A muffler for heating, ventilation and air flow in construction engineering

Abstract

The invention provides a muffler for heating and ventilation air flow in construction engineering, which includes a box structure; a reinforcement structure is installed at the left end of the box structure; an inlet structure is installed at the left end of the reinforcement structure; an inner pipe structure is installed inside the box structure; A noise reduction structure is installed between the inner pipe structure and the box structure; an outlet structure is fixed at the right end of the box structure; the inlet structure also includes a mounting head and a balance ring, and the mounting head is installed at the outer end of the reinforcement structure. The mounting heads are set in four groups in a circular array, and each group of mounting heads is hinged with a balance ring. The balance ring is set as two layers of inner and outer layers. The space is also hinged, so that the balance ring can always maintain a balanced state, so that the installed entrance structure can withstand multi-directional external forces, thus ensuring the stability of the entrance structure.

Description

technical field [0001] The invention belongs to the technical field of construction engineering equipment, and more specifically relates to a construction engineering HVAC muffler. Background technique [0002] Building HVAC, the main functions of HVAC include: heating, ventilation and air conditioning. The comprehensive abbreviation of these three functions is HVAC. HVAC is a household central air conditioner. The biggest feature of central air conditioner is that it can create a comfortable indoor environment. The general split air conditioner in the home can only solve the heating and cooling problem, but cannot solve the air treatment process. The heating of large buildings mostly sends hot air to each room through the HVAC pipe. friction, resulting in noise, so a muffler will be installed when entering the room. [0003] Application number: In the patent of CN201820499497.X, the invention discloses a construction engineering HVAC muffler, which includes a HVAC pipe jo...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a muffler for heating and ventilation air flow in construction engineering to solve the friction between the warm air inside the existing pipeline and the pipeline, resulting in noise. Therefore, a muffler will be installed when entering the room, but the existing The overall structure of the current muffler is relatively simple, and it can only be used for single-layer or single-group muffler, which cannot achieve the corresponding muffler effect, and the overall pipeline will shake when the airflow is too large. The general muffler does not have the ability to dampen the pipeline problem of effect
