MAY 1979

I. SYSTEM DESCRIPTION


The Brad Popkin site is a single-family residence in Carrollton, Texas. The
home has approximately 2300 square feet of conditioned space. Solar energy is
used for space heating and preheating domestic hot water (DHW). The solar
energy system has an array of seven flat-plate collectors with a gross area of
248 square feet. The array faces south at an angle of 46 degrees to the hori-
zontal. Air is the transfer medium that delivers solar energy from the
collector array to storage and to the space heating load. Solar energy is
stored aboveground in two 144-cubic-foot bins, each containing 7 tons of rock.
The bins are 12 feet high by 4 feet in diameter with 3-inch concrete walls and
4 inches of fiberglass insulation. 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 electrical heating element in the air-handling unit
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 six modes of solar operation.


Mode 1 Collector-to-Storage: This mode activates when temperature sensors
detect a temperature difference of 400F across the collector array. The
collector loop fan turns on and pushes the heated air through rock storage.


Mode 2 Collector-to-Space Heating Solar Only: This mode activates when
the collector loop fan is on and there is a demand for space heating and the
temperature in the rock storage bins is equal to or greater than 900F.


Mode 3 Collector-to-Space Heating Solar Plus Heat Strips: This mode
activates when the collector loop fan is on and there is a demand for space
heating and the temperature in the rock storage bins is greater than 700F but
less than 900F.

Mode 4 Storage-to-Space Heating Solar Only: This mode activates when
there is a demand for space heating and the temperature in the rock storage
bins is equal to or greater than 90F.


Mode 5 Storage-to-Space Heating Solar Plus Heat Strips: This mode acti-
vates when there is a demand for space heating and the temperature in the rock
storage bins is greater than 70F but less than 90F.


Mode 6 Space Heating Heat Strips Only: This mode activates when there is
a demand for space heating and the temperature in the rock storage bins is
less than 70F.


Mode 7 Collector-to-DHW Preheat: This mode activates when the collector
loop fan is on and the temperature difference across the heat exchanger unit
(water side) is equal to or greater than 12F. During summer operation,
damper D4 closes and damper D2 opens, thus creating a closed loop for DHW
preheat only.



II. PERFORMANCE EVALUATION



INTRODUCTION


The site was unoccupied in May and the solar energy system operated con-
tinuously during the month. Total solar energy collected was 1.7 million
Btu and the total solar energy used was 0.15 million Btu or 8 percent of the
collected energy. The change in stored energy was -0.08 million Btu and the
total system losses amounted to 1.6 million Btu. Solar energy satisfied
9 percent of the DHW requirements and 11 percent of the space heating require-
ments. The solar energy system provided a net electrical savings of 0.016
million Btu.








WEATHER CONDITIONS


During the month, total incident solar energy on the collector array was
10.8 million Btu for a daily average of 1406 Btu per square foot. This was
below the estimated average daily solar radiation for this geographical area
during May of 1516 Btu per square foot for a south-facing plane with a tilt of
46 degrees to the horizontal. The average ambient temperature during May was
70F as compared with the long-term average for May of 740F. The number of
heating degree-days for the month (based on a 650F reference) was 32, as
compared with the long-term average of zero. The number of cooling degree-
days was 151, as compared with the average of 273.



THERMAL PERFORMANCE


System During May 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 input. 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 0.15 million Btu versus
an estimated 0.70 million Btu. System total solar fraction was 11 percent
versus an estimated 100 percent.


Collector The total incident solar radiation on the collector array for the
month of May was 10.8 million Btu. During the period the collector loop was
operating, the total insolation amounted to 5.9 million Btu. The total col-
lected solar energy for the month of May was 1.7 million Btu, resulting in a
collector array efficiency of 16 percent, based on total incident insolation.
Solar energy delivered from the collector array to storage was 1.7 million
Btu, while solar energy delivered from the collector array directly to the
loads amounted to 0.15 million Btu. Because of its design and location, this
solar energy site has the potential for storing more energy than is collected.
This is because the entire solar energy system (except for the two rock storage
bins) is located in the attic. Temperatures in the attic easily reach 125F







during the day and sensor T200 has recorded 90OF at midnight. As in most air
systems, when the collector loop blower (EP 100) goes off, there continues to
be low-level air flow due to leakage, natural convection and dampers not fully
closing. At this site, this low-level air flow is through the attic ducts,
and continues to add solar energy to the rock storage bins after the collector
loop blower has stopped. For May, the excess of stored energy plus energy
directly to load over collected energy was 0.14 million Btu. This imbalance
will be monitored in forthcoming months. Operating energy required by the
collector loop was 0.11 million Btu.


Storage Solar energy delivered to storage was 1.7 million Btu. There was
no energy delivered from storage to the space heating subsystem. Energy loss
from storage was 1.8 million Btu. This loss represented 100 percent of the
energy delivered to storage. The storage efficiency was a negative 4 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 890F. A negative effi-
ciency at this time of the year is consistent with the site design and opera-
tion. Damper D4 was closed on May 15 and prevented collected solar energy
from reaching storage. This will allow the storage bins to cool and reach a
minimum temperature level, until temperature buildup resumes in the fall
heating season.


DHW Load Since there was only a total of 3 gallons of DHW consumed during
May, a meaningful analysis and discussion of this subsystem cannot be
accomplished.


The preheat loop pump was replaced as scheduled by the grantee. The DHW
subsystem consumed 0.15 million Btu of auxiliary electrical energy during
May to maintain an average output temperature of 1400F.


Space Heating Load The space heating subsystem consumed 0.053 million Btu of
solar energy and 0.43 million Btu of auxiliary electrical energy to satisfy a







space heating load of 0.48 million Btu. The solar fraction of this load was
11 percent. The space heating subsystem consumed a total of 0.022 million Btu
of operating energy, resulting in an electrical energy savings of 0.031 million
Btu.



OBSERVATIONS


This site is now operating in summer status (i.e., damper D4 is closed) and
the only solar mode is collector to DHW preheat. Therefore, site reporting
will be minimal until space heating is again required.



ENERGY SAVINGS


The solar energy system provided a net electrical energy savings of 0.016
million Btu. The DHW subsystem provided an electrical energy savings of 0.093
million Btu, while the space heating subsystem contributed an electrical
savings of 0.031 million Btu.



III. ACTION STATUS


No action is required at this time.
