[0030] The present application embodiment provides an air conditioning control system. Figure 1 , which is a structural diagram of an air conditioning control system according to an embodiment of the present application.

[0031] In the embodiment of the present application, the air conditioning control system at least includes: a temperature sensor group (not shown in the figure), a first coil 1, a second coil 2, a fan 3 and a control device (not shown in the figure). Figure 1 Inside the dotted box area.

[0032] The temperature sensor group detects air temperature information corresponding to the external environment and water temperature information corresponding to the internal environment of the air conditioner. The types of air conditioners include but are not limited to water-cooled air conditioners. The external environment of the air conditioner refers to the space environment where the air conditioner is located. For example, the indoor environment where the air conditioner is located. Air temperature information includes but is not limited to: the ambient temperature corresponding to the space environment where the air conditioner is located. The internal environment of the air conditioner refers to the internal environment of the air conditioner. Water temperature information includes but is not limited to: the water flow temperature in the air conditioner.

[0033] The first coil 1 and the second coil 2 are both arranged between the air inlet 4 and the air outlet 5 of the air conditioner; wherein the diameter of the first coil 1 is smaller than the diameter of the second coil 2.

[0034] The control device is respectively connected to the temperature sensor group, the first coil 1, the second coil 2 and the fan 3, and controls the on and off states of the first coil 1 and the second coil 2 and the rotation speed of the fan 3 in a linkage manner according to the air temperature information and the water temperature information detected by the temperature sensor group.

[0035] In an embodiment of the present application, the temperature sensor group includes a plurality of temperature sensors respectively arranged at different positions. The types of temperature sensors include: a temperature sensor for detecting ambient temperature and a temperature sensor for detecting water temperature. The number of temperature sensors for detecting ambient temperature is at least one, which can be arranged in the external environment where the air conditioner is located. The number of temperature sensors for detecting water temperature is four, which are respectively arranged at the water inlet 11 of the first coil 1, the water outlet 12 of the first coil 1, the water inlet 21 of the second coil 2, and the water outlet 22 of the second coil 2.

[0036] In the embodiment of the present application, the first coil 1 and the second coil 2 are both arranged between the air inlet 4 and the air outlet 5 of the air conditioner. After the fan 3 is started, the airflow enters the air duct from the air inlet 4, passes through the first coil 1, then passes through the second coil 2, and then exits the air duct from the air outlet 5. In this way, the water paths of the first coil 1 and the second coil 2 are connected in parallel and the air paths are connected in series.

[0037] In an embodiment of the present application, the first coil 1 includes a first water valve arranged at the water inlet 11 of the first coil 1; the second coil 2 includes a second water valve arranged at the water inlet 21 of the second coil 2; the control device connects the first water valve and the second water valve, and controls the switching status of the first water valve and the second water valve respectively.

[0038] In an embodiment of the present application, the control module controls the on and off states of the first coil and the second coil and linkage controls the speed of the fan according to the ambient temperature corresponding to the external environment of the air conditioner, the first water inlet temperature at the water inlet of the first coil, the first water outlet temperature at the water outlet of the first coil, the second water inlet temperature at the water inlet of the second coil, and the second water outlet temperature at the water outlet of the second coil.

[0039] In the embodiment of the present application, two coils with different diameters are arranged, and the air paths of the two coils are connected in series and the water paths are connected in parallel, that is, the two coils share a fan and an air duct and the water paths of the two coils are independent of each other. The independence of the water paths of the two coils can enable the two coils to have independent heat dissipation or cooling capabilities. In this way, the embodiment of the present application provides a dual-water air conditioner, and the heat exchange amount of the air conditioner can be adjusted by separately controlling the on and off states of the two coils and the speed of the fan, thereby adjusting the ambient temperature of the environment in which the air conditioner is located.

[0040] Based on the above air conditioning control system, an embodiment of the present application provides an air handling unit. The air handling unit is also called an air handling unit. The air handling unit is a terminal device of the air conditioning system. The air handling unit includes the above air conditioning control system.

[0041] Based on the above air conditioning control system, an embodiment of the present application provides an air conditioning control method. The execution subject of the embodiment of the present application is a control device in the air conditioning control system. Figure 2 Flow chart of an air conditioning control method according to an embodiment of the present application.

[0042] Step S210, obtaining temperature information corresponding to the external environment of the air conditioner and determining a target heat exchange amount of the air conditioner according to the temperature information.

[0043] The temperature information includes but is not limited to: the ambient temperature corresponding to the external environment of the air conditioner.

[0044] The target heat exchange refers to the theoretical heat exchange of the air conditioner.

