May I ask to remove all your double posts please?
It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Re: which unit do i need??
Well Davej, you posted the same question in different sections and the chance that someone answers then you question is nil.
We take mostly an average load of 100 to 125 W/m².(32 to 40 BTU/ft².h), air change min 4 to 5 times the space volume.
If the units needs also to heat the building, then a well isolated building needs +/- 50 W/m³ (171 BTU/h/35 ft³)
Hope I didn't converted the wrong way.
What are SI units so much more comfortable
In fact, I even didn't understand the 10'6
10' is for us 10 minutes.It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

When posting a question, it is better to chose the appropriate section for your question.
Some new posters choose the wrong section or think that it is a good idea to 'multiple' post in all the sections.
For long serving members, this can be annoying, seeing the same post over and over again.
What Peter was asking was for the 'multiple' posts to be deleted as they do not serve any extra function other than to annoy members.
Careful, polite and respecful posts normally generate the most response.
Also, new posters should remember that we all have daytime jobs so answers may take some time and are not always immediate.

Re: which unit do i need??
AH RIGHT PETER, Sorry. 10'6 should have read 10foot 6 inches by ten foot 6 inches- inside measurements of conservatory. so could you go further with your calculations and try to give me a rating for unit needed PLEASE ;-)

Without this precise information we can only advise on a 'Rule of Thumb' calculation. Peter has proposed 125w/m2 whereas I would increase this to 200w/m2 to be confident of matching south facing, PVc construction conservatory heat gains. So for a floor area of 3.2 x 3.2m (10.24m2) x 200w/m2 you would need 2.048kw of cooling.
Please remember that this is only a guide and a full calculation should be carried out before selecting suitable equipment.
