Unfortunetaly I don´t have access to the TESS library. I´m sorry
but I dont understand what you were meaning with: <i>"If you do
not, then I would imagine that you might be able to come up with
a simplified set of equations that would give you the gains to
the space that you need.
"</i><br>
<br>
Do you mean that I use the GAINS to adjust the radiative and
convective part ? But how to take the room temperature into
account by also considering the outlet temperature out of my
storage ?? Isn´t there also a way to work with HEATING INPUTS ?! I
still dont have an idea how to cover my heat demand by using the
outlet temperature :( <br>

Ideally, you need a radiator model that will deal with the water
side, take room temperature from Type56 and output the convective
and radiative gains to the space as outputs. Such a model exists
in the TESS HVAC library for Trnsys17 if you have access to it
(Type1231). If you do not, then I would imagine that you might be
able to come up with a simplified set of equations that would give
you the gains to the space that you need.

thanks a lot. I´ll have a look.
<br>
<br>
Could you please help me in another case. My plan is to connect
the HP to a storage tank and then giving a temperature from the
storage (type4) to my type56... How can I realize that my type
56 can be heated to achieve a constant room temperature of e.g.
20°C ?!
<br>
<br>
Someone told me that I must use HEATING and then INPUT... but
what if i would like to simulate a simple radiator with a simple
inlet temperature of e.g. 55°C.
<br>
<br>
Do you understand my problem? I dont know how to cover my heat
demand out of the storage.
<br>
<br>
Thanks in advance
<br>

I would recommend that you look online at manufacturer's
sites for similarly sized heat pumps. Trane and Carrier both
have significant amounts of performance data in the product
literature parts of their sites. You can probably get a good
estimate of the flow rates on both the condenser and
evaporator sizes from them.

I´m working with the heat pump non-standard type 401 and try
to display an air-source heat pump.
<br>
<br>
I dont have typical values for the Input 2 (evaporator mass
flowrate) and Input 4 (condenser mass flowrate).
<br>
The only real connection I´m using is the dry bulb temp,
coming from type 15, as the evaporator inlet temperature.
For the massflowrates I would like to assume constant
values.
<br>
<br>
How can I adjust an outlet condenser temperature of e.g.
55°C. Just about the massflowrates ?!
<br>
<br>
Does anyone have experience with heat pump mass flow rates?!
I guess it´s not necessary to have expieriences with Type
401.
<br>
<br>
I´m thankful for any advices.
