Problems solved by technology

However, the current fresh air control system simply introduces outdoor air to achieve the purpose of replacing indoor air, which cannot provide a scientific air supply volume, nor can it ensure that the concentration of indoor pollutants meets the target requirements
There are also relatively advanced fresh air systems that use real-time monitoring of indoor pollutant concentration to increase or decrease fresh air volume, but this method requires real-time monitoring, consumes a lot of energy, and has too high requirements for monitoring instruments, and cannot be considered scientifically. Requirements for Comprehensive Removal of Air Pollutants

Abstract

The invention relates to an intelligent regulating system for the air quality and temperature in a closed room and a use method of the intelligent regulating system. The system comprises a fresh air quality pretreatment unit, an indoor detection unit, an indoor fresh air control unit and an intelligent control unit. The fresh air quality pretreatment unit comprises a particulate filter and a small electric dust removal system. The indoor detection unit comprises a CO2, formaldehyde, temperature and infrared intensity detector. The indoor fresh air control unit comprises a fresh air flow and temperature controller. The intelligent control unit comprises a data processor and an intelligent control terminal. Indoor personnel inputs various parameters of the room into the intelligent control terminal, the data processor works out the required fresh air flow and temperature meeting the requirements of the indoor air quality and temperature through a preset model algorithm according to the input parameters and the detection result of the detector, and the fresh air flow and the temperature are fed back to the control unit for execution. The system has three working states and can be switched among the three working states according to different operating time lengths so as to achieve the purposes of adjusting and keeping the indoor air quality and temperature.

Description

technical field [0001] The invention belongs to the field of indoor air purification and temperature regulation, and in particular relates to an air quality and temperature intelligent regulation system and a use method in a closed room. Background technique [0002] Air is an indispensable element for human survival. In recent years, air pollution has become more and more serious, and people's attention to this issue has also been increasing. Due to the continuous decline of outdoor air quality, for indoor spaces, the methods of improving indoor air by using primitive means such as opening windows for ventilation will directly introduce various pollutants in the outdoor air into the room, so more and more indoor spaces in modern cities use Closed design. But at the same time, due to the small indoor space, adopting a closed design will lead to poor air circulation and diffusion capabilities, which will easily lead to an increase in the concentration of new indoor pollutant...
