Preset fluid properties for two-phase networks

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.
