Description

Intelligent circulation air conditioning positive and negative pressure system and method in closed multi-space areas

The present invention relates to a system and method for intelligent circulation air conditioning positive and negative pressure in closed multi-space areas, and in particular to a system and method for intelligent circulation air conditioning positive and negative pressure that senses the air quality in a closed space and enables each space to independently intake and exhaust air.

According to the report, the COVID-19 outbreak began at the end of 2019. COVID-19 is a respiratory disease. In recent years, the concept of epidemic prevention has become a more important issue than air quality. The impact of poor air quality caused by PM2.5 and other suspended factors is not yet obvious, but infection with COVID-19 will directly threaten the health of patients, and there are many sequelae. One of the transmission routes of COVID-19 is aerosolization. Glue, attached to suspended aerosols and dispersed in the space, especially in closed air-conditioned spaces where suspended dispersion can last up to 20 minutes. Early epidemic prevention policies required social distance between indoors and outdoors to avoid infection, but learning and working behaviors require staying in closed spaces for a long time. The extended time span greatly increases the probability of infection. The key to reducing infection lies in effective ventilation control, reducing the concentration of aerosols in the air to prevent virus attachment.

Therefore, it is very important to control the indoor air quality. There are many ways to solve it. The first is to separate cabins and flow, so that each space has independent air intake and exhaust to ensure that there is no possibility of cross infection. This is horizontal control. The second is layered control, which controls the exhaust return flow of the central vertical shaft of each floor so that the air on each floor does not communicate with each other. This is vertical control. The third is flow distribution and direction distribution, which configures the air flow direction and flow rate according to the air cleanliness requirements.

The conventional air conditioning system only blows cold air into the room after the heat exchange is completed, but does not strengthen the air circulation in the room, creating conditions for the virus to stay. In addition, each space does not have independent air intake and exhaust, which may lead to cross infection. There are many closed spaces in office buildings and quarantine hotels, and the air needs to be circulated and regulated to prevent the harm of viruses, bacteria, dust, and chemical substances.

Therefore, the inventor of this invention took this into consideration and came up with the idea of invention. He then designed it based on his years of experience, conducted many discussions and conducted sample tests, and made many revisions and improvements before launching this invention.

The air conditioner is provided with a main controller for controlling and connected to a blower motor for delivering air, and the blower motor is connected to the air intake system; the air intake system is connected to the space and has a converter, which is a three-way two-phase converter that can be switched freely and allows air to enter and be discharged from the designated space, and one end of the converter is connected to a purifier, which has a filtering function and can sterilize the air by UV light irradiation. The air intake system can be used to send air into the space so that the space generates positive pressure to allow air circulation, and the converter inlet is connected to another air intake system or the blower motor by using the converter.
