MONTHLY PERFORMANCE REPORT


J. D. EVANS, INC.
HOUSE B

MARCH 1979


I. SYSTEM DESCRIPTION

J. D. Evans, Inc., House B 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 374 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
150F. Water circulates from the storage tank through the collector until a
temperature difference of less than 50F 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 of 140F is not maintained by solar preheat-
ing, auxiliary energy is provided by the electrical heating element in the DHW
tank.


II. PERFORMANCE EVALUATION


INTRODUCTION

The site was occupied in March and the solar energy system operated continuously
during the month. Solar energy satisfied 69 percent of the space heating

requirements. Solar fraction of the DHW load and DHW auxiliary electrical
energy were not determined because of problems with the DHW auxiliary energy
sensor.


WEATHER CONDITIONS

During the month, total incident solar energy on the collector array was 17.6
million Btu for a daily average of 1519 Btu per square foot. This was above
the estimated average daily solar radiation for this geographical area during
March of 1381 Btu per square foot for a south-facing plane with a tilt of 45
degrees to the horizontal. The average ambient temperature during March was
46F as compared with the long-term average for March of 430F. The number of
heating degree-days for the month (based on a 650F reference) was 607, as
compared with the long-term average of 688. The number of cooling degree-days
was 8, as compared with the average of zero.


THERMAL PERFORMANCE

System During March 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 inputs. 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 3.7 million Btu. The esti-
mated system solar fraction was 81 percent. The actual solar fraction could
not be determined because of a power-sensor problem with the DHW electrical
heater.

Collector The total incident solar radiation on the collector array for the
month of March was 17.6 million Btu. During the period the collector loop was
operating the total insolation amounted to 14.6 million Btu. The total collected
solar energy for the month of March was 4.5 million Btu, resulting in a collector
array efficiency of 26 percent, based on total incident insolation. Solar
energy delivered from the collector array to storage was 4.5 million Btu. Opera-
ting energy required by the collector loop was 0.15 million Btu.

Storage Solar energy delivered to storage was 4.5 million Btu. There were
3.7 million Btu delivered from storage to the DHW and space heating subsystems.
Energy loss from storage was 0.82 million Btu. This loss represented 18 percent
of the energy delivered to storage. The storage efficiency was 82 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 1120F.

DHW Load The DHW subsystem consumed 0.87 million Btu of solar energy and an
undetermined amount of auxiliary electrical energy to satisfy a hot water load
of 1.6 million Btu. The DHW subsystem contributed an electrical energy savings
of 0.87 million Btu. A daily average of 82 gallons of DHW was consumed at an
average temperature of 1170F delivered from the tank.

Space Heating Load The space heating subsystem consumed 2.8 million Btu of
solar energy and 0.81 million Btu of auxiliary electrical energy to satisfy a







space heating load of 4.1 million Btu. The heat pump supplied 0.75 million Btu
and the auxiliary electrical strip heater supplied 0.49 million Btu of the load
requirements. The solar fraction of the space heating load was 69 percent.
The space heating subsystem consumed a total of 0.42 million Btu of operating
energy, resulting in an electrical energy savings of 1.4 million Btu. The
average ambient temperature inside the house was 680F.


OBSERVATIONS

The electrical energy savings for the space heating subsystem were determined
based on conventional heating using a heat'pump.


ENERGY SAVINGS

The solar energy system provided a net electrical energy savings of 2.1
million Btu. The DHW subsystem provided an electrical energy savings of 0.87
million Btu, while the space heating subsystem contributed an electrical
energy savings of 1.4 million Btu.


III. ACTION STATUS

Boeing is expected to investigate the power sensor problem with the DHW electrical
heater.
