Welcome to the TRNSYS Users Forum.

The forum is a place where people can interact and have discussions about different topics involving the use of the TRNSYS software package. Here you can post topics for discussion or questions on using TRNSYS and get advice from other users or TRNSYS experts. This forum is not intended for detailed technical support. Users should contact their distributor’s hotline for such assistance.

Some tips for success on using the forum:

  • Follow the Forum Rules posted in Forum Administration.
  • There are categories for different types of topics and questions. Post your topic or question into the proper category.
  • Before posting a topic or question search the existing topics  (and the TRNSYS Users listserv archive) to see if a similar topic or question has already been answered.
  • Use a descriptive topic name. Don’t use attention getting subjects, they don’t get attention and only annoy people.
  • State the version of TRNSYS and which add-ons your are using.
  • Include enough specific details for your topic of question to be answered. Just posting “Why am I getting an error?” without describing the specific error and what you are trying to do when you get the error will not receive a response that fixes your issue.
  • Remember when people help you, they are doing you a favor. Be patient, help people out by posting good descriptions of what you need help with, and be polite even if a response does not solve your issue.
  • Moderators may edit your post for clarity or move your topic to a more appropriate category.

Latent gain from plants

Dear Users,

I am modelling a greenhouse. and i have developped a type that is able to estimate the sensible heat and latent heat from plants.

For my current model, i add the sensible heat as convective gain and the latent gain as absolute humidity. 

my question is : does Type 56 consider the latent heat as i added the absolute humidity or should i add also the "estimated latent heat from my new Type" as convective gain ?

 

Thank you.

Mohamed

Type56 takes latent gains in kg/h of water so as an absolute humidity gain.

As a side note, there is an evapotranspiration model included in the latest version of the TESS Libraries. The underlying algorithm in that model is technically for outdoor plants but I have used it a number of times for greenhouse modeling and gotten reasonable results.

kind regards,

 David

Thank You David,

 

But my question is : Does TYPE 56 accounts for the heat variation when i add the absolute humidity or not ? 

because if i add 10 kg/hr or 100 there is no effect on the air temperature.

 

kind regards,

Mohamed.
