Mollier part 3. The Mollier Chart also called enthalpy entropie chart the h-s chart or called the psychrometric chart is a chart devised by Richard Mollier in 1904 that expands the enthalpy against entropy. The application can be used to make calculations of air treatment processess such as heating cooling and humidifying.

Mollier diagram luleå university of technology may 6th 2018 - dew point tdp the dew point is the temperature at which water vapor starts to condense out of the air the temperature at which air becomes completelyAir Conditioner Compressor Troubleshooting amp Repair May 2nd 2018 - Air Conditioner Compressor Troubleshooting The. Cooling capacity normally is determined at 80F dry-bulb67F wet-bulb indoor and 95F dry-bulb outdoor temperatures. Explanation of the glide The azeotropic mixtures such as R404A have a similar behaviour to the single refrigerants such as R134a.

They condense and evaporate at an almost constant temperature. Thermocompressor operations on a Mollier Diagram High pressure steam called motive steam in expand in the nozzle-process 1-2 this being a isentropic entropy constant process. The transformation between Mollier diagram and psychrometric diagram.

This Mollier diagram is similar to that presented in reference 1 __ but the ramges of temperature and pressure are extended _ to vrdues suitabIe for use in turbojet-engine-compressor problems. The Mollier chart is also very helpful. Due to frictional losses in the middle the actual process of expansion achieved is represented by process 1-2.

This diagram has a series of constant temperature lines constant pressure lines constant quality lines and constant volume lines. The air condition with dry bulb temperature 21 OC and relative humidity of 50 is indicated in the table below Moliier. Proce during which evaporative cooling occurs a Mollier diagram for air saturated with water vapor vim developed.

Read the air density by following the slanting orange lines in the diagram. A Mollier diagram with the changes in enthalpy of the component parts is shown for the turbine. Table 47Draw in the Mollier diagram at the 14C point of the saturation curve a the state change line of the adiabatic humidification and b an auxiliary line associated with the wet bulb temperature measurement by means of which the state can be defined.

The coordinates of the Mollier diagram Fig. This is a quick no-nonsense guide to using the Mollier diagram. The solution of the work compression part of the compressor selection problem is quite accurate and easy when a pressure-enthalpy or Mollier Diagram of the gas is available see Figures 18-24AHThe charts in the figure present the actual relationship of the gas properties under all conditions of the diagram and recognize the deviation from the ideal gas laws.

The Mollier diagram is a is plot of enthalpy h versus entropy s as shown in Fig. The Mollier diagram is a variant of the psychrometric chart. It is also known as the h-s diagram.

Air density is the specific gravity measured in kgm. Loss coefficients are defined and numerous calculation methods are outlined. While weve done our best to make this as easy as possible to understand it does require some knowledge about what the lines stand for so if youre unfamiliar with the diagram please read the first and second parts of this blog.

The diagram below can be used to determine enthalpy versus entropy of water and steam. Axis to the extreme left. Mollier diagram Fig 5 42.

The Mollier diagram is used only when quality is greater than 50 and for superheated. Mollier diagram Pro is a powerfull application based on the H-S diagram or Mollier diagram. Air temperature t The vertical.
