Classification of Phase-change Materials: a Brief Review
Year: 2026
Type: article
Abstract: Nowadays, the issues related to the environment, in particular the emission of greenhouse gases and the low usage of the available resources, have become increasingly serious, making it unavoidable to search for alternative and less polluting methods of energy storage which could compensate for the mismatch between energy demand and its production, in terms of time and method. These assumptions lead us to conduct a deeper study on Thermal Energy Storage (TES) in its three distinct types: sensible, latent, and chemical. Phase Change Materials (PCMs) enable thermal energy storage in the form of latent heat during phase transition. PCMs significantly improve the efficiency of solar power systems by storing excess energy, which can be used during peak demand. Likewise, they also contribute to reduced overall energy demand through passive thermal regulation. UZ Hozirgi kunda atrof-muhit bilan bog'liq masalalar, xususan, issiqxona gazlari emissiyasi va mavjud resurslardan samarasiz foydalanish muammolari tobora ahamiyati oshib bormoqda. Bu holat energiya ishlab chiqarish va unga bo'lgan talab o'rtasidagi vaqt hamda usul jihatidan tafovutni bartaraf eta oladigan, atrof-muhitga kamroq zarar yetkazuvchi muqobil energiya saqlash usullarini izlashni zaruriyatga aylantirmoqda. Ushbu omillar bizni issiqlik energiyasini saqlash tizimlarining uchta asosiy turi bo'yicha chuqurroq o'rganishga undaydi. Fazaviy o'zgaruvchi materiallar faza o'zgarishi jarayonida issiqlik energiyasini yashirin issiqlik shaklida saqlash imkonini beradi. Fazaviy o'zgaruvchi materiallar ortiqcha energiyani saqlash va uni talab yuqori bo'lgan paytlarda ishlatish orqali quyosh energetikasi tizimlarining samaradorligini sezilarli darajada oshiradi. Shuningdek, ular passiv termoregulyatsiya orqali umumiy energiya talabini kamaytirishga ham hissa qo'shadi.
