[0028] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. For example, although the utility model is explained in conjunction with the precision air conditioner in the computer room, the precision air conditioner in the computer room of the utility model can obviously also be applied to construction equipment, smart home equipment and industrial production equipment, etc. This change in the application object does not deviate from the technical solution of the utility model and should be limited to the scope of protection of the utility model.

[0029] At present, the far-infrared humidifier and wet film humidifier of the precision air conditioning in the computer room need to be equipped with their own controllers, and the installation structure and installation method of each controller are quite different. In the actual application of the precision air conditioning in the computer room, when selecting and switching the far-infrared humidifier and the wet film humidifier, the current controller of the wet film humidifier and the controller of the far-infrared humidifier are independently controlled, which may cause the problem of poor substitutability of the controllers in specific scenarios, and inconvenient replacement and maintenance.

[0030] Based on this, an embodiment of the utility model provides a precision air conditioner for a computer room and its control system, which controls a far-infrared humidifier and a wet film humidifier through one controller, and can realize switching without changing the controller structure, thereby facilitating user use and improving user experience.

[0031] The following is a detailed description through examples.

[0032] Figure 1 A structural block diagram of a precision air conditioner for a computer room provided in an embodiment of the utility model.

[0033] Reference Figure 1 The precision air conditioner for the computer room includes: a central control processing unit, a far-infrared humidifier, a wet film humidifier and a selection switch; the central control processing unit includes a first instruction output interface, and the selection switch includes an input end, a first output end and a second output end; wherein the selection switch can be understood as a switch component with a selection function such as a contactor coil or the like;

[0034] The first command output interface is connected to the input end, the first output end is connected to the wet film humidifier, and the second output end is connected to the far infrared humidifier;

[0035] Under the action of the first command output interface and the selection switch, the far-infrared humidifier or the wet film humidifier is controlled to work.

[0036] In a preferred embodiment of actual application, the wet film humidifier or the far-infrared humidifier shares a central control processing unit; the first command output interface of the central control processing unit can be selectively connected to the wet film humidifier or the far-infrared humidifier through a selection switch, and the first command output interface can output control commands connected to the wet film humidifier and control commands connected to the far-infrared humidifier, thereby triggering the selection switch to switch to the corresponding humidifier type, which is more convenient.

[0037] In actual applications, when the wet film humidifier is connected to the central control processing unit, the humidifying wet film can be connected to the first command output interface; when the far-infrared humidifier is connected to the central control processing unit, the far-infrared lamp can be connected to the first command output interface; the first command output interface can also be an integrated output interface, that is, it can be connected to the humidifying wet film or the far-infrared lamp, that is, the first command output interface is also a wet film / lamp contactor coil control interface including a selection switch, through which the wet film / far-infrared lamp contactor coil control interface can be used to transmit the wet film humidification control command of the control processing unit to the humidifying wet film, and the far-infrared humidification command of the control processing unit to the far-infrared lamp. Of course, the aforementioned integrated output interface can also be replaced by two independent command output interfaces, and each actuator is connected to a corresponding command output interface. In addition, in actual applications, if the wet film humidifier or far-infrared humidifier has other humidification actuators, the number of interfaces in the first instruction output interface component can be increased, so that all control instructions of the control processing unit can be sent to all humidification actuators in the wet film humidifier or far-infrared humidifier through the corresponding interface.

[0038] Through such a setting, the present application only needs to set up a mounting structure for installing the central control processing unit in specific scenarios (such as the installation and application of precision air conditioners in computer rooms, etc.), and there is no need to disassemble the central control processing unit when the precision air conditioner in the computer room changes the type of humidifier. It is only necessary to connect the humidifier to the corresponding interface component on the central control processing unit, which is convenient for users to use. When replacing the central control processing unit, it is only necessary to remove the original central control processing unit and install a new central control processing unit in the original position. When repairing the central control processing unit, it is only necessary to remove the central control processing unit and install it back to the original position after repair. The central control processing unit has good substitutability, is convenient for users to use, and improves user experience. In addition, the central control processing unit can achieve production consistency, high degree of production standardization, and high production efficiency.

[0039] As an optional embodiment, the central control processing unit can be set up separately or integrated with the controller of the precision air conditioner in the computer room. Technical personnel in this field can flexibly set the setting mode of the central control processing unit in actual applications, as long as the central control processing unit can control both the wet film humidifier and the far-infrared humidifier.

