In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by referring to the following examples.
As shown in fig. 1, in the machine room refrigeration system provided in the embodiment of the present invention, a plurality of rows of cabinet groups 10 and a plurality of air conditioners (not shown in the figure) are disposed in a machine room, a closed channel 20 is formed between two adjacent rows of cabinet groups 10, the plurality of air conditioners are disposed between cabinets 11 of each row of cabinet groups 10 in an inserting manner, an air inlet and an air outlet of an air conditioner are respectively communicated with the closed channels 20 on two sides of the cabinet group 10 where the air conditioner is located, and the machine room refrigeration system includes:
at least one sensor correspondingly arranged with the closed channel 20 formed by two adjacent columns of cabinet groups 10, and a controller connected with each sensor and each air conditioner; wherein,
for each closed channel 20, the controller obtains a parameter value for measuring the pressure difference between the inside and the outside of the closed channel 20 according to the induction value of at least one sensor arranged corresponding to the closed channel 20, compares the parameter value with a preset threshold value to obtain a comparison result, and adjusts the rotating speed of the fan of the air conditioner arranged corresponding to the closed channel 20 according to the comparison result.
In the embodiment of the present invention, the closed channel 20 may refer to a closed cold channel communicated with an air inlet of an air conditioner, or may refer to a closed hot channel communicated with an air outlet of the air conditioner. Heat generated by the operation of the server cabinet in the machine room is blown into the closed hot channel through the server fan, then hot air in the closed hot channel enters the air conditioner through the air inlet of the air conditioner, and is blown into the closed cold channel through the air outlet by the fan of the air conditioner after being cooled by the air conditioner, so that the server cabinet is cooled, and primary circulation is completed. For a closed cold channel, the air conditioner arranged corresponding to the closed cold channel is an air conditioner with an air outlet communicated with the channel, and correspondingly, for a closed hot channel, the air conditioner arranged corresponding to the closed hot channel is an air conditioner with an air inlet communicated with the channel.
In the technical scheme of the embodiment of the invention, the static pressure fluctuation condition in the closed channel 20 can be accurately detected by measuring the parameter value of the pressure difference between the inside and the outside of the closed channel 20, so that the rotating speed of the air conditioner fan, namely the air supply quantity of the air conditioner can be quickly adjusted, and the air pressure in the closed channel 20 can be kept in a micro-positive pressure state relative to the air pressure outside the closed channel 20.
Specifically, adjust the rotational speed of the fan of the air conditioner that corresponds the setting with this closed passage according to the comparative result, include: when the parameter value is larger than a preset threshold value, controlling the rotating speed of a fan of the air conditioner to be reduced; and controlling the rotating speed of the fan of the air conditioner to rise when the parameter value is smaller than the preset threshold value.
In the technical scheme of this embodiment, taking a closed cold channel as an example, when a parameter value is greater than a preset threshold value, it is described that air pressure in the closed cold channel is higher than air pressure outside the closed cold channel, and the amount of cold air blown into the closed cold channel by an air conditioner fan is greater than the amount of hot air blown into a closed hot channel by a server fan, so that the air supply amount of the air conditioner fan is greater than the heat dissipation requirement of equipment, and at this time, in order to avoid cold waste, the rotating speed of the air conditioner fan needs to be controlled to be; when the parameter value is smaller than the preset threshold value, the air pressure in the closed cold channel is lower than the air pressure outside the closed cold channel, the cold air quantity blown into the closed cold channel by the air conditioner fan is smaller than the hot air quantity blown into the closed hot channel by the server fan, and at the moment, in order to enable the air supply quantity of the air conditioner fan to meet and quickly match the heat dissipation requirement of equipment, the air leakage phenomenon of the closed cold channel is reduced, and the rotating speed of the air conditioner fan needs to be controlled to rise.
