EFFECT OF COOLING HERMETİC COMPRESSOR ON NOISE REDUCTION IN A DOMESTIC REFRIGERATOR

Summary: In the household refrigerator compressor is the main source of noise and heat, and the isolation of sound from the compressor in the air increases the thermal stress of his work and a significant reduction of energy efficiency of the refrigerator. Installing sound insulation panel in front of the compressor housing to reduce the noise level. The cooling system compressor oil is widely used in foreign and domestic refrigerators, implements "tropical" operating temperature Options refrigeration units tested at optimal doses of freon and constant permeability of the capillary tube. Soundproofing compressor housing leads to some increase in temperature of the motor windings and optimization of dose refrigerant with soundproofed compressor housing will increase the value of these indicators. The results confirm the possibility of reducing the noise of the refrigerator, through the use of an optimized heat removal from the cylinder head of the compressor.
