SADDLE HILL TRUST
LOT 36

MAY 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 40oF higher than storage temperature or higher than
150F. 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 70F 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 5F
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 May and the solar energy system operated continuously
during the month. Total solar energy collected was 4.0 million Btu and the
total solar energy used was 3.0 million Btu or 75 percent of the collected
energy. Stored energy increased by 0.044 million Btu and storage losses
amounted to 0.92 million Btu. Solar energy satisfied 84 percent of the DHW
requirements and 58 percent of the space heating requirements. The solar
energy system provided an electrical energy savings of 2.7 million Btu and a
fossil fuel energy savings of 0.072 million Btu.



WEATHER CONDITIONS


During the month, total incident solar energy on the collector array was
11.6 million Btu for a daily average of 1186 Btu per square foot. This was
below the estimated average daily solar radiation for this geographical area
during May of 1274 Btu per square foot for a south-facing plane with a tilt
of 58 degrees to the horizontal. The average ambient temperature during May
was 610F as compared with the long-term average for May of 590F. The number
of heating degree-days for the month (based on a 650F reference) was 165, as
compared with the long-term average of 218. The number of cooling degree-
days was 41, as compared with the average of 20.



THERMAL PERFORMANCE


System During May the solar energy system performed approximately the same
as expected. The expected performance was determined from a modified f-chart
analysis using measured weather and subsystem loads as input. Sclar energy
used by the system was estimated by assuming that all energy collected would









be applied to the load. Actual solar energy used was 3.0 million Btu versus
an estimated 3.2 million Btu. System total solar fraction was 83 percent
versus an estimated 88 percent.


Collector The total incident solar radiation on the collector array for
the month of May was 11.6 million Btu. During the period the collector loop
was operating, the total insolation amounted to 8.3 million Btu. The total
collected solar energy for the month of May was 4.0 million Btu, resulting
in a collector array efficiency of 34 percent, based on total incident
insolation. Solar energy delivered from the collector array to storage was
4.0 million Btu. Operating energy required by the collector loop was 0.10
million Btu.


Storage Solar energy delivered to storage was 4.0 million Btu. There were
3.0 million Btu delivered from storage to the DHW and space heating subsystems.
Energy loss from storage was 0.92 million Btu. This loss represented 23
percent of the energy delivered to storage. The storage efficiency was 77
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 137F.


DHW Load The DHW subsystem consumed 3.0 million Btu of solar energy and
0.53 million Btu of auxiliary electrical energy to satisfy a hot water load
of 1.4 million Btu. The solar fraction of this load was 84 percent.
Losses from the DHW subsystem were 2.1 million Btu. The DHW subsystem
consumed a total of 0.18 million Btu of operating energy, resulting in an
electrical energy savings of 2.8 million Btu. A daily average of 60 gallons
of DHW was consumed at an average temperature of 144F delivered from the
tank.


Space Heating Load The space heating subsytem consumed 0.04 million Btu of
solar energy and 0.51 million Btu of auxiliary fossil fuel energy to satisfy
a space heating load of 0.74 million Btu. The solar fraction of this load
was 58 percent. The space heating subsystem consumed a total of 0.02
million Btu of operating energy, resulting in a fossil fuel energy savings
of 0.07 million Btu.









OBSERVATIONS


Adjustments were made to the DHW control system on May 24 to improve pump
regulation and reduce power consumption.



ENERGY SAVINGS


The solar energy system provided an electrical energy savings of 2.7 million
Btu and a fossil fuel energy savings of 0.072 million Btu. The DHW subsystem
provided an electrical energy savings of 2.8 million Btu. The space heating
subsytem contributed a fossil fuel energy savings of 0.072 million Btu.
