MONTHLY PERFORMANCE REPORT


HELIO-THERMICS, INC.
HOUSE LOT 6

MAY 1979


I. SYSTEM DESCRIPTION


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 the DHW. The system, shown schemat-
ically 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 26F higher
than the storage temperature. This mode terminates when the temperature
difference between the collector and storage is less than 16"F.

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


Although the site was occupied during May, no attempt was made to collect or
store solar energy. The DHW thermosiphoning system provided 0.52 million
Btu of solar energy to the hot water load of 1.3 million Btu.


There was a space heating demand of 0.32 million Btu which was primarily
satisifed with auxiliary thermal energy and only a negligible quantity of
solar energy. The thermal energy provided by conventional methods to satisfy
the conditioned space heating load also circulates through storage and, in
effect, heats the storage bin. The same relatively low storage temperatures,
however, provided a source for cool air during the warm daytime hours.
Because of the fluctuating temperature, which results in a heating load
during the night and a cooling load during the day, the system has not been
fully converted to a summer mode of operation. In a full summer mode, the
heating requirements are assumed to be insignificant (until fall) and cool
air is intentionally transferred to storage during the night for daytime use.



WEATHER CONDITIONS


During the month, total incident solar energy on the collector array was
17.4 million Btu for a daily average of 1351 Btu per square foot. This was
below the estimated average daily solar radiation for this geographical area
during May of 1438 Btu per square foot for a south-facing plane with a tilt
of 51 degrees to the horizontal. The average ambient temperature during May
was 670F as compared with the long-term average for May of 690F.









THERMAL PERFORMANCE


Collector The total incident solar radiation on the collector array for the
month of May was 17.4 million Btu, although no attempt was made to collect
or store solar energy during this period.


Storage Solar energy was not delivered to storage, although air from the
living area was circulated through the relatively cool storage bin to provide
cooler inside ambient air. Therefore, the thermal energy mass in storage
was intentionally reduced by 0.60 million Btu. This quantity appears as a
negative value in the transferredl from" column of the attached report (see
Storage Performance). The average storage temperature for the month was
710F.


DHW Load The DHW subsystem consumed 0.52 million Btu of solar energy and
at least 0.78 million Btu of auxiliary fossil fuel energy to satisfy a hot
water load of 1.30 million Btu. Losses from the DHW subsystem are unknown.
The DHW theroasiphoning subsystem does not consume operating energy, resulting
in a fossil fuel energy savings of 0.87 million Btu. A daily average of 70
gallons of DHW was consumed at an average temperature of 1420F delivered
from the tank.

Space Heating Load The space heating subsystem consumed a negligible
quantity of solar energy and 0.53 million Btu of auxiliary fossil fuel
energy to satisfy a space heating load of 0.32 million Btu. The space
heating subsystem consumed a total of 0.06 million Btu of operating energy.



OBSERVATIONS


The gas flow totalizer used to 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 the problem is corrected.









ENERGY SAVINGS


The solar energy system provided a fossil fuel energy savings of 0.88 million
Btu at an electrical energy operating expense of 0.012 million Btu.



III. ACTION STATUS


Boeing will replace the gas totalizer before the next heating season.
