[0055] Detailed implementation manners

[0056] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part rather than all of the embodiments of the present application.

[0057] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0058] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. To enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part rather than all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0059] The present invention provides a humidification system. Refer to Figure 1 , Figure 1 which is a schematic structural diagram of the humidification system of the present invention; the humidification system 0 includes an air duct, a wet film humidifier 05 and a heating module 04; the air duct includes an air inlet 02 and an air outlet 071, the wet film humidifier 05 and the heating module 04 are arranged in the air duct, and the heating module 04 is arranged between the air inlet 02 of the air duct and the wet film humidifier 05.

[0060] The air duct is the passage for air circulation in the humidification system; the air duct includes an air inlet 02 and an air outlet 071. The outside air enters the air duct from the air inlet 02, and after being humidified in the air duct, it is output from the air outlet 071 to the humidification position. For example, in the scenario of humidifying Room 1, the air inlet 02 of the air duct can be connected to the outside, and the air outlet 071 is connected to Room 1. The outside air enters the air duct through the air inlet 02 for humidification and is output from the air outlet 071 to Room 1 to humidify Room 1.

[0061] The wet film humidifier 05 realizes isenthalpic humidification by using the natural evaporation process. The wet film humidifier 05 is arranged in the air duct. During the process of air flowing from the air inlet 02 to the air outlet 071, it will pass through the wet film humidifier 05, and the wet film humidifier 05 humidifies the air flowing through it. In a high-temperature environment, air can carry more water vapor. Therefore, the water on the surface of the wet film humidifier 05 evaporates faster, and the humidification efficiency of the air is higher. In a low-temperature environment, the ability of air to carry water vapor weakens, the water on the surface of the wet film humidifier 05 evaporates slower, and the humidification efficiency is lower.

[0062] The heating module 04 is used to heat the air; the heating module 04 is arranged between the air inlet 02 and the wet film humidifier 05, so that the air will pass through the heating module 04 before reaching the wet film humidifier 05. Therefore, the air is heated by the heating module 04, which can increase the temperature of the air reaching the wet film humidifier 05, and then improve the humidification efficiency of the wet film humidifier 05.

[0063] The specific type of the heating module 04 can be set according to actual needs, such as an electric heater.

[0064] In this embodiment, by arranging the wet film humidifier 05 between the air inlet 02 and the air outlet 071, the air can be humidified by passing through the wet film humidifier 05 during the process of being transmitted from the air inlet 02 to the air outlet 071. And by arranging the heating module 04 between the air inlet 02 and the wet film humidifier 05, the air can be heated by the heating module 04 before reaching the wet film humidifier 05, so that the temperature of the air reaching the wet film humidifier 05 can be increased, and the humidification efficiency of the wet film humidifier 05 can be improved. Therefore, even in a low-temperature environment, the humidification efficiency of the wet film humidifier 05 can be ensured by the heating module 04.

[0065] Further, the air duct further includes a first mixing chamber 03 and a return air duct 01. The first mixing chamber 03 is arranged between the air inlet 02 of the air duct and the heating module 04, and the first mixing chamber 03 is also connected to the first air outlet 012 of the return air duct 01.

[0066] The air return opening 011 of the air return duct 01 is connected to the room 1. In this embodiment, the air entering the air duct includes fresh air entering from the external environment and the air return recovered from the room 1; the fresh air enters the first mixing chamber 03 from the air inlet 02, and the air return enters the air return duct 01 from the air return opening 011 of the air return duct 01 and enters the first mixing chamber 03 through the first air outlet 012 of the air return duct 01; the fresh air and the air return are mixed in the first mixing chamber 03.

[0067] By setting the air return duct 01 to input the air return, the demand for the fresh air volume can be reduced, thereby reducing energy consumption; at the same time, the temperature and humidity state of the room 1 can also be stabilized. The specific mixing ratio of the fresh air and the air return can be set based on actual needs. For example, the fresh air to air return ratio can be set to 20%, that is, the fresh air volume accounts for 80% and the air return volume accounts for 20%.

