Background of the programme

With the rapid development of China's economy, people's living and working environment has been greatly improved, whether it is in high-end office buildings, or ordinary factory offices, central air conditioning has basically become the basic configuration of these public commercial or office areas, central air conditioning is convenient to use, comfortable, no noise, beautiful appearance has many advantages, due to the use of air conditioning control principle does not understand and energy saving awareness is weak, arbitrarily switch on and off air conditioning and set air conditioning, resulting in the use of air conditioning has a great waste of resources image, It has brought a big problem in management, so the problem of high energy consumption in the use of central air-conditioning public buildings is becoming increasingly prominent.

Overview of the scenario

At present, the main central air conditioning on the market is controlled by independent air conditioning thermostat mode, that is: each room is wall-hung with an independent control panel, and the opening of the air conditioning is manually operated by personnel entering the room, although this way is easy to operate, but the management personnel can not know the opening and running status of all air conditioners and the remote control function, Zonghengtong central air conditioning centralized management program through the use of independent research and development of the central air conditioning centralized manager (ACPower) to achieve the centralized switch and temperature setting of air conditioning in all rooms , mode setting and other remote management functions, and at the same time support mobile APP direct management, its operation management is simple and intuitive. The main functions are as follows:

1. Realize unified monitoring and management functions for single or group multiple air conditioners;

2. Realize the functions of remote power on/off, operation mode setting, running temperature setting, etc.;

3. Support energy-saving control functions such as automatic setting of operating temperature and automatic power on/off;

4. Support air conditioning operation data saving, automatic generation of reports and statistical analysis functions.

Schematic design

Zonghengtong central air conditioning centralized management solution through the deployment of a Zonghengtong central air conditioning centralized manager (ACPower) in each room that needs to be used independently for central air conditioning, the central air conditioning centralized manager can be built-in multi-type communication modules, supporting: RS485 communication module, Ethernet module, wireless LoRa communication module, wireless WIFI communication module (default), etc., the operation data information and control interface of the air conditioner are networked through different communication modules. Finally, it is converged to the central air-conditioning background centralized management system to realize the real-time monitoring of the operating status parameters of the air-conditioning and the remote control function of the air-conditioner. The system architecture diagram is as follows:

Program features:

The scheme follows the principles of complete functions, stability and reliability, and cost saving, and comprehensively considers construction, maintenance and operation factors, and has the following characteristics:

1. Real-time support of the overall ambient temperature in the area: scientific management of air-conditioning operation to ensure that environmentally friendly and comfortable air-conditioning room environment is provided;

2. Powerful centralized management and automatic control function: the software function of the centralized control system of central air conditioning is very comprehensive;

3. Stable and reliable operation: Zonghengtong central air conditioning remote intelligent controller and monitoring platform software have mature technology, good compatibility, and stable and reliable overall operation;

4. Detailed data statistics and report analysis function: the system supports hierarchical alarm setting, real-time query and management of operation and maintenance logs and reports;

5. Significant energy-saving effect: greatly improve the actual use efficiency, thereby effectively reducing the waste of electricity and saving the overall operating cost of users;

6. Support hybrid networking of multiple communication methods: effectively solve the problem that the on-site environment is complex and inconvenient for implementation;

7. Strong expansion ability: the system has strong expansion ability, which can be easily realized when the number of air conditioners increases or when an appropriate amount of other environmental sensing equipment needs to be connected, so as to meet the future development requirements;

8. Convenient management and maintenance, efficient management level: the remote control function greatly reduces labor intensity, reduces air conditioning operation and maintenance personnel, and improves the management level.

Application value

1. Centralized and unified automatic control, effectively avoiding the situation that people have left but forget to turn off the air conditioner or the air conditioner is abnormally turned on;

2. Real-time detection of the operating status of the air conditioner (temperature, air volume, etc.), scientific scheduling, reasonable use of the air conditioner to save electricity;

3. Automatic alarm function of air conditioner abnormality, find problems in advance, and safely maintain and manage air conditioners;

4. The data analysis function allows managers to know the electricity consumption of air conditioning and optimize the scheduling reasonably.
