An error message to this effect will be generated for PCM simulations where the CTF solution method is selected. Note also that the CTF solution algorithm is the only option available for Heating and Cooling design so the phase change effect of the material will not be seen in these calculations.
If you use the CTF algorithm the material will behave as if its PCM option were not selected. The ergonomically designed, small form factor device comes in frustration-free packaging, and takes.

Important note: The Finite Difference solution algorithm must be used to include the effect of material phase change properties in simulations. OBDLink MX+ is an easy-to-use, inexpensive, hacker-proof, lightning-fast Bluetooth OBD adapter that can turn your smart phone, tablet, laptop, or netbook into a sophisticated diagnostic scan tool, trip computer, and real-time performance monitor. A set example PCM datasets is provided with the materials database that comes with DesignBuilder.ĭesignBuilder supports both types of PCM modelling methods provided by EnergyPlus: PCMs are frequently used to reduce the need for mechanical cooling, peak load shifting and improving solar energy utilisation.ĭesignBuilder allows you to enter manufacturers phase change properties in the form of a temperature - enthalpy curve on the Phase change tab of the Materials dialog. The high latent heat storage capacity of these materials works to effectively increase thermal mass which tends to moderate interior temperatures and improve comfort conditions. Some PCM manufactures also provide mats of pure PCM "pockets" which can be included as layers within constructions.īy completing a transition between solid and liquid phases PCMs can absorb large quantities of latent heat. Phase Change Materials (PCMs) are often impregnated into gypsum board, plaster, concrete or other materials in order to increase the thermal storage capacity of ceilings, walls and floors.