[0068] Further, the humidification system further includes a fresh air filtering device 031; the fresh air filtering device 031 is arranged between the first mixing chamber 03 and the heating module 04.

[0069] By arranging the fresh air filtering device 031 between the first mixing chamber 03 and the heating module 04, the mixed air will pass through the fresh air filtering device 031 before entering the heating module 04. Therefore, the impurities entering the humidification system can be filtered, thus preventing external impurities from entering the system and affecting the normal operation of the system.

[0070] Further, the air duct further includes a second mixing chamber 07, the second mixing chamber 07 is arranged between the wet film humidifier 05 and the air outlet 071 of the air duct, and the second mixing chamber 07 is also communicated with the second air outlet 013 of the air return duct 01.

[0071] In this embodiment, the air output to the room includes the air humidified by the wet film humidifier 05 and the air return recovered from the room; the humidified air is output to the second mixing chamber 07 after being humidified by the wet film humidifier 05, and the air return enters the second mixing chamber 07 through the second air outlet 013 of the air return duct 01; the humidified air and the air return are mixed for a second time in the second mixing chamber 07.

[0072] By setting the air return duct 01 to input the air return, the demand for the air intake volume can be further reduced, thereby reducing energy consumption; the specific air volume value of the second air return can be set based on the actual operation state of the system.

[0073] When setting each air volume, it can be determined based on the actual air volume demand and settings; for example, first determine the real-time heat and humidity load in the room and the air return state point N and the target supply air state point O.

[0074] See Figure 2, the indoor real-time heat and humidity load can be determined by controlling the temperature difference and the humidity difference. The controlled temperature difference is the difference between the target temperature and the current indoor temperature, and the controlled humidity difference is the difference between the target humidity and the current indoor humidity.

[0075] The return air state point N indicates the temperature and relative humidity of the return air, which can be specifically detected by setting a temperature sensor and a humidity sensor 055 at the return air inlet 011 of the return air duct 01.

[0076] The target supply air state point O indicates the desired supply air temperature and supply air humidity; the target supply air state point O can be determined by the indoor real-time heat and humidity load and the maximum supply air temperature difference; first, determine the indoor real-time heat and humidity load line on the enthalpy-humidity diagram, and take the intersection of the indoor real-time heat and humidity load line and the maximum supply air temperature difference line as the target supply air state point O; the specific temperature difference value of the maximum supply air temperature difference line can be set based on actual needs, such as 3°C.

[0077] The return air state point N indicates the real-time state of Room 1, the target supply air state point O indicates the desired supply air state, and the indoor real-time heat and humidity load indicates the control requirement. Therefore, the required supply air volume can be determined through the return air state point N, the target supply air state point O, and the indoor real-time heat and humidity load.

[0078] The air volume in the air duct can be considered conserved, that is, the incoming air volume is equal to the supply air volume. The air duct contains three incoming air points, namely fresh air, primary return air, and secondary return air. Fresh air is the air entering through the air inlet 02, primary return air is the return air output from the first air outlet 012 of the return air duct 01, and secondary return air is the return air output from the second air outlet 013 of the return air duct 01. Therefore, it can be obtained that:

[0079] G O = G W + G N1 + G N2

[0080] Among them, G o is the supply air volume, G w is the fresh air volume, G N1 is the primary return air volume, G N2 is the secondary return air volume.

[0081] And from the heat formula, it can be obtained that:

[0082] (G N1 + G W ) × NO = G N2 × LO

[0083] Among them, N is the return air state point, O is the target supply air state point, and L is the initial state point of the secondary return air;

[0084] The initial state point L of the secondary return air is the intersection point of the straight line connecting the return air state point N and the target supply air state point O on the psychrometric chart and the target relative humidity line. The target relative humidity line can be selected based on actual needs, such as the 95% relative humidity line.

[0085] Therefore, when the supply air volume, the return air state point N, and the target supply air state point O are known, the initial state point L of the secondary return air can be calculated.

[0086] After the initial state point L of the secondary return air is determined, the target supply air volume, that is, the sum of the fresh air volume and the primary return air volume, can be obtained; since the ratio of the fresh air volume to the primary return air volume is known, such as the 20% fresh-to-return air ratio mentioned above, that is:

[0087] G N1 =4G W

[0088] When the target supply air volume is known, the fresh air volume and the primary return air volume can be obtained.

