MONTHLY PERFORMANCE REPORT
CHARLOTTE MEDICAL CENTER
MAY 1979


I. SYSTEM DESCRIPTION


The Charlotte Medical Center, Charlotte, North Carolina, solar energy
system was designed to provide both space heating and domestic hot water
for a six-story medical library, office and classroom building. Solar
energy collection is accomplished by an array of General Electric flat-
plate collectors using a 50 percent (by volume) aqueous solution of
ethylene glycol. The collector array has a gross area of 4,020 square
feet and faces south at an angle of 35 degrees from the horizontal.
Storage capacity is 6,000 gallons of water in an underground tank. In
addition to the primary storage tank, there are three domestic hot water
(DHW) tanks, each of which has a capacity of 125 gallons. Auxiliary
heating for both subsystems is provided by electrical resistance heaters.
Each DHW tank contains a 12 kw electrical immersion heater. The space
heating subsystem has a capacity of 261 kw, of which 11 kw is contained
in supplementary baseboard heaters on the first floor of the building.


The system, shown schematically in Figure 1, has six basic modes of
operation.


Mode 1 Collector-to-Space Heating: This mode is entered whenever
there is a demand for space heating and the solar panel temperature is
above 1000F. Pump P1 is started when the solar panel temperature first
rises above 1000F, and will continue to run while either the solar panel
temperature is above 850F, or the water thermal storage temperature is
above 850F and the air-handling unit (AHU) is calling for heat. In this
mode, pump P1 circulates the solar heated ethylene glycol solution from the
collectors, through valve V2, heat exchanger HX2, valve V1, valve V4 and
back to the collectors. Thus, the solar heated solution flows from the
collectors directly to the space heating exchanger HX2; storage loop heat
exchanger HX4 is bypassed.

Mode 2 Collector-to-Space Heating and Storage: With the water thermal
storage temperature below 850F and the AHU calling for maximum heat, AHU
heating valve Vl is fully open to the AHU heating coil HX2 and valve V2
is in the normally open position. As the heating demand becomes satisfied,
valve V1 is modulated toward the by-pass position and valve V2 is modulated
open to the storage heat exchanger HX4. When valve V2 begins to open to
heat exchanger HX4, pump P2 is started, charging the 6,000-gallon water
thermal storage. After the storage temperature increases above 850F, pump
P2 runs continuously to provide DHW preheat through heat exchanger HX5.


Mode 3 Collector-to-Storage: This mode is entered when the system is
running, there is no demand for space heating, and the solar panel
temperature is greater than the storage temperature. During this mode,
valve V2 is open to heat exchanger HX4 so that collected solar energy is
delivered to storage. However, in the event that the storage temperature
is greater than the solar panel temperature, valve V2 returns to the
full by-pass position.

Mode 4 Storage-to-Space Heating: This mode is entered whenever the
solar panel temperature is below 850F, the storage temperature is greater
than 850F, and there is a demand for space heating. Since the storage
temperature is above 850F, pump P2 is operating. When the AHU controls
call for heating, pump P1 is started. If the solar panel temperature is
below 850F, valve V2 is positioned full open to heat exchanger HX4, and
valve V4 is positioned to by-pass the solar panels. Hot water from
storage is now pumped through heat exchanger HX4. Pump P1 circulates
the transport fluia through the load side of heat exchanger HX4 and the
AHU heating coil HX2 as determined by modulating valve Vl.

Mode 5 Excess Solar Heat Rejection: This mode is entered if the solar
loop temperature increases above 2000F. Valve V2 goes to the full by-
pass position and valve V3 opens to allow excess solar heat to be rejected
to the atmosphere through heat exchanger HX3. Pump P2 continues to
operate to preheat service hot water and valve V2 modulates to maintain
a maximum temperature of 2000F in the water thermal storage.










Mode 6 Domestic Water Preheat: This mode is entered whenever storage
temperature is greater than 850F. Pump P2 circulates water from storage
through hot water heat exchanger HX5.


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 operation of the Charlotte Medical Center solar energy system during
May was limited to a considerable extent by improper control system
behavior. There were several days during the month when the insolation
level was high enough to permit solar energy collection but collector
array flow was either sporadic or nonexistent. This was similar to system be-
havior in April but the opposite of the situation that occurred during March
when collector array flow often continued into the late evening hours. These
control problems have been discussed in detail in prior reports and the site
contractor is addressing the problem. Although experiencing control problems,
the system realized a small net hot water and space heating electrical energy
savings of 1.57 million Btu for the month. A total of 5.54 million Btu of
electrical operating energy was required to support the system during May.


B. Weather


J.rinj May, the measured average outside ambient temperature was 680F. This
was one degree below the long-term average ambient temperature of 690F and had








little effect on the building heating load. Long-term temperature data
are taken directly from data supplied by the National Oceanic and Atmo-
spheric Administration's Local Climatological Data Bulletin for Charlotte.

The measured value for incident insolation in the plane of the collector
array was 1,365 Btu/ft2-day, and this was 18 percent below the long-term
average of 1,674 Btu/ft2-day. However, the measured value of insolation
is in error due to a pyranometer shading problem. The pyranometer is
shaded at times during the day by the instrument that monitors wind
velocity and direction, so the actual value for measured insolation is
apparently higher than that reported. Long-term insolation in the plane
of the collector array is derived from data for Charlotte taken from the
SOLMET Volume 1 User's Manual.


