Researchers have built the first refrigerant-free system to reach sub-zero temperatures, a breakthrough that could reduce food waste and greenhouse gas emissions.

Imaging if this technology could cool a data centre.

Edit: I was not involved in this project. You are wasting your time asking me questions.

    Some sources claim much higher efficiency. This makes sense to me since you are not limited by your coolant’s properties so much and don’t have to maintain pressure. But I can’t do in depth research for you.

      What sources?

      The article doesn’t list any. All it says is they reached a cooling temperature of -12°C, but has no information on the energy used to achieve that.

        Google “elastocaloric heat pump efficiency” thats the technical term.

          I’m asking what saurce you have that says that they are more efficient than refrigeration systems because everything I find says the opposite.
