Hello everyone

I need to replace a R22 system manufactured by RA of Haverhill England.
It seems the company no longer exists.

The indoor unit is a VAH50 PE in a computer room
and the outdoor system which is a ducted type of unit is a Delta 5CU 050.

Does anyone know the cooling capacity of this old R22 system?

regards pingo

Try checking the duty of the expansion valve.

Compressor data would be better

You could contact Heronhill, http://www.heronhill.co.uk/
they may have some of the original reference literature for this unit.

Thanks to hyperion ,multi and Brian for the replies to my question,

I will try heronhill to see if they have anything in there archives.
also when i am back on site i will get access to the compressor to see the model rating.

I guess from the condensing unit model number it will be a 5ton cooling system.

thanks pingo

The 050 may allude to 50k btu?
