Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing to this
The control method of compressor of air conditioner heat tape and the detailed description of the invention of device of invention illustrate.Should
Understanding, specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Control method one embodiment of the compressor of air conditioner heat tape of the present invention, as it is shown in figure 1, work as air-conditioning
When being in holding state, according to following steps, compressor heat tape is controlled:
S100, detects whether the outdoor environment temperature residing for described air-conditioning is in soaking condition, and is detected
Result.
In the present embodiment, using the conversion trend of outdoor environment temperature as topmost control parameter, this be because of
For, the rising of general outdoor environment temperature just can cause compressor hydrops, and outdoor environment temperature is in decline
Or time under conditions of constant, compressor of air conditioner does not typically have hydrops phenomenon.
For the detection of outdoor environment temperature soaking condition, can be by the temperature detector being arranged on off-premises station
Carry out, when temperature detector detects that outdoor environment temperature is more and more higher, then can be determined that current outdoor ring
Border temperature is in propradation, that is, current outdoor ambient temperature is in soaking condition.
According to the testing result of step S100, when outdoor environment temperature is in soaking condition, perform step
S200, opens the heat tape of compressor of air conditioner.
According to description above, when outdoor environment temperature is in soaking condition, easily there is hydrops in compressor
Phenomenon, therefore, in the present embodiment, when outdoor environment temperature is in and gradually rises trend, controls to open pressure
Compressor is internally heated by the heat tape of contracting machine, reduces copper two devices and the pressure reduction in compressor, from
And avoid compressor hydrops.
Described heat tape is a kind of parts being internally heated compressor, including can also be to compressor
The winding being internally heated.
According to the testing result of step S100, when outdoor environment temperature is in cooling state or steady state (no
It is in soaking condition) time, perform step S300, close heat tape.
It should be noted that step S200 is driven by the heat tape of control compressor avoid compressor
Hydrops phenomenon there is, it is ensured that the performance of compressor.And from the point of view of for energy-conserving and environment-protective, in this step
In the case of ensureing that compressor does not haves hydrops phenomenon, control compressor heat tape and close, it is thus possible to
The saving energy of limits.
Drawn by above-mentioned, the control method of the compressor of air conditioner heat tape of the present embodiment, according to judging outdoor
Ambient temperature is in ascent stage or decline stage, and when unit is standby, only ambient temperature is in rising
Heat tape or the compressor winding of just opening compressor when of stage heat.It is different from tradition skill
Art uses the mode that fixed temperature value compares.In the middle of one day, outdoor environment temperature first transition
The interval declined less than temperature, is thus greatly reduced and opens the time that compressor heat tape is opened, rise
To the effect reducing standby energy consumption.And the detection limit in the present embodiment only has outdoor environment temperature, detection limit and
Process data volume is few, and treatment effeciency is high.
Whether soaking condition is in for the judgement of the variation tendency of outdoor environment temperature, i.e. outdoor environment temperature
Detection, one-time detection can be carried out at interval of the first certain Preset Time.That is, an interval is previously set
Time (the first Preset Time), use the mode of circulation, judge an outdoor temp at interval of the first Preset Time
Whether degree is in soaking condition, and once detect that outdoor environment temperature is in soaking condition, then opens
The heat tape of compressor heats.
For example, it is assumed that the first Preset Time is 10 minutes, if then both sides all detect outdoor environment temperature continuously
Degree is soaking condition, then can control compressor heat tape and continuously open 20 minutes；And if continuous three times all
Detect that outdoor environment temperature is soaking condition, then control compressor of air conditioner heat tape and continuously open 30 minutes,
Until the temperature sensor being arranged on air-conditioner outdoor unit detects constant (the constant shape of outdoor environment temperature
State), or outdoor environment temperature is in cooling state, and the heat tape that can control compressor of air conditioner is closed,
Stop heating.
And for the detection of outdoor environment temperature, acquisition, it is possible to pass through Network Capture.Concrete, can pass through
GPRS location obtains the real-time transform situation when ground temperature from network.
For described first Preset Time, in previous embodiment, the first Preset Time set for 10 minutes, also
May be configured as 15 minutes, 20 minutes, other numerical value such as 9 minutes.It can be according in actually used, outdoor temp
The degree parameter such as sensor detection sensitivity, air-conditioning internal controller processing speed sets.
