In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.

All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs unless specifically defined otherwise. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.

Fig. 1 shows a schematic diagram of a room air conditioning system of a room using a hot aisle enclosure technique and an indirect natural cooling air conditioner 1.

The indirect natural cooling air conditioner 1 mainly includes: the air heat exchanger 101, the outdoor fan 102 and the indoor fan 103 are used for realizing heat exchange between air with higher indoor temperature and air with lower outdoor temperature and cooling the indoor air, so that the data center machine room is cooled. Wherein, outdoor air can enter the air heat exchanger 101 through the outdoor cold air inlet valve 104 for heat exchange. Because the cooling process of the data center does not use a mechanical refrigeration technology with higher energy consumption, the cooling of the indoor air of the machine room is realized only by adopting an indoor and outdoor air heat exchange method, namely, the cooling of the indoor air is realized naturally and indirectly by utilizing the air with lower outdoor temperature through a heat exchanger, so the cooling process is called indirect natural cooling; in the air conditioning industry, the air conditioning industry is also called free cooling, because in the process of natural heat exchange, the consumed energy mainly takes the energy consumption of a fan as the main energy consumption, and the energy consumption is low.

With continued reference to fig. 1, the space within the room is divided into two sections, with the higher temperature called the hot aisle and the lower temperature called the cold aisle. The space between the two rows of servers is closed, and cool air sent from the air conditioner 1 enters the closed space and then flows out from the server cabinet 2, which is called as cold passage closure. If the direction of the airflow is opposite, and the cold air sent by the air conditioner 1 enters the closed space (and then returns to the air conditioner 1) after passing through the server cabinet 2 from the outside, the airflow organization is called as hot channel closure.

By adopting the cold channel sealing and hot channel sealing technologies, good air flow organization of the air conditioning system can be realized, so that the energy efficiency of the air conditioning system is improved. After the cold channel sealing or hot channel sealing technology is adopted, the temperature of indoor air returning to the air conditioner 1 (namely, the temperature of the hot channel) can reach about 35 ℃, the difference value between the temperature of inlet air at the indoor side of the air conditioner 1 and the temperature of outdoor air is improved, and compared with a machine room which does not adopt the cold channel sealing or hot channel sealing technology, the energy saving performance is obviously improved.

Since the power consumption of the fan of the air conditioner 1 is proportional to the rotational speed of the fan to the power of 3, the rotational speed of the fan is reduced as much as possible. The control devices of the natural cooling air conditioner 1 each include this energy saving function, but the rotational speed of the fan is determined and calculated only based on the difference between the return air temperature of itself and the outdoor temperature, and the energy saving control logic cannot be optimized from the overall perspective of the machine room and the air conditioning system.

If the layout of the machine room structure and the air returning structure is poor, air distribution is uneven or cannot be distributed according to needs, and the outlet air temperature of each server cabinet 2 is inconsistent.

Because there may be many air conditioners 1 serving a data center room, and there are multiple air supply outlets and air return inlets, the situation that the air supply amount of the air conditioners delivered to each position of the room is inconsistent or the air cannot be supplied on time is inevitable, and in order to ensure that the air outlet of each server cabinet 2 is uniform or meet the design requirement of the server, generally, the air supply temperature of all the air conditioners 1 has to be reduced to meet the air outlet temperature control requirement of the server or the cabinet. This cooling approach undoubtedly increases the energy cost of cooling.

The application provides an energy-saving control method for an air conditioner, firstly, temperature information of a plurality of preset point positions in a machine room is obtained, space temperature image information in the machine room is determined according to the temperature information and a gradual change algorithm, a superheat area in the machine room is determined according to the space temperature image information, the air conditioner 1 corresponding to the superheat area is started, and the superheat area is cooled.

Fig. 2 shows a flowchart of an energy-saving control method of an air conditioner according to an embodiment of the present application. The method is applied to electronic equipment in an air-conditioning cooling system, the system also comprises a temperature sensor and an air conditioner, and the method comprises the following steps:

and S100, acquiring temperature information and position information of a plurality of preset point positions in the designated space.

In the embodiment of the application, the designated space may be a data center room space, and in order to accurately determine the superheat area in the room, a space temperature field of the room needs to be established instead of a planar temperature field. Therefore, the preset point locations can be in the vertical direction, the machine room is divided into multiple layers of spaces, a plurality of preset point locations are arranged on each layer, the preset point locations on each layer can be uniformly distributed, and the setting density of the preset point locations close to the server can be increased according to the position of the server.

Because the temperature field obtained by CFD simulation in the design stage has a large difference from the actual operating temperature field, and is limited by the amount of calculation and the calculation cost, the CFD simulation in the design stage cannot be sufficiently performed, and thus it is difficult to apply the CFD calculation result in the design stage to the actually operating machine room. For example: in the design stage, it is difficult to simulate the situations that servers are not installed in some cabinets and more servers are installed in some cabinets; it is also difficult to simulate which cabinets have less calculation amount at ordinary times, but the calculation amount is greatly increased on some special dates.

