This paper mainly focuses on consumer research in designing or shaping a comprehensive label. The stack material desired thermal properties like the thermal conductivity and specific heat have been discussed. Thus stack is the heart of any thermoacoustic refrigeration system. Moreover, the coefficient of performance of the thermoacoustic refrigerator is observed to increase at the resonance frequency of each stack configuration. Based on the obtained results, the resonance frequency change was observed by changing the stack different geometric parameters. Two frost free household refrigerator freezers of the same capacity were tested in the laboratory to determine the sensitivity of their energy consumption to various usage conditions.
This study comprises of two parts, in first part different components of thermoacoustic refrigerator are fabricated based on numerical design. The paper is particularly concerned with developing a proposed energy guide label for household refrigerator-freezers through consumer research. With the experimental data, a multiple regression equation is developed to investigate their combined effect. A dimensionless stack position from 0. Ads help cover our server costs. The results with atmospheric air demonstrates the influence of the stack geometry on the cooling power and shows that some its geometrical parameters are interdependent. Behavior of changing the operating conditions effect on the performance is discussed.
The system can be taken apart if different stack geometry or material is to be studied.
Help Center Find new research papers in: Celcor Ceramic stacks of normalized positions of 0. Finally, energy consumption according to the regression equation with optimum setting conditions is compared with ISO standard test conditions.
The experiments were conducted to investigate the effect of single variables, such as temperature, thermostat setting positions and door opening, and their combined effect on energy consumption. Behavior of changing the operating conditions effect on the performance is discussed.
An experiment was conducted to investigate the effect of room temperature, door opening, thermostat setting position, relative humidity, and loading on energy consumption of a household refrigerator-freezer.
So, this is a vast area of work. This paper mainly focuses on consumer research in designing or shaping a comprehensive label. A dimensionless stack position from 0. The resonance frequency is important for the performance of thermoacoustic refrigerators, as it affects the temperature difference Thermoacoustic refrigeration is a form of the emerging green technologies based upon the use of the pressure acoustic waves to researcj the cooling effect.
The present study investigates experimentally and theoretically the behaviour of the An error analysis is done for the measured properties and the maximum relative error was of 2. The experimental resonance frequency change was with the same trendline as DeltaEC results. Remember refrigerarion on this computer. With the experimental data, a multiple regression equation is developed to investigate their combined effect. Use of CFC-contained systems reftigeration caused severe environmental hazards that have researchers looking for alternatives.
The stack material desired thermal properties like the thermal conductivity and specific heat have been discussed. Skip to main content.
Role of ambient temperature, door opening, thermostat setting position and their combined effect on refrigerator-freezer energy consumption. Thermoacoustic refrigeration is an evolving cooling technology in which the acoustic power is used to pump heat. This paper provides a brief overview of the construction and functioning of thermoacoustic refrigeration system and focuses on stack of a thermoacoustic refrigeration system.
Later performance of the device is then analyzed.
