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.