Therefore, in order to accurately grasp the actual situation of the heat productivity of the machine room, an actual temperature field measuring device needs to be installed at a preset point position, the temperature field measuring device can be a temperature sensor, in order to guarantee the accuracy of a space temperature field, the temperature sensors need to be arranged on planes of the machine room at different heights, and each plane needs to be provided with enough sensors.

At present, the cost of conventional temperature sensors is not high, and the difficulty in installing a large number of temperature sensors in a machine room is not high, however, the difficulty in sending the temperature data and the position data of the temperature sensors to a data acquisition unit is certain.

The conventional method is to connect the signal line of the temperature sensor into the temperature data collector and manually input the position information of the temperature sensor into the data collector, which increases a lot of installation workload, and after the position of the temperature sensor changes, the position data needs to be input again, which further increases the workload and is easy to make mistakes. When the number of the installed temperature sensors is large, the workload of installing the lines is large, and the difficulty of wiring is increased.

Therefore, the problem that wiring is complex or difficult to achieve is solved in a wireless transmission mode. The method for binding the temperature sensor and the position sensor is adopted to realize automatic synchronous transmission of temperature and position. The bound sensor sends a position signal while sending a temperature signal, so that the temperature data collector can automatically establish the spatial position information of each temperature, and a spatial temperature lattice which accords with an actual installation position is automatically established in a computer.

By adopting the wireless transmission mode, even if the position of the bound sensor is changed as required, the temperature data collector can update the position information of the sensor immediately, and the workload is reduced.

And S200, determining the space temperature image information of the designated space according to the temperature information, the position information and a preset gradient algorithm.

The gradual change algorithm specifically may be a form of dividing the machine room into a plurality of spatial grids, the width of each spatial grid is far smaller than the distance between two preset point locations, a reference point is specified at the same position of each spatial grid, a temperature difference between every two reference points is calculated according to a temperature difference between the two preset point locations and the number of the reference points between the two preset point locations, and then the temperature information of each reference point is calculated by taking the temperature of the preset point location as a reference. And obtaining a smooth temperature curve formed between any two preset point positions, and further obtaining space temperature image information.

And S300, determining a superheat region in the appointed space according to the space temperature image information and the hot region algorithm model.

After the space temperature image information is determined, in order to further improve the heat efficiency, the temperature of the overheated area in the machine room can be preferentially reduced. The specific way to determine the superheat region may be to use the following hot zone algorithm model:

step S301, dividing the area in the machine room into a plurality of cubic areas, and calculating the average temperature of each cubic area;

s302, arranging the average temperature of each cubic area in a descending order according to the descending order, and screening out cubic areas with the average temperature ranking 50% higher;

step S303, dividing the screened cube region into a plurality of sub-cube regions, and calculating the average temperature of each sub-cube region;

s304, screening out a subcube region with the highest average temperature in each cube region;

and S305, dividing the subcube area into secondary subcube areas, screening out the secondary subcube area with the highest temperature, dividing the secondary subcube area until the volume of the subcube area obtained by division is smaller than a preset volume, and determining that the subcube area obtained by final screening is a hot spot, wherein the cubic area to which the hot spot belongs is a superheated area.

The manner of calculating the average temperature of the cubic area may be: and acquiring the temperature information and the number of the reference points of the cubic space, and performing average calculation according to the temperature information and the number of the reference points of each reference point to obtain the average temperature of the cubic area.

In a specific example, after the space temperature image information is determined, a cubic space is established according to the maximum sizes of the length, the width and the height of the cabinet in the machine room, and the machine room is divided into a plurality of cubic areas consisting of a series of cubes which are continuously arranged by utilizing the cubic space; arranging the average temperature of each cubic area in a descending order according to the descending order, and screening out cubic areas with the average temperature of 50% of the top rank; halving the side length of the screened cubes, dividing the cubes with higher temperature by using the reduced cube region, and then calculating the average temperature of the superheat region with halved side length; and selecting the cubes with higher average temperature in the cubes with the halved side length for calculation, and after the cube region with the halved side length is processed for 2 to 5 times, reducing the side length of the cubes to be below 300-500 mm without reducing the size of the cubes. At this time, the small cube with the higher temperature obtained by calculation is considered as a hot spot. The hot spot with the highest temperature is the hot spot needing to be eliminated preferentially, and the width of the hot spot is larger than the temperature of the space grid.

The area established by taking the hot spot as the center and taking the average value of the three sizes of the length, the width and the height of the cabinet as the side length is the overheating area needing to be eliminated.

And S400, when the temperature difference between the average temperature of the overheating area and the preset control temperature is higher than the preset difference, determining the air conditioner 1 corresponding to the overheating area according to the corresponding relation between the air conditioner 1 and different areas in the designated space, and increasing the operating power of the air conditioner 1 corresponding to the overheating area.

