MONTHLY PERFORMANCE REPORT


J. D. EVANS, INC.
HOUSE A

FEBRUARY 1979


I. SYSTEM DESCRIPTION

J. D. Evans, House A is one of two instrumented single-family residences in
Columbia, Maryland. The home has approximately 2250 square feet of condi-
tioned space. Solar energy is used for space heating the home and preheating
domestic hot water (DHW). The solar energy system has an array of flat-plate
collectors with a gross area of 350 square feet. The array faces 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. Solar energy is stored in the basement in a
1000-gallon steel storage tank. Incoming city water is preheated in a liquid-
to-liquid heat exchanger located in the storage tank and then flows into a
conventional 40-gallon DHW tank. When solar energy is insufficient to satisfy
the space heating load, a heat exchanger within a heat pump and an electrical
heating element in the air-distribution duct provides auxiliary energy for
space heating. Similarly, an electrical heating element in the DHW tank
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 temperature
difference between the storage tank and the collector outlet is higher than
15F. Water circulates from the storage tank through the collector until a
temperature difference of less than 5F is reached.

Mode 2 Storage-to-Space Heating: This mode activates when thermal energy
for space heating is requested by the room thermostat. Solar-heated water
from storage circulates through a liquid-to-air heat exchanger in the space
heating air duct. If solar energy is insufficient to satisfy the space
heating load, the heat pump and/or the auxiliary electrical heating element
will be activated. The electrical strip heater can also be manually operated
without solar heating and heat pump operation.

Mode 3 DHW Preheating: This mode is activated by drawing hot water from the
system. Cold supply water is preheated in a liquid-to-liquid heat exchanger
located in the solar energy storage tank before flowing to the DHW tank. If
the required DHW tank temperature is not maintained by solar preheating,
auxiliary energy is provided by the electrical heating element in the DHW
tank.


II. PERFORMANCE EVALUATION


INTRODUCTION

The site was occupied in February and the solar energy system operated contin-
uously during the month. Solar energy satisfied 19 percent of the DHW requirements

and 7 percent of the space heating requirements. The solar energy system
provided electrical savings of 0.8 million Btu. No data was collected during
the first 13 days of the month. The Site Data Acquisition Subsystem (SDAS)
was repaired and put back into operation on February 13.


WEATHER CONDITIONS

During the month, total incident solar energy on the collector array was 9.1
million Btu for a daily average of 925 Btu per square foot. This was below
the estimated average daily solar radiation for this geographical area during
February of 1205 Btu per square foot for a south-facing plane with a tilt of
45 degrees to the horizontal. The average ambient temperature during February
was 26F as compared with the long-term average for February of 35F.


THERMAL PERFORMANCE

Collector The total incident solar radiation on the collector array for the
month of February was 9.1 million Btu. During the period the collector loop
was operating the total insolation amounted to 6.6 million Btu. The total
collected solar energy for the month of February was 2.5 million Btu, resulting
in a collector array efficiency of 27 percent, based on total incident insola-
tion. Solar energy delivered from the collector array to storage was 2.5
million Btu. Operating energy required by the collector loop was 0.11 million
Btu.

Storage Solar energy delivered to storage was 2.5 million Btu. There were
1.3 million Btu delivered from storage to the DHW and space heating subsystems.
Energy loss from storage was 0.76 million Btu. This loss represented 31 per-
cent of the energy delivered to storage. The storage efficiency was 69
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 87F.

DHW Load The DHW subsystem consumed 0.14 million Btu of solar energy and
0.64 million Btu of auxiliary electrical energy to satisfy a hot water load
of 0.61 million Btu. The solar fraction of this load was 19 percent. Losses
from the DHW subsystem were 0.17 million Btu. The DHW subsystem consumed no
operating energy, resulting in an electrical energy savings of 0.14 million
Btu. A daily average of 26 gallons of DHW was consumed at an average tempera-
ture of 142F delivered from the tank.

Space Heating Load The space heating subsystem consumed 1.1 million Btu of
solar energy and 7.7 million Btu of auxiliary electrical energy to satisfy a
space heating load of 15.8 million Btu. The heat pump supplied a load of
14.7 million Btu. The solar fraction of the space heating load was 7 percent.
The space heating subsystem consumed a total of 0.95 million Btu of operating
energy, resulting in an electrical energy savings of 0.77 million Btu. The
average ambient temperature inside the house was 68F.









OBSERVATIONS


There was no data collected during the first 13 days of the month. The SDAS
was repaired and put back into operation on February 13. Data was collected
and processed from February 13 to the end of the month.

The net loss of collected solar energy on February 13 was caused by the
forced system operation at low incident radiation for systems test.


ENERGY SAVINGS

The solar energy system provided a net electrical energy savings of 0.8
million Btu. The DHW subsystem provided an electrical energy savings of 0.14
million Btu, while the space heating subsystem contributed an electrical
energy savings of 0.8 million Btu.


III. ACTION STATUS

No action is required at this time.
