Central air conditioner terminal device control system integrated with space information, and working method thereof

Abstract

The invention relates to a central air conditioner terminal device control system integrated with space information, and a working method thereof. The central air conditioner terminal device control system comprises a human-computer interface, a controller and air conditioner terminal devices. The system displays area spaces through the human-computer interface and presents data information fed back by the air conditioner terminal devices. The air conditioner terminal devices can be automatically displayed on the corresponding positions of figures representing buildings or specific floors, anda user is allowed to intuitively group the devices and conduct parameter adjusting on the air conditioner terminal devices in groups. Numerical distribution of environmental parameters on all positions of a certain area or space and change of distribution in time are displayed. The abnormity of sensors is found through the adjacent sensors, and abnormal data are substituted in necessity. The usercan intuitively record complaint information and summarize the complaint information at the adjacent positions to guide the air conditioner terminal devices to operate. According to the central air conditioner terminal device control system, the different air conditioner terminal devices at the different positions can further be automatically harmonized to conduct mutual support and cooperation,and thus oversupply of an air conditioner system is lowered, so that energy conservation is achieved.

Description

technical field [0001] The invention relates to a central air-conditioning terminal equipment control system and a working method that integrates spatial information. Background technique [0002] The central air-conditioning system is divided into two parts: the supply side and the demand side. The former mainly includes chillers, boilers, water pumps, cooling towers and other equipment. As the cold and heat source of the central air conditioner, it provides the central air conditioner with cold water for air conditioning or hot water for heating. The latter includes a number of air-conditioning terminal equipment such as air-conditioning boxes, fresh air boxes, fan coils, temperature and humidity sensors, etc., which are installed in different positions inside the building to keep the temperature, humidity and air cleanliness inside the building within the specified range Inside. The invention is aimed at the control of several air-conditioning terminal equipment in the ...

AI Technical Summary

Problems solved by technology

In the man-machine interface, this type of software relies more on the configuration engineer to pile up graphic elements, and the configuration software cannot "understand" the real meaning of these graphic elements, so in addition to displaying the specified graphic elements at the position specified by the configuration engineer , the configuration software has no more information to process and utilize to automatically provide more functions for engineers and users

The same situation exists in the aspect of control, causing the control system to only act according to the plan preset by the engineer

Due to the many factors that affect building control, the control scheme provided by engineers cannot cover all possible scenarios, and it is impossible to be flexible and efficient enough even for typical control scenarios
