Re: [TRNSYS-users] air base collector, air to air HEX and humidifier

Hi Jeff,

Thank you for your response.
Regarding air based PVT collectors, I guess type 50 will be applicable if air is chosen as the working fluid in type 50(I'm not sure).
As for the air to air heat exchanger, it seems that types 760 and 667 are only suitable for low- temperature applications such as the HRV system. Are there any types of air to air heat exchanger type?

Ali,

The documentation for Types 667 and 760 is located in  TESS Libraries --> Documentation --> 06-HVACLibraryMathematicalReference.pdf

There are air-based PVT collectors in the TESS Electrical Library but I believe they are building-integrated.

As for the humidifier, you'll have to see what type of performance data you can find for the bubble humidifier and then use one of the humidifier models that uses the same type of performance map/approach.  The other option is to use Type 42 and create your own performance map.

Dear all,
 
I am trying to simulate a solar system for space heating. I'm going to use air based PVT collectors, air to air heat exchanger and a bubble column humidifier. Regarding air based collectors, type 561 and 539 are only thermal collectors. However, I need air based PVT collectors.
As for air to air heat exchanger, how can I access mathematical descriptions of type 667 and type 760? Are there any types of air to air heat exchanger in TRNSYS 18?
With respect to the bubble column humidifier, what is the closet component to it.
 
I would appreciate it if someone could help me in these cases.
