      Analyze what benefits the fresh air system brings to people
      2019-09-07 14:49 NEWS

      The fresh air system is the product of many household ventilation systems in the past two years. Under the condition that the outside air is getting worse, more and more families choose to install a "ventilation fan" for the home. Of course, the natural thing here is not unusual. The ventilating fan is a household fresh air system. This type of system can be used to filter the air, and the air that is introduced into the home can be effectively filtered. The wind and soundless method can be used to transform the home environment. The relevant staff of Haotian explained to everyone. Regarding the fan power problem of the home fresh air system, the power of the fan determines the technical parameters such as labor efficiency and air exchange rate of the fresh air system.

      The basic theory of the fresh air system is that the concentration of space carbon dioxide is regulated at 0.1%, and the amount of fresh air flow of 30 cubic meters per hour is required. The timing is to track the amount of carbon dioxide in the human body. Generally speaking, the carbon dioxide exhaled by the human body. It accounts for 4%~5% of the exhaled gas, so after measuring the content, you can measure how long it can reach the indoor air.

      What is the calculation of the new air volume? The calculation method of the charter in GB/T18883 can be applied to the box form, the difference method, the steady state method, the average method, the regression method, etc., but in the practice of guessing, the nonlinear regression is used. The calculation is a fast and contrasting method.

      The fan power difference and quality of the brand-new brand's fresh air system are different. It is natural to choose a host with small power, large air volume and low noise. Therefore, if the same air volume is selected, the low power can be selected to reach the energy saving effect.

      The above is the environment about whether the fan power of the fresh air system is critical. After explaining, you should also know that the appropriate fan power can have a great energy saving effect.
