Problems solved by technology

[0005] However, with the existing multi-unit air-conditioning system configured as above, in order to access the outdoor unit O through the external Internet, it is necessary to assign a recognized IP address to the outdoor unit O. When it is installed on each floor, that is, when there are many outdoor units, it is necessary to assign public IP addresses to the corresponding outdoor units. As a result, there is a problem of increasing costs and wasting IP addresses.
[0006] In addition, in order to distinguish the respective outdoor units, the recognized IP addresses given are also different. Therefore, when you want to control a specific indoor unit in the building through the external Internet, you must connect to the IP address connected to the corresponding indoor unit. Therefore, when controlling an unspecified number of indoor units, it is impossible to control them at the same time, and they must be connected to each outdoor unit separately, which is very inconvenient

Embodiment Construction

[0033] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Such as figure 2 As shown, the first embodiment of the centralized control type multi-unit air-conditioning system of the present invention consists of a plurality of indoor units I, a plurality of outdoor units O1-O3 connected to the indoor unit I, and a plurality of outdoor units O1-O3 connected with the plurality of outdoor units O1-O3 respectively. The local control units L1-L3 connected to O3 are composed of a communication protocol conversion unit P. The communication protocol conversion unit P is connected to the local control units L1-L3 through an internal network, and converts the communication standard of the data to be sent / received. so that the local control units L1-L3 can transmit / receive data with the external Internet according to the Ethernet (Ethernet) standard.

[0035] Here, the local unit control units L1 to L3 ca...

Abstract

An integrated controlled multi-air conditioner system comprising a plurality of groups of indoor units, a plurality of outdoor units connected with the indoor unit groups, respectively, at least one local control unit connected in common with the outdoor units over an internal network for controlling operations of the outdoor units, and a protocol conversion unit connected with the local control unit. The protocol conversion unit is adapted to convert different communication protocols of data transmitted and received between an external Internet network and the internal network into each other to transfer a control command received over the external Internet network to at least one of the outdoor units. The multi-air conditioner system can be efficiently controlled from the internal network and external Internet network, resulting in a reduction in manpower and time for air conditioner management. The multi-air conditioner system is also economical in that it has a reduced number of public IP addresses assigned thereto.

Description

technical field [0001] The present invention relates to a centralized control type multi-machine air-conditioning system, in particular to such a centralized control type multi-machine air-conditioning system. The air conditioning system has a communication protocol conversion unit that can convert and process different communication specifications. At the same time, because of the centralized control unit, it can reduce the number of recognized IP addresses required for remote control through the Internet, and can improve control management. the convenience of the reader. Background technique [0002] Recently, a low-cost and high-efficiency air conditioning system has been constructed by installing multiple indoor units in a large-scale building or home, and controlling the circulation and distribution of refrigerant to each indoor unit by an outdoor unit connected to these indoor units. Examples of systems are growing. Especially in the case of a large building where ce...
