Abstract


In the UK, 40% of energy consumption and carbon emissions come from buildings due to the building development process and Heating, Ventilation and Air Conditioning (HVAC) systems. These systems are used to keep the building temperature within the required thermal comfort zone. Consequently, developing more efficient heating and cooling systems would have a significant impact on reduction of energy consumption. The main purpose of this paper is the reduction of the amount of energy that has been consumed for cooling systems in the UK office buildings during hot summer days by using Phase Change Materials (PCMs) in novel cooling systems such as Thermal Energy Storage Systems. Differential Scanning Calorimeter (DSC) testing has been used to measure the PCM thermophysical properties and ANSYS/FLUENT software has been employed to use these properties and create a steady state simulation of thermal loading at peak conditions inside the building. Eventually, results obtained from the software simulation and empirical equations will be used to calculate heat transfer coefficient for this system.
