STEWART-TEELE-MITCHELL

JANUARY 1979

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 20F 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 1000F, 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
100F. 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 V1 directs the collector loop flow through a purge unit.

II. PERFORMANCE EVALUATION


INTRODUCTION

The solar energy system operated continuously during January. The average
daily insolation was approximately 56 percent of the long-term January average
for the area. The average daily temperature closely approached the long-term
average. The house was occupied in January and the DHW preheat subsystem
which had not operated previously was activated. Solar energy satisfied
a very small portion of the space heating and DHW loads during the month.


WEATHER CONDITIONS

During the month, total incident solar energy on the collector array was
6.1 million Btu for a daily average of 454 Btu per square foot. This was
below the estimated average daily solar radiation for this geographical area
during January of 818 Btu per square foot for a south-facing plane with a
tilt of 45 degrees to the horizontal. The average ambient temperature during
January was 210F as compared with the long-term average for January of 22F.
The number of heating degree-days for the month (based on a 650F reference)
was 1361, as compared with the long-term average of 1349.


THERMAL PERFORMANCE

System During January 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 inputs. Solar
energy collected was 0.63 million Btu versus an estimated 0.65 million Btu.
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 0.33
million Btu. System total solar fraction was 1 percent versus an estimated
6 percent.

Collector The total incident solar radiation on the collector array for the
month of January was 6.1 million Btu. During the period the collector loop
was operating, the total insolation amounted to 2.4 million Btu. The total
collected solar energy for the month of January was 0.63 million Btu, result-
ing in a collector array efficiency of 10 percent, based on total incident
insolation. Solar energy delivered from the collector array to storage was
0.58 million Btu, while solar energy delivered from the collector array
directly to the loads amounted to 0.024 million Btu. Energy loss during
transfer from the collector array to storage and loads was 0.030 million Btu.
This loss represented 5 percent of the energy collected. Operating energy
required by the collector loop was 0.037 million Btu.

Storage Solar energy delivered to storage was 0.58 million Btu. There were
0.33 million Btu delivered from storage to the DHW and space heating subsystems.
Energy loss from storage was 0.38 million Btu. This loss represented 65
percent of the energy delivered to storage. The storage efficiency was 35
percent: This is calculated as the ratio of the sum of the energy removed


3 4241








from storage and the change in stored energy, to the energy delivered to
storage. The average storage temperature for the month was 780F.

DHW Load The DHW subsystem consumed 0.20 million Btu of solar energy and
0.60 million Btu of auxiliary electrical energy to satisfy a hot water load
of 0.59 million Btu. The solar fraction of this load was 9 percent. Losses
from the DHW solar subsystem were 0.21 million Btu. The DHW subsystem
consumed a total of 0.081 million Btu of operating energy, resulting in an
electrical energy expense of 0.018 million Btu. A daily average of 31 gallons
of DHW was consumed at an average temperature of 1180F delivered from the
tank.

Space Heating Load The space heating subsystem consumed 0.13 million Btu
of solar energy and 16.2 million Btu of auxiliary thermal energy (equivalent
to 23.2 million Btu of auxiliary fossil fuel energy) to satisfy a space heating
load of 16.4 million Btu. The solar fraction of this load was 1 percent.
The space heating subsystem consumed a total of 0.62 million Btu of operating
energy, resulting in an electrical energy expense of 0.006 million Btu.


OBSERVATIONS

Although a substantial amount of solar energy was applied to preheating DHW,
the operating energy requirement of the solar DHW preheat subsystem exceeded
the added energy in the water entering the gas-fired auxiliary DHW tank from
the preheat tank. As measured across the solar heat exchanger in the DHW
preheat tank, 0.20 million Btu of solar energy were used in preheating incoming
city water. As measured by the temperature differential of the water entering
and leaving the DHW preheat tank, energy added to the DHW was only 0.07
million Btu. Energy required to operate the storage/DHW loop pump was 0.08
million Btu, resulting in a net loss of 0.01 million Btu of electrical energy
in the DHW preheating process during the month of January.


ENERGY SAVINGS

The solar energy system provided a fossil fuel energy savings of 0.22 million
Btu at an expense of 0.062 million Btu of electrical energy. The DHW subsystem
provided no electrical energy savings at an expense of 0.018 million Btu. The
space heating subsystem contributed a fossil fuel energy savings of 0.22
million Btu at an expense of 0.006 million Btu of electrical energy.

III. ACTION STATUS

Minor sensor problems existing in the energy collection and storage subsystems
will be addressed by Boeing during the next scheduled site visit. IBM has
recommended to Boeing that an additional flowmeter be added to the instru-
mentation and that currently installed flowmeter W200 be relocated.
