General Functionality Si04-11540 Main Function1.19 Dew Condensation Sweating Prevention FunctionOutline During Cooling/Dry operation, when the heat exchanger’s temperature falls down excessively,the capacity supply will be reduced (frequency step down) so as to prevent dew formationaround a discharge grille caused by a excessive capacity supply to an indoor unit.Processing 1. Conditions of beginning/ending for this function. Operation mode is in Cooling/Dry. Compressors operate. Fan speed < MH tap Outdoor temperature ≤ 32°CDew condensation sweating prevention function will start, if are under thesimultaneous condition with AND. Operation mode is not in Cooling/Dry. Compressors stop MH tap ≤ fan speed Outdoor temperature > 32°CDew condensation sweating prevention function will be completed if are under thecoordinate condition with OR.2. Control details" It controls the operation frequency in accordance with the temperature zone in the stepdown area ~ the return area which are set in every model." Frequency limitation by means of freeze protection control will not be carried out in the returnarea." Frequency is increased approximately every 2 Hz/min. in the up-area." Frequency alteration will not be conducted in the steady area." Frequency - down is carried out in the step down area approximately every 2 ~ 4 Hz/min.DCTUYU : Heat exchanger temperature of dew condensation sweating preventionDCTUYU+3˚CDCTUYU+1˚C(Return area)(Up-area)(Steady area)(Step down area)DCTUYU+2˚CDCTUYUat the descend ofheat exchanger temp. at the rise of heatexchanger temp.(R1923)Setting a constant J type pair J type multi.DCTUYU Room temp. × 0.94 - 12.5 11°C
