Heat Transfer Coefficient of Air for Changing Humidity Levels
Heat Transfer Coefficient of Air for Changing Humidity Levels
(OP)
I have an incubator that needs to operate in 10% - 95% relative humidity, non condensing. I am running all my tests in a lab with 40%-45% humidity. Is there a method for me to determine what the effects will be on the internal gradient and warm up times (if any) for this large range of humidity? I would like to avoid going to a chamber for this testing if I can prove that the system will still perform to specification in 10% and 95% humidity levels.
Other relevent information
System internal temperature: 32C to 38C
System external temperature: 15C to 28C

Theoretically, I would expect the humidity levels to affect the heat transfer coefficient since the thermal conductivity of the mixture, heat capacity and density would all be affected.
However, even at 28C and 95% humidity, the water level in the air is less than 8% by volume and less by mass. Thus, its effect would be minor IMO. While the humidity is an important factor in people's perception of warm/cold, it's not as relevant for the heat transfer example you have here.
