Abstract

The invention discloses a method for measuring and controlling medium parameters, which includes: pumping the internal environment of the container into a vacuum environment, injecting the medium to be measured into the container; observing and controlling the amount of liquid and gas, using a sensor to collect the temperature and pressure inside the container, and sending it to the measurement and control system. The instrument is uploaded to the detection and control module; the measurement and control instrument gives feedback to the environment inside the container according to the collected data; the internal environment of the container is restored to the standard atmospheric pressure, and the medium to be tested is taken out. The method for measuring and controlling the medium parameters disclosed by the invention can effectively solve the problem that the prior art cannot obtain the parameters of the upper steam and the bottom liquid in the container in real time and at the same time, and cannot perform feedback control on the medium to be measured.

Description

technical field [0001] The invention relates to the technical field of measurement and control, in particular to a method for measurement and control of medium parameters. Background technique [0002] Due to the characteristics of high heat transfer coefficient, high insulation, non-toxic, non-flammable, and environmentally friendly, phase change cooling technology has gradually become the main heat dissipation method for high-power power electronic equipment and devices in applications such as electric vehicles and flexible direct current transmission. [0003] In the existing research on a large number of phase change cooling technologies, the key technologies of measuring and controlling the medium environment, boiling state, temperature and pressure are all involved. Measurement and control technology has a strong coupling relationship with electrical tests such as electrical properties of materials, device insulation properties, and aging tests such as material compati...