[0089] Furthermore, the humidification system further includes a supply air filtration device 072; the supply air filtration device 072 is arranged between the wet film humidifier 05 and the second mixing chamber 07.

[0090] If the supply air filtration device 072 is arranged between the wet film humidifier 05 and the second mixing chamber 07, the humidified and mixed air will pass through the supply air filtration device 072 before being output to the room 1. Therefore, the impurities entering the humidification system can be filtered, thus preventing system impurities from entering the room 1 and affecting the air quality of the room 1.

[0091] Furthermore, the humidification system further includes a cooling coil 06; the cooling coil 06 is arranged between the wet film humidifier 05 and the air supply outlet 071 of the air duct.

[0092] It can be understood that the heating operation of the heating module 04 will cause the air temperature to rise; and when the humidification device is in the refrigeration mode, it is necessary to prevent the supply air temperature from being too high and affecting the indoor temperature; therefore, in this embodiment, the cooling coil 06 is arranged between the wet film humidifier 05 and the air supply outlet 071; the air entering the air duct is first heated by the heating module 04 and then humidified in the wet film humidifier 05, so as to improve the humidification efficiency. After the humidification is completed, it is cooled by the cooling coil 06, so as to reduce the supply air temperature and prevent affecting the indoor refrigeration effect.

[0093] When the cooling coil 06 and the supply air filtration device 072 are both provided, the supply air filtration device 072 can be arranged between the cooling coil 06 and the air supply outlet 071, so as to achieve a better filtration effect.

[0094] The specific temperature of the cooling coil 06 can be set based on actual needs. For example, after the initial state point L of the secondary return air is determined, the temperature corresponding to the initial state point L of the secondary return air is the desired temperature before mixing with the secondary return air. Therefore, setting the coil temperature of the cooling coil 06 to the temperature corresponding to the initial state point L of the secondary return air can make the temperature of the air after mixing with the secondary return air reach the temperature corresponding to the target supply air state point O. Specifically, the evaporation temperature of the evaporation side corresponding to the cooling coil 06 can be set to the dew point temperature corresponding to the initial state point L of the secondary return air; since the air needs to be mixed with the secondary return air after being cooled by the cooling coil 06, in order to further ensure that the temperature corresponding to the target supply air state point O can be reached, the coil temperature of the cooling coil 06 can be set to be lower than the temperature corresponding to the initial state point L of the secondary return air.

[0095] Furthermore, the humidifying system further includes a first temperature sensor 041, a second temperature sensor 051, and a humidity sensor 055; wherein:

[0096] The first temperature sensor 041 is disposed on the side of the heating module 04 close to the wet film humidifier 05, the second temperature sensor 051 is disposed on the wet film humidifier 05, and the humidity sensor 055 is disposed on the side of the wet film humidifier 05 close to the air outlet 071.

[0097] In order to achieve more precise humidification and temperature control, it is necessary to detect the operating state of the humidifying system; specifically, in this embodiment, a first temperature sensor 041 is disposed on the side of the heating module 04 close to the wet film humidifier 05 to detect the temperature of the air heated by the heating module 04 to obtain the current heating temperature; a second temperature sensor 051 is disposed on the wet film humidifier 05 to detect the surface temperature of the wet film humidifier 05; a humidity sensor 055 is disposed on the side of the wet film humidifier 05 close to the air outlet 071 to detect the moisture content of the air humidified by the wet film humidifier 05 to obtain the output moisture content.

