The value of the fiducial value of continuous running time, these values, which can be, rule of thumb to be set.For example, if indoor coil pipe
Then need to enter defrost pattern less than 48 degree, then 48 degree of value is exactly empirical parameter here, it is this be designer or
The person that is equipment development is rather than actually measured by empirically determined.
For example, above-mentioned defrost condition may is that
1) when entering heating mode probably after five minutes, outdoor unit coil temperature and indoor environment temperature are in three minutes
Maximum difference is greater than default value；
2) when indoor coil pipe and the difference of indoor environment temperature reduce 5 degree or more and continue 3 minutes or more；
3) the compressor accumulation working time is more than 45 minutes；

Air conditioner is when heating stable operation, if heat exchanger frost-free, system low-voltage will fluctuate smaller, heat exchanger
Too great fluctuation process will not occur for middle copper pipe temperature, therefore, heat exchange amount stablize, then temperature fluctuation detected by temperature sensing device also compared with
It is small.
It is run in air-conditioning heating, after heat exchanger starts frosting, causes system low-voltage to reduce because heat exchanger caloric receptivity is reduced, tie
Copper pipe temperature declines at white position, and temperature sensing device temperature detected will decline on the inside of heat exchanger, causes because frost layer gradually thickeies
System low-voltage continues to decline, and the temperature value on the inside of heat exchanger detected also will be reduced persistently.When frost thickness reaches some point
Afterwards, because the blocking of frost layer causes outside air to be not easy at heat exchanger, temperature sensing device in air detected by heat exchanger
The accounting of heat absorption will gradually reduce, and the trend risen will be presented in temperature sensing device temperature.By multiple groups experimental verification, in Frost formation process

If heat exchanger frosting, it necessarily will appear temperature on the inside of heat exchanger and be first gradually reduced the process being stepped up again, pass through
Test is crossed, minimum temperature point and system enter heat exchanger inside detected temperature difference when defrost, therefore, can up to 10-20 DEG C
Using by such case as unit whether one of the necessary condition of frosting.
Specifically, can determine the need for entering defrost state based on the above principles as follows, to avoid " nothing
The appearance of white defrost " phenomenon:
S1: when air conditioner heat-production is run, systems stay detects and records the temperature value on the inside of heat exchanger；
S2: it, using current time as t, is currently examined according to existing control method when unit judgement need to enter defrost
Temperature value is T1, temperature sensing device minimum temperature T2 detected in A minutes before filtering out t on the inside of the heat exchanger measured, wherein
Unit for the first time heating operation when, A takes 60min, and defrost process record once terminates from defrost to another time unit if it exists later
The time t1 that unit is run is opened in defrost, and A takes t1, and A takes 60min if unit is without defrost process.
S3: determining whether T1-T2 is more than or equal to T3, if it is larger than or equal to T3, it is determined that unit frosting, if less
In T3, it is determined that the non-frosting of unit, without defrost.Wherein, T3 can be runs according to environment temperature, unit load and unit
The factors such as situation correlation are related, can be determined by experiment.For example, T3 can be with value for 10-20 DEG C DEG C.
For example, above-mentioned existing control method may is that
For example, above-mentioned defrost condition may is that
1) when entering heating mode probably after five minutes, outdoor unit coil temperature and indoor environment temperature are in three minutes
Maximum difference is greater than default value；
2) when indoor coil pipe and the difference of indoor environment temperature reduce 5 degree or more and continue 3 minutes or more；
