*5.4. Discussion*

With respect to the case without faults, Tables 11 and 14 indicate the effects of the occurrence of fault 1 (velocity of supply air fan kept reduced at 20% instead of the nominal value of 50%):


refrigerating system (37%), the heat pump (19%), the steam humidifier (32%), and the supply air fan (91%).

With respect to the case without fault, Tables 11 and 14 demonstrate the effects of the occurrence of fault 2 (velocity of return air fan kept reduced at 20% instead of the nominal value of 50%):


With respect to the case without fault, Tables 11 and 14 show how the occurrence of the fault 3 (the opening percentage of the valve regulating the flow to the post-hating coil kept closed instead of allowing its normal operation in the range of 0 to 100 according to the automatic control logic):


With respect to the case without fault, Tables 11 and 14 highlight how the occurrence of the fault 4 (the opening percentage of the valve regulating the flow to the cooling coil kept closed instead of allowing its normal operation in the range of 0 to 100 according to the automatic control logic):


With respect to the case without fault, Tables 11 and 14 indicate how the occurrence of the fault 5 (the opening percentage of the valve regulating the flow to the steam humidifier kept closed instead of allowing its normal operation in the range of 0 to 100 according to the automatic control logic):
