Abstract
An air-conditioner and the refrigerant charging method of the air-conditioner are disclosed. When a refrigerant amount determining mode is requested to be performed, whether or not the refrigerant amount in the air-conditioner is proper is automatically determined and a shortage amount of refrigerant can be charged. Thus, a user can easily check whether or not the refrigerant charged in the air-conditioner is sufficient or insufficient, and if the refrigerant is not sufficient, the user can automatically charge the refrigerant without having to entirely remove the refrigerant from the air-conditioner, thus increasing the user convenience and reducing time and costs.
