1, adjust the freezers at the bottom of the four foot flat �.Freezer should be on the floor smooth hard place.Will be at the bottom of the four legs on a flat surface, make it flat �.Many of air-conditioner has 4 feet at the bottom of the knob, can be fixed by noise is one of the biggest time to adjust.If there is no adjustable knobs device, can be placed at the foot of air-conditioner such as cushion to �, and reducing noise to a minimum

.
2 was strengthened, pipeline and cabinet firmly.Inspection for the pipe adjustment and cabinet whether the connection between the reinforcing part is loose, when he worked in the compressor, in order to avoid resonance.So you must add spring washer, outside line and firm, to ensure that the bolt is not loose.
3, compressor base must be firmly fixed.Pressing with purchase often-expensive compressors, noise greatly reduced, raised his hand and the noise and increase.In general, for compressor is the base of vibration damping pad uneven or bolt looseness, compressor base is not strong, need adjustment, tighten the bolt connection part, and loss of elasticity of replacement of gaskets. 4, fittings must be installed firmly.Freezer, freezer must be securely mounted in a fixed position and sink, so that users can directly use the refrigerator, hierarchical network, drawer and other accessories.Don't placed on top of air-conditioner sundry, preventing resonance caused by noise.If there is a fault
5, determine the compressor.With the hand press the compressor will not reduce noise at the top.Generally speaking, if the compressor internal piston and the cylinder clearance is too large, produce noise, you must replace the compressor.Freezers don't open the door, from 3 meters, clearly at the sound of hot pot and interval & other;Pick”Voice is cooling line fault, need to ask an expert to repair.
6, the rubber piece of inhibition of the pipe vibration.Freezers when using noise is very big, so the bike external contour cut into a diameter of 30 mm round, from the middle cut out 5 mm diameter circular hole, and then cut from the outside to the center, let the eraser affixed to the tube.Compressor starts up, touch the pipe will produce feelings of jitter pipe can clip on a few of these rubber block, a freezers need 10-20, will soon be reduced noise.Because the rubber piece can inhibit the pipe vibration caused by & other;Resonance & throughout;. 7, freezers four feet on shakedown is appropriate.Will be on 3-6 cm high liner, adjust the square flat �, increase the air convection space at the bottom of the box.In this way, the noise of the compressor and the other noise can be out from the bottom of the cabinet, reduce the noise produced by the air-conditioner on both sides and upper.
8, metope and back into a certain Angle.To the back of the freezer and metope tilt Angle, and metope l - 3 degrees, back side of the side of the air-conditioner big mouth, a side has a small mouth, forming the horn shape.Big edge noise is very big, must face the object.Little respect to the noise is small, in the face of people activity areas.
9, sound-absorbing board of insertion along the wall.Glass fiber cotton and other sound-absorbing material paste on the board, and then paste cardboard into the wall behind the air-conditioner compressor side), cardboard than behind the air-conditioner 10 cm to 20 cm.