[0040] It should be noted that the wet film humidifier includes a humidifying chamber, a humidifying film, a current transformer, a high water level sensor, a water inlet valve and a drain valve. The humidifying chamber is used to hold water. The humidifying film is inserted into the water to heat the water. The current transformer can detect the current between the humidifying films. The high water level sensor can detect the high water level in the humidifying chamber. The water inlet valve and the drain valve are used to control the water inlet and outlet of the humidifying chamber. The far-infrared humidifier includes a humidifying chamber, a far-infrared humidifying lamp, a water inlet valve, a drain valve (the drain valve may not be provided), a high water level sensor, a low water level sensor and a thermal protection switch. The humidifying chamber is used to hold water. The far-infrared humidifying lamp heats the water by far-infrared radiation. The water inlet valve and the drain valve are used to control the water inlet and outlet of the humidifying chamber. The high water level sensor can detect the high water level in the humidifying chamber. The low water level sensor can detect the low water level in the humidifying chamber. The thermal protection switch can prevent overheating and dry burning.

[0041] Among them, the wet film humidifier inserts an energized wet film into water, uses water as a conductive resistor, heats the water to boiling, generates clean steam, and thus humidifies the air. By controlling the water inlet and outlet, the water level in the humidification chamber can be changed to change the humidification amount. Proportional control or switch control can be used, and its structure specifically includes an inlet valve, a drain valve, a heated wet film, a high water level wet film, and a humidifying current transformer, etc.; the far-infrared humidifier uses the far-infrared radiation energy generated by the far-infrared lamp tube when it is energized to heat and vaporize water. It generally uses switch control, and its structure specifically includes an inlet valve, a drain valve (optional), a far-infrared lamp tube, a thermal protection switch, and a high and low water level switch, etc.

[0042] On the basis of the above-mentioned embodiment, the central control processing unit further comprises a first parameter input interface and a second parameter input interface; the first parameter input interface and the second parameter input interface are respectively connected to the wet film humidifier;

[0043] The first parameter input interface is used to receive a humidification current detection signal of a wet film humidifier;

[0044] The second parameter input interface is used to receive a high water level wet film detection signal of the wet film humidifier.

[0045] In practical applications, when the wet film humidifier is connected to the central control processing unit, the current transformer can be connected to the first parameter input interface, and the high water level sensor can be connected to the second parameter input interface, that is, the first parameter input interface is the humidification current detection interface of the wet film humidifier, and the second parameter input interface is the high water level detection interface of the wet film humidifier. The current detected by the current transformer is transmitted to the central control processing unit through the humidification current detection interface, and the water level information detected by the high water level sensor is transmitted to the central control processing unit through the high water level detection interface. Of course, in practical applications, if the wet film humidifier has other detection elements, the number of interfaces in the first parameter input interface component can be increased, so that the information detected by all detection elements in the wet film humidifier can be transmitted to the central control processing unit through the corresponding interface.

[0046] On the basis of the above-mentioned embodiment, the central control processing unit further comprises a third parameter input interface; the third parameter input interface is respectively connected to the far-infrared humidifier;

[0047] The third parameter input interface is used to receive a high water level detection signal, a low water level detection signal and a thermal protection detection signal of the far-infrared humidifier.

[0048] In actual applications, when the far-infrared humidifier is connected to the central control processing unit, the high water level sensor, the low water level sensor and the thermal protection switch can be connected to the third parameter input interface at the same time. At this time, the third parameter input interface can be set as an integrated input interface (that is, sharing one interface, because the type of access signal is consistent), that is, the third parameter input interface is a high water level detection, a low water level detection, and a thermal protection detection input interface. The high water level detected by the high water level sensor, the low water level detected by the low water level sensor, and the information detected by the thermal protection switch are transmitted to the control processing unit through the high water level detection, the low water level detection, and the thermal protection detection input interface. Of course, the aforementioned integrated interface can also be replaced by three independent parameter input interfaces, and each detection element is connected to a corresponding parameter input interface. In addition, if the far-infrared humidifier has other detection elements, the number of interfaces in the second parameter input interface component can be increased, so that the information detected by all detection elements in the far-infrared humidifier is transmitted to the control processing unit through the corresponding interface.

