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.

    Coefficient of performance (i.e. energy efficiency) at decent delta-T is always the most important factor and rarely mentioned.

    Modern cooling equipment generally has the largest environmental impact from energy consumption, not manufacturing or refrigerant leakage.

    Especially with ultra-low-GWP propane or butane refrigerant, though that’s not usually used in large-scale systems.
