What sort of Technician are you ?

I understand that English is not your native language but your questions are most confusing.

What is 60 Watts as the cubic metre ? This has no meaning whatsoever.

Watts = power
Cubic metre = volume

How big is the cubic, is it a metre ? A cube is a shape and the sides can be measured in any dimensional unit that you wish; mm, cm, m, inches, feet, thumb prints, arm lengths etc.

Brain, this goes back to another thread where someone suggested the energy density to design cold storage rooms.

Ray Ang SM,
As a side note, I would like to emphasize this sort of design procedure should NOT be used. It does not take into account aspects of a heat load that can greatly vary from location to location or application to application.

Just because it looks easy, does not mean it should be used for all, or any application. This is a good way to get yourself into expensive trouble.

are you calculating heat load you have in order get size of the A/Cunit if it the case you you mean100W per sq/meter

When ever someone post question about heat load, always pop up someone enthusiastic with these ridiculous rules of thumbs. :mad:
How on earth you know about what building type and construction we deal here when there is no 1 word about that.:eek:
Suppers your euphoria, and keep these rules for yourself, if you don't know about what you are talking.
Educate yourself about heat load calculations, then (and only then) you could apply some rules of thumb in certain well known situations but not in situation like this where there is no one word about conditions and building.

Start with insight what it is about here (http://personal.cityu.edu.hk/%7Ebsapplec/cooling.htm)

Astra, he's from Singapore, your rules of thumb certainly don't apply over there (humidity is very high, temperature is higher then in the UK, construction of buildings,...)
