MONTHLY PERFORMANCE REPORT
COLUMBIA GAS SYSTEM
APRIL 1979


I. SYSTEM DESCRIPTION


The Columbia Gas System site is a three-story, 25,000 square foot office
building in Columbus, Ohio. The solar energy system, which was added to
the existing building, is designed to provide 30 percent of the building's
total annual thermal energy requirements. The expected annual solar con-
tributions for the three subsystems are 32 percent for space heating,
23 percent for space cooling, and 70 percent for hot water. The collector
subsystem is comprised of 44 Honeywell, Inc. north/south tracking, con-
centrating collectors, facing five degrees east of south. The collectors
rotate about an approximate east/west axis to track the daily variation
in the sun's elevation angle, and direct the solar radiation toward the
absorber tube mounted above the reflectors. The collector array is
arranged in 11 rows with a total gross area of 2,978 square feet.


The collector loop heat transfer fluid is a 47 percent solution of Dowtherm
SR1. Collected solar energy is transferred to the loads, or to a 5,000-
gallon water thermal storage tank via a liquid-to-liquid heat exchanger.
Incoming city water is heated for use as domestic hot water on demand, by
passing it through another heat exchanger, or preheat coil, located within
the water thermal storage tank. A conventional 50-gallon gas-fired hot
water heater augments this solar hot water energy from the tank heat ex-
changer. Solar heated water is also used for space heating and cooling.
This thermal energy is supplied either to fin tube heating coils for space
heating, or to an absorption chiller for space cooling. When solar energy
is insufficient to satisfy heating or cooling demands, thermal energy is
provided by an auxiliary gas-fired boiler.


The solar energy system, shown schematically in Figure 1, has six modes of
operation which are defined as follows:

Mode 1 Collectors Tracking: In this mode, the collectors track the sun
to collect solar energy. This mode is entered by a four-step process:


1) If measured insolation in the principal plane of the collector
is greater than approximately 175 Btu/ft2-hr, storage tank tem-
perature is less than 2100F, wind speed is less than 20 mph, and
collector array outlet temperature is less than 2400F, then col-
lector loop pump P11 is turned on. At this time a closed valve
(not shown in Figure 1) allows collector loop flow to bypass the
primary side of the collector loop heat exchanger.


2) If flow is detected in the collector loop by a differential
pressure switch, the collectors are rotated to the correct
tracking position.


3) When the collectors have reached the tracking position, a dif-
ferential temperature controller checks the collector outlet
temperature to determine if it is at least 200F greater than
the storage temperature.


4) If this temperature differential is detected, storage loop pump
P10 is turned on to allow flow through the secondary side of the
heat exchanger, and the collector loop heat exchanger bypass
valve is opened to allow flow through the primary side of that
heat exchanger.


The collectors remain in Mode 1 until conditions are met for returning the
system to Mode 2 or Mode 3. While in Mode 1, if the collector outlet tem-
perature drops to less than 5F above the storage tank temperature, then
storage loop pump P10 is turned off and the collector loop bypass valve is
closed to bypass the primary side of the heat exchanger. The collectors
continue to track the sun and collector loop circulation is maintained un-
til the 200F temperature differential is again met, or until conditions for
return to Mode 2 or Mode 3 are met.








S2 to Stowed: while in Mode 2, the collector reflectors are
turr- ... :rd toward the roof, or stowed, to prevent collector damage from
exc sive heat or elements. This mode is entered from Mode 1 by a two-



1 ,ile in "od' 1, if :nre or more of five conditions is met, the
collectors are placed in the stowed position. These five condi-
ticrs are: a. wind sFeed greater than 30 mph for approximately
1C second-; b. -asured insolation in the principal plane of the
ol .tor less than approximately 150 Btu/ft2-hr; c. differential
r ssu,. switch sses no flow in the collector loop; d. collector
array outlet t-:F prature greater than 2520F; and e. storage tank
rature greater than 2200F.


Sn the collecto. have retL-ned to the stowed position, storage
p P10 is turre-' off, the primary side of the collector
Seat exc '-anger is bypassed, and collector loop pump P11 is
turn off.

3) The collector controls cause the collectors to move from the
tracking position to the stowed position in four stages (or
steps) using power from the emergency generator. During each
of the four stages, approximately one-fourth of the total col-
lector array will be stowed.


4) When all collectors have been stowed, the collector loop pump
is turned off. The controls are then reset for return to Mode 1
operation when building power is restored.


When building power has been restored, power transfer switches automatically
return to building power. After a 10-minute delay, the emergency generator
is turned off, and Mode 1 is reentered if its entry conditions are met.


