When working frequency F is more than the higher limit of setting, the working frequency F of compressor is arranged to the higher limit;When the work of calculating
When frequency F is less than the lower limit of setting, the working frequency F of compressor is arranged to the lower limit, to ensure the operation of air-conditioning
Efficiency, extend the service life of compressor of air conditioner.
Adjustment unit 3032, the rotating speed R of indoor fan, the work frequency of compressor are adjusted according to the working frequency F of compressor
Rate F is higher, and the rotating speed R of indoor fan is higher.
A kind of optional mode is closed by the way that the working frequency F of default compressor is corresponding with the rotating speed R of indoor fan
System, rotation speed of fan is obtained according to table 2.
Another optional mode is, by computing unit 401 according to formula (2), to be determined by the working frequency F of compressor
The rotating speed R of indoor fan.
In certain embodiments, when the indoor temperature t and design temperature T temperature difference t is less than the second setting temperature difference
When T2 and the indoor humidity RH are located at beyond target humidity scope (RH1, RH2), meet condition, now computing unit 401, use
First candidate's working frequency of compressor is calculated by formula (1) in the temperature Tpn according to indoor coil;According to indoor humidity RH by
Formula (2) calculates second candidate's working frequency of compressor;Take the first candidate working frequency and second candidate's working frequency
In working frequency F of the small person of value as compressor, adjustment unit 3032, for being adjusted according to the result of calculation of computing unit 401
Save the working frequency of compressor.
In certain embodiments, when the indoor temperature t and design temperature T temperature difference t is less than the second setting temperature difference
When T2 and the indoor humidity RH are located at beyond target humidity scope (RH1, RH2), meet condition, now computing unit 401, use
The working frequency of compressor, adjustment unit 3032, by based on are calculated by formula (1) in the temperature Tpn according to indoor coil
Calculate the working frequency of the result of calculation regulation compressor of unit 401.
In certain embodiments, when the indoor temperature t and design temperature T temperature difference t is less than the second setting temperature difference
When T2 and the indoor humidity RH are located at beyond target humidity scope (RH1, RH2), meet condition, now computing unit 401, use
In the working frequency for calculating compressor by formula (2) according to indoor humidity RH, adjustment unit 3032, for according to computing unit
The working frequency of 401 result of calculation regulation compressor.
In certain embodiments, when the indoor temperature t and design temperature T temperature difference t is less than the described second setting temperature
Poor Δ T2 and when the indoor humidity RH is located within target humidity scope (RH1, RH2), keeps the rotating speed R of the indoor fan
It is constant with the working frequency F of the compressor.
In certain embodiments, adjustment unit 3032, it is additionally operable to the temperature difference t with design temperature T as the indoor temperature t
During more than or equal to the second setting temperature difference T2 and less than the first setting temperature difference T1, the working frequency F of the compressor is adjusted
It is whole to a setpoint frequency f1.
In certain embodiments, setpoint frequency f1 is the 70% of compressor highest frequency.
In certain embodiments, adjustment unit 3032, it is additionally operable to when the temperature difference t is more than or equal to the described first setting
During temperature difference T1, the working frequency F of the compressor is lifted, to reduce indoor temperature.
In further embodiments, adjustment unit 3032, it is additionally operable to when the temperature difference t is set more than or equal to described first
When determining temperature difference T1, the rotating speed R of the indoor fan is lifted, to reduce indoor temperature.
In further embodiments, adjustment unit 3032, it is additionally operable to when the temperature difference t is set more than or equal to described first
When determining temperature difference T1, the working frequency F of the compressor is lifted, while lifts the rotating speed R of the indoor fan, to accelerate to reduce
The speed of indoor temperature.
The disclosure also includes a kind of air-conditioning, including compressor and indoor fan, in addition to described in foregoing any embodiment
Device.
