BLAKEDALE PROFESSIONAL CENTER
MARCH 1979


I. SYSTEM DESCRIPTION


The Blakedale Professional Center solar energy system is designed to
provide 85 percent of the space heating load and 100 percent of the
domestic hot water load for a 4,400 square foot office suit in Green-
wood, South Carolina. Solar energy is collected by 53 flat-plate
collectors, which are manufactured by PPG Industries. The collectors,
having a gross area of 964 square feet, are arranged in three banks and
are mounted on the roof. Each collector array faces south at an angle
of 45 degrees from the horizontal. The heat transfer medium is 99 per-
cent water and one percent corrosion inhibitors. Solar Energy is stored
in a 5,000-gallon tank that is buried under the parking lot. The tank
is insulated with four inches of sprayed-on polyurethane which is cov-
ered with a waterproof coating. When solar energy is inadequate, auxi-
liary space heating is provided by a 10-ton heat pump and a 36-kilowatt
electric resistance heater. Auxiliary hot water heating is provided by
a 40-gallon electric heater. Freeze protection is provided by a drain-
down system.


The system, shown schematically in Figure 1, has four modes of operation:


Mode 1 Collector-to-Storage: This mode is entered when the temperature
of the collector is 190F higher than the temperature of water near the
bottom of the water thermal storage. Pump P1 circulates water through
the collectors to transfer solar energy to the water thermal storage.
This mode terminates when the temperature differential is less than 6F,
or the temperature of water in the collector is less than 37F.


Mode 2 Storage-to-Office Area (Solar): This mode is entered when heat
is required in the office area and the storage temperature is greater
than 100F. Pump P2 circulates water through the water thermal storage

to heat exchanger HX2 in the air-handling unit. This mode terminates
when the temperature of the air supplied to the building is g eater t'an
120F, when the motorized valve bypasses this heat exchanger; or tQe
thermostat demand for heat is satisfied.


Mode 3 Storage-to-Office Area (Auxiliary): Although this i.de is not
a solar o-:'de of operation, it is entered concurrently with Mode 2 whe-i
heat is required in the office and the office return air temperatu.'- is
less than 650F. A 10-ton heat puL:r. is energized to provide thermal energy
to heat exchanger HX3. WhMn the outside air temperature is less t'.n 40F,
two 18-kilowatt electric resistance heaters are energized in sta.-s to pro-
vide auxiliary energy to heat exchanger HX4. This -ode terminates w he
the office return air temperature is greater than 68F, or the thermostat
dco.nd for Qeat is satisfied.


Mode 4 Domestic Hot Water Preheatinq: This mode is entered ?hen there
is a requirement for hot water. As hot water is drawn, cold water fror the
service mains passes through heat exchanger HX1 in the water thermal storaco.
This "nJe terminates "i.en the requi",' -nt for hot water is satisfied.


II. PERFOPR.,NCE EVALUATION


The s,:.t-' perfor'-nce evaluatic:s discussed in this section are based
primarily on the a-alysis of the data presented in the attach-' crl ,uter-
generated monthlyy report. This attached report consists of daily site
thern-l and energy values for each subsystem, plus environmental data.
The perforr-nce factors discussed in this report are based upon the
definitions contained in NBSIR 76-1137, Thermal Data Requir:--nts and
Performance Evaluation Procedures for the National Solar Heating ar:
Cooling Denanstration Program.


A. Introduction


During March, 33 percent of the 9.77 million Btu system load for space
heating j..;s provided by solar energy. However, the resident cont :ctor

urot continue, usly. This excessive operation required an ad-
ior 1 3.72 iion "tu of electrical energy, and resulted in an addi-
r l tarnsp rt loss of 0. 11ili .r Btu of solar energy. The additional
r i erij r jes the electrical energy savings associated with the
r c *i ti:it n to the s. ce '.:-ating load. The electrical savings of

B. Weather


During March, the temperature in Greenwood, South Carolina was warmer than
normal, as evidenced by an average ambient (outside) temperature of 590F
when compared to the long-term value of 500F. This long-term value was
obtained from the climatological data for the nearby city Greenville, SC.
In addition, there was more cloud cover than normal, as evidenced by an
average daily insolation of 1,503 Btu/ft2 when compared to the long-term
value of 1,661 Btu/ft2. This long-term value was obtained from an algo-
rithm that projects the mean daily horizontal insolation onto the plane
of the collectors.


C. Thermal Performance


Collector During March, 44.44 million Btu of solar energy were incident
upon the collector array, and 30.47 million Btu were incident during the
operation of this subsystem. From this, a gross amount of 9.88 million
Btu was collected.


Due to the abnormal operation of pump P1, the temperature of water enter-
ing the collectors was greater than the temperature of water that was
leaving for short periods of tire. As a result, 0.24 million Btu of solar
energy was transferred from thermal storage to the collectors, and sub-
sequently dissipated to the environment. This process was accelerated
when the subsystem cycled frequently, as during periods of -rrginal or
intermittent insolation, making the net daily value for collected solar
energy negative on two days. Consequently, the amount of collected
solar energy and the collector array efficiency was smaller than normal.
The net amount of collected solar energy was 9.64 million Btu, and the
collector array efficiency was 22 percent, with an operational efficiency
of 32 percent. A total of 0.35 million Btu of electrical energy was
required to operate the subsystem.


Pump PI did not always start operating autor',.tically upon the availability
of solar energy at the collectors, although it always stopped automatically.

The resident contractor modified the control system for this subsystem
on March 5, whereby he operated pump P2 continuously. The operation
forced the control system to circulate solar energy from storage to the
load distribution valve regardless of demand. During periods of time in
which solar energy was not delivered to heat exchanger HX2, the operation
of this pump required 0.72 million Btu of electrical energy, and resulted
in a transport loss of 0.82 million Btu of solar energy.


D. Observations


During March, an estimated 5.12 million Btu of solar energy was lost to
the environment from the energy collection and storage subsystem. These
losses were composed of 0.24 million Btu from the collectors due to the
excessive operation of this subsystem, 1.35 million Btu from transporta-
tion of the heat transfer medium, and an estimated 3.53 million Btu from
storage. Although the latter value is large, it is not possible to dif-
ferentiate between normal storage losses and evaporation losses.


For the space heating subsystem, 0.96 million Btu of solar energy were
lost to the environment. This loss occurred during transfer of solar
energy from thermal storage to this subsystem. However, 0.82 million Btu
of the 0.96 million Btu were lost due to the excessive operation of pump
P2. In addition, 0.72 million Btu of electrical energy were required to
support this excessive operation, and resulted in a corresponding decrease
in electrical energy savings.


E. Energy Savings


During March, essentially zero Btu of electrical energy savings were real-
ized from the operation of this solar energy heating system. These savings
were based on the energy requirements of a heat pump whose fraction of the
load is a function of both ambient (outside) and building (inside) tempera-
tures and whose coefficient of performance is a function of the ambient
temperature. These savings are near zero primarily because of the addi-
tional electrical energy required for the excessive operation of pump P2
and the additional solar energy lost from the transport of the heat transfer
medium.
