The inner coil pipe temperature taken is known as the second inner coil pipe temperature.
After getting the second inner coil pipe temperature, according to the second inner coil pipe temperature and inner coil pipe high temperature protection temperature
The comparison result of degree carries out following step.The inner coil pipe high temperature protection temperature is the reliability in order to guarantee the air-conditioning
The pre-set value of institute.Specifically, when the heat exchanger is maintained at ultra-high temperature for a long time, it will affect the heat exchanger
Performance even cause the loss of periphery other component that the inner coil pipe high temperature protection temperature therefore is set, in described second
When coil temperature reaches the inner coil pipe high temperature protection temperature, need to carry out safeguard measure to the air-conditioning.
If the second inner coil pipe temperature is less than the inner coil pipe high temperature protection temperature, illustrate the inner disc tube temperature of the air-conditioning
Degree then continues to control the air-conditioning under the preset mode, repeats the step in the range of reliability permission
S01, that is, the step of repeating the acquisition the first inner coil pipe temperature.
If the second inner coil pipe temperature is more than or equal to the inner coil pipe high temperature protection temperature, S06a, control are thened follow the steps
The compressor shutdown is made, and controls the air-conditioning and exits the preset mode.
Specifically, the control air-conditioning exits the preset mode and specifically includes: reading the setting mould of the air-conditioning
Formula, and control the air-conditioning and release the preset mode to enter the setting mode.The setting mode is user by distant

Mode, quick heating mode etc..The preset mode that exits refers to that control air-conditioning enters setting mode, i.e., is set according to user
Mode work.
In step S01: after obtaining the first inner coil pipe temperature, when the first inner coil pipe temperature is more than or equal to the inner disc
It when pipe limit temperature, maintains the inner blower revolving speed constant, and enter step: S02, obtaining the second indoor environment temperature, calculate
Obtain the second difference of the set temperature Yu second indoor environment temperature.
Specifically, when determining that the first inner coil pipe temperature is more than or equal to the inner coil pipe limit temperature, then again
Indoor environment temperature is obtained, for that convenient for distinguishing, will determine that the first inner coil pipe temperature is limited more than or equal to the inner coil pipe below
The indoor environment temperature reacquired when temperature processed is known as the second indoor environment temperature and (uses TInner ring 2Indicate), and calculate the setting
Second difference T of temperature and second indoor environment temperatureSetting-TInner ring 2.By the TSetting-TInner ring 2Compared with preset threshold value
Compared with the preset threshold value includes the second temperature difference threshold and third temperature difference threshold.Wherein, the second temperature difference threshold is less than the third temperature difference
Threshold value.
After step S02, when second difference is less than second temperature difference threshold (being indicated with F), that is, TSetting-TInner ring 2
It when < F, then enters step: S03, reducing the compressor frequency.
Specifically, the value range of second temperature difference threshold are as follows: -5 DEG C of 0 DEG C of < F <, for example, the F can take -
3.5 DEG C or -2 DEG C etc., that is to say, that when second indoor environment temperature is higher than the set temperature, and be higher by
When value is beyond certain value, second indoor environment temperature is further up in order to prevent, and controlling the compressor frequency reduces.
Specifically, how much it is to be executed according to pre-set control program that the compressor frequency if being specifically down to, institute
Stating control program is stored on the electric-controlled plate of the air-conditioning before factory, in the present embodiment, using most common in this field
PID (proportion, integral, differential, ratio, integral, differential) algorithm as the control program, when
So, those skilled in the art can control the adjustment compressor frequency according to other algorithms, and the present invention, which does not do this, to be had
The restriction of body.
In step S03: after reducing the compressor frequency, judging whether the compressor frequency is preset lowest frequency
Rate.
Specifically, the low-limit frequency is obtained according to pre-set heating frequency operation curve, the heating frequency
Operation curve defines the bound of the compressor operating frequency, and different outdoor environment temperatures corresponds to different heating frequencies
Curve obtains the applicable heating frequency curve of current outdoor environment temperature, so that it may obtain the low-limit frequency.
If the compressor frequency is not up to the low-limit frequency, illustrate that the compressor frequency can also continue to be dropped
It is low, continue to control the air-conditioning under the preset mode at this time, repeat the step S01, that is, repeats described obtain
The step of taking the first inner coil pipe temperature.
If the compressor frequency reaches the low-limit frequency, illustrate that the compressor frequency has reached under conditions present
Lower limit value, then, in order to prevent air-conditioning continuation continued to run according to current state cause the indoor environment temperature after
It is continuous to rise, it executes the step S04b, reduce the inner blower revolving speed.
After the step S04b, executes step S05b, obtains third inner coil pipe temperature.
Specifically reacquiring inner coil pipe temperature again when the compressor frequency reaches the low-limit frequency,
