Most the Advantages of Mini's, but with Maxi-Splits

What is your point here????? I see none!!!!

Why not find a trade website to preach to.

Nothing you've said here, or in your other rants, makes much sense.

I was confused by his posts also. But relative to this one, here in Iowa, the school systems do not waist money with AC, as they don't occupy the buildings in the summer. There were a few hot days during Sept., and they let the students out in the afternoon. And for heating in the winter, heat pumps have such a short season where the outdoor temperature is above 32F as below this the COP drops off quickly below unity. I'm believing that Ohio has these same conditions of school usage, and climate conditions, as a good part of the state gets lake effect snow. And the whole state has a winter with snow, and I know this is below 32F to occur.

I found a snow map of Ohio: sorry the resolution is so pixelated.

So it would not make sense to have a AC/heat pump system of any kind in our climates. Looks like their school board is doing its job.

I will not abrv so much:

just a phrase from mini-splaits, that a maxi split would on a larger scale.

Larger such as split consoles and corner standing units in class rooms which also either were connected to water-to-water reverse cycle chillers for heat in some common designs; but also having series flow refrigeration specification for ON-Demand Hot water heat recovering means from a same vertical or RTU Heat Pump while cooling has full HW condensing (condenser fan or pump off-line then) which mini's don't offer nor as instant hot water heating which other larger school system heat-pumps can do with the heat of the systems producing for Hot Water by temperature control and 100% on demand.

Hmm.

Well I tried in other posts to help you understand such as rejecting heat to the ground is not a "over-unity" thing so seemingly well rehearsed to see in many posts...

here:

Someday [Hopefully] maybe Ohio and other states will have engineered more "equal" specifications for bids as so many southern schools benefit from: For instance, it took a senator's stamp of disapproval for the closed engineering to release rights of the school systems in AR to get quotes on well qualified but "not in the engineering circles" equipment.

Since OH ignored the OSFC "must comply with energy star" for previous mandated "must have 3rd party rating" much has been lost in better GeoThermal and probably air Source heat pumps not being ALLOWED to bid against less efficient and less qualified but approved 3rd party rated OEM systems. Simply expounding it must be 3rd party rated did not make it any more reasonable for what had to occur anyway. When the 3rd party rated units don't meet in the field the purported rated rating, they get pulled and replaced by OEM total expense, without prejudice.

2)

Heat Recovery and the oversized heat exchangers already of some OEM's have put heat pump schools at over 30% better off HVAC-RFG-Hot-Water mechanically than the 2008 "goals" of then ASHRAE NY wanted to discuss.

BUT THE POINT DEAR LYN?

There has been for some time needed far more than just some "must have 3rd party rating" and that by the FOR PROFIT ratings companies.

If a statement and backed by OEM's anyways always the same: gotta remove 'em if not COMPLIANT-- is the same for "3rd party rated" as it is for "We are compliant with Energy Star(tm) (minimums, say 2013 and coming 2014)

WHY NOT HAVE ???? : More general for bidding specifications that allow for 'split' advanced heat pump systems of multi-staging variable compressor drive designs. Spec's to have "optional heat recovery to 100% hot water production"... (full condensing, not just little desuperheating generation of hot water) .

WHY NOT make for better quotes and better quotes with heat recovery available in states like Ohio, by COMPLIANCE rulings in bidding?

IT is not just HVAC, but HVAC-HotWater-Rfg - heat reclaiming in schools that the FIRST net zero school system, and one of 3+ years now, also used the least amount of a solar compliment compared to another { first net zero school of 2 mil solar: vs: 7 mil, other similar structure different HVAC, similar population }

3)

Air source heat pumps too? The gas dollars to maintenance and total controller accountability seems to point to shutting off at 27 to 28 ,, and it is that 37f is where the graph begins a fall , but stabilizes over to 17f with standard higher efficiencies in N Ohio climates.

All on the table LYN. It ids still to date very needed.
