Room not found in design database

Claire Mackenzie — Wed, 03 Jan 2018 12:11:58 GMT

Hi,

I'm currently working on a model and have deleted a room, however, the following message has came up... "room not found in database. To prevent possible database corruption design database will now shut down" and the project is now inaccessible. This is causing a major problem as I have taken the model quite far and now I cant access it. Can this problem be resolved without having to start again?

Kind regards,

Claire Mackenzie

Internal Heat Gain

GL — Wed, 07 Aug 2019 14:27:44 GMT

On Design Database I have specified body sensible and latent heat gain as below; however on room data sheet causal gain only picks up casual w/m^2 which is 0. Can you confirm if the heat gain from occupied body is taken into account as specified below.

K VALUE FOR DEFAULT BENDS AND TEES

GL — Tue, 16 Apr 2019 09:34:31 GMT

Understood the below links gives K-value for some of the fitting however, it doesn't show the assumed value for different default bends and tees . Please could you be able to post the k vale for the default connection fittings. i want to verify the pressure loss is correct and is inline with CIBSE guide C.

CWS PD/METER

GL — Mon, 29 Apr 2019 14:13:43 GMT

IS IT POSSIBLE TO DEFINE CWS SYSTEM WITH MAX 250PD/METER. UNDERSTOOD THERE IS A WAY TO DEFINE MAX VELOCITY, HOWEVER AS THE VELOCITY AND PIPE INCRIMINATE IS NON-LINEAR THE SOFTWARE UNDER SIZES THE PIPE RESULTING IN HIGH PD PER METER. PLEASE ADVICE IF THERE IS ALTERNATIVE WAY TO LIMIT PD/METER TO 250PA.

CWS PRESSURE DROP PER METER

GL — Thu, 25 Apr 2019 13:52:40 GMT

I ASSUME LIKE IN DUCTWORK THE PRESSURE DROP PER METER INCLUDES MINOR LOSS IE FITTINGS. IN CWS PRESSURE DROP PER METER NOTE. IS THERE A WAY WITHIN THE SYSTEM TO EXCLUDE THE PRESSURE DROP DUE TO FITTINGS.

Netsys Duct at different height on same floor connection.

GL — Thu, 04 Apr 2019 08:30:56 GMT

This is my first project in Netsys Ductwork Please could you be able to answer below questions

1) If you have two ducts at same height level and inter-crosses how do you design bends to avoid collision?

2) How do you model branching duct at different height level from the main duct line?

3) What does this fitting do Depression down, depression up, offset down & offset up?

4) Connecting duct and diffuser to plenum box, it does not appear as connected. Appears as only duct and diffuser are connected. Is there a particular method for connecting all three?

Many Thanks
