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
