NOISE FILTER, OUTDOOR UNIT, AND AIR CONDITIONER

Title:

NOISE FILTER, OUTDOOR UNIT, AND AIR CONDITIONER

Document Type and Number:

WIPO Patent Application WO/2003/058651

Kind Code:

A1

Abstract:

A noise filter for efficiently filtering out noise generated by a noise generation source inside an outdoor unit of an air conditioner in which power from the master power source is supplied through the outdoor unit to the indoor unit. Power source lines (5a, 5b) and indoor/outdoor lines (Lins) are wound around a common magnetic body to constitute a choke coil. The numbers of turns of the power source lines (5a, 5b) and the indoor/outdoor lines (Lins) are so set as to be nearly proportional to their respective impedances. The noises of both are cancelled while keeping the balance of the influence of the choke coil on a magnetic field, so that noise is efficiently filtered out.
