Abstract

Current air conditioning systems consume significant amount of the electricity particularly during the peak period leading to significant fossil fuel energy consumption and carbon emissions. Thus there is a need to develop a new technology that consumes less energy and environmental friendly. Liquid nitrogen has been acknowledged as energy storage vector with high energy density. The current study investigates the feasibility of using the store cold energy in the form of liquid nitrogen to produce cooling and power for domestic building. A thermodynamic analysis of a combined cryogenic system fuelled by liquid nitrogen was carried out using Matlab integrated with Refprop software. Results showed that, using LN2 to meet the cooling demands at the peak period is feasible and promising. The proposed system recovered 81% of the energy stored in LN2 and with the current LN2 prices it achieved saving of 30% compared with the conventional AC system but the widespread of this technology can lead to further reduction of LN2 prices leading to significant savings of 81% and.
