MONTHLY PERFORMANCE REPORT
IRVINE SCHOOL
JUNE 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 15F
(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 from 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 220F).
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
June except on the 20th. It satisfied 20 percent of the combined space
heating and cooling energy requirements. By design, the system performed
heating and cooling simultaneously for different areas of the building.
The space cooling requirements were 96 percent of the total system load.







B. Weather


Due to the year-round mild outside ambient temperatures in the Irvine School
area, simultaneous heating demand and cooling demand is not unusual. In
comparison to an expected average outside ambient temperature of 640F, the
actual outside ambient temperature averaged 720F during the month. The day-
time ambient temperature during the 9:00 a.m. to 3:00 p.m. hours averaged
84F. The measured insolation in the plane of the collectors averaged 1,886
Btu/ft2-day, below the expected long-term average of 2,002 Btu/ft2-day which
was derived from measurements taken at the Los Angeles International Airport,
California.


C. System Thermal Performance

Collector Of the 289.59 million Btu of solar energy incident on the collec-
tor array during June, 271.32 million Btu were incident on the collector array
when there was fluid circulating in the collector loop. The system collected
109.57 million Btu of solar energy, or 38 percent of the total incident insol-
ation on the collector array. In this solar energy system, collected energy
is either delivered to the load or rejected through the heat rejector. No
storage of energy is provided. During June, 21.25 million Btu of energy were
rejected by the heat rejector in the collector-to-load loop, resulting in a
net collection of 88.32 million Btu of energy. An additional 19.20 million
Btu of heat energy was rejected by the collector itself during the period of
low insolation.

Space Heating The outside ambient temperatures during June were low enough
to require some heating of the building during only 8 days of the month. The
resulting heating load was 6.55 million Btu. The heating subsystem utilized
0.80 million Btu of solar energy, and 6.48 million Btu of auxiliary energy.
The resulting solar fraction for space heating is 8.8 percent. The operating
energy of the space heating subsystem was 0.70 million Btu.

Space Cooling The space cooling subsystem was used every day in the month
of June. The space cooling load was 144.78 million Btu. There was 77.06








million Btu of solar energy used, and 400.15 million Btu of auxiliary energy
used for space cooling. The sum of the solar and auxiliary energies used
was 477.21 million Btu, which supported the space cooling load through
the absorption chillers. The resulting solar fraction for space cooling is
21 percent, and the operating energy of the space cooling subsystem during
June was 78.30 million Btu.


D. Observations


During June, 21.34 million Btu of auxiliary energy was delivered from the
load loop, through the heat exchanger, to the collector loop. This occurred
in both the early morning and late evening when both the auxiliary boiler
and solar collectors had their pumps on. During these same times, the col-
lectors lost 19.20 million Btu. In the month of June, the Irvine area ex-
perienced many warm days but temperatures dropped rapidly in the late
afternoon. Typically, nighttime temperatures range in the low to mid sixty's.
Once the solar insolation gets down to a low level in the afternoon, the col-
lectors become net rejectors of thermal energy and the collector loop becomes
a drain on the auxiliary system. This is, of course, just the opposite of
what the system was designed to perform.


The collectors have two sets of pumps; the main pumps and a smaller set whose
design purpose was to bring the collector tubes up to operating temperature
slowly to protect from thermal shock. These small pumps did not work as
planned. This aggravated the collector loss problem by not moderating the
flow rates during times of high loss. Collector and auxiliary systems typi-
cally come on by timer at 5:15 a.m. and go off at 8:00 p.m.


Analysis indicates that the collectors do not, as previously supposed,
contribute energy to the load side of the heat exchanger early in the
morning. When the auxiliary boiler is turned on before the collector
pumps, as was the case in June, the temperature of the water from the col-
lectors is too low, in comparison to the load side, for the heat exchanger
to pass energy in the collector to load direction.

_h







The heat loss problems through the collector do not indicate a poor design,
but they are a function o- the system controllers. The collectors are work-
ing relatively well when operated during periods of significant solar insola-
tion.

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. Considering the
climate of Orange County, buildings of this type generally require heating and
cooling during most months. The heating and cooling system at Irvine School
is designed to operate simultaneously when necessary. There are seven sepa-
rate zones in the building which are heated or cooled. The current 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 re-
fer 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.

It should be noted in passing that inside temperature consistently rose
during the night while the chillers were not operating. At the same time,
outside ambient temperature dropped into the 60 700F range, or even lower.
Like many buildings constructed during the same period as Irvine School, no
provision is made to take advantage of this source of natural cooling.

Irvine School has two very large capacity (100 ton) absorption chillers which
often experience low efficiencies when underloaded. In June the average daily
values of the Coefficient of Performance (COP) for the absorption chillers
ranged from a low of 0.16 to a high of 0.54. The average COP was 0.32. These
figures are much improved from the months before and are attributable to the
higher daytime temperatures.

An estimated value of 15 kw was used for power consumption of the pumps in
the cooling tower loop, since these pumps are uninstrumented.








E. Energy Savings

The Irvine School solar energy system resulted in a fossil fuel savings of
129.76 million Btu at an operating expense of 10.80 million Btu of electrical
energy. Converting the electrical energy to a fossil equivalent yields 36.00
million Btu of operating energy. Therefore, the net fossil savings was 93.76
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 requirements of the solar en-
ergy system.

III. ACTION STATUS


All sensors associated with the absorption chiller operation are being re-
calibrated to correct a small energy imbalance observed in its operation.
