Central air conditioning centralized control system

2020-06-16 15:22

For places such as shopping malls, office buildings, schools, industrial parks, etc., central air conditioning is an essential configuration. For example, in large shopping malls, different functional areas have been set up to meet the various needs of customers, and each functional area has different temperature requirements; The pedestrian flow in the same area also varies significantly at different time periods, resulting in complex personnel flow, which puts higher demands on the air conditioning system.

The use of the central air conditioning system is mainly manually controlled during the operation of the existing air conditioning system. The opening and closing of the air conditioning, the setting of operating temperature, wind speed and direction are all based on the feeling, and the following problems will occur during use:

• Management issues with operating temperature settings: In the internal unit of air conditioning, there are generally low cooling temperatures in summer and excessive heating in winter when setting room temperature;

• Air conditioning usage time management issues: early activation and extended usage issues, air conditioning not manually turned off after work hours;

Terminal switch issue: The air conditioning temperature is too low when there are few people in the area;

• Operation record issue: Using a standalone air conditioning temperature controller to work independently without a centralized management system, without real-time air conditioning operating temperature and historical records;

• Operation and maintenance control issues: Usually, maintenance personnel carry out maintenance work after air conditioning malfunctions are reported. Analyzing and explaining the cause of the malfunction is inconvenient, and the cost of repairing the malfunction is difficult to manage, with no fixed operation and maintenance life cycle.

Faced with these complex central air conditioning usage issues, it is necessary to implement different central air conditioning management methods, which requires the use of a central air conditioning centralized control system.

Introduction to the functions of the central air conditioning centralized control system

Remote centralized monitoring

Display the air conditioning status in multiple ways;

Support separate control and group control of air conditioning;

• Air conditioning on-site controller function locking;

Remote multi terminal and mobile login.

Intelligent schedule management

Set the air conditioning to operate regularly according to the schedule;

Intelligent exclusion of weekends and designated holidays;

You can set up to one year of scheduled tasks at a time.

Energy saving management

Set the upper and lower temperature limits to ensure energy-saving operation of the air conditioner;

Lock idle air conditioning to avoid misoperation and startup;

Unattended, terminal records air conditioning operation data.

Fault alarm

Monitor the status of air conditioning faults;

Display fault codes for easy maintenance;

Record and export air conditioning fault information statistics.

Advantages of central air conditioning centralized control system

A single air conditioning management computer can connect multiple protocol air conditioning modules, enabling centralized management of indoor air conditioning units;

A local monitoring computer can manage a maximum of 5000 indoor air conditioning units, and can divide all indoor units into any number of management groups for centralized switching, setting, and monitoring management;

The air conditioning electricity cost allocation data and historical data are stored in the FLASH memory of the central controller, and do not disappear after power failure, and do not rely on the air conditioning management computer to power on and run 24 hours a day;

The system hardware can automatically supplement the login of indoor units newly connected to the system, effectively avoiding the omission of air conditioning costs.
