MONTHLY PERFORMANCE REPORT
SOUTH DAKOTA SCHOOL OF MINES
JUNE 1979

I. SYSTEM DESCRIPTION

The South Dakota School of Mines solar energy system is installed in the
visitors' center of the Mount Rushmore National Memorial at Keystone,
South Dakota. The solar energy system is a retrofit to the original heat-
ing and cooling system, and is designed to provide 45 percent of the annual
heating requirements for the entire building and provide 53 percent of the
annual air conditioning requirements for the observation room.

Solar energy collection is performed by 112 double-glazed, flat-plate col-
lectors manufactured by Lennox Industries, Inc., that have a gross area of
2,000 square feet. The collectors are mounted in six arrays on the roof
of the building, and face 19 degrees west of south with a tilt of 46 degrees
from the horizontal. The main system loop contains 150 gallons of 50 per-
cent ethylene glycol and water solution, which is used to transfer energy,
as required, from the collector to the collector-to-storage heat exchanger,
the collector-to-space heating heat exchanger, and absorption chillers.
Thermal storage is provided by 3,000 gallons of water in a steel storage
tank that is insulated with three inches of fiberglass.

Heating demands are met by transferring energy from the collector, or stor-
age, to heating coils in the building multizone air handler. The multizone
fan is energized continuously to circulate building air, and dampers in the
multizone unit are positioned to allow flow across the solar heating coil
when the system is in a solar heating mode. Auxiliary heating is provided
by a two-stage fuel oil furnace.

Thermal energy from the collectors is used to operate three absorption
chillers; chilled water from these chillers is circulated through a cooling
coil in the observation room air handler. Thermal energy from storage is


1 4294









not used to operate the chillers because of temperature limitations. Auxil-
iary cooling is provided to both the multizone and single-zone air handlers
by vapor compression units.

This system, which is shown schematically in Figure 1, has six modes of
solar operation.

Mode 1 Solar Energy Collection: The solar collection mode is entered
when the collector absorber plate temperature is greater than 100*F. In
this mode, pump P1 is energized and valve V4 is positioned to allow flow
through the collectors. This mode is entered even though there is no
heating or cooling load and storage tank charging criteria have not been
met. This mode continues until the collector plate temperature is less
than 1000F; however, an adjustable time-delay circuit delays pump P1
shutdown to prevent short cycling.

Mode 2 First Stage Heating From Collectors: This mode is entered when
the system is in the collection mode and a demand for heat is determined
by the difference between the conditioned space thermostat setting and the
discharge air temperature in the multizone air handler. In this mode,
valve V7 is positioned to allow flow through the heating coil HX2 located
in the multizone air handler, and valve V5 is positioned to bypass the
absorption chillers. Flow through the heating coil is provided by pump Pl.
If the heating demand cannot be met using solar energy, a fuel-oil furnace
is used in conjunction with, and independent of, solar heating.

Mode 3 First Stage Heating From Storage: This mode is entered when there
is a heating demand, energy is not available from the collectors, and energy
is available from storage because the top tank temperature is greater than
1000F. In this mode, valves V5 and V7 are in the heating positions, and
valve V4 is in the collection bypass position. Valves Vl and V2.are posi-
tioned to allow flow into the bottom and out of the top of the storage tank.
Pump P2 is energized to circulate water between the storage tank and the
water side of the storage heat exchanger HX1, and pump P1 is energized to

circulate the main system fluid between the glycol/water side of exchanger
HX1 and the liquid side of heating coil HX2 in the air handler. Multizone
air handler and oil furnace operations are the same as described in Mode 2.

Mode 4 Single-Zone Cooling From Collectors: This mode is entered when
sufficient solar energy from the collectors is available, and when a de-
mand for single-zone cooling is determined by the conditioned space thermo-
stat (located in the observation room) and the discharge air temperature of
single-zone air handler.

Since generator inlet temperatures of 1800F are required in order to operate
the ARKLA absorption chillers, this mode is not allowed until collector out-
let temperatures reach this level. If temperature requirements are met,
valve V5 is positioned to allow flow through the chillers' generators, pro-
vided that pump P3 is operating to circulate chilled water through the solar
cooling coils. Pump P4 is energized to circulate condensing water through
the cooling tower. The cooling tower fan is controlled by an aquastat to
maintain a sump temperature of 850F.

Safety cutoffs are also provided to prevent either overheating or excessive
cooling of the chillers. No solar cooling from the storage mode is provided
since maximum storage tank temperature and energy losses prohibit efficient
operation of the chillers. Auxiliary cooling will be provided by vapor com-
pression units (A/C unit) in the single-zone and multizone air handlers.

Mode 5 Storage Tank Charging: This mode is entered when the inlet
temperature on the glycol/water side of the storage heat exchanger is
200F greater than the storage tank bottom temperature. This mode is also
entered in the cooling mode if, in addition to being 20F greater than
the storage temperature, the heat exchanger inlet temperature (glycol/
water side) is greater than 1950F.

In this mode, valves Vl and V2 are positioned to allow flow into the top and
out of the bottom of storage, and pump P2 is energized to circulate water
from storage through the heat exchanger. This mode is stopped if storage
tank temperatures exceed 2050F.


