1. An electrocaloric heat transfer system, comprising:
a first electrocaloric module comprising a first electrocaloric element disposed between electrodes, a first port, a second port, and a first fluid flow path between the first port and the second port in thermal communication with the first electrocaloric element;
a second electrocaloric module comprising a second electrocaloric element disposed between electrodes, a third port, a fourth port, and a second fluid flow path between the third port and the fourth port in thermal communication with the second electrocaloric element;
a fluid inlet configured to receive fluid from a heat source or heat sink, and to controllably direct the fluid to the first port or the fourth port;
a fluid outlet configured to controllably receive fluid from the first port or the fourth port, and to discharge the fluid to the heat source or heat sink;
a third fluid flow path between the second port and the third port, the third fluid flow path comprising a fluid mixer comprising mixer fluid inlets in controllable communication with the second port, the third port, and a conditioned fluid space, and a fluid separator comprising a separator fluid inlet that receives mixed fluid from the fluid mixer, a separator first fluid outlet in communication with the second or third port, and a separator second fluid outlet in communication with the conditioned fluid space.