[0045] Step S220, obtaining water temperature information corresponding to the internal environment of the air conditioner and determining the actual heat exchange capacity of the air conditioner according to the water temperature information.

[0046] The water temperature information includes but is not limited to: the water flow temperature corresponding to the internal environment of the air conditioner.

[0047] The actual heat exchange refers to the actual heat exchange that can be provided by the two water paths provided by the first coil and the second coil in the air conditioner.

[0048] Step S230, according to the target heat exchange amount and the actual heat exchange amount, respectively controlling the on / off state of the first coil and the second coil in the air conditioner and controlling the speed of the fan in the air conditioner in linkage.

[0049] The on-off state includes: connected state and disconnected state. The connected state means that water can flow through the coil. The disconnected state means that water cannot flow through the coil.

[0050] Due to the temperature difference between the water inlet temperature and the water outlet temperature of the coil inside the air conditioner and the air circulation conditions in the environment where the air conditioner is located, the target heat exchange amount and the actual heat exchange amount of the air conditioner will be different. Therefore, the embodiment of the present application controls the on and off states of the first coil and the second coil in the air conditioner respectively and controls the speed of the fan in the air conditioner in a linkage manner by comparing the target heat exchange amount and the actual heat exchange amount.

[0051] When the target heat exchange rate is greater than the actual heat exchange rate, it means that the actual heat exchange rate provided by the two water circuits of the air conditioner cannot reach the target heat exchange rate, and the actual heat exchange rate of the air conditioner is insufficient to meet the user's demand for heat exchange rate. At this time, the first coil and the second coil in the air conditioner are controlled to be in a connected state, and the fan in the air conditioner is controlled to operate at a preset first speed, so as to increase the heat exchange rate of the air conditioner.

[0052] When the target heat exchange amount is equal to the actual heat exchange amount, it means that the actual heat exchange amount provided by the two water circuits of the air conditioner meets the target heat exchange amount. At this time, the current on / off state of the first coil and the second coil and the current speed of the fan are maintained.

[0053] When the target heat exchange amount is less than the actual heat exchange amount, it means that the actual heat exchange amount provided by the two water circuits of the air conditioner has exceeded the target heat exchange amount, and the heat exchange amount of the air conditioner is too much. At this time, one of the first coil and the second coil in the air conditioner is controlled to be in a connected state, and the other coil is in a disconnected state, and the fan is controlled to operate at a speed corresponding to the coil in the connected state, so as to reduce the heat exchange amount of the air conditioner.

[0054] In an embodiment of the present application, the temperature information corresponding to the preset external environment of the air conditioner is obtained and the target heat exchange of the air conditioner is determined according to the temperature information; the water temperature information corresponding to the internal environment of the air conditioner is obtained and the actual heat exchange of the air conditioner is determined according to the water temperature information; according to the target heat exchange and the actual heat exchange, the on / off state of the first coil and the second coil in the air conditioner are respectively controlled, and the speed of the fan in the air conditioner is controlled in linkage. The water paths of the two coils in the embodiment of the present application are independent, so that the two coils can have the ability of independent heat dissipation or independent cooling respectively. In this way, by controlling the on / off state of the two coils and the speed of the fan respectively, the heat dissipation of the air conditioner can be adjusted, and then the ambient temperature of the environment where the air conditioner is located can be adjusted to meet the needs of users who want to change the indoor temperature at any time.

[0055] Furthermore, since the diameters of the two coils in the embodiment of the present application are different, the coil with a small diameter has a larger heat exchange capacity, and the coil with a large diameter has a smaller water resistance. Therefore, by controlling the opening of the coil with a small diameter and the opening of the coil with a large diameter separately, the air conditioner can obtain different heat exchange capacities, and different heat exchange capacities can adjust the environment where the air conditioner is located to different ambient temperatures; when both coils are controlled to be turned on, the superimposed heat exchange capacity of the two coils can be obtained, and the heat exchange speed is faster.

[0056] In order to make the embodiments of the present application clearer, the air conditioning control method of the embodiments of the present application will be further described below.

[0057] In the embodiment of the present application, after the air conditioner is started, the first water valve provided at the water inlet of the first coil is controlled to be opened, the second water valve provided at the water inlet of the second coil is controlled to be closed, and the fan is controlled to operate at a preset second speed; starting from the start of the air conditioner, the temperature information corresponding to the preset air conditioner external environment is obtained once every preset time period. That is, every preset time period, it is re-determined whether the on / off state of the first coil and the second coil and the speed of the fan need to be adjusted.

