An integrated management system for controlling multi-type air conditioners, the system comprising: at least one air conditioner system (1∼N) having one or more air conditioner groups, wherein the at least one air conditioner system (1∼N) is configured to transmit first information related to the one or more air conditioner groups to a connection controller group; the connection controller group having at least one connection controller (101∼104) connected to the at least one air conditioner system (1∼N), and configured to convert the first information data related to the at least one air conditioner system (1∼N) based on a remote communication protocol and transmit the converted first information data; and a remote integrated management system configured to receive the first information data from the connection controller group, and remotely monitor or control the at least one air conditioner system (1∼N) based on the received first information data, characterized in that the first information data comprises one or more of operation information on the connected air conditioner system (1∼N) and connection controller type information which determines a specific connection controller controlling air conditioner system, wherein the remote integrated management system comprises a connection controller identifying module configured to analyze data received from the at least one air conditioner system through the connection controller group and identify the type of the connection controller based on the analyzed result, a protocol process module configured to perform an appropriate protocol process for the data received from the at least one air conditioner system (1∼N) through the connection controller group according to the type of the connection controller identified by the connection controller identifying module; a database server configured to store the data processed by the protocol process module; and a monitoring server configured to display operation information on a plurality of the air conditioner system (1∼N) connecting to different types of the connection controller (101∼104), wherein the connection controller type information locates in a body of the received first information data, and wherein the received first information data comprises: a header including at least one data of information related to the at least one air conditioner system and version information; and a body including at least one data of an outdoor unit identifier, a group number, an operation state, an operation mode and connection controller type information. at least one air conditioner system (1∼N) having one or more air conditioner groups, wherein the at least one air conditioner system (1∼N) is configured to transmit first information related to the one or more air conditioner groups to a connection controller group; the connection controller group having at least one connection controller (101∼104) connected to the at least one air conditioner system (1∼N), and configured to convert the first information data related to the at least one air conditioner system (1∼N) based on a remote communication protocol and transmit the converted first information data; and a remote integrated management system configured to receive the first information data from the connection controller group, and remotely monitor or control the at least one air conditioner system (1∼N) based on the received first information data, characterized in that the first information data comprises one or more of operation information on the connected air conditioner system (1∼N) and connection controller type information which determines a specific connection controller controlling air conditioner system, wherein the remote integrated management system comprises a connection controller identifying module configured to analyze data received from the at least one air conditioner system through the connection controller group and identify the type of the connection controller based on the analyzed result, a protocol process module configured to perform an appropriate protocol process for the data received from the at least one air conditioner system (1∼N) through the connection controller group according to the type of the connection controller identified by the connection controller identifying module;