Mode 4 Solar Energy-to-Space Heating/Cooling: This mode occurs when there
is a demand for space heating or cooling and the storage tank temperature
exceeds the minimum value suitable for the loads. If summer operation has
been manually selected by a master controller, this value is 1900F. If
winter operation has been selected, solar energy flow begins at 1500F.
These temperature settings are nominal values and can be adjusted by site
personnel if desired. When this control temperature setting has been ex-
ceeded, the boiler gas supply is immediately shut off and flow continues
through the boiler for two minutes to deplete some of the residual energy.
The load supply lines are then switched from auxiliary to solar energy.
When the storage temperature has dropped by 20F, Mode 4 is terminated. If
storage loop pump P10 is operating while Mode 4 is active, part of the energy
supplied to the loads will come directly from the heat exchanger and the
balance will come from storage. If this pump is not operating, all the solar
energy supplied to the loads originates from storage.


Mode 5 Collector-to-Storage: This mode occurs while the collectors are
operating in Mode 1, but the conditions for Mode 4 entry are not met.








, ile in this rldI, solar eneryg, is routed directly from the collectors to
storage via the collector loop heat exchanger. Mode 5 is terminated upon
entry to Mod, 2, 3 or 4.

St water demand is present. Wten hot water is being used, makeup cold

Srou.- to the con.entional hot water heater.


In additi.-r, to these six modes, individual collector rows can be stowed if
Sty overheat. Each of the 11 individual collector rows has a separate con-
t,-,r1 system s nsor indicating absorber tube temperature. If the temperature
of an irdivi al collector row absorber tube exceeds 2600F, that collector
row is stowed. ,:en the temperature then drops below 2200F, that collector
row r. -um-s tracking. If the collector row overheats a second time, a manual
reset is required to restart the individual collector row.


II. PERFCFP1ANCE EVALUATION


The system performance evaluations discussed in this section are based
primarily r., the analysis of the data presented in the attached computer-
:er;-rated -,-nthly report. This attached report consists of daily site thermal
and '-e,-:i values for each subsystem, plus environmental data. The performance
factors discussed in this report are based upon the definitions contained in
'SIR 76-1137, Tr-eral Data Requirements and Performance Evaluation Procedures
for the nationall Solar Heating and Cooling Demonstration Program.


A. Introduction


Tie solar energy system at the Columbia Gas site collected energy on
9 -.ys during April. This was due partially to relatively low insolation,
but was also affr. t~F- by the practice of operating the collector sub-
sster -ly on work ...ys. Consequently, solar energy supplied only








3.0 percent of the total system thermal energy load. Domestic hot water
was the only active solar energy load, and received 4.17 million Btu of
solar energy during the month. Although storage temperatures exceeded
the 1500F control set point for heating on several days during the month,
no solar energy was used for space heating or cooling. This was due
to manual intervention. High storage tank temperatures were maintained for
a few days during April by inhibiting circulation to the heating and cool-
ing loads. This was done to simplify analysis of storage thermal losses.


Measurement inaccuracies limited the extent of performance evaluation possible
for the domestic hot water subsystem.


B. Weather


April is typically a transitional month in Columbus, with a long-term average
outside ambient temperature of 54.30F and 418 heating-degree days. This
month the actual outside ambient temperature average was 510F and 422 heat-
ing-degree days were experienced. The measured insolation in the plane of
the pyranometers (five degrees east of south, with a tilt of 40 degrees from
the horizontal) averaged 1,123 Btu/ft2-day, which was significantly less
than the expected long-term average of 1,467 Btu/ft2-day. This reduction
in available solar energy was responsible for a decrease in solar energy
system performance.


C. System Thermal Performance


Collector Of the 100.3 million Btu of incident solar energy on the col-
lector array during April, 29.3 million Btu were incident on the array
while collection and storage pumps P11 and P10 were operating. The system
collected 9.67 million Btu, or 9.6 percent of the total insolation incident
on the collector array. This was 33.0 percent of the insolation incident
while the pumps were operating. Since these collectors are tracking concen-
trators, they use only the direct or beam component of solar energy. While
pumps P10 and P11 were operating and the collectors were tracking the sun








J~.rirj ,,ril, a total of 25.5 million Btu of direct solar energy was inci-
dent cr the cLillec:tor array. Of this incident direct solar energy, 37.9
.-rLcert .,Is collected by the array, which agrees closely with the 35.1 per-
crt collected in March. During April, pumps PO1 and P11 and the collector
tracking motors used a combined total of 0.57 million Btu of electrical
energy.


"t :,_ Of the 9.67 million Btu of solar energy collected, 8.59 million
Btu .. re i-elivered to the storage tank. Since all collected solar energy
during -',ril was routed directly to the storage tank and none was used
dir.-.tly by t'e heating and cooling loads, the energy to storage could be
I:-Jucted fr:r the collected solar energy to determine a loss of 1.08 million
Btu between the collector array and storage. This loss was 11.2 percent
.'d was ,.,e to heat exchanger inefficiency and line losses. A total
of 4.17 million Btu of solar energy was extracted from the storage tank to
pre'-~at d,-,i,-,-tic hot water. The net energy in storage increased by 1.03
million Btu during the month. A summary of energy in and out of storage
is s' .,wn below. The 'I,-t thermal loss from storage was 3.39 million Btu.

