Figure.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, by the following examples, it and combines attached
Figure carries out compressor of air conditioner Smaller load of the present invention operation start-up and shut-down control method, compressor of air conditioner and air conditioner further detailed
Explanation.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not intended to limit the present invention.
Shown in Figure 1, the present invention provides a kind of compressor of air conditioner Smaller loads to run start-up and shut-down control method, comprising:
S1, Ton is set as the Smaller load The shortest operation time of compressor of air conditioner, Ton is less than compressor of air conditioner normal duty
The shortest operation time；
S2, start timing when compressor of air conditioner starting, judge whether compressor of air conditioner is in Smaller load operating status；
S3, when compressor of air conditioner is in Smaller load operating status, record compressor of air conditioner runing time be t, when t >=
Ton and reach operation purpose when, control compressor of air conditioner shut down.
Such as The shortest operation time is 6min under compressor of air conditioner normal duty, in the present embodiment, sets air-conditioning pressure
The Smaller load The shortest operation time Ton of contracting machine is 3min, then compressor of air conditioner Smaller load runs 3min and reached operation purpose
(halt condition), i.e., controllable compressor of air conditioner are shut down, and runing time shortens, and reduces energy consumption.
For how judging whether compressor of air conditioner is in Smaller load operating status, present embodiment in the above control method
Provide following three kinds of judgment modes:
One, it is compared according to compressor of air conditioner real output with setting performance number, when the reality of compressor of air conditioner
When output power is less than setting performance number, judge that compressor of air conditioner is in Smaller load operating status.Setting performance number therein is
Refer to the output power critical value of compressor Smaller load operating status and normal operating condition.
Two, it is compared according to air conditioner set temperature with Current Temperatures, when the difference of set temperature and Current Temperatures is small
When set temperature difference, judge that compressor of air conditioner is in Smaller load operating status.I.e. when set temperature and current environmental temperature
Difference very little, it is meant that compressor of air conditioner only needs small-power operation that can quickly reach set temperature, meets and shuts down item
Part, then compressor is in Smaller load operating status.
Three, it is compared according to the practical monsoon intensity out of air conditioner with setting outlet air intensity value, is less than when actually going out monsoon intensity
When setting outlet air intensity value, judge that compressor of air conditioner is in Smaller load operating status.I.e. monsoon intensity is smaller out means air conditioner
Slower to the heat exchange of environment, compressor of air conditioner does not need biggish output power, then compressor is in Smaller load operation shape
State.Wherein setting outlet air intensity value refers to the outlet air critical strength of compressor Smaller load operating status and normal operating condition.
It is shown in Figure 2, base of the compressor of air conditioner Smaller load operation start-up and shut-down control method of the present invention in above embodiment
Another embodiment is additionally provided on plinth, sets the most short startup-shutdown time T of compressor, T > (Ton+Toff), wherein Toff is
The Minimum Idle Time of compressor；As t < Ton and when reaching operation purpose, control compressor of air conditioner runs to Ton and shuts down again,
And shutting down to the shortest time being again started up is (T-Ton).
When Ton≤t≤T and reach operation purpose when, control compressor of air conditioner shut down, and shut down it is most short to what is be again started up
Time is MAX { (T-t), Toff }.
As t >=T and reach operation purpose when, control compressor of air conditioner shut down, and shut down to be again started up most in short-term
Between be Toff.
The purpose of above-mentioned control method be in order to compressor runing time and downtime control, avoid compressing
Machine frequent start-stop in a short time, causes compressor damage.Such as compressor allows startup-shutdown times N to be 6 within a hour
Secondary, then the Smaller load The shortest operation time Ton of T=60min/N=10min, compressor of air conditioner are 3min, and the most short of compressor is stopped
Machine time Toff is 6min, T > (Ton+Toff).
When t is 2min and reaches operation purpose between when the compressor is operating, due to t < Ton, in order to protect compressor, control
Compressor processed, which reruns after 1min reaches Ton, shuts down, and allows compressor after the compressor shutdown time reaches (T-Ton)=7min
It is again started up.
When t is 3.5min and reaches operation purpose between when the compressor is operating, compressor shutdown is controlled, in compressor shutdown
Time allows compressor to be again started up after reaching MAX { (T-t), Toff }=6.5min.
When t is 5min and reaches operation purpose between when the compressor is operating, compressor shutdown is controlled, in compressor shutdown
Between reach and allow compressor to be again started up after MAX { (T-t), Toff }=6min.
When t is 11min and reaches operation purpose between when the compressor is operating, compressor shutdown is controlled, in compressor shutdown
Time allows compressor to be again started up after reaching Toff=6min.
In above-mentioned two embodiment, it is that air conditioner Current Temperatures reach setting temperature that compressor of air conditioner, which reaches operation purpose,
Degree, that is, reach halt condition.
The present invention also provides a kind of compressor of air conditioner, including compressor controller, compressor controller is according to above-mentioned implementation
Control method in mode controls compressor of air conditioner.
The present invention also provides a kind of air conditioners, including the compressor of air conditioner in above embodiment.
Only several embodiments of the present invention are expressed for above embodiments, and the description thereof is more specific and detailed, but can not
Therefore limitations on the scope of the patent of the present invention are interpreted as.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection model of the invention
