DRAWING ONE If charged with the responsibility of manually controlling the fan system illustrated in drawing one, what considerations exist? (1) What are you required to achieve? -(A)- A healthy living environment for occupants where the supply air is being directed. -(B)- A comfortable environment in the same location. -(C)- The most efficient energy performance. (2)What components do you have to achieve your desired results? What are the functions of each of the components? -(A)- A supply air fan and a return air fan. The function is to force the supply air into and draw the return air from the occupied space. -(B)- A heating source controlled via a manual heating valve. The function is to provide heat to the system at varying quantities. -(C)- A mechanical cooling source controlled via a manual cooling valve. The function is to provide mechanical cooling at varying quantities. -(D)- Manual dampers enabling your selection of fresh air to varying degrees and rejecting air from the building to varying degrees. The function is two fold. -1- Provide at least minimum ventilation based on the greater demand of either the building code relating to human occupancy or provide exhaust air replacement relating to building operations. -2- Provide ventilation in excess of minimum ventilation requirements to achieve cooling when the outside air temperature is lower than the building temperature. 8.66
