Description

Technical Field

[0001] The invention belongs to the technical field of automatic control and management of central air conditioners, and relates to an energy-saving automatic control and management system for central air conditioners. Background Art

[0002] With the rapid development of the economy, central air-conditioning is becoming more and more popular in public buildings, and the burden of high energy consumption is also increasing. In addition, the central air-conditioning system is usually controlled as a whole building unit, which may not be able to meet the individual needs of different rooms or different users, resulting in some rooms being too cold, too hot, too humid or too dry, making the indoor comfort level poor. Therefore, it can be seen that energy-saving automatic control and management of central air-conditioning is of great significance.

[0003] At present, there are still a series of deficiencies in the existing technology for automatic control and management of central air-conditioning, which are specifically reflected in the following aspects: (1) In terms of automatic control, the existing central air-conditioning system is only controlled according to the temperature and humidity in the environment. The control basis is too single, which makes the adaptability and accuracy of temperature and humidity control low.

[0004] (2) In terms of user experience, the current central air-conditioning control system does not conduct targeted monitoring of the personnel situation and space status in the area where the air outlets of the target central air-conditioning are located, resulting in the inability to perform personalized temperature and humidity control, which may reduce the user's physical comfort.

[0005] (3) In terms of energy conservation, the current central air conditioning is controlled manually by the user, which is highly subjective and requires a certain level of energy-saving awareness from personnel. There is a possibility that the central air conditioning equipment will be forgotten to be turned off or the air conditioning will be left on for a long time when no one is at work. This cannot reduce unnecessary energy loss and results in a large amount of waste of electricity resources. Summary of the Invention
