6.Natural Wind by CHAOS logic
There are common rules in the irregular changes amid the breeze of highlands and valleys, the sound of
streams, the songs of birds in the forest and brain waves of relaxation.
streams, the songs of birds in the forest and brain waves of relaxation.
Mmm.... the breath-taking and touchy feeling of wind from the deep mountains and dark valleys.
Through analysis in its chaos simulator, Goldstar had successfully created such a feeling of freshness and
serenity by analyzing the frequency of natural wind.

8.Hot-Start Control
• The indoor fan stops until the evaporator piping temperature will be reached to 28°C.
• During heating operation, if piping temperatures falls below 26°C fan stops.
• The operation diagram is as following.
9.Defrost Control
• Defrost operation is controlled by timer and sensing temperature of outdoor pipe.
• The first defrost starts only when the outdoor pipe temperature falls below -6°C after 60 minutes passed from
starting of heating operation and more than 10 minutes operation of compressor.
• Defrost ends after 12 minutes passed from starting of defrost operation or when the outdoor pipe temperature
rises over 12°C even if before 12 minutes.
• The second defrost starts only when the outdoor pipe temperature falls below -6°C after 60 minutes passed from
ending of the first defrost and more than 10 minutes operation of compressor.
