Abstract
Official abstract text for this publication.
A communication apparatus, an air conditioning system having the same, and a communication method for the air conditioning system using a refrigerant pipe are provided. The refrigerant pipe may be used as a transmission line to allow communications between an outdoor unit and an indoor unit, and a low frequency band signal and a core having an inductance value appropriate for the characteristic of a pipe communication frequency may be used to perform the pipe communication, which allows communications between the outdoor unit and the indoor unit without a separate communication line, resulting in minimizing noise interruption and affection of surge, and avoiding signal strength attenuation and signal radiation.
First claim
Opening claim text (preview).
What is claimed is: 1. A pipe communication system comprising: an outdoor unit; an indoor unit; a refrigerant pipe connected to and transporting refrigerant between the outdoor unit and the indoor unit; and a communication device coupled to the refrigerant pipe to transfer data back and forth between the outdoor unit and the indoor unit using a low frequency signal via the refrigerant pipe formed of electrically conductive material; and wherein the low frequency signal is a…
