b. An air - conditioning system takes in air at a volumetric flow rate of
230(m^(3))/((m))in,101.325kPa,30\\\\deg C
and
70%
relative humidity and delivers it at
22\\\\deg C
and
50%
relative humidity. The air flows over the cooling coils, where it is cooled and dehumidified, and then over the resistance heating wires where it is heated to the desired deliver temperature. Then the refrigeration system operates at steady state condition with refrigerant
R410a
is used as a working fluid. Saturated vapour of R410a enters the compressor at
-10\\\\deg C
and leaves the condenser as saturated liquid at 26 bar. Sketch the process using psychrometric chart. Evaluate i . the mass flow rate of the dry air