[0058] Furthermore, the length of the preset time period can be determined according to the requirements, for example, 120 seconds.

[0059] In an embodiment of the present application, temperature information corresponding to a preset air-conditioning external environment is obtained and a target heat exchange amount of the air-conditioning is determined according to the temperature information.

[0060] The temperature information includes: the ambient temperature corresponding to the external environment of the air conditioner.

[0061] Specifically, a set temperature corresponding to the external environment of the air conditioner is obtained; and a target heat exchange amount of the air conditioner is determined according to a difference between the set temperature and the ambient temperature, a preset air specific heat capacity, and a preset air mass.

[0062] The set temperature refers to the temperature set by the user, that is, the temperature the user hopes to achieve.

[0063] Furthermore, due to frequent adjustment of the on / off states of the first coil and the second coil, jitter may occur when detecting the water temperature. Therefore, when determining the target heat exchange, the capacity difference introduced by the jitter may be considered. In this way, the initial target heat exchange may be determined based on the difference between the set temperature and the ambient temperature, the preset air specific heat capacity, and the preset air quality; the absolute value of the difference between the initial target heat exchange and the preset capacity difference is calculated, and the absolute value of the difference is determined as the target heat exchange of the air conditioner.

[0064] For example, the following formula can be used to determine the initial target heat exchange capacity of the air conditioner:

[0065] Q = c × m × (Tout-Tin);

[0066] Among them, Q represents the initial target heat exchange amount; c represents the specific heat capacity of air; m represents the air quality; Tout represents the set temperature; Tin represents the ambient temperature. Among them, the number of ventilation times and the amount of air exchanged each time in the environment where the air conditioner is located within the preset time period can be determined; the product of the number of ventilation times and the amount of air exchanged can be multiplied by the preset air density to obtain the air quality.

[0067] Furthermore, a temperature value detected by a temperature sensor in the temperature sensor group for detecting the ambient temperature is obtained. The ambient temperature refers to the temperature of the environment where the air conditioner is located. For example, the indoor temperature where the air conditioner is located.

[0068] In an embodiment of the present application, water temperature information corresponding to the internal environment of the air conditioner is obtained and the actual heat exchange amount of the air conditioner is determined based on the water temperature information.

[0069] The water temperature information includes: a first water inlet temperature at the water inlet of the first coil, a first water outlet temperature at the water outlet of the first coil, a second water inlet temperature at the water inlet of the second coil, and a second water outlet temperature at the water outlet of the second coil.

[0070] Specifically, you can use Figure 3 Flow chart of the steps for determining the actual heat exchange amount shown.

[0071] Step S310, obtaining a first water inlet temperature at the water inlet of the first coil, a first water outlet temperature at the water outlet of the first coil, a second water inlet temperature at the water inlet of the second coil, and a second water outlet temperature at the water outlet of the second coil.

[0072] Step S320, determining the coil heat exchange amount corresponding to the first coil according to the difference between the first water inlet temperature and the first water outlet temperature, a preset air specific heat capacity, and a preset air mass; and determining the sum of the coil heat exchange amount corresponding to the first coil and the preset loss heat exchange amount as the actual heat exchange amount corresponding to the first coil.

[0073] Step S330, determining the coil heat exchange amount corresponding to the second coil according to the difference between the second water inlet temperature and the second water outlet temperature, the air specific heat capacity, and the air mass; and determining the sum of the coil heat exchange amount corresponding to the second coil and the lost heat exchange amount as the actual heat exchange amount corresponding to the second coil.

[0074] Step S340: Determine the sum of the actual heat exchange amount corresponding to the first coil and the actual heat exchange amount corresponding to the second coil as the actual heat exchange amount of the air conditioner.

[0075] Further, the first water inlet temperature at the water inlet of the first coil, the first water outlet temperature at the water outlet of the first coil, the second water inlet temperature at the water inlet of the second coil, and the second water outlet temperature at the water outlet of the second coil can be obtained according to the current on-off status of the first coil and the second coil; if the first coil is in the on-off status, the first water inlet temperature and the first water outlet temperature corresponding to the first coil are both detected temperature values; if the first coil is in the off-off status, the first water inlet temperature and the first water outlet temperature corresponding to the first coil are both 0. If the second coil is in the on-off status, the second water inlet temperature and the second water outlet temperature corresponding to the second coil are both detected temperature values; if the second coil is in the off-off status, the second water inlet temperature and the second water outlet temperature corresponding to the second coil are both 0.

