Copper coil heat exchangers. These heat exchangers are immersed in a heat
storage tank. Similar to what can be constructed at home.

provides some design guides...
While the temperatures they give in the tables are different than would
normally be used in solar applications, they do provide some adjustment
factors for other temperatures.
The tables are done for Twater in = 180F, Tair in = 60F. It appears to
be pretty close to adjust the table heat transfer by (Tw - Ta)/120F, where
Tw is your water in temp and Ta is your air in temp. This can be
used to get a rough idea for values not covered in the correction table. |
