Specific implementation mode
Below based on embodiment, present invention is described, but the present invention is not restricted to these embodiments.
Air-conditioning needs detection ambient temperature to achieve the purpose that control air-conditioning in each environment operational process.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, shut-off valve 4 and 6,
Indoor heat exchanger 5, compressor 7, four-way valve 8, low tension switch 9 and high-voltage switch gear 10, outdoor heat exchanger 1 are provided with outdoor heat exchanger
Temperature sensor 2, for detecting the temperature of outdoor heat exchanger.When pressure at expulsion is more than 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 the purpose of protection compressor 7.Air-conditioning does not include for surveying
The outer shroud temperature sensor for measuring outdoor environment temperature, by reading survey of the outdoor heat exchanger temperature sensor before compressor start
Magnitude T, is used as outdoor environment temperature, the operation for controlling air-conditioning.
The present invention achievees the effect that detection environment temperature when realizing the no outer shroud temperature sensor of realization, work as ambient temperature
Air-conditioning is realized when sufficiently low and is controlled, the operational effect and reliability of air-conditioning are enhanced.
Preferably, the control method according to measured value T of the outdoor heat exchanger temperature sensor before compressor start come
Decide whether to start the measure that shielding low-voltage is protected.Since air-conditioning is under worst cold case, low pressure is relatively low, and pressure switch is low
Warm environment is worth higher phenomenon there are protection, and low-voltage variation, which easily occurs, in air-conditioning to shift to an earlier date, and therefore, it is necessary to prevent air-conditioning in low temperature environment
Report low-voltage variation in operation by mistake, it is ensured that air-conditioning, being capable of normal operation in the state that scarce fluorine is less in low temperature environment.
In one embodiment, in heating booting or refrigeration/dehumidification transformation of ownership heat pattern, when outdoor heat exchanger temperature sensing
When measured value T of the device before compressor start is less than the first preset value, shielding low-voltage protection.Due to before compressor start, room
External heat exchanger temperature is consistent with ambient temperature, therefore, outdoor heat exchanger temperature is detected by outdoor heat exchanger temperature sensor
It can be learnt that ambient temperature, and then it is compared with preset value, to determine the need for shielding low-voltage protection.
In order to avoid air-conditioning is in 0 DEG C of environment temperature or less wrong report low pressure, respectively in automatic defrosting, self-defined defrosting, minimum
Under the different operating modes such as heating, low-temperature heating, ultralow temperature heating, the outdoor heat exchanger temperature that is measured when by operation of air conditioner at least 6min
Degree, and the outdoor heat exchanger temperature measured after shutting down at least 4min, the experimental data are shown in the following table：
In experimental data, under automatic defrosting operating mode, dry-bulb temperature is 2 DEG C, and temperature is 1.21 DEG C after shutdown, difference
0.79, under self-defined defrosting operating condition, dry-bulb temperature is 0 DEG C, and temperature is -1.88 DEG C after shutdown, and difference 1.88 therefore can be with
Setting is when the preceding outdoor heat exchanger temperature sensor of compressor of air conditioner startup detects that outdoor heat exchanger temperature is less than -1 DEG C, to sky
It adjusts and implements control, air-conditioning is avoided to report low pressure by mistake below 0 DEG C of environment temperature.Therefore, in one embodiment, the first preset value is -1
DEG C, that is to say, that when measured value T of the outdoor heat exchanger temperature sensor before compressor start is less than -1 DEG C, shielding low-voltage
Protection.
In another embodiment, when refrigeration mode is switched on, when the outdoor heat exchanger temperature sensor is in compressor start
When preceding measured value T is less than the second preset value, shielding low-voltage protection.Using with heating booting or refrigeration/dehumidification transformation of ownership heat pattern
Same experimental method determines the second preset value, and in one embodiment, the second preset value is 8 DEG C, that is to say, that refrigeration mode
When booting, when measured value T of the outdoor heat exchanger temperature sensor before compressor start is less than 8 DEG C, shielding low-voltage protection is kept away
Exempt from air-conditioning wrong report low pressure.
In another embodiment, after the first preset time t of operation of air conditioner 1, the second preset time t 2 is shut down, then restart
Air-conditioning, operation of air conditioner after a certain period of time, user may shut down, and after a time, be again started up air-conditioning.Specifically, in order to avoid
Machine is frequently switched on, is preferably met, 1 >=6min of preset time t, 2 >=4min of preset time t can reduce the damage of compressor in this way
Consumption, the service life for extending air-conditioning.
Another aspect of the present invention, provides air-conditioning a kind of, including outdoor heat exchanger, is provided on outdoor heat exchanger
Outdoor heat exchanger temperature sensor, for detecting the temperature of outdoor heat exchanger, air-conditioning does not include for detecting outdoor environment temperature
The outer shroud temperature sensor of degree, also, air-conditioning is worked using the control method of air-conditioning provided by the invention, and air-conditioning is avoided to miss
Report low pressure.
Air-conditioning provided by the invention and its control method pass through the environment before the detection booting of outdoor heat exchanger temperature sensor
Temperature achievees the effect that detect environment temperature when realizing no outer shroud temperature sensor, so that air-conditioning is shielded under worst cold case low
Pressure protection, prevents air-conditioning from reporting low pressure by mistake, it is ensured that air-conditioning normal operation improves comfort, realizes that low-voltage variation is effectively and accurate.This
Outside, outer shroud temperature sensor and its fixed structure, outdoor unit control panel outer shroud terminal can be reduced, simplify control plate improves life
It produces efficiency, reduce complete machine cost.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for those skilled in the art
For, the present invention can have various modifications and changes.It is all within spirit and principles of the present invention made by any modification, equivalent
Replace, improve etc., it should all be included in the protection scope of the present invention.
