An air conditioner unit/device controller and system capable of controlling indoor air quality

Abstract

The invention provides an air conditioner unit / device controller capable of controlling quality of indoor air, and a system. The controller comprises a sensor set, an analog-digital converter and a single-chip microcomputer, wherein the sensor set is composed of sensors arranged at different indoor positions, the analog-digital converter is connected with the signal output end of the sensor set, the single-chip microcomputer is connected to the signal output end of the analog-digital converter, the signal output end of the single-chip microcomputer is connected with the signal input end of a central computer, and the display signal output end of the single-chip microcomputer is connected with an LED display screen and an LCD display screen. The control system comprises a plurality of draught fan coil pipe air conditioner / air conditioner device controllers which can control the quality of indoor air, wherein the signal output ends of the draught fan coil pipe air conditioner / air conditioner device controllers are connected with the signal input end of the central computer, the signal output end of the central computer is connected with the signal input ends of a tail end air conditioner device, a fresh air system, a draught fan coil pipe air conditioner, a light illumination device and an air purifier. According to the air conditioner unit / device controller and the system, the detection range of the air conditioner system can be directly expanded to the portion surrounding people, and therefore the accuracy of control over an air conditioner is greatly improved, and the range of control over the air conditioner is greatly enlarged.

Description

technical field [0001] The invention relates to an air conditioner controller. In particular, it relates to an air conditioner unit / device controller and system capable of controlling indoor air quality. Background technique [0002] With the continuous improvement of people's living standards, people have higher and higher requirements for the air environment of their residences. These requirements include requirements for thermal and humidity comfort, safety and health requirements, etc. Needless to say, heat and humidity comfort, in terms of safety and health, due to the use of decoration materials, there will inevitably be many harmful gas substances in rooms that have not been operated for a long time, among which formaldehyde gas is the most harmful and well-known. It is easy to induce nasopharyngeal cancer, sinus cancer, leukemia and other diseases, and seriously endangers human health. In order to timely detect the specific values ​​of relevant parameters in indoor...

AI Technical Summary

Problems solved by technology

[0003] 1. Single measurement parameter

Due to various reasons, we often see electronic instruments that measure temperature and humidity or the content of various single gases on the market, but rarely see instruments that fully integrate the monitoring of various parameters that affect the indoor air environment.

Therefore, in order to fully understand the indoor air quality we live in, we have to use a variety of instruments to measure separately, which is costly and time-consuming

[0004] 2. Measurement Space Constraints

Most of the existing air quality testing instruments are designed with a good air permeability shell, and use air convection to obtain the measurement results by analyzing the relevant parameters of the air flowing through the testing instrument, but most of the instruments are fixed on the wall Or a certain corner of the room, which makes the results measured by these instruments only reflect the air quality in a small part of the space where the monitoring instrument is located. It is difficult to obtain the air environment parameter distribution in the entire room of the house from a single measurement

[0005] 3. Results are not human enough

Most of the measurement results obtained by the existing air environment testing instruments are only scientific numerical indicators, and for those who do not have relevant professional knowledge, they do not know what range the values ​​of various parameters are suitable for, and there is no relevant standard database It is convenient for users to compare, and it is difficult to know the actual quality of the air environment just by looking at the data results

[0006] 4. Single function

Another example is the existing air-conditioning temperature controller, which has simple temperature measurement and control functions. Accurate, and there is no measurement function for indoor air pollutants, let alone adjust the operating parameters of the air system (device) according to the concentration of pollutants
