Avapour compression machine circulates nh3; the condenser and evaporator pressure being 1170kpa and 270 kpa respectively after isentropic compression. the vapor compression refrigeration system working on r-12 having condensing temperature of -10°c. if the suction temperature is increased to +10°c, with the same condensing temperature, calculate (i) c. o.p. (ii) power/ton for each conditions. assume simple saturated cycle and discuss your result.
