Key points of selection and installation of fresh air booster cabinet
Key points of selection and installation of fresh air booster cabinet(A) How to choose the fresh air booster cabinetThe selection of a fresh air booster cabinet is very important and is directly related to the subsequent use effect and the improvement of air quality. First of all, the amount of fresh air required should be determined according to the size of the space. In general, the amount of fresh air required can be estimated by calculating the volume of the space combined with the recommended number of air changes. For example, for an ordinary family home, the number of air changes per hour is usually about 0.75-1. If the area of a room is 20 square meters and the height is 3 meters, then the volume of the room is 20×3 = 60 cubic meters. According to the number of air changes of 0.8 times per hour, the required fresh air volume is 60×0.8 = 48 cubic meters/hour. In addition to space size, usage requirements are also key factors. If it is in hospitals, laboratories, and other places with high air quality requirements, it is necessary to choose a fresh air booster cabinet equipped with high-efficiency filters and strong purification capacity to ensure that it can effectively filter out bacteria, viruses, and other microorganisms and small particles. In general commercial places or families, if the air quality in the area is good, there is a certain demand for formaldehyde, odor, etc., you can choose a fresh air pressurizer with activated carbon adsorption function. There are also budget and brand factors to consider. Different brands of fresh air booster cabinets differ in performance, quality, and price. In the case of a limited budget, you can make more comparisons in the market and choose cost-effective products. At the same time, we should choose well-known brands and products with good reputations, so that product quality and after-sales service are more guaranteed. (2) Installation precautions The installation of a fresh air booster cabinet is an important link to ensure its normal operation and best results, and the following aspects need to be paid attention to. The choice of installation location is critical. To reduce the impact of noise on indoor personnel, the fresh air booster cabinet should be installed as far away from the living area as possible, such as the ceiling of the balcony, kitchen, and bathroom. These locations can not only reduce noise interference but also save indoor space without affecting the beauty of the room. Before installation, ensure that the installation location has enough space for later maintenance and maintenance, such as replacing the filter, cleaning the pipeline, etc. In general, at least 50 cm of space should be reserved around the fresh air booster cabinet as the maintenance area, and the maintenance port should be set up above or on the side. Plumbing connections cannot be ignored. The connection between the fresh air booster cabinet and the ventilation duct must be tight and firm to prevent the occurrence of air leakage. When connecting pipes, appropriate sealing materials, such as rubber seals, sealants, etc. should be used to ensure the tightness of the joints. At the same time, pay attention to the direction and layout of the pipeline, minimize the bending and length of the pipeline, reduce the wind resistance, and improve the transportation efficiency of fresh air. If the pipe needs to pass through walls or floors, take protective measures to avoid damage to the structure of the building. In addition, it is also necessary to consider the location of the fresh air intake and exhaust vents. The fresh air outlet should be set in a place where the outdoor air is fresh and pollution-free, away from pollution sources, such as kitchen fume discharge outlets, garbage stations, etc. The exhaust outlet should be kept at a certain distance from the intake outlet, and it is generally recommended that the distance be more than 1.5 meters to avoid the discharged dirty air being re-inhaled. During the installation process, the height and Angle of the intake and exhaust vents can also be reasonably adjusted according to the actual situation to obtain better ventilation effects. |