[0098] It can be understood that as the current heating temperature increases, the temperature of the air entering the wet film humidifier 05 rises, and the humidifying effect of the wet film humidifier 05 is enhanced, with the output moisture content increasing; similarly, as the surface temperature of the wet film humidifier 05 itself increases, the humidifying effect of the wet film humidifier 05 is enhanced, and the output moisture content increases; that is, there is an interaction relationship among the current heating temperature, the output moisture content, and the surface temperature; in this embodiment, by detecting the current heating temperature, the output moisture content, and the surface temperature, it is possible to determine the actual heating requirement based on these parameters, thereby realizing the control of the heating module 04 and the wet film humidifier 05; specifically, when the output moisture content does not meet the output humidity requirement, the output moisture content can be increased by improving the heating effect of the heating module 04 to increase the current heating temperature, or by increasing the surface temperature of the wet film humidifier 05; however, since the increase in the surface temperature of the wet film humidifier 05 will affect the overall operation of the system, is relatively complex in control, and will also increase the power consumption significantly, therefore, heating can be preferentially carried out through the heating module 04. When the heating effect of the heating module 04 cannot meet the requirement of improving the humidifying efficiency, the surface temperature of the wet film humidifier 05 can be increased to further increase the output moisture content.

[0099] Further, the humidifying system further includes a third temperature sensor 032; wherein:

[0100] The third temperature sensor 032 is disposed on one side of the first mixing chamber 03 close to the heating module 04.

[0101] In this embodiment, the third temperature sensor 032 is disposed on one side of the first mixing chamber 03 close to the heating module 04, enabling the detection of the mixed air state point C after the fresh air and the return air are mixed; through the mixed air state point C, the heating state point C1 after isohumidifying heating by the heating module 04 and the humidifying state point C2 after isenthalpic humidifying by the wet film humidifier 05 can be determined.

[0102] It should be noted that based on the actual detection needs, corresponding sensors can also be set to detect the parameters to be detected, such as temperature sensors and humidity sensors 055 are respectively disposed at the air return opening 011 of the air return duct 01; temperature sensors and humidity sensors 055 are respectively disposed in the outdoor environment.

[0103] The present invention provides a humidifying method, referring to Figure 1 , Figure 1 which is a schematic flowchart of the first embodiment of the humidifying method of the present invention, and the method includes the steps:

[0104] Step S10, obtaining the humidifying state of the wet film humidifier;

[0105] The humidification state is used to indicate the humidification condition of the wet film humidifier; for example, the humidification state can specifically indicate the moisture content and temperature of the air after humidification by the wet film humidifier.

[0106] Step S20, determine the target control command corresponding to the humidification state;

[0107] The target control command indicates the parameters of the heating setting of the heating module.

[0108] The setting of the heating module is to increase the temperature of the air reaching the wet film humidifier, thereby improving the humidification efficiency of the wet film humidifier; therefore, when the humidification state indicates that the humidification efficiency of the wet film humidifier is low, heating needs to be carried out through the heating module. The lower the humidification efficiency, correspondingly, the higher the heating degree of the heating module indicated by the target control command, so as to achieve a greater improvement in the humidification efficiency.

[0109] Step S30, control the heating module to heat the air output to the wet film humidifier according to the target control command.

[0110] After the target control command is determined, the heating module is heated according to the target control command to increase the temperature of the air output to the wet film humidifier, so as to improve the humidification efficiency.

[0111] In this embodiment, by setting a wet film humidifier between the air inlet and the air outlet, the air can be humidified by the wet film humidifier during the process of being transmitted from the air inlet to the air outlet, and a heating module is set between the air inlet and the wet film humidifier, so that the air can be heated by the heating module before reaching the wet film humidifier, thereby increasing the temperature of the air reaching the wet film humidifier and improving the humidification efficiency of the wet film humidifier. Therefore, even in a low-temperature environment, the humidification efficiency of the wet film humidifier can be ensured through the heating module.

[0112] Further, in the second embodiment of the humidification method of the present invention proposed based on the first embodiment of the present invention, the humidification state includes the output humidity, and the step S20 includes the steps:

[0113] Step S21, obtain the target moisture content, and judge whether the output moisture content reaches the target moisture content;

[0114] Step S22, if the output moisture content does not reach the target moisture content, determine that the target control command is to increase the heating temperature.

[0115] The target moisture content is the moisture content required for the air currently output by the humidification system.

[0116] The output moisture content is the moisture content of the air actually humidified by the wet film humidifier.

