Description

Technical Field

[0001] The present invention relates to the technical field of collaborative control, and in particular to a method for collaboratively controlling the operation of an air conditioning and ventilation system in a data center. Background Art

[0002] With the increase of data in various institutions, many institutions have set up their own data centers. Data centers are spaces where computer systems and other supporting equipment are placed. Data centers are also equipped with data communication connections, environmental control equipment, monitoring equipment, and various safety devices. Since there are many electronic devices in data centers, electronic devices will emit heat when working. In order to ensure that electronic devices can work normally, the temperature of the data center usually needs to be controlled within a certain range, which requires the use of air conditioning and ventilation systems.

[0003] Currently, data centers manually detect the indoor temperature of the data center, and then managers judge whether temperature adjustment is needed based on experience. This method not only requires managers to monitor at all times, but also relies on the management's experience, which leads to insufficient timeliness and reliability of temperature adjustment. Summary of the invention

[0004] The object of the present invention is to provide a method for coordinated control of the operation of air conditioning and ventilation systems in a data center to solve the problems raised in the above-mentioned background technology.

[0009] Determine whether the temperature difference belongs to a preset temperature difference level, and control the operation of the air conditioning and ventilation system according to the temperature difference level.

[0010] As a further solution of the present invention: the data center air conditioning and ventilation system operation coordinated control method further includes:

[0014] If the real-time humidity is greater than the specified humidity, the air conditioner turns on the "dehumidification mode";

[0015] If the real-time humidity is lower than the specified humidity, the air conditioner turns on the "humidification mode".

[0016] As a further solution of the present invention: the step of determining that the temperature difference belongs to a preset temperature difference level and controlling the operation of the air conditioning and ventilation system according to the temperature difference level comprises:

[0017] Determining whether the temperature difference belongs to the first temperature difference level, the second temperature difference level, or the third temperature difference level;

[0018] If the temperature difference belongs to the first temperature difference level, the air conditioner performs temperature adjustment;

[0019] If the temperature difference belongs to the second temperature difference level, the ventilation system will adjust the temperature;

[0025] Based on the first temperature difference level, the compressor frequency, the external fan speed, the internal fan speed and the exhaust temperature of the air conditioner are adjusted.

[0026] As a further solution of the present invention: if the temperature difference belongs to the third temperature difference level, the step of simultaneously adjusting the temperature of the ventilation system and the air conditioner includes:

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] Embodiment 1: Figure 1 The flowchart of the coordinated control method of the air conditioning and ventilation system operation of a data center is as follows. In an embodiment of the present invention, a coordinated control method of the air conditioning and ventilation system operation of a data center is provided, and the method includes:

[0037] Obtain the real-time indoor temperature of the data center, compare the real-time indoor temperature with the comfortable temperature of the data center, and determine whether temperature adjustment is needed;

[0038] The equipment has a certain temperature due to internal losses. If the ambient temperature is too high or the air flow is poor, the heat of the equipment cannot be dissipated in time, which will cause the equipment to trip due to overheating or even burn out. In order to ensure that various equipment in the data center can work normally, the temperature of the data center needs to be controlled within an appropriate temperature range. This temperature range is the comfortable temperature of the data center. At this time, it is necessary to monitor the indoor temperature of the data center to determine whether the indoor temperature falls within this temperature range. If the indoor temperature falls within this temperature range, the indoor temperature at this time is suitable and no temperature adjustment is required. If the indoor temperature does not fall within this temperature range, the indoor temperature at this time cannot ensure the normal operation of the equipment and the indoor temperature needs to be adjusted.

[0039] When it is determined that temperature adjustment is required, the real-time outdoor temperature is obtained to obtain the temperature difference between the real-time indoor and outdoor temperatures;

[0040] When the indoor temperature needs to be adjusted, the speed of temperature adjustment is determined based on the indoor and outdoor temperatures, so that the indoor temperature can be quickly adjusted to a comfortable temperature for the data center.

[0041] Determine whether the temperature difference belongs to a preset temperature difference level, and control the operation of the air conditioning and ventilation system according to the temperature difference level.

