WebHess's law is a fundamental principle in thermodynamics which states that the enthalpy change of a chemical reaction is independent of the pathway between the initial and final states. In other words, the enthalpy change of a reaction is the same whether it takes place in one step or in a series of steps. Web1, 2] enthalpy of formation based on version 1.122 of the Thermochemical Network This version of ATcT results was partially described in Ruscic et al. [], and was also used for the initial development of high-accuracy ANLn composite electronic structure methods [].
WebOct 11, 2024 · Propane heat pump hits new efficiency record. 11 Oct 2024. GERMANY: Engineers in Germany developing a propane-based refrigeration circuit for heat pumps are said to have achieved a heating capacity of 12.8kW with only 124g of propane. A prototype of the circuit, part of the project LC150 (Low Charge 150g), is being shown by the … WebOverall, the working fluids propane, propene and their mixtures show the best performance. For applications where indoor heat pumps are required, the HFO R454C, R457A and R516A offer efficient alternatives whose efficiency can be increased by integrating an internal heat exchanger into the refrigeration cycle.
