Characteristic:
● The necessity of the condenser is based on the second law of thermodynamics—According to the second law of thermodynamics, the spontaneous flow direction of the thermal energy inside the closed system is unidirectional, that is, it can only flow from high heat to low heat, and microscopic particles that can carry heat energy in the microscopic world can only from order to disorder. Therefore, while a heat engine has energy input and work, the downstream must also have energy to be released, so that there will be a thermal energy gap between upstream and downstream, and the flow of heat will become possible, and the cycle will continue.