[0042] Different temperature differences correspond to different temperature adjustment speeds. A large temperature difference requires a larger temperature adjustment speed, while a small temperature difference can have a smaller temperature adjustment speed. A small temperature adjustment speed only requires the mobilization of a separate air conditioner or ventilation system, while a large temperature adjustment speed requires the air conditioner and ventilation system to work simultaneously, so as to quickly adjust the indoor temperature to a comfortable temperature in the data center.

[0043] The data center air conditioning and ventilation system operation coordinated control method also includes:

[0044] Obtain the real-time humidity of the data center, compare the real-time humidity with the specified humidity, and adjust the humidity if the real-time humidity is not within the specified humidity range.

[0045] Humidity also has an impact on the normal operation of equipment. Humid air is conducive to the growth of mold, which contains a lot of water, which will greatly reduce the insulation performance of the equipment. For some porous insulating materials, the roots of mold can penetrate deep into the material, causing insulation breakdown. The acidic substances secreted by mold during metabolism interact with the insulation, causing the insulation performance of the equipment to decline; humid air causes the conductive metal, magnetic silicon steel sheet and metal casing in the power equipment to rust, which will reduce the performance and service life of the equipment and even cause electrical failures. Therefore, the humidity also needs to be kept within a certain range to ensure the normal operation of the equipment in the data center. This humidity range is the specified humidity. When the indoor humidity is not within the specified humidity range, the humidity needs to be adjusted to the specified humidity.

[0046] Furthermore, the step of obtaining the real-time humidity of the data center, comparing the real-time humidity with the specified humidity, and adjusting the humidity if the real-time humidity is not within the specified humidity range includes:

[0047] Get the real-time humidity and compare it with the specified humidity;

[0048] Only by knowing the difference between the indoor humidity and the specified humidity can we determine how fast the humidity needs to be adjusted, so it is necessary to detect the real-time humidity.

[0049] If the real-time humidity is greater than the specified humidity, the air conditioner turns on the "dehumidification mode";

[0050] The specified humidity is a humidity range, with a maximum humidity and a minimum humidity. It is not appropriate to exceed the maximum humidity or be less than the minimum humidity. When the real-time humidity is greater than the maximum humidity, it indicates that the moisture content in the air is too high, which is not conducive to the normal operation of the equipment, and the moisture content in the air needs to be reduced. The air conditioner has a dehumidification function. At this time, the fan of the internal fan runs very slowly. This is to facilitate the condensation of water vapor in the air into liquid. Specifically: the temperature of the humid air will drop significantly after passing through the air conditioner evaporator, and the air humidity is in a supersaturated state. The excess water vapor is precipitated in the form of condensed water and condensed on the fins of the evaporator, so that the effect of reducing the air humidity can be achieved.

[0051] If the real-time humidity is lower than the specified humidity, the air conditioner turns on the "humidification mode".

[0052] When the real-time humidity is lower than the minimum humidity, it indicates that the moisture content in the air is too low. An overly dry indoor environment can easily cause the heat generated by the equipment to not be dissipated, which in turn causes the equipment to have reduced working efficiency or even malfunction. At this time, the indoor humidity needs to be increased. The "humidification mode" of the air conditioner simply increases the humidity in the room without lowering the indoor temperature. The air conditioner will continuously circulate and humidify the indoor air, thereby achieving the effect of increasing the air humidity.

[0053] Figure 2 The second sub-flow chart of the coordinated control method for the operation of the air conditioning and ventilation system of the data center, wherein when it is determined that temperature adjustment is required, the steps of obtaining the real-time outdoor temperature and obtaining the temperature difference between the real-time indoor and outdoor temperatures include:

[0054] When temperature adjustment is required, obtain the real-time outdoor temperature of the air outlet area;

[0055] Air conditioning and ventilation systems require indoor and outdoor air circulation for temperature adjustment. The air outlet is the channel for indoor and outdoor air circulation. The outdoor temperature at the air outlet can be used as the real-time outdoor temperature.

[0056] Subtract the real-time outdoor temperature from the real-time indoor temperature to obtain the real-time temperature difference.

