Ventilation system construction method

Abstract

The invention discloses a construction method of a ventilation system, which relates to the technical field of designing building ventilation, and solves the problem of prolonging the construction time caused by the difficulty in finding the location of air leakage in the prior art. The key points of the technical scheme include the following steps: A: ventilator , Installation and construction of refrigeration units and purification units; B: Construction of ventilation ducts: a. Duct transportation; b. Duct pairs; c. Horizontal duct installation; d. Riser installation; e. Duct insulation; f. Shock sensor installation; g. Air tightness test; h. For maintenance and completion, during construction, a vibration sensor is installed at the connection of the ventilation pipe. During the sealing test, if there is air leakage at the connection of the pipe, the vibration sensor will report an error through the control center, so that it can be completed in a short time. Find the location of the air leakage for maintenance within a short time, which greatly shortens the construction time.

Description

technical field [0001] The invention relates to the technical field of building ventilation, more specifically, it relates to a construction method of a ventilation system. Background technique [0002] With the gradual increase in building height and people's increasing requirements for building comfort, the requirements for building ventilation are also gradually increasing. The ventilation system cannot affect the heating and cooling in the building, and it is also necessary to ensure the building system. Air circulation. Generally speaking, the ventilation system of a building is mainly composed of ventilation ducts, which need to be installed during construction. [0003] In the existing construction process, after the construction is completed, the airtightness test of the ventilation duct is required. Once the ventilation duct leaks are found during the test, it is difficult to find out the specific location due to the intricate arrangement of the ventilation duct an...

Problems solved by technology

[0003] In the existing construction process, after the construction is completed, the airtightness test of the ventilation duct is required. Once the ventilation duct leaks are found during the test, it is difficult to find out the specific location due to the intricate arrangement of the ventilation duct and the long length of the ventilation duct. The air leakage position greatly prolongs the construction time
