MONTHLY PERFORMANCE REPORT
REEDY CREEK UTILITIES
JUNE 1979


I. SYSTEM DESCRIPTION


The Reedy Creek site is a two story, 6,100 square foot concrete block
office building located in Lake Buena Vista, Florida. The solar energy
system is designed to provide space heating, domestic hot water and
space cooling.


The collector subsystem is composed of a horizontal array of 16 parabolic
trough collectors, manufactured by AAI Corporation, with tracking absorber
tubes. The collector array is an integral part of the building's roof,
with the reflector troughs oriented so that each major axis is in an
east-west direction. The 16 absorber tubes are moved in unison in a
north-south direction by the solar tracking system. The total collector
aperture area is 3,840 square feet. Water is used as the heat collec-
tion, transfer, and storage medium. Collected solar energy is stored in
a 10,000-gallon hot water tank, located adjacent to the building and
shaded by the roof. Domestic hot water is provided by a heat exchanger
immersed in this tank. Space heating is provided by circulation of hot
water from the storage tank through heat exchangers located in the
central air distribution system. No auxiliary energy is provided for
either domestic hot water or space heating.


A 25-ton absorption chiller utilizes hot water from solar storage to
provide chilled water to a 10,000-gallon cold water storage tank. For
space cooling, water from this cold tank is circulated through heat
exchangers located in the building's central air distribution system.
Auxiliary cooling is provided by supplemental cold water from the
utility district's central chiller plant, which is powered by fossil
fuels.








The system, shown schenmtically in Figure 1, has five modes of solar
operation.


Modt 1 Collector-to-Storage: This mode is entered when the collector
dbsorJer plate temperature is 100F higher than the temperature at the
bottori of the hot storage tank (water solar thermal storage). Water is
circulated through the collector array-storage loop by pump P1 until the
temperature of the water at the bottom of storage rises to within 30F'of
that of the collector absorber plate.


Mode 2 Storage-to-Space Heating: This mode is entered when the
temperature falls below the setting of the thermostats located in the
occupied areas. Since this is the only means of space heating avail-
able, no minimum tank temperature is specified. Pump P2 causes hot
water to flow directly from the storage tank to the heat exchanger in
the air-handling unit, and back to the storage tank.


Mode 3 Comestic Hct Water Heating: Domestic hot water (DHW) is provided
by passing city supply water through a heat exchanger immersed in the
solar thermal storage tank. No conventional water heater exists, thus
water is heated only upon demand. A tempering valve is used when neces-
sary to reduce the temperature of water leaving the heat exchanger. If
the water is too hot, cold supply water is mixed with it in the tempering
valve before going to the DHW line.


Mode 4 Chilled Water Production: This mode is entered when the
temperature of the water in the top of the solar thermal storage tank
is at or above the generator operating temperature (nominally 1800F) and
that of t:e water at the bottom of the 10,000-gallon chilled water
storage is greater than 450F. Hot water is drawn from the solar thermal
storage tank to operate the generator section of the absorption chiller
and cold water is circulated through the chiller from the chilled water
storage. Energy is removed from the cold water, lowering its tempera-
ture; the energy is rejected through the cooling tower, and the cold
water returns to the chilled water storage tank. Whenever the temperature

of tht water going to the generator exceeds the upper limit of 1950F,
the water is tempered with cooler water returning through valve V4.


Modt: 5 Space Cooling: The space cooling mode is initiated when the
building temperature exceeds the setting of the conditioned space
thenrnostat. Chilled water from the chilled water storage is then
circulated by pump P6 to the heat exchangers in the building air distribu-
tior system. If the chilled water storage system is not able to meet
the cooling load, an auxiliary chilled water supply is available from
the central energy plant.


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 Reedy Creek solar energy system operated continuously throughout the
month of June. The DHW demand was 0.16 million Btu, there was no space
heating demand, and the space cooling demand was 18.78 million Btu. The
solar energy system supplied 100 percent of the DHW requirement, and 43
percent of the space cooling requirements these quantities are reported
in the attached computer printout as loads.








B. Weather


For June, the average outside ambient temperature measured at the site
was 82F. The long-term average temperature is 810F at the Orlando
weather station. The average measured insolation in the plane of the
array was only 1,826 Btu/ft2-day. This is very near the long-term
average of 1,830 Btu/ft2-day for June, which was derived from measure,
ments also taken at the Orlando weather station.