[0117] When the output moisture content does not reach the target moisture content, it is considered that the humidification efficiency of the wet film humidifier is low and does not meet the current humidification requirements. It is necessary to improve the humidification efficiency of the wet film humidifier. Therefore, it is necessary to increase the temperature of the air reaching the wet film humidifier. Therefore, the target control instruction is set to increase the heating temperature to improve the heating degree of the air by the heating module; so that the control of the heating module can be accurately realized based on the specific humidification efficiency; the form of the specific target control instruction can be set according to actual needs; for example, the heating temperature in the target control instruction can indicate the temperature of the air after being heated by the heating module, such as making the temperature of the air after being heated by the heating module increase by 1°C based on the current heating temperature, where the current heating temperature is the current temperature of the air after being heated by the heating module; another example is that the heating temperature in the target control instruction can indicate the setting parameter of the heating module, such as increasing the power by one step based on the current heating power of the heating module to improve the heating effect of the heating module, and the specific step can be set according to actual needs.

[0118] To avoid large fluctuations in the system state and affect the stability of the system, when the target control instruction indicates an increase in the heating temperature, a fixed heating step can be set, such as 1°C, and the heating temperature is increased by one heating step each time.

[0119] Step S23, if the output moisture content reaches the target moisture content, obtain the initial state point of the secondary return air;

[0120] Step S24, determine the dew point temperature corresponding to the initial state point of the secondary return air as the target temperature;

[0121] Step S25, set the coil temperature corresponding to the cooling coil to the target temperature.

[0122] If the output moisture content reaches the target moisture content, it is considered that the humidification efficiency of the wet film humidifier meets the current humidification requirements. Therefore, there is no need to increase the heating temperature anymore; in this case, the adjustment of the air before the cooling coil has been completed, that is, the heating and humidification operations have been executed. At this time, cooling is required through the cooling coil to be able to reduce the temperature of the supply air and avoid affecting the indoor cooling effect.

[0123] After the initial state point L of the secondary return air is determined, the temperature corresponding to the initial state point L of the secondary return air is the temperature expected before mixing with the secondary return air. Therefore, by setting the coil temperature of the cooling coil to the temperature corresponding to the initial state point L of the secondary return air, the temperature of the air after mixing with the secondary return air can reach the temperature corresponding to the target supply air state point O. Specifically, the evaporation temperature of the evaporation side corresponding to the cooling coil can be set to the dew point temperature corresponding to the initial state point L of the secondary return air; since the air needs to be mixed with the secondary return air after being cooled by the cooling coil, in order to further ensure that the temperature corresponding to the target supply air state point O can be reached, the coil temperature of the cooling coil can be set to be lower than the temperature corresponding to the initial state point L of the secondary return air.

[0124] Further, the step S22 includes the steps of:

[0125] Step S221, obtaining the current heating temperature of the heating module;

[0126] Step S222, judging whether the current heating temperature reaches the maximum temperature threshold;

[0127] Step S223, if the current heating temperature reaches the maximum temperature threshold, controlling the surface temperature of the wet film humidifier to increase, and determining the target control instruction to maintain the current heating temperature;

[0128] Step S224, if the current heating temperature does not reach the maximum temperature threshold, determining the target control instruction to increase the heating temperature.

[0129] It can be understood that when the current heating temperature of the air reaching the wet film humidifier is greater than the surface temperature of the wet film humidifier, the growth rate of the humidification efficiency will slow down as the current heating temperature increases, and then the heating benefit will decrease; therefore, after the current heating temperature is heated to a certain extent by the heating module, the air can no longer be further heated by the heating module, but the surface temperature of the wet film humidifier can be increased, so as to achieve a greater improvement in the humidification efficiency; and since the increase in the surface temperature of the wet film humidifier will affect the overall operation of the system, is relatively complex in control, and will also increase the power consumption greatly, therefore, heating is preferentially carried out by the heating module. When the heating effect of the heating module cannot meet the requirement of improving the humidification efficiency, that is, when the maximum temperature threshold is reached, the surface temperature of the wet film humidifier is increased to further increase the output moisture content; while achieving convenience, the humidification efficiency is improved.

[0130] The specific value of the maximum temperature threshold can be set based on actual needs, such as 30 degrees Celsius.

