As we increase the temperature, the solid changes to a liquid. And then changes to gas. And that’s what we would expect. We certainly know that happens with ice. It goes from a solid to a liquid and to a gas, if we keep the pressure constant.Now, let’s do it the other way ...

High-pressure liquid(液态) CO₂ goes through them to create heat(热) exchange. The CO₂ evaporates(蒸发) under the ice surface. The evaporation takes in heat and turns water on the surface into ice. And the CO₂ goes into another circle. This technology helps to make ice better and...
