Dear Jeff thank you for your kindness Our experimental prototype heat pump system use ground heat exchanger as heat source and heating and cooling storage for space heating and cooling as heat sink. Our system is like figure of attach file(HP installation .doc) and our heat pump includes desuperheat. and then because type-668 can't model desuperheat, i think type-668 water to water heat pump model you suggest is improper to our heat pump system. Let me know If there is any other water-to -water heat pump model including desuperheat. thank you for your kindness in advance.

The Type 504 model is a water-to-air heat pump model; transferring energy between the working fluid (typically water) and an air stream. In cooling mode, the water stream acts as the heat sink (condenser); rejecting energy from the air stream cooling process and the compressor heat. In heating mode, the water stream acts as the heat source; adding energy from the fluid stream and compressor energy to the air stream. We also sell an air-to-air heat pump model and a water-to-water heat pump model in the HVAC component library addition for TRNSYS. I can provide details if you are interested. I hope this helps, Jeff ********************************************************************************* Thermal Energy System Specialists (TESS) Jeff Thornton 2916 Marketplace Drive Principal Suite 104 Phone: (608) 274-2577 Madison WI 53719 Fax: (608) 278-1475 USA E-mail: thornton@tess-inc.com Web Page: www.tess-inc.com "Providing software solutions for today's energy engineering projects" *********************************************************************************