[0131] Similarly, when increasing the surface temperature of the wet film humidifier, in order to avoid large fluctuations in the system state and affect the stability of the system, a fixed heating step size can be set, such as 5 °C, and the heating temperature is increased by one heating step each time.

[0132] Further, the step S21 includes the steps of:

[0133] Step S211, determining the return air state point, where the return air state point includes the return air temperature and the return air humidity;

[0134] Step S212, determining the target supply air state point, where the target supply air state point includes the target supply air temperature and the target supply air humidity;

[0135] Step S213, determining the straight line where the return air state point and the target supply air state point are located, and taking the intersection point of the straight line and the target relative humidity line on the enthalpy-humidity diagram as the initial state point of the secondary return air;

[0136] Step S214, taking the moisture content corresponding to the initial state point of the secondary return air as the target moisture content.

[0137] The return air state point N indicates the temperature and relative humidity of the return air, which can be specifically detected by setting a temperature sensor and a humidity sensor at the return air outlet of the return air duct.

[0138] The target supply air state point O indicates the desired supply air temperature and supply air humidity; the target supply air state point O can be determined by the indoor real-time heat and moisture load and the maximum supply air temperature difference; first, determine the indoor real-time heat and moisture load line on the enthalpy-humidity diagram, and take the intersection point of the indoor real-time heat and moisture load line and the maximum supply air temperature difference line as the target supply air state point O; the specific temperature difference value of the maximum supply air temperature difference line can be set based on actual needs, such as 3 °C.

[0139] The initial state point L of the secondary return air is the intersection point of the straight line where the return air state point N and the target supply air state point O are located on the enthalpy-humidity diagram and the target relative humidity line. The target relative humidity line can be selected based on actual needs, such as the 95% relative humidity line.

[0140] The initial state point L of the secondary return air indicates the air state before mixing with the secondary return air, that is, the air state after humidification by the wet film humidifier. Therefore, taking the moisture content corresponding to the initial state point L of the secondary return air as the target moisture content can ensure that the moisture content of the air after humidification by the wet film humidifier can meet the initial state point L of the secondary return air.

[0141] Further, before the step S10, it includes:

[0142] Obtaining the primary mixing temperature and judging whether the primary mixing temperature reaches the preset initial temperature;

[0143] If the primary mixing temperature does not reach the preset initial temperature, control the heating module to raise the air output to the wet film humidifier to the preset initial temperature;

[0144] If the primary mixing temperature reaches the preset initial temperature, obtain the humidification state of the wet film humidifier.

[0145] The primary mixing temperature is the air temperature output from the first mixing chamber.

[0146] When the primary mixing temperature is too low, the humidification efficiency of the wet film humidifier will also be too low. Therefore, when the humidification system is started, the primary mixing temperature is first detected. When the primary mixing temperature does not reach the preset initial temperature, it is considered that the air needs to be heated. Therefore, after the air is quickly heated to the preset initial temperature by the heating module, the humidification state is obtained and subsequent operations are performed to quickly start the humidification system; when heating the air to the preset initial temperature, in order to avoid large fluctuations in the system state and affect the stability of the system, a fixed heating step size can be set, such as 1 °C, and the heating temperature is increased by one heating step size each time.

[0147] The specific value of the preset initial temperature can be set based on actual needs, such as 15 °C.

[0148] Further, in the third embodiment of the humidification method of the present invention proposed based on the first embodiment of the present invention, the method further includes the steps:

[0149] Step S40, obtain the outdoor ambient temperature;

[0150] Step S50, determine whether the outdoor ambient temperature is greater than the ambient temperature threshold;

[0151] Step S60, if the outdoor ambient temperature is greater than the ambient temperature threshold, determine that the target control instruction is not to perform heating.

[0152] The outdoor ambient temperature can be obtained by setting a temperature sensor outdoors, or can also be obtained through network acquisition and other means.

[0153] When the outdoor ambient temperature is high, the temperature of the fresh air entering the air duct will also be high. In this case, good humidification efficiency can be achieved without heating the incoming air through the heating module. At this time, in order to reduce the energy consumption of the humidification system, the target control instruction is set to not perform heating, that is, the heating module is turned off.

