Study on Reduction of Energy Consumption of Household Refrigerators-Freezers
In the last quarter of the century, a substantial amount of research work has been conducted on optimization of energy consumption by refrigeration systems and on proper design and construction of household refrigerator-freezers. The importance of such energy optimization schemes stems from the environmental impacts of Freon (R-12) used as the working refrigerant in household refrigerator – fre...

متن کاملPopping Noise in Household Refrigerators: Fundamentals and Practical Solutions
An intermittent noise that occurs around 30 seconds after compressor start-up has been disturbing customers of many domestic refrigerator manufacturers over the past 10 years. This noise is very similar to that produced by popcorn popping, being referred to as popping noise. The most probable cause of this strange and unpleasant noise is thought to be CIS (Condensation Induced Shock). The aim o...
متن کاملSimulation of the Transient Behavior of Household Refrigerators and Freezers
Due to their contribution to the ozone depletion and the anthropogenic greenhouse warming effect caused by the refrigerant as well as the foam blowing agent household refrigerators and freezers were attracting public attention especially in Western Europe. The conversion to the use of environmentally benign fluids as refrigerants and foam blowing agents requires a large number of extensive, exp...
متن کاملNumerical Simulation of a Reciprocating Compressor For Household Refrigerators
This paper presents a method for the numerical simulation of reciprocating compressors for household refrigeration. The compressor is regarded as a set of volumes and one-dimensional, variable-area ducts connected together. The model describes all relevant features of the compressor, including suction and discharge mufflers and automatic valves. The equations governing the unsteady flow of a re...
