Thermal energy storage at temperatures in the range of 100 °C-250 °C is considered as medium temperature heat storage. At these temperatures, water exists as steam in atmospheric pressure and has vapor pressure. Typical applications in this temperature range are drying, steaming, boiling, sterilizing, cooking etc.
In 2005, 65% of building energy consumption came from rural areas [ 5 ]. Due to urbanization, the energy consumption of rural buildings accounted for 25% of total building energy consumption in 2017 [ 6 ]. Owing to poor design and technical constraints, the current energy-savings performance of rural houses in cold regions is low [ 7 ], and …