[0154] Specifically, the outdoor ambient temperature is determined to be high by setting an ambient temperature threshold; when the outdoor ambient temperature is greater than the ambient temperature threshold, it is considered that the outdoor ambient temperature is high, and when the outdoor ambient temperature is less than or equal to the ambient temperature threshold, it is considered that the outdoor ambient temperature is not high enough. The specific value of the ambient temperature threshold can be set based on actual needs, such as 35°C.

[0155] Further, in the fourth embodiment of the humidification method of the present invention proposed based on the first embodiment of the present invention, the method further includes the steps of:

[0156] Step S70, determining the target supply air volume;

[0157] Step S80, obtaining the return air state point, the target supply air state point, and the initial state point of the secondary return air, and determining the secondary return air volume according to the target supply air volume, the return air state point, the target supply air state point, and the initial state point of the secondary return air;

[0158] Step S90, subtracting the secondary return air volume from the target supply air volume to obtain the target intake air volume;

[0159] Step S100, obtaining a preset fresh air return air ratio, and determining the fresh air volume and the primary return air volume according to the preset fresh air return air ratio, wherein the sum of the fresh air volume and the primary return air volume is the target intake air volume.

[0160] First, determine the indoor real-time heat and moisture load, the return air state point N, and the target supply air state point O.

[0161] The indoor real-time heat and moisture load can be determined by the control temperature difference and the control humidity difference. The control temperature difference is the difference between the target temperature and the current indoor temperature, and the control humidity difference is the difference between the target humidity and the current indoor humidity.

[0162] The return air state point N indicates the temperature and relative humidity of the return air, and can be specifically detected by setting a temperature sensor and a humidity sensor at the return air outlet of the return air duct.

[0163] The target supply air state point O indicates the desired supply air temperature and supply air humidity; the target supply air state point O can be determined by the indoor real-time heat and moisture load and the maximum supply air temperature difference; first, determine the indoor real-time heat and moisture load line on the psychrometric chart, and take the intersection of the indoor real-time heat and moisture load line and the maximum supply air temperature difference line as the target supply air state point O; the specific temperature difference value of the maximum supply air temperature difference line can be set based on actual needs, such as 3°C.

[0164] The return air state point N indicates the indoor real-time state, the target supply air state point O indicates the desired supply air state, and the indoor real-time heat and moisture load indicates the control requirement. Therefore, the required supply air volume can be determined through the return air state point N, the target supply air state point O, and the indoor real-time heat and moisture load.

[0165] The air volume in the air duct can be considered conserved, that is, the incoming air volume is equal to the supply air volume. The air duct contains three air inlet points, namely fresh air, primary return air, and secondary return air. Fresh air is the air entering through the air inlet, primary return air is the return air output from the first air outlet of the return air duct, and secondary return air is the return air output from the second air outlet of the return air duct. Therefore, it can be obtained that:

[0166] G O = G W + G N1 + G N2

[0167] Among them, G o is the supply air volume, G w is the fresh air volume, G N1 is the primary return air volume, G N2 is the secondary return air volume.

[0168] And from the heat formula, it can be obtained that:

[0169] (G N1 + G W ) × NO = G N2 × LO

[0170] Among them, N is the return air state point, O is the target supply air state point, and L is the initial state point of the secondary return air;

[0171] The initial state point L of the secondary return air is the intersection point of the straight line where the return air state point N and the target supply air state point O are located on the enthalpy-humidity diagram and the target relative humidity line. The target relative humidity line can be selected based on actual needs, such as the 95% relative humidity line.

[0172] Therefore, when the supply air volume, the return air state point N, and the target supply air state point O are known, the initial state point L of the secondary return air can be calculated.

[0173] After the initial state point L of the secondary return air is determined, the target supply air volume can be obtained, that is, the sum of the fresh air volume and the primary return air volume; Since the ratio of the fresh air volume to the primary return air volume is known, such as the 20% fresh return air ratio mentioned above, that is:

[0174] G N1 = 4G W

[0175] When the target supply air volume is known, the fresh air volume and the primary return air volume can be obtained.

