Hi guys
I got called out to a Comms Room with 2 of these Ipac IP 30 Dx downflow units installed. The job is approx 2 years old and the customer tells me there been an ongoing issue with them since day one including refrigerant leaks.
The room temp is a little higher than usual one side so i checked the unit over.
The system operates on R407c.
I am getting:-
Air on to indoor @ 24c
Air off indoor @ 16c at best 15.8c
Suction pressure fluctuating between 5 and 6 bar
superheat taken from evap outlet between 8 and 11k
No temp drop across filter drier
Air on to outdoor coil was 12c
Air off 37c
High side at Remote condenser inlet fluctuating between 18 and 19 bar by speed controller.
sub cooling taken at remote cond outlet between 9 and 11k
Sight glass clear but flashes intermittently.
Any help would be appreciated.
Thanks