[0076] For example, for each coil in the first coil and the second coil, the following formula can be used to determine the actual heat exchange amount corresponding to the coil:

[0077] Q'=Q P +Q S ;

[0078] Q P =c×m×(T 进 -T 出 );

[0079] Among them, Q' represents the actual heat exchange corresponding to the current coil; Q P Indicates the heat exchange rate of the coil corresponding to the coil, Q S represents the preset loss of heat; c represents the specific heat capacity of air; m represents the air mass; T 进 Indicates the water inlet temperature of the coil; T 出 Indicates the outlet water temperature of the coil.

[0080] Furthermore, the heat exchange loss is an empirical value or a value obtained through experiments.

[0081] Further, the temperature value detected by the temperature sensor for detecting the water temperature in the temperature sensor group is obtained. Further, the temperature values ​​detected by the temperature sensor at the water inlet of the first coil, the temperature sensor at the water outlet of the first coil, the temperature sensor at the water inlet of the second coil, and the temperature sensor at the water outlet of the second coil are obtained.

[0082] In an embodiment of the present application, according to the target heat exchange amount and the actual heat exchange amount, the on / off states of the first coil and the second coil in the air conditioner are controlled respectively, and the speed of the fan in the air conditioner is controlled in linkage.

[0083] Furthermore, it is possible to preset a first speed corresponding to when the first coil and the second coil are both in a connected state; preset a second speed corresponding to when the first coil is in a connected state and the second coil is in a closed state; and preset a third speed corresponding to when the first coil is in a closed state and the first coil is in a connected state. The speeds are in descending order: the first speed, the second speed, and the third speed.

[0084] When the target heat exchange amount is greater than the actual heat exchange amount, the first water valve set at the water inlet of the first coil is controlled to be opened, the second water valve set at the water inlet of the second coil is controlled to be opened, and the fan is controlled to operate at a preset first speed. Further, if the current on-off state of the first coil and the second coil is that both the first coil and the second coil are in a connected state, the first water valve at the water inlet of the first coil is maintained open and the second water valve at the water inlet of the second coil is maintained open; if the current on-off state of the first coil and the second coil is that one of the first coil and the second coil is in a connected state, the coil in the closed state is adjusted to a connected state, that is, the water valve corresponding to the coil is opened, and in addition, the speed of the fan needs to be adjusted to the first speed.

[0085] When the target heat exchange amount is equal to the actual heat exchange amount, the current on / off states of the first coil and the second coil in the air conditioner and the current rotation speed of the fan in the air conditioner are maintained.

[0086] When the target heat exchange amount is less than the actual heat exchange amount, determine the switch state of the first water valve set at the water inlet of the first coil and the switch state of the second water valve set at the water inlet of the second coil; when the first water valve and the second water valve are both open, control the second water valve to close and control the fan to operate at a preset second speed; when the first water valve is open and the second water valve is closed, control the first water valve to close, control the second water valve to open and control the fan to operate at a preset third speed; wherein the first speed is greater than the second speed, and the second speed is greater than the third speed. Of course, when the target heat exchange amount is less than the actual heat exchange amount, if the first water valve is closed and the second water valve is opened, then the first water valve can be kept closed and the second water valve can be kept open.

[0087] In the embodiment of the present application, the ambient temperature of the environment where the air conditioner is located can be obtained in real time; the set temperature and the ambient temperature are compared; according to the comparison result, the proportional-integral-derivative control (PID) method is used to adjust the opening of the water valve set at the water inlet of the coil that is currently in a connected state. For example: if the ambient temperature is greater than the set temperature, the opening of the water valve is controlled to decrease by a preset gradient value; if the ambient temperature is less than the set temperature, the opening of the water valve is controlled to increase the gradient value; if the ambient temperature is equal to the set temperature, the current opening of the water valve is adjusted. The gradient value can be an empirical value or a value obtained through experiments.

[0088] In order to make the embodiments of the present application easier to understand, a more specific example is provided below to further describe the air conditioning control method of the embodiments of the present application.

[0089] In this example, three gears are set, namely high gear, middle gear and low gear. In this example, the middle gear can be used as the default gear.

[0090] The high position corresponds to the maximum heat exchange amount. In the high position, the first water valve of the water inlet of the first coil is opened, the second water valve of the water inlet of the second coil is opened, and the fan adopts the first speed.

[0091] The middle position corresponds to a medium heat exchange amount. In the middle position, the first water valve of the water inlet of the first coil is opened, the second water valve of the water inlet of the second coil is closed, and the fan adopts the second speed.

[0092] The low gear corresponds to the minimum heat exchange amount. In the low gear, the first water valve of the water inlet of the first coil is closed, the second water valve of the water inlet of the second coil is opened, and the fan adopts the third speed.