[0176] Specifically set each air volume through each state point so that the air volume can meet the wind force requirements of the system.

[0177] The following is based on Figure 3Description of the overall control process of this application:

[0178] 1. Determination of each state point of the system in the refrigeration and humidification mode. First, determine the return air state point N (such as temperature 10°C and relative humidity 85%). Determine the target supply air state point O through the real-time indoor heat and moisture load and the maximum supply air temperature difference (such as 3°C). The intersection of the line connecting points N and O on the psychrometric chart and the 95% relative humidity line is the initial state point L of the secondary return air. On the line connecting the outdoor state point W and the indoor state point N, determine the mixed air state point C after mixing fresh air and return air according to the fresh air return air ratio of 20%. Point C1 is the heating state point after isohumidically heating point C by an electric heater, and point C2 is the humidification state point after isenthalpic humidification of point C1 by a wet film humidifier.

[0179] 2. Determination of the air volume of each part of the system in the refrigeration and humidification mode. First, determine the supply air volume GO through the indoor heat and moisture load, the return air state point N, and the target supply air state point O. Determine the secondary return air volume GN2 through the initial state point L of the secondary return air. According to the fresh air return air ratio of 20%, the fresh air volume GW and the primary return air volume GN1 can be determined respectively.

[0180] 3. Detect and determine the indoor temperature (such as 10°C) and the relative humidity standard value (such as 85%) of the stable return air state point N. When the unit is in the refrigeration mode, set it as a secondary return air system. Fresh air and return air are mixed in the first mixing chamber according to the fresh air return air ratio of 20%. Then, control the air temperature TC1 of the state point C1 after mixing fresh air and return air by an electric heater to 15°C, and set the surface temperature of the wet film humidifier to 20°C.

[0181] Considering reducing the reheating components of the unit, while meeting the fresh air volume, set the return air method in the refrigeration and humidification mode as secondary return air.

[0182] When the outdoor air temperature is higher than 35°C, the temperature after mixing according to the fresh air return air ratio of 20% may be greater than 15°C. At this time, the electric heater is not turned on, and the mixed air is directly sent to the wet film humidifier;

[0183] 4. In the refrigeration and humidification mode, after the heated air is humidified by the wet film humidifier, determine whether its moisture content WC2 is greater than the target moisture content WL of the initial state point L of the secondary return air. If the moisture content is less than the target moisture content, heat the air temperature TC1 of the mixed fresh air and return air to 16°C (increasing in steps of 1°C), continue humidification, and at the same time determine the moisture content until the moisture content of the humidification state point C2 after humidification is greater than the target moisture content, then it is considered that the humidification requirement is met; then use the cooling coil in the refrigeration system to cool C2 to the temperature corresponding to L, and mix to the target supply air state point O by adjusting the air volume of the secondary return air and the air (L) after heating, humidifying, and cooling treatment.

[0184] Point O is the target air supply state point, which is determined by the internal heat and moisture load of Room 1 and the maximum air supply temperature difference (such as 3°C). Point L is determined by the intersection of the line connecting the return air state point (N) and the target air supply state point (O) with the 95% relative humidity line. The evaporation temperature on the evaporation side is controlled to the dew point temperature of L.

[0185] Since after the inlet air temperature is greater than the surface water film temperature of the wet film humidifier, the growth rate of the humidification efficiency slows down as the inlet air temperature increases. Set the maximum value of the air temperature after heating the mixed fresh air and return air by the electric heater (such as 30°C), and the minimum value is the primary mixing temperature TC.

[0186] If the humidification requirement still cannot be met when the mixed fresh air and return air temperature reaches the maximum value of 30°C, then raise the surface temperature of the wet film humidifier to 25°C (increasing in steps of 5°C), and re-regulate on this basis; if the mixed fresh air and return air temperature is the minimum value TC, the humidification requirement can be met without electric heating, saving the energy consumption of the electric heating part.

[0187] 5. Calculate the refrigerating capacity according to the indoor load and meet the indoor temperature requirement through the cooling coil.
