BLAKEDALE PROFESSIONAL CENTER
APRIL 1979

I. SYSTEM DESCRIPTION

The Blakedale Professional Center solar energy system is designed to pro-
vide 85 percent of the space heating requirements and 100 percent of the
domestic hot water heating requirements for a 4,400 square foot office suite
in Greenwood, South Carolina. Solar energy is collected by 53 flat-plate
collectors, which are manufactured by PPG Industries. The collectors, hav-
ing a gross area of 954 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 percent water
and one percent corrosion inhibitor. 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 covered with a water-
proof coating. When solar energy is inadequate, auxiliary space heating is
provided by a 10-ton heat pump and a 36-kilowatt electric resistance heater.
Auxiliary hot water heating is provided by an electrical element in a 40-
gallon tank. 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 difference
between the temperature of the collector and the temperature of water near
the bottom of the water thermal storage is greater than 19*F. Pump P1
circulates water through the collectors to transfer solar energy to the
water thermal storage. This mode terminates when the temperature differ-
ential is less than 6*F, or the temperature of water in the collector is
less than 370F.

Mode 2 Storage-to-Office Area (Solar): This mode is entered when heat
is required in the office area. Pump P2 circulates water through the water
thermal storage to heat exchanger HX2 in the air-handling unit. This mode

terminates when the supply air temperature is greater than 120*F, as the
circulation bypasses this heat exchanger by the action of the motorized
valve, or the requirement for heat is satisfied.

Mode 3 Storage-to-Office Area (Auxiliary): Although this mode is not a
solar mode of operation, it is entered concurrently with Mode 2 when heat
is required in the office and the office return air temperature is less
than 65*F. A 10-ton heat pump is energized to provide thermal energy to
heat exchanger HX3. When the outside air temperature is less than 400F,
two 18-kilowatt electric resistance heaters are energized in stages to pro-
vide auxiliary energy to heat exchanger HX4. This mode terminates when the
office return air temperature is greater than 680F, or the requirement for
heat is satisfied.

Mode 4 Domestic Hot Water Preheating: This mode is entered when there is
a requirement for hot water. As hot water is drawn, cold water passes
through heat exchanger HX1 in the water thermal storage, and subsequently
through the water heater and tempering valve to provide 1200F water. This
mode terminates when the requirement for hot water is satisfied.

II. PERFORMANCE EVALUATION

The system performance evaluations discussed in this section are based
primarily on the analysis of the data presented in the attached computer-
generated monthly report. This attached report consists of daily site
thermal and energy values for each subsystem, plus environmental data.
The performance factors discussed in this report are based upon the
definitions contained in NBSIR 76-1137, Thermal Data Requirements and
Performance Evaluation Procedures for the National Solar Heating and
Cooling Demonstration Program.

A. Introduction

The Blakedale Professional Center solar energy system was operational for
the first 20 days in April. After April 20, the solar energy system was







shut down for the summer as the heating season was essentially completed.
There were some minor space heating requirements after April 20 but these
were satisfied by the heat pump auxiliary system.

Since the solar energy system did not operate after April 20, some of the
daily averages presented in the attached computer generated monthly report
will be in error. This is because the daily averages are based on the full
30-day month, rather than the fraction of the month that the solar energy
system was operational. The daily averages that will be affected are those
that primarily relate to the operation of the solar energy system. These
would include such things as solar energy collected, collector array ef-
ficiency, various operating energies, most of the storage subsystem parameters
and all space heating subsystem parameters that are based on some solar energy
contribution.

During April, the solar energy system satisifed 52 percent of the total
space heating load. However, the solar fraction was 58 percent for the first
20 days of the month. The net electrical energy savings for the space heat-
ing subsystem were 0.10 million Btu, but, overall, the system operated at
a net loss of 0.13 million Btu for the month.

During April, there were some control system problems that resulted in
anomalous operation of the pumps (Pl and P2) in the solar energy system.
These problems were discussed in detail in the March report, and they result
essentially in an unnecessary waste of both solar and auxiliary energy.
Unscheduled operation of pump PI resulted in 0.23 million Btu of solar
energy being removed from storage and lost through transport losses or by
rejection from the collector array. During periods when the solar portion
of the space heating subsystem was operating (9 of the first 20 days in the
month), excessive operation of pump P2 caused an excess consumption of 0.40
million Btu of operating energy and a loss of approximately 0.75 million Btu
of solar energy.







