A communication device for pipes of an air conditioner disclosed herein transmits and receives communication signals using induced electromagnetic force, generated by a signal line wound around a core assembly, thereby facilitating for coupling between the core assembly and the signal line. Also, one type of core assembly can be commonly applied to various standards of pipes. Rainwater or foreign materials cannot permeate between the signal line and the core assembly by winding the signal line on the core assembly, despite of external installation, thus preventing breakdown or degraded communication performance of the communication device. Also, with forming a signal line mounting hole through the core assembly, the signal line is fixedly inserted through the signal line mounting hole, thereby preventing in advance a movement of the core assembly even though a refrigerant pipe vibrates.

Signal transmission device for air conditioner

An air conditioning system includes a plurality of indoor units and one or more outdoor units to drive the indoor units. The one or more outdoor units are coupled to the indoor units through refrigerant pipes that include one or more branch points. A calculator calculates an amount of filling refrigerant based on capacities of the indoor units and the one or more outdoor units and lengths of the refrigerant pipes.
