The elevator noise insulation cotton
board installation should pay attention to the problem: air-cooled heat
pump
air conditioning project noise control is the first stage in the
equipment selection phase should choose a lower
noise brand, the current single air-cooled heat pump noise is generally
65 ~ 85db , Each additional unit, the
overall noise will increase 3db, when a project in the number of heat
pumps when the number of more difficult to
control the noise. Therefore, in the selection of heat pump unit number
should not be too many projects, in other
words is the heat pump should not be used in large-scale
air-conditioning project, the general situation of a
project should not exceed the number of units 5 sets. In addition, in
the layout of the unit should be considered
in addition to smooth ventilation, to avoid the return air outside the
base of the unit and the inlet and outlet
pipes must be installed shock absorber, the isolation efficiency to meet
the design requirements. In the cooling,
heating stations in the main air-conditioning water pipes to be
installed with damping hanger or bracket to
prevent the vibration of the unit and pump through the pipeline to other
places. Furthermore, in the case of
conditional units should be arranged as much as possible in the main
building roof, reducing the noise on the
main building itself and the surrounding environment. 2, you can stand
on top of the elevator with the elevator
up and down the operation of the elevator sound insulation board
installation and construction, so more
convenient and safe; ¡¾must be wearing seat belts¡¿ 3, the installation of
the car, No large quantities of
maintenance, it will not lead to damage after the installation of
cross-operation; 4, the effect of installed
after the appearance of beautiful, clean and tidy..
