Abstract

A system includes is provided to include an air conditioner in each zone of a painting process line supplying heated air according to temperature/humidity stabilization conditions for a painting process of each zone of a spray booth. A controller transmits operation information of the air conditioner including temperatures and humidities of outdoor air flowing into the air conditioner and indoor air inside each zone of the booth and temperature/humidity stabilization condition values for each zone of the booth. A server extracts stabilization time of the operation information equal to current operation information in a database in which the stabilization time required for temperature and humidity of each both zone to reach the condition values is stored and applies operation command for the air conditioner to the controller at operation schedule time derived by calculating the stabilization time backward from a time when a vehicle arrives at each booth zone.

Claims20

Dependent claims

A system for controlling an air conditioner of a painting process line including an air conditioning equipment, a spray booth, and an exhaust equipment that are divided into a plurality of zones, comprising:

an outdoor air measuring device configured to measure temperature and humidity of outdoor air flowing into the air conditioner;
an indoor air measuring device configured to measure temperature and humidity inside each of the zones of the spray booth;
the air conditioner installed in each of the zones of the air conditioning equipment and configured to supply heated air based on temperature and humidity stabilization conditions required for a painting process of each of the zones of the spray booth;
an air conditioning controller configured to transmit operation information of the air conditioner including temperatures and humidities measured by the outdoor air measuring device and the indoor air measuring device, temperature and humidity stabilization condition values for each of the zones of the spray booth, and an operation state of the air conditioner and to operate the air conditioner when an operation command for the air conditioner is received;
and
a server configured to extract a stabilization time of the operation information of the air conditioner equal to current operation information of the air conditioner in a database in which the stabilization time required for temperature and humidity of each of the zones of the spray booth to reach the temperature and humidity stabilization condition values is stored and configured to apply the operation command at an operation schedule time of the air conditioner derived by calculating the stabilization time backward from a time when a vehicle arrives at each of the zones of the spray booth due to operation of a production line of the vehicle.

3 more elements

A method for controlling an operation time of an air conditioner by a server of a system for controlling the air conditioner that is disposed in each of zones of a painting process line, comprising:

collecting, by the server, operation information of the air conditioner including temperature and humidity measurement values of outdoor air flowing into the air conditioner, temperature and humidity of indoor air inside each of zones of a spray booth included in the painting process line, temperature and humidity stabilization condition values for each of the zones of the spray booth, and an operation state of the air conditioner from an air conditioning controller for each of the zones of the painting process line to store the collected values in a database;
searching, by the server, a stabilization time based on an operation history of the air conditioner of the operation information of the air conditioner equal to current operation information of the air conditioner in the database in which the stabilization time required for temperature and humidity of each of the zones of the spray booth to reach the temperature and humidity stabilization condition values is stored;
detecting, by the server, operation of a production line of a vehicle to calculate a time when the vehicle arrives at each of the zones of the spray booth when the production line is operated;
and
applying, by the server, an operation command for the air conditioner to the air conditioning controller at an operation prediction time of the air conditioner derived by calculating the stabilization time backward from the time when the vehicle arrives at each of the zones of the spray booth.
