MONTHLY PERFORMANCE REPORT


J. D. EVANS, INC.
HOUSE A

APRIL 1979


I. SYSTEM DESCRIPTION

J. D. Evans, Inc., 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
l000-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 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 April and the solar energy system operated contin-
uously during the month. Solar energy satisfied 51 percent of the DHW require-
ments and 58 percent of the space heating requirements. The solar energy
system provided electrical energy savings of 0.68 million Btu.


WEATHER CONDITIONS

During the month, total incident solar energy on the collector array was
12.9 million Btu for a daily average of 1228 Btu per square foot. This was
below the estimated average daily solar radiation for this geographical area
during April of 1467 Btu per square foot for a south-facing plane with a tilt
of 45 degrees to the horizontal. The average ambient temperature during April
was 510F as compared with the long-term average for April of 540F. The number
of heating degree-days for the month (based on a 65oF reference) was 412, as
compared with the long-term average of 340.


THERMAL PERFORMANCE

System During April 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
collected was 2.8 million Btu versus an estimated 2.3 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 1.5 million Btu.
System total solar fraction was 56 percent versus an estimated 58 percent.

Collector The total incident solar radiation on the collector array for the
month of April was 12.9 million Btu. During the period the collector loop was
operating, the total insolation amounted to 9.1 million Btu. The total col-
lected solar energy for the month of April was 2.8 million Btu, resulting in a
collector array efficiency of 22 percent, based on total incident insolation.
Solar energy delivered from the collector array to storage was 2.8 million
Btu. Operating energy required by the collector loop was 0.15 million Btu.

Storage Solar energy delivered to storage was 2.8 million Btu. There were
1.5 million Btu delivered from storage to the DHW and space heating subsystems.
Energy loss from storage was 1.3 million Btu. This loss represented 46 percent
of the energy delivered to storage. The storage efficiency was 54 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 124F.

DHW Load The DHW subsystem consumed 0.38 million Btu of solar energy and
0.43 million Btu of auxiliary electrical energy to satisfy a hot water load
of 0.65 million Btu. The solar fraction of this load was 51 percent. Losses









from the DHW subsystem were 0.16 million Btu. The DHW subsystem consumed no
operating energy, resulting in an electrical energy savings of 0.38 million
Btu. A daily average of 29 gallons of DHW was consumed at an average tempera-
ture of 140F delivered from the tank.

Space Heating Load The space heating subsystem consumed 1.1 million Btu of
solar energy and 0.34 million Btu of auxiliary electrical energy to satisfy a
space heating load of 1.8 million Btu. The heat pump supplied a load of 0.78
million Btu. The solar fraction of the space heating load was 58 percent.
The space heating subsystem consumed a total of 0.17 million Btu of operating
energy, resulting in an electrical energy savings of 0.45 million Btu. The
average ambient temperature inside the house was 690F.


OBSERVATIONS

The flow sensor in the collector loop was not functioning. A historical
average value of the fluid flow was used in the calculation of collected solar
energy. 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 0.68
million Btu. The DHW subsystem provided an electrical energy savings of 0.38
million Btu, while the space heating subsystem contributed an electrical energy
savings of 0.45 million Btu.


III. ACTION STATUS

Boeing/IBM is expected to investigate the collector loop flow sensor.
