Pressure Enthalpy Diagram. The first step is to determine the mass flow of refrigerant through the evaporator. Therefore h2 h1 pressure enthalpy chart the ideal vapour compression cycle consists of two constant pressure process and one constant enthalpy process.
This video explains the parts of a pressure enthalpy diagram for a single component system and discusses how enthalpy depends on pressure for water. The pressure enthalpy diagram log ph diagram is a very useful tool for refrigerant technicians. The area below the saturation lines for liquid and gas a cp b in figure 21 represents the conditions where the refrigerant can change its state of aggregation from liquid to gas or vice versa.
Take r 22 pressure enthalpy diagram figure 1 1 draw a condensing temperature line of 105ºf an evaporative temperature line of 20ºf constant throttling line from the 105ºf condensing liquid to 20ºf line to represent the expansion and draw the line of constant entropy from saturated 20ºf to condensing temperature of 105ºf this line.
Pressure enthalpy p h diagram for r 22 simplified. This video explains the parts of a pressure enthalpy diagram for a single component system and discusses how enthalpy depends on pressure for water. 3 days ago jewellery ph diagram r22 is really a really adaptable piece of jewellery producing products and there are plenty of. The pressure enthalpy diagram log ph diagram is a very useful tool for refrigerant technicians engineers and researchers.
