SWEP is a world leading supplier of brazed plate heat exchangers for HVAC and industrial applications. Designed to make the most efficient use of energy, material, and space, the technology is quickly winning ground around the world, with SWEP at the ... 2.1 The pressure enthalpy diagram SWEP The pressure enthalpy diagram (log P h diagram) is a very useful tool for refrigerant technicians. First, an explanation of how the diagram is built up is given, and then its use is describ ed. Figure 2.1 shows the principle of a log P h diagram, and indicates the refrigerant's various thermodynamic states. This diagram can be seen as a map of ...

Title: mollier_chart_met.xls Created Date: 11 10 1999 5:42:45 PM Reading Thermodynamic Diagrams How to Read a Pressure Enthalpy Diagram In chemical engineering, it is often necessary to know how properties like pressure, enthalpy, volume, and entropy relate to each other at a certain temperature. A Pressure Enthalpy Diagram provides this information but can be cryptic to decipher. What you need to know: Liquid vapor dome region Reading Volume from ln P H diagram Figuring out the vapor fraction in a ln P H diagram. VOLUME (intensive) units=cm^3 mol. grey=lines of constant volume. Volume lines are upward sloping lines. The volume lines are usually flatter in slope than entropy lines. However, at lower enthalpies, the volume lines become steeper. The volume values will not change that much from line to ... HET H LOG P DIAGRAM BASISBEGRIPPEN |authorSTREAM HET KOUDEPROCES EN HET LOG P H DIAGRAM: HET KOUDEPROCES EN HET LOG P H DIAGRAM In een log P H diagram kan het verloop van een koudeproces worden gevolgd: Verdampen van 4 naar 1 In de verdamper verdampt alle vloeistof doordat het warmte kan opnemen uit het te koelen object. Skew T log P diagram A skew T log P diagram is one of four thermodynamic diagrams commonly used in weather analysis and forecasting. In 1947, N. Herlofson proposed a modification to the emagram that allows straight, horizontal isobars and provides for a large angle between isotherms and dry adiabats, similar to that in the tephigram. Tutorial: Pressure Enthalpy Diagrams | AIChE If a lecture left you in the dust, or your textbook just isn't clear to you on the subject of pressure enthalpy diagrams, check out this tutorial. This video explains the parts of a pressure enthalpy diagram for a single component system and discusses how enthalpy depends on pressure for water. Thermodynamic cycle Industrial Heat Pumps The thermodynamic cycle. The log p h diagram shows a cycle for a mechanical heat pump. The points represent the different components of the heat pump. In this diagram a heat pump with a condensation temperature of 80 °C and an evaporation temperature of 40 °C is taken as an example. Partition coefficient The partition coefficient, abbreviated P, is defined as a particular ratio of the concentrations of a solute between the two solvents (a biphase of liquid phases), specifically for un ionized solutes, and the logarithm of the ratio is thus log P.: 275ff When one of the solvents is water and the other is a non polar solvent, then the log P value is a measure of lipophilicity or hydrophobicity.
