Experimental study on sound transmission in condenser
نویسندگان
چکیده
Even though there are lots of work studying acoustic resonance in tube bundles, the sound transmission rules barely got researchers attention. And most papers published assume that there is no interaction between the acoustic and structure modes. This paper tries to realize how sound source affects the acoustic transmission and whether the acoustic resonance could couple with the structure. A series of tests on model condensers were conducted. Results show that sound source at steam inlet contributes the most to the sound level of water outlet. And the acoustic resonance could couple with the structure. Besides, the transmission of sound is dominated by the structure.

متن کاملDevelopment and Validation of Sound Transmission Loss Measurement System for Measuring Muffler Performance
Muffler is a part of the vehicle exhaust system that absorb or reflect sound waves to reduce exhaust noise. One of the most important determinants of a muffler performance is the amount of attenuation that has on its input wave; this parameter is known as sound transmission loss. Four - mic standard test is one way to determine this parameter which is used in this paper. In this study, a test d...
متن کاملInvestigation on acoustic behavior of acoustic porous absorbers to absorb sound energy and transmission loss index
In this study, the acoustic properties of porous absorbents with different porosity levels have been evaluated using different mathematical models. These models use one or more parameters of materials for calculating acoustic characteristics. In all of these models, materials are considered as equivalent fluid and reactionary characteristics have not been taken into account.

In this paper,
 the application of evaporative cooling for refrigeration cycle to reduce power consumption in hot climates is emphasized. Experimental and analytical investigations were performed in order to specify the effect of evaporative cooling condenser instead of the commonly used air cooling condenser in window-air-conditioners. Evaporative condenser can reject more heat, thereby pre...