When operation of air conditioner, compressor of air conditioner electric heater to be closed.It is embodied in rate-determining steps, such as Fig. 2
Shown in, comprise the following steps:
S010, it is judged that whether air-conditioning runs；
When judging operation of air conditioner, the most directly perform step S300, close heat tape；And treat at air-conditioning
During machine state (inoperative), the heat tape of compressor of air conditioner is carried out by S100～S300 in accordance with the previously described process
Control.
Herein it should be noted that the present embodiment is given tacit consent to air-conditioning have a two states: running status and standby shape
State.Therefore, it is judged that air-conditioning is not running status, then it is assumed that be in holding state during air-conditioning.
In another embodiment, as it is shown on figure 3, before step S100, further comprising the steps of:
S011, the delivery temperature of detection compressor.
Detection to described delivery temperature, can be carried out by being arranged on the temperature sensor of exhaust outlet of compressor.
S012, it is judged that whether delivery temperature is more than or equal to preset temperature value.
Setting those skilled in the art of this preset temperature value can enter according to concrete compressor practical operation situation
Row sets, and the principle of setting is exactly, and compressor will not hydrops.That is, when exhaust outlet of compressor temperature is higher than this
During one preset temperature value, compressor does not have hydrops phenomenon and occurs.
When delivery temperature is more than or equal to preset temperature value, then performs step S300, close heat tape.
When delivery temperature is less than preset temperature value, continue executing with abovementioned steps S100, residing for detection air-conditioning
Whether outdoor environment temperature is in soaking condition.
In the present embodiment, before outdoor environment temperature is judged, first compressor exhaust temperature is entered
Row judges.Wherein, the judgement to compressor exhaust temperature is directly carried out by preset temperature value, it is judged that mode
Relatively simple, computational efficiency is high.
Concrete, when detecting the outdoor environment temperature residing for air-conditioning and whether being in soaking condition, such as Fig. 4 institute
Show, using the interval of each first Preset Time △ t as a detection cycle.Utilize the temperature on air-conditioner outdoor unit
The current outdoor ambient temperature of degree sensor detection current period is calculated as Ti (S110), and stores in caching.Again
The previous outdoor environment temperature Ti-1 in a upper circulation is transferred from air-conditioner controller.And described previous outdoor ring
Border temperature corresponding with described current outdoor ambient temperature two detection is upper the most adjacent for cycle time.
The previous outdoor environment temperature of current outdoor ambient temperature with adjacent previous cycle is compared
(S120).Current outdoor ambient temperature is more than previous outdoor environment temperature, i.e. during Ti ＞ Ti-1, it is determined that outdoor
Ambient temperature is in soaking condition.Continue executing with step S200, open the heat tape of compressor of air conditioner.When
So, current outdoor ambient temperature is less than or equal to previous outdoor environment temperature, i.e. during Ti≤Ti-1, then it is assumed that room
External environment temperature is in cooling or invariant state, then continue executing with step S300, closes heat tape, and
Again outdoor environment temperature Ti is detected after the △ t time of interval.
And as shown in Figure 4, the present embodiment also includes step S011 detecting the delivery temperature of compressor, with
And step S012 that the delivery temperature of compressor judged, and when delivery temperature is more than preset value, hold
Row closes step S300 of heat tape '.And step S300 ' identical with step S300 content and the process of execution,
Simply do not include that elapsed time △ t carries out the connection of outdoor environment temperature detection again.
And for the detection of compressor exhaust temperature, in loop control, outdoor environment temperature can carried out every time
All detect the when of degree detection, it is possible to only at compressor by the first time heat tape running to holding state
Detect during control.
Wherein in the control method of the compressor of air conditioner heat tape of an embodiment, also include detection meter
The current outdoor ambient temperature calculated carries out the step stored.Concrete, using current outdoor ambient temperature as newly
Previous outdoor environment temperature store, and delete original previous outdoor environment temperature.So, it is possible
Ensure, when the outdoor environment temperature carrying out current period converts Trend judgement, have enough comparison parameters, with
Time can reduce again the memory space taken as far as possible.
And for the detection of outdoor environment temperature, concrete, outdoor environment temperature in current period can be used
Meansigma methods is as current outdoor ambient temperature.Use outdoor environment temperature in the previous cycle adjacent with current period
The meansigma methods of degree is as previous outdoor environment temperature.
By the temperature sensor detection outdoor environment temperature being arranged on air-conditioner outdoor unit in each cycle period
Number of times can be determined according to the actual requirements.3 or 5 are detected in each detection cycle can be set
Outdoor environment temperature, and value calculating that 3 had been detected by or 5 outdoor environment temperatures are averaged.
