MONTHLY PERFORMANCE REPORT
COLUMBIA GAS SYSTEM
JUNE 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.









Mode 2 Collectors Stowed: While in Mode 2, the collector reflectors are
turned downward toward the roof, or stowed, to prevent collector damage from
excessive heat or the elements. This mode is entered from Mode 1 by a two-
step process:


1) While in Mode 1, if one or more of five conditions is met, the
collectors are placed in the stowed position. These five condi-
tions are: a. wind speed greater than 30 mph for approximately
10 seconds; b. measured insolation in the principal plane of the
collector less than approximately 150 Btu/ft2-hr; c. differential
pressure switch senses no flow in the collector loop; d. collector
array outlet temperature greater than 2520F; and e. storage tank
temperature greater than 2200F.


2) When the collectors have returned to the stowed position, storage"
loop pump P10 is turned off, the primary side of the collector
loop heat exchanger is bypassed, and collector loop pump P11 is
turned off.


If the collectors were stowed due to an absence of collector loop flow, manual
reset is required before Mode 1 can be reentered. However, if the collectors
were stowed for any of the other four conditions, Mode 1 will be reentered
automatically whenever its entry conditions are met.


Mode 3 Collector Emergency Stow: This mode is used to stow the collectors
in the event of a power failure. This mode is entered from Mode 1 by a four-
step process:


1) If voltage-sensitive relays in all tracking motor phases detect
that any phase has dropped below 70 percent rated voltage, an
emergency generator is activated.


2) When the generator has reached operating voltage, transfer switches
autor;tically transfer the control system and collector loop pump
P11 from the normal building power to the emergency generator.








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.








While in this mode, solar energy is routed directly from the collectors to
storage via the collector loop heat exchanger. Mode 5 is terminated upon
entry to Mode 2, 3 or 4.


Mode 6 Storage-to-Domestic Hot Water: This mode occurs while a domestic
hot water demand is present. When hot water is being used, makeup cold
water flows by supply pressure through the hot water preheat coil- in the
storage tank. This makeup water absorbs stored solar energy as it passes
enroute to the conventional hot water heater.


In addition to these six modes, individual collector rows can be stowed if
they overheat. Each of the 11 individual collector rows has a separate con-
trol system sensor indicating absorber tube temperature. If the temperature
of an individual collector row absorber tube exceeds 2600F, that collector
row is stowed. When the temperature then drops below 2200F, that collector
row resumes tracking. If the collector row overheats a second time, a manual
reset is required to restart the individual collector row.


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


Tr. solar energy system at the Columbia Gas site collected energy on 23
*!ays duriru June and supplied 3.0 percent of the total system thermal
ener.-y load. Space heating, space cooling, and domestic hot water heat-
ing received 7.3 million Btu of solar energy during the month. Although
a'.-rage storage 't:-iperatures exceeded the 1500F control set point for









heating on 27 days during the month, little solar energy was used for space
heating due to the master controller being set for summer operation, which
has a 1900F set point. Space heating was required on 28 days. Space cooling
was required each day of the month.


B. Weather


The long-term average outside ambient temperature for Columbus in June is
700F. Also, Columbus has a long-term average of 13 heating degree-days,
and 175 cooling degree-days in June. This month the actual outside ambient
temperature average was 720F. There were three heating degree-days and 197
cooling degree-days. The measured insolation in the plane of the pyranome-
ters (five degrees east of south, with a tilt of 40 degrees from the horizon-
tal) averaged 1,583 Btu/ft2-day, which is less than the expected long-term
average of 1,814 Btu/ft2-day. This reduction in available solar energy was
responsible for some decrease in solar energy system performance.


C. System Thermal Performance


Collector Of the 141.4 million Btu of incident solar energy on the col-
lector array during June, 58.7 million Btu were incident on the array while
collection and storage pumps P11 and P10 were operating. The system col-
lected 18.7 million Btu, or 13.2 percent of the total insolation incident
on the collector array. This was 22.5 percent of the insolation incident
while the pumps were operating. Since these collectors are tracking con-
centrators, 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, a total of 54.1 million Btu of direct solar energy was incident on the
collector array. Of this incident direct solar energy, 34.6 percent was
collected by the array, which agrees closely with the 37.0 percent collec-
ted in May. During June, pumps P10 and P11 and the collector tracking
motors used a combined total of 1.6 million Btu of electrical energy.









StoragL Of the 18.73 million Btu of solar energy collected, 14.82 mil-
lion Btu were delivered to the storage tank. A total of 3.13 million Btu
of solar energy was extracted from the storage tank. A total of 2.03
million Btu of solar energy was extracted from the storage tank to pre-
hat domestic hot water. The net energy in storage decreased by 0.30
million Btu during the month. A summary of energy in and out of storage
is shown below. The net thermal loss from storage was 11.99 million Btu.


