Refrigerant exchange capacity between indoor unit.
When first object running frequency is less than preset threshold frequency, illustrate if compressor is run according to first object
Frequency is run, and refrigeration effect influences whether the comfort of air conditioner with regard to unobvious.
To improve the comfort of air conditioner, in the present embodiment, confirming that first object running frequency is less than preset threshold value
When frequency, increase the refrigerant exchange capacity between outdoor unit of the air conditioner and indoor unit.
It is understood that increasing outdoor if outdoor temperature is constant in one timing of indoor temperature for being equipped with air conditioner

Fruit is relatively poor.On the other hand, target cold medium flux corresponding with first object running frequency levels off to max-thresholds shelves, refrigeration
Compensation dynamics levels off to utmostly.By the refrigeration phase of the refrigeration of compressor and max-thresholds shelves target cold medium flux
Superposition, so that it may to weaken the influence that compressor low-frequency operation generates air conditioner refrigeration effect, to promote the comfortable of air conditioner
Property.
And first object running frequency level off to preset threshold frequency when：On the one hand, if compressor is transported with first object
Line frequency is run, then will level off to normal operating conditions.On the other hand, target refrigerant stream corresponding with first object running frequency
Amount levels off to minimum threshold shelves, and refrigeration compensation dynamics levels off to minimum degree.Used in refrigeration by compressor with minimum threshold shelves
The refrigeration of target cold medium flux is superimposed, so that it may to compensate the shadow that compressor low-frequency operation generates air conditioner refrigeration effect
It rings, to promote the comfort of air conditioner.
By in this present embodiment, when compressor operating frequency is relatively low, being freezed according to compressor operating frequency increase
Compensation dynamics reduces refrigeration compensation dynamics when compressor operating frequency is relatively high according to compressor operating frequency.Therefore,
No matter the running frequency height of compressor, after refrigeration compensates, the refrigeration effect of air conditioner is all close.In this way, can be into one
Step promotes the comfort of air conditioner.
