Innovative refrigerator revolutionizes the way of cooling with the Peltier module, which contributes to efficient energy use with AI algorithm, longer food preservation and more internal space

Samsung Electronics Co., Ltd. today announced it will unveil the new refrigerators with AI Hybrid Cooling technology at CES® 2025, which will be ready to expand into global markets this year. These new refrigerators introduce AI Hybrid Cooling technology, which combines artificial intelligence with innovative cooling methods to meet the diverse needs of modern households.

“Since refrigerators run 24/7, we placed a strong emphasis on developing a cooling system that meaningfully enhances energy efficiency for users,” said Jeong Seung Moon, EVP and Head of the R&D Team for Digital Appliances Business at Samsung Electronics. “With the global unveiling of the AI Hybrid Cooling technology, we are showcasing our commitment to technological innovation in home appliances. We will continue to introduce home appliances that incorporate innovative technologies to make consumers’ daily lives more convenient.”

Optimize Energy Use Through Adaptive Hybrid Cooling

The AI Hybrid Cooling technology combines a highly efficient compressor with a Peltier module,[1] which is a semiconductor device that achieves cooling by harnessing the temperature change arising from the flow of electric current. The introduction of the Peltier module enables the refrigerator to function like a hybrid car, by using two power sources together only when needed to efficiently cool the inside of the fridge.

For instance, when significant cooling demand is detected or anticipated — like when many items are added at once after grocery shopping, or when storing hot food or if it’s the hot summer season — the refrigerator activates the Peltier module alongside the compressor. In normal use, however, it relies solely on the compressor to ensure optimal efficiency. During the process, the AI algorithm detects the current status of the refrigerator and predicts temperature changes inside the fridge to properly adjust the cooling mode.

The high-efficiency AI Inverter Compressor[2] also contributes to the efficient use of energy, thanks to an enhanced design that increases the radius of its rotating components. With 4.1 times greater inertia compared to Samsung’s conventional F3 compressor,[3] it operates longer while using less energy.[4] Leveraging an AI algorithm, the compressor dynamically optimizes its speed.[5].

As a result of continued efforts, Samsung plans to introduce a model that can be recognized as the Most Efficient[6] of ENERGY STAR in 2025 to the market.

Extend Freshness With Precise Temperature Control

The AI Hybrid Cooling technology enhances freshness for perishable foods with Hybrid Precise Cooling, which reduces internal temperature fluctuations in the fridge when activated — even during the device’s automatic defrost cycles. Since it leverages residual heat from its Peltier module during the defrosting process, it reduces the chance of excessive temperature fluctuations that can compromise food quality. As a result, the food ingredients can be kept fresher and longer. Tests show that when the Hybrid Precise Cooling is turned on,[7] fresh foods such as pork and salmon can last by up to 1.4 times and 1.2 times respectively,[8] compared to when it is turned off.

Secure More Storage and Everyday Convenience

The refrigerators featuring AI Hybrid Cooling technology redefine space efficiency with an impressive 900-liter capacity,[9] offering enhanced usability while maintaining the same external dimensions. By replacing traditional heating elements with a Peltier module, it better utilizes interior space, resulting in a 25-liter increase in internal capacity. This allows for 60mm deeper shelves[10] and a 13.8%[11] larger loadable area, accommodating up to 240 beverage cans[12] — 24 more than conventional models.

A Step Forward for Home Refrigeration

The refrigerators with AI Hybrid Cooling technology exemplifies Samsung’s dedication to combining intelligent technology, energy efficiency and user-centric design. Making its debut at CES 2025, this innovative appliance is poised to redefine modern home living and lead the way into a new era of AI-applied home solutions.

• When the temperature in the fridge rises above the normal range.
• When AI analyzes the user’s refrigerator usage patterns, predicts the temperature after a certain period, and detects situations like large-scale stocking or cleaning.
