Actron Air / Airflow Issues on a 71kW Tri-Capacity Package Unit

A bit of history with this site. Originally had an old Bradway unit. Repaired it multiple time. Eventually they decided to replace it. Had another company install this Actron Air packaged unit. When I went back for a maintenance after the replacement the CP05 co triller had multiple HP and discharge temperature alarms. Found the static pressure was around 490Pa. The airflow was severely restricted. Suggested they get the installers back to rectify this but they had apparently gone out of business. This video starts after our Mech department had carried out duct rectifications.

You must have someone where they big paycheck when you run a 71KW strip that’s a lot of amps I couldn’t afford to pay the bill one time alone all through the winter but I think it’s the biggest KWI I’ve ever heard of so I hope someone stays warm during the winter From Tallahassee, Fred

That 71KW is probably delivered capacity. So with a COP of 5 it should draw 14,2kW from the grid. And Australian winter temps aren't too drastic so it probably is still doing a COP of 3 on the colder days in heating.

The above explanation is spot on 👌

It is so nice to see neat electrical panel for a change. Don't know why but the US manufacturers cannot produced a clean electrical panel, wires hanging everywhere, not using good quality switchgear. Them PVC cable management trays are not that expensive. Saw one video where they are using 2 pole contactor for a 3 phase load and keep 1 phase connected at all time.

Most of the units I come across have a similar setup for the wires. It’s a lot nicer until someone starts yanking out wires and not putting them back. Turns in to a shit show very quickly 😂

Hey AC man that’s a lot of metal sheet metal or the ductwork. I seen some big equipment before with a lot more compressions than three. I’ve seen them with four and five compressors and one unit but I don’t think I’ve ever seen one with that much for the heat 71 KW.

Hey mate what app are you using for pressures and temps? And what testo fittings ?

@hvacraustralia Месяц назад

It’s MeasureQuick. It’s a good app to display all the readings. I usually swap between the testo app and MQ. My Testo Probes are the 115i clamps, 549i pressure probes and the 605i air probes.

@@hvacraustralia thankyou can the probe also act as a vacuum stat

@hvacraustralia Месяц назад

No unfortunately. That’s a seperate probe. 552i
