DESIGN CONSTRUCTION

MAY 1979

I. SYSTEM DESCRIPTION


The Design Construction site is a single-family residence in Bigfork, Montana.
The home has approximately 1800 square feet of conditioned space. 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 792 square feet. The array faces south at an angle of 45
degrees to the horizontal. Water is the transfer medium that delivers solar
energy from the collector array to storage and from storage to the space
heating and hot water loads. This water is drained from the collector when
the collector pump is not operating. Solar energy is stored in a 1400-gallon
water tank located in the conditioned space. The cylindrical tank has 6-inch
concrete walls with 2-inch expanded polyurethane insulation. Preheated city
water is stored in a 65-gallon DHW tank. When solar energy is insufficient
to satisfy the space heating load, an electrical heating element in the
boiler provides auxiliary energy for space heating. Similarly, an electrical
heating element in the DHW tank provides auxiliary energy for water heating.
Solar energy in the storage tank is supplemented by auxiliary energy provided
by a hydro-heater fireplace which has a heat-exchanger water jacket around
the chimney. When the fireplace is used, water is circulated from the storage
tank through the fireplace and chimney heat eAchanger, thereby accumulating
additional energy which is returned to the storage tank. Energy from the
storage tank is transferred to the DHW tank through an in-tank heat e\chadner.
Hot water used for space heating is passed from sturdaql through the electric
boiler and then through a four-zone hydronic heating system. Two fans are
installed in the small enclosed chamber above the fireplace in whiLh the
fireplace pump (P4) and the fireplace control sensur are 1.Lated. These ftns
are used to cool the chamber ambient and to circulate the warni chamber air
into the living space. Both fans operate in pdarallel with the fireplace
pump. The System, shown schematically in Fiqure 1, ha. tour miiodesj of 'ilar
operation, each of which is independent of the others.

Mode 1 Collector-to-Storage: This mode activates when there is a tempera-
ture difference of 9F between the control sensor located in the collector and
the control sensor in the storage tank. Water is circulated from the storage
tank through the collector and back to the tank. This circulation continues
until the temperature difference between the two control sensors decreases to
30F, at which point the circulating pump turns off. When the pump stops
operating, water is drained from the collector and returned to the storage
tank.


Mode 2 Storage-to-Space Heating: This mode activates when any of the four
zones demand space heating. The thermostat of the zone demanding heat will
activate the solenoid-operated control valve for that zone. The thermostat
will also activate the circulating pump to allow heated water to circulate
from the storage tank, through the boiler, to the appropriate zone (via its
control valve) and back to the storage tank. Water continues to circulate as
long as any zone demands heat. The electric boiler will provide auxiliary
energy if the temperature of the water circulating through the boiler drops
below 1100F (set point). When the space heating demand is satisfied, the
circulating pump turns off and all open-zone control valves close.


Mode 3 Storage-to-DHW Heat Exchanger: This mode activates when the tempera-
ture difference between a control sensor in the storage tank and a control
sensor on the surface of the DHW tank reaches 9CF and terminates when the
temperature difference drops to 5"F. If the water temperature in the hot
water tank falls below the setting of its thermostat, the electric irlmmersion
heater turns on to provide auxiliary energy to the water in the hot water
tank. This mode also terminates if the temperature in the storage tank, as
indicated by another control sensor in the storage tank, falls below 80 F
(set point).


Mode 4 Fireplace-to-Storage: This mode dctivdtes when there is a tempera-
ture difference of 90F between a Lontrul sensor luILated in the fir elLidLe nir
another control sensor in the storage tank. (This OCLurS when thte lireplae

energy which is returned to storage. This mode continues until the tempera-
ture difference between the two control sensors drops to 30F, at which point
the pump turns off and the mode terminates. Both fans in the enclosed chamber
above the fireplace also operate in parallel with the pump while in this mode.



II. PERFORMANCE EVALUATION



INTRODUCTION


The site was occupied in May and the solar energy system operated continuously
during the month. Total solar energy collected was 10.9 million Btu and
the total solar energy used was 3.8 million Btu or 35 percent of the
collected energy. The change in stored energy was 0.19 million Btu and
the total system losses amounted to 9.4 million Btu. Solar energy
satisfied 94 percent of the DHW requirements and 93 percent of the space
heating requirements. The solar energy system provided an electrical
energy savings of 3.5 million Btu. The performance factors are discussed
below and are presented in the accompanying report forms.



