In refrigerators, defrosting (or thawing ) is the removal of frost and ice. A defrosting procedure is generally performed periodically on refrigerators and freezers to maintain their operating efficiency. Over time, as the door is opened and closed, letting in new air, water vapour from th...

Prediction of change in composition ratio when mixed refrigerant leaks In a heat pump system, refrigerant mixtures are considered as promising alternative refrigerants. However, unlike pure refrigerants, the main drawback of mixtures is a change in composition during refrigerant leakage. Consequently, the combined effects of reduced charge and composition variation during leakage result in a degradation of performance. We select the various leakage scenarios that could occur in the heat pump sys...

Engineers have devised a novel strategy to inhibit its formation. They demonstrated that a textured surface modified with a graphene oxide layer can inhibit entire frost formation for up to a week, or longer. This makes the new surface 1,000 times more effective than previous solutions in the market. This innovative design mimics the natural patterns found in leaves. Moreover, the scalable surface design exhibits resistance to cracks, scratches, and contamination · “Unwanted frost accumulation is a major concern across industrial, residentia ...
