Hiya guys, long time reader but first time poster so be gentle with me.
I'm an electrician/AC fitter. We do do refrigeration (chilled water AC) but at the moment it's just split install's.
I've been in the trade just coming up 3 years so still got plenty to learn especially on the fridge side of things.
And thats where you guys come in.
As a little bit of a project, i'm using some surplus gear from work that was going in the skip to build a heat pump/AC for a club house. It's mainly for winter heating but thought i might aswell do both.
To keep things simple (read: cheap) i was thinking of using capillary expansion, only problem is, the rig is looking to be about 22Kw. All the simple calc software etc says capillary is only really used upto a max of about 10kw, and i dont know enough about this stuff to know why?
I'm not looking for close control or anything, just a warm breeze in the winter and a cold breeze in the summer.
Do you reckon i'd be able to obtain this with caps?
Can anyone post the calculation formula, or a software calc that goes higher than the danfoss 10kw limit?
Look forward to your responses.
Cheers Guys,
Chris
PS: basic system spec - 22.5Kw, R407c, Cond 45DegsC Evap 10Degsc
