Q3/Answer by true or false : 1) All water systems using fan coil units are suitable in buildings requiring individual room control and consume less space compared to all air systems. 2) All air conditioning systems make use of an economizer. 3) With 100 % re-circulated air, some time, the room ADP is equal to coil ADP and the load on the coil is equal to the load on the room. 4) The sensible load affects dry bulb temperature, while the latent load affects the moisture content of the conditioned space. 5) A single zone, single duct, constant volume system can be used either for cooling or for heating, but not for both cooling and heating simultaneously.

RESENDING QT - NEED ANSWERS TO REMAINING 3 QTS 1.4, 1.5, 1.6 1.1 Determine the electrical power supplied to a boiler when the temperature of the entering water is 20 C and the exiting temperature is 89 C. The flow of.the pressured water is 2 Kg/s. There is a negligible pressure drop through this boiler and it operates at a constant pressure of 3 bars. The specific heat is c = 4,370 J/(Kg K). There is a 1.5(105 ) W rate of heat loss from the boiler during this process to a surrounding at 293.2 k. Consider steady state conditions. 1.2 Calculate the total rate of entropy production in Problem 1.1. 1.3 Calculate the total rate of exergy destruction (W) in Problem 1.1.
