In Europe there are energy consumption regulations for household equipment like fridges, see: https://commission.europa.eu/energy-climate-change-environment/standards-tools-and-labels/products-labelling-rules-and-requirements/energy-label-and-ecodesign/energy-efficient-products/fridges-and-freezers_en https://commission.europa.eu/energy-climate-change-environme... . What energy label would your fridge from 70 years ago have?
- ilyt 3y agoIt actually might be pretty decent one as it was using freon which is very good at its job. The process didn't change all that much, neither did engines used in compressor so it is mostly "how well isolated the fridge is"
- pfdietz 3y agoCurrent refrigerants are also very good, they're just more expensive. I doubt the refrigerator from 70 years ago had blown foam insulation (polyurethane insulation was introduced in refrigerators in the mid 80s), so it probably had terrible efficiency. It may have clawed some of that back by lacking automatic defrosting. https://dura-foam.com/assets/images/2-0/energy-consumption.png https://dura-foam.com/assets/images/2-0/energy-consumption.p...