B. Weather


During April, the measured average outside ambient temperature was 66*F.
This was four degrees above the long-term average ambient temperature of
62F and reduced the building heating load. The measured value for inso-
lation incident in the plane of the collector array was 1,424 Btu/ft2-day,
and this was 12 percent below the long-term average of 1,625 Btu/ft2-day.
Long-term average temperature data and long-term average insolation data
are taken from Reference Monthly Environmental Data for Systems in the
National Solar Data Network, Department of Energy Report SOLAR/0019-79/36.

C. System Thermal Performance

Collector During the reporting period, a total of 40.76 million Btu of
incident solar energy was measured in the plane of the collector array.
The system collected a net amount of 6.42 million Btu, or 16 percent of the
total available insolation. During the time when the system was operating,
a total of 22.29 million Btu of solar energy was incident on the array.
This represents an operational collector efficiency of 29 percent. A total
of 0.23 million Btu of electrical energy was required to operate the col-
lector array. However, part of this operating energy expenditure was due
to unscheduled operation of pump Pl, and this allowed 0.23 million Btu of
stored solar energy to be rejected from the collector array to the atmosphere.

Storage During April, a total of 6.60 million Btu was delivered to the
storage tank. However, the unscheduled operation of pump P1 caused 0.60
million Btu to be removed from storage and lost, either through the col-
lector array (0.23 million Btu) or the system piping (0.37 million Btu).
Therefore, there was a net amount of 6.00 million Btu delivered to storage
during the month.







A total of 2.62 million Btu was removed from storage during the reporting
period. Since 1.85 million Btu was actually delivered to the space heating
subsystem, there were 0.77 million Btu in transport losses. The significant
point regarding these transport losses is that the majority of them (0.75
million Btu) resulted from the excessive operation of pump P2.

The change in stored energy was 0.21 million Btu and this, combined with the
energy supplied to and removed from storage, resulted in a thermal loss from
storage of 3.17 million Btu. Storage was maintained at an average tempera-
ture of 118*F, and the monthly storage efficiency was 0.47.

Hot Water Load The hot water load at the Blakedale Professional Center is
very small. The make-up water is heated by the storage tank and the electri-
cal auxiliary system is not used. Therefore, although the solar energy
system carries the entire hot water load, this load is small enough to be
neglected.

Space Heating Load The space heating load for April was 3.55 million Btu.
However, this value represents the load for the entire month. During the
period when the solar energy system was active, the total space heating load
was 3.17 million Btu and solar energy satisfied 1.85 million Btu or 58 per-
cent of this load. The remainder of the energy required for space heating
was delivered by the heat pump.

As noted in the storage section, 0.75 million Btu of solar energy were
wasted by the space heating subsystem due to excessive operation of pump P2.
This represents 41 percent of the total amount of solar energy that was
delivered to the space heating load.

During April, the total amount of energy delivered to the space heating sub-
system maintained an average building temperature of 730F. The average
outdoor ambient temperature was 66F.







D. Observations


The April operation of the Blakedale Professional Center solar energy system
was somewhat degraded due to the control problems previously discussed. This
installation has a relatively large energy collection and storage subsystem
(ECSS), when compared to the actual size of the building, and a higher level
of performance should be expected from this solar energy system.

E. Energy Savings

During April, the space heating subsystem realized a net savings of only
0.10 million Btu. However, when the 0.23 million Btu of electrical energy
required to operate the ECSS is considered, then the overall system actually
operated at a loss of 0.13 million Btu for the month. Part of this loss
was due to the unscheduled operation of pump Pl, but the majority of the
loss came from the excessive operation of pump P2. This pump consumed 0.40
million Btu of electrical energy by operating during periods when no solar
energy was being supplied to the space heating subsystem. If the system had
been operating properly, the net savings for April would have been at least
0.27 million Btu.

III. ACTION STATUS

The system contractor is aware of the existing control problems. However,
it is not known at the present time what action will be taken to correct them
prior to the start of the next heating season.
