Utilities
Use a properties block to model preset fluid
properties in a two-phase fluid network. The
default working fluid, specified in Two-Phase Fluid Domain, is used if you do
not specify the network fluid properties. You can
use either the Two-Phase Fluid Predefined Properties
(2P) block, or the Two-Phase
Fluid Properties (2P) block from
the Foundation library. For information on how to
generate fluid property tables from REFPROP or
CoolProp database, see twoPhaseFluidTables.
Use a P-H Diagram (2P) block to plot a system pressure-enthalpy diagram.

Featured Examples
Residential Refrigerator
Models a basic refrigeration system that transfers heat between the refrigerant two-phase fluid and the environment moist air mixture. The compressor drives the R134a refrigerant through a condenser, a capillary tube, and an evaporator. An accumulator ensures that only vapor returns to the compressor.
Refrigeration Cycle (Air Conditioning)
A refrigeration cycle for a home air conditioning system. See Model a Refrigeration Cycle for the recommended steps to build this model in the two-phase fluid domain.
