Background of the programme

According to the data of the National Bureau of Statistics, since 2009, the use of air conditioning in the country is accelerating year by year, a major reason is that with the global warming, the average temperature in most parts of China in summer is getting higher and higher, and the duration of high temperature weather is getting longer and longer, it can be said that air conditioning has gradually become an indispensable household appliance in our production and life. Although the state has issued a series of favorable policies to promote the development of the air-conditioning industry, the energy efficiency ratio of ordinary air-conditioning has been continuously improved, and it can be said that air-conditioning is becoming more and more energy-saving, but there is no doubt that air-conditioning is still the most power-consuming electrical equipment in our lives. Through statistics, it is found that the electricity cost of air conditioning is not only caused by the high power of the air conditioner itself, but also an important reason is that the irrational use of air conditioning and the lack of management of air conditioning have caused a lot of waste of power resources, as follows:

1. Unreasonable use of air conditioner: the setting of air conditioning temperature is unreasonable (usually the operating temperature of air conditioning is set artificially, resulting in serious waste of energy consumption in air conditioning refrigeration/heating); After the air conditioner is turned on, the use scenario is not closed (the air conditioner is run without closing the door and opening the window, resulting in poor cooling/heating effect, and the air conditioner compressor is always in a high-power working state).

2. Lack of unified and standardized management of air conditioning: For air conditioning scattered in different areas, air conditioning management personnel cannot accurately and timely grasp whether the air conditioner is arbitrarily turned on, whether the operation mode of the air conditioner is correct, whether the air conditioner is faulty and running (such as the refrigeration effect is seriously low and still forced to start operation) and other information, once the above situation occurs, it will undoubtedly cause a huge waste of resources.

Solution introduction

Based on more than 20 years of project experience accumulation in the field of centralized management of air conditioners, Zonghengtong proposes a comprehensive solution for high efficiency and energy saving of split air conditioners, which uses the 5th generation intelligent energy-saving air conditioning controller independently developed by Zonghengtong to perfectly solve the management problem that ordinary air conditioners (all air conditioners that support infrared control, including: cabinets, hang-ups, ceiling machines, etc.) have no communication interface and cannot carry out remote control and status monitoring of these air conditioners; At the same time, the air-conditioning energy-saving strategy accumulated on the basis of years of centralized management of air-conditioning is applied to the air-conditioning energy-saving management platform, and the unified standardized management and intelligent energy-saving control of air conditioning are perfectly realized through the combination of air-conditioning intelligent controller (hardware) + air-conditioning energy-saving management platform (software). The system topology diagram is as follows:

Program features

The remote centralized control and energy-saving management solution for Zonghengtong air conditioning is a comprehensive design that combines the concepts of centralized air conditioning management and automatic energy-saving scheduling. The solution follows the principles of system stability, reliability, complete functions, simple management, and cost savings, and comprehensively considers the construction and subsequent equipment maintenance convenience of the air conditioning management system project. At the same time, it also includes system support for subsequent air conditioning changes (such as adding new air conditioners to the system, replacing old air conditioners, etc.). The solution has the following characteristics:
1. Centralized control of all air conditioners: supports remote unified control of any brand of air conditioner (infrared signal control type);
2. Real time monitoring of all air conditioners: real-time collection of on/off status, operating mode, and operating parameter information of air conditioners;

3. Remote management of all air conditioners: support manual remote control of all air conditioners on/off, operating parameter setting, air conditioner locking/unlocking and other functions;

4. The system automatically controls the air conditioner: the air conditioning management software automatically schedules the air conditioner to turn on/off at a regular time, automatically controls the air conditioner according to the ambient temperature, and automatically starts/closes the air conditioner according to the set conditions after the abnormal power failure calls.

5. Support intelligent linkage control of air conditioning: the air conditioning management system can automatically control the air conditioner through preset trigger conditions such as light sensor control, human body presence sensing, and ambient temperature detection;

6. Support multi-level authority management: The air-conditioning management system supports multi-level authority management, sub-regional management, and authority management based on user groups for air conditioners.

7. Real-time control of air conditioning electricity information: real-time statistics of air conditioning power distribution management information, air conditioning power consumption, electricity cost and other information;

8. Air conditioning power management function: support the power supply management of air conditioner, and realize remote power on-off control of air conditioner;

9. Support air-conditioning electricity quota management: The air-conditioning management system supports the air-conditioning electricity quota management function, which can carry out electricity fee management, prepayment fee management, recharge management and other functions for air-conditioning electricity.
