MONTECITO PINES

APRIL 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 eight-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 P1 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 VI 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 in April and the solar energy system operated contin-
uously during the month. Solar energy satisfied 59 percent of the DHW require-
ments and 33 percent of the space heating requirements. The solar energy

system provided a fossil fuel energy savings of 17.4 million Btu at an expense
of 0.67 million Btu of electrical energy.


WEATHER CONDITIONS

During the month, total incident solar energy on the collector array was
48.5 million Btu for a daily average of 1703 Btu per square foot. This was
below the estimated average daily solar radiation for this geographical area
during April of 1827 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 tem-
perature during April was 53F as compared with the long-term average for
April of 56F. The number of heating degree-days for the month (based on a
65F reference) was 360, as compared with the long-term average of 279.


THERMAL PERFORMANCE

System During April the solar energy system performed somewhat poorer than
expected. The expected performance was determined from a modified f-chart
analysis using measured weather and subsystem loads as inputs. Solar energy
collected was 13.4 million Btu versus an estimated 15.8 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 10.4 million Btu.
System total solar fraction was 41 percent versus an estimated 50 percent.

Collector The total incident solar radiation on the collector array for the
month of April was 48.5 million Btu. During the period the collector loop was
operating, the total insolation amounted to 43.1 million Btu. The total
collected solar energy for the month of April was 13.4 million Btu, resulting
in a collector array efficiency of 28 percent, based on total incident insola-
tion. Solar energy delivered from the collector array to storage was 11.5
million Btu. Energy loss during transfer from the collector array to storage
was 1.8 million Btu. This loss represented 14 percent of the energy collected.
Operating energy required by the collector loop was 0.66 million Btu.

Storage Solar energy delivered to storage was 11.5 million Btu. There were
11.5 million Btu delivered from storage to the DHW and space heating subsystems.
Energy loss from storage was -0.08 million Btu. This loss represented 1 percent
of the energy delivered to storage. The storage efficiency was 99 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 108F.

DHW Load The DHW subsystem consumed 4.6 million Btu of solar energy and 6.2
million Btu of auxiliary thermal energy (equivalent to 7.7 million Btu of
auxiliary fossil fuel energy) to satisfy a hot water load of 7.8 million Btu.
The solar fraction of this load was 59 percent. Losses from the DHW subsystem
were 3.0 million Btu. The DHW subsystem consumed a total of 0.70 million Btu
of operating energy. A daily average of 451 gallons of DHW was consumed at an
average temperature of 135F delivered from the tank.








Space Heating Load The space heating subsystem consumed 5.8 million Btu of
solar energy and 15.2 million Btu of auxiliary thermal energy (equivalent to
19.0 million Btu of auxiliary fossil fuel energy) to satisfy a space heating
load of 17.8 million Btu. The solar fraction of this load was 33 percent.
Losses from the space heating subsystem were 3.3 million Btu. The space
heating subsystem consumed a total of 2.1 million Btu of operating energy.


OBSERVATIONS

The extremely low storage loss during April is the result of an exceptional
time-phase match between the collection and use of solar energy at this site.
Solar energy was collected and delivered to storage during 29 out of 30 days
in April; and solar energy was used for space heating for the same time period
during 25 days. The system design is such that incoming city water is pre-
heated at the same time that hot water is used. There was little time lag
between the collection of solar energy and its application to the DHW and
space heating loads; consequently, storage losses were minimal.


ENERGY SAVINGS

The solar energy system provided a total fossil fuel energy savings of 17.4
million Btu at an expense of 0.67 million Btu of electrical energy. The DHW
subsystem provided a fossil fuel energy savings of 7.7 million Btu. The
space heating subsystem contributed a fossil fuel energy savings of 9.7 million
Btu.
