I mated a Prestcold Condensing Unit
Model Number PR500/A0089-12-BS
to a 20 kw evaporator, and wrongly specified a size 6 orifice for the Danfoss ext equalised expansion valve.
The valve is overfeeding...............sending liquid all the way down the suction line, all 10 metres of it.
I have turned the valve in and to try and reduce flow through the valve, but not having much effect, now Ive got a clump of ice around the valve body itself.
I need to replace the size 6 orifice with the correct one. Would anyone be able to help tell me the size of orifice I need.
I dont have a data sheet on the capacity of this condensing unit. All I can say is I am using it for a freezer application and using refrigerant R22.
