Embodiment Construction

[0024] The structure of the air conditioning system capable of group control in the present invention will be described below with reference to FIG. 2 . In this specification, a compound air conditioning system is exemplified, but the present invention is also applicable to a stand-alone air conditioning system.

[0025] The composite air conditioning system includes: an indoor unit 20 installed in each indoor unit; and an outdoor unit 30 shared with the plurality of indoor units and distributing and controlling the flow of refrigerant circulating in the indoor units.

[0026] In addition, the group controller 10 is a device connected to one of the indoor units described above to transmit a group control command, and an example thereof is a wired remote controller.

[0027] Assuming that a wireless modem (not shown) capable of wireless communication is installed in the indoor unit 20 and the group controller 10, the group control can be performed by using a wireless remote con...

Abstract

An air conditioner system with cluster control function is composed of multiple indoor sets consisting of one indoor master set and more than one indoor slave sets, a cluster controller for sending cluster control command to said indoor master set to control all indoor sets and receiving state and error information from all indoor sets, and a outdoor set. Its operation method is also disclosed.

Description

technical field [0001] The present invention relates to an air-conditioning system capable of group control and an operation method thereof. In the present invention, among a plurality of indoor units constituting the air-conditioning system, one is set as the master indoor unit and the others are set as slave indoor units, so that by controlling the The master indoor unit can control multiple slave indoor units belonging to the same group. Background technique [0002] The structure and existing problems of an air-conditioning system capable of group control in the prior art will be described below with reference to FIG. 1 . [0003] Air-conditioning systems are divided into stand-alone air-conditioning systems and composite air-conditioning systems according to the connection mode of indoor units and outdoor units. [0004] The stand-alone air-conditioning system includes: an indoor unit installed in each room; and an outdoor unit connected one-to-one with the indoor unit...
