The specific embodiment
The air-conditioning of take in the embodiment of the present invention in the machine room of base station describes as example, it should be noted that, the present invention is not limited to base station machine room, and the present invention goes for any space environment that needs temperature to regulate and control, as the machine room of resident room or miscellaneous equipment.Kind of the present invention, described temperature regulates and specifically comprises that refrigeration regulates and heating regulates, but the present invention both can be applicable to refrigeration control, also can be applied to heating and control.
Inventor finds in real work, base station air conditioner is only relying on the autonomous controlling run of equipment itself, and adopted after the technology such as power failure self-starting, unit temperature-constant operation, the alarm of machine room high temperature, although can in the daily network operation, play important function, but still there is following shortcoming:
The air-conditioning configuration of base station is generally 2, and have have a power failure after incoming call air-conditioning autostart function, to adapt to the needs of unmanned situation temperature controlled environment, air-conditioning set temperature is 28 ℃, between its temperature controlled region, be generally 27～29 ℃, be temperature reach 29 ℃ (cooling activation temperature) start refrigeration, temperature drops to 27 ℃ (refrigeration stops temperature) and stops.
Because two air-conditionings in machine room are installed on zones of different, there is separately independently warming probe, the probe sampling of two air-conditionings to temperature can different (in actual environment, generally having the difference of 1 ℃ of left and right).And every temperature work that air-conditioning arrives according to the probe sampling of this air-conditioning, therefore sample temperature first reaches the air-conditioning of 29 ℃ and will preferentially start, and supposes that it is primary air-conditioning, starts after reaching 29 ℃ after sample temperature, suppose that it is standby air-conditioning, this mode problem mainly contains:
For primary air-conditioning: generally, after air-conditioning is installed, its position is changeless, therefore the sample temperature of primary air-conditioning first reaches the situation meeting long-term existence of 29 ℃, its long-term preferential consequence that starts operation is air conditioner refrigerating hydraulic performance decline, refrigeration performance declines and to cause again freezing the increase of duration, has further aggravated even " in spite of illness " operation of fatigue of primary air-conditioning, and power consumption also significantly increases thereupon.Especially, when the refrigeration performance of primary air-conditioning drops to cannot meet base station thermal balance needs time, standby air-conditioning can put into operation simultaneously, now just form the situation that the power consumption of 2 air-conditionings but only has standby air-conditioning to work, power consumption is more surprising, and this situation is comparatively outstanding in the base station of moving more than 2 years.
For standby air-conditioning: the in the situation that thermic load only need to starting primary air-conditioning in machine room, affected by temperature fluctuation, the probe of standby air-conditioning may detect 29 ℃, can trigger startup.This situation all exists in various degree in all base stations.The probability of its false triggering depends on the deviation size of 2 air-conditioning sample temperatures, and deviation is less, and the situation of false triggering is more remarkable.
Inventor is also further discovery in real work, and the operation of controlling two air-conditionings by time in turn pattern also has certain shortcoming.Time in turn pattern is controlled 2 air-conditionings by locomotive rotation controller, and its operation principle is that within the time setting (being generally 30 days or shorter), 2 air-conditionings are switched in timing, in rotational cycle, only have 1 air-conditioning at work, this air-conditioning autonomous operation.Meanwhile, too high for preventing computer room temperature, the warming probe being carried by time in turn controller judges whether sample temperature surpasses 30 ℃, when surpassing 30 ℃, by time in turn controller, further starts the 2nd air-conditioning.
The advantage of this mode is the operations of " having holidays by turns " of 2 air-conditionings, has also avoided standby air-conditioning false triggering simultaneously, but still the heat pump performance that cannot solve in the rotation phase declines, and causes the long playing problem of air-conditioning, and energy consumption is still higher.
Based on above discovery, inventor utilizes local resource and technical advantage, explore air conditioning applications in the adaptive improvement method of base station refrigeration, and further proposed air-conditioning lifecycle management pattern, has reached the object of energy efficiency, environmental protection.Below with reference to accompanying drawing, by specific embodiment, the present invention is described in detail.
The control method of the operation of air conditioner described in the embodiment of the present invention, the operation that is applied to be arranged at least two air-conditionings in machine room is controlled, and is also provided with the air-conditioner intelligent controller being connected with every air-conditioning in described machine room.Please refer to Fig. 1, control method comprises the following steps described in the present embodiment:
Step 11, the temperature that the described air-conditioner intelligent controller of usining detects, as the environment temperature of described machine room, is controlled respectively every air-conditioning, under between the first temperature controlled region, described machine room is carried out to temperature adjusting test, obtains the temperature adjusting function parameter of every air-conditioning.
