Measurement and control method of medium parameter

Abstract

The invention discloses the measurement and control method of a medium parameter. The method comprises the following steps of pumping the internal environment of a container into a vacuum environmentand injecting a medium to be measured into the container; observing and controlling a liquid gas amount, using a sensor to collect a temperature and the intensity of pressure in the container, and sending to a measuring and controlling instrument, and uploading to a detection control module; feeding back the environment in the container according to the collected data by the measuring and controlling instrument; and recovering the environment in the container to standard atmospheric pressure and taking the medium to be measured. By using the measurement and control method of the medium parameter, problems that the parameters of upper steam and a bottom liquid in the container can not be acquired in real time and at the same time; and feedback control can not be performed on the medium to be measured in the prior art can be effectively solved.

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...
