thanks
for your answer and for the screen capture of the system but I have some
doubt concerning the use of the type 504 (or 505) to model the air to
water heat pump. The type is designed to model a water to air
heat pump so I can't use it to provide the required heating or cooling to
the flow stream! How can I to resolve the problem? I think that isn't
possible that in standard TRNSYS or in TESS libraries there isn't a
similar type! Maybe it's the type 172 or 201 "Electric compression
Heat Pump (M. Hornberger or M. Wetter, T. Afijei)" available for
sale in

It's exact?
An air to water heat pump acts exactly like a water to air heat pump for
modeling purposes. All you have to do is realize that the
air-cooling mode of a water to air heat pump is the HEATING mode of a air
to water heat pump. The only difference is that the catalog data
for the models will have slightly different temperature ranges. I
have used our water-to-air models for water-to-air devices many times
with little problem.
