Abstract
Description
The present invention relates to an apparatus for air conditioning.
The air conditioner is a device that discharges cold air into the room to create a pleasant indoor environment. This air conditioner is installed to provide a more comfortable indoor environment to humans by adjusting the room temperature and purifying the room temperature.
Generally, the air conditioner includes an indoor unit that is configured as a heat exchanger and installed in a room, and an outdoor unit that is composed of a compressor, a heat exchanger, and the like and supplies the refrigerant to the indoor unit.
On the other hand, a server, which is a storage medium used in a large-capacity computer system, must be maintained at a certain temperature or less for stable operation. Therefore, in a large business case, a server room is collected and managed, and an air conditioner is installed in the server room to manage the server room at a certain temperature or less.
It is an object of the present invention to provide an air conditioner which can maintain the temperature of the server room at a constant level.
An air conditioner according to an example of the present invention includes at least one outdoor unit and at least two indoor units connected to the outdoor unit, and the outdoor unit communicates with the first indoor unit operating among the at least two indoor units, And if it is determined that the first indoor unit is not operating normally, transmits a control signal to the second indoor unit in the standby state to operate the second indoor unit.
The outdoor unit generates the control signal such that the second indoor unit operates in the same manner as the operation setting of the first indoor unit.
The first indoor unit transmits an event signal including an error code to the outdoor unit.
The outdoor unit periodically communicates with the first indoor unit and operates the second indoor unit when communication with the first indoor unit is not performed for a predetermined time.
The outdoor unit alternately operates the first indoor unit and the second indoor unit in accordance with a predetermined time.
The outdoor unit counts the predetermined time to control the first indoor unit to operate for the predetermined time and then stops the operation of the first indoor unit and controls the second indoor unit to operate for the predetermined time .
The outdoor unit transmits a push notification message to the mobile terminal indicating that the operation of the first indoor unit is stopped.
The first and second indoor units include a wi-fi module, and the mobile terminal is connected to the first and second indoor units through wi-fi communication.
The outdoor unit transmits the push notification message to the mobile terminal through the second indoor unit.
The push notification message includes a comment indicating that the operation of the first indoor unit is stopped and an error code.
The air conditioner according to an exemplary embodiment of the present invention operates so that other indoor units that are in a hibernation state can operate normally even if one of the indoor units in the server room does not operate normally. As a result, even if the indoor unit does not operate normally, the temperature of the server room rises sharply and problems can be prevented from occurring in the server.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Claims (10)
And at least two indoor units connected to the outdoor unit,
The outdoor unit includes:
Determining whether the first indoor unit is in operation through communication with the first indoor unit operating among the at least two indoor units,
And transmits the control signal to the second indoor unit in a standby state when the first indoor unit is determined not to operate normally, thereby operating the second indoor unit.
Wherein the outdoor unit generates the control signal such that the second indoor unit operates in the same manner as the operation setting of the first indoor unit.
