Last time I introduced the display fridge. Today we’ll learn a bit about the closed you see at supermarkets which have glass doors and are all lined up in the frozen food section.
In reference to the sealed display refrigerators, e.g. the reach-in frozen goods refrigerators as mentioned before, one can observe that they are typically ordered in large rows. Each consumer may pace next to a whole aisle of these display refrigerators, showing piles of frozen yogurt, frozen pizzas and other frozen products. These banks of commercial refrigerators are not individually chilled. Rather, a single compressor component give compressed refrigerant gas to each individual appliance. After the depressurization period, the freon is returned out into a common condensor. Such multiplexing of the cooling cycle is a wonderful boost to energy savings. On top of that, there is stable chilling across all of refrigerators. But the unresolved problem is should the single compressor fails. Should this happen, the entire set of refrigerators would halt at once. The disadvantage is obviously such a centralized arrangement is extremely sensitive to energy disruptions. In order to resolve such issue by putting in individualized engines would abolish any monetary advantages of the former layout. The prevailing argument for the centralized layout falls on the consistent refrigeration.
