Indoor temperature and outdoor temperature.
Step S2：As shown in Fig. 2 indoor set passes through communicating circuit with off-premises station, by the sensor temperature signals for collecting,
It is sent to outdoor host computer to be collected.
Step S3：Outdoor host computer calculates current environmental temperature according to the temperature signal for collecting, and determines current season, and
It is further accurately to judge that the demand of system running pattern lays the foundation in being stored in outdoor host computer.For example calculate current environment
Temperature is 30 DEG C, then determine current season for summer.If specific algorithm is unit is first upper electricity, can directly initiate
Season operation function, collection indoor temperature, outdoor temperature, outdoor coil temperature, outdoor discharge temperature signal, by these temperature letters
Number it is stored in temperature signal array, then carries out size sequence, remove maximum and minimum value, then calculate mean value, this is put down
