REEDY CREEK UTILITIES
MAY 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 schematically in Figure 1, has five modes of solar
operation.


Mode 1 Collector-to-Storaqe: This mode is entered when the collector
absorber plate temperature is 10F higher than the temperature at the
bottom 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 Domestic Hot 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 the 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 the wdter going to the generator exceeds the upper limit of 1950F,
the water is tempered with cooler water returning through valve V4.


Mode 5 Space Cool'iAg: The space cooling mode is initiated when the
building te,ioerature exceed- th-e setting of the conditioned space
thermostat. Chilled water from the chilled water storage is then
circulated by pump P6 to the heat exchangers in the building air distribu-
tion 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. PEFFORMANCE EVAL'.'TI:'i


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. Intro:iuction


The Reely Cre-i solar crergy system operated continuously throughout the
month of May. The DHW demnad --cas 0.19 million Btu, there was no space
heatir e,-iiind, and the space cooling demand was 14.02 million Btu. The
solar t',ir-'.s system supplied 100 percent of the DHW requirement, and 58
percent of t;-. sp, ,c.e cooling requirements these quantities are reported
in the attac!e d'.1 computFr printout as loads.






B. Weather


For May, the average outside ambient temperature measured at the site
was 770F. The long-term average temperature is also 770F at the Orlando
weather station. The average measured insolation in the plane of the
array was only 1,722 Btu/ft2-day. This is considerably less than the
long-term average of 1,988 Btu/ft2-day for May, which was derived from
measurements also taken at the Orlando weather station.


C. System Thermal Performance


Collector Of the 204.95 million Btu incident on the collector array,
25.39 million Btu were collected and delivered to the solar thermal
storage tank. This represents an array efficiency of 12.4 percent.
Operating energy of 1.35 million Btu (396 kwh) was required to collect
and store this solar energy.


Storage Of the 25.39 million Btu delivered to storage, 17.79 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 0.37 million Btu during the m.r th. This indi-
cates a resulting loss to the environment of 7.23 million Btu through the
tank insulation. A further discussion of the '!.nk insulation heat trans-
fer is contained in Section II-D, Obhervation ,.


Domestic Hot Water Domestic hot water is provi,!d to the building by
passing city water through a heat exchanger that is imme ->rd in the
solar thermal storage tank. A total of 376 gallon.' cf *a'dter at c,
average temperature of 1280F were supplied by this system dur I,-. ',ay,
The average temperature increase wa6' 58F, -'hici *=..ulted in a iec aured
demand of 0.19 million Btu. All of this _re-r./- wIs ',i.* y by the
solar energy system. There was n;:. ce-':ti .' ..c *i ;.







Space Heating No space heating was required during the month of May.

Absorption Chiller The absorption chiller operated on 14 occasions to
reduce the chilled water storage temperature during May. A total of 2.35
million Btu of electrical energy from the auxiliary conventional cooling
system was required to assist the absorption chiller to meet the cooling
load on 20 days of the month. The absorption chiller utilized 17.60 mil-
lion Btu from the solar thermal storage tank to remove 7.21 million Btu
fro,- the chilled water storage (see attached Auxiliary Performance data).
The resulting coefficient of performance (COP) of 0.504 is slightly less
than that experienced last month, but very near the average of the past
10 months.


Chilled Water Storage Performance of the chilled water storage (see at-
tached Auxiliary Storage Performance data) shows that 7.21 million Btu
., removed by the chiller, 8.15 million Btu were added from the condi-
tioned space during cooling, and the internal energy of the chilled water
storage decreased by 0.36 million Btu. This implies that 1.27 million Btu
.^re lost from the water to the ambient environment through the insulation.


Space Cooling Space cooling was required on all of the working days of
the month. The space cooling load was 14.02 million Btu. Water from the
chilled water storage was pumped through the air duct heat exchangers to
remove 8.15 million Btu from the air. Chilled water from the central plant
was required to assist in supporting the cooling load during all but three
of the days of the month when space cooling was required. This resulted in
a space cooling solar fraction of 58 percent for the month of May.


D. Observations


Thf absorption chiller COP was slightly down from the exceptionally high
valuee e-:prienced in April. This can be attributable to the more typical
insolatirn experienced in May. The sky was exceptionally clean in April,







resulting in more direct and less diffuse solar energy. The collectors
at Reedy Creek primarily collect direct solar radiation and, therefore,
were able to supply the absorption chiller with higher temperature water
in April. Cloud cover increased in May to a more typical level, and this
in turn, slightly reduced the generator inlet temperature of the absorp-
tion chiller, which slightly reduced the COP. It should be noted that
the average daily temperatures shown in the tables will not necessarily
indicate the decreased temperature when averaged over a 24-hour period.
This is because the chillers can rapidly lower the storage tank tempera-
ture when it is operated.


Losses from the hot water storage tank were less than the previous month
but similar to what has been observed over the past eight months. This
rate of loss of thermal energy appears to be large when compared to other
solar energy systems, but typical for the Reedy Creek Facility.


Instrumentation indicates a loss of 1.27 million Btu to the environment
from the chilled water storage tank. This occurred while the average
tank temperature was below the ambient temperature. This phenomenon
cannot actually occur, but has been indicated on several occasions in
the past. It is most likely due to thermal stratification within the
tank and to small temperature changes which are less than the accuracy
of the instrumentation. Investigations will be trade in an attempt to
determine the accuracy of several temperature se;,ors, to improve them
if possible.


E. Energy Savings


A total electrical energy savings of 0.37 million Btu (108 kwh) was
realized. This value assumes that, had there not been a solar energy
system, the energy requirements would have beer met by an electrical
hot water heater and by a conventionril electrical heat pump.







III. ACTION STATUS


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