Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
Fig. 1 is the control method flow chart that the present invention promotes transducer air conditioning refrigeration comfort.As shown in Figure 1, described mention
Rise the control method of transducer air conditioning refrigeration comfort, comprising:
S1 determines inlet air temperature；
S2 determines that the transducer air conditioning last time shuts down reason；
S3 shuts down reason control external disk according to the inlet air temperature and the transducer air conditioning last time and prohibits raising frequency/frequency reducing
Temperature spot.
Wherein, raising frequency refers to increasing compressor operating frequency, and frequency reducing refers to reducing compressor operating frequency.
The present invention promotes the control method of transducer air conditioning refrigeration comfort, can be abnormal in hot weather and the installation of outer machine
In the case where, it reduces external disk temperature and protects point, enter unit ahead of time and prohibit raising frequency/frequency reducing protection, external disk temperature is avoided rapidly to rise
Frequently reach external disk problem break point after height, unit continuous service under extreme weather and mounting condition can be made, improve use
Family comfort.
Specifically, according to once shut down in the inlet air temperature and the transducer air conditioning reason control external disk prohibit rise
Frequently/frequency reducing temperature spot the step of in: if the inlet air temperature is greater than or equal to an inlet air temperature threshold value, and the transducer air conditioning
Last time shutdown reason is that external disk temperature protection is shut down, then controls external disk and prohibit raising frequency/frequency reducing temperature spot reduction Δ t1, i.e., by this time
Current external disk prohibits raising frequency/frequency reducing temperature spot t and is reduced to t- Δ t1.Otherwise, other corresponding protective programs of unit are executed.
In addition, the present invention promotes the control method of transducer air conditioning refrigeration comfort, according to the inlet air temperature and institute
After stating the step of transducer air conditioning last time shutdown reason control external disk prohibits raising frequency/frequency reducing temperature spot, can also further it wrap
Include: being shut down if occurring external disk temperature protection again, controlling external disk and prohibiting raising frequency/frequency reducing temperature spot reduces Δ t2, i.e., by this time when
Preceding external disk prohibits raising frequency/frequency reducing temperature spot t ' and is reduced to t '-Δ t2；Otherwise, other corresponding protective programs of unit are executed.As a result,
External disk temperature protection value is modified when external disk temperature protection is shut down by confirmation, avoids overcorrect, refrigerating capacity is not
Foot.
Wherein, to avoid frequently protecting, and guarantee the security of system of air conditioner, it is preferred that the inlet air temperature threshold value
>=42 DEG C, Δ t2 < Δ t1,2 DEG C≤Δ t2≤4 DEG C, 3 DEG C≤Δ t1≤5 DEG C.
In one embodiment, as shown in Fig. 2, the control method of the present embodiment promotion transducer air conditioning refrigeration comfort is specific
Include:
Refrigeration booting；
Determine that inlet air temperature and the transducer air conditioning last time shut down reason (the i.e. preceding primary shutdown of this refrigeration booting
Reason)；Wherein, temperature sensor can be arranged in the air intake surface of the condenser of transducer air conditioning to be acquired inlet air temperature, from
And determine inlet air temperature, by determining that inlet air temperature can determine outside environment temperature；
Determine whether the inlet air temperature T is greater than or equal to an inlet air temperature threshold value T1, and one on the transducer air conditioning
Whether secondary shutdown reason is that external disk temperature protection is shut down；Whether it is greater than or equal to an air inlet temperature by the determination inlet air temperature T
Degree threshold value T1 can determine whether outside environment temperature is excessively high, if inlet air temperature T is greater than or equal to an inlet air temperature threshold value T1, really
It is excessively high to determine outside environment temperature, in the present embodiment, the inlet air temperature threshold value T1 is set as 43 DEG C；
If the inlet air temperature T is greater than or equal to an inlet air temperature threshold value T1, and the transducer air conditioning last time shuts down
Reason is that external disk temperature protection is shut down, then controls external disk and prohibit raising frequency/frequency reducing temperature spot (i.e. corresponding to external disk taboo raising frequency/frequency reducing point
Temperature value) reduce Δ t1；Otherwise, external disk is not corrected and prohibits raising frequency/frequency reducing temperature spot, executes other corresponding protection journeys of unit
Sequence；In the present embodiment, Δ t1 is set as 5 DEG C；
It is switched on afterwards operation reducing external disk and prohibiting raising frequency/frequency reducing temperature spot Δ t1 (5 DEG C), if occurring external disk temperature protection again
The case where shutdown, then control external disk temperature raising frequency point/frequency reducing point continues to reduce Δ t2 after being switched on again；Otherwise, external disk is not corrected
Prohibit raising frequency/frequency reducing temperature spot, executes other corresponding protective programs of unit；In the present embodiment, Δ t2 is set as 3 DEG C；
After reducing external disk and prohibiting raising frequency/frequency reducing temperature spot Δ t2 (3 DEG C), raising frequency/frequency reducing temperature no longer is prohibited to external disk and is clicked through
Row amendment, until repeating abovementioned steps after refrigeration booting next time.
In the present embodiment, other described protective programs refer to the protective programs such as conventional current protection, exhaust protection.
The present embodiment control method prohibits raising frequency/frequency reducing temperature spot, setting refrigeration external disk temperature compensation by control external disk
Value, unit easily frequently protects shutdown when solving the improper installation of refrigeration mode, outer machine or high outside environment temperature extremes
Problem, while being distinguished with normal mounting operating condition.
Fig. 2 is the controling device structure diagram that the present invention promotes transducer air conditioning refrigeration comfort.As shown in Fig. 2, institute
State promoted transducer air conditioning refrigeration comfort control device include:

Control module is connect with first determining module and the second determining module, for according to the inlet air temperature and
The transducer air conditioning last time shuts down reason control external disk and prohibits raising frequency/frequency reducing temperature spot.
Specifically, the control module is used to be greater than or equal to an inlet air temperature threshold value T1, and institute in the inlet air temperature T
When stating the transducer air conditioning last time to shut down reason being that external disk temperature protection is shut down, control external disk, which prohibits raising frequency/frequency reducing temperature spot, to be reduced
Δt1。
Further, the control module is also used to after external disk to be prohibited to raising frequency/frequency reducing temperature spot and reduces Δ t1, is gone out again
When existing external disk temperature protection is shut down, external disk, which is prohibited raising frequency/frequency reducing temperature spot, reduces Δ t2.
Wherein, it is preferred that inlet air temperature threshold value T1 >=42 DEG C；Δ t2 < Δ t1,2 DEG C≤Δ t2≤4 DEG C, 3 DEG C≤
Δt1≤5℃。
