Samsung just announced new hybrid cooling tech coming to its refrigerators in 2025. They’ll use a traditional compressor alongside a new Peltier module — a semiconductor device that transfers heat from one side to the other when current passes through it. This approach results in a fridge that reduces temperature variations to keep foods fresher longer while better utilizing interior space, according to Samsung.
The Peltier effect is something we’ve seen harnessed by wearable personal air conditioners, microclimate chairs, and hobbyist coolers in the past. This is the first time we can recall seeing it used in a full-sized refrigerator sold by a major brand.
Samsung says the Peltier module is only called into action when significant cooling is needed. This might be after loading the weekly shopping haul into the fridge or when adding hot leftovers. In these situations the Peltier module works alongside the compressor to avoid a big internal temperature spike. Otherwise, the fridge relies exclusively on the compressor for optimal cooling efficiency. Samsung says its hybrid cooling tech will be introduced into a fridge (model RM80F23VM) that can be “recognized as the most efficient of Energy Star in 2025.”
Samsung’s fridges featuring the new hybrid cooling tech will be available with 900-liter capacities. The company says they have a 25-liter increase in usable internal space as a result of using a Peltier module instead of traditional heating elements. And according to Samsung, its hybrid cooling can keep foods fresher for longer, with tests showing pork lasting 1.4 times longer and salmon 1.2 times.
Expect to hear more from Samsung about its hybrid cooling fridges in early January when the big CES trade show kicks off in earnest from Las Vegas.
