Heat-loss calculation is for to keep up the room at design temperature. It is necessary to add %7-30 for start heating, depends on non-heating time. You need specific heat of the materials in room and room construction, for accuracy in calculation.
May be a perimeter coridor to exhaust, instead of the nursing area, from surgery suits. Individual supply air and exhaust air for the nursing area is more reliable way.
Thanks Drazen. I have wanted to alternative recommends. I worked in different healt care jobs. For only polyclinics (exam rooms and corridors), which system do you prefer? I think induction units in the exam rooms, and VAV in crowded corridors.
I am interested in a building, 140 m tall. Boiler room and the chimneys are out of the building. How can I calculate the chimney distance from the building and the chimney tall?
With such as this equipment, you can not reach your design conditions. You can reach more dry bulb temperature and less RH. For example, if your design conditions is 24C-%50RH, your end conditions may be 27C-%35RH.
Thanks for quick responce.
But, I mean only starting position, not normal operation.
When supply and return fans begin to start, high current occurs. to prevent the fan motors, some consultants advice closed damper starting, others advice open damper starting. Please, declare your opinion.
Thanks.
