ALPHA CONSTRUCTION COMPANY

MAY 1979


I. SYSTEM DESCRIPTION


The Alpha Construction Company site is a single-family residence in Canton,
Ohio. Solar energy is used for space heating the home and preheating domestic
hot water (DHW). The solar energy system has an array of flat-plate collectors
with a gross area of 428 square feet. The array faces south at an angle of
37 degrees to the horizontal. Air is the transfer medium that delivers solar
energy from the collector array to storage and to the space heating and hot
water loads. Solar energy is stored in the basement in a 510-cubic-foot bin
containing 50,100 pounds of rock. The bin has concrete block walls and
polyurethane insulation. Preheated city water is stored in an 80-gallon
preheat storage tank and supplied, on demand, to a conventional 52-gallon DHW
tank. When solar energy is insufficient to satisfy the space heating load, a
heat pump in the air-handling unit provides auxiliary energy for space heating.
Similarly, an electrical heating element in the DHW tank provides auxiliary
energy for water heating. The system, shown schematically in Figure 1, has
four modes of solar operation.


Mode 1 Collector-to-Space Heating: This mode activates when the collector
is operating, a space heating demand exists, and the plenum temperature at
the top of storage is above the minimum value suitable for supplying heat to
the house. Collection begins when the temperature at the top of the collector
is higher by a minimum amount than the temperature in the plenum at the bottom
of storage. Heated air is passed through the plenum at the top of storage
and circulated through the house by the heat pump air-handling unit before
being returned to the collector.


Mode 2 Collector-to-Storage: This mode activates when the collector is
operating and there is either no demand for space heating or the plenum

temperature at the top of storage is below the miniiiumi value for supplying
heat to the house.


Mode 3 Storage-to-Space Heating: This mode activates when there is a
demand for space heating, and the plenum temperature at the top of storage is
above the minimum value for supplying heat to the house. The fan in the air-
handling unit draws air from the bin, circulating it through the house and
back to storage.


Mode 4 Domestic Water Preheating: This mode activates when the collector is
operating and when the temperature at the top of the collector indicates a
minimum value for hot water heating, which must be above the plenum tempera-
ture at the bottom of storage.



II. PERFORMANCE EVALUATION



INTRODUCTION


The site was unoccupied in May and the solar energy system operated continu-
ously during the month. Total solar energy collected was 4.2 million Btu and
the total solar energy used was 0.43 million Btu or 10 percent of the collec-
ted energy. The change in stored energy was 0.069 million Btu and the total
system losses amounted to 3.7 million Btu. Solar energy satisfied 88 per-
cent of the space heating requirements. There was no demand for hot water
during the month. The solar energy system incurred an electrical energy
expense of 0.55 million Btu.



WEATHER CONDITIONS


During the month, total incident solar energy on the collector array was
19.0 million Btu for a daily average of 1432 Btu per square foot. This was








below the estimated average daily solar radiation for this geographical area
during May of 1533 Btu per square foot for a south-facing plane with a tilt
of 37 degrees to the horizontal. The average ambient temperature during May
was 580F as compared with the long-term average for May of 59F. The number
of heating degree-days for the month (based on a 65'F reference) was 274, as
compared with the long-term average of 231. The number of cooling degree-
days was 43, as compared with the average of 36.



THERMAL PERFORMANCE


System During May the solar energy system performed somewhat poorer than
expected. The expected performance was determined from a modified f-chart
analysis using measured weather and subsystem loads as input. Solar energy
used by the system was estimated by assuming that all energy collected would
be applied to the load. Actual solar energy used was 0.43 million Btu
versus an estimated 0.7 million Btu. System total solar fraction was 88
percent versus an estimated 100 percent.