[0049] It can be understood that the above-mentioned first parameter input interface and the second parameter input interface can be integrated into only one interface, or can be dispersed into multiple interfaces for connection with a wet film humidifier. The third parameter input interface can have only one interface or multiple interfaces, which is used to connect with a far-infrared humidifier. The first command output interface can have only one interface or multiple interfaces, which is used to switch the connection between the wet film humidifier and the far-infrared humidifier, that is, it can be connected to a wet film humidifier alone or to a far-infrared humidifier alone. Technical personnel in this field can flexibly set the number of interfaces and the installation and connection method of the first parameter input interface, the second parameter input interface, and the first command output interface in actual applications, as long as the present application can control both the wet film humidifier and the far-infrared humidifier.

[0050] Furthermore, the present application also includes a drain switch arranged on the housing or control panel of the central control processing unit, which is used to generate action instructions; the central control processing unit also includes a drain instruction input interface, which is used to receive action instructions and control the drainage operation of the far-infrared humidifier or wet film humidifier.

[0051] Among them, the drainage command input interface is selectively connected to the drainage switch, wherein the drainage switch can be a part of the central control processing unit, that is, the drainage switch is arranged on the casing or control panel of the central control processing unit. Of course, the drainage switch can also be arranged at other positions of the precision air conditioner in the computer room. As long as it can be manually controlled to make the drainage switch trigger an action, an action command is generated, and the action command is transmitted to the central control processing unit through the drainage command input interface, the central control processing unit can finally control the wet film humidifier or far-infrared humidifier to perform drainage operations.

[0052] It should be noted that after the humidifier has been used for a period of time, the present application can control the drainage of the humidifier by operating the drain switch to avoid scale accumulation in the humidifier and affect the humidification performance of the humidifier. At the same time, forced drainage can also be performed when the humidifier is repaired and replaced, thereby facilitating users to repair and replace the humidifier and further improving the user experience.

[0053] In some embodiments, the central control processing unit also includes a water inlet and outlet control interface, which is respectively connected to the drain valve and water inlet valve of the far-infrared humidifier, and the drain valve and water inlet valve of the wet film humidifier, for outputting drain valve control instructions and water inlet valve control instructions.

[0054] It should be noted that at the same time, the drainage control interface can output the drainage valve control instruction of the wet film humidifier, or the water inlet valve control instruction of the wet film humidifier, or the drainage valve control instruction of the far-infrared humidifier, or the water inlet valve control instruction of the far-infrared humidifier.

[0055] The water inlet and water discharge control interface can be implemented through one interface or through multiple interfaces; it can output water inlet valve control instructions and water discharge valve control instructions. In practical applications, when the wet film humidifier is connected to the central control processing unit, the water inlet valve and water discharge valve of the wet film humidifier can be connected to the water inlet and water discharge control interface; when the far infrared humidifier is connected to the central control processing unit, the water inlet valve and water discharge valve of the far infrared can be connected to the water inlet and water discharge control interface; that is, through the water inlet and water discharge control interface, the water inlet and water discharge control instructions of the central control processing unit can be transmitted to the water inlet valve and water discharge valve of the wet film humidifier, and the water inlet and water discharge control instructions of the control processing unit can be transmitted to the water inlet valve and water discharge valve of the far infrared humidifier.

[0056] As an optional embodiment, the central control processing unit also includes an alarm output interface connected to the alarm device for outputting an alarm instruction.

[0057] Here, by setting an alarm output interface, an alarm command can be output, so that an alarm command can be issued in time when the humidifier fails or is damaged, which is convenient for maintenance personnel to check and repair, avoids affecting the normal use of the humidifier, and further improves the user experience.

[0058] Furthermore, the alarm output interface can be selectively connected to the alarm indicator light, and the alarm output signal can provide normally open and normally closed signal types through the passive dry contact of the relay, and be indicated by the alarm indicator light. Among them, the alarm indicator light can be set on the central control processing unit, and can also be placed in other locations of the precision air conditioner in the machine room so that the user can see it clearly.

[0059] In some embodiments, the central control processing unit further includes a signal input interface; the signal input interface is used to receive external control instructions and control the humidification operation of the far-infrared humidifier or the wet film humidifier.

