Abstract:
An air conditioner, comprising:a refrigerating cycle system including a refrigerant compressor, a cooling evaporator equipped in an air-conditioning housing, a heating condenser equipped at an air downstream position of said cooling evaporator in said air-conditioning housing, an external heat exchanger disposed outside said air-conditioning housing, and variable flow restriction means equipped on a refrigerant flow path between said external heat exchanger and said heating condenser,said refrigerating cycle system being arranged to enable a dehumidifying operation mode in which a refrigerant discharged from said refrigerant compressor passes through said external heat exchanger after passing through, and being condensed by, said heating condenser, the refrigerant then being evaporated by said cooling evaporator to cool air introduced into said air-conditioning housing, the cooled air then being heated by said heating condenser;dehumidification-dominant air-conditioning control means for regulating a cooling dehumidification level required for said cooling evaporator by controlling a rotating speed of said refrigerant compressor according to air-conditioning environmental factors, and for regulating a blowout temperature level of conditioned air from said heating condenser by adjustment of heating performance of said heating condenser through control of a restriction opening of said variable flow restriction means, according to said air-conditioning environmental factors, when said dehumidifying operation mode is selected;signal generating means for generating a signal for allowing a user to adjust a set temperature level of said blowout temperature;blowout-temperature-dominant air-conditioning control means for regulating said blowout temperature by controlling the rotating speed of said refrigerant compressor when a signal for adjusting said set temperature level is generated by said signal generating means in said dehumidifying operation mode; andwherein the blowout-temperature-dominant air conditioning control means further maintains the restriction opening of said variable flow restriction means when the signal for adjusting said set temperature level is generated by said signal generating means in said dehumidifying operation mode.
