Experimental study of the effects of the cycle characteristics on the refrigerant-induced noise in system air-conditioner

Abstract: The main sources of the refrigerant-induced noise can be classified 2 types according to its characteristics. One is due to the cyclic characteristics such as quality, velocity of the refrigerant, pressure drop and mass flow rate. The other is due to the structural characteristics such as distributed path pipe layout, distributor and expansion device. In this paper, the effects of cycle characteristics on the noise of multi-type system air-conditioner are investigated experimentally. In the indoor unit of mult… Show more

“…Noise is a pervasive aspect of living and work environments, thanks to urbanization and industrialization, for examples, factory, traffic, car, airconditioner noise, etc. [2][3][4][5]. Particularly, low frequency noise, the frequency of which ranges below 100 Hz, is generated by many machines commonly used in the working environment, such as fans, blowers, compressors, and so on [6].…”

“…Bubbles behave as a non-linear oscillator, and their mathematical dynamic modeling can be quite complicated. Figure 2 illustrates geometrical boundary conditions adopted in the literature (MINNAERT, 1933;DEVIN, 1961;BLUE, 1967;JEONG;KIM, 2011) in the development of theoretical models for the natural frequency of bubbles. Source: Adapted by author from Minnaert (1933), Devin (1961), Blue (1967) and Han, Jeong and Kim (2011).…”
