MONTHLY PERFORMANCE REPORT
LUTZ-SOTIRE
FEBRUARY 1979


I. SYSTEM DESCRIPTION

The Lutz-Sotire solar energy system serves a three-story, 25,000-square
foot office building located in Stamford, Connecticut. This retrofit
system supplies energy to a distributed heat pump system consisting of
64 water-to-air heat pump units connected in a closed hydronic loop.
The solar collector array contains 2,561 square feet of collector area
consisting of 138 flat-plate collectors augmented by 2,927 square feet
of reflectors. The collectors are tilted at 55 degrees, the reflectors
at 10 degrees from the horizontal. A 50 percent ethylene glycol solution
is used as the energy collection and transport fluid. Solar energy is
stored in water contained in a 6,000-gallon storage tank partially buried
beneath the parking lot. "From the storage tank, solar heated water is
distributed to the building's heat pump loop. The existing electrical hot
water boiler provides auxiliary energy.

Because the solar energy system supplies its energy to the heat pump hy-
dronic loop, the terminology normally used in the National Solar Heating
and Cooling Demonstration must be modified. Heating load normally applies
to energy added to the air of the conditioned space; however, in this sys-
tem, it will be understood to refer to the energy demand on the equipment
supplying energy to the heat pump hydronic loop. This energy is the sum
of the solar and auxiliary energy extracted from those subsystem reservoirs
and whatever energy may be added to the hydronic loop by individual heat
pumps extracting heat from the conditioned space and placing it in the hy-
dronic loop (cooling mode).


The Lutz-Sotire solar energy system, shown schematically in Figure 1, has
the following modes of operation:











































Figure 1. LUTZ-SOTIRE SOLAR ENERGY SYSTEM SCHEMATIC









Mode 1 Collector-to-Storage: This mode is initiated whenever the col-
lector plate temperature is approximately 20F above the solar tank tem-
perature. This mode is exited when this temperature differential drops
below 5*F.

Mode 2 Storage-to-Space Heating: This mode is initiated whenever the
supply temperature of the closed cycle hydronic loop falls below 800F
and the temperature of the solar storage tank is above 750F. Solar
heated water is fed into the hydronic loop until its temperature rises
to 800F or until the temperature of the solar storage tank falls below
750F.


Mode 3 Auxiliary Heating: This mode is activated whenever the supply
temperature of the closed cycle hydronic loop falls below 750F. Water
heated by the existing electrical boilers will be fed into the hydronic
loop until the supply temperature rises to 750F.


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


The Lutz-Sotire solar energy system was operational throughout the month
of February. It supplied 28.6 million Btu of energy to the hydronic loop
serving the several heat pumps whose total demand was 83.1 million Btu.
This represented 42 percent of the total energy supplied to the heat pump
array and an estimated 23 percent of the space heating load.









Direct measurement of both the solar and auxiliary energy contributions
to the hydronic loop are precluded by instrumentation problems. Estima-
tions of these parameters based upon other measured data have been sub-
stituted for the missing measured data which has been nulled from the
individual subsystem reports.

B. Weather


The average ambient temperature for the month was 200F. This is compared
with 340F for a long-term average taken at the Bridgeport, Connecticut,
weather station 30 miles to the north. The average insolation in the plane
of the collector array was 1,317 Btu/ft2-day as compared with 1,058 Btu/ft2-da
long-term average. This long-term prediction was obtained from the New York
weather station 30 miles to the south.


C. System Thermal Performance


Collector Of the 94.4 million Btu incident upon the collector array during
the month, 35.0 million Btu were collected. This represents a collector ar-
ray efficiency of 37 percent. Operating energy of 2.8 million Btu (833 kwh)
was required to collect and store this energy.


Storage From the 35.0 million Btu collected, 33.5 million Btu were de-
livered to storage. Nearly constant daily usage of the energy from this
tank kept the average temperature at 840F. Because of an instrumentation
incompatibility, energy removed from storage as normally tabulated on the
Storage Performance Report has been nulled and a better estimate is obtained
assuming the uncontrolled losses are 10 percent of the input energy and using
the equation:

STEI = STEO + STECH + STLOSS









Solving for STEO


STEO = STEI STECH STLOSS
= STEI TECH (0.1 X STEI)
= 33.5 1.6 3.3
= 28.6 million Btu


Space Heating Space heating at the Lutz-Sotire site is accomplished by
64 individual heat pumps which use as their source a hydronic loop whose
temperature is maintained by solar and auxiliary sources. There is no di-
rect contribution to the space heating load by solar energy. A tabulation
of the energy removed from the hydronic loop by the heat pumps has been
listed under the heading Space Heating Load on the Space Heating Subsystem
report. This demand has resulted in a measured 83.1 million Btu being re-
moved from the hydronic loop. A further discussion of this quantity is
contained in Section D, Observations.

D. Observations


Using a technique developed in the December (Narrative) report on this
site, a comparison figure for the hydronic loop demand as measured may
be calculated. It should be noted that the total energy extracted from
the hydronic loop should not be greater than the total energy collected
plus the auxiliary electrical energy demand, for there are known uncon-
trolled losses to the environment. The energy removed from storage has
already been calculated as 28.6 million Bcu. It will be assumed that
all of this energy was inserted into the hydronic loop.

Because the temperature of the auxiliary storage tank is known to be main-
tained at a higher temperature than the solar tank, the losses will be as-
sumed to be 20 percent of the total energy supplied. All of the remaining
energy consumed by the electric boiler will be assumed to have been supplied
to the hydronic loop. As may be seen on the Space Heating Subsystem report,
the total auxiliary energy consumed was 49.4 million Btu. It will be assumed
that 80 percent of this energy or 39.5 million Btu was actually inserted into
the hydronic loop.









It may be seen that the sum of the solar and auxiliary energy added to the
hydronic loop is 68.1 million Btu. This figure is substantially below the
measured demand of 83.1 million Btu. No explanation of this occurrence is
presently available. An instrumentation subsystem study is continuing to
evaluate the entire philosophy of instrumenting sites of this type and this
site in particular.


It is believed that the total energy input to the hydronic loop is more
nearly approximated by the sum of the auxiliary and solar energy contri-
butions (modified for losses) than is the direct measurement at the load.
Under this assumption, the solar fraction of the load can be calculated as


solar energy
SFR =
solar energy + auxiliary energy + heat pump electrical energy

28.6
= -= 23 percent.
28.6 + 39.5 + 55.4


E. Energy Savings


Based on the assumptions and calculation shown above, a total of 25.8 mil-
lion Btu of electrical energy savings was realized. This value assumes that
had there been no solar energy system, all energy supplied to the hydronic
loop would have come from the auxiliary source.


III. ACTION STATUS


A thorough reevaluation of the instrumentation subsystem at the site is in
progress. Under consideration are:


(1) Increasing the existing voltage to all flowmeters and electrically
converting them to totalizing meters, thus reducing threshold sen-
sitivity to 5-7 gpm.









(2) Investigating and recalibrating where necessary all temperature
sensors involved in the heat pump hydronic loop energy balance
calculations.
