Abstract: This application discloses example frequency control methods, frequency controllers, processors, and electronic devices. One example method includes obtaining at least two temperatures of a processor core, where each of the at least two temperatures corresponds to a frequency. A load change mode of the processor core is determined, where the load change mode indicates a change status of a load of the processor core. A target temperature is determined from the at least two temperatures of the processor core based on the load change mode. A frequency of the processor core is adjusted based on the target temperature.

Abstract: A building heating or cooling system is disclosed that includes an air handling system having an air delivery flow path in fluid communication with a conditioned space in the building. The building heating or cooling system also includes an electrocaloric heating or cooling system that includes first and second electrocaloric modules. A first inlet receives air from the conditioned space or the air delivery flow path and directs it through the first or second electrocaloric module to a first outlet to the conditioned space or the air delivery flow path, and a second inlet that receives air from the conditioned space or the air delivery flow path and directs it through the first or second electrocaloric module to a second outlet to outside the conditioned space.

Abstract: A building heating or cooling system is disclosed that includes an air handling system comprising an air delivery flow path (44) in fluid communication with a conditioned space (40) in the building. The building heating or cooling system also includes an electrocaloric heating or cooling system (10, 11) that includes first and second modules (12, 14). A first inlet receives air from the conditioned space (40) or the air delivery flow path (44) and directs it through the first or second module (12, 14) to a first outlet to the conditioned space (40) or the air delivery flow path (44), and a second inlet that receives air from conditioned space (40) or the air delivery flow path (44) and directs it through the first or second module (12,14) to a second outlet to outside the conditioned space (40).
