<DIV><FONT face=Arial size=2>Dear TRNSYS users,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>for my my year-long simulation I need to use a
air-water heat pump, whose role is to supply temperature (at 50 and 7°C in
winter/summery operation) and flowrate to the type 673 fan coil. I have Standard
TRNSYS and TESS Libraries but I don't understand which is the type that models
the heat pump. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1) Maybe type 655 can simulate
winter operation but I'm searching for a type that I can use to cool and
heat the fluid and not only cool it.</FONT></DIV>
<DIV> </DIV>
<DIV>2) If I use type 655 I must supply 2 two
external data files. The first data file contains ratios of the capacity to the
rated capacity and the COP to the rated COP as functions of the chilled water
set point temperature and the ambient temperature; the second file must contain
the fraction of full-load power as a function of the part-load ratio on the
machine. But for my heat pump I have only the data presented in the catalogue
(ie rated cooling capacity, rated heating capacity, COP, total fluid flow
rate... see in attachment)!!</DIV>
<DIV> </DIV>
<DIV>
<DIV><FONT face=Arial size=2>I hope that someone can help me... whichever
description in TESS libraries is absolutely devoid and I don't know how continue
my work.</FONT></DIV>