[0057] The real-time temperature difference may be a positive number or a negative number. A positive number means that the outdoor temperature at this time is higher than the indoor temperature, and a negative number means that the outdoor temperature at this time is lower than the indoor temperature. In both cases, the working mode and working parameters of the air conditioning and ventilation systems are different. The working mode and working parameters of the air conditioning and ventilation systems can be adjusted according to the preset rules.

[0058] Figure 3 The third sub-flow chart of the coordinated control method for the operation of the air conditioning and ventilation system of the data center is as follows: the step of determining that the temperature difference belongs to a preset temperature difference level, and controlling the operation of the air conditioning and ventilation system according to the temperature difference level includes:

[0059] Determining whether the temperature difference belongs to the first temperature difference level, the second temperature difference level, or the third temperature difference level;

[0060] Different temperature differences indicate the distance between the indoor temperature and the comfortable temperature of the data center. The first temperature difference level indicates that the distance between the indoor temperature and the comfortable temperature of the data center is small, the second temperature difference level indicates that the distance between the indoor temperature and the comfortable temperature of the data center is large, and the third temperature difference level indicates that the distance between the indoor temperature and the comfortable temperature of the data center is large. In order to quickly adjust the indoor temperature to the comfortable temperature of the data center, the temperature adjustment rate is different. Different temperature adjustment rates correspond to different working modes and working parameters of the air conditioning and ventilation systems.

[0061] If the temperature difference belongs to the first temperature difference level, the air conditioner performs temperature adjustment;

[0062] When the difference between the indoor temperature and the comfortable temperature of the data center is small, the air conditioner alone can meet the required temperature adjustment rate, thereby quickly adjusting the indoor temperature to the comfortable temperature of the data center.

[0063] If the temperature difference belongs to the second temperature difference level, the ventilation system performs temperature adjustment.

[0064] When the indoor temperature is far from the comfortable temperature of the data center, the ventilation system alone can meet the required temperature adjustment rate, thereby quickly adjusting the indoor temperature to the comfortable temperature of the data center.

[0065] If the temperature difference belongs to the third temperature difference level, the ventilation system and air conditioning will adjust the temperature at the same time.

[0066] When the indoor temperature is far from the comfortable temperature of the data center, the ventilation system and air conditioning need to work together to meet the required temperature adjustment rate, so as to quickly adjust the indoor temperature to the comfortable temperature of the data center.

[0067] If the temperature difference belongs to the first temperature difference level, the step of the air conditioner performing temperature adjustment includes:

[0068] Based on the first temperature difference level, the compressor frequency, the external fan speed, the internal fan speed and the exhaust temperature of the air conditioner are adjusted.

[0069] The first temperature difference level only requires the air conditioner to work alone to meet the required temperature adjustment rate. The smaller the air conditioner compressor frequency, the smaller the external fan speed and the internal fan speed, and the smaller the temperature difference between the exhaust temperature and the indoor temperature, the smaller the temperature adjustment rate and the longer it takes to reach a comfortable temperature in the data center.

[0070] refer to Figure 4 If the temperature difference belongs to the third temperature difference level, the steps of simultaneously adjusting the temperature of the ventilation system and the air conditioner include:

[0071] Based on the third temperature difference level, the compressor frequency, the external fan speed, the internal fan speed and the exhaust temperature of the air conditioner are adjusted;

[0072] The third temperature difference level requires the ventilation system and air conditioning to work together to meet the required temperature adjustment rate. At this time, the air conditioner's compressor frequency, outdoor fan speed, indoor fan speed, and the temperature difference between the exhaust temperature and the indoor temperature jointly determine the air conditioner's temperature adjustment rate.

[0073] Based on the third temperature difference level, the air valve angle, supply fan speed and exhaust fan speed of the ventilation system are adjusted.

[0074] At this time, the air valve angle, supply fan speed and exhaust fan speed jointly determine the rate at which the ventilation system adjusts the temperature. The larger the air valve angle and the faster the supply fan speed and exhaust fan speed, the faster the ventilation system adjusts the temperature and the shorter the time it takes to reach a comfortable temperature in the data center.
