Specific embodiment
Below based on embodiment, present invention is described, but the present invention is not restricted to these embodiments.
Air-conditioning, in each environment running, needs to detect that ambient temperature reaches the purpose controlling air-conditioning.The present invention
Provide a kind of control method of air-conditioning, as shown in figure 1, air-conditioning include outdoor heat exchanger 1, orifice union 3, stop valve 4 and 6,
Indoor heat exchanger 5, compressor 7, cross valve 8, low tension switch 9 and high-voltage switch gear 10, outdoor heat exchanger 1 is provided with outdoor heat exchanger
Temperature sensor 2, for detecting the temperature of outdoor heat exchanger.When pressure at expulsion exceedes setting value, high-voltage switch gear 10 disconnects；
When pressure of inspiration(Pi) is less than setting value, low tension switch 9 disconnects, to realize protecting the purpose of compressor 7.Air-conditioning is not included for surveying
The outer shroud temperature sensor of amount outdoor environment temperature, by reading survey before compressor start for the outdoor heat exchanger temperature sensor
Value t, is used as outdoor environment temperature, for controlling the operation of air-conditioning.
Present invention achieves realizing the effect not having to reach detection ambient temperature during outer shroud temperature sensor, work as ambient temperature
When sufficiently low, air-conditioning is realized controlling, strengthen operational effect and the reliability of air-conditioning.
Preferably, described control method according to measured value t before compressor start for the outdoor heat exchanger temperature sensor Lai
Decide whether to start the measure of shielding low-voltage protection.Because air-conditioning is under worst cold case, low pressure is relatively low, and pressure switch is low
There is the higher phenomenon of protection value in warm environment, low-voltage variation easily in air-conditioning to shift to an earlier date, accordingly, it would be desirable to prevent air-conditioning in low temperature environment
In operation, wrong report low-voltage variation, it is ensured that air-conditioning is in low temperature environment, can normally be run in the state of scarce fluorine is less.
In one embodiment, when heating start or refrigeration/dehumidification transformation of ownership heat pattern, when outdoor heat exchanger temperature sensing
When measured value t before compressor start for the device is less than the first preset value, shielding low-voltage is protected.Due to before compressor start, room
External heat exchanger temperature is consistent with ambient temperature, therefore, detects outdoor heat exchanger temperature by outdoor heat exchanger temperature sensor
Ambient temperature can be learnt, and then it is compared with preset value, to determine the need for shielding low-voltage protection.
In order to avoid air-conditioning reports low pressure by mistake below 0 DEG C of ambient temperature, respectively in automatic defrosting, self-defined defrosting, minimum
Heat, under the different operating modes such as low-temperature heating, ultralow temperature heat, the outdoor heat exchanger temperature that records during by operation of air conditioner at least 6min
Degree, and the outdoor heat exchanger temperature recording after shutting down at least 4min, experimental data is as follows:
In experimental data, under automatic defrosting operating mode, dry-bulb temperature is 2 DEG C, and after shutdown, temperature is 1.21 DEG C, difference
0.79, under self-defined defrosting operating condition, dry-bulb temperature is 0 DEG C, and after shutdown, temperature is -1.88 DEG C, differs 1.88, therefore, it can
Set when before compressor of air conditioner startup, outdoor heat exchanger temperature sensor detects outdoor heat exchanger temperature less than -1 DEG C, to sky
Adjust and implement to control, it is to avoid low pressure reported below 0 DEG C of ambient temperature by mistake by air-conditioning.Therefore, in one embodiment, the first preset value is -1
DEG C that is to say, that when measured value t before compressor start for the outdoor heat exchanger temperature sensor be less than -1 DEG C when, shielding low-voltage
Protection.
In another embodiment, during refrigeration mode start, when described outdoor heat exchanger temperature sensor is in compressor start
When front measured value t is less than the second preset value, shielding low-voltage is protected.Start shooting or refrigeration/dehumidification transformation of ownership heat pattern using with heating
Determining the second preset value, in one embodiment, the second preset value is 8 DEG C that is to say, that refrigeration mode to same experimental technique
During start, when measured value t before compressor start for the outdoor heat exchanger temperature sensor is less than 8 DEG C, shielding low-voltage is protected, and keeps away
Exempt from air-conditioning wrong report low pressure.
In another embodiment, after operation of air conditioner the first preset time t 1, shut down the second preset time t 2, then restart
Air-conditioning, after operation of air conditioner certain time, user may shut down, and after a time, is again started up air-conditioning.Specifically, in order to avoid
Frequently switch on machine, preferably meet, preset time t 1 >=6min, preset time t 2 >=4min, so can reduce the damage of compressor
Consumption, the service life of prolongation air-conditioning.
Another aspect of the present invention, provides air-conditioning a kind of, including outdoor heat exchanger, outdoor heat exchanger is provided with
Outdoor heat exchanger temperature sensor, for detecting the temperature of outdoor heat exchanger, air-conditioning is not included for detecting outdoor environment temperature
The outer shroud temperature sensor of degree, and, the control method of air-conditioning that air-conditioning is provided using the present invention is operated, it is to avoid air-conditioning mistake
Report low pressure.
Air-conditioning and its control method that the present invention provides, by the environment before outdoor heat exchanger temperature sensor detection start
Temperature, realizes the effect not having to reach detection ambient temperature during outer shroud temperature sensor, so that air-conditioning is shielded under worst cold case low
Press protection, prevent air-conditioning wrong report low pressure it is ensured that air-conditioning normally runs, improve comfortableness, realize low-voltage variation effectively and accurate.This
Outward, outer shroud temperature sensor and its fixed structure, off-premises station panel outer shroud terminal, simplify control plate can be decreased, improve life
Produce efficiency, reduce whole machine cost.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For, the present invention can have various change and change.All any modifications made within spirit and principles of the present invention, equivalent
Replace, improve etc., should be included within the scope of the present invention.
