Is it true that with your estimate of 2 to 2.5 ton heat pump, that is based on the cooling load. Which is smaller than the heating load (about 3.5 tons)?
From my understanding of 2 stage unit, it runs under 2 different loads. So if the temperature is not very hot, it would run at smaller setting. Assuming that the smaller setting matches the cooling load, then it would run long enough to remove the moister.
However, if I base the system on the heating load, for example, and the lower setting stage is still too large for the cooling load, then short cycle will happen, and all sort of issues occur.
Ideally, based on the equipment datasheet, a correct equipment must have at 1 of their stages to meet the manual J's calculation.
I found an example datasheet here:
Would someone please tell me what would be a good match for me from this data sheet?
I can see this:
Outdoor unit RPRL would be: 036JEC
ID Coil: RCFM-H*3617A*
ID Air Mower: RGFD-06?MCK?
It's a bit low for the winter. Maybe something a little bigger.
Also, assuming that the control is good enough to automatically do this so the users don't have to set the stage manually.
Since my problem is not new, and I don't see anything unique about it (just calculate heat gain/loss, and find a heat pump unit for it), would the pros who work on this often please tell me if it's easy to get a system to satisfy my need?
