In the present embodiment, the controller 11 is a control chip and has certain storage and computation (data processing) capabilities. The input interface 12 may be a wired connection interface or a wireless connection interface including, but not limited to, bluetooth, WiFi, infrared or NFC, etc. The controller 11 receives the on/off control signal of the outdoor unit 103 of the inverter air conditioner, which is sent by the thermostat 101, through the input interface 12. The indoor unit communication interface 13 and the outdoor unit communication interface 14 are wired or wireless connection interfaces.

The above process of controlling the operation of the outdoor unit of the inverter air conditioner through the target reference temperature is a case where the controller 11 does not control the operation of the outdoor unit of the inverter air conditioner for the first time.
It can be understood that the process of determining that the temperature corresponding to the real-time indoor temperature signal is close to the target reference temperature is as follows: the temperature threshold is set in advance, for example, at 24 degrees or 26 degrees or the like. And when the temperature corresponding to the real-time indoor temperature signal reaches a set temperature threshold value, judging that the temperature corresponding to the real-time indoor temperature signal is close to the target reference temperature. And when the temperature corresponding to the real-time indoor temperature signal is close to the target reference temperature, controlling the frequency reduction operation of the outdoor unit of the variable frequency air conditioner.
The controller 11 records the target reference temperature and then the frequency conversion operation control rule is as follows: in the cooling mode, when receiving a start control signal sent by the thermostat, the controller 11 controls the outdoor unit of the variable frequency air conditioner to start, obtains the current indoor temperature, determines an initial frequency of the operation of the compressor according to the difference between the current indoor temperature and a target reference temperature, and if the difference is larger, the initial frequency is higher so as to output larger cooling capacity and quickly reduce the indoor temperature; when the difference between the indoor temperature and the target reference temperature is reduced to be close, the compressor is controlled to operate in a frequency reduction mode, the close definition is that the difference T is a range value close to 0, such as T is greater than or equal to 0 and less than or equal to 1 ℃ (set according to actual needs and/or compressor performance), the frequency of the compressor is further controlled in the range according to the close degree of the indoor temperature and the target reference temperature, if the difference is smaller, the operation frequency is lower until the lowest frequency of the compressor to operate, the indoor temperature is close to the target reference temperature value, and the comfort effect is achieved. For example, for the cooling mode, the compressor is controlled to perform a down-conversion operation as the current target reference temperature is 24 ℃ when the difference between the indoor temperature value and the target reference temperature is smaller, if the indoor temperature is reduced from 30 ℃ to 25 ℃, if a further reduction of the indoor temperature value is detected, the compressor is controlled to perform the down-conversion operation when the difference between the indoor temperature value and the target reference temperature is smaller, and finally, when the indoor temperature reaches 24 ℃, the compressor is controlled to perform the down-conversion operation at a preset low frequency, so that the indoor temperature value is finally and smoothly maintained near the target reference temperature value (for example, the difference between the indoor temperature and the target reference temperature is 0.1 degree or 0.2 degree, and the like), and the fluctuation of the indoor temperature at the target reference temperature is not too large, so as to improve.