The more dispersion that the quantity that can be generally considered as detecting is the most, test point was distributed within the detection cycle will be (as detected
Cycle temporally decile, carries out outdoor environment temperature detection at each Along ent), then the outdoor environment temperature calculated
Degree meansigma methods accuracy is the highest.But corresponding, the quantity of detection is the most, and complexity of the calculation improves the most relatively,
Treatment effeciency also can step-down relatively.
Can also use in other embodiments, at interval of described first Preset Time one outdoor environment of detection
Temperature, and the mode of the outdoor environment temperature as current period.So, treatment effeciency is of a relatively high.
But outdoor environment temperature accuracy of detection is relatively low.
It addition, after unlatching heat tape, can set after heat tape opens certain time and be automatically switched off.That is,
After the heat tape opening compressor of air conditioner in step s 200, after also including second Preset Time
Close the step of described heat tape.
It should be noted that the first of this second Preset Time and aforesaid interval time period when presetting
Between be associated.It is simple it is believed that typically to arrange second in the case of the first Preset Time is longer pre-
If the time is the most longer, and when the second Preset Time is shorter, then the first shorter Preset Time can be set.
This is because, the purpose opening heat tape is to ensure that compressor occurs without hydrops phenomenon.Therefore, by week
When heat tape is controlled by the phase, need to ensure to open heat tape certain time (the second Preset Time)
Compressor can be made within the whole cycle (the first Preset Time) all without hydrops phenomenon occurs.So, right
Need to open the time that heat tape is longer in the longer cycle, it is thus possible to ensure in week time that this is longer
Even if it is inadequate that phase interior heat tape stopping heating not resulting in compressor internal temperature yet.
Based on same inventive concept, the embodiment of the present invention provides the control dress of a kind of compressor of air conditioner heat tape
Put, solve the principle of problem and the control method phase of aforementioned a kind of compressor of air conditioner heat tape due to this device
Seemingly, therefore, the enforcement of this device can realize according to the concrete steps of preceding method, the most superfluous in place of repetition
State.
The control device of the compressor of air conditioner heat tape of one of them embodiment, as it is shown in figure 5, include ring
Border temperature detecting module 100, first performs module 200 and second performs module 300.
Wherein, ambient temperature detection module 100, when air-conditioning is in holding state, residing for detection air-conditioning
Whether outdoor environment temperature is in soaking condition；First performs module 200, for being in when outdoor environment temperature
During soaking condition, open the heat tape of compressor of air conditioner；Second performs module 300, for working as outdoor environment
When temperature is in cooling state or steady state, close heat tape.
The control device of the compressor of air conditioner heat tape of the present embodiment, according to judging that outdoor environment temperature is in
Ascent stage be in the decline stage decide whether open heat tape, when unit is standby, only ring
Border temperature opens compressor heat tape (compressor winding) heating the when of being in ascent stage.Due to one
In the middle of it, outdoor environment temperature first transition is less than temperature last transition, thus greatly reduces unlatching pressure
The time of the dynamo-electric heating tape of contracting, reduce the standby energy consumption of compressor.
As a kind of embodiment, outdoor environment temperature detection, i.e. ring can be carried out according to predetermined period circulation
Border temperature detecting module is spaced the first Preset Time and whether outdoor environment temperature is in soaking condition carries out once
Detection.
Wherein the first Preset Time can be set according to the runnability of specifically used environment and air-conditioning.As right
The use region that in the middle of Yu Yitian, variations in temperature fluctuation is bigger, can arrange shorter described first Preset Time,
It is thus possible to open heat tape according to the change of outdoor environment temperature in time, it is to avoid compressor generation hydrops is existing
As.And variations in temperature is used more smoothly to environment, relatively long described first Preset Time can be set,
Avoid frequently controlling, also reduce the computing pressure of airconditioning control part.
As shown in Figure 6, in another embodiment, ruuning situation judge module 010 and the 3rd execution are also included
Module 0101.
Wherein, ruuning situation judge module 010 is for judging the ruuning situation of air-conditioning, it is judged that current
Air-conditioning is in running status and is in holding state, and obtains judged result.According to described ruuning situation
The judged result of judge module 010, when air-conditioning is in running status, turns and performs described 3rd execution module
0101, close heat tape；And according to the judged result of described ruuning situation judge module, when air-conditioning is in
During holding state, turn and perform aforesaid outdoor environment judge module 100, thus further according to outdoor environment temperature
The switch of compressor heat tape is controlled by degree variation tendency.
