Hole-opening method for measuring holes for testing performances of ventilation and air conditioning system

Abstract

The invention discloses a hole-opening method for measuring holes for testing performances of a ventilation and air conditioning system. The hole-opening method comprises the following steps: I, determining positions of measuring sections and the measuring holes: according to pre-designed test requirements of the ventilation and air conditioning system, determining quantity of to-be-tested test sections on a to-be-tested flue, the position of each test section as well as quantity of to-be-opened measuring holes in each test section and hole position of each measuring hole; II, opening and sealing measuring holes: respectively opening all measuring holes in the to-be-tested flue, and sealing each measuring hole as follows: 201, opening holes: drilling by adopting drilling equipment; 202, sealing the measuring holes: sealing processed and formed measuring holes by adopting a sealing part. The hole-opening method disclosed by the invention is simple in step, reasonable in design, convenient to realize, high in working efficiency, good in using effect and capable of simply, conveniently and quickly completing a hole-opening process of measuring holes of an air hose, and guaranteeing the performance test effects of the ventilation and air conditioning system.

Description
