Basic maths

[Rob White]

.

I need someone to do a basic maths equation.

I am doing some revision and homework, a training
slide I have read gives an example for refrigerant charges.

......................................................

An example of the comfort cooling / heating equation or a room
cooled by an R1234ze split air conditioning system with a ceiling
mounted indoor unit is shown below:
• LFLR1234ze = 0.303 kg/m3
• h = 2.2 for ceiling mounted unit
• A = 9 m x 5.5 m = 49.5 m2
M = 2.5 x 0.3031.25 x 2.2 x √49.5

M = ??? kg.

......................................................

I know what the answer is, I have worked out the answer but it
differs from their answer and because they are doing the training
I am starting to doubt myself?????????????

So please do the simple equation above and post the answer.

No prizes, I just want conformation about my answer.........

Regards

Rob

Bit difficult Rob, as your M= line contains some funny number (0.3031.25) which I assume should be 0.303 x 1.25??

Thank you Frank.

You confirmed it for me, I'm not loosing it, just yet

I was doing a training slide from Real Alternatives sponsored by the IOR and
that was their equation.

Phew.............. I'm not mad

Cheers Frank treat your self to half of what you fancy and bill the IOR
