MONTHLY PERFORMANCE REPORT


SADDLE HILL TRUST
LOT 36

MARCH 1979


I. SYSTEM DESCRIPTION

Saddle Hill Trust Lot 36 is a single-family residence in Medway, Massachusetts.
Solar energy is used for space heating the home and preheating domestic hot
water (DHW). The system has an array of flat-plate collectors with a gross
area of 315 square feet. The array faces south at an angle of 58 degrees to
the horizontal. A 60 percent glycerol solution is the transfer medium that
delivers solar energy from the collector array to storage; water is the
transfer medium that delivers solar energy from storage to the space heating
and hot water loads. Solar energy is stored in the basement in a 750-gallon
storage tank. The tank is made of steel and lined with polyurethane. Preheated
city water is supplied, on demand, to a conventional 80-gallon DHW tank. When
solar energy is insufficient to satisfy the space heating load, an oil furnace
provides auxiliary energy for space heating. Similarly, a conventional elec-
tric 80-gallon DHW heater provides auxiliary energy for water heating. The
system, shown schematically in Figure 1, has three modes of solar operation.

Mode 1 Collector-to-Storage: This mode activates when the collector tempera-
ture is either more than 400F higher than storage temperature or higher than
1500F. Pump P1 is on. Solar energy transfer takes place through a heat
exchanger located inside the storage tank.

Mode 2 Storage-to-Space Heating: This mode activates when there is a
demand for space heating, storage temperature is 700F or higher, and house
temperature is lower than storage temperature. Pump P3 is on. Solar energy
transfer takes place through a heat exchanger located inside the air duct.

Mode 3 Storage-to-DHW Tank: This mode activates when storage water is 50F
higher than water in the DHW tank. Pump P2 is on. Solar energy transfer
takes place through a heat exchanger located inside the DHW heater.


II. PERFORMANCE EVALUATION


INTRODUCTION

The site was occupied in March and the solar energy system operated continuously
during the month. Solar energy satisfied 67 percent of the DHW requirements
and 25 percent of the space heating requirements. The solar energy system
provided electrical energy savings of 2.2 million Btu and fossil fuel energy
savings of 3.1 million Btu.

WEATHER CONDITIONS


During the month, total incident solar energy on the collector array was
11.4 million Btu for a daily average of 1168 Btu per square foot. This was
below the estimated average daily solar radiation for this geographical area
during March of 1198 Btu per square foot for a south-facing plane with a tilt
of 58 degrees to the horizontal. The average ambient temperature during March
was 410F as compared with the long-term average for March of 380F. The
number of heating degree-days for the month (based on a 650F reference) was
751, as compared with the long-term average of 834.

THERMAL PERFORMANCE

System During March 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 4.5 million Btu versus an estimated 5.7 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 4.3 million Btu.
System total solar fraction was 32 percent versus an estimated 53 percent.

Collector The total incident solar radiation on the collector array for the
month of March was 11.4 million Btu. During the period the collector loop
was operating, the total insolation amounted to 9.0 million Btu. The total
collected solar energy for the month of March was 4.5 million Btu, resulting
in a collector array efficiency of 39 percent, based on total incident insola-
tion. Solar energy delivered from the collector array to storage was 4.5
million Btu. Operating energy required by the collector loop was 0.090 million
Btu.

Storage Solar energy delivered to storage was 4.5 million Btu. There were
4.3 million Btu delivered from storage to the DHW and space heating subsystems.
Energy loss from storage was 0.33 million Btu. This loss represented 7 per-
cent of the energy delivered to storage. The storage efficiency was 93 per-
cent: 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 1140F.

DHW Load The DHW subsystem consumed 2.5 million Btu of solar energy and
1.1 million Btu of auxiliary electrical energy to satisfy a hot water load
of 1.3 million Btu. The solar fraction of this load was 67 percent. Losses
from the DHW subsystem were 2.3 million Btu. The DHW subsystem consumed a
total of 0.18 million Btu of operating energy, resulting in an electrical
energy savings of 2.3 million Btu. A daily average of 51 gallons of DHW was
consumed at an average temperature of 1390F delivered from the tank.

Space Heating Load The space heating subsystem consumed 1.8 million Btu of
solar energy and 8.9 million Btu of auxiliary fossil fuel energy to satisfy a
space heating load of 7.2 million Btu. The solar fraction of this load was
25 percent. The space heating subsystem consumed a total of 2.5 million Btu
of operating energy, resulting in an electrical energy expense of 0.033 mil-
lion Btu and a fossil fuel energy savings of 3.1.

OBSERVATIONS


The DHW loop pump was on continuously throughout the month and was a prime
contributor to the 2.3 million Btu energy loss in the DHW subsystem.


ENERGY SAVINGS

The DHW subsystem provided an electrical energy savings of 2.3 million Btu.
The space heating subsystem incurred an electrical energy expense of 0.033
million Btu and provided a fossil fuel energy savings of 3.1 million Btu.


III. ACTION STATUS


Boeing has been in contact with the system designer.
to investigate DHW subsystem operation.
