MONTHLY PERFORMANCE REPORT
IRVINE SCHOOL
MARCH 1979


I. SYSTEM DESCRIPTION


The El Camino Real Elementary School, referred to hereafter as Irvine
School, is located in Central Orange County, California. The school is
approximately ten miles from the Pacific Ocean, and was built in 1971.
The building contains 41,109 square feet of floor area, and is normally
occupied five days a week by 850 children and 60 adults. Building oc-
cupancy is uniform throughout the year since the school operates on a
trimester plan. The solar energy system was added to the existing
building, and was designed to supply 50 percent of the annual building
heating and cooling demand.


The solar energy installation includes 4,950 square feet of evacuated
tubular glass collectors, a heat rejector, and a heat exchanger from the
collector loop to the load loop. The collector array faces south at an
angle of 25 degrees from the horizontal. Water is used as the medium
for delivering solar energy from the collector array to the heat ex-
changer for transfer to the load subsystems. Existing load loop components
were unaltered except for controls. These load loop components include
a 4 million Btu per hour boiler, two 100-ton absorption chillers, 41 heat-
ing coils, and seven air handlers. Since heating demands are low due to
the moderate climate and most of the load demand occurs during the day,
no solar energy storage is provided. The collected solar energy is trans-
ferred directly from the collector loop to the load loop via the heat
exchanger. If collected energy exceeds the load loop demand, excess
energy is rejected via the heat rejector. The heat rejector is a water-
to-air heat exchanger mounted on the roof and situated in the collector
loop between the collector outlet and the load loop heat exchanger inlet.
If the solar energy does not meet the full energy demand from the loads,
the boiler is activated to make up the shortage before the hot water








reaches the loads. The hot water is routed to the chillers or heating
coils, or both, depending on the building demand. The hot water then
returns to the heat exchanger to complete the cycle.

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


Mode 1 Collector Protection: This mode occurs when the lower flow
capacity (15 GPM) auxiliary collector pumps are turned on by a clock
timer. This is normally before collection begins and is required to pre-
condition the collectors for main pump flow and ambient temperature con-
ditions. This mode is reentered daily at the completion of mode 2
operation, and is subsequently terminated by the clock timer. Since no
other freeze protection subsystem is provided, this mode is also entered
when the outside ambient temperature is less than 380F. The clock con-
troller is overridden for freeze protection entry when this control temp-
erature has been reached.


Mode 2 Solar Energy Collection: This mode occurs when the main collec-
tor pump (125 GPM) is on. Mode entry requires a differential temperature
of 150F between the collector outlet and the load side inlet to the heat
exchanger. When the differential temperature again drops below 150F
(adjustable), mode 1 is reentered.

Mode 3 Collector-to-Space Heating/Cooling: In this mode, heating and
cooling loads may be active at the same time. This mode is enabled at
all times, and receives energy from the solar energy system when avail-
able. If solar energy is not available, or is insufficient to satisfy
the full demand, the auxiliary boiler is activated to supply the remain-
ing demand. At night, this mode is normally disabled by the clock timer.


Mode 4 Solar Heat Rejection: This mode occurs when excess solar energy
is diverted 'rom the collector loop and rejected to the environment

through a liquid-to-air heat exchanger on the roof. This mode is entered
if the temperature at the collector loop outlet from the heat exchanger
exceeds a variable set point (approximately 2150F). Upon exceeding this
set point temperature, a three-way valve is switched to initiate collector
loop flow through the heat rejector, and the heat rejector fan is turned
on to increase the air flow across its coils. When the heat exchanger
outlet temperature drops below another variable set point (approximately
2000F), the three-way valve is reversed, the heat rejector fan is turned
off, and this mode is terminated.

Mode 5 Collector Backup Protection: This mode is entered when the col-
lector outlet temperature exceeds a set point (approximately 2200F).
Control design assumes the collector pumps are not operating if this tem-
perature is exceeded. In this mode, normally open solenoid valves allow
city supply water to enter the collectors and drain out at the collector
outlet. This mode protects against collector thermal shock damage if a
power outage occurs.

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 def-
initions contained in NBSIR-76-1137, Thermal Data Requirements and Per-
formance Evaluation Procedures for the National Solar Heating and Cooling
Demonstration Program.


A. Introduction

The solar energy system at Irvine School operated continuously during
March, and satisfied 23 percent of the combined space heating and cool-
ing energy requirements. By design, the system performed heating and
cooling simultaneously for different areas of the building. The space
cooling requirements were 63 percent of the total system load.







B. Weather


Due to the year-round mild outside ambient temperatures in the Irvine School
area, only a relatively small heating load, or cooling load, is expected.
In comparison to an expected outside ambient temperature of 550F, the actual
outside ambient temperature averaged 590F during the month. The measured
insolation in the plane of the collectors averaged 1,651 Btu/ft2-day, which
is below the expected long-term average of 1,972 Btu/ft2-day which was
derived from measurements taken at the Los Angeles International Airport,
California.


