Abstract

A configuration method and structure for applying total external air to adjust the pressure in the internal area of a building. An isolation area and an entrance and exit are planned inside the building, and an air pressure isolation channel is planned between the entrance and exit and an outdoor environment so that the air pressure isolation channel is relative Compared with the isolated area and the outdoor environment, it is a positive pressure environment. Therefore, it is completely avoided that the unsterilized and filtered air outside the building will not enter the isolation area.

Description

The configuration method and structure of using total external air to adjust the pressure in the internal area of the building

The present invention is related to the configuration method and structure of the internal area pressure of the building, especially a configuration method and structure used to adjust the pressure of the internal area of the building using total external air.

Isolation wards in hospitals are usually set up independently in an isolation area separated from general wards, and the air pressure in the isolation area is also different from the general ward area. Generally, the ward for isolating infectious disease patients is set as a negative pressure isolation ward. The negative pressure isolation ward is equipped with a dedicated air-conditioning system to separate it from other air-conditioning systems in the hospital. There are two doors in the negative pressure isolation ward, and personnel cannot open both at the same time. The door keeps the indoor air as a negative pressure environment to avoid air cross-infection.

However, the hospital itself cannot avoid the inflow of outside air. As a result, the bacteria in the outdoor ambient air may still enter the building and penetrate into the negative pressure isolation ward, increasing the risk of re-infection of patients, so it is still not perfect.

Based on the above-mentioned deficiencies, the purpose of the present invention is to provide a configuration method and structure that uses total external air to adjust the pressure in the internal area of a building, and performs area protection to maintain the air cleanliness of the indoor environment.

Based on the above objective, the present invention provides a configuration method for adjusting the pressure in the internal area of a building using total external air, which includes the following steps: selecting the interior of a building as an isolated area, and the isolated area has an entrance and exit; and planning an air pressure isolation The channel is between the entrance and exit and an outdoor environment, and the air pressure of the air pressure isolation channel is adjusted to make the air pressure isolation channel a positive pressure environment compared to the isolation area and the outdoor environment.

In addition, the present invention also provides a structural configuration of the internal area of a building using a method for adjusting the pressure of the internal area of a building by applying total external air. Between the entrance and exit and an outdoor environment outside the building, the air pressure of the air pressure isolation channel is a positive pressure environment compared to the isolation area and the outdoor environment.

Wherein, the isolation area is divided into at least one isolation ward and at least one personnel passage, and the isolation wards are in a negative pressure environment relative to the personnel passage.

In this way, the unsterilized and filtered air outside the building will not enter the building, which fully prevents the isolation ward from flowing into the contaminated air.

Figure 2 is a schematic diagram of the configuration structure of the isolation area inside the building of the present invention

In order to clearly illustrate the specific implementation, structure, and achieved effects of the present invention, the accompanying drawings are described as follows: Please refer to Figure 1, which illustrates a configuration method for applying total external air to adjust the pressure in the internal area of a building. It includes the following steps. First, a specific area inside the building is selected as an isolated area (step S1), and the isolated area is planned as Multiple isolation wards and one personnel passage (step S2), and install multiple one-to-one or a single one-to-many intelligent full external ventilation system in each isolation ward and each personnel passage (step S2) S3 and S4), and adjust the isolation room environment to negative pressure, and maintain the personnel passage environment to positive pressure (step S5). In addition, adjust the air pressure of the air pressure isolation channel 30 so that the air pressure isolation channel 30 is compared with The isolation area and the outdoor environment B are positive pressure environments.

Referring to FIG. 2, the present invention also provides a configuration structure that uses total external air to adjust the pressure in the internal area of a building, including an isolation area divided into a plurality of isolation wards 10 and a personnel passage 20, in each isolation ward 10 and Each of the personnel passages 20 is equipped with an intelligent total external ventilation system 11, wherein each of the isolation wards 10 is provided with an entrance 15 to communicate with the personnel passage 20, and the personnel passage 20 is provided with an entrance 25 for personnel to enter and exit the building . It is supplemented here that, in addition to providing two-way traffic, the aforementioned entrance and exit 15 can also be set as a one-way entrance or exit.

In this embodiment, each isolation ward 10 has an independent intelligent total external ventilation system 11 that is connected to the outside world, so that the air inside the isolation ward 10 will not communicate with the air in other areas of the building, and Before the air in the isolation ward 10 is exhausted to the outdoors, the smart total external air ventilation system 11 will sterilize and filter the indoor air before exhausting it to the outdoors to prevent the air in the isolation ward that may contain bacteria from being transmitted to the outdoors , Resulting in pollution of outdoor air.

Since the entrance and exit 25 are maintained at a positive pressure, the air outside the building can be prevented from entering the building from the entrance and exit. The intelligent total external air ventilation system 11 will introduce outdoor natural air into the isolation ward 10 and perform sterilization and filtration at the same time , Will not introduce the air inside the building A into the isolation ward 10. This setting can prevent the air that may be entrained with bacteria outside the building without being sterilized and filtered into the building A, avoiding the situation of cross infection.

Further, the intelligent total external air ventilation system 11 will detect the air pressure values inside and outside the isolation ward 10, maintain the isolation ward 10 in a negative pressure environment, and keep the personnel passage 20 relative to the isolation ward 10. It is a positive pressure environment, so that the air in the isolation ward 10 will not circulate to the personnel passage 20. When the personnel enters and exits the isolation area through the personnel passage entrance 25, it can also prevent the air pollution of the isolation ward 10 from entering the building interior A. Other areas.

In addition, it is also possible to plan an air pressure isolation channel 30 at the entrance of the building. When people enter the building A from the outdoor environment B, they must first pass through the air pressure isolation channel 30. The air pressure isolation channel 30 is the air pressure regulation area. The air pressure in the air pressure isolation channel 30 is a positive pressure environment relative to other areas of the building (ie, non-isolated areas) and the outdoor environment B environment, so that the air inside the building A and the outdoor environment B will not circulate mutually, preventing air pollution Enter A inside the building.
