Automatic control device of building air conditioning system

Abstract

The invention relates to an automatic control device of a building air conditioning system. The automatic control device of the building air conditioning system comprises a plurality of sensors, a plurality of controllers, a plurality of valve actuators, a plurality of interlock detecting devices and a server, wherein each controller can be connected with the sensors, the valve actuators and the interlock detecting devices at the same time, and the server is connected with the controllers. The automatic control device of the building air conditioning system has the advantages that indoor constant temperature and humidity, zone control and automatic alarm are achieved and ideal positive or negative pressure is obtained.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and relates to an automatic control device for a building air-conditioning system. Background technique [0002] Today, with the rapid development of information technology, the hospital's comprehensive information management and release system is playing an increasingly important role, and the integration of intelligent control systems has become an important part of the hospital's comprehensive information management system, especially the hospital's air-conditioning system. Because it involves the safety of patients in the hospital, its automatic control is particularly important, but the current hospital air-conditioning system has the following problems: [0003] 1. Air quality cannot be guaranteed: Since the hospital is a place where various bacteria and pathogens meet, the requirements for air quality are very high, including fresh air volume, ventilation frequency, cleanlin...

AI Technical Summary

Problems solved by technology

[0003] 1. The air quality cannot be guaranteed: Since the hospital is a place where various bacteria and pathogens meet, the air quality requirements are very high, including fresh air volume, ventilation times, cleanliness, etc.

However, the general air-conditioning system cannot automatically complete this part of the work. If it is adjusted only by manpower, it will be a waste of manpower and imprecise.

[0004] 2. Unable to achieve constant temperature and humidity: Nowadays, hospitals generally adopt the principle of humidity priority in temperature and humidity control, because after research, when the relative humidity is 50%, the bacteria die after floating for 10 minutes, but when the relative humidity is high or low, Most of the bacteria were still alive after 2 hours

Therefore, the hospital will maintain a constant temperature and humidity state of 50% relative humidity, but ordinary air-conditioning units cannot achieve this part of accurate monitoring and control

[0005] 3. Zoning control cannot be realized: due to the use time of each department of the hospital, and the requirements for temperature, humidity and cleanliness are different, the air conditioning system also requires zoning setting and control

This is also difficult to achieve with ordinary air-conditioning units.

[0006] 4. Unable to realize fault alarm: Since the air-conditioning unit cannot automatically alarm, many faults occur but cannot be dealt with in time, which affects daily use

[0007] 5. Unable to achieve positive and negative pressure difference in the hospital: Some places in the hospital have positive or negative pressure requirements, such as operating rooms and ICUs generally have positive pressure requirements, while infectious disease areas require negative pressure, only building automation systems are used In order to ensure the dynamic change of pressure