C. System Thermal Performance


Collector During May, the Charlotte solar energy system collected a
net amount of 10.19 million Btu. However, approximately 0.33 million
Btu were lost by the collector array due to the erratic operation caused
by the control system. Also, an additional 0.43 million Btu were deli-
berately rejected by the heat rejection fan, and this situation was also
a direct result of the sporadic collector array operation. On bright
days, the fluid in the collector loop would exceed temperatures of 200F
during stagnation periods and this caused the heat rejection fan to come
on for short periods of time.


A total of 170.16 million Btu of incident solar energy was measured in the
plane of the collector array during May. However, as previously noted,
a net amount of only 10.19 million Btu was collected. This was due to the
limited amount of array operating time. As a result, the reported collector
array efficiency was only six percent.


Storage- During May, a total of 12.87 million Btu was delivered to storage.
Of this total, 12.83 million Btu came from the collector array, and 0.04










million Btu came from the hot water recirculation loop. The energy from the
hot water recirculation loop can be traced back to the electrical auxiliary
heaters in the DHW heater tanks. This is a system design problem which was
discussed in detail in the November 1978 report.


It should be noted that the value tabulated for solar energy delivered to
storage is greater than the value for collected solar energy. This problem
is also due to the sporadic collector array flow noted previously. The data
collection system uses a discrete measurement sampling scheme so, in all
probability, there were numerous instances when energy was being collected
in the interval between data samples, but not at the time the actual sample
occurred. Since the collector array flow was off at the time of data sampling
there would be no energy gain credited to the system for the complete sampling
period, even though some solar energy had been collected. However, as there
were no erratic flow problems in the storage loop, the solar energy collected
and transferred to the storage loop would be accounted for and this resulted
in the seeming disparity between collected and stored solar energy.


A total of 8.09 million Btu was removed from storage during the month.
However, approximately 0.33 million Btu of this energy was rejected to the
atmosphere because of the control problems.


The change in stored energy was -0.43 million Btu, and this, plus the energy
supplied to and removed from storage, resulted in a thermal loss from storage
of 5.21 million Btu. Storage was maintained at an average temperature of
120F, and the monthly storage efficiency was 0.60.


Hot Water Load The hot water load for May was 1.55 million Btu. This is
b;sed on an average supply water temperature of 740F, an average service hot
.,jter t-e.--m-rature of 1170F and an average daily consumption of 130 gallons
of -ot water. Solar energy supplied to the Kot water subsystem amounted to
6.75 -illi.ro Btu. However, because of a dt:,ign problem with the recircula-
ti.r l... in the hot water subsystem, a total of 0.04 million Btu of electri-
_- auxiliary r-r-,-rgy was delivered fromr the service hot water tanks to the









solar energy storage loop. This resulted in a net energy delivery to the hot
water subsystem of 6.71 million Btu. This design problem was discussed in
detail in the November 1978 report.


The indicated hot water solar fraction of 95 percent is based only on periods
when solar energy was being delivered to the hot water subsystem. During
periods when auxiliary energy was being delivered to the solar energy storage
loop, the hot water solar fraction was considered to be zero.


It should be noted that in spite of the design problem and erratic collector
array performance, the hot water subsystem was supported almost entirely by
the solar energy system in May.


Approximately 0.58 million Btu of auxiliary electrical energy were delivered
to the hot water subsystem. Therefore, a total of 7.33 million Btu was
actually used to support the hot water subsystem. Since the actual hot
water load was 1.55 million Btu, and 0.04 million Btu were delivered back
to the solar energy storage loop, the total losses for the hot water tanks and
recirculation loop piping amounted to 5.74 million Btu for May.


Space Heating Load The space heating load for May was 27.98 million Btu.
Solar energy supplied 0.40 million Btu of this load, which resulted in a
heating solar fraction of 2 percent. The remaining 27.52 million Btu of
energy required to support the space heating subsystem were supplied by the
supplemental baseboard electrical auxiliary system on the first floor of the
building. The main electrical auxiliary system was turned off in early April
and showed no energy consumption during May.


Although the performance of the space heating subsystem appears low for May,
it must be realized that the auxiliary energy supplied to the building heating
load was utilized entirely in the medical library area on the first floor.
This area was not designed to receive any significant support from the solar
heating subsystem even though it must be included in the total building heat-
ing load computation. Therefore, any time the main portion of the building










heating load is small (or nonexistent), the heating solar fraction will be
low if any auxiliary heat is used in the library area.


The total energy delivered to the building maintained an average interior
temperature of 710F. The average outside ambient temperature was 680F.


D. Observations


The May operation of the Charlotte Medical Center solar energy system was
somewhat contrary to the system design. The abnormal operation, in con-
junction with the control system and hot water subsystem design problems,
degraded system performance to some extent.


E. Energy Savings


During the month of May, the Charlotte solar energy system realized a net
electrical energy savings of 1.57 million Btu. The space heating subsystem
and hot water subsystem operation saved a total of 7.11 million Btu, but
this was reduced by the 5.54 million Btu of electrical energy required to
operate the system.


III. ACTION STATUS


The system problems were previously brought to the attention of the system
designer and the situation is under detailed investigation. A modification
to the present control system has been proposed and submitted to the
Marshall Space Flight Center for approval.
