I. SYSTEM DESCRIPTION

The Billings Shipping solar site, located in Billings, Montana, is an
enclosed freight distribution facility with 4,900 square feet of heated
office space. The solar energy system is designed to provide 54 percent
of the annual heating demand. The system has a roof-mounted flat-plate
collector array that faces 10 degrees east of south at an angle of 50
degrees from the horizontal. The collector array manufactured by Lennox
Industries, Inc., has a gross area of 1,848 square feet and uses a 50 per-
cent propylene glycol and water solution for the energy transport fluid.

The collected solar energy is stored in a 2,500-gallon water tank which
is insulated with two inches of polystyrene and buried three feet below
the surface of the ground. Solar energy may be transferred to the space
heating subsystem from this tank or transferred directly from the energy
collection subsystem. This solar heated water passes through the solar
portion of the air-handler unit space heating coil to provide space
heating. Auxiliary space heating is obtained from heated water flowing
through a separate loop of the air-handler unit. Auxiliary energy is
supplied by a gas-fired hot water boiler.


The system, shown schematically in Figure 1, has four modes of operation.

Mode 1 Collector-to-Heat Exchanger: This mode is entered when the
collector surface reaches 130F. Pumps Pl and P2 are activated simul-
taneously at this temperature and are shut off whenever the surface
temperature falls below 1000F. Collector loop fluid circulates through
the collector and heat exchanger. In this mode, pump P2 circulates solar
heated water through the tube side of heat exchanger and then through valves
VI and V2, thus, bypassing storage and the heat exchanger coil located in
the space heating duct. If the collector fluid leaving pump PI is above

Figure 1. BILLINGS SHIPPING SOLAR ENERGY SYSTEM SCHEMATIC








1950F, valve V4 is switched to the heat rejector position and heat re-
jector fan power is applied.

Mode 2 Heat Exchanger-to-Storage: This mode is entered when Mode 1 is
active and when the temperature of the water leaving valve V2 is higher
than storage, valve Vi opens, thus permitting water from the heat exchan-
ger to be directed through storage. Otherwise, valve Vi is positioned to
bypass storage.

Mode 3 Heat Exchanger-to-Load: This mode is entered when Mode 1 is
active and when there is a space heating demand. Water from the heat
exchanger is directed through space heating coils in the air-handler
unit by valve V2. When the space heating demand is satisfied, valve
V2 is positioned to bypass the heating coils.

Mode 4 Storage-to-Load: This mode is entered if there is a space
heating demand when the heat exchanger loop is off and the storage tempera-
ture is above 80F. Water is circulated by pump P3 from storage through
valve VI to the air-handler unit and back to storage. Valve V2 directs
the water in the air-handler unit to the space heating coils.


II. PERFORMANCE EVALUATION

The system performance evaluations discussed in this section are based
primarily on the analysis of the data presented in the attached computer-
generated monthly report. This attached report consists of daily site
thermal and energy values for each subsystem, plus environmental data.
The performance factors discussed in this report are based upon the
definitions contained in NBSIR 76-1137, Thermal Data Requirements and
Performance Evaluation Procedures for the National Solar Heating and
Cooling Demonstration Program.


A. Introduction

The solar energy system operated throughout May, satisfying 28 percent
of the space heating demand. The building temperature was maintained at








an average of 74F, with an outside ambient temperature average of 560F.
The use of solar energy resulted in a fossil energy savings of 7.7 mil-
lion Btu at an electrical energy expense of 1.1 million Btu.

B. Weather

The measured average outside daily temperature for May of 560F was near
the long-term predicted value of 550F. The maximum average daily tem-
perature was 710F, and the minimum was 380F. The average measured in-
solation was 1,614 Btu/ft 2-day, which was within 1.5 percent of the 1,639
Btu/ft2-day long-term estimate.

C. System Thermal Performance

Collector Of 92.4 million Btu of solar energy incident on the collector
array in May, 77.8 million Btu were available during collector subsystem
operation, 20.7 million Btu were collected and 1.6 million Btu were re-
jected. The operation of the energy collection and storage subsystem
pumps Pl and P2 required 0.9 million Btu (269 kwh) of electrical energy.
The measured collector array efficiency was 22 percent.

Storage Of the 20.7 million Btu of solar energy collected, 14.0 million
Btu were transferred to the hot water loop by the heat exchanger. A
total of 11.0 million Btu was delivered to storage, and 3.7 million Btu
were removed from storage for distribution to the space heating subsystem.
The net storage energy increase measured during the month was 0.4 million
Btu, and 1.1 million Btu were lost by the storage loop in the distribu-
tion from the collector to storage. The net loss to the tank surround-
ings was 6.9 million Btu, and the efficiency was 37 percent. The average
tank temperature was 1400F.

Space Heating Load While transferring energy from the collectors to
storage, 1.9 million Btu were delivered to the load, with a 0.04 mil-
lion Btu loss from the load subsystem to the surroundings. During the








storage-to-load mode, 3.7 million Btu were transferred to the load sub-
system, with a 0.9 million Btu loss. The net solar energy delivered to
the load was 4.6 million Btu. The gas-fired boiler consumed 28.9 mil-
lion Btu of fossil fuel and contributed 11.6 million Btu to the space
heating subsystem. The total space heating load for the month was 16.3
million Btu, and the resulting solar fraction was 28 percent.


The space heating subsystem required 2.0 million Btu (574 kwh) of elec-
trical operating energy; 1.8 million Btu (530 kwh) were required to
operate the conventional air circulation system and boiler, and were
not charged against the solar energy system savings.


D. Observations


Of the 20.7 million Btu of solar energy collected, 1.6 million Btu were
rejected, 0.4 million Btu were added to storage, 4.6 million Btu were
delivered to the space heating load and 14.1 million Btu were the net
loss. This loss was distributed as follows: 5.1 million Btu between
the collector and heat exchanger outlet, 1.1 million Btu between the
heat exchanger and storage while storing energy, 6.9 million Btu from
storage to surroundings, and 1.0 million Btu from load subsystem to sur-
roundings while provided space heating.


During May, the collector loop operated while the collector absorber
plate temperature ranged above the 1000F collector operating temperature
but was less than storage temperature. Valve Vl remained in the heat-
exchanger-to-storage position, and storage energy was transferred to the
collector loop. This operation was recorded in the hourly performance
factors in the form of negative values of collected energy and energy-
to-storage. The net effects on the monthly performance factors were
lowered collector efficiency, storage energy and solar fraction.


On May 8, the collector loop operated for short periods of time, col-
lecting 0.1 million Btu. The collected energy transferred across the








heat exchanger was insufficient to heat the water in the storage lines to
storage operating temperature, resulting in the negative value of energy
to storage.

E. Energy Savings

The fossil fuel energy savings value was 7.7 million Btu (2,260 kwh) at
an expense of 1.1 million Btu (314 kwh) of electrical energy.

III. ACTION STATUS

The collector heat exchanger outlet sensor appears to read inaccurately,
and an alternate sensor is being used at this time.

It has been recommended that valve Vl be positioned to bypass storage
when the collector heat exchanger outlet temperature decreases below
storage temperature.
