Description

In the experiment P2.6.3.3, a Mollier diagram, in which the pressure p is graphed as a function of the specific enthalpy h of the coolant, is used to trace the energy transformations of the heat pump. The pressures p1 and p2 in the vaporizer and liquefier, as well as the temperatures Ta, Tb, Te and Tf of the coolant are used to determine the corresponding enthalpy values ha, hb, he and hf. This experiment also measures the heat quantities ΔQ2 and ΔQ1 released and absorbed per unit of time. This in turn is used to determine the amount of coolant Δm circulated per unit of time.
