Hi all,
Iam getting unreasonable
total cooling results (around 2 RT) for a house under semi
arid climate (Baghdad, Iraq), even after using maximum cooling
without any constraints, e.g. schedules. Besides, I have zero
demands for heating in the winter.
My house consists of 4 beds, 2 baths, 1 WC,
corridor, living, dining, kitchen, storage and machine rooms, and I assumed these schedules:
1-QCCUPATION:
Bedrooms from 0-7 am is occupied at a rate one
person for each bedroom
Kitchen
from 7-8, 12-14 & 19-20 at a rate 2 persons, same
schedule is applied for
the dining room with rate 4 persons (which am not sure about
it)
Living room from 7-24 at rate 4 persons (also
here am not sure about that)
As for the machine room, I assumed the heating
and cooling are ON 24 hours.
2- INFILTEATION
Constant value equal to (0.5) ACH
3- VENTILATION
Constant value at rate 2 ACH for bathrooms and
WC, and 5 ACH for the kitchen according to the its occupant scheduale.
4-COOLING AND HEATING
Cooling is ON for zones at occupation times when
the temperature rises above 25 deg C, otherwise it works when
temperature up to 30 deg C for unoccupied times.
Heating is ON when temperatures drop below 22
for occupation and 15 for unoccupied
5- HEAT GAIN
Kitchen 24 hr. Fridge +
stove when it occupied
Living room has
2 terminals
Unfortunately, I don't know what are the gains
from (absorption chiller) in the machine room
Are my assumptions true? And what I missed?
Could you please help me
Kind regards,
Shahen
