MONTHLY PERFORMANCE REPORT


HOMES BY MARILYNN

APRIL 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 850F.


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 1350F,
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 April, except for the period from April 14 to April 21.
The solar energy system operated continuously during the month. Solar energy
satisfied 70 percent of the DhW. requirements and 53 percent of the space
heating requirements. The solar energy system provided an electrical energy
savings of 0.33 million Btu. Space heating was not required after April 16.
The auxiliary heating element in the DHW loop burned out on April 20; there-
fore, the solar energy system provided DHW heating for the rest of the month.



WEATHER CONDITIONS


During the month, total incident solar energy on the collector array was
16.5 million Btu for a daily average of 1777 Btu per square foot. This was
below the estimated average daily solar radiation for this geographical area
during April of 2003 Btu per square foot for a south-facing plane with a tilt
of 55 degrees to the horizontal. The average ambient temperature during April


4251








I..I'. 53F as compared with the long-term average for April of 560F. The
number of heating degree-days for the month (based on a 650F reference) was
(0, as i i'ip.red with the long-terml average of 282. The number of cooling
degr,-i'-days was 9, as coilllpred with the average of 6. The ambient tempera-
ture sensor (T001) provided erroneous readouts intermittently during the
iunth. The affect on the average temperature reading above is not able to be
determined; however, another solar installation in the Albuquerque area
;.iL',.sured an average ambient temperature of 57F.



T HLEP .MAL PERFORMANCE



Collector The total incident solar radiation on the collector array for the
month of April was 16.5 million Btu. During the period the collector loop
..:s operating, the total insolation amounted to 11.4 million Btu. The total
collectul solar energy for the month of April was 3.7 million Btu, resulting
in a collector array efficiency of 23 percent, based on total incident insola-
tion. Solar energy delivered from the collector array to storage was 4.1
million Btu.


The apparent 0.4 million Btu gain in solar energy delivered to storage over
- ,'..,unt collected is an obvious impossibility. The flow rates measured by
sensors .,'100 and W200 should remain constant throughout a period of contin-
Sus collection, but the rates varied by as much as 15 percent throughout the
rnth. The source of this variation has not been determined. However,
,ti.,tial sources are: an erroneous ir,-Lasurement capability through the flow
s.'sors, actual flow variance caused by the collector pump, and/or inconsis-
tent operation of values Vl and V2. On April 20 a much higher rate variation
b .-n to -cur through W100. As much as a 50 to 60 percent difference occurred
by the end of the .vnth. etherhr the condition is the result of a new failure
or d. ra tion of the earlier problem has not been determined. An investi-
tion is continuing in order to locate and correct the cause of the collector-
to-s' r -( i balance.









There was 0.54 million Btu of operating energy required by the collector loop
during April.


Storage Solar energy delivered to storage was 4.1 million Btu. There were
1.7 million Btu delivered from storage to the DHW and space heating subsystems.
Energy loss from storage was 2.2 million Btu. This loss represented 54 per-
cent of the energy delivered to storage. The storage efficiency was 46 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 1350F.


DHW Load The DHW subsystem consumed 0.80 million Btu of solar energy and
0.58 million Btu of auxiliary electrical energy to satisfy a hot water load
of 0.99 million Btu. The solar fraction of this load was 70 percent. Losses
from the DHW subsystem were 0.40 million Btu. The DHW subsystem consumed a
total of 0.23 million Btu of operating energy, resulting in an electrical
energy savings of 0.48 million Btu. A daily average of 63 gallons of DHW was
consumed at an average temperature of 1330F delivered from the tank. There
was no hot water required during the homeowners absence between April 14 and
April 21. Or April 20 the heating element in the hot water tank burned out.
All hot water used for the rest of the month was heated by solar energy.


Space Heating Load The space heating requirement for April was 1.6 million
Btu, all of which occurred prior to April 16. The solar energy system pro-
vided 0.88 million Btu or 53 percent of this requirement. The remaining load
of 0.77 million Btu was satisfied by an auxiliary electrical heat pump and an
electrical heating element at an electrical consumption of 0.29 million Btu.
The space heating subsystem consumed an additional 0.22 million Btu of oper-
ating energy. A net electrical energy savings of 0.40 million Btu was ob-
tained by the solar portion of the space heating subsystem.

O. ,E...'AT I( i.


T',. space heating subsysteml is desi(gnerd to utilize solar energy as long as
th, stora j t"impL.rature is higher than 850F. Measurements of storage indi-
cate that the use of solar energy for space heating terminates when the
storai'. temperature decreases to 1050F. The continuous cycling DHW preheat
1 ., continues to extract energy from storage as long as there is a demand
in the DHW preheat tank. Storage must be reheated in order to replace the
storage losses and the energy used by the DHW preheat before space heating
by the solar energy system can be accomplished.


In order to heat the house, mode 4 and mode 5 require the use of the heat
..:, 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 0.33
million Btu. The DHW subsystem provided an electrical energy savings of
0.48 million Btu and the space heating subsystem provided an electrical
energy savings of 0.40 million Btu. The collection and storage subsystem
incurred an electrical energy expense of 0.55 million Btu.



III. ACTION STATUS


Varying flow rates through the collector flow rate sensor (W100) are affecting
the energy collection calculation. An investigation is continuing to deter-
mine whether the n.asurement sensor or an erratic flow is the cause.









The temperature sensor that measures the inside ambient temperature was
insulated on April 7 by the grantee to eliminate the affect of heat from the
solar energy equipment room.


Boeing is planning to replace the temperature sensor (T1001) that measures
the outside ambient temperature.


The grantee is planning to replace the DHW heating element in May.


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