As shown in fig. 1, an embodiment of the present disclosure provides a cabinet including an equipment area 110, a refrigeration area 120, an air conditioning terminal 130, and one or more electronically commutated EC fans 140.
Wherein the equipment area 110 and the refrigeration area 120 are located side-by-side. A partition may be provided between the equipment area 110 and the refrigerated area 120. Therefore, the hot air from the air return opening of the refrigeration area can be prevented from directly entering the equipment area without passing through the tail end of the air conditioner, and the temperature in the equipment area cannot be reduced.
Wherein the device area 110 is provided with communication devices. The air conditioning terminal 130 is located within the refrigerated area 120. One or more EC fans 140 are located at the outlet of refrigeration zone 120, and one or more EC fans 140 are arranged above the bottom of the cabinet in sequence from top to bottom.
Further, a cool air passage compartment 150 is provided between the equipment area 110 and a cabinet door of the cabinet. A hot air duct compartment 160 is provided between the equipment area 110 and the back panel of the cabinet.
The cold air passage compartment 150 is communicated with an air outlet of the refrigeration area 120, and the hot air passage compartment 160 is communicated with an air return inlet of the refrigeration area 120.
The following is a description of the operation of the various components of the cabinet when the air conditioner is operating normally, in conjunction with the cabinet shown in fig. 1.
1. The cabinet opens multiple sets of EC fans 140.
Under the condition that the air conditioner normally works, the power supply mode of the EC fan 140 is the mains supply.
It should be noted that, under the condition that the air conditioner normally works, the inside of the cabinet is in a closed state.
2. Cool air at the outlet of refrigeration area 120 is forced through cool air duct compartment 150 into equipment area 110 by rotation of EC fan 140. Thus, in the equipment area 110, the cool air can exchange heat with the heat generated by the communication equipment, resulting in air with a higher temperature.
3. The heated air is blown through the hot air path compartment 160 towards the return air inlet of the refrigeration zone 120.
Therefore, airflow circulation can be formed in the cabinet, the overhigh temperature in the cabinet can be avoided, and the normal operation of the communication equipment arranged in the cabinet is ensured.
In order to increase the area of the air outlet of the cooling region 120 and improve the cooling efficiency, the air conditioning terminal 130 may be disposed in the cooling region 120 in an inclined manner. The air outlet of the refrigeration zone 120 is at the same height as the cabinet.
For example, as shown in fig. 1, the angle between the air conditioner terminal 130 and the side of the cabinet may be a first predetermined angle, and the first predetermined angle may be 15 degrees, 30 degrees, 45 degrees, and the like, without limitation.
Further, the width of the air outlet of the refrigeration area 120 can be set as required to adjust the air output of the air outlet.
Based on the technical scheme, the refrigeration area of the cabinet is provided with an equipment area and a refrigeration area which are arranged side by side, the equipment area is provided with communication equipment, and the refrigeration area is provided with an air conditioner terminal. So, the air conditioner end can imbed the rack, and the air conditioner end of embedding rack sets up the cooling region with the mode of slope, and the air outlet in cooling region is the same with the height of rack. The area of the air supply opening can be increased, the air outlet speed can be obviously reduced under the condition that the air supply quantity is fixed, and then the noise of air supply airflow is reduced.
In one possible design, a temperature sensor 170 is also provided at the return air inlet of the refrigerated area 120 in order to collect the return air temperature from the hot air path compartment 160.
In one possible design, in order to flexibly adjust the EC fans 140 to meet the cooling requirements of the equipment area 110, the cabinet is further provided with a controller, a comparator and a timer, the controller is connected with the temperature sensor 170, and the controller, the comparator and the timer are electrically connected with each other. The controller may be configured to control the speed of EC fan 140 based on the temperature sensed by temperature sensor 170.
The workflow of the controller, the comparator and the timer is explained below.
1. The temperature sensor 170 collects the return air temperature and sends the collected return air temperature to the comparator. Accordingly, the comparator receives the return air temperature from the temperature sensor 170.