Here, according to this each air-conditioning is carried out respectively to temperature and regulate test, for guaranteeing the unification of testing standard, the environment temperature that the temperature that all air-conditionings are used air-conditioner intelligent controller to detect is reference, the temperature of controlling air-conditioning according to this temperature regulates; And all air-conditionings all carry out temperature adjusting test under between identical temperature controlled region.In the present embodiment, the warming of described air-conditioner intelligent controller probe, is preferably mounted in the position equating with each air-conditioning distance.
Here, the method for testing of concrete temperature adjusting function has multiple.For example, under identical temperature control interval, every air-conditioning regulates start-up temperature to start temperature from temperature and regulates, and temperature is adjusted to temperature and regulates and stop temperature always, tests every required temperature of air-conditioning and regulates duration.In this case, temperature adjusting function parameter is from uniform temp, to regulate start-up temperature to start refrigeration to regulate and stop the required temperature adjusting duration of temperature to identical temperature.Such as, take and freeze as example, two air-conditionings are realized respectively computer room temperature from the refrigeration of 29 ℃ to 27 ℃, and temperature regulates the longer air-conditioning of duration, and its temperature adjusting function is poor; Otherwise temperature regulates the shorter air-conditioning of duration, its temperature adjusting function is better.
Again for example, every air-conditioning regulates start-up temperature to start temperature adjusting from temperature, regulates the environment temperature of testing machine room after one period of identical scheduled time in temperature.In this case, temperature adjusting function parameter is the environment temperature of machine room from uniform temp adjusting start-up temperature starts temperature adjusting same time.Such as, take and freeze as example, two air-conditionings carry out temperature adjusting (refrigeration) since 29 ℃ respectively, in refrigeration after half an hour, the corresponding air-conditioning of lower building environment temperature, its temperature adjusting function is better, otherwise poor.
Step 12 according to described temperature adjusting function parameter, is selected the best air-conditioning of temperature adjusting function and is set to primary air-conditioning from described at least two air-conditionings.
In actual environment, may exist the temperature adjusting function of two above air-conditionings to be locked in a tie for first.For example, in only comprising the machine room of two air-conditionings, these two air-conditioner temperature adjusting function parameters are identical, and now the best air-conditioning of temperature adjusting function has two.In this case, above-mentioned steps 12 specifically comprises:
Judge in two best above air-conditionings of temperature adjusting function, whether have current the first air-conditioning that has been set to primary air-conditioning;
When there is described the first air-conditioning, from best more than two air-conditioning of described temperature adjusting function, select described the first air-conditioning the second air-conditioning in addition, primary air-conditioning is updated to described the second air-conditioning;
When not there is not described the first air-conditioning, from best more than two air-conditioning of described temperature adjusting function, select arbitrarily an air-conditioning and be set to primary air-conditioning.
By above processing, during the air-conditioning that is locked in a tie for first in the temperature adjusting function existing more than two, can realize the rotation of primary air-conditioning, avoid for a long time using an air-conditioning as primary air-conditioning the work long-term tired out of minimizing air-conditioning.In actual environment, between the forward air-conditioning of temperature adjusting function, possible temperature adjusting function parameter difference is very little, for example be less than certain predetermined threshold, now can think that the temperature adjusting function of these air-conditionings is identical, be locked in a tie for first, thereby increase the probability that primary air-conditioning wheel changes jobs.
Step 13, only starts described primary air-conditioning, and usings temperature that described air-conditioner intelligent controller detects as the environment temperature of described machine room, controls described primary air-conditioning, under between the second default temperature controlled region, described machine room is carried out to temperature adjusting.
Between the first above-mentioned temperature controlled region and can be identical between the second temperature controlled region, also can be different.
Can find out, in above step, any air-conditioner temperature in machine room is all to take temperature that air-conditioner intelligent controller detects as with reference to carrying out work while regulating, all air-conditionings have unified environment temperature, rather than separately self-dependent warming probe sampling to temperature carry out work, make the result of temperature adjusting function test more reliable.The present embodiment is by above step, by carry out the test of temperature adjusting function in concrete building environment, from all air-conditionings of machine room, select the best air-conditioning of temperature adjusting function, only utilize this air-conditioning to carry out temperature adjusting to machine room, thereby avoided the temperature that the poor air-conditioning of serviceability temperature adjusting function causes to regulate the problem that efficiency is low, energy consumption is high.
