Description

System and Method for Remote Management of Air Conditioner

The present invention relates to a remote management system for a refrigeration air conditioner, and in particular, a remote monitoring device remotely manages a refrigeration air conditioner that can quickly and easily manage a plurality of refrigeration air conditioners by remotely transmitting and receiving information through a communication network with a refrigeration air conditioner. System and method.

In general, among refrigeration and air conditioning units such as cold / hot water units, absorption chillers, turbo chillers, screw chillers, or cooling towers, regular inspection and maintenance must be performed to maintain optimal functions, and after-sales service (A / S) is required from time to time. There are many devices that do.

However, since most consumers do not have enough knowledge about these devices, it is impossible for them to completely check and manage the operation status of the devices themselves. We provide after-sales service (A / S) such as checking the operation status of the machine, replacing and repairing consumable parts, and checking for abnormalities.

However, this conventional after-sales management method shortens the life of the device because the after-sales service is not made at the appropriate time, and in particular, since each customer cannot easily identify the minute defects generated in the device, It is often left to repair what has been repaired as it is, leading to serious damage.

In addition, the conventional after-sales management method for these devices is a way that the after-sales service is initiated by a telephone call or visit to the consumer of the after-sales service or a visit to the after-sales center of the customer, so that the expert causes the breakdown. The problem is that without knowing the exact situation of the device, it is often time-consuming to identify and repair the cause of the failure, and the equipment manufacturer spends considerable money on after-sales service.

As a countermeasure for improving the after-sales problem of such devices, a system for detecting a failure part of the device and informing the A / S center of the device has been developed and operated.

These systems can reduce the time and expense of repairing a fault before a visitor can identify the cause of the failure in advance, but it does not contribute to the prevention of failure by continuously checking the condition of the device. Initial status information or changed information should be set through direct device operation.

As described above, the conventional refrigeration and air conditioning equipment management system has a problem that can not prevent the device failure that can be prevented in advance to reduce the life of the device and takes excessive time and cost to recover the failure.

The present invention is to solve the problems as described above, the purpose of the remote monitoring device located in the A / S center by transmitting and receiving the status information, management information or driving schedule information of the device through communication with the refrigeration air conditioning equipment, By identifying and controlling the status of the relevant device from a remote location, it is possible to prevent the occurrence of a failure due to a minor cause in advance and to cope with the occurred device failure quickly.
