MONTHLY PERFORMANCE REPORT


HELIO-THERMICS, INC.
HOUSE LOT 6

JANUARY 1979

I. SYSTEM DESCRIPTION

The Helio-Thermics Inc., House Lot 6 is one of two instrumented single-family
residences in Greenville, South Carolina. The home has approximately 1086
square feet of conditioned space. Solar energy is used for space heating the
home and preheating domestic hot water (DHW). The solar energy system utilizes
the attic space as the solar energy collector. The attic roof faces 10 de-rees
west of south and is pitched at an angle of 51 degrees from the horizontal.
Solar energy enters the attic through a 416-square-foot aperture which is
double-glazed with corrugated, translucent, fiberglass-reinforced, acrylic
panels. The interior of the attic is painted black to maximize the absorption
of solar energy. Warm air accumulates in the peak of the attic roof and
circulates through the conditioned space or through storage by an air handler.
Solar energy is stored in an 870-cubic-foot storage bin containing 85,460
pounds of crushed rock. The bin is located under the house and is insulated
with 2-inch polystyrene insulation. Cold water is preheated in the attic by
thermosiphoning water from the 80-gallon preheat tank through a manifold
system of copper tubes. These tubes are attached to black sheet-metal plates,
thus enhancing absorption of solar radiation for preheating the water as it
circulates to and from the preheat tank. Preheated city water is stored in
the preheat tank and supplied, on demand, to a conventional 80-gallon DHW
tank. When solar energy is insufficient to satisfy the space heating load, a
water-to-air heat exchanger in the hot air supply-duct provides auxiliary
energy for space heating. A gas-fired water heater provides auxiliary energy
for the water-to-air heat exchanger and DHW. The system, shown schematically
in Figure 1, has seven modes of operation.

Mode 1 Collector-to-Storage: This mode activates when there is no deiiiind
for space heating and the collector supply-duct temperature is 26'F higher
than the storage temperature. This mode terminates when the temperature
difference between the collector and storage is less than 160F.

Mode 2 Storage-to-Space Heating: This mode activates when space heating is
required (but is not available from the collector) and the storage temnpera-
ture exceeds the building ambient temperature by 5F. This mode terminates
when the building ambient temperature equals the storage temperature or when
space heating is no longer required.

Mode 3 Collector-to-Space Heating: This mode activates when space heatintl
is required and the collector supply-duct air teCmperature is 10 F hiliher than
the building ambient air temperature. This mode termlinittes when the tempera-
ture difference drops to less than 6"F or the space heatirng requirem-' ent is
satisfied.

Mode 4 _- Auxiliary EnerHy-to-Spdace Floating: This m1ode1 a( tivatps when space
heating is required and thermal energy is not available tfromn the collectors
or storage. An electrical heating element in the hot air supply-duct -reriins
on until the space heating demand is satisfied.

Mode 5 Summer Mode, Passive Cooling Storage: This mode can be activated
when the residents wish to store cool air in storage for circulation the next
day. The air-handler fan activates and an outside air-intake damper opens to
allow the cool air to circulate through the attic and storage.

Mode 6 Summer Mode, Space Cooling: This mode can be activated when cool
air from storage is desired in the living area. The outside air-intake
damper closes, the duct to the living area opens, and the air-handler fan
activates.

Mode 7 DHW Preheating: This mode activates when there is a demand for hot
water. Water is drawn from the conventional DHW tank and replenished with
heated water from the preheat tank. The DHW subsystem has this one independent
mode of operation for preheating.


II. PERFORMANCE EVALUATION

INTRODUCTION

The site was occupied in January and the solar energy system operated con-
tinuously during the month. The solar energy system provided a fossil fuel
energy savings of 1.7 million Btu.

Several one-time anomalies which occurred in the beginning of January were
corrected during a Boeing engineering site visit on January 9 and 10. The
data for January 11 through January 31 was used and then extrapolated to
reflect a full month's data. The space heating load and the auxiliary fossil
fuel energy for the DHW and space heating subsystems could not be determined
because of an unreliable gas totalizer. There was no solar energy contri-
bution to the DHW subsystem in January because the hot water thermosiphoning
system had been drained.

WEATHER CONDITIONS

During the month, total incident solar energy on the collector array was 16.8
million Btu for a daily average of 1305 Btu per square foot. This was below
the estimated average daily solar radiation for this geographical area during
January of 1784 Btu per square foot for a south-facirg plane with a tilt of 51
degrees to the horizontal. The average ambient temperature during January was
37F as compared with the long-term average for January o' 420F. The number
of heating degree-days for the month (based on a 650F reference) was 868, as
compared with the long-term average of 704.

THERMAL PERFORMANCE

Collector The total incident solar radiationon the collector array for the
month of January was 16.8 million Btu. During the period the collector loop







was operating, the total insolation amounted to 12.7 million Btu. The total
collected solar energy for the month of January was 3.6 million Btu, result-
ing in a collector array efficiency of 21 percent, based on total incident
insolation. Solar energy delivered from the collector array to storage was
2.8 million Btu. Operating energy required by the collector loop was 0.24
million Btu.

Storage Solar energy delivered to storage was 2.8 million Btu. There were
0.55 million Btu delivered from storage to the space heating subsystem.
Energy loss from storage was 2.2 million Btu. This loss represented 79 per-
cent of the energy delivered to storage. This "lost" energy is probably
infiltrating the living space and thus reducing the auxiliary thermal require-
ments. This supposition cannot be arithmetically substantiated for January
because the calculated actual space heating load is not available. The
average storage temperature for the month was 64F.

DHW Load The DHW load was 2.3 million Btu. Since there was no solar energy
contribution the load was satisfied by auxiliary fossil fuel energy (although
it could not be calculated because of the gas totalizer problem). The thermo-
siphoning subsystem in the attic has been drained until warm weather. A
daily average of 81 gallons of DHW was consumed at an average temperature of
1480F delivered from the tank.

Space Heating Load The space heating subsystem total load could not be calcu-
lated because the gas totalizer, which measures the gas consumption, was not
providing reliable data during January. A total of 1.0 million Btu of solar
energy was consumed as space heat, 0.55 million Btu delivered from storage
and the balance direct from the collector. The space heating subsystem con-
sumed a total of 0.65 million Btu of operating energy which is not considered
to be a solar energy system expense.


OBSERVATIONS

The site visit by Boeing and IBM engineers on January 10 and 11 resulted in
the correction of several problems. In addition, a gas totalizer was installed
to provide a more positive indication of gas consumption. There is still a
problem with the instrumentation of this totalizer and also with the instrumen-
tation of a water flowmeter in the auxiliary space heating subsystem. This
prevents the computation of the space heating load and also the auxiliary
fossil fuel energy contriubtion in the DHW and space heating subsystems. The
hot water thermosiphoning subsystem has been drained until all danger of
freezing has past.


ENERGY SAVINGS

The solar energy system provided a total fossil fuel energy savings of 1.7
million Btu; this savings was provided entirely by the space heating subsystem.






III. ACTION STATUS

A site visit by IBM and Boeing is scheduled for early February. The remaining
instrumentation anomalies will be investigated at that time.
