Statistical Analysis of Capillary Tube Variations in Refrigerators

چکیده
This paper presents the results of a statistically designed experiment with eight all-refrigerator cabinets. The cabinets were designed with a view to be identical except for the fact that each cabinet was fitted with a specific non-adiabatic capillary arrangement. These cabinets were tested to the New Zealand test standard (NZS 6205.2) at 32°C ambient temperature and then the tests were repeated at 10°C to study the effect of low ambients on the refrigerator performance. The effect of capillary tube variations has been investigated with respect to power consumption, the stability of the compressor cycle and the refrigerant subcooling in refrigerators.

متن کاملNoise Generation in Household Refrigerators: An Experimental Study on fluid Borne Noise
The oscillatory pressure disturbance created by the refrigerant flow through pipes and components is one of the main sources of noise in household refrigerators. This type of excitation is transferred to the pipes and the vibratory energy travels through the structure reaching the cabinet from which it radiates as sound energy. In order to obtain a better understanding of this type of noise a h...
