Air conditioning implement fall in normal moving circumstance, send wind and answer wind (indoor temperature) difference in temperature should be in 8 ℃ above, if short of, show air conditioning implement refrigeration capacity is insufficient, ought to prove a cause. The cause that causes commonly may be: Refrigeration bear overload or room are too big; Install place impropriety, air current circulates to wait inadequately.

Find out above all whether because of air conditioning implement place of refrigeration bear overload is caused, should try to reduce refrigeration negative charge or increase air conditioning implement refrigerating capacity.

See air conditioning again implement installation is proper, beside the meeting when impropriety makes air cooling does not blow a person, make the person feels not cold.

High above in the sky is moved implement air current circulates not when free, if the knot on evaporator is grey much, jammed wing piece the aperture between, or air screen pack is stemmed by dirt, as a result circular wind is reduced, air conditioning implement refrigerating capacity cannot be developed adequately.