C. System Thermal Performance


Collector Of the 253.28 million Btu of solar energy incident on the
collector array during March, 245.15 million Btu were incident on the col-
lector array when there was fluid circulating in the collector loop. The
system collected 102.76 million Btu of solar energy, or 41 percent of the
total incident insolation on the collector array. In this solar energy
system, collected energy is either rejected through the heat rejector or
delivered to the load. No storage of energy is provided. During March,
19.50 million Btu of energy were rejected by the heat rejector in the col-
lector-to-load loop, resulting in a net collection of 83.26 million Btu of
energy.


Space Heating The outside ambient temperatures during March were low
enough to require heating of the building almost every day. The resulting
heating load was 39.66 million Btu. The heating subsystem utilized 5.13
million Btu of solar energy, and 42.40 million Btu of auxiliary energy. The
resulting solar fraction for space heating is 13 percent. The operating
expense of the space heating subsystem was 4.29 million Btu.


Space Cooling The space cooling subsystem was used every day in the month
of March. The space cooling load was 68.40 million Btu. There were 72.71
million Btu of solar energy used, and 219.40 million Btu of auxiliary
energy used for space cooling. The sum of the solar and auxiliary energies









used was 292.11 million Btu, which supported the space cooling load through
the absorption chillers. The resulting solar fraction for space cooling is
29 percent, and the operating energy of the space cooling subsystem during
March was 79.20 million Btu.


D. Observations


During March, 23.94 million Btu of auxiliary energy were delivered to
the collector array. This occurred early in the mornings, usually prior
to sunrise when the collector pumps were initially turned on, and there
was either a heating or cooling load, thus, providing flow through the
load-side of the heat exchanger. A calculated value of 3.57 million Btu
of energy was collected when no insolation was available. This phenomenon
is believed to be caused by the ability of the collector tubes to maintain
relatively high fluid temperatures overnight, thereby maintaining a positive
temperature change across the collector array; the collector pumps are
initially turned on between 4:00 and 4:30 a.m. each day.

The calculated value of energy extracted from the boiler load-side of the
collector-to-load heat exchanger was 88.00 million Btu. This value is six
percent higher than the net solar energy collected. This energy imbalance
is believed to be due to uncertainties in temperature measurement, and the
fact that some of the auxiliary energy delivered to the collectors is re-
turned as useful energy. The average flowrate through the heat exchanger
in the collector-to-boiler loop is relatively large at approximately
4,998 Ibs/min. Therefore, an energy imbalance can be observed due to a
small uncertainty in the temperature measurements T401 or T451. For ex-
ample, an 0.5 degree uncertainty in the temperature difference (T451-T401)
can result in an 8 million Btu error in the energy extracted from the heat
exchanger during the month. Therefore, any attempt to resolve energy
imbalances between energy collected, energy extracted from the heat ex-
changer, and the energy delivered to the load will be quite difficult,
since each temperature sensor has a rate accuracy of 0.250F. In an attempt
to only recognize valid measurements from the instrumentation, noise level








checks are performed on the output of the sensors. These checks are in-
tended to reject sensor noise and select only valid sensor data. However,
in an attempt not to set the constants used in the noise level test too
high, so as to reject valid data, occasionally a measurement will appear
acceptable even though it is only noise. These anomalies have very little
impact on the monthly performance factors since they generally occur only
in a few scans of data during the month.

Irvine School is a large building with few windows. It contains 41,109
square feet of floor area, and is normally occupied by 910 people. Con-
sidering the climate of Orange County, buildings of this type generally
require heating and cooling during winter months. The heating and cooling
system at Irvine School is designed to operate simultaneously when neces-
sary. There are seven separate zones in the building which are heated or
cooled. The current instrumentation philosophy does not permit thermal
analysis of each zone separately. Therefore, the data in the space heating
and space cooling subsections of the attached report refers to the combined
cooling or combined heating requirements for the entire school.

Similarly, the inside ambient air temperature defined in the space heating
and space cooling subsections of the attached report does not reflect the
average temperature for all zones, but represents the average inside ambient
air temperature in the area of the sensor.


The average daily values of the Coefficient of Performance (COP) for the
absorption chillers range from a low of 0.06 to 0.41. These values can be
misleading because frequently with absorption chillers operating, the tem-
perature drops across the cooling coils is less than one degree. The
air-handling units are uninstrumented, therefore, it has not been possible
to determine if the fans are on when W502 indicates flows and the tempera-
ture change between T552 and T502 is very small. With small temperature
changes, the instrumentation uncertainties can make the calculated value
of cooling load unreliable, and hence an unreliable COP.








An estimated value was used for power consumption of the pumps in the cool-
ing tower loop, since these pumps are uninstrumented.

E. Energy Savings


The Irvine School solar energy system resulted in a fossil fuel savings of
129.73 million Btu at an operating expense of 10.82 million Btu of electrical
energy. Converting the electrical energy to a fossil equivalent yields
36.07 million Btu of operating energy. Therefore, the net fossil savings
was 93.66 million Btu. The fossil energy savings calculations are based
on a comparison of the projected energy requirements of a conventional,
fossil energy boiler, with an efficiency of 60 percent, and the energy re-
quirements of the solar energy system.

III. ACTION STATUS


The Coefficient of Performance of the absorption chillers seems unreason-
ably low, and investigations are continuing to determine whether this is
due to system operation or some instrumentation anomaly.
