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.

    Under normal operation, in a perfect system it will stay sealed. Problems come at end of life and in real world use. Seals aren’t perfect, gas escapes slowly. Some seals are bad, a blast chiller at my work needs regassing every other year. People dump old fridges and freezers on the street and they get damaged.

    It all gets out eventually.

      Yes, but the amount of gas in an AC system is insignifcant compared to the CO2 generated just making the AC system in the first place. Hell, delivering it probably generated significantly more pollution. Not saying we shouldn’t strive to make it better, but it’s not as actively harmful as it was 30+ years ago.

        Let alone running the damn thing (on fossil fuel electricity).
