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????????????? :o :confused:

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

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

Regards

Rob
