Jak działa klimatyzacja | Wykres ciśnienie-entalpia i obieg Lindego
In this video, we discuss one of the most important tools in refrigeration and air conditioning: the logarithmic pressure-enthalpy chart, also known as the log p-h chart. Using this chart, we show how to read the basic parameters of a refrigeration system and how to understand the relationships between pressure, temperature, enthalpy, and the state of the refrigerant. Step by step, we explain what the saturation dome, saturated vapor, saturated liquid, and liquid-vapor mixture are. Then we plot the Linde cycle on the chart and discuss the four key processes that take place in a refrigeration system: evaporation, compression, condensation, and expansion. The video also shows why temperature and pressure remain constant during evaporation and condensation, as well as what superheating and subcooling mean in practice. This material is especially useful for those who want to better understand how air conditioning, refrigeration, and systems based on the refrigeration cycle work. 👉 Be sure to leave a thumbs up so we know you enjoyed the video!
