Embodiment Construction

[0017] The method for ensuring the air volume of the fresh air system of the present invention is as attached figure 1 shown, including the following steps:

[0018] S01. The manufacturer debugs the fresh air equipment according to the air duct of the standard specification, sets the frequency F1 of the fan of the fresh air equipment according to the air volume, and obtains the reference power Pa of the fresh air system corresponding to the air duct of the standard specification;

[0019] S02. Install fresh air equipment and air ducts according to the actual conditions of the installation site, and obtain the benchmark power Pb of the fresh air system after installation;

[0020] S03. Adjust the fan frequency of the fresh air system after installation according to a reference power change rate ΔP, where the reference power change rate ΔP=(Pb−Pa)×100%÷Pa.

[0021] Further, the method for obtaining the reference power by the fresh air system in steps S01 and S02 includes the fo...

Abstract

The invention relates to a fresh air system. According to a method for guaranteeing the air volume of the fresh air system, the draught fan frequency of the installed fresh air system is adjusted by calculating the change rate of the standard power of the installed fresh air system relative to the factory standard power, the problem that after the fresh air system cannot be installed according to the pipeline standard provided by a manufacturer, the air volume does not reach the standard or exceeds the standard is solved, and the method is suitable for the fresh air system.

Description

technical field [0001] The invention relates to a fresh air system, in particular to a method for ensuring the air volume of the fresh air system. Background technique [0002] The factors affecting the air volume of the fresh air system not only depend on the power of the fan, but also are closely related to the pipes of the fresh air system. For the fresh air equipment that leaves the factory, the manufacturer will carry out supporting tests with the fresh air equipment according to the standard specifications of the pipes, and the air volume of the fresh air equipment according to the air volume standard. The fan frequency is set. [0003] The manufacturer will provide the standard specifications of the pipes installed in the fresh air system, including aperture and length. In order to make the air volume of the fresh air system after installation meet the standard, it is necessary to install according to the pipe standards provided by the manufacturer. However, in the ac...