The specific type of the sensor is not limited, as long as the parameter value for measuring the pressure difference between the inside and the outside of the closed channel can be obtained through the induction value of the sensor. For example, as shown in fig. 1 and 2, in a preferred embodiment of the present invention, the sensor is a wind speed sensor, the top cover plate 21 of the enclosed channel 20 is provided with an opening 30 for receiving a probe 40 of the wind speed sensor, and the probe 40 of the wind speed sensor is disposed toward the enclosed channel 20. Therefore, the pressure difference between the inside and the outside of the closed channel 20 can be sensed by detecting the air flow rate at the opening 30, specifically, when the sensor detects a forward wind speed signal, the inside of the closed channel 20 is in a positive pressure state relative to the outside of the closed channel 20, and when the sensor detects a reverse wind speed signal, the inside of the closed channel 20 is in a negative pressure state relative to the outside of the closed channel 20. At this time. The preset threshold value is an evaluation standard corresponding to the wind speed, can be determined empirically and is prestored in the controller, and when the forward wind speed is greater than the preset threshold value, the rotating speed of the air conditioner fan is controlled to be reduced; and when the forward wind speed is smaller than a preset threshold value or the sensor detects a reverse wind speed signal, namely the forward wind speed value is negative, controlling the rotating speed of the air conditioner fan to rise. The specific type of the wind speed sensor is not limited, and may be, for example, a vane type, a thermo-bulb type, a hot wire type, or a hot film type, etc.
In this case, it is also necessary to provide an opening for receiving the probe of the air flow sensor in the top cover plate of the closed duct, and to dispose the probe of the air flow sensor toward the closed duct. The control principle of the air flow sensor is similar to that of the wind speed sensor, and is not described in detail herein.
In another preferred embodiment of the present invention, as shown in fig. 3, the sensor is a differential air pressure sensor, the top cover plate 21 of the closed channel 20 is provided with a first static pressure port 50 communicated with the inside of the closed channel 20 and a second static pressure port 60 communicated with the outside of the closed channel 20, the positive pressure port of the differential air pressure sensor is connected with the first static pressure port 50, and the negative pressure port is connected with the second static pressure port 60. Therefore, the pressure difference between the inside and the outside of the closed channel 20 can be directly detected through the air pressure difference sensor, at the moment, the preset threshold is an evaluation standard corresponding to the pressure difference, the preset threshold can be determined according to experience and is prestored in the controller, and when the measured pressure difference is larger than the preset threshold, the rotating speed of the air conditioner fan is controlled to be reduced; and when the measured pressure difference is smaller than a preset threshold value, controlling the rotating speed of the air conditioner fan to rise.
In addition, in order to reduce the influence of the air conditioner fan and the cabinet fan on the detection result of the sensor, the sensor is arranged on the closed channel and can avoid the area blown by the air conditioner fan and the cabinet fan.
In a preferred embodiment of the present invention, a plurality of sensors are correspondingly disposed in a closed channel formed by two adjacent rows of cabinet groups, and a controller obtains a parameter value for measuring a pressure difference between inside and outside of the closed channel according to an induction value of at least one sensor correspondingly disposed in the closed channel, specifically including: the controller takes the average value of the sensing values of the sensors as a parameter value for measuring the pressure difference between the inside and the outside of the closed channel. In other embodiments of the present invention, the maximum value or the minimum value of the sensing values of the plurality of sensors may also be used as a parameter value for measuring the pressure difference inside and outside the closed channel, which may be determined according to the use requirement of the customer.
In a preferred embodiment of the present invention, the controller is further configured to: detecting whether at least one sensor arranged corresponding to a closed channel formed by two adjacent rows of cabinet groups is completely failed or not; and under the condition that the sensors are not completely failed, acquiring a parameter value for measuring the pressure difference between the inside and the outside of the closed channel according to the induction value of the effective sensor. By adopting the technical scheme, the sensor which is out of work can be eliminated in advance by detecting whether the sensor can work normally or not, so that the detection data of the sensor which is out of work is prevented from influencing a comparison result, and the control precision of the air supply quantity of the air conditioner fan can be improved. It is worth mentioning that in the embodiment of the present invention, whether a sensor fails or not may be determined according to whether it can detect a sensing value or not. Preferably, the controller is further configured to send an alarm prompt under the condition that at least one sensor fails, so that a user can be reminded of an abnormal working state of the refrigeration system of the machine room, and the failed sensor can be replaced in time.

Therefore, when the sensor cannot be used for acquiring the parameter value for measuring the internal and external pressure difference of the closed channel, the rotating speed of the air conditioner fan can be adjusted by utilizing the temperature information of the air inlet and the air outlet of the air conditioner, and the working reliability of the system is improved.