[0093] In this example, automatic mode and manual mode are set. The automatic mode means automatically detecting whether the air conditioner needs to adjust the gear, and automatically adjusting the gear when it is determined that the gear needs to be adjusted. The manual mode means adjusting the gear of the air conditioner according to the gear selected by the user. For example: if the user wants to increase the heat exchange, the gear can be manually adjusted to a high gear, and if the user wants to reduce the heat exchange, the gear can be manually adjusted to a low gear.

[0094] like Figure 4 , which is a flowchart of steps in automatic mode according to an embodiment of the present application.

[0095] Step S410, after the air conditioner is started, it enters the middle gear as the default gear, that is: the first water valve of the water inlet of the first coil is controlled to be opened, the second water valve of the water inlet of the second coil is controlled to be closed, and the fan is controlled to operate at a second speed.

[0096] Step S420, after the air conditioner is started, the target heat exchange amount and the actual heat exchange amount of the air conditioner are determined at intervals of a preset time period.

[0097] For example: after the air conditioner has been running for 120 seconds, the temperature information corresponding to the preset external environment of the air conditioner is obtained and the target heat exchange capacity of the air conditioner is determined according to the temperature information; the water temperature information corresponding to the internal environment of the air conditioner is obtained and the actual heat exchange capacity of the air conditioner is determined according to the water temperature information.

[0098] Step S430: adjusting the current gear of the air conditioner by comparing the target heat exchange amount |QX| and the actual heat exchange amount Q' of the air conditioner.

[0099] If |QX|>Q', the high gear is entered, the first water valve at the water inlet of the first coil is controlled to open, the second water valve at the water inlet of the second coil is controlled to open, and the fan is controlled to operate at the first speed.

[0100] If |QX|=Q', the mid-range position is maintained.

[0101] If |QX|>Q', the low gear is entered, the first water valve at the water inlet of the first coil is controlled to be closed, the second water valve at the water inlet of the second coil is controlled to be opened, and the fan is controlled to operate at the third speed.

[0102] Under the current gear, continue to detect the ambient temperature in real time; compare the ambient temperature with the set temperature; according to the comparison result, perform PID control on the coil currently in the connected state to adjust the opening of the water valve set at the water inlet of the coil. For example: if the ambient temperature is greater than the set temperature, control the opening of the water valve to reduce the preset gradient value; if the ambient temperature is less than the set temperature, control the opening of the water valve to increase the gradient value; if the ambient temperature is equal to the set temperature, the current opening of the water valve is set.

[0103] Step S440: the air conditioner continues to operate and after a preset period of time, the target heat exchange amount and the actual heat exchange amount of the air conditioner are determined again.

[0104] After the air conditioner continues to run for 120 seconds, that is, after the air conditioner is started, at intervals of a preset time period, the temperature information corresponding to the preset air conditioner external environment is obtained and the target heat exchange rate of the air conditioner is determined according to the temperature information; the water temperature information corresponding to the air conditioner internal environment is obtained and the actual heat exchange rate of the air conditioner is determined according to the water temperature information; and the target heat exchange rate of the air conditioner (ie: |QX|) is compared with the actual heat exchange rate Q'.

[0105] Step S450, reading the current gear of the air conditioner, and adjusting the current gear of the air conditioner by comparing the target heat exchange amount and the actual heat exchange amount of the air conditioner.

[0106] If |QX|>Q', the current gear is identified; if the current gear is a high gear, the high gear is maintained; if the current gear is a medium gear or a low gear, a gear is raised. That is, if the current gear is a medium gear, it is adjusted to a high gear; if the current gear is a low gear, it is adjusted to a medium gear.

[0107] If |QX|=Q', the current gear is maintained.

[0108] If |QX|>Q', identify the current gear; if the current gear is a low gear, maintain the low gear; if the current gear is a high gear or a medium gear, adjust down a gear. That is, if the current gear is a high gear, adjust to the medium gear; if the current gear is a medium gear, adjust to the low gear.

[0109] In this example, after executing step S450, the process jumps to step S440 until the air conditioner stops running.

[0110] In this example, the fan may use a variable frequency motor, which may be a three-speed motor that adjusts the motor speed according to the carbon dioxide range value.

[0111] This application designs a terminal equipment structure of a dual-water air conditioner, and on this basis, controls the water flow and fan by variable flow and variable air volume to achieve a control method for heat exchange conditions (cooling capacity or heating capacity), thereby adjusting the air volume and heat of the air conditioner to meet the different cooling and heating load requirements of users in different time periods.
