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, an outdoor expansion device for expanding liquid refrigerant introduced thereto in a condensed state via indoor units and providing to the outdoor heat exchanger when the room is heated, 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 means for super cooling the refrigerant condensed at the outdoor heat exchanger or the indoor heat exchangers and flowed to the indoor expansion devices or to the outdoor expansion device, thereby super cooling the refrigerant supplied to the evaporator.

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. P2003-0002035 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 heat or cool 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 a cooling mode or a heating mode. [0004] However, while some of the many rooms within these compa...

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 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
