Abstract (en)
[origin: WO2008016228A1] A method for controlling an electronic expansion valve (EEV) in an air conditioner using a compressor includes the steps of: (a) opening the EEV completely when a power is applied to the air conditioner in stand-by mode; (b) closing the EEV completely when the air conditioner starts a cooling or a heating operation; (c) calculating an indoor heat load; (d) calculating a reference opening pulse frequency of the EEV; and (e) controlling in a stepwise manner an opening pulse frequency of the EEV based on the reference opening pulse frequency of the EEV. The opening pulse frequency of the EEV is controlled in a stepwise manner until it reaches the reference opening pulse frequency of the EEV.
