Solar PV Powered Air Conditioning Unit for a Train

File Size: 2.36 Mb

The objective of the present work is to design and select an air conditioning unit for a train coach using solar energy as the only source of energy, instead of the conventional system which is powered by a diesel generator.

The work is based on the estimation of air conditioning power consumption during 10 hours. An extensive study was done on calculating coach cooling load and sizing a suitable PV system.
Two options were considered: the first one was to use an alternating current PV system and the second one was to use a direct current PV system. Then an economical feasibility study was conducted to compare between the two systems and to study the overall economy of the proposed solar air conditioning unit. The first option was found to be the most economically feasible.
