A heat transfer system cycles between a first mode where a heat transfer fluid is directed to a first electrocaloric module and from the first electrocaloric module to a heat exchanger to a second electrocaloric module while one of the first and second electrocaloric modules is energized, and a second mode where the heat transfer fluid is directed to the second electrocaloric module and from the second electrocaloric module to the heat exchanger to the first electrocaloric module, while the other of the first and second electrocaloric modules is energized. The modes are repeatedly cycled in alternating order directing the heat transfer fluid to cause a temperature gradient in each of the first and second electrocaloric modules, and fluid from a flow path between the electrocaloric modules is mixed with circulating fluid from a conditioned space to cool or heat the conditioned space.

An elevator car () comprises: a cab () having a top, a bottom, a left side, a right side, a front, and a back, the front having a door (); and a frame () supporting the cab. The cab comprises a perimeter shroud () protruding above a surface of the top and leaving a well () exposing a central portion of an upper surface () of the top; the perimeter shroud protrudes above the upper surface; and the perimeter shroud has, in vertical section, a curved portion.
