DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0054] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0055] With the development of modern industry, clean workshops have increasingly stringent requirements for production environments, especially the need to maintain constant temperature and humidity conditions to ensure product quality and production efficiency.

[0056] At present, in order to ensure that the clean workshop can maintain a constant temperature and humidity environment, a high-efficiency air-conditioning system is installed in the clean workshop. The air-conditioning system controls the humidity through a surface cooling heat exchanger and controls the temperature through a heating heat exchanger. This method may cause the air-conditioning system to consume more energy during operation or cause abnormal indoor temperature.

[0057] For example, in the case of high energy consumption during the operation of the air conditioning system: Assume that the user sets the indoor temperature to 24°C and the humidity to 60% (humidity content is 11.3g / kg). If the temperature of the return air main is 21°C and the humidity is 65% (humidity content is 10.2g / kg), according to the existing control logic, since the humidity of the return air main has not reached the set value, the valve of the surface cooling heat exchanger will be opened for cooling and dehumidification, and at the same time, the valve of the heating heat exchanger will be opened for heating.

[0058] However, in actual control, although the humidity value (65%) is higher than the set value (60%), the moisture content (10.2g / kg) is lower than the set value (11.3g / kg), indicating that the moisture in the air is already low enough and no further dehumidification is required. However, according to the existing control logic, the air conditioning system will operate the surface cooling heat exchanger and the heating heat exchanger, which will increase the energy consumption of the air conditioning system during operation.

[0059] Regarding the situation where the indoor temperature is abnormal during the operation of the air conditioning system: Assume that the indoor set temperature is 24°C and the humidity is 60% (humidity content is 11.3g / kg). If the outdoor air is dry and hot, the return air main temperature is 26°C and the humidity is 60% (humidity content is 11.7g / kg). According to the existing control logic, since the humidity of the return air main has reached the set value, the valves of the surface cooling heat exchanger and the heating heat exchanger will be closed. However, since the air in the clean room continues to generate heat and the outdoor air temperature is high, the indoor temperature will further increase, resulting in abnormal indoor temperature.

[0060] In response to the above problems, the present application provides an air conditioning control method. By obtaining the target temperature and target humidity set by the user, the corresponding dew point temperature is first calculated; then, according to the comparison between the calculated dew point temperature and the outlet temperature of the surface cooling section, the opening of the surface cooling section valve is dynamically adjusted; finally, according to the comparison between the target temperature and the return air temperature, the opening of the heating section valve is dynamically adjusted. Based on the dew point temperature and the return air temperature, this method dynamically adjusts the valves of the surface cooling section and the heating section respectively, avoiding overcooling and ensuring the stability of temperature and humidity control, thereby reducing the operating energy consumption of the air conditioning system and meeting the high requirements of the production process for constant temperature and humidity.

[0061] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0062] Figure 1 The process of the air conditioning control method provided in this embodiment Figure 1 The air conditioner consists of a cooling section and a heating section. The return air and fresh air of the air conditioner are mixed and then pass through the cooling section and the heating section. Figure 1 As shown, the air conditioning control method provided in this embodiment includes:

[0063] S101: Obtain the target temperature and target humidity set by the user.

[0064] The target temperature is used to indicate the ideal temperature value that needs to be maintained in the clean room set by the user according to the production process or environmental requirements.

[0065] The target humidity is used to indicate the ideal humidity value that needs to be maintained in the clean room set by the user according to the production process or environmental requirements.

[0066] The purpose of obtaining the target temperature and target humidity set by the user in this step is to provide a clear adjustment benchmark for the environmental control of the clean room.

[0067] It can be understood that, first of all, the target temperature is determined by the user based on industry standards, product manufacturing requirements or ergonomic principles, and is intended to ensure that the temperature conditions in the area can meet the established working or storage standards, thereby ensuring product quality, work efficiency or personnel health.

[0068] Secondly, the target humidity is the ideal humidity value set by the user based on industry standards, product characteristics or process requirements. It aims to ensure that the humidity conditions in the clean room can meet the needs of preventing static electricity, controlling microbial growth or maintaining material stability, thereby ensuring the stability of the production process and product quality.

[0069] Therefore, by obtaining the target temperature and target humidity set by the user, the air conditioning system can dynamically adjust the operating parameters according to the actual environmental conditions, thereby ensuring that the temperature and humidity in the workshop are stable within the range required by the user.

