Re: [TRNSYS-users] Type 665

Arnaud,
In addition to Francois' comment, I am not sure how you are modeling the building but if you are using Type56, make sure that you have set the zone thermal capacitance to a realistic value. The thermal capacitance defaults to 1.2 times the zone air volume, which takes into account only the capacitance of the air in the zone. It neglects the capacitance of furniture and fixtures. Typically, a value of about 5 to 10 times the default is used. Changing that will result in a lot less oscillation for your controller because the zone will respond more slowly (and more realistically) to the heat pump.
Kind regards,
 David

Good morning everyone,

I connected Type 665 ( air/air heat pump) to the ventilation of type56.
However, I don't manage to control properly the Heat pump.

At the moment, the heat pump is control by a type 2 component. But it seems
that there is a problem of information transmission between the heat pump
and the controller.

Enclosed, a file where it can be seen the controller setting and the heat
pump working.

Is it the best solution to connect the heat pump to the ventilation? Should
I use the gains instead?

Best regards,

Arnaud.