4 4294









Mode 6 Excess Heat Rejection: This mode is entered when the storage heat
exchanger outlet temperature (T103) exceeds 2050F. In this mode, valve V3
is positioned to allow flow through the heat rejection cooling tower. The
fan in this tower is controlled by an aquastat to maintain a sump temperature
of 195F.

II. PERFORMANCE EVALUATION

The system performance evaluations discussed in this section are based
primarily on the analysis of the data presented in the attached computer-
generated monthly report. This attached report consists of daily site
thermal and energy values for each subsystem, plus environmental data.
The performance factors discussed in this report are based upon the defi-
nitions contained in NBSIR 76-1137, Thermal Data Requirements and Per-
formance Evaluation Procedures for the National Solar Heating and Cooling
Demonstration Program.

A. Introduction

The Mount Rushmore Visitor's Center solar energy system was operational
throughout the month of June. However, due to the failure of a signal
conditioning module in the SDAS and resultant measurement errors on the
first 32 channels, data for the first 15 days was not useable for report-
ing purposes. This report, therefore, covers only the period from June 15
through June 30, 1979 for which valid data was received. Consequently,
the accuracy of the estimated monthly energy values may be significantly
less than normal.

During this reporting period, the first cooling operation by the solar energy
system for 1979 was observed.

B. Weather

During the last half of June, the measured outside ambient temperature was
62*F which is 20F below the long-term average for the Rapid City, South
Dakota area. The measured average insolation in the plane of the collector


5 4294








was 1,293 Btu/ft2-day, 28 percent below the long-term average of 1,802
Btu/ft2-day. Long-term environmental data are derived from data supplied
by Reference Monthly Environmental Data for Systems in the National Solar
Data Network, Department of Energy Report, SOLAR/0019-79/36.

C. System Thermal Performance

Collector During the reporting period, a total of 41.37 million Btu of
solar energy was measured in the plane of the collector array. The sys-
tem collected 9.43 million Btu or 23 percent of the total available
insolation. During the time the system was operating, a total of 28.61
million Btu was incident on the array. This represents an operational
collector efficiency of 33 percent. A total of 0.40 million Btu of
electrical energy was required to collect solar energy when the system
was operating in the collection or storage modes.

Storage Storage calculations show that 3.53 million Btu were delivered
to storage during the reporting period and 2.68 million Btu were supplied
from storage. Storage losses included 0.72 million Btu from the storage
tank and an additional 0.77 million Btu from the collector loop-to-storage
loop heat exchanger. A total of 1.34 million Btu was delivered to storage
during periods when the storage loop pump P2 was off, apparently due to
thermosiphon flow in the storage loop. A net decrease in stored energy of
0.13 million Btu was observed during the reporting period. Excluding the
stored energy input due to thermosiphoning, the storage efficiency was 72
percent for the reporting period.

Space Heating Load The space heating load for the reporting period was
1.65 million Btu. Solar energy supplied 1.44 million Btu of this load,
which represents a heating solar fraction of 87 percent. An average
building temperature of 71F was maintained during the reporting period.
There was no first stage heating from the collectors for this period and
the entire solar contribution to the heating load was supplied from storage.
Operating energy required to deliver solar energy to the heating load
amounted to 0.10 million Btu. A total of 0.97 million Btu of solar energy
was intentionally rejected by the heat rejection cooling tower.


6 4294










Space Cooling Load The space cooling load for the reporting period was
8.16 million Btu. Solar energy supplied 1.13 million Btu of this load,
which represents a cooling solar fraction of 14 percent. Solar energy
input to the absorption chillers amounted to 3.84 million Btu, resulting
in a coefficient of performance (COP) for the solar cooling subsystem of
0.29. Auxiliary cooling provided by the vapor compression air conditioners
amounted to 7.02 million Btu from the unit in the multizone air handler
and 0.011 million Btu from the unit serving the observation room. Operating
energy required to deliver solar energy to the cooling load amounted to 0.31
million Btu.

D. Observations

Review of scan level data for June 30 showed near freezing temperatures
(measurements T502 and T552) at the inlet and outlet of the solar cooling
coil which receives chilled water from the solar fired absorption chillers.
With concern that these low temperatures could result in freezing and
potential damage to the chillers, the Project Manager was notified who in
turn notified site personnel. Data further showed a cessation of air flow
through the observation room air handler where the solar cooling coil is
located. Investigation by site personnel revealed a broken fan belt on
the air handler fan. The fan belt was replaced and normal operation was
restored on July 3, 1979, with no apparent damage to the system.

E. Energy Savings

The solar energy system at Mount Rushmore provided a savings of 2.39 million
Btu of fossil fuel during the reporting period and a savings of 0.32 million
Btu of electrical energy. This savings was realized at the cost of 0.40
million Btu of electrical operating energy for the Energy Collection and
Storage Subsystem (ECSS).


7 4294









III. ACTION STATUS


Sensor T400, which was cited as being in error in the monthly performance
report for May, was replaced and recalibrated in early June and is now
consistent with other temperature sensors in the collector loop.


Discrete signal D002 which indicates the status of valve V5 (through or
bypass ARKLA units) appears to be non-functional. This problem will be
corrected during a site visit scheduled for July 1979.