[0070] The method for obtaining the target temperature and target humidity set by the user in this step may be, for example, that the user directly inputs the target temperature and target humidity values ​​on the touch screen or control panel of the air conditioning system, or that the user connects to the air conditioning system through a mobile phone application to remotely input or adjust the set values ​​of the target temperature and target humidity. This application does not impose any special restrictions on this.

[0071] For example, if the target temperature is 24 degrees Celsius and the target humidity is 50%, it means that in order for the clean workshop to meet the production process or environmental requirements, the user needs to maintain a temperature of 24 degrees Celsius and a humidity of 50%.

[0072] S102: Determine the corresponding dew point temperature according to the target temperature and the target humidity.

[0073] The purpose of determining the corresponding dew point temperature according to the target temperature and the target humidity in this step is to clarify the humidity saturation point of the air under the target temperature and humidity conditions.

[0074] It can be understood that the dew point temperature is the temperature corresponding to when the air reaches a saturated state, that is, the temperature when the water vapor in the air begins to condense into liquid water.

[0075] Since the target temperature and target humidity jointly determine the water vapor content in the air and its state changes, determining the corresponding dew point temperature through the target temperature and target humidity can provide the key humidity control parameters for the air-conditioning system, thereby helping the air-conditioning system to determine the humidity saturation point of the air under the target temperature and humidity conditions.

[0076] S103: Control the valve opening of the surface cooling section according to the dew point temperature and the outlet temperature of the surface cooling section.

[0077] Among them, the surface cooling section is a key component in the air-conditioning system for cooling the air. It is usually composed of a cooling coil and a refrigerant circulation system, which reduces the air temperature through heat exchange between the refrigerant and the air.

[0078] The outlet temperature of the cooling section refers to the actual temperature of the air after it is cooled by the cooling section. For example, if the outlet temperature of the cooling section is 15 degrees Celsius, it means that the actual temperature of the air after it is cooled by the cooling section is 15 degrees Celsius.

[0079] The valve of the surface cooling section is a regulating device for controlling the flow of refrigerant. By changing the valve opening, the flow of refrigerant can be adjusted, thereby controlling the cooling capacity of the surface cooling section.

[0080] This step controls the valve opening of the surface cooling section according to the dew point temperature and the outlet temperature of the surface cooling section to ensure that the air can reach the target humidity condition during the cooling process.

[0081] It can be understood that the dew point temperature is used to characterize the humidity saturation point of the air, while the outlet temperature of the surface cooling section reflects the actual temperature of the air after cooling.

[0082] Therefore, by comparing the dew point temperature and the outlet temperature of the surface cooling section, the air conditioning system can determine whether further cooling is needed to dehumidify or stop cooling to avoid excessive dehumidification, thereby dynamically adjusting the valve opening, optimizing energy use and maintaining stable humidity in the clean room.

[0083] S104: Control the valve opening of the heating section according to the target temperature and the return air temperature.

[0084] Among them, the heating section is a key component in the air-conditioning system for heating the air. It is usually composed of a heating coil or an electric heater, which increases the air temperature through heat exchange or electric heat conversion.

[0085] The return air temperature refers to the temperature of the air returned from the clean room. For example, if the return air temperature is 25 degrees Celsius, it means that the actual temperature in the clean room is 25 degrees Celsius.

[0086] The valve in the heating section is a regulating device for controlling the flow of heat medium. By changing the valve opening, the flow of heat medium can be adjusted, thereby controlling the heating capacity of the heating section.

[0087] This step controls the valve opening of the heating section according to the target temperature and the return air temperature in order to ensure that the temperature in the clean room can quickly and stably reach the target value set by the user.

[0088] It can be understood that the return air temperature is used to represent the actual temperature in the clean room, while the target temperature is used to indicate the ideal temperature value set by the user.

[0089] Therefore, by comparing the return air temperature with the target temperature, the air conditioning system can determine whether heating is needed or stopped, thereby dynamically adjusting the opening of the heating section valve to avoid overheating or underheating, optimize energy use and maintain temperature stability.

[0090] The return air temperature may be acquired in this step by, for example, collecting the temperature through a return air temperature sensor installed in the return air duct.

