Background of the programme

After entering the 21st century, China's economy has developed rapidly, and the construction industry has continued to develop steadily, in order to meet the needs of urban development, countless high-rise office buildings have risen, these high-end office buildings are no longer pursuing the development cost of the lower the better, but the development of truly people-oriented, high comfort, high-quality commercial buildings, to ensure the comfort of office buildings a core system is the office air conditioning system.

Office air conditioning system has brought us a comfortable working environment, we enjoy the modern air conditioning technology to bring us a high-quality indoor environment at the same time, we are also constantly thinking about how to reduce the use of air conditioning system energy consumption problem, as early as August 2006, the General Office of the State Council has issued a decision >> << the State Council on strengthening energy conservationIn order to actively respond to the national policy of energy conservation and environmental protection, the intelligent energy-saving centralized control scheme of office air conditioning came into being.

Overview of the scenario

As we all know, high-end office buildings will use the central air-conditioning system, but the scheduling of the central air-conditioning system is managed by the building's property management, and each company in the building cannot remotely view and manage the air conditioning in its own office area; At the same time, in order to meet their own needs, many companies have also installed ordinary air conditioners in their offices. In addition, for the early construction of many office buildings do not have a central air-conditioning system, and some central air-conditioning coverage is incomplete, so it is normal for a company to use central air-conditioning and ordinary air-conditioning at the same time. It has the following characteristics:

1. The implementation of the project is convenient and beautiful, and the centralized management and energy-saving control of the air conditioner can be realized without disassembling the air conditioner or damaging the air conditioning structure.
2. Unified management of all air conditioners, and at the same time, ordinary air conditioners and central air conditioners are included in the same management platform to realize the centralized management of all air conditioners.
3. According to the on-site flexible networking, the networking mode of combining wired networking (network cable connection) and wireless networking (WIFI, Lora, etc.) is used.
4. Digitalization of air-conditioning management, real-time display and statistics of air-conditioning operation parameters, electricity consumption and other parameters of air-conditioning management system, so as to realize air-conditioning visualization and numerical energy-saving management.

Schematic design

Usually there are different types of air conditioners used in different areas of a company, the common situations are: central air conditioning in public areas (e.g., hall, conference room), small offices or special areas use ordinary air conditioning. The first problem solved by the intelligent energy-saving centralized control scheme of Zonghengtong office air conditioner is that the air conditioning system is connected to the central air conditioner and ordinary air conditioner at the same time. Another very important factor is to solve the problem of difficult implementation of air conditioning projects, and the feasibility of project implementation, the convenience of air conditioning controller installation and the overall aesthetics of the project must be considered at the same time. Therefore, in the scheme design stage, our company will select the appropriate air-conditioning controller (to meet the on-site networking needs) based on the on-site air-conditioning type, air-conditioning installation location, and on-site weak current line conditions, so as to realize the all-round monitoring and management of air-conditioning control based on automatic control and supplemented by manual control, and the system diagram is as follows:

Program features:

Whether it is a 5A-level office building that uses central air conditioning, or an old office building that uses ordinary air conditioning, or an office building that has a mix of central air conditioning and ordinary air conditioning, the intelligent energy-saving control system of Zonghengtong air conditioning can remotely monitor and manage these different types, different brands and any type of air conditioner, with the following characteristics:

1. Unified system: any type of air conditioner (mixed with central air conditioning and ordinary air conditioning) is centralized on the same platform for centralized management.

2. Independent control: All air conditioners in the system support one-to-one independent remote control (remote switching, setting operating parameters, etc.) functions.

3. Flexible networking: According to the actual situation on site, the product selection and the most suitable networking mode can be selected, and the hybrid networking method can be adopted.

4. Flexible management: all air conditioners in the system support the combination of automatic management and manual control.

5. Offline automatic control: the air conditioning controller can schedule the air conditioning operation offline, start the air conditioner automatically when calling in, and automatically adjust the operating temperature of the air conditioner.

6. One-key management: The system supports the "one-key management" function of all networked air conditioners, and the management interface is intuitive, simple and convenient.

7. Alarm notification: The system monitors the operation status and operating parameter information of the air conditioner in real time, and sends an alarm message immediately when it detects an abnormality.

8. Data report: The system collects all the operating data of the air conditioner in real time, automatically stores and generates data reports, and realizes the data management of the air conditioner.

Application value

1. Real-time monitoring of air conditioners: real-time view of all air conditioner opening status, operating temperature, ambient temperature and other information, and grasp the operation status of air conditioners in real time.

2. Remote management of air conditioning: one-to-one control of central air conditioning or ordinary air conditioning in each office area, and the system can automatically control all air conditioners.

3. Automatic management of air conditioners: The system supports the "one-key management" function for all air conditioners to reduce the operation difficulty and work intensity of air conditioning management personnel.

4. Intelligent management of air conditioning: the system automatically detects the indoor temperature and personnel flow in the office area, automatically adjusts the operating parameters of the air conditioner to ensure the comfort of the air conditioned room, and supports functions such as "no one automatically turns off the air conditioner".

5. Air conditioning safety management: automatically detect abnormal conditions such as line overload, undervoltage, and leakage, and give real-time alarms to information systems such as abnormal situations and air conditioning failures, and send alarm notification information to the outside world.

6. Data of air conditioning operation and maintenance: real-time recording of air conditioning opening status, operating parameters, operating time, power consumption and other information to achieve transparent and data management of air conditioning use.
