[TRNSYS-users] Type 511 dry fluid cooler
Dear Trnsys users,
I`m having trouble with type 511 dry fluid cooler. I want to cool
cooling water coming from type 666 chiller to a setpoint temperature.
To do this I have type 22 feedback controller connected to dry fluid
cooler`s fan control signal.
The system seems to work quite well with constant ambient temperature
but when dry cooler is connected to weather file errors keep coming. I`m
guessing that the problem is the design parameters of the dry cooler.
Those are:
Liquid: 44 C (111.2 F)/ 37 C (98.6 F)
Fluid flow rate: 53,2 kg/s
Design ambient air: 30 C (86 F)
Air flow rate: 104 kg/s
Rated fan power: 50,4 kW
I have tried many different design parameters but nothing seems to work.
Does anyone have ideas how I could get my dry cooler to work properly?
Kind regards,
Markus Hyttinen
