Thank you for your suggestion. I understand the idea to have a lump capacitance to represent the zone and then control its temperature. However, I only know the type 690 which input refers to an air flow rate. Is there a corresponding type
to use in a water-water heat pump, so with a water flow rate?
Thank you again.
kind regards,
Jacopo
Jacopo,
This is a little bit tricky; the problem is that the loads you have are presumably instantaneous heating and cooling loads. If your delivery device were something without a lot of thermal mass (like zonal heat pumps or some fan coils) then I would recommend
that you impose the loads directly onto the liquid stream. However, the radiant floor has a lot of thermal mass of its own. I think the best approach would be to impose your loads on a lumped capacitance that is tuned to mimic the zone. Then you can define
a radiant floor using Type653 in order to control the temperature of the lumped capacitance that has your original building loads imposed upon it.
kind regards,
David

Dear trnsys users,
I’m simulating a ground water source heat pump for residential conditioning system. I have the hourly load profile of the building and i’m not using the type56. However my system has radiant floor as emmiter and
i see that it’s possible to use type653 only with building type56. I’m looking for a way to simulate this kind of implant, i try with type 690 but i’m not sure it’s right for a water system.
Any suggestions to simulate my implant without type56?
Thank you every all
Best regards,
Jacopo Valente