Above step 11～13 can periodically be carried out, for example monthly/carry out once weekly, thereby periodically test, choose the best air-conditioning of performance as primary air-conditioning, and the wheel of realizing primary air-conditioning when there is the air-conditioning that more than two temperature adjusting function is locked in a tie for first changes jobs.
Select primary air-conditioning; and only rely on primary air-conditioning to carry out temperature while regulating to machine room; the present embodiment can also further be detected in real time the thermoregulator work duration of single of described primary air-conditioning and be shut down duration by described air-conditioner intelligent controller; and when the ratio of described work duration and described shutdown duration is greater than predetermined threshold; other air-conditioning beyond described primary air-conditioning described in startup at least two air-conditionings participates in the temperature of described machine room to regulate, thereby the intelligent linkage of realizing between air-conditioning is controlled.
For example, by the single refrigeration duration of the primary air-conditioning of air-conditioner intelligent controller Real-Time Monitoring with shut down duration, calculate this proportionate relationship, when its refrigeration duration is greater than while shutting down 3 times of duration, enable the standby air-conditioning outside primary air-conditioning.Due to adding of standby air-conditioning, the refrigerating capacity of machine room is increased sharply, computer room temperature is quickly fallen to refrigeration and is stopped temperature (27 ℃), thus primary, spare air-conditioning can stop fast.In this case, power consumption is basic identical, but long-play while having avoided primary air-conditioning separate refrigeration, and the environment temperature of machine room is also more reasonable.
The present embodiment can also be according to single work duration and master pattern, and whether real-time judge heat pump performance declines, and prevents that air-conditioning is in " weak " refrigeration/heating state for a long time; Corresponding service data and warning information become effective support of configuration, replacing and the optimization of air conditioner in machine room.
Further, the present embodiment can also, according to the situation of machine room thermic load, to dynamically adjusting between temperature controlled region, rationally to utilize air-conditioning work characteristic, improve refrigerating efficiency.For example, be subject to season, round the clock, the impact of the factor such as weather, machine room its heat within some period can increase suddenly.For example, when summer, to be subject to Exposure to Sunlight to affect its heat high for machine room, and when temperature is lower in the winter time, computer room temperature is also corresponding lower; And machine room heat by day can be greater than the heat in night, etc.Therefore, in the present embodiment, further according to machine room environment of living in, preset high heat load period or low heat loads period, the heat in the wherein said high heat load period in described machine room is greater than the heat in described machine room in the described low heat loads period.Then, by described air-conditioner intelligent controller, judge whether current time belongs to default high heat load period or the low heat loads period: in current time, belong to described high heat load during the period, the refrigeration in improving between described the second temperature controlled region stops temperature; In current time, belong to described low heat loads during the period, the cooling activation temperature in improving between described the second temperature controlled region.
Adopted after above-mentioned processing, the present embodiment is at high load capacity during the period, when the heat of machine room increases suddenly (as Exposure to Sunlight, high temperature etc.) and causes air-conditioning single refrigeration duration longer, keeping under the temperature-resistant prerequisite of cooling activation, the refrigeration that system improves to a certain degree automatically stops the single refrigeration duration that temperature reduces air-conditioning.Both avoid air-conditioning long-play, also saved certain electric energy, and at underload during the period, easily occur that (opening " 6 " characteristic refers to after starting of air conditioner refrigerating state because air-conditioning is opened " 6 " characteristic, a period of time is at least moved in capital, as 6 minutes, its objective is and make air conditioning chamber's internal and external pressure balance, preventing that " liquid hammer " causes compressor damage) cold that causes is more than needed, keeping refrigeration to stop under temperature-resistant prerequisite, suitably improving the upper limit is cooling activation temperature, the benefit of doing is like this to take full advantage of air-conditioning to open " 6 " characteristic, in the situation that be equally all the refrigeration duration of 6 minutes, the raising of upper limit cooling activation temperature, can greatly improve the shutdown duration of air-conditioning, effectively saved the power consumption of air-conditioning.Although mean temperature is a little more than desired temperature, owing to being the low temperature period, temperature controlled environment is also safer.Like this, the present embodiment can change according to thermic load, between temperature controlled region, can automatically between 0.5-3 ℃, dynamically arrange, when thermic load is high, automatically shorten between temperature controlled region, when thermic load is low, expand between temperature controlled region, realize the accurate control of various types of air-conditionings under difference configuration, Different climate condition, when guaranteeing that air-conditioning is in best duty, further realized energy-efficient under middle low heat loads condition.