WEATHER CONDITIONS


During the month, total incident solar energy on the collector array was
36.9 million Btu for a daily average of 1505 Btu per square foot. This
was below the estimated average daily solar radiation for this geographical
area during May of 1534 Btu per square foot for a south-facing plane
with a tilt of 45 degrees to the horizontal. The average ambient temperature
during May was 51F and was equal to the long-term average for May. The
number of heating degree-days for the month (based on a 650F reference)
,'s 403, as compared with the long-term average of 437.

THERMAL PERFORMANCE


System During May the solar energy system performed approximately the same
as 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 3.8 million Btu versus
an estimated 4.0 million Btu. System total solar fraction was 94 percent
versus an estimated 100 percent.


Collector The total incident solar radiation on the collector array for the
month of May was 36.9 million Btu. During the period the collector loop was
operating, the total insolation amounted to 28.4 million Btu. The total
collected solar energy for the month of May was 10.9 million Btu, resulting
in a collector array efficiency of 30 percent, based on total incident insola-
tion. Solar energy delivered from the collector array to storage was 5.4 mil-
lion Btu. Energy loss during transfer from the collector array to storage was
5.5 million Btu. This loss represented 50 percent of the energy collected.
Operating energy required by the collector loop was 0.14 million Btu.


Storage Solar energy delivered to storage was 5.4 million Btu and auxiliary
energy contribution to storage was 0.090 million Btu. There were 7.9 million
Btu delivered from storage to the DHW and space heating subsystems. The
storage efficiency was 147 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 temperature for the
month was 1510F.


DHW Load The DHW subsystem consumed 3.7 million Btu of solar energy, 0.053
million Btu of auxiliary energy from storage and 0.12 million Btu of auxiliary
electrical energy to satisfy a hot water load of 1.3 million Btu. The solar
fraction of this load was 94 percent. Losses from the DHW subsystem were 2.5
million Btu. The DHW subsystem consumed a total of 0.12 million Btu of
operating energy, resulting in an electrical energy savings of 3.5 million
Btu. A daily average of 58 gallons of DHW was consumed at an average tempera-
ture of 146'F delivered from the tank.









Space Heating Load The space heating subsystem consumed 0.16 million Btu of
solar energy, 0.005 million Btu of auxiliary thermal energy from storage, and
no auxiliary electrical energy to satisfy a space heating load of 0.17 million
Btu. The solar fraction of this load was 93 percent. The space heating
subsystem consumed a total of 0.007 million Btu of operating energy, resulting
in an electrical energy savings of 0.15 million Btu.



OBSERVATIONS


Data was lost for a 62-hour period at the end of the month due to a power
shutdown at the site and also because the phone lines were 3ccidently cut
during construction work. Therefore, no data appear in the report forms for
the last three days of May.


Intermittent failure of the flowmeter (W400) in the storage/space heating loop
continued throughout the month. The meter intermittently indicated zero flow
even though other sensor data show that the related pump (P3) was operating.
An estimated flow rate was used on those scans where W400 failed (approximately
15 percent of the scans where flow occurred). Therefore, the performance
factors derived from this flow (energy output from storage and heating load)
were based, in part, on estimated flow. A replacement sensor is at the site
and will be installed by the grantee in June.


Storage efficiency continued to exceed 100 percent by a considerable amount.
Since energy input to storage during May was primarily from the collector loop
and energy output from storage was primarily to the hot water loop, analysis
will focus on these two loops in an attempt to determine the cause of the
storage energy imbalance. The high transport losses in the storage/DHW loop
(4.1 million Btu) combined with the high losses in the DHW subsystem (65
percent of energy input) suggest that energy measurements in this loop may be
high. High measurements ;n this loop, in addition to explaining the high
transport and subsystem losses, would also contribute to the hiqh value for
storage efficiency.





6








The total solar energy delivered to storage during May was 6.9 million Btu.
However 1.5 million Btu of this energy was returned by storage to the collector
loop during the start-up phase of mode 1, resulting in a net input of 5.4
million Btu of solar energy to storage for the month. Therefore, of the 5.4
million Btu energy loss in the collector loop during mode 1 operation, 1.5
million Btu (28 percent) of the loss was start-up phase losses; the remainder
was due to transport losses between the collector array and storage.



ENERGY SAVINGS


The solar energy system provided a total electrical energy savings of 3.5
million Btu. The DHW subsystem provided an electrical energy savings of 3.5
million Btu, while the space heating subsystem contributed an electrical
energy savings of 0.15 million Btu.



III. ACTION STATUS


The flow sensor (W400) in the storage/space heating loop will be replaced
by the grantee. The replacement meter is at the site.
