the water addition device can be controlled again, so as to adjust the working state of the water addition device in real time, which is beneficial to improving the flexibility and accuracy of the air conditioner control, thereby improving the energy efficiency of the air conditioner.

[0145] To more clearly elaborate on the control method of the air conditioner of the present invention, the following will be further introduced with two overall embodiments.

[0146] As Figure 8 shown, when the water addition device includes a solenoid valve, the control method of the air conditioner of the present invention is specifically as follows:

[0147] 1. Power on;

[0148] 2. Select the cooling (dehumidification) mode; when the air conditioner is turned on, the user selects the operating mode of the air conditioner as "cooling mode" or "dehumidification mode";

[0149] 3. Start the refrigeration system, and set the target frequency of the compressor to FRs; …

[0150] 4. Detect the wind speed v of the condenser, the first temperature T4 and the first relative humidity RH4 on the air inlet side of the condenser, the second temperature T P and the second relative humidity RH P , the current water level height h of the water in the water receiving tray, the water supply pressure P, and keep the water pumping motor and the water addition device in the current on state;

[0151] 5. Compare the water supply pressure P with the preset water pressure P1; if P < P1, it means that the water supply pressure does not meet the water addition requirement, and the booster pump is turned on to ensure that the water supply pressure meets the water addition demand, and step 6 is executed; if P ≥ P1, it means that the water supply pressure meets the water addition requirement, and the booster pump does not need to be turned on, and step 6 is executed;

[0152] 6. Compare the current water level height h with the preset water level height H; if h ≥ H, at this time the current water level height has exceeded the limit water level, and there is a risk of water overflow. Keep the water pumping motor on, and at the same time close the solenoid valve. After running for t time, return to step 4; if h < H, then execute step 7;

[0153] 7. Calculate the first moisture content d4 and the second moisture content d p ; obtain the first moisture content on the air inlet side of the condenser through the first temperature T4 and the first relative humidity RH4, and obtain the second moisture content on the air outlet side of the condenser through the second temperature T P and the second relative humidity RH P ;

[0154] 8. Calculate the first water consumption m on the condenser side based on the wind speed v of the condenser, the first moisture content d4, and the second moisture content d p , and calculate the first water consumption m on the condenser side;

[0155] 9. Calculate or query the second water consumption M based on the operating parameters of the air conditioner in the current operating state;

[0156] 10. Compare the magnitudes of m and M; if m > M, execute step 11; if m = M, execute step 12; if m < M, execute step 13;

[0157] 11. Decrease the opening degree of the solenoid valve; at this time, the first water consumption exceeds the optimal value. By reducing the opening degree of the solenoid valve, the water replenishment speed is decreased. After running for t time, return to step 4;

[0158] 12. Maintain the current operating state; at this time, the first water consumption has reached the optimal value. The solenoid valve maintains the current opening degree and continues to operate, while the entire machine maintains the current operating state. After running for t time, return to step 4;

[0159] 13. Increase the opening degree of the solenoid valve; at this time, the first water consumption is lower than the optimal value, and the cooling effect of the condenser is insufficient. By increasing the opening degree of the solenoid valve, the water replenishment speed is increased, thereby adjusting the water consumption. After running for t time, return to step 4.

[0160] As Figure 9 shown, when the water addition device includes a water pump, the control method of the air conditioner of the present invention is specifically as follows:

[0161] 1. Power on;

[0162] 2. Select the cooling (dehumidification) mode;

[0163] 3. Start the refrigeration system, and set the target frequency of the compressor to FRs;

[0165] 5. Compare the magnitudes of the current water level height h and the preset water level height H; if h ≥ H, at this time, the current water level height has exceeded the limit water level, and there is a risk of water overflow. Keep the water pumping motor on, and at the same time, turn off the water pump. After running for t time, return to step 4; if h < H, then execute step 6;

[0166] 6. Calculate the first moisture content d4 and the second moisture content d p; Obtain the first moisture content on the air inlet side of the condenser based on the first temperature T4 and the first relative humidity RH4, and obtain the second moisture content on the air outlet side of the condenser based on the second temperature T P and the second relative humidity RH P ;

[0167] 7. Calculate the first water consumption m on the condenser side according to the wind speed v of the condenser, the first moisture content d4, and the second moisture content d p ;

