Researchers in South Korea have developed a new type of heat pump that can turn low-temperature waste heat from factories and data centers into cooling. Together, they created a next-generation chemical adsorption heat pump that operates using waste heat at temperatures of only about 40°C (104°F), much lower than what existing systems require. Instead of relying mainly on electricity, it uses waste heat that is already being produced by industrial facilities and data centers. The new technology overcomes this limitation by successfully producing cooling using waste heat at only 40°C. One of the biggest improvements comes from redesigning the adsorption bed, which is the heart of the heat pump.
