Background

Working media are short for working substances, and various heat engines or thermal equipment use the working media to convert heat energy and mechanical energy into each other.

The medium material for realizing the mutual conversion of the heat energy and the mechanical energy is called a working medium, the working medium can obtain work only by the state change, such as expansion, of the medium material in the heat engine, and the energy conversion can be realized only by the working medium. When gas is used in gas engine and steam is used in steam engine, heat energy is converted into mechanical energy to produce motive power. The refrigerant consumes a certain amount of mechanical energy in the compression type refrigerating device to transfer heat from a low temperature to a high temperature so as to achieve the aim of refrigeration. The use of compressors, blowers or ventilators to compress air to varying degrees to increase its pressure is also essentially a process of converting the mechanical energy provided by the prime mover into heat energy.
