Modern ULT freezers employ HC (i.e., hydrocarbon) gas mixtures: typically, ethane and propane. [16] [17] This technology was developed in the mid-1990s, [18] and improved efficiency by up to 30% over the conventional CFC or HFC gassed freezers. [19] [20] Alternatively ULT freezers may use the Stirling cycle in reverse (A Stirling cooler) for ...
For refrigerating appliances, such as refrigerators, freezers, wine-storage appliances, and combined appliances, the labelling is specified in terms of an energy efficiency index EEI, which is an indication of the annual power consumption relative to a reference consumption that is based on the storage volume and the type of appliance (refrigerator or freezer).
The hexagonal packing of circles on a 2-dimensional Euclidean plane. These problems are mathematically distinct from the ideas in the circle packing theorem.The related circle packing problem deals with packing circles, possibly of different sizes, on a surface, for instance the plane or a sphere.
Domestic freezers can be included as a separate compartment in a refrigerator, or can be a separate appliance. Domestic freezers may be either upright, resembling a refrigerator, or chest freezers, wider than tall with the lid or door on top, sacrificing convenience for efficiency and partial immunity to power outages.

The most appealing part of this research is how potentially energy efficient and environmentally friendly this cooling technology is. The different materials used, commonly shape-memory alloys, provide a non-toxic source of emission free refrigeration. The most commonly studied materials studied are shape-memory alloys, like nitinol and
Since April 2013, the CT series compressors designed in-house were launched into production; these compressors are suitable for producing refrigerators with energy efficiency class of A+++. In 2014, Atlant freezers won the award for Best of the Year in the freezers category at the international Best of the Year competition held in Ukraine. [6]
