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 or Post 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.

Warnings when calculating Coefficients for Type402

Hi,

I am trying to calculate the Coefficients for the Type402.

The temperatures for which Q and P are provided by the manufacturer defer from the example. 
Now when I use the EES I get the following warnings (for rows 31 to 54):

The row number (31) is outside the range of the Lookup table in equation JTHETA_cond_out[31]=lookup('WP-Daten';31;1).

The row number (31) is outside the range of the Lookup table in equation JTHETA_ev_in[31]=lookup('WP-Daten';31;2).

The row number (31) is outside the range of the Lookup table in equation Y_n[31]=lookup('WP-Daten';31;5).

The row number (31) is outside the range of the Lookup table in equation P_compr[31]=lookup('WP-Daten';31;4).

The row number (31) is outside the range of the Lookup table in equation Q_dot_cond_out[31]=lookup('WP-Daten';31;3).

 

I don't really understand what it means, but it seems to me, that those lines are not taken into account correctly for the calculation.
How can I fix this? I have attached the file I am using for the calculation.

I also don't understand what values I have to enter for the COP correction values.
Those are set to 0 and I don't find any values in the documentation.
