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. Mmm... the breath-taking and touchy feeling of wind from the deep mountains and dark valleys. Through analysis in its chaos simulator, Goldstar has successfully created such a feeling of freshness and serenity by analyzing the frequency of natural wind.

Generally natural wind has the following character (frequency-Magnitude), for example dark vally, sea, mountain wind.

So as to make a similar Natural wind function, Indoor fan speed is shifted to high from low or reversely in according to the CHAOS logic.

9. Deice Control

ƒU Deicing operation is controlled by timer and sensing the indoor pipe temperature. ƒU Deicing operation checks the indoor pipe temperature and Intake-air temperature at 25 minutes and 60 min-

utes on starting of heating operation, and discriminates by temperature difference.

ƒU When the heating operation passed 25 minutes, the temperature (¡ T1=TE1–TR1) is checked and memorized

with checking the indoor pipe temperture (TE1) and the indoor Intake-air temperature (TR1).

ƒU When the heating operation passed 60 minutes, deicing operation checks the indoor pipe temperature (TE2)

and the indoor Intake-air temperature (TR2), and checks the temperature difference (¡ T2=TE2–TR2) and the temperature difference ¡ Td(=¡ T1–¡ T2) of ¡ T1, ¡ T2. If the temperature difference (¡ Td) become more than the option temperature, deicing operation starts.

ƒU At that time, deicing operation time is decided. ƒU The deicing operation time stops after deicing operation started. ƒU If deicing operation start, above heating operation time is reset, so if deicing operation is finished, the heating

operation time is recounted.

ƒU The deicinig time and the operation diagram are as following.

10. Soft Dry Operation.

ƒU During Soft Dry Operation, the compressor ON temperature is the setting temperature plus 1¡ , the compres-

sor OFF temperature is the setting temperature minus 0.5¡

ƒU When the room temperature rises over the compressor ON temperature, the operation mode is switched to the

cooling mode.

ƒU When the room temperature falls between the compressor ON temperature and OFF temperature, the opera-

tion mode is switched to the Soft Dry Operation. In this temperature range, 10min. Dry Operation, 5.5min operation OFF, 1.5min. only fan operation repeat. During 10min Dry operation, even if the room temperature falls below compressor OFF temperature, 10min(MAX) Compressor ON from starting of Dry operation which includes 4 min. Compressor ON operation below the comperssor OFF temperature.

ƒU In micom dehumidify mode, control of fan speed is as following.
