R22

Can somebody tell me if R22 is banned or going to be banned

A customer has six R22 split systems that are in quite a bad state. I could possibly repair them but I wanted to know if R22 is still widely avaliable

R22 is still available and usable however it will have a limited lifespan.

Would suggest replacement if the kit is past it.

R22 will be hard and expensive to obtain after about 2008.

Thanks for that.

My Customer has some very strange shaped rooms, can you recommend any programmes for caluclating the correct size system ?

You'll probably have to break the rooms up into regular shapes, squares, triangles etc., to calculate the areas and volumes.

.

Odd-shaped rooms provide odd problems, so don't foget to consider the odd-shaped air distibution.

The design is only as good as the conditioned air reaching as complete a path throughout the room and back again to the AHU as it can.