In the present embodiment, can also utilize container to carry out air conditioner in machine room condensation water collection, when high temperature, by air-conditioner intelligent controller, control magnetic valve and carry out condensate water atomizing with spraying motor, with cooling off-premises station fin.
Inventor also finds, base station generally adopts unattended operational mode at present, except finding air-condition faults by patrolling and examining, just can arrive on-the-spot investigation problem after only having base station to produce high temperature alarm, belongs to passive extensive style maintenance management.And air-conditioning is the equipment that integrates machinery, electronics, freezes, in the long-term running in base station, inevitably there is the phenomenons such as wearing and tearing, device aging, the leakage of snow kind, so its refrigeration power to decline be the process of a gradual change.If can not recognize in time these information and make investigation, just there will be identical input power, refrigerating capacity is but significantly shunk, not only computer room temperature can raise, and cause that energy consumption increases, air-conditioning shortens service life.Therefore, improving on the basis of operation of air conditioner control mode, also need to, further combined with active heat pump performance management means, could fundamentally solve the situation of air conditioning energy consumption waste.
For this reason, the present embodiment is realized the air conditioner in machine room of autonomous operation is carried out to the management of network platform formula in Internet of Things mode, by GPRS network, realizes the real-time network management of " people is to air-conditioning ".Concrete, please refer to Fig. 2, the present embodiment further arranges GPRS communication module in the machine room of base station, air-conditioner intelligent controller in machine room is connected with GPRS network by this GPRS communication module, thereby be connected with the control terminal of far-end, thereby the service data of the air-conditioning that air-conditioner intelligent controller can send to control terminal, and receive the control instruction that described control terminal sends, and carry out corresponding operation according to described control instruction.For example, in step 11, obtain after the temperature adjusting function parameter of air-conditioning, if judge the temperature adjusting function of certain air-conditioning, do not met predetermined requirement, the panel leds that now can pass through provides indication, can also pass through GPRS communication module, via GPRS network, to control terminal, send alarm prompt.Air-conditioner intelligent controller can also send to control terminal the running state data such as machine room Current Temperatures, air-conditioning power consumption.Meanwhile, control terminal also can be by GPRS network to air-conditioner intelligent controller sending controling instruction, in order to revise between temperature controlled region or primary air-conditioning etc. is set, thereby realizes the real-time network management of " people is to air-conditioning ".
Concrete, control terminal can be achieved as follows function:
1) intuitively present operation of air conditioner curve, start the information such as frequency, the alarm frequency, in time, accurately grasp the operation conditions of the whole network air-conditioning;
2) by Long-distance Control, realize the setting of air-conditioning parameter and closing of fault air-conditioning;
3) coordinate digital electric meter, realize air-conditioning electric quantity monitoring and management;
4) instruct planning, construction, operation, the optimization of the whole network air-conditioning.
Adopt after the control terminal shown in Fig. 2, the present embodiment can be abandoned air-conditioning in prior art " independent unit autonomous operation " pattern, has solved fault and cannot estimate, keep in repair the extensive management defects such as hysteresis, operating condition is not clear, operating cost is unclear.The present embodiment by dynamically adjusting between the temperature controlled region of each air-conditioning, air-conditioning switch Long-distance Control, guarantee the dynamic equilibrium of refrigerating capacity and thermic load, make air-conditioning always work in " the best " state, reach energy-conservation object; Initiatively the management of preventive heat pump performance comprises: service data management, air-condition faults are reported to the police, managing electric quantity, makes it to find in advance the hidden failure of air-conditioning, makes air-conditioning always work in " health " state, reaches energy-conservation object; Add running background data are analysed in depth, realize the General Promotion of heat pump performance.
Adopted after the control method of operation of air conditioner of the present embodiment, through the test data to real base station, comprehensive high and low temperature test result in season, finds that average power saving rate should be more than 15%, can obtain good energy-saving effect, realize air conditioning high efficiency rate and run cheaply.
(2) low temperature season power saving rate is high, but amount of electricity saving is less, and high temperature season is contrary, and main cause is that low temperature season power consumption itself is just fewer, and high temperature season is higher.
(3) power savings is obvious, and the size of power saving rate depends on the pattern of former operation of air conditioner, is to adopt two air-conditionings to move or separate unit rotation pattern simultaneously.In fact, when machine room thermic load is large, air-conditioning unreasonable allocation, outdoor environment temperature be when higher, often adopts two operational modes simultaneously, this is that a lot of city company adopts.At this moment power saving rate is more obvious.
