Description

Environmental air flow management system with non-cold source and/or high pollution source
Technical Field
The invention relates to the field of environmental parameter control of living environments of people or working environments of people, in particular to an environmental air flow management system with non-cold sources and/or high pollution sources.
Background
Under the environment with non-temperature sources or high pollution sources such as stoves, hot pots, various industrial equipment and the like, people often bear high-temperature baking and pollutant attack, and the most typical scene is a kitchen in a residential building in China, and meanwhile, the problems of poor indoor air quality and a hot environment exist. The eating habit of Chinese meal determines the cooking mode adopted by people, mainly frying, and the edible oil and food can be cracked at high temperature, so that a large amount of harmful oil smoke and combustion waste gas are generated. There are studies showing that the harmful substances in kitchen fumes, which are mainly aldehydes, ketones, hydrocarbons, fatty acids, alcohols, aromatic compounds, lactones, heterocyclic compounds, etc., have lung toxicity, immune toxicity, genetic toxicity and potential carcinogenicity, are more than 300. In addition, natural gas burns incompletely and generates a great amount of waste gas such as carbon monoxide, which also causes harm to human bodies.
Clinical study data in the medical community indicate that: the average person can breathe about 18 times per minute, the inhaled air quantity is about 1500 milliliters, and when the kitchen works, the breathing frequency can reach 25 times per minute, and the breathing air quantity is about 2000 milliliters. It was estimated that up to 120000 ml of breathing air was available in the kitchen for 1 hour. In recent years, the world health organization keeps on releasing, and harmful substances in the oil smoke can cause lung cancer (lung adenocarcinoma), various respiratory diseases and reduce human immunity, and in a dryness-heat environment, the oil smoke can be adsorbed on the skin of the face, so that the skin is dull and dull, and aging is accelerated.
In addition to low air quality, the thermal environment is also a great hazard to the human body. In hot climates such as summer, the outdoor temperature can reach 30 degrees sometimes, and the kitchen temperature can reach more than 40 ℃ sometimes even, and people can have symptoms such as dizziness, debilitation, unsmooth breathing and the like in the stay time process under hot environment, and extreme conditions such as heatstroke and coma can appear in severe cases.
In order to solve the problem of air pollution, the main mode of removing kitchen pollutants in urban residential kitchens is to arrange a smoke exhaust ventilator, and exhaust the smoke exhaust ventilator through an exhaust duct, but the range of coverage of the smoke exhaust ventilator is limited although the smoke exhaust ventilator can exhaust certain harmful gases, and part of harmful gases are difficult to leak to a person staying area, even accumulate on the height of the mouth and nose of the person, and cannot achieve ideal air quality.
In order to solve the problem of thermal environment, the existing solution is to install air conditioning equipment in a kitchen, however, greasy dirt and oil smoke in the kitchen are very easy to cause pollution and damage of components in the air conditioner, and the service life of the air conditioning equipment is greatly shortened.
Not only in a kitchen, but also in a hot pot store, a barbecue store and other scenes, people often have sweat flow down back due to the baking of a high temperature source when dining, even feel lack of oxygen and unsmooth breathing, and harmful substances brought by the hot pot and barbecue also endanger the health of people.
In industrial environments with heating furnaces, boilers, heating equipment or pollutant emissions during operation, workers near non-cold sources or high pollution sources often experience problems such as overheating, insufficient fresh air, poor air quality, uncomfortable feeling, etc.
It is appreciated that there is a need for a system and method for managing and organizing ambient air flow in environments with non-cold sources and/or high pollution sources that helps people get rid of the high temperatures and dirty air and creates a healthy, comfortable, pleasant environment.

The delta is a calculation influence factor, which specifically can be calculated according to a scene setting mode selected by a person, or can be other calculation influence factors, and the calculated wind speed and angle are not identical under the influence of different calculation influence factors.
Wherein, the scene setting mode is an important calculation influence factor, and the setting module can provide a plurality of scene modes for people to select: for example, in the ultra-large air volume mode, the rapid ventilation mode, the medium speed mode, the low speed soft mode and the like, under the condition that different scene modes are selected, the air speed and the angle calculated by the air speed calculating unit and the angle calculating unit are different in the different scene modes, so that the air speed of the air reaching the face of the person is proper, the requirements of the different scene modes are met, for example, the air speed is not too large, the person generates strong blowing feeling, and is not too small, and the person feels uncomfortable.
Referring to fig. 5, under the management of the non-cold ambient air flow management system, the air flow to be managed generally forms the following air flow paths: the air flow flows out from the air supply opening of the fresh air subsystem, directly or substantially directly blows to the forehead of a human body, downwards flows along the human body to take away part of heat generated by the human body, flows near the non-cold source and is discharged through the suction opening of the air exhaust subsystem, and the amount of fresh air fed by the fresh air subsystem is not more than the air quantity discharged by the air exhaust subsystem, so that the indoor micro negative pressure state is maintained.

However, the information fed back by the human physiological parameter monitoring module should not be prioritized over the setting module in all cases, and in some cases, although it is determined that a certain parameter of the human body deviates from a normal value, the human body feel is not so bad, so that it is desirable to select the profile by selecting itself. In some cases, the human body can feel that the air supply mode is soft, but the air quality monitoring subsystem judges that the air quality is bad, and the priority of feedback information of the subsystem is also improved.
The logic judging module is used for judging the priority of the information fed back by the setting module, the human physiological parameter monitoring subsystem and the air quality monitoring subsystem and used for calculation by the wind speed calculating module, the angle calculating module and the refrigerating subsystem.
The logic judgment module is provided with an initial judgment logic which can record various habits of a user in use and continuously perform self-learning so as to find the optimal priority control logic.
