Abstract

Improved energy efficiency in buildings is the key element to reduce the
greenhouse gas emissions while contributing to energy security. Underfloor
heating is a more efficient and economical method for home heating with
improved thermal comfort than any other heating methods. Due to the lowtemperature heating source requirement the underfloor heating is widely
accepted as the most efficient form of heating. Heat pumps are energyefficient equipment to provide low-temperature heat source which is
suitable for underfloor heating applications. Phase-change materials
(PCMs) are attractive for use in thermal energy store for underfloor heating
applications due to their high-energy storage density over a small
temperature range, therefore allowing the air source heat pump to operate
during winter warmer afternoon ambient air conditions or in an electricity
tariff management mode. A numerical simulation model has been validated
and used to analyse the thermal performance of PCM-layered underfloor
heating under different heating modes. Different layouts of the underfloor
heating pipes with PCMs as floor mass material were analysed for realistic
diurnal temperature boundary conditions and temperature distribution was
predicted
