Operation
27°C(80.6°F), it operates with
•While compressor off, the indoor fan is off when the indoor pipe temp is below 33°C(91.4°F), when above 35°C(95°F) , it operates with the low airflow speed.
•While in defrost control, the indoor is outdoor fans are turned off.
■Defrost Control(Heating)
•Defrost operation is controlled by timer and sensing temperature of outdoor pipe.
•The first defrost starts only when the outdoor pipe temperature falls below
•Defrost ends after 12 minutes passed from starting of defrost operation when the outdoor pipe temperature rises over 15°C(59°F) even before 12 minutes.
•The second defrost starts only when the outdoor pipe temperature falls below
■Fuzzy Operation
•When any of operation mode is not selected like the moment of the power on or when 3 hrs has passed since the operation off, the operation mode is selected.
•When determining the operation mode, the compressor, the outdoor fan, and the 4 way valve are off and only the indoor fan is operated for 15 seconds. Then an operation mode is selected according to the intake air temp at that moment as follows.
24°C(75.2°F) ≤ Intake Air Temp | ➲ Fuzzy Operation for Cooling |
21°C(69.8°F) ≤ Intake Air Temp<24°C(75.2°F) | ➲ Fuzzy Operation for Dehumidification |
Intake Air Temp<21°C(69.8°F) | ➲ Fuzzy Operation for Heating |
•If any of the operation modes among cooling / dehumidification / heating mode operations is carried out for 10 sec or longer before Fuzzy operation, the mode before Fuzzy operation is operated.
1)Fuzzy Operation for Cooling
•According to the setting temperature selected by Fuzzy rule, when the intake air temp is 0.5°C(0.9°F) or more
below the setting temp, the compressor is turned off. When 0.5°C(0.9°F) or more above the setting temp, the
compressor is turned on. |
|
Compressor ON Temp | ➲ Setting Temp +0.5°C(0.9°F) |
Compressor OFF Temp | ➲ Setting Temp + 0.5°C(0.9°F) |
•At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the intake air temp at that time.
26°C(78.8°F)≤ Intake Air Temp | ➲ 25°C(77°F) |
24°C(75.2°F)≤ Intake Air Temp<26°C(78.8°F) | ➲ Intake Air Temp + 1°C(1.8°F) |
22°C(71.6°F)≤ Intake Air Temp<24°C(75.2°F) | ➲ Intake Air Temp + 0.5°C(0.9°F) |
18°C(64.4°F)≤ Intake Air Temp<22°C(71.6°F) | ➲ Intake Air Temp |
Intake Air Temp<18°C(64.4°F) | ➲ 18°C(64.4°F) |
•When the Fuzzy key (Temperature Control key) is input after the initial setting temperature is selected, the Fuzzy key value and the intake air temperature at that time are compared to select the setting temperature automatically according to the Fuzzy rule.
•While in Fuzzy operation, the airflow speed of the indoor fan is automatically selected according to the temper- ature.
