More Information
Summary:An air conditioner is provided to add refrigerant during a heating mode without temporal mode change to a cooling mode, thereby injecting the refrigerant as much as required and preventing damage possibly generated by sudden mode conversion to the cooling mode. An air conditioner includes a first service valve(40) for adding refrigerant in a heating mode without mode conversion, and a second service valve for adding refrigerant in a cooling mode. The first service valve is mounted to refrigerant pipes between an indoor heat exchanger(32) and an expansion valve(22). The first service valve has a first coupling part(45) coupled with the refrigerant pipe(24a) connected to the indoor heat exchanger, a second coupling part(47) coupled with the refrigerant pipe(24b) connected to the expansion valve, an opening/closing valve coupling part(49) mounted with an opening/closing valve(56) for opening/closing the refrigerant pipe connected to the first coupling part by reciprocation motion, and a check valve coupling part(50) to be coupled with an additional refrigerant tank(70) and mounted with a check valve(51) for guiding the added refrigerant into the first service valve.
