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.

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.

Type143 -query on correction factor

Hi all,

I am creating WSHP and I got stuck at one point regarding the cooling correction factor. Below I have pasted the cooling correction factor data for a ground loop heat pump. What do I use in the correction factor for instances in asterix saying that the sensible cooling is equal to the total capacity. I have not checked the source code yet and I was wondering what factor to put in those asterixed places so that trnsys understand that the sensible capa. at those conditions will be equal to total capa.

 

Thanks in advance.

Hi Abir,

 

I am working on WSHP on TRNSYS 18 as well. However, the WSHP manufacturer's data I found don't have the data required in Type 919, such as the sensible cooling capacity and correction factor data.

 

Just wondering could you please share the model number of the WSHP you are using? Or is it possible to share the manufacturer's

data of the WSHP that you showed in the screenshot? Thanks in advance.

 

Kind regards,

Jingjing

Thanks for your reply.

For your question, I have similar correction factor data. What I understand was that the multipliers (i.e. correction factors) of the sensible cooling capacity are equal to that of the total cooling capacity at the conditions given in the asterisk area.

Kind regards,
Jingjing