S-- tic Hot 'iter Load The domestic hot water subsystem operated con-
tinuously d. i- Aprill The daily average hot water consumption was 300
11 for 'he n' The 6.52 million Btu of energy added to the subsystem
c -rised f 4.17 million Btu of solar energy and 1.85 million Btu of
ax' other ierr giving a hot water solar fraction of 77 percent.
vt aer was s i :' at an average temperature of 1160F and was replaced
,t-- co d water t a average te- v rature of 590F.








Space Heating Load Because of the relatively cool ambient temperatures,
space heating was required each day during April. The space heating load
of 148.7 million Btu was supplied solely by auxiliary thermal energy. In
order to provide this auxiliary thermal energy, 239.5 million Btu of natural
gas were required. The ratio of auxiliary thermal energy used to natural
gas supplied showed a boiler conversion efficiency of 62.1 percent. As
previously mentioned, storage temperatures must exceed 1500F before solar
energy can be used for space heating. Although storage temperatures ex-
ceeded 1500F on several days during April, the space heating loop was
manually isolated from the solar energy system and no solar energy was used
for space heating.


Space Cooling Load No solar energy was used for space cooling during the
month. In order for solar energy to be used for space cooling, the tem-
perature in the top of the storage tank must be greater than or equal to
1900F to run the absorption chiller. If this temperature is reached, solar
energy for space cooling can be supplied directly from the collector array
via the heat exchanger, from storage, or from a combination of both. During
this month, the top storage temperature exceeded 1900F on April 19 and 20.
Total elapsed time for both days was approximately two hours. Auxiliary
thermal energy was used to provide 39.6 million Btu of space cooling during
the month. The absorption chiller used 88.9 million Btu of auxiliary thermal
energy. Calculations indicated 130.5 million Btu of natural gas were re-
quired to provide this auxiliary thermal energy. The coefficient of per-
formance of the absorption chiller was 0.45.


D. Observations


The solar energy system showed a noticeable improvement in performance in
April, by supplying three percent of the system thermal energy requirement.
This is primarily due to a more accurate flow totalizer recently installed
in the domestic hot water subsystem. For the previous six months of system
operation, the net measure solar contribution was between 0.66 and 1.22
percent, which contrasts to an expected solar contribution of 30 percent.
Additional activity is in progress at the site to decrease thermal losses
from storage and reduce collector array tracking limitations. As this
effort continues, a gradual increase in system performance is anticipated.








r, nt.ed in Section A, solar energy was collected on only nine days during
April. "re collection subsystem was not enabled on nine other days during
the -'.r- whi"- fell cr weekends. This left 12 days during the month when
t'>- subsystem :,s enabled but did not collect energy. Further examination
of the data shikoed that available insolation in the principal plane of the
collector was not sufficient to activate collection on 11 of these 12 days.
C. ti.. '-_ inningg one day (April 24), available insolation exceeded 175
Btu/ft -hour for 1.5 hours but the pumps and tracking motors were not
tL,' r. This irdicates that either the wind speed exceeded 20 mph on
e.r:h of these d.cys, or the collection loop was disabled.


A pr-._l', du.. to iradvertent flow of hot water through heating coils
at t-- w-r', ti"e is adding to the cooling load. For example, when the
abso :ticr chiller was operating on April 25 as much as 700F temperature
drcp across t-,- T470 and T420 sensors was observed at17:57 hours with ro
-". r_'i,_'.tion r fl:-,.n:iter W420. This is due to a backflow forced
tn,,rl,. u pumps P6, P7 and P8 and adds appreciably to the total building
c.olir load. The actual added load is unknown. During the transitional
season this pr--blem '1ll not be easily solved. When cooling only is
r-.-uir.--, the heating coils can be isolated with manual valves and the
S1.- will t eliminated.





,e ..rb"a .g.s s.lar energy systerrm resulted in a savings of 6.94 million
Btu of r-.tral J. ring the month. This savings is the natural gas
- .uivalet Uf 4" 4.17 million Btu of solar energy removed from storage and
S' estic :t water. This savings resulted only fc:r the
.' tic rct water load because no solar energy was used for either heating

Si c, .:aris.r of natural ,js savings with electrical exFense,
... ,.* ent was aS'_ssurL for converting natural cas to elec-
(t r ittinr tat energy to the ustr. This shows that the 0.57
r it t el icl er:i .,',. equivalent to 1.88 million Btu of








natural gas. Subtracting this from the solar energy fossil fuel savings of
6.94 million Btu gave a net energy savings of 5.05 million Btu of natural
gas when compared to a conventional system. Computed cumulative energy
savings for October through April were 7.54 million Btu of equivalent
fossil energy. However, actual savings may be as much as twice this amount,
due to measurement uncertainties in the hot water subsystem.


III. ACTION STATUS


The solar energy system collected energy on nine days during April and is
still being refined by site personnel. As this activity continues, the
solar energy system will become fully operational and carry a larger por-
tion of the system load. Collector array modifications are in progress to
improve tracking accuracy, which will increase the solar energy contribution.
Site personnel are also checking the storage tank to determine the source
of the high thermal losses. A maintenance visit is planned for May 1 to
make adjustments to the hot water instrumentation.
