Question details



uluings u VA Packaged Syste (30 degree) ing room is maintained at 24 °C and 50 % relative humidity. In summer, the ambient conditions are 38 C dry bulb and 26 C wet bul is 50 k W and latent heat gain is 10 kW. The return air is mived with the fresh air before enterin the cooling coil in the ratio of 3 to 2 by weight and the supplied air to the room is at 15 C. Draw the layout of the system and show the processes on the Psy chrometric chart. Determivne the followings; (i) the supplied air to the room in kgs. (ii) the mass low rate of return and fresh air in (ii) the refrigeration capucity of cooling coil. and (iv) the apparaitus dew point and cooling coil efficieney b temperature. The space total heat gain
