which of the following are challenges that need to be addressed when a single speed blower motor is used on a zoned air - conditioning system?\no a. increased airflow, reduced air velocity, high system operating pressures\no b. reduced airflow, lower system operating pressures, condenser coil freeze - ups\no c. reduced airflow, increased noise, evaporator coil freeze - ups\no d. increased airflow, increased noise, evaporator coil freeze - ups

Answer

Brief Explanations:

When a single - speed blower motor is used in a zoned air - conditioning system, the inability to adjust speed can lead to reduced airflow as it may not meet the varying demands of different zones. This can cause increased noise due to inefficient operation. Also, reduced airflow can lead to evaporator coil freeze - ups as the heat transfer is affected.

Answer:

C. Reduced airflow, increased noise, evaporator coil freeze - ups
