MONTHLY PERFORMANCE REPORT


HELIO-THERMICS, INC.
HOUSE LOT 6

FEBRUARY 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 degrees
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 demand
for space heating and the collector supply-duct temperature is 260F 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 tempera-
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 heating
is required and the collector supply-duct air temperature is 10F higher than
the building ambient air temperature. This mode terminates when the tempera-
ture difference drops to less than 60F or the space heating requirement is
satisfied.

Mode 4 Auxiliary Energy-to-Space Heating: This mode activates when space
heating is required and thermal energy is not available from the collectors
or storage. An electrical heating element in the hot air supply-duct remains
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 during the month of February and the solar energy system
operated continuously during the month. The measurable solar energy satisfied
14 percent of the space heating requirements. The solar energy system pro-
vided fossil fuel energy savings of 1.1 million Btu.

To prevent the possibility of water freezing in the thermosiphoning subsystem,
this solar energy system component (located in the attic) has been drained
until warmer weather.

In this report the space heating load represents data from the last 14 days of
February which was used and extrapolated to reflect the entire month. Because
the average ambient temperature for the last 14 days was 430F and the average
for the first 14 days was 330F, a significant bias has been introduced to some
monthly totals. However, the data will provide some insight into solar energy
system performance.


WEATHER CONDITIONS

During the month, total incident solar energy on the collector array was 13.3
million Btu for a daily average of 1146 Btu per square foot. This was below
the estimated average daily solar radiation for this geographical area during
February of 1715 Btu per square foot for a south-facing plane with a tilt of


1 4.'40




i



51 degrees to the horizontal. The average ambient temperature during February
was 380F as compared with the long-term average for February of 44F. The
number of heating degree-days for the month (based on a 65F reference) was
757, as compared with the long-term average of 577.

THERMAL PERFORMANCE

Collector The total incident solar radiation on the collector array for the
month of February was 13.3 million Btu. During the period the collector loop
was operating, the total insolation amounted to 9.4 million Btu. The total
collected solar energy for the month of February was 2.7 million Btu, result-
ing in a collector array efficiency of 20 percent, based on total incident
insolation. Solar energy delivered from the collector array to storage was
2.0 million Btu. Energy loss during transfer from the collector array to
storage and loads was 0.19 million Btu. This loss represented 7 percent of
the energy collected. Operating energy required by the collector loop was
0.18 million Btu.

Storage Solar energy delivered to storage was 2.0 million Btu. There were
0.20 million Btu delivered from storage to the space heating subsystem.
Energy loss from storage was 1.7 million Btu. This loss represented 82 per-
cent of the energy delivered to storage. This "lost" thermal energy is proba-
bly entering the living area and contributing to the lower-than-expected space
heating load. The predicted space heating load based upon actual ambient
temperature was 5.7 million Btu, considerably higher than the actual load of
2.9 million Btu. The storage efficiency was 18 percent: This is calculated
as the ratio of the sum of the energy removed from storage and the change in
stored energy, to the energy delivered to storage. The average storage tempera-
ture for the month was 640F.

DHW Load The DHW load was 2.4 million Btu, of which there was no solar
contribution because the thermosiphoning subsystem was drained. A daily
average of 91 gallons of DHW was consumed at an average temperature of 153F
delivered from the DHW tank.

Space Heating Load The space heating subsystem consumed 0.68 million Btu of
solar energy and 4.1 million Btu of auxiliary fossil fuel energy to satisfy a
space heating load of 2.9 million Btu. This space heating load total reflects
the bias introduced by using the last half of the February data as the basis
for computing the monthly total. The solar fraction of this load was 14 per-
cent. The space heating subsystem consumed a total of 0.58 million Btu of
operating energy in order to distribute both solar energy and auxiliary thermal
energy.


OBSERVATIONS

The instrumentation anomalies which created the need to extrapolate data have
been corrected as a result of a site visit by IBM on February 14. Although
unrelated, it was observed on February 16 that the gas totalizer used to





4 4240









quantify the gas consumption is not providing valid data. The measurement of
auxiliary thermal energy consumption in the DHW subsystem will not be available
until this problem is corrected.


ENERGY SAVINGS

The solar energy system provided a total fossil fuel energy savings of 1.1
million Btu.


III. ACTION STATUS

Boeing will schedule a site visit in the near future in order to correct the
erroneous gas totalizer data readings.
