Mechanical Engineering

A 2.5 TR split unit is to be powered using solar photovoltaic(PV) cells. Assume the cooling unit has a COP = 3, the solar panelconverts only the direct solar radiation (i.e. neglect diffusepart) & the conversion energy efficiency is 30%, calculate therequired surface solar panel area (m2) and the saving in themonthly running cost (S.R./month) assume 8 hr’s unit dailyoperation & the power charge is 0.18 S.R/kW-hr. To calculatethe solar radiation, use the following data: Location: Jeddah, l =21.67o, L = 39.15o, CN = 0.7 Day: June 21st Solar hour (h) = 37.6othe solar panel is facing south with a surface tilting angle = 23ofrom the horizontal.
