Techno-economic analysis of a hybrid solar PV-grid powered air-conditioner for daytime office use in hot humid climates - A case study in Kumasi city, Ghana

摘要

Air-conditioners are the highest energy consuming appliances in the offices of businesses, public and commercial buildings in hot humid climates. In Ghana, survey conducted indicates that 60-80% of electricity used in offices of public and commercial buildings is for air-conditioning. Many hot climates, and Ghana in particular, are endowed with high solar irradiations. The need for daytime office space cooling is actually as a result of high solar radiation levels.
