HOMES BY MARILYNN

JUNE 1979

I. SYSTEM DESCRIPTION


The Homes by Marilynn site is a single-family residence in Albuquerque,
New Mexico. 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 335 square feet. The array faces south at an
angle of 55 degrees to the horizontal. A mixture of 35 percent ethylene
glycol and 65 percent water is the transfer medium that delivers solar energy
from the collector array to a liquid-to-liquid heat exchanger in the storage
loop. It also delivers solar energy to a liquid-to-air heat exchanger in the
space heating subsystem in order to preheat outside air for the heat pump.
Solar energy is stored underground in a 1000-gallon water storage tank. The
city supply water is preheated by continuously circulating water from a
preheat tank through a heat exchanger in the storage tank. Preheated city
water is stored in a 30-gallon preheat storage tank and supplied, on demand,
to a conventional 40-gallon DHW tank. When solar energy is insufficient to
satisfy the space heating load, a heat pump and an electrical heating element
in the air-handling unit provide 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 five modes
of solar operation.


Mode 1 Collector-to-Storage: This mode activates when the temperature
at the top of the collector is 100F higher than the temperature in storage.


Mode 2 Storage-to-Space Heating: This mode activates when there is a
demand for space heating and the storage temperature is higher than 85F.


Mode 3 Storage-to-DHW Tank: This mode is active at all times with water
continuously circulating between the DHW preheat tank and the storage tank.

Mode 4 Collector-to-Storage and Heat Pump Assist: This mode activates when
the conditions for mode 1 are satisfied, there is a demand for heat pump
assistance for space heating, and the temperature of storage is higher than
1350F. During this mode, the outside air that is transferred across the heat
pump coil is preheated.


Mode 5 Storage-to-Preheat Assist: This mode activates when there is no
flow through the collector, the temperature of storage is higher than 135F,
and a demand for heat pump assistance for space heating exists. The collector
loop heat exchanger obtains energy from storage to preheat the outside air
that is transferred across the heat pump coil.



II. PERFORMANCE EVALUATION



INTRODUCTION


The site was occupied in June and the solar energy system operated continuously
during the month. Total solar energy collected was 3.0 million Btu and the
amount of solar energy used was 1.3 million Btu or 42 percent of the collected
energy. The change in stored energy was 0.073 million Btu and the total
system losses amounted to 1.7 million Btu. Solar energy satisfied 76 percent
of the DHW requirements. There was no space heating requirement during the
month. The solar energy system provided an electrical energy savings of 0.15
million Btu.



WEATHER CONDITIONS


During the month, total incident solar energy on the collector array was
14.2 million Btu for a daily average of 1526 Btu per square foot. This was
below the estimated average daily solar radiation for this geographical area
during June of 1774 Btu per square foot for a south-facing plane with a tilt








of 55 degrees to the horizontal. The average ambient temperature during June
was 730F as compared with the long-term average for June of 750F. The number
of heating degree-days for the month (based on a 650F reference) was 24, as
compared with the long-term average of zero. The number of cooling degree-
days was 264, as compared with the long-term average of 291.


The ambient temperature sensor (TOO1) provided erroneous values intermit-
tently during the month. The affect on the average temperature reading
appears to be negligible: the average ambient temperature measured at
another solar installation in this geographical area was also 73F. The
average daytime ambient, however, (measured from the three hours before
solar noon until three hours following solar noon) was 90F higher at the
Homes by Marilynn site when compared to the other installation.



THERMAL PERFORMANCE


System During June 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 1.3 million Btu versus
an estimated 1.6 million Btu. System total solar fraction was 76 percent
versus an estimated 100 percent.


Collector The total incident solar radiation on the collector array for the
month of June was 14.2 million Btu. During the period the collector loop was
operating, the total insolation amounted to 10.7 million Btu. The total
collected solar energy for the month of June was 3.0 million Btu, resulting
in a collector array efficiency of 21 percent, based on total incident insola-
tion. Solar energy delivered from the collector array to storage was 3.4 million
Btu.


The apparent 0.4 million Btu gain in solar energy delivered to storage over
the amount collected is an obvious impossibility. The flow rates measured by









sensors W100 and W200 should remain constant throughout a period of continuous
collection. A variation of 15 to 20 percent, however, was measured on sensor
W100. The source of this variation has not been determined. Potential
sources are: an erroneous measurement capability through the flow sensors,
actual flow variance caused by the collector pump, and/or inconsistent opera-
tion of valves V1 and V2.


Storage Solar energy delivered to storage was 3.4 million Btu. There were
1.3 million Btu delivered from storage to the DHW subsystem. Energy loss
from storage was 2.0 million Btu. This loss represented 60 percent of the
energy delivered to storage. The storage efficiency was 40 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 1420F.


DHW Load The DHW subsystem consumed 1.3 million Btu of solar energy and
0.32 million Btu of auxiliary electrical energy to satisfy a hot water load
of 1.1 million Btu. The solar fraction of this load was 76 percent. Losses
from the DHW subsystem were 0.46 million Btu. The DHW subsystem consumed a
total of 0.23 million Btu of operating energy, resulting in an electrical
energy savings of 0.77 million Btu. A daily average of 85 gallons of DHW was
consumed at an average temperature of 1280F delivered from the tank.


Space Heating Load There was no space heating required during June.



OBSERVATIONS


The effectiveness of the solar energy system in June was limited by the
combination of large hot water utilization during short periods in conjunc-
tion with a relatively small (30-gallon) DHW preheat tank. Electrical energy
is frequently required to heat the water in the DHW tank to satisfy the
thermostat setting. This is because the replenishment water from the preheat
tank does not always have enough time to be heated from the stored solar
energy prior to the next hot water demand.









The solar system provided 1.3 million Btu of solar energy to the system
loads. Operation of the solar energy system equipment consumed 65 percent
(0.85 million Btu) of that amount in electrical energy while collecting and
distributing solar energy.


The space heating subsystem is designed to utilize solar energy as long as
the storage temperature is higher than 850F. Measurements of storage indi-
cate that the use of solar energy for space heating terminates when the
storage temperature decreases to 1050F. The constantly cycling DHW preheat
loop continues to extract energy from storage as long as there is a demand in
the DHW preheat tank. Storage must then be reheated to 1050F in order to
replace the storage losses and the energy used by the DHW preheat. Then
solar energy space heating can be accomplished.


In order to heat the house, mode 4 and mode 5 require the use of the heat
pump and a storage temperature of at least 1350F. The heat pump is only used
to heat the house upon a second-stage thermostat heating requirement (house
temperature is "n" degrees less than the thermostat setting). The only time
that these criteria can be met is when mode 2 is not functioning. Since the
valves and flow rate in the collector loop are potential sources of the
imbalance in energy calculations, elimination of the heat pump assist functions
may be worth considering.



ENERGY SAVINGS


The solar energy system provided a net electrical energy savings of 0.15
million Btu. The DHW subsystem provided an electrical energy savings of
0.77 million Btu. The collection and storage subsystems incurred an elec-
trical energy expense of 0.62 million Btu.



III. ACTION STATUS


Flow rate variance through the collector flow rate sensor (W100) is affecting
the energy collection calculation. An investigation is continuing to determine








whether the measurement sensor or an erratic flow is the cause. Elimination
of the heat pump assist loop is being considered by the grantee and Boeing.


Boeing is planning to replace the temperature sensor (T100) that measures the
outside ambient temperature.


The grantee is evaluating whether the deactivation of the solar portion of
the space heating subsystem is acceptable at a 1050F storage temperature or
whether it should be corrected to operate in the 850F design level.