[0091] The air conditioning control method provided in this embodiment first obtains the target temperature and target humidity set by the user. Then, based on these set values, the corresponding dew point temperature is calculated. Then, based on the difference between the calculated dew point temperature and the outlet temperature of the surface cooling section, the opening of the surface cooling section valve is intelligently adjusted to control the cooling effect and humidity. At the same time, based on the comparison between the target temperature and the actual return air temperature, the valve opening of the heating section is adjusted to ensure that the temperature in the workshop reaches the set value. This method not only ensures the stability of the environmental conditions in the clean workshop, but also effectively solves the problem of high energy consumption of the air-conditioning unit in a high-demand environment by controlling the valves of the surface cooling section and the heating section, thereby providing strong support for energy saving and consumption reduction in clean workshops.

[0092] Figure 2 The process of the air conditioning control method provided in this embodiment Figure 2 .like Figure 2 This embodiment is Figure 1 Based on the embodiment, the implementation process of air conditioning control is described in detail. The air conditioning control method provided in this embodiment includes:

[0093] S201: Obtain the target temperature and target humidity set by the user.

[0094] The explanation of step S201 is similar to that of the above step S101 and will not be repeated here.

[0095] S202: Multiply the target temperature by the first coefficient and then add the second coefficient to obtain a first value.

[0096] The first coefficient may be, for example, 0.0017, and the second coefficient may be, for example, 0.198.

[0097] The purpose of this step is to generate an intermediate value by calculating the target temperature and the preset first coefficient and second coefficient, so as to provide basic data for the subsequent calculation of the dew point temperature.

[0098] It can be understood that by multiplying the target temperature by the first coefficient and adding the second coefficient, the air conditioning system generates an adjusted first value. This value not only takes into account the direct impact of the target temperature, but also combines the preset system parameters to provide more accurate input data for the subsequent calculation of the dew point temperature, thereby supporting the air conditioning system to achieve more efficient temperature and humidity control.

[0099] For example, if the first coefficient is 0.0017, the second coefficient is 0.1980, and the target temperature is 24 degrees Celsius, then based on the above information, the air conditioning system can determine that the first value is 0.2388.

[0100] S203: Multiply the first value by the target humidity, and then add the target temperature multiplied by the third coefficient to obtain a second value.

[0101] The third coefficient may be, for example, 0.84.

[0102] The purpose of this step is to integrate the effects of target humidity and target temperature.

[0103] It can be understood that by multiplying the first value including the target temperature by the target humidity and adding the product of the target temperature and the third coefficient, the system generates a second value. This value not only takes into account the direct impact of the target humidity, but also combines the further adjustment of the target temperature, providing more comprehensive input data for the subsequent calculation of the dew point temperature, thereby supporting the air conditioning system to achieve more efficient temperature and humidity control.

[0104] For example, if the third coefficient is 0.84, the target humidity is 60%, the target temperature is 24 degrees Celsius, and the first value is 0.2388, then based on the above information, the air conditioning system can determine that the second value is 20.30328.

[0105] S204: Subtract the fourth coefficient from the second value to obtain the dew point temperature.

[0106] The fourth coefficient may be, for example, 19.2.

[0107] The purpose of this step is to generate a more accurate dew point temperature based on comprehensive consideration of the target temperature and target humidity.

[0108] It is understandable that the dew point temperature reflects the humidity saturation point of the air in the clean room under the target temperature and humidity conditions. This temperature value not only takes into account the influence of the target temperature, but also combines the effect of the target humidity. It is an important reference for the air conditioning system to determine whether dehumidification or heating is required.

[0109] Therefore, by calculating the dew point temperature, the system can more accurately control the humidity state of the air, thereby ensuring that the environmental parameters in the clean room always meet the requirements of the production process.

[0110] For example, if the fourth coefficient is 19.2 and the second value is 20.30328, then based on the above information, it can be determined that the dew point temperature is 1.10328.

[0111] S205: When the outlet temperature of the surface cooling section is greater than the dew point temperature, increase the valve opening of the surface cooling section.

[0112] The purpose of judging whether the outlet temperature of the surface cooling section is greater than the dew point temperature is to determine whether the air needs to be further cooled to reduce its humidity.

