Hey,
Sorry I am new to this specific field and I need to do COP test methodology for an Evaporative Condenser.
Is it enough to measure only the following:
Temperature of the refrigerant entering condenser (steam under 80 Celsius)
Temperature of the refrigerant leaving condenser (liquid over 0 Celsius)
Refrigerant flow (liquid)
Power consumptions (condenser's fan and condenser's pump)?
I don't understand why I should also need to measure:
Wet bulb temperature (outside air entering condenser)
Dry temperature (outside air)
Pressure of refrigerant entering/leaving compressor and condenser (under 30 bar).
Power consumptions (compressor)?
Is there something else I need to measure?
And what measuring equipments should I use and how to do the measurements.
Designing system
I also have a problem choosing the compressor. The smallest evaporative condenser is almost 200% too big. Do I also need to choose a bigger compressor because of the big condenser and does the too big condenser affect badly the compressor and other devices?
Thank you very much for your help in advance!
