  • <\/i><\/span>
    PVT modules generate electricity and provide low-temperature thermal energy.<\/div><\/li>
  • <\/i><\/span>
    Thermal energy raises the evaporator temperature of the heat pump, increasing the COP coefficient.<\/div><\/li>
  • <\/i><\/span>
    The heat pump produces both heat and cooling.<\/div><\/li>
  • <\/i><\/span>
    Surplus electricity can be used for Ice Energy Storage (ICE).<\/div><\/li><\/ul><\/div><\/div><\/div><\/div>

    Ice Energy Storage (ICE)<\/h2><\/div>

    ICE uses the phenomenon of latent heat during a phase change.<\/p>\n

    The energy required to transform water into ice at 0\u00b0C is approximately 80 times greater than the energy stored in water as sensible heat.<\/p>\n

    Compared with water storage:<\/p>\n

      \n
    • 5\u20137 times higher energy density,<\/li>\n
    • stable operating temperature of 0\u20136\u00b0C,<\/li>\n
    • compact system design,<\/li>\n
    • the possibility of short-term and medium-term load shifting.<\/li>\n<\/ul>\n

      Ice energy storage can take place during periods of surplus energy from PVT or when electricity prices are low.The system does not require boreholes and is not dependent on geological conditions. <\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>

      Passive cooling \u2013 ICE discharge<\/h2><\/div>

      The result is very low electricity consumption and reduced operation of energy-intensive cooling units during peak demand.<\/p>\n<\/div><\/div><\/div>

      During discharge:<\/h4><\/div>
      • <\/i><\/span>
        melting ice releases water at a temperature of 0\u20136\u00b0C,<\/div><\/li>
      • <\/i><\/span>
        cooling is carried out by circulation pumps,<\/div><\/li>
      • <\/i><\/span>
        the heat pump compressor does not operate.<\/div><\/li><\/ul><\/div><\/div><\/div><\/div>

        HVAC support and system flexibility<\/h3><\/div>

        Ice Energy Storage (ICE) acts as a dynamic HVAC power buffer, quickly absorbing peak loads and stabilising the operation of the entire installation.<\/p>\n<\/div><\/div><\/div>

          \n
        • Ice Energy Storage enables rapid release of thermal or cooling power in under 6 hours, allowing the system to absorb peak loads and sudden increases in demand without the need to immediately start additional cooling units.<\/li>\n<\/ul>\n<\/div>
            \n
          • ICE acts as a dynamic power buffer for the entire HVAC installation \u2013 relieving compressors, stabilising system operation, and potentially serving as emergency cooling in industrial applications.<\/li>\n<\/ul>\n<\/div>
              \n
            • At the same time, energy from PVT can be accumulated in the form of ice during periods of surplus production or low tariffs, and then used when demand is higher or energy prices are higher. In this way, the variable PV profile becomes a controllable profile, and the facility can actively respond to grid price and load signals. <\/li>\n<\/ul>\n<\/div><\/div><\/div>