[0113] If it is determined that the outlet temperature of the surface cooling section is greater than the dew point temperature, it indicates that the air needs to be further cooled to reduce its humidity. At this time, the valve opening of the surface cooling section needs to be increased.

[0114] It can be understood that the outlet temperature of the surface cooling section is used to characterize the actual temperature of the air after being cooled by the surface cooling section, reflecting the current cooling effect. The dew point temperature reflects the humidity saturation point of the air under the target temperature and humidity conditions, that is, the temperature when the water vapor in the air begins to condense into liquid water.

[0115] Therefore, when it is determined that the outlet temperature of the surface cooling section is higher than the dew point temperature, it means that the water vapor in the air in the clean room has not yet reached saturation, the air is not cooled enough, and further cooling is still required to condense excess water. At this time, by increasing the opening of the surface cooling section valve, the air conditioning system can increase the refrigerant flow and improve the cooling efficiency.

[0116] In this step, the opening of the surface cooling section valve can be increased by, for example, a preset percentage, such as 20%, based on the current opening, or a preset number of steps, such as 300 steps, based on the current opening. This application does not impose any special restrictions on this.

[0117] For example, assuming that the current opening of the surface cooling section valve is 50%, the surface cooling section outlet temperature is 2.120, and the dew point temperature is 1.10328. Based on the above information, it can be determined that the surface cooling section outlet temperature is higher than the dew point temperature. At this time, the system will control the surface cooling section valve to increase the current opening of 50% by 20%, that is, adjust the valve opening to 70%, in order to increase the refrigerant flow and enhance the cooling effect.

[0118] S206: When the outlet temperature of the surface cooling section is lower than the dew point temperature, the valve opening of the surface cooling section is reduced.

[0119] The purpose of judging whether the outlet temperature of the surface cooling section is less than the dew point temperature is to determine whether the air has been overcooled.

[0120] If it is determined that the outlet temperature of the surface cooling section is lower than the dew point temperature, it indicates that the air has been overcooled. At this time, the valve opening of the surface cooling section can be reduced.

[0121] It can be understood that the surface cooling section outlet temperature is used to characterize the actual temperature of the air after being cooled by the surface cooling section, reflecting the current cooling effect. The dew point temperature reflects the humidity saturation point of the air under the target temperature and humidity conditions.

[0122] Therefore, when it is determined that the outlet temperature of the surface cooling section is lower than the dew point temperature, it means that the air has been overcooled and there may be a risk of over-dehumidification. At this time, by reducing the opening of the surface cooling section valve, the air conditioning system can reduce the refrigerant flow rate and reduce the cooling effect, thereby avoiding overcooling and energy waste.

[0123] In this step, the opening of the surface cooling section valve can be reduced by, for example, a preset percentage, such as 30%, based on the current opening, or by a preset number of steps, such as 100 steps, based on the current opening. This application does not impose any special restrictions on this.

[0124] For example, assuming that the current opening of the surface cooling section valve is 60%, the surface cooling section outlet temperature is 0.9685, and the dew point temperature is 1.10328. Based on the above information, it can be determined that the surface cooling section outlet temperature is lower than the dew point temperature. Therefore, the system will control the surface cooling section valve to reduce the current opening of 60% by 10%, that is, adjust the valve opening to 50%, to reduce the refrigerant flow.

[0125] Optionally, the present application provides a possible implementation method for the case where the outlet temperature of the surface cooling section is equal to the dew point temperature, including: controlling the valve opening of the surface cooling section to remain unchanged.

[0126] The purpose of this step is to maintain the current cooling effect and humidity status.

[0127] It can be understood that when the outlet temperature of the surface cooling section is determined to be equal to the dew point temperature, it means that the water vapor in the air has just reached the saturation state, and there is neither overcooling nor undercooling. Therefore, keeping the valve opening unchanged can maintain the current cooling effect and avoid unnecessary energy waste or humidity fluctuations.

[0128] S207: When the return air temperature is lower than the target temperature, increase the valve opening of the heating section.

[0129] The purpose of judging whether the return air temperature is lower than the target temperature is to determine whether the air needs to be further heated to increase its temperature.

[0130] If it is determined that the return air temperature is lower than the target temperature, it indicates that the air needs to be further heated to increase its temperature. At this time, the valve opening of the heating section can be increased.

