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

technical field [0001] The invention belongs to the technical field of ventilation and air-conditioning system performance testing, and in particular relates to a method for opening a measurement hole for performance testing of a ventilation and air-conditioning system. Background technique [0002] The ventilation and air-conditioning system is composed of a ventilation system and an air-conditioning system. The ventilation system is composed of a supply and exhaust fan, air duct, air duct components, muffler, etc.; and the air-conditioning system is transported and distributed by air-conditioning cold and heat sources, air handlers, and air delivery pipes. And the automatic control and adjustment of the air conditioner to the indoor temperature, humidity, airflow speed and cleanliness.

Problems solved by technology

In recent years, the structure and materials of air ducts have become more scientific and diversified. In addition to traditional metal steel air ducts, non-metallic air ducts such as inorganic glass fiber reinforced plastics and U-PVC, and composite material air ducts such as aluminum foil polyurethane are also known for their unique characteristics. It has been widely used; in addition, in order to meet the requirements of energy-saving buildings, the surface of air ducts is mostly covered with heat-insulating structures. In addition, the space of multi-specialty pipelines on the construction site is staggered, and the difficulty of opening the measurement hole increases accordingly, and the construction of the opening of the measurement hole Quality requirements are also very strict