Collector The total incident solar radiation on the collector array for the
month of May was 19.0 million Btu. During the period the collector loop was
operating, the total insolation amounted to 17.2 million Btu. The total
collected solar energy for the month of May was 4.2 million Btu, resulting in
a collector array efficiency of 22 percent, based on total incident insolation.
Solar energy delivered from the collector array to storage was 3.8 million
Btu, while solar energy delivered from the collector array directly to the
loads amounted to 0.18 million Btu. Energy loss during transfer from the
collector array to storage and loads was 0.24 million Btu. This loss repre-
sented 6 percent of the energy collected. Operating energy required by the
collector loop was 0.37 million Btu.


Storage Solar energy delivered to storage was 3.8 million Btu. There were
0.25 million Btu delivered from storage to the space heating subsystem. Energy







loss from storage was 3.5 million Btu. This loss represented 92 percent of
the energy delivered to storage. The storage efficiency was 8 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 storacje. The average
storage temperature for the month was 113F.


DHW Load Because the home was unoccupied in May, there was no demand for
hot water. A total of 0.18 million Btu of solar energy was used to heat the
water in the preheat tank. The DHW subsystem consumed a total of 0.27
million Btu of operating energy, resulting in an electrical energy expense of
0.27 million Btu. An additional 0.26 million Btu of auxiliary electrical
energy were used by the hot water tank to maintain the temperature. The
average temperature of the water in the DHW tank was 1190F.


Space Heating Load The measured space heating load for the unoccupied home
during May was 0.29 million Btu. The solar energy system provided 0.25
million Btu. The remaining load of 0.035 million Btu was satisfied by an
auxiliary electrical heat pump and an electrical heating element at an elec-
trical energy consumption of 0.011 million Btu. The space heating subsystem
consumed an additional 0.036 million Btu of operating energy. A net electrical
energy savings of 0.096 million Btu were obtained from the solar portion of
the space heating subsystem.



OBSERVATIONS


The solar energy site was unoccupied during May and presented a minimum space
heating load due to a low thermostat setting of 62F and relatively mild
ambient temperature. More solar energy than required was collected to
satisfy the space heating load. The uncontrolled energy escape from storage
of 3.5 million Btu into the conditioned space and the outside environment
caused electrical energy to be expended for 12 percent of the space heating
load by the auxiliary heat pump.







During the month, the collector air-flow sensor (W100) continued to read
lower values of air flow than previously measured. The cause for this reduced
air flow remains undetermined; however, a faulty sensor is suspected. There-
fore, collected energy for the month may be slightly higher than stated in
the attached report. The losses from storage would be increased by the same
amount, since the measured energy delivered to the load is not affected.


The DHW preheat loop expended more operating energy than the amount of solar
energy transferred to the DHW preheat tank. The configuration of the DHW
preheat loop permits solar energy transfer to the preheat tank only when
collection is occurring. A separate air blower is required by this subsystem
and adds significantly to operating costs. Frequently the heated air from the
collector at the beginning or end of the collection period is cooler than the
temperature of the water in the preheat tank. The operation of the preheat
loop, which is independent of the water temperature in the tank, extracts
energy from the tank during these periods. During periods of heating from
storage, an induced air flow occurs through the DHW loop. A portion of the
unmeasurable energy loss from storage may escape through this air path.
During the cooling season the storage subsystem must be operated in order to
operate the DHW preheat loop and energy that is not used by the DHW subsystem
is collected in storage. However, the energy losses from storage transfer
into the conditioned space and add to the space cooling loads. These energy
losses reduce the energy savings obtained by the DHW subsystem.



ENERGY SAVINGS


The solar energy system incurred a total electrical energy expense of 0.55
million Btu. The space heating subsystem provided an electrical energy
savings of 0.096 million Btu, but this was eliminated due to the expense of
operating the DHW subsystem (0.27 million Btu) and the collection subsystem
(0.37 million Btu).









III. ACTION STATUS


Boeing conducted a preliminary air-mapping survey in October which revealed
significant leaks in the energy collection and storage subsystems. Sealing
the accessible leaks would only provide minimal improvement.


Boeing has been advised of the reduced air-flow measurements of W100.
A schedule for corrective action has not been established.