2. The comparator compares the first temperature acquired by the temperature sensor with a preset threshold value, and sends a first signal to the timer under the condition that the first temperature acquired by the temperature sensor is greater than or equal to the preset threshold value. The first signal is used for triggering a timer to start timing. The preset threshold value may be set as desired. For example, the preset threshold may be 40 degrees, 45 degrees, 50 degrees, etc.
Further, the comparator may send a second signal to the timer in case that the first temperature collected by the temperature sensor is less than the preset threshold. The second signal is used for triggering the timer to stop timing.
3. The timer starts timing after receiving the first signal, and sends overtime reminding information to the comparator under the condition that the timing duration is longer than a first preset duration and the second signal is not received.
The first preset time can be set as required. For example, it may be 1 minute, 2 minutes, or the like.
4. The comparator may send a first signal to one or more EC fans 140 after receiving the timeout alerting message.
Wherein the first signal is used to trigger an increase in the rotational speed of one or more EC fans 140 to increase the cooling capacity of equipment area 110.
5. The controller may increase the rotational speed of the plurality of sets of EC fans 140 after receiving the third signal sent by the comparator.
In one possible design, multiple sets of EC fans 140 may be provided with corresponding fan motors. The fan motor is connected with the controller. The fan motors may be used to control the rotational speed of multiple sets of EC fans 140. For example, the fan motor may be provided with a plurality of wind speed control gears, and the rotation speeds of the EC fan 140 corresponding to different wind speed control gears are different.
The controller may send a fourth signal to the fan motor after receiving the third signal. The fourth signal can be used for triggering the fan motor to increase the wind speed control gear of the fan motor. For example, the fan motor may increase the current wind speed control gear by one gear (e.g., from one gear to two gears) after receiving the fourth signal.
6. After increasing the speed of one or more EC fans 140 for a second predetermined period of time, if the return air temperature is still greater than or equal to the predetermined threshold, the controller may increase the speed of the compressor speed corresponding to the air conditioning terminal 130 to further increase the cooling capacity of the equipment region 110.
The second preset duration may be the same as the first preset duration, or may be different from the first preset duration, which is not limited.
Further, if the return air temperature is less than the preset threshold, the comparator may send a fifth signal to the controller. The fifth signal is used to trigger a reduction in the rotational speed of the sets of EC fans 140. Thus, the power consumption of the EC fan 140 can be reduced.
In this manner, the controller may determine whether the current cooling capacity meets the cooling demand of equipment region 110 based on the return air temperature, and may increase the compressor speed for one or more EC fans 140 and air conditioning terminals 130 to increase the cooling capacity of equipment region 110. The temperature of the cabinet is prevented from rising, and the normal operation of the communication equipment arranged on the cabinet is prevented from being influenced.
It should be noted that the opening or closing of the first emergency air valve and the second emergency air valve may be controlled by a controller.
In a possible design, since the air outlet of the refrigeration area 120 may generate condensed water, in order to avoid the condensed water from affecting the communication equipment in the cabinet, as shown in fig. 2, a condensed water collecting tank 121 and a drain pipe 122 are further disposed at the bottom of the air conditioner terminal 130, a water inlet of the drain pipe 122 is communicated with the condensed water collecting tank 121, and a water outlet of the drain pipe 122 is disposed outside the cabinet.
In one possible design, to better direct the cold air to the equipment area 110, the air outlet of the refrigerated area 120 is also provided with a deflector 180, as shown in fig. 1.
Therefore, cold air can directly blow to the equipment area 110 through the flow guide sheet 180, so that the cold air loss can be reduced, and the refrigeration efficiency of the equipment area 110 is improved.
It should be noted that the constituent structures shown in fig. 1 and 2 do not constitute limitations on the cabinet, and the cabinet may include more or less components than those shown in fig. 1 and 2, or some components may be combined, or a different arrangement of components may be used, in addition to the components shown in fig. 1 and 2.
