STEWART-TEELE-MITCHELL

NOVEMBER 1978

I. SYSTEM DESCRIPTION

The Stewart-Teele-Mitchell site is a single-family residence in Malta, New York.
The home has approximately 1900 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 432 square feet. The array faces south at an angle of 45
degrees to the horizontal. A glycol/water solution is the transfer medium
that delivers solar energy from the collector array to a heat exchanger.
Water is then used as the transfer medium that delivers solar energy from
the heat exchanger to storage, and to the space heating and DHW loads. Solar
energy is stored in the basement in a 1000-gallon insulated tank. Preheated
city water is stored in a 75-gallon preheat tank and supplied, on demand, to
a conventional 40-gallon DHW tank. When solar energy is insufficient to
satisfy the space heating load, an oil-fired furnace 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 five modes of solar operation.

Mode 1 Collector-to-Storage: This mode activates when the collector tempera-
ture exceeds the storage temperature by 20OF and terminates when a temperature
difference of 30F is reached. Solar energy is transferred through the heat
exchanger that transmits energy from the solar collection loop to the storage
loop. Collector loop pump P1 and storage loop pump P2 are operating.

Mode 2 Collector-to-Space Heating: This mode activates when mode 1 condi-
tions are satisfied and there is a demand for space heating. The collected
solar energy bypasses storage and flows directly to the solar heating coil in
the air-handling system. Mode diversion valve V2 is open.

Mode 3 Storage-to-Space Heating: This mode activates when there is a
demand for space heating, the temperature at the top of the storage tank
exceeds 100F, and solar energy from the collector is not available. Pump P3
is operating.

Mode 4 Storage-to-DHW Tank: This mode activates when the temperature at
the top of the storage tank exceeds the preheat tank water temperature by
10F. Pump P4 is operating.

Mode 5 Summer Mode, Collector-to-Vent: This mode activates when the col-
lector array output fluid temperature exceeds 2200F. The collected solar
energy is rejected through a fintube heat exchanger located outside the
dwelling. Valve VI directs the collector loop flow through a purge unit.

II. PERFORMANCE EVALUATION


INTRODUCTION

The solar energy system operated continuously during November except for the
first two days of the month. The average daily insolation was well above the
long-term November average for the area, but the average daily temperature
was below the long-term average. Solar energy satisfied a small portion of
the space heating load during the month with the system operating in both
modes 2 and 3. There was a small positive change in stored energy for the
month. Since the house was unoccupied, the DHW load was insignificant and
the DHW subsystem did not operate.


WEATHER CONDITIONS

During the month, total incident solar energy on the collector array was 11.5
million Btu for a daily average of 886 Btu per square foot. This was above
the estimated average daily solar radiation for this geographical area
during November of 780 Btu per square foot for a south-facing plane with a
tilt of 45 degrees to the horizontal. The average ambient temperature during
November was 370F as compared with the long-term average for November of
400F.


THERMAL PERFORMANCE

Collector The total incident solar radiation on the collector array for the
month of November was 11.5 million Btu. During the period the collector loop
was operating, the total insolation amounted to 6.6 million Btu. The total
collected solar energy for the month of November was 1.9 million Btu, resulting
in a collector array efficiency of 16 percent, based on total incident insola-
tion. Solar energy delivered from the collector array to storage was 1.6 mil-
lion Btu, while solar energy delivered from the collector array directly to the
loads amounted to 0.088 million Btu. Energy loss during transfer from the col-
lector array to storage and loads was 0.18 million Btu. Operational energy
required by the collector loop was 0.077 million Btu.

Storage Solar energy delivered to storage was 1.6 million Btu. There were
0.56 million Btu delivered from storage to the space heating subsystem.
Energy loss from storage was 0.96 million Btu. This loss represented 60
percent of the energy delivered to storage. The storage efficiency was 40
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 1100F.

DHW Load The DHW subsystem consumed no solar energy and 0.26 million Btu of
auxiliary electrical energy to satisfy a hot water load of 0.016 million Btu.









Since pump P4 did not operate during the month, no operational energy was
consumed. A daily average of one gallon of DHW was consumed at an average
temperature of 1260F delivered from the tank.

Space Heating Load The space heating subsystem consumed 0.45 million Btu
of solar energy and 4.7 million Btu of auxiliary thermal energy (equivalent
to 7.8 million Btu of auxiliary fossil fuel energy) to satisfy a space heating
load of 5.1 million Btu. The solar fraction of this load was 9 percent.
The space heating subsystem consumed a total of 0.90 million Btu of opera-
ting energy, resulting in an electrical energy expense of 0.16 million Btu.


OBSERVATIONS

Since this house was unoccupied, the November building temperature averaged
only 630F and hot water usage was insignificant. This resulted in an energy
load well below that which would have been expected if the house was occupied.

The demand for space heating during November, however, brought to light a
characteristic of the solar energy system which had not been observed previ-
ously. During November the system operated concurrently in modes 1 and 2.
When the system was collecting energy, the heat transfer fluid flow divided
at valve V2 and flowed to both the solar coil in the space heating air loop
and to the storage tank. Whether this mode reflects system design or is the
result of a leaky valve, it appears to be a desirable system operational
feature. The present instrumentation is not entirely adequate to measure
performance in this mode. The addition of a flowmeter between valve V2 and
the storage tank inlet and the movement of W200 to the furnace side of valve
V2 is required to accurately measure the flow in the two loops. Instrumenta-
tion deficiencies have been overcome by measuring the solar energy delivered
directly from the collector to space heating on the air side of the solar
coil, while the energy delivered concurrently to storage has been measured
using the flow in the liquid loop. This workaround procedure has the draw-
back of concealing solar system losses which occur between the output side of
the collector loop heat exchanger and storage/load.

The need for additional instrumentation to accommodate the actual operation
of the system will be assessed on the basis of system operation during December.


ENERGY SAVINGS

The solar energy system provided a total fossil fuel energy savings of 0.74
million Btu. The space heating subsystem contributed the entire energy
savings of 0.74 million Btu.

III. ACTION STATUS

A leak in the collector loop was repaired by the site contractor during the
first week in November. Minor problems with the collector loop instrumenta-
tion still cause the amount of solar energy collected to be slightly under-
stated. Boeing will address this problem during the next site visit.
