Duplex air governor

Abstract

Multi-type air conditioner including an outdoor unit having a compressor, an outdoor heat exchanger, a flow path control valve for controlling a flow path of the refrigerant from the compressor, and an outdoor unit piping system, a plurality of indoor units each having an indoor expansion device, an indoor heat exchanger, and an indoor piping system, a distributor for selectively distributing the refrigerant from the outdoor unit to the indoor units and returning to the outdoor unit again proper to respective operation modes, and noise preventing means on pipelines respectively connected to the indoor units to cut off refrigerant flow into inoperative indoor units when the air conditioner is in operation, for preventing occurrence of refrigerant flow noise at the inoperative indoor units.

Description

technical field [0001] The present invention relates to a multi-type air conditioner, and more particularly, to a multi-type air conditioner capable of individually cooling or heating a plurality of rooms. [0002] This application claims priority from Korean Patent Application No. P2003-0002037 filed on Jan. 13, 2003, which is hereby incorporated by reference in this application. Background technique [0003] In general, an air conditioner is a device used to cool or heat spaces such as living spaces, restaurants, offices, and the like. Currently, in order to efficiently cool or heat a space divided into many rooms, there is a tendency to develop multi-type air conditioners. A multi-type air conditioner generally has an outdoor unit and a plurality of indoor units each connected to the outdoor unit, and the indoor unit is installed in a room to cool or heat the room when it operates in one of a cooling mode or a heating mode. [0004] However, while some of the many rooms...

AI Technical Summary

Problems solved by technology

[0004] However, while some of the many rooms within these compartments need to be heated, the rest may need to be cooled, and duplex air conditioners are limited by the fact that they always operate in only one of the cooling or heating modes due to inability to adequately meet needs

[0005] For example, although in a building, there are some rooms that have temperature differences depending on the location of the room or the time of day, due to the sunlight, when the rooms on the north side of the building need to be heated, the rooms on the south side of the building The room may need to be cooled, and existing air conditioners that operate on a single mode cannot handle this

[0006] In addition, buildings equipped with computer rooms not only need to be cooled in summer, but also have to overcome the heat load of computer-related equipment in winter, so existing air conditioners cannot adequately meet this demand
