Air conditioning unit muffler measures have what

 The noise of air-conditioning unit is affected by the refrigerating compressor, air duct and cooling fan in the unit. Among them, the aerodynamic noise generated by the cooling fan is mainly concentrated in the exhaust port on the top of the air-conditioning unit, and propagates outward with the air as the medium, and the fan noise is also closely related to the fan speed, blade angle, shape and so on. The air duct and refrigeration compressor are mainly mechanical vibration noise generated by the operation of the equipment, this kind of vibration sound wave mainly by solid structure transmission. So air conditioning unit muffler measures have what? 1. Muffler, Muffler Control air conditioning unit through the ventilation duct, transmitted to the sound point and air flow noise in the duct. The utility model is also applied to the air inlet and outlet of the equipment room such as the air-conditioning machine room, the boiler room, the refrigeration machine room, etc. . 2. Damping, eliminate the vibration source equipment and sound transmission medium between the rigid connection. In order to control the noise of the air-conditioning system, it is necessary to control the solid sound transmitted by the vibration of the air-conditioning unit and the refrigeration equipment, and to avoid the forced vibration of the ventilation duct. Common methods are to install shock absorbers, increase the vibration isolation hose, pipe damping bandage and so on. 3. Sound Insulation, refrigeration host, frozen water pump, cooling water pump and other large noise refrigeration host, cooling water pump is basically set in the basement. In order to reduce the influence of the equipment noise on the floor room, the sound insulation treatment can be carried out on the machine room wall and floor. In addition, the roof of open-air equipment can be surrounded by noise barriers to reduce the impact of noise.
