It is required to maintain an air$-$conditioned hall at $280$C DBT and $200$C WBT$.$ Ifhas sensible heat load $45\mathrm{.}4$KW and latent heat load of $16\mathrm{.}5$ KW$.$ The air suppliedfrom outside atmosphere at $390$C DBT and $280$C WBT is $22$ m$3/$min$,$ directly in toroom through ventilation and infiltration. Outside air to be conditioned is passedthrough the cooling coil whose apparatus dew point is $140$C$,60$ percent of therecirculated air from the hall is mixed with the conditioned air after the coolingcoil.