[0131] It is understandable that the return air temperature reflects the actual temperature of the air returned from the clean room, while the target temperature is the ideal temperature value set by the user. Therefore, when it is determined that the return air temperature is lower than the target temperature, it means that the actual temperature in the clean room has not reached the set value and further heating is still required to meet the requirements of production process or personnel comfort.

[0132] At this time, by increasing the opening of the heating section valve, the air conditioning system can increase the heat medium flow rate, thereby improving the heating effect and ensuring that the temperature in the workshop reaches the target value quickly and stably.

[0133] In this step, the opening of the heating section valve can be increased by, for example, a preset percentage, such as 10%, based on the current opening, or by a preset number of steps, such as 200 steps, based on the current opening. This application does not impose any special restrictions on this.

[0134] For example, suppose the current opening of the heating section valve is 60%, the return air temperature is 22 degrees Celsius, and the target temperature is 26 degrees Celsius. Based on the above information, it can be determined that the return air temperature is lower than the target temperature. At this time, the system will control the heating section valve to increase the current opening of 60% by 10%, that is, adjust the valve opening to 70%, in order to increase the heat medium flow and improve the heating effect.

[0135] S208: When the return air temperature is greater than the target temperature, reduce the valve opening of the heating section.

[0136] The purpose of judging whether the return air temperature is greater than the target temperature is to determine whether heating needs to be reduced to avoid overheating.

[0137] If it is determined that the return air temperature is greater than the target temperature, it means that the heating needs to be reduced to avoid overheating. At this time, the valve opening of the heating section can be reduced.

[0138] It is understandable that when the return air temperature is greater than the target temperature, it means that the actual temperature in the clean room has exceeded the set value. Continuing heating not only wastes energy, but may also cause the temperature to be too high, affecting the production process or the comfort of personnel. Therefore, by reducing the valve opening, the system can reduce the heat medium flow rate and reduce the heating effect, thereby maintaining temperature stability.

[0139] In this step, the opening of the heating section valve can be reduced by, for example, a preset percentage, such as 5%, based on the current opening, or by a preset number of steps, such as 200 steps, based on the current opening. This application does not impose any special restrictions on this.

[0140] For example, suppose the current opening of the heating section valve is 80%, the return air temperature is 27 degrees Celsius, and the target temperature is 26 degrees Celsius. Based on the above information, it can be determined that the return air temperature is greater than the target temperature. At this time, the system will control the heating section valve to reduce the current opening of 80% by 20%, that is, adjust the valve opening to 60%.

[0141] Optionally, the present application provides a possible implementation method for the case where the return air temperature is equal to the target temperature, including: controlling the valve opening of the heating section to remain unchanged.

[0142] The purpose of this step is to maintain the current heating effect and temperature status.

[0143] It can be understood that when the return air temperature is determined to be equal to the target temperature, it means that the actual temperature in the workshop is neither too high nor too low, and no further heating or reduced heating is required. Therefore, keeping the valve opening unchanged can maintain the current heating effect and avoid unnecessary energy waste or temperature fluctuations.

[0144] The air conditioning control method provided in the present application first obtains the target temperature and target humidity set by the user; then, the corresponding dew point temperature is calculated by combining the target temperature and target humidity with preset coefficients (first coefficient, second coefficient, third coefficient and fourth coefficient); then, according to the comparison result of the outlet temperature of the surface cooling section and the dew point temperature, the opening of the valve of the surface cooling section is dynamically adjusted: if the outlet temperature of the surface cooling section is greater than the dew point temperature, the valve opening is increased to enhance cooling; if it is less than the dew point temperature, the valve opening is reduced to avoid overcooling; finally, according to the comparison result of the return air temperature and the target temperature, the opening of the valve of the heating section is dynamically adjusted: if the return air temperature is less than the target temperature, the valve opening is increased to enhance heating; if it is greater than the target temperature, the valve opening is reduced to avoid overheating.

[0145] By comparing the outlet temperature of the surface cooling section with the dew point temperature, and the return air temperature with the target temperature, this method can dynamically adjust the valve opening of the surface cooling section and the heating section to avoid excessive cooling or heating, effectively solving the problem of high energy consumption of the air-conditioning unit, and ensuring that the temperature and humidity conditions in the clean room are always stable within the set range, thereby meeting the high requirements of the production process for constant temperature and humidity.
