These are some working results from a few tests aimed at refining the DWH pond into a workable configuration. Any ideas would be appreciated.
Floating Lid - Sprinkler 050709
Floating Lid Flow Test 05/07/09
Floating Lid Flow Test 05/07/10
Floating Lid Flow Tests 05/07/12 and 13
Hourly sim run Billings, Jan, 30sqft collector, North reflector, 6 inch depth
Hourly sim run Billings, Jan, 30sqft collector, North reflector, 12 inch depth
Hourly sim run Billings, July, 30sqft collector, North reflector, 6 inch depth
Hourly sim run Billings, July, 30sqft collector, North reflector, 12 inch depth
Hourly sim run Billings, Jan, 60sqft collector, No reflector, 6 inch depth
The definitions of the data in each column are:
Mo Month eg Jan = 1
Day Day of month
Hour Hour of day
Tamb Ambient temp F
Itot Total solar radiation (direct + diffuse) from TMY
IDHWtot Total radiation on surface of collector
I45DHWtot Total radiation if collector were titled at 45 deg
QGain Collector gain for hour BTU
QLoss Collector loss for hour BTU
QNet QGain - QLoss
Qdraw Heat removed by a hot water draw (BTU) (20% of 30 gal at 8am, 80% at 4pm)
Tstor Storage temperature at end of hour (including effect of a draw if any)
The unlabeled numbers in last column are the fraction of hot water provided by solar pond.
