These findings underscore the potential of breathing- caloric materials like MOF-508b for innovative applications in HVAC&R. With their substantial thermal shifts and relatively low operating pressures, these materials offer a viable path toward energy-efficient,
eco-friendly heat-pumps and refrigeration technologies, potentially achieving even sub-zero temperatures. This research represents a step forward in sustainable thermal management solutions, aligning with global energy transition goals.
