Central air conditioning system energy-saving control method based on thermal imaging and big data technology

Abstract

The invention discloses a central air conditioning system energy-saving control method based on thermal imaging and big data technology. Aiming at solving the problem that an operation control method,applying a traditional form, over a central air conditioning system of functional buildings such as an airport terminal, a station waiting hall, a wharf, a convention and exhibition center and a multi-function hall has obvious defects, and aiming at meeting the requirements of the above similar buildings on the thermal comfort and air quality of the central air conditioning system and achieving the purposes of saving energy, and being green, comfortable and healthy, the control method can achieve the goal of carrying out small-area decentralized independent control over large-area integral areas in the buildings, and the intelligence level of system operation can be improved.

Description

technical field [0001] The invention relates to the field of HVAC, in particular to an energy-saving control method for a central air-conditioning system based on thermal imaging and big data technology. Background technique [0002] At present, most functional buildings such as airport terminals, station waiting halls, wharves, convention centers and multi-function halls have some common architectural features and air-conditioning system features: [0003] (1) The buildings are relatively tall, with a large flow of people and high density, and the operation time is long throughout the year, and the arrival and departure of personnel have time rules, etc.; [0004] (2) The peak load of the air-conditioning system is relatively large, and the air-conditioning system with full-air mixed ventilation and air supply from the nozzle jet or the top swirl air outlet is generally used. Multiple air-conditioning units are operated in parallel to control the indoor temperature and humi...

AI Technical Summary

Problems solved by technology

In view of the rules mentioned above, if the large-scale areas of functional buildings such as airport terminals, station waiting halls, wharfs, convention centers and multi-functional halls are the control objects, it is obviously not possible for the air conditioning system to be turned on, off and adjusted synchronously. Reasonable, it will lead to an increase in the load of the air conditioning system, the initial investment of the system, the increase of operating energy consumption and cost, etc.

In addition, fixed temperature and humidity parameters are set for the entire indoor area. For people who enter in different clothes, different regions (south or north, etc.), and different time periods (day or night), the thermal comfort is not good