[0060] The signal input interface can receive control instructions for controlling the wet film humidifier and the far-infrared humidifier. The controller of the precision air conditioner in the computer room can transmit control instructions to the central control processing unit through the signal input interface, thereby controlling the humidifier to perform humidification operations. Specifically, the signal type of the signal input interface can be a switch signal, a voltage analog signal (such as a 0-10V analog signal, a 0-5V analog signal, or a 2-10V analog signal, etc.) and a current analog signal (such as a 4-20mA analog signal or a 0-20mA analog signal, etc.), wherein the switch signal is for switch control of the humidifier, and the voltage analog signal and the current analog signal are for proportional control of the humidifier.

[0061] Furthermore, the central control processing unit also includes a communication interface for connecting to a host computer and receiving control instructions issued by the host computer.

[0062] A communicator can be connected to the communication interface, and the communicator can communicate with a host computer, such as the controller of the precision air conditioner in the computer room or the controller in the central control room, so as to receive control instructions issued by the controller of the precision air conditioner in the computer room or the controller in the central control room through the communicator and the communication interface. In addition, information can also be sent to the controller of the precision air conditioner in the computer room or the controller in the central control room through the communicator and the communication interface to report the working status of the humidifier.

[0063] like Figure 2 In the embodiment shown, the first parameter input interface Z1 is used to detect the humidification current of the wet film humidifier, and the second parameter input interface COM is used to detect the high water level of the wet film humidifier; the third parameter input interface X1 is used to detect the high water level, low water level and thermal protection of the far-infrared humidifier; the input end SZ of the first parameter output interface L11 can be selectively connected to the first output end 1, so that the central control processing unit is connected to the wet film humidifier, and the input end SZ of the first parameter output interface L11 can be selectively connected to the second output end 2, so that the central control processing unit is connected to the far-infrared humidifier; the drainage instruction input interface and the water inlet and water discharge control interface K1K2K3 control the water inlet valve and the water discharge valve; the alarm output interface RARBRC controls the fault alarm output;

[0064] It should be noted that all input and output interfaces of the present application may be in the form of terminals, and preferably plug-in connection terminals, so as to facilitate on-site installation and replacement.

[0065] The working principles of wet film humidifier and far infrared humidifier are explained below.

[0066] When the wet film humidifier is connected to the central control processing unit, the humidifying film in the wet film humidifier is energized and heated by the humidifying film contactor coil being turned on and attracted. The humidifying current is detected by the current transformer to control the action of the water inlet valve and the drain valve. When the current is less than a certain value of the humidifying rated current, the water inlet valve opens to replenish water into the humidifying chamber. As the water level increases, the humidifying current increases. When the current exceeds a certain value of the rated current, the water inlet valve closes and stops water inlet. When the water level of the inlet reaches the high water level, the drain valve is opened to drain and flush. When the humidifier has alarms such as current overload, low current, and high water level, an alarm signal is sent out. All processes are controlled by the control processing unit. When the far-infrared humidifier is connected to the central control processing unit, the far-infrared humidification lamp in the far-infrared humidifier is powered on by the lamp contactor coil for radiant heating. The water level float switch of the humidifier controls the action of the water inlet valve and the drain valve. When the water level is lower than the low water level, the water inlet valve opens to replenish water into the humidification chamber. As the water level increases and reaches the high water level, the high water level switch signal is connected, the water inlet valve is closed, and the water inlet stops. As the humidification proceeds, the water evaporates continuously, the water level drops, and when it reaches the low water level, it starts to replenish water again. This cycle repeats and humidifies continuously. At the same time, the state of the thermal protection switch is constantly monitored. In extreme cases, such as dry burning and overheating, the thermal protection switch is disconnected, the humidification contactor is disconnected to stop humidification, and an alarm signal is sent to the outside world. All processes are controlled by the control processing unit. Whether a wet film humidifier or a far-infrared humidifier is used, impurities and scale will appear after a period of use. At this time, the humidification chamber can be cleaned by forcing drainage through the drain switch. At the same time, in order to facilitate compatibility with the coil voltages of the water inlet valve and drain valve of each humidifier, the outputs are all in the form of relays, providing passive dry nodes.

[0067] In addition, in addition to the records of the aforementioned embodiments, the computer room precision air conditioner of the present application also includes an outer shell, cooling and heating and other temperature adjustment control components. The specific implementation can adopt the implementation method in the prior art, which can be known by technical personnel in this field to realize the corresponding functions of the computer room precision air conditioner in actual applications.

[0068] In some embodiments, the embodiments of the utility model further provide a computer room precision air conditioning control system, comprising at least one computer room precision air conditioner as described above, and also comprising a host computer connected to the computer room precision air conditioner.
