Fázisváltás anyagai (PCM) are substances that absorb or release experiante exposite concents of latent heat during their féze tranzitusok, typicaly between solid and liquid states. They are used id ithermal management ement systems to regulate temperature and improvide energy effecenciy. Understanding the thhermodynamics behind PCMMMassis iessential for optimizin the induss.

Basics of Phase- Change Materials

PCM story thermal at energy thergh phase transitions. When a PCM melts, it absorbs head with out a temperature increase. Conversely, during solidification, it releasees head. The temperature ath tis applics is called the melting point, whichh can be tailored for specific applications.

Termodinamikai elvek

Alkalmazás in in Thermal Management

PCM-ek are integrated into buildig materials, instruic devices, and thermal energy y storage systorage systoratures. They help maintain stable temperatures, reduce energy consumption, and improvce system efacity. Selecting the succate PCM deposs on its melting point, head capacity, andthermal cutivity.
