MONTHLY PERFORMANCE REPORT


HELIO-THERMICS, INC.
HOUSE LOT 6

APRIL 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 26'F 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 10OF 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 in April and the solar energy system operated contin-
uously during the month. Solar energy satisfied 12 percent of the space
heating requirements and provided a fossil fuel energy savings of 0.081 mil-
lion 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 all danger of freezing is past.


For 16 days during April, the solar energy system was in a partial summer
mode; that is, no attempt was made to collect and transport solar energy to
the storage subsystem. This method of operation reduces the solar energy
migrating into the house during warm days, but also creates an undesirable
effect when space heating is required during the night. Occasionally, when
solar energy is not being transported to storage, the storage temperature will
drop below the temperature in the living area and become ineffective as a
source of thermal energy. However, the thermal energy provided by conven-
tional methods to satisfy the heating load also circulates through the storage
bin and, in effect, heats the storage bin. This undesirable method of opera-
tion occurs during transitional months and has a small impact on the long-term
effectiveness of the solar energy system.



WEATHER CONDITIONS


During the month, total incident solar energy on the collector array was
18.1 million Btu for a daily average of 1453 Btu per square foot. This was
below the estimated average daily solar radiation for this geographical area
during April of 1546 Btu per square foot for a south-facing plane with a tilt







of 51 degrees to the horizontal. The average ambient temperature during April
was 590F as compared with the long-term average for April of 61F.



THERMAL PERFORMANCE


Collector The total incident solar radiation on the collector array for the
month of April was 18.1 million Btu. During the period the collector loop was
operating, the total insolation amounted to 5.0 million Btu. The total col-
lected solar energy for the month of April was 1.2 million Btu, resulting in a
collector array efficiency of 7 percent, based on total incident insolation.
Solar energy delivered from the collector array to storage was 0.90 million
Btu. Energy loss during transfer from the collector array to storage was
0.30 million Btu. This loss represented 25 percent of the energy collected.
Operating energy required by the collector loop was 0.11 million Btu.


Storage Solar energy delivered to storage was 0.90 million Btu. During the
latter part of April the system was occasionally operating in a storage-to-
load mode. Because the storage temperature was below the living area tempera-
ture, relatively cool air was transported from storage, through the conven-
tional space heating subsystem, through the living area and then back to
storage. This situation results in the storage temperature being increased by
the conventional space heating subsystem. The numerical effect of this operat-
ing method is indicated as a negative 0.26 million Btu being transported from
storage. The average storage temperature for the month was 760F.


DHW Load There was no solar energy contribution to the DHW load of 1.4
million Btu because the thermosiphoning subsystem had been drained. A daily
average of 63 gallons of DHW was consumed at an average temperature of 153F
delivered from the tank.


Space Heating Load The space heating subsystem consumed 0.049 million Btu of
solar energy and 0.35 million Btu of auxiliary thermal energy to satisfy a








space heating load of 0.40 million Btu. The solar fraction of this load was
12 percent. The space heating subsystem consumed a total of 0.091 million Btu
of operating energy in order to distribute both solar and auxiliary thermal
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 this problem is corrected.



ENERGY SAVINGS


The solar energy system provided a total fossil fuel energy savings of 0.081
million Btu at an electrical energy expense of 0.14 million Btu.



III. ACTION STATUS


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