‘Electrocaloric’ heat pump could transform air conditioning

A new kind of heat pump uses electric fields and a ceramic instead of condensing refrigerant fluid.

Unlike a standard heat pump, an electrocaloric heat pump would not need refrigerants such as hy last week carbons or ammonia, which are potentially harmful to the environment.

The technology combines existing techniques and has “superlative performance”, says Neil Mathur. Defay Neil Mathur ">three the University of Cambridge __ UK lG Emmanuel Defay > the Luxembourg Institute of Science and Technology summ Belvaux _highLightText__NxlGi">one