[0168] 8. Calculate or query the second water consumption M according to the operating parameters of the air conditioner in the current operating state;

[0169] 9. Compare the magnitudes of m and M; if m > M, execute step 10; if m = M, execute step 11; if m < M, execute step 12;

[0170] 10. Reduce the water pumping speed of the water pump; at this time, the first water consumption exceeds the optimal value. By reducing the water pumping speed of the water pump, the water replenishment speed is decreased. After operating for t time, return to step 4;

[0171] 11. Maintain the current operating state; at this time, the first water consumption has reached the optimal value. The water pump continues to operate at the current water pumping speed, and the entire unit maintains the current operating state. After operating for t time, return to step 4;

[0172] 12. Increase the water pumping speed of the water pump; at this time, the first water consumption is lower than the optimal value, and the cooling effect of the condenser is insufficient. By increasing the water pumping speed of the water pump, the water replenishment speed is increased, thereby adjusting the water consumption. After operating for t time, return to step 4.

[0173] As Figure 10 shown, an embodiment of the second aspect of the present invention provides an operation control device 1000, including at least one control processor 1010 and a memory 102 connecting to communicate with at least one control processor 1010; the control processor 1010 and the memory 1020 can be connected through a bus or other means, Figure 10 and an example of connection through a bus is shown. The memory 1020 stores instructions executable by at least one control processor 1010. The instructions are executed by at least one control processor 1010, so that at least one control processor 1010 can execute the control method of the air conditioner in the first aspect embodiment as described above. For example, execute the method steps S110 to S130 described above, Figure 3 the method steps S210 and S220 in Figure 4 , Figure 5 the method steps S310 to S330 in Figure 6 , Figure 7Method steps S510 and S520, and Figure 8 and Figure 9 The method and steps are as follows: When the water pump motor and water filling device are turned on, the water consumption status of the air conditioner is acquired, and the working status of the water filling device is controlled according to the water consumption status of the air conditioner, so that the water pump motor can achieve a better operating state. By acquiring the operating parameters of the condenser and calculating the first water consumption on the condenser side according to the operating parameters, the water consumption status of the air conditioner can be reflected. Adjusting the working status of the water filling device in a timely manner according to the water consumption status of the air conditioner is beneficial to improving the water pumping effect of the water pump motor, thereby improving the heat exchange efficiency of the condenser, ensuring that the air conditioner can always operate in the optimal state, and thus improving the cooling capacity of the air conditioner.

[0174] A third aspect of the present invention provides an air conditioner including the operation control device described in the second aspect embodiment above. The air conditioner of this embodiment, when the water pump motor and water filling device are turned on, acquires the water consumption status of the air conditioner and controls the operating status of the water filling device based on the water consumption status, enabling the water pump motor to achieve a better operating state. By acquiring the operating parameters of the condenser and calculating the first water consumption on the condenser side based on the operating parameters, the water consumption status of the air conditioner can be reflected. Timely adjustment of the operating status of the water filling device based on the water consumption status of the air conditioner helps improve the water pumping effect of the water pump motor, thereby improving the heat exchange efficiency of the condenser and ensuring that the air conditioner always operates in an optimal state, which is beneficial to increasing the cooling capacity of the air conditioner.

Figure 3 Method steps S110 to S130 in the text Figure 4 Method steps S210 and S220 in the text Figure 5 Method steps S310 to S330 in the text Figure 6 Method steps S410 to S430, Figure 7 Method steps S510 and S520, and Figure 8 and Figure 9The method and steps are as follows: When the water pump motor and water filling device are turned on, the water consumption status of the air conditioner is acquired, and the working status of the water filling device is controlled according to the water consumption status of the air conditioner, so that the water pump motor can achieve a better operating state. By acquiring the operating parameters of the condenser and calculating the first water consumption on the condenser side according to the operating parameters, the water consumption status of the air conditioner can be reflected. Adjusting the working status of the water filling device in a timely manner according to the water consumption status of the air conditioner is beneficial to improving the water pumping effect of the water pump motor, thereby improving the heat exchange efficiency of the condenser, ensuring that the air conditioner can always operate in the optimal state, and thus improving the cooling capacity of the air conditioner.
