Duplex air governor with multiple cut-off distributors

Abstract

Multi-type air conditioner including an outdoor unit installed in an outdoor, including a compressor, a refrigerant flow controlling part connected to a discharge end of the compressor for guiding the refrigerant proper to operation conditions selectively, and an outdoor heat exchanger connected to the refrigerant flow controlling part, a plurality of indoor units each installed in a room and having an indoor heat exchanger and an electronic expansion valve having one end connected to one end of the indoor heat exchanger, a plurality of, at least two, distributors between the outdoor unit and the plurality of indoor units for improving installation freedom of the plurality of indoor units, selectively guiding refrigerant from the outdoor unit to the plurality of indoor units proper to operation conditions, and guiding the refrigerant passed through the indoor units to the outdoor unit again, and a device for shutting off introduction of the refrigerant into the distributors connected to inoperative indoor units.

Description

technical field [0001] The invention relates to a compound air conditioner, in particular to a compound air conditioner with a plurality of distributors capable of cutting off refrigerant. [0002] This application claims priority from Korean Application No. P2003-3049 filed on January 16, 2003, which application is hereby incorporated by reference. Background technique [0003] Generally, an air conditioner for cooling or heating an indoor space, such as a living space, a dining room, and an office equipment, circulates a refrigerant through a compressor and a heat exchanger to cool or heat the indoor space. [0004] Multiple air conditioners have been developed that can cool or heat rooms at the same time without being affected by the outside temperature or environment, making the indoor environment more comfortable, and as a result, all rooms can be cooled or heated in the same operating mode. [0005] Existing multi-type air conditioners have one or more outdoor units r...

AI Technical Summary

Problems solved by technology

[0007] So existing duplex air conditioners are not ideal when some rooms need to be heated and others need to be cooled

[0008] When the room structure is relatively complex, using only one distributor not only restricts the distribution of refrigerant to each room, but also makes installation difficult

[0009] In addition, long pipes from the complex structure of the room will cause a pressure drop in the refrigerant flowing into each indoor unit, which may reduce the cooling efficiency
