At laboratory stage but promising:

Heat pumps without compressors: Fraunhofer advances electrocalorics

"Novel concept: solid-state #HeatPumps based on #electrocaloric materials that do not run on harmful #refrigerants and could potentially be more efficient than compressor-based systems."

Cooling system could replace air con and drastically cut energy use

A heat-pump-like system that relies on a phenomenon called electrocaloric cooling could heat or chill a room almost twice as efficiently as standard air-conditioning units
