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.
- I don't have any information for rated fan power according to the design airflow condition for the cooling tower. Please suggest some thumb rule for fan power for the cooling tower for type 510.
- I also want to know how to calculate the rated capacity of the cooling tower for cost analysis. Are the values at design conditions giving m_des*Cp* (Tdes_in-T_des_out) sufficient to calculate the capacity, or should I be modifying it with any other factors?
My recommendation would be to look around online and see if you can find a cooling tower of similar size and take its specifications. Baltimore Air Coil ( http://www.baltimoreaircoil.com/pss) provides a really helpful tool online for which you can enter your design requirements and get back the specifications of a tower that will meet them (including both fan power and rated/design capacity at a particular design wetbulb temperature). For the fan power, another good resource is ASHRAE Standard 90.1 (and its User Guide). Appendix G contains a lot of useful rules of thumb for setting things like fan power based on knowing only the flowrate.
kind regards,