In the embodiment of the application, after the superheat area is determined, the temperature difference between the average temperature of the superheat area to be judged and the preset control temperature is firstly determined, when the temperature difference is lower than the preset difference, all air conditioners 1 corresponding to the superheat area are started, and the air conditioners 1 are made to operate at the standard power. When the temperature difference is higher than the preset difference, the operating power of the part of the air conditioner 1 corresponding to the superheat region is increased to improve the cooling efficiency. The preset difference may be set by a worker based on experience, and the correspondence relationship between the air conditioner 1 and the area in the designated space may be stored in the electronic device in advance based on the setting of the air conditioner in the room.

In a conventional data center room, a backup air conditioner 1 is generally configured in a matching installed air conditioner 1, and depending on the grade and design objective of the data center, there are usually 1 to N backup air conditioners 1 in the room, and these air conditioners 1 are generally in a cold backup mode, that is: only when one of the air conditioners 1 fails, one of the backup air conditioners 1 is started to operate. Since the power consumption of the fan is proportional to the rotation speed of the fan to the power of 3, the rotation speed of the fan should be reduced as much as possible to significantly reduce the power consumption of the fan.

Since the natural cooling capacity of the air conditioner 1 is in direct proportion to the air output of the air conditioner 1, and the air output of the air conditioner 1 is in direct proportion to the rotational speed of the fan, the present embodiment takes the total air output as a, the number of the air conditioners 1 turned on as n, and the total power of the air conditioner 1 as Q.

Then

It can be known that the larger n is, the smaller the total power Q of the air conditioner 1 is, so that the present application abandons the conventional cold standby mode of the air conditioner 1 and starts all the air conditioners 1 corresponding to the superheat area to achieve a better energy saving effect.

In the embodiment of the present application, the air conditioner 1 may be matched with the superheat area in a manner that the air conditioner 1 located in the cubic area is divided into the cubic areas according to the cubic areas obtained by dividing in the machine room, and after the superheat area is confirmed, the corresponding air conditioner 1 may be determined according to the superheat area.

However, since the space in the machine room is complicated, not all the overheated areas can be directly matched with the corresponding air conditioners 1, each air conditioner 1 is a cold passage for sending the air to the machine room together, and the distances from each air conditioner 1 to the overheated areas are different, so that each air conditioner 1 contributes differently to the air output of the overheated space.

If a CFD software system is installed in the system, the real-time adjustment of the air supply quantity and the refrigerating quantity of the air conditioner 1 can be realized. However, installation of CFD software requires a large initial investment, a high running cost, and a large amount of work. Therefore, the overheating area is eliminated by the sequential tasting method, so that the work of eliminating the overheating area can be effectively finished and the energy-saving effect can be obtained under the condition that CFD software is not installed.

Specifically, the air supply amount of 1 air conditioner 1 closest to the superheat space may be increased by a preset margin, and then whether the temperature of the superheat region is decreased is detected, and if the temperature of the superheat region is decreased, the air supply amount and the cooling amount are continuously increased by a certain margin until the air amount and the cooling amount reach the maximum or the temperature of the superheat region is not decreased after the air supply amount is continuously increased; conversely, if the air supply amount and the cooling amount of the air conditioner 1 are increased and the temperature of the superheat region is not decreased, it means that the influence of the air conditioner 1 on the superheat region is small, and therefore the operating state of the air conditioner 1 is restored to the standard power; acquiring the distance relation between the air conditioner 1 and the overheating area, arranging the air conditioner 1 in an ascending order according to the distance relation, and sequentially increasing the operating power of the air conditioner 1 according to the arrangement order until the state of the overheating area is eliminated or improved. The above-described increase in the operating power may be embodied as an increase in the amount of air supplied and the amount of cooling of the air conditioner 1.

The sequential trial method provided by the application can achieve the effect of the CFD system under the condition of not using the CFD technology, saves the investment cost of the CFD system, and is a better method for cooling the overheated area of the machine room.

In another embodiment, because hardware such as server layout, air conditioner air supply position and air conditioning equipment in the machine room are already set, and the situation that all overheating areas cannot be eliminated only by the operation and cooling of the air conditioner 1 inevitably exists, the application also provides an air conditioner 1 robot consisting of an intelligent mobile robot and a mobile air conditioner, wherein the mobile air conditioner 1 is installed on the intelligent robot and is in signal connection and power supply connection with the intelligent robot; the intelligent robot is provided with a direct current power supply, and the mobile air conditioner 1 works by utilizing the direct current power supply of the intelligent robot, can send cold air to the space nearby and meets the requirement of a superheat area on large cold quantity.

When the overheating area cannot be eliminated, the intelligent robot is controlled to move to the position corresponding to the hot spot, and after the intelligent robot reaches the designated position, the mobile air conditioner 1 is controlled to be started to cool the overheating area. After the power supply is exhausted, the intelligent robot can automatically return to the charging bin for charging for the next calling. At the moment, if the overheating area is not eliminated, another intelligent robot can be randomly called to the position of the corresponding overheating area to timely reduce the temperature.
