Ambient temperature value；Wherein, the default ambient temperature value of the matching outdoor environment temperature T1, its matching condition include it is equal and/
Or in threshold range, that is, the outdoor environment temperature T1 for having got is equal to default ambient temperature value；Or outdoor environment temperature T1 with
The difference of default ambient temperature value is in allowed band；Or outdoor environment temperature is in two default environment temperatures (including two phases
The default environment temperature of neighbour has set two fixed default environment temperatures) between.According to the default environment temperature when
The environment temperature in the range of air-conditioner refrigerating operaton that preceding air-conditioner temperature threshold is set, the preset temperature has multiple, it is adaptable to
The contrast of the environment temperature in any time.The matching condition is configured according to the related function that sets of current air-conditioner.
If the matching way for having set is that the outdoor environment temperature T1 for getting is equal with default ambient temperature value, confirm
Whether the current outdoor environment temperature T1 for getting is equal with default ambient temperature value, then the outdoor environment temperature T1 that will be measured
Units is accurate to, as the outdoor environment temperature T1 for measuring after having the temperature value beyond units by rounding up, or
Person has the temperature value beyond units directly to take its integer as outdoor environment temperature T1；The default environment temperature that confirmation has been set
In whether have the default ambient temperature value equal with the outdoor environment temperature T1, if so, then thinking default outdoor environment
There is the default environment temperature matched with outdoor environment temperature T1 in temperature.Wherein, by default outdoor environment temperature T1 with it is default
When ambient temperature value is matched, if default environment temperature has the default ring with default outdoor environment temperature T1 deviations in allowed band
Border temperature value, is also considered as having the default environment temperature matched with outdoor environment temperature T1 in default outdoor environment temperature.
If the matching way for having set is the outdoor environment temperature T1 for getting being in preset threshold range, confirm to work as
Before the outdoor environment temperature T1 that gets whether in the threshold range in default ambient temperature value, the then outdoor ring that will be got
Border temperature T1 is directly contrasted with default ambient temperature value, if the outdoor environment temperature T1 is in two adjacent default environment temperatures
Between value, then confirm there is the threshold value for matching outdoor environment temperature T1 in default environment temperature.For example, the outdoor environment temperature for measuring
Degree T1 is 28.45 DEG C, and the default ambient temperature value for having set has 27 DEG C, 28 DEG C, 29 DEG C, according to comparison result, the outdoor ring
Border temperature T1 is between default 28 DEG C and 29 DEG C of ambient temperature value, then have matching outdoor environment temperature T1 in default environment temperature
