Thermoâs documentation is available on the web:Ĭreate a pure-component flash object for the compound âdecaneâ, using the Peng-Robinson equation of state. $ git clone git:///CalebBell/thermo.git Documentation Install Thermo in your environment from conda-forge channel with: If you have an installation of Python with pip, simple install it with:Īlternatively, if you are using conda as your package management, you can simply If you need to know something about a chemical or mixture, give Thermo a try. ![]() Thermo is designed to be easy to use while still providing powerfulįunctionality. Thermo runs on all operating systems which support Python, is quick to install, and isįree of charge. Transport), and the calculation of the same for chemical mixtures (including The retrieval of constants of chemicals, the calculation of temperatureĪnd pressure dependent chemical properties (both thermodynamic and Heat transfer from surroundings to refrigerant è Entropy increases (S2>S1).Ä¡-2': Heat transfer from refrigerant to surroundings è S2' ![]() Since it is a reversible cycle, all four processes can be reversed. It has the maximum efficiency for a given temperature limit. ![]() The difference is in their objectives.Ĭarnot cycle is a totally reversible cycle which consists of two reversible isothermal processes and two isentropic processes. Heat pump and refrigerator cycles are very similar. This process requires a special device called Refrigerator.Īnother device which transfers heat from low to high temperature is a Heat Pump. heat transfer from low to high temperature) cannot occur by itself (Claussius Definition of Second Law). It is a well known fact that heat flows in the direction of decreasing temperature, i.e., from a high temperature region to a low temperature region.Ä«ut the reverse process (i.e.
