MONTHLY PERFORMANCE REPORT


CHESTER WEST

DECEMBER 1978


I. SYSTEM DESCRIPTION

The Chester West site is a single-family residence in Huntsville, Alabama.
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 225 square feet. The array faces south at an angle of 49
degrees to the horizontal. A glycerol-water solution is used as the medium
for delivering solar energy from the collector array to storage, and water is
the medium for delivering solar energy from storage to the space heating and
hot water loads. Solar energy is stored aboveground in a 500-gallon water
storage tank. Auxiliary space heating is provided by an air-to-air heat pump
and electrical heating elements which are designed to function in parallel
with the solar energy space heating loop. Auxiliary hot water heating is
provided in series with the solar energy hot water heating loop through the
use of electrical heating elements in an 80-gallon DHW tank. The system,
shown schematically in Figure 1, has three modes of solar operation.

Mode 1 Collector-to-Storage: This mode activates when the control system
senses a sufficient temperature difference between the collector and storage
and remains active until the temperature difference drops below the accepted
minimum. The collected energy is transferred to storage through a ring-type,
liquid-to-liquid heat exchanger located in the storage tank. Pump P1 is
operating.

Mode 2 Storage-to-Space Heating: This mode activates when there is a demand
for space heating. Solar energy is circulated to the conditioned space by
solar heated water from storage through a liquid-to-air heat exchanger located
in the air-distribution duct. Pump P3 is operating.

Mode 3 Storage-to-DHW Tank: This mode activates when the control system
senses a sufficient temperature difference between storage and the DHW tank,
and remains active as long as a sufficient difference exists. Water circu-
lates from the top of storage through a liquid-to-liquid heat exchanger
located in the bottom of the DHW tank. Pump P2 is operating.


II. PERFORMANCE EVALUATION


INTRODUCTION

The solar energy system was in continuous operation during the month of Decem-
ber. Instrumentation anomalies in the form of malfunctioning liquid flowmeters
(W300 and W400) in the storage/DHW and storage/space heating loops affected
the December analysis. It was possible to preserve the space heating perfor-
mance data by basing performance analysis on air rather than liquid flow.

This was not possible in the HIcII loiop. ',,nii. stora,:t and DHW performance
factors were rendered invalid. Data on the space heating component indicates
a solar fraction of 19 pcrceit, and an electrical energy savings of 0.55
million Btu.


WEATHER CONDITIONS

During the month, total incid,1.;t solar energy on the collector array was 8.0
million Btu for a djily av-*Jge of 1149 Btu per square foot. This wis above
the estimated average daily solar radiation for this geographical area during
December of 1066 Btu per square foot for a south-facing plane with a tilt of
49 degrees to the horizontal. The average ,imbient temperature during December
was 450F as compared with the long-term average for December of 42F.


THERMAL PERFORMANCE

Collector The total incident solar radiation on the collector array for the
month of December was 8.0 million Btu. During the period the collector loop
was operating, the total insolation amounted to 7.2 million Btu. The total
collected solar energy for the :ionth of December was 3.8 million Btu, result-
ing in a collector array efficiency of 48 percent, based on total incident
insolation. Solar energy delivered from the collector array to storage was
3.5 million Btu. Energy loss during transfer from the collector array to
storage was 0.3 million Btu.

Storage Solar energy delivered to storage from the collector was 3.5 million
Btu. The average storage temperrature for the month was 96F.

DHW Load The DHW subsystem consumed an unknown amount of solar energy and
0.46 million Btu of auxiliary electrical energy. The DHW subsystem consumed a
total of 0.18 million Btu of operating energy.

Space Heating Load The space heating subsystem consumed 1.2 million Btu of
solar energy and 5.1 million Btu of auxiliary electrical energy to satisfy a
space heating load of 6.1 million Btu. The solar fraction of this load was 19
percent. The space heating subsystem consumed a total of 0.51 million Btu of
operating energy, resulting in an electrical energy savings of 0.55 million
Btu.


OBSERVATIONS

The evaluation of the DHW and storage solar subsystems was limited by a
malfunctioning liquid flowmeter. Two system problems need correction: The
slow liquid seepage from the storage tank and the lengthy operation of the
pump in the DHW loop.


ENERGY SAVINGS

The space heating subsystem contributed an electrical savings of 0.55 million
Btu.









III. ACTION STATUS

Plans have been made to replace the storage tank. The system designer is
investigating pump operation in the DHW loop. The operation of the liquid
flow sensors are to be investigated by Boeing during the next site visit.
