The gas engine and the steam engine are used for converting heat energy into mechanical energy to generate motive power. The refrigerant consumes a certain amount of mechanical energy in the compression refrigeration device to transfer heat from a low temperature to a high temperature so as to achieve the purpose of refrigeration.

Therefore, we propose a working medium circulation working system.
