The present disclosure provides an air conditioner system that includes a plurality of air-conditioners, and a management server configured to receive air-conditioner data from the plurality of air-conditioners, and to analyze the received air-conditioner data to diagnose a state of the air-conditioners. The management server is configured to perform a first or short term diagnosis of the state of the air-conditioners. The management server to perform a second or long term diagnosis of the state of the air conditioners during a certain period, based on a result of the first diagnosis.

Air-conditioner system and control method, with first and second abnormality diagnosis

An air conditioning system including a management server for analyzing data being received from at least one air conditioner at a predetermined time interval and for diagnosing a state of the air conditioner is provided. The condition of the air conditioner is diagnosed in real time through the analyzing of the data on the air conditioner. Performance deterioration on the air conditioner corresponding to variations over a certain period is diagnosed with data calculated or accumulated on a performance and an efficiency based on the data relating to the air conditioner.

Air conditioning system and control method thereof

A display device and a mobile device are disclosed. The display device comprises a memory; a display module; a communication module performing communication with at least one server; and a controller controlling the memory, the display module and the communication module. Particularly, the controller changes a content output through the display module in accordance with position information of the mobile device, which is received from the server.

Display device and mobile device

Systems and methods for forming nanoparticles in-situ are disclosed herein. The nanoparticles may be formed in-situ through thermocycling a solution comprising at least one of a molten salt, a surfactant, and a catalyst. The nanoparticles may form in the solution itself and/or on surfaces of a vessel in which the solution is formed. Nanofins may be formed from the agglomeration of particles in the solution and on surfaces. Microchannels may be formed by these nanofins, and in some cases microchannels on a surface may have nanofins form on the surface. In some embodiments, a previously formed solution that has nanoparticles formed in-situ may be used to generate nanofins in a vessel, on a wafer in a vessel, in the solution itself, or combinations thereof.

Systems and methods for in-situ formation of nanoparticles and nanofins

The present disclosure discloses a remote maintenance server for remotely maintaining at least one maintenance point provided with an air conditioner having a plurality of indoor units performing air conditioning and at least one outdoor unit connected to the indoor units to drive the indoor units, the remote maintenance server including a display unit configured to display a maintenance screen for maintaining the at least one maintenance point, and a controller configured to control at least one of at least one of an operation rate for the plurality of indoor units, a set temperature, and a compression capacity of a compressor contained in the air conditioner according to a control setting value, and control the display unit to display control information which is information associated with at least one of a control status and a control result in which at least one of the control setting value, the operation rate, the set temperature and the compression capacity is controlled in a first region on the maintenance screen.

Remote maintenance server, total maintenance system including the remote maintenance server and method thereof

A communication apparatus, an air conditioning system having the same, and a communication method for the air conditioning system using a refrigerant pipe are provided. The refrigerant pipe may be used as a transmission line to allow communications between an outdoor unit and an indoor unit, and a low frequency band signal and a core having an inductance value appropriate for the characteristic of a pipe communication frequency may be used to perform the pipe communication, which allows communications between the outdoor unit and the indoor unit without a separate communication line, resulting in minimizing noise interruption and affection of surge, and avoiding signal strength attenuation and signal radiation.
