Abstract

The utility model relates to a sound-proof noise-eliminating cover for a refrigeration and compression condenser. The noise-eliminating cover is a box body. The plate walls of the front side, the back side, the top side, the right side and the left side of the box body are steel plate inner walls, and a layer of damping slurry is coated on the steel plate inner walls. A layer of glass cotton is tightly attached to the damp slurry, glass fabrics are covered outside the glass cotton, and the inner portion of the box body is divided into an air intake sound-eliminating chamber, an extruder sound-proof chamber and an exhaust sound-proof chamber. An air intake is arranged on the outer plate of the air intake sound-eliminating chamber, and an exhaust port is arranged on the outer plate of the exhaust sound-proof chamber. When the utility model is used, a compressor unit is covered by the noise-eliminating cover, and noise can be effectively reduced, which is favorable for people's production and life.

Description

The sound insulation sound proof housing of refrigerant compression condensation unit

The utility model is the noise reduction sound equipment that is used for the outer unit of compression of split type refrigeration system.

At present, both at home and abroad the medium-sized outdoor unit of refrigeration system places in the special-purpose machine room mostly to reduce noise interference to external world, promptly refrigeration compressor is placed machine room, to prevent people's work life around the compressor noise influence.Carry on a shoulder pole this method and will expend very big computer room construction expense, moreover be subjected to restrictions such as urban construction, the appearance of the city, planning, some occasion also should not be repaiied machine room, for small-sized outdoor unit, generally be that machine room is not repaiied in open-air placement, but sometimes in the resident compact district or unit when the resident is too near, also need to reduce its noise.

The purpose of this utility model is in order to solve the problem of above-mentioned existence, a kind of sound insulation sound proof housing of refrigerant compression condensation unit to be provided.It can realize reducing the compressor bank noise, guarantees the compressor ventilation and heat simultaneously.

In order to achieve the above object, the sound proof housing that is characterised in that of the present utility model is a casing, the front of casing, back, end face and about the wooden partition of face be to scribble one deck damping slurry on the steel plate inwall, being close to damping slurry establishes one deck glass wool, glass wool and coats glass fibre cloth outward, be separated into air intake anechoic chamber press sound proof chamber and air draft anechoic chamber in the casing, air intake anechoic chamber outside plate is provided with intake grill; Air draft anechoic chamber outside plate is provided with exhaust port.

The casing internal partition is to be made of steel plate, damping plate, glass wool and glass fibre cloth, is distributed with through hole on its light plate.

The steel plate pore diameter range 3-10mm of dividing plate, the occupying of hole area at 2%-8%.

Air intake is provided with centrifugal blower in the anechoic chamber.

Glass wool thickness is at 30-50mm.

Described steel plate thickness is at 0.6-2.0mm.

The utlity model has following advantage and good effect: the noise spectrum scope of refrigeration compressor is wide band, make a chest with sheet metal, then the unit cover is got up, because the steel plate inwall scribbles one deck damping slurry, be close to damping slurry, laid one deck super glass wool again, super glass wool is as sound-absorbing material, the high frequency reverberation sound is had the sound-absorbing attenuation, and the noise ripple of having decayed is blocked by steel plate basically through after the damping loss effect of damping slurry.Baffle plate in the installing of sound insulation sound proof housing inlets and putlets of ventilation place is the perforated plate of 2-8%, can absorb the medium and low frequency voice with the cavity resonance form, be equipped with on the intake grill-the centrifugal blower fan of Tai low noise, can guarantee that press ventilates, heat transfer boundary condition is good, can guarantee that normally operation under the throat condition is falling in press.

Fig. 1 is a main sectional view of the present utility model;

Fig. 2 is a vertical view cutaway drawing of the present utility model;

Fig. 3 is a left view of the present utility model.

(1) wooden partition; (2) air intake anechoic chamber; (3) press sound proof chamber; (4) air draft anechoic chamber; (5) intake grill; (6) exhaust port; (7) dividing plate; (8) blower fan.

Referring to Fig. 1, Fig. 2, Fig. 3, sound proof housing system or rectangular bin, the wooden partition of bin (1) outermost surface is the 1mm steel plate.Be coated with one deck damping slurry on the steel plate inwall, the about 3mm of thickness is close to damping slurry and lays one deck super glass wool again, and thickness is 35mm.Coat with glass fibre cloth then.Be provided with a low voice centrifugal blower (8) in the air intake anechoic chamber (2), it can guarantee that press ventilation heat exchange condition is good.The steel plate of dividing plate (7) is a perforated plate, and the aperture is ψ 5mm, and the area in hole (also claiming punching rate) accounts for about 4.5%.During use, compressor bank with sound proof housing cover dress, can be reduced noise effectively, be beneficial to people's production, life.
