Example $8$: An air conditioning system supplying air to a space with a sensible heat load of $14$ kW and a latent heat load of $9$ kW has a cooling coil and a bypass path as shown schematically in Fig. The db$-$temperature of the space is maintained at $26C.$ The dry air mass flow rate of supply air is $1\mathrm{.}2k\frac{g}{s}.$ Outdoor ventilation air at $34C$ db$-$temperature and $50\%$ relative humidity is introduced into the system with a dry air mass flow rate of $0\mathrm{.}26k\frac{g}{s}.$ The air leaving the cooling coil is fully saturated at a db$-$temperature of $6C.$ The pressure is constant at $101\mathrm{.}3$ kPa $.$ Determine $($i$)$db$-$temperature and relative humidity of the supply air to the space,

$($ii$)$the wb$-$temperature of the space,

$($iii$)$the temperature of the air entering the cooling coil, and $($iv$)$ the refrigeration capacity of the cooling coil.