14.82 million Btu energy to storage tank
3.13 million Btu energy extracted from storage tank
11.69 million Btu
0.30 million Btu energy decrease in storage tank
11.99 million Btu thermal loss from storage tank


Ccmestic Hot Water Load The domestic hot water subsystem operated con-
tinuously during June. The daily average hot water consumption was 141
gallons for the month. The 2.17 million Btu of energy added to the sub-
system were comprised of 2.03 million Btu of solar energy and 0.14 million
Btu of auxiliary thermal energy, giving a hot water solar fraction of 93
percent. Hot water was supplied at an average temperature of 1200F and
was replaced with cold water at an average temperature of 710F.


Space Heating Load Space heating was required on 28 days during June.
The space heating load of 29.1 million Btu was supplied by 28.7 million
Btu of auxiliary thermal energy and 0.4 million Btu of solar energy. In
order to provide the auxiliary thermal energy, 64.4 million Btu of
natural gas were required. The ratio of auxiliary thermal energy used to
natural gas supplied showed a boiler conversion efficiency of 44.6 percent.
As previously mentioned, storage temperatures must exceed 1500F before
solar energy can be used for space heating. Although average storage
t, -/--ratures exceirJed 1500F on 27 days during June, the space heating re-
,:,i, ,i-,nts were largely provided from the boiler due to a 1900F requirement
for water tt-riLerature for the absorption chiller.








Space Cooling Load The absorption chiller required 301.4 million Btu to
provide 124.8 million Btu of chilled water. Solar energy supplied 5.6
million Btu and the auxiliary boiler supplied 295.7 million Btu to the
absorption chiller. In order for solar energy to be used for space cool-
ing, the temperature 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
five days. Total elapsed time for the five days was approximately two
hours. Calculations indicated 458.0 million Btu of natural gas were required
to provide auxiliary thermal energy. The coefficient of performance of the
absorption chiller was 0.41. The total space cooling load in June was
124.8 million Btu.


D. Observations


The solar energy system supplied three percent of the system thermal
energy requirement. For the previous six months of system operation, the
net measured solar contribution was between 0.66 and 5.0 percent, which
contrasts to an expected solar contribution of 30 percent. The decrease in
solar contribution from five percent for May to three percent for June can
be partially attributed to a decrease in operational time for the solar
energy system. This was discussed with Philip Dechow of Columbia Gas
Corporation. If the set point of the pyranometer which energizes the
rotate mechanism for the collectors iq adjusted for the proper sun angle,
more operational time for the solar energy system would result.


A problem due to inadvertent flow of hot water through heating coils at the
wrong time is adding to the cooling load. For example, when the absorption
chiller was operating on June 9 as much as 900F temperature drop across the
T470 and T420 sensors was observed from 0000 to 2400 hours with no flow
indication on flowmeter W420. This is due to a backflow forced through
pumps P6, P7 and P8 and adds appreciably to the total building cooling
load. The actual added load is unknown. During the transitional season









this problem will not be easily solved. When cooling only is required, the
heating coils can be isolated with manual valves and the problem will be
el i:ni nated.


On July 10, 1979, the problem was discussed with Philip Dechow of Columbia
Gas Corporation. Evidently the same backflow problem occurred last year.
At that time existing check valves were removed, examined and reinstalled.
The reason they do not prevent this backflow is unknown. Philip plans to
close the manual valves around the heating coil and eliminate this problem
for the summer.


A system problem exists which interferes with utilization of stored solar
energy. For example, the space heating subsystem report shows that 28.7
million Btu of auxiliary thermal energy was used for space heating and 0.4
million Btu of solar energy was used for space heating; yet, the average
temperature of stored water exceeded 1500F on 27 days.


The stored solar energy was available for space heating but not used. This
appears to be due to "summer operation" which is manually selected by a
master controller (see Section I, Mode 4). The summer operation selection
causes solar energy flow from the storage tank to begin when the temper-
ature is greater than 1900F. The heating system could efficiently use
water with a temperature less than 1900F. Re-examination of the automatic
control system is suggested with a goal of increasing the percent of solar
energy utilized from the storage tank for space heating.


E. Energy Savings


The Columbia Gas solar energy system resulted in a savings of 12.08 million
Btu of natural gas during the month. In order to operate the solar energy
system, 1.58 million Btu of electrical energy were used to operate the col-
lector tracking motors and pumps. To allow a direct comparison of natural
-Ias savings with electrical expense, an efficiency of 30 percent was assumed
for converting natural gas to electricity and transmitting that energy to








the user. This shows that the 1.70 million Btu of electrical energy were
equivalent ot 5.27 million Btu of natural gas. Subtracting this from the
solar energy fossil fuel savings of 12.08 million Btu gave a net energy
savings of 6.81 million Btu of natural gas when compared to a conventional
system. Computed cumulative energy savings for October through June were
34.52 million Btu of equivalent fossil energy.


III. ACTION STATUS


The solar energy system collected energy on 23 days during June 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 con-
tribution. Site personnel are also checking the storage tank to determine
the source of high thermal losses.
