* Performance results are for the Solar Rating and Certification Corporation (SRCC) rating day and are derived from TRNSYS simulation in conjunction with SRCC OG-200 system test results. OG-200 tests were independently conducted by DSET Laboratries, Inc. Phoenix, AZ.
The solar water heating system
shall be of the integral collector storage (ICS) type, and shall require no
pumps, controls, or parasitic energy consumption for its normal operation. The
ICS unit shall be the SunEarth CopperHeart ICS model number _____________. The
CopperHeart ICS unit shall be tested in conformance with SRCC Standard OG-200 by
an independent testing laboratory, certified by the SRCC under system standard
OG-300, and also by the Florida Solar Energy Center (FSEC).
The dimensions of the CopperHeart
ICS model number ________________shall be________inches in length, 36 ½ inches
in width, and 6 7/8 inches total depth to the top of the glazing capstrip, and
be rated at a nominal capacity of __________________U.S. gallons. The casing
shall be an anodized aluminum extrusion (alloy 6063 T5), a minimum 1/8 inch in
thickness, with an architectural dark bronze finish. Sheet metal fasteners shall
be stainless steel (18-8 #10 X ½). The framewall shall be secured by four
exterior anodized aluminum corner brackets attached with 8 each AD54BS aluminum
rivets per corner. The casing backsheet shall be painted textured aluminum of
not less than .014 inches in thickness.
The glazing shall be one sheet of
low iron tempered glass of not less than 1/8” inch thickness, and have a
minimum transmissivity of 91%. The glazing shall be thermally isolated from the
casing by a continuous EPDM gasket. There shall be a secondary silicone seal
between the glass and the aluminum capstrip to minimize the intrusion of
moisture into the casing.
The backing insulation shall be a
foil-faced polyisocyanurate foam sheathing board with a minimum thickness of 1
½ inches, and shall be siliconed in place to the aluminum backsheet. Aged
thermal resistance R-value of the backing and side-wall insulation shall be not
less than R-12 at 75 F mean temperature. The ends of the ICS shall be insulated
with 1inch polyisocyanurate foam sheathing board with an aged thermal resistance
R-Value of no less than 7.2.
The CopperHeart ICS shall combine
the collector and storage tank as one unit. The all copper storage cylinders
shall be seamless drawn 4.125 inch O.D. copper tubing with a minimum wall
thickness of .058 inches, and have machine spun ends to accept 7/8 inch O.D.
Type L copper internal manifolds. Eight storage cylinders shall be manifolded in
series to form a storage vessel. The rated internal working pressure shall be
120 PSIG at 200 degrees F. All
internal manifold braze joints shall be joined utilizing a copper phosphorous
brazing alloy with no less than 15% silver content and conforming to the
American Welding Society’s BCuP-5 classification.
EPDM grommets shall isolate the manifolds from the aluminum casing.
The absorber coating shall be a
moderately selective paint with a minimum absorptivity of 94 percent and a
maximum emissivity of 56 percent.