C. System Thermal Performance


Collector Of the 210.33 million Btu incident on the collector array,
21.17 million Btu were collected and delivered to the solar thermal
storage tank. This represents an array efficiency of 10.1 percent.
Operating energy of 1.19 million Btu (348 kwh) was required to collect
and store this solar energy.


Storage Of the 21.17 million Btu delivered to storage, 13.59 million Btu
were subsequently removed for use within the system. Temperature probes
within the solar thermal storage tank indicate that the internal energy
of the water increased by 0.43 million Btu during the month. This indi-
cates a resulting loss to the environment of 7.15 million Btu through the
tank insulation.


Domestic Hot Water DHW is provided to the building by passing city
water through a heat exchanger that is immersed in the solar thermal
storage tank. A total of 303 gallons of water at an average tempera-
ture of 134F was supplied by the system during June. The average
temperature increase was 640F, which resulted in a measured demand of
0.16 million Btu. All of this energy was supplied by the solar energy
system. There was no operating energy required.








a..: N "Lati. No S'dLe heating %as required during the month of June.


:.,-.'.- C..I L.r- The absorption chiller operated on 11 occasions to
r ,Ce t- chilled ,iter storage temperature during June. A total of 4.29
illir Btu of electrical energy fr-on the auxiliary conventional cooling
syst-- was re..ujired to assist the absorption chiller to meet the cooling
1.a on 23 days of the month. The absorption chiller utilized 13.43 mil-
iien Etu fr\:, the solar thermal storage tank to remove 7.36 million Btu
i.- t. chilled water storage (see attached Auxiliary Performance data).
The resultii.g coefficient of performance (COP) of 0.548 is very near the
average of the past 10 months.


Crill-:' Water S" rage Performance of the chilled water storage (see at-
. -:.'/ ,jxiliary Storage Perforrmnnce data) shows that 7.36 million Btu
were ier-:.ed by the chiller, 8.06 million Btu were added from the condi-
tieo. space during cooling, and the internal energy of the chilled water
storage increased by 0.31 million Btu. This implies that 0.40 million Btu
weVe lest by the water to the ambient environment through the insulation.


jDa:e .colir9 'pace cooling w'as required on all of the working days of
-. -.rth. The space cooling load was 18.78 million Btu. Water from the
chilled water storage was pumped through the air duct heat exchangers to
,e-ive 8.06 million Btu from the air. Chilled water from the central plant
was r-uire: to assist in supporting the cooling load during all but two
of t~- days of the month when space cooling was required. This resulted in
a s.ace cooling solar fraction of 43 percent for the month of June.


.-.ervations


The most significant anomaly observed during the month of June was the
drop in collector efficiency. Normal collector efficiency has averaged
near 14 ;trcerit, but during May it dropped to 12 percent, and in June it








was 10.1 percent. The loss In efficiency Is partially attributable to
an increase in cloud cover, which reduces the ratio of direct to total
solar radiation. Since these collectors primarily collect direct radia-
tion, this reduces their efficiency.


A collector tracking problem has recently been discovered which also
significantly affects collector efficiency. This problem of the col-
lectors mistracking the sun resulted in collection beginning almost an
hour later in June than in April, and generally continuing for an hour
longer in June than in April. Apparently the mistracking began to occur
in May. It should be corrected during July.


Losses from both storage tanks were below their typical levels, which
have generally been higher than expected for their design. It is expected
that there will always be a significant variance in the calculated values
of tank losses. This uncertainty arises from the fact that this calculation
involves the measurement of small changes in storage temperature, which may
be biased by thermal stratification within the tank, fluctuations in temper-
atures during the course of the 24-hour period over which it is averaged,
and small sensor inaccuracies.


Investigations are being made in an attempt to determine the accuracy of
several temperature sensors, and to improve them if possible.


E. Energy Savings


A total electrical energy savings of 0.36 million Btu (107 kwh) was
realized. This value assumes that, had there not been a solar energy
system, the energy requirements would have been met by an electrical
hot water heater and by a conventional electrical heat pump.

III. ACTION STATUS


The accuracy of the several temperature sensors in the space cooling
system are being investigated.
