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.
Hi my name is Vevek. Im an Mphil student and i have been using trnsys for about 7-8 months now(first time posting here). Long story short i made a trnsys model of my uni with their actual hvac system and implemented a load based chw varible flow control. I'm now trying to calculate the power consumption of the chiller using variable flow control. i See that there are many people here with much experience on trnsys so any guidance or clue is very much appreciated. Thank you very much.
@vevek The power consumption of the chiller should be an output of the Type you're using to model the chiller. For example, in TRNSYS18 in the standard library, the power consumption of the chiller is Output 3 of Type 118 (air-cooled chiller), or Output 5 of Type 142 (water-cooled chiller). You can connect the output to a printer (Type 25) to get the rate of power consumption (kJ/hr) printed at user-defined intervals to a text, .csv, or .xls file, or connect to a printegrator (Type 46) to get the integrated energy consumption (kJ) over a specified period to a text, .csv, or .xls file. Note that you'll have to manually convert the units in post-processing to get the output in kW or kWh. Good luck!
