Is 134 Degrees F normal from a Gree Crown?

Xringer · 10-27-16, 09:21 AM

It's a nice cool morning and I checked the output vent..
134F is a lot higher than my Sanyo is putting out this morning..
(My Sanyos never get that warm)..
Is this a normal peak temperature for a Gree?

It is keeping the house pretty warm.. Set at 70F..

Thanks,
Rich

It sounds like yours is a little more efficient than my terra series. I get about 125F but that still feel good.
I am glad you are posting the how your new mini split was doing. I was wondering how it was performing.

What is your outside temp?

Wouldn't it be more efficient to have a lower outlet temp?

We have not been using it a lot. It just started getting cold a few days ago.
Seems like it uses a lot of power when running, but it shuts down to under 10 watts
after it exceeds the setpoint, by 2 or 3 degrees..

It got down below freezing for a while this morning..

It seems to be using about the same power over-all as the old Sanyo..
Both the Sanyo (Den) and Gree (LR) used 6 kWh each since midnight.
About 14 hours for $2.50. I think the power cost is going to remain the same.
But, it be higher at times, since I'll be able to run the Gree during extreme cold.
(When the Sanyo will be off, with the space heaters in the Den)..

The Sanyo does not run at 890 watts for a while and shut down..
It just keeps running at 480 watts much longer before dropping down to idle.
The Sanyo keeps the room temp more stable.. Less under or over shooting of the setpoint.
I had to turn up the 10A current sensor on the LR power drop..
This Gree will slowly move up to 2.8 KW and run there for a while.
I think it's sucking down 12 to 13 amps on peaks..
To my horror, we had a voltage peak this morning of 247 VAC!!
That can't be good for the power supply...

Rich,

I don't worry about a 247 V or even 250 V. The insulation on the wires and the electronics are well within limits. What concerns me are under voltages such as 210 and 205. That results in higher current, higher heat and potential melting of insulation.

The local utility has me set for 248 volts coming in from the automatic switching transformers. They can select voltages and they start high so that any peak demand results in a "sag" that is well within limits.

Regarding the 135 F temp from the new minisplit - is the the same air flow as the old unit?

Thanks Steve. The voltage goes back down after the morning peak.
Nope, it's 247.2Vac right now at 15:07 eastern..

The air flow is high whenever the Gree is running hot. But, it does go to zero power
pretty quick when it hits it's target setpoint. So, it's sitting there at over 100F w/o air flow.

The airflow on the Sanyo (also set to auto) is less, but it's hard to tell,
because the IDU fan is a little wider than the Gree..
The Sanyo will run at higher air flows (fan motor RPMs) only during the early part of the power startup cycle..
Right now, it's at 90F in the vent with low to medium air flow..

The Gree has a new power-up surge cycle going on, each time it wakes up
and notices the low temp limit has been hit..
The duration of the cycle depends on load (are the bedroom doors open etc).

Xringer, on one of the posts on your new Gree Crown you mentioned something about it being a crown and not a u-crown. what is the difference between the two?

I am looking for a small heat pump for the studio. and thought the crown looked good (-20F!). the u-crown. available in canada. Is significantly more expensive here. so if the two units are identical. and by the specs they do so appear. then I would order from the US.

There was a U-Crown discussion at http://ecorenovator.org/forum/geothe...install-2.html

Starting at post #17. If you are going to compare U model to the USA model,
I would start off looking at the case size and weight etc.. Then the SEER & COP info..
That comment about the compressors might be a clue to the difference.?.

Glad to hear the new MS is working OK . :-)

To compare the 2 , cost of electricity wise , I would think you would hace to compare the cubic foot of the spaces they serve ? And assuming both spaces had the same rate of heat loss .

I have been running our 16 SEER bedroom Friedrich unit on heat for the lasr few nights . Has not gotten cool enough to run the living room MS on heat , to any significant extent .

It has been rainy last few days . Current temp at 01:15 is 59 F . More rain predicted for a day or 2 .

Have not fired up the central furnace .

I have a blue flame heater in the converted garage / computer room . Lit it a couple of times .

God bless
