Example Embodiment
[0025] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings:
[0026] Such as figure 1 As shown, the carbon dioxide cylinder 1 stores liquid carbon dioxide, which is the source of carbon dioxide for the entire experimental system. The carbon dioxide flows into the constant temperature water bath cold box 3 under its own pressure (above 4.5 MPa) in the gas cylinder 1; the cooler 2 pairs the constant temperature water bath The circulating water in the cold box 2 is cooled down (0~3℃), and then the carbon dioxide in the box is cooled; the liquid carbon dioxide enters the booster pump 5 through the flow meter 4, and the pressurized liquid high-pressure carbon dioxide is pumped into the constant temperature water bath hot box 7 , The heating device 6 is heated by the circulating water in the hot box 7, and the temperature of the hot box 7 can be adjusted between 20 and 100°C with an accuracy of ±0.5°C.
