Wherein, the specific value of set temperature threshold value and preset threshold is not unique, can be adjusted according to the actual situation.
Specifically, air-conditioning is after opening heating mode, as the temperature for being evaporated device inner tube of heating process can be stepped up.Control
Device calculates the difference with set temperature threshold value according to the evaporator inner tube temperature that temperature-detecting device real-time detection obtains, and works as difference
When reaching preset threshold, the compressor frequency reducing operation of air-conditioning is controlled.The frequency reducing amplitude of compressor is not unique, equally can be according to reality

In one embodiment, as shown in Fig. 2, before step S140, this method further includes step S130.
Step S130: obtaining temperature threshold and adjust reference data, adjusts reference data according to temperature threshold and determines setting temperature
Spend threshold value.
Step S130 specifically can before step S120, can also after step S120, or with step S120 simultaneously into
Row.The concrete type that temperature threshold adjusts reference data is not unique, can be air-conditioning swing flap gear, is also possible to environment temperature
Deng.Before carrying out frequency reducing to compressor of air conditioner according to inner tube temperature, controller adjusts ginseng also according to the temperature threshold got
It examines data and determines specific set temperature threshold value, frequency reducing is carried out to compressor in combination with air-conditioning practical operation situation, so that control
It is more accurate and reliable.
The type for adjusting reference data according to temperature threshold is different, determines that the concrete mode of set temperature threshold value can also correspond to
All differences.In one embodiment, it includes swing flap gear that temperature threshold, which adjusts reference data, and step S130 includes: to obtain sky
The swing flap gear for adjusting current setting, obtains corresponding set temperature threshold value according to swing flap gear.Wherein, swing flap gear and setting temperature

Relationship, when needing to carry out frequency reducing to compressor of air conditioner, according to the swing flap gear of air-conditioning actual setting and the corresponding relationship of storage
The specific value of set temperature threshold value can be directly obtained, it is simple and efficient to handle.
In one embodiment, the specific value of set temperature threshold value increases with the increase of swing flap gear.Air-conditioning is swept
Wind file position is bigger to illustrate that heating needs are bigger, the value of set temperature threshold value is improved at this time, so that evaporator inner tube be made to reach more
Electric heater is controlled after high temperature again and stops auxiliary heating, the heating effect of air-conditioning equally can be improved.Further, at this
In embodiment, with the increase of swing flap gear, the increase amplitude reduction of set temperature threshold value, for example, when user sets low wind file
When operation, the value of set temperature threshold value is 45 DEG C；When wind file operation in user's setting, the value of set temperature threshold value is 49
DEG C, the amplitude that increases is 4 DEG C；When user sets the operation of high wind file, the value of set temperature threshold value is 51 DEG C, and the amplitude that increases is 2
℃；When user sets the operation of superpower wind file, the value of set temperature threshold value is 52 DEG C, and the amplitude that increases is 1 DEG C.By set temperature

Range determines corresponding linear function.
Wherein, difference range and linear function have preset binding relationship, and linear function characterizes difference and set temperature
The linear relationship of threshold value.Specifically, temperature-detecting device may include the inner tube temperature sensor and environment temperature for connecting controller
Sensor, inner tube temperature sensor are set to evaporator, are detected to obtain inner tube temperature to evaporator inner tube temperature and are sent to
Controller.Environment temperature sensor detection air-conditioning local environment temperature simultaneously feeds back to controller, and controller is according to collected ring
Difference between border temperature computation and user's set temperature.Controller, which can preselect, stores different difference range and linear function
Corresponding relationship can directly obtain difference locating for difference after the difference being calculated between environment temperature and user's set temperature
It is worth range, corresponding linear function then can be obtained according to the corresponding relationship of storage.
Step 134: set temperature threshold value is obtained according to difference and the linear function determined.Controller is obtaining environment temperature
After linear function corresponding to difference between user's set temperature, the difference and setting that are characterized according to determining linear function
The corresponding relationship of temperature threshold can calculate setting temperature corresponding to the difference between current environmental temperature and user's set temperature
Spend threshold value.
In the present embodiment, set temperature threshold value is determined according to the difference between current environmental temperature and user's set temperature
Specific value, the actual ambient temperature in conjunction with locating for air-conditioning carry out frequency reducing to compressor, the reliability of airconditioning control equally can be improved.
The concrete type of linear function corresponding to different difference ranges is also not uniquely, specifically can be set to setting temperature
The value for spending threshold value increases as the difference between environment temperature and user's set temperature increases, and can equally make evaporator inner tube
Reach higher temperature and control electric heater stopping auxiliary heating again later, improves the heating effect of air-conditioning.Further, one
In a embodiment, the slope of linear function reduces with the increase of difference range, i.e., with environment temperature and user's set temperature
Between difference increase, the increase amplitude reduction of set temperature threshold value.For example, can be by difference range from small longer spread, most
The maximum slope of the corresponding linear function of small difference range, the slope with the corresponding linear function of the increase of difference range gradually subtract
Small, linear function slope corresponding to maximum difference range is zero.For example, difference range includes 2 DEG C -4 DEG C, 4 DEG C -6 DEG C and 6
DEG C or more, the difference of user's set temperature and environment temperature is 2 DEG C, 45 DEG C of set temperature threshold value value；User's set temperature with
The difference of environment temperature is 4 DEG C, 49 DEG C of set temperature threshold value value；Difference >=6 DEG C of user's set temperature and environment temperature, if
Determine 52 DEG C of temperature threshold value.
In the present embodiment, the increase with difference range is set by the slope of linear function and is reduced, set to reduce
Determine the elevation amplitude that temperature threshold value increases with temperature gap, it is same to can avoid for evaporator inner tube set temperature being arranged
It is high and air-conditioning is caused to damage, improve the operational reliability of air-conditioning.
Above i.e. there is provided the concrete modes of two kinds of determining set temperature threshold values, it will be understood that sets according to determining
After determining the compressor frequency redution operation that temperature threshold carries out in step S140, also detectable temperature threshold adjusts whether reference data is sent out
Changing, if so, adjusting reference data according to the temperature threshold after variation redefines set temperature threshold value, again to compression
Machine carries out frequency reducing, changes the maximum running frequency of compressor in the process of running.
In one embodiment, with continued reference to Fig. 2, before step S120, this method may also include step S110.
Step S110: after opening air-conditioning heating operation, the electric heater work that air-conditioning is controlled when meeting preset condition is detected
Make.
Specifically, after user, which controls air-conditioning by interactive device output order, opens heating operation mode, controller is also
Detection air-conditioning whether meet preset condition, if detect meet preset condition if control electric heater work carry out auxiliary heating,
Improve air-conditioning heating effect.It is appreciated that the particular content of preset condition is not to be unique, combinable specific reference frame
To adjust.For example, reference frame can be user's set temperature, environment temperature or user's enforced opening electric heating, accordingly, in advance
If condition can be, user's set temperature, which is higher than preset threshold, environment temperature is lower than given threshold or receives electric heating unlatching refers to
It enables.Wherein, when user's set temperature is higher than preset threshold or environment temperature is lower than given threshold, then it is believed that needing heating temperature
Higher or environment temperature is lower, requires by quickly heating raising room temperature, controls electric heater work at this time and carries out assisting adding
