MONTECITO PINES

MARCH 1979

I. SYSTEM DESCRIPTION

The Montecito Pines site is an apartment complex in Santa Rosa, California.
It consists of one instrumented unit containing eight apartments. Each
apartment has approximately 864 square feet of conditioned space. Solar
energy is used for space heating and preheating domestic hot water (DHW). The
solar energy system which serves the 8-apartment unit has an array of flat-
plate collectors with a gross area of 950 square feet. The array faces 22
degrees west of south at an angle of 45 degrees to the horizontal. Water is
the transfer medium that delivers solar energy from the collector array to
storage and to the space heating and hot water loads. Freeze protection is
provided by drain down. Solar energy is stored underground in a 2000-gallon
insulated tank. City water is circulated through a heat exchanger in the
storage tank for preheating before'entering a gas-fired boiler which supplies
DHW on demand. When solar energy is insufficient to satisfy the space heating
load, the gas-fired boiler provides auxiliary energy for space heating. The
system, shown schematically in Figure 1, has four modes of solar operation.

Mode 1 Collector-to-Storage: This mode activates when the collector plate
temperature exceeds the storage temperature by 17F and terminates when a
temperature difference of 3F is reached. Collector loop pump Pl is operating.

Mode 2 Storage-to-Space Heating: This mode activates when there is a space
heating demand and the temperature at the top of the storage tank is 105F or
higher. Space heating pump P2 is operating and mode diversion valves Vl and
V2 divert the flow to the heat exchanger in the storage tank and bypass the
gas-fired boiler.

Mode 3 Auxiliary Space Heating, DHW Preheating: This mode activates when
there is a space heating demand and the temperature at the top of the storage
tank is less than 105F. Space heating pump P2 is operating and mode diversion
valves Vl and V2 direct the flow through the gas-fired boiler and bypass the
heat exchanger in the storage tank.

Mode 4 DHW Preheating: This mode activates when there is a demand for DHW.
Incoming city water passes through the heat exchanger in the storage tank on
the way to the gas-fired boiler which supplies hot water, on demand, to the
apartments.


II. PERFORMANCE EVALUATION


INTRODUCTION

The site was occupied during the month of March, and the solar energy system
operated continuously during the month. Solar energy satisfied 52 percent of

the DHW requirements and 11 percent of the space heating requirements. The
solar energy system provided fossil fuel energy savings of 13.1 million Btu at
an expense of 0.50 million Btu of electrical energy.


WEATHER CONDITIONS

During the month, total incident solar energy on the collector array was 34.3
million Btu for a daily average of 1163 Btu per square foot. This was below
the estimated average daily solar radiation for this geographical area during
March of 1669 Btu per square foot for a plane facing 22 degrees west of south
with a tilt of 45 degrees to the horizontal. The average ambient temperature
during March was 50F as compared with the long-term average for March of
53F. The number of heating degree-days for the month (based on a 65F ref-
erence) was 451, as compared with the long-term average of 381.


THERMAL PERFORMANCE

System During March the solar energy system performed slightly poorer than
expected. The expected performance resulted from a modified f-chart analysis
using measured weather and subsystem loads as inputs. Solar energy collected
was 10.0 million Btu versus an estimated 10.3 million Btu. Solar energy used
by the system was estimated by assuming that all energy collected would be
applied to the load. Actual solar energy used was 7.9 million Btu. System
total solar fraction was 22 percent versus an estimated 25 percent.

Collector The total incident solar radiation on the collector array for the
month of March was 34.3 million Btu. During the period the collector loop
was operating, the total insolation amounted to 28.9 million Btu. The total
collected solar energy for the month of March was 10.0 million Btu, result-
ing in a collector array efficiency of 29 percent, based on total incident
insolation. Solar energy delivered from the collector array to storage was
8.8 million Btu. Energy loss during transfer from the collector array to
storage was 1.2 million Btu. This loss represented 12 percent of the energy
collected. Operational energy required by the collector loop was 0.50 million
Btu.

Storage Solar energy delivered to storage was 8.8 million Btu. There were
8.3 million Btu delivered from storage to the DHW and space heating subsystems.
Energy loss from storage was 0.31 million Btu. This loss represented 4 percent
of the energy delivered to storage. The storage efficiency was 96 percent:
This is calculated as the ratio of the sum of the energy removed from storage
and the change in stored energy, to the energy delivered to storage. The
average storage temperature for the month was 99F.

DHW Load The DHW subsystem consumed 4.7 million Btu of solar energy and 5.5
million Btu of auxiliary thermal energy (equivalent to 6.8 million Btu of aux-
iliary fossil fuel energy) to satisfy a hot water load of 9.0 million Btu.
The solar fraction of this load was 52 percent. Losses from the DHW subsystem
were 1.2 million Btu. The DHW subsystem consumed a total of 0.70 million Btu
of operating energy. A daily average of 499 gallons of DHW were consumed
at an average temperature of 133F delivered from the tank.





Space Heating Load The space heating subsystem consumed 3.1 million Btu of
solar energy and 28.3 million Btu of auxiliary thermal energy (equivalent to
35.4 million Btu of auxiliary fossil fuel energy) to satisfy a space heating
load of 27.0 million Btu. The solar fraction of this load was 11 percent.
Losses from the space heating subsystem were 4.5 million Btu. The space
heating subsystem consumed a total of 2.2 million Btu of operating energy.

OBSERVATIONS

Sensor anomalies still exist in the space heating subsystem and the auxiliary
fossil fuel energy supply.

ENERGY SAVINGS

The solar energy system provided a total fossil fuel energy savings of 13.1
million Btu at an expense of 0.5 million Btu of electrical energy. The DHW
subsystem provided fossil fuel energy savings of 7.9 million Btu, while the
space heating subsystem contributed a fossil fuel energy savings of 5.2 mil-
lion Btu.

III. ACTION STATUS

Plans have not been formulated to correct the identified sensor anomalies at
this site.
