HEI WAI WONG

FEBRUARY 1979


I. SYSTEM DESCRIPTION

The Hei Wai long site is a four-story multifamily housing complex in Honolulu.
Hawaii. Solar energy is used for preheating domestic hot water (DHW) and
laundry service hot water. The solar energy system comprises three distinct,
essentially identical systems, only one of which is instrumented for perform-
ance evaluation. The instrumented system supplies preheated hot water to six
apartment units and to the laundry of the housing complex. The system has an
array of flat-plate collectors with a gross area of 807 square feet. The
array faces south at an angle of 24 degrees to the horizontal. Water is the
transfer medium that delivers solar energy from the collector array to storage
and to the hot water loads. Solar energy is stored on the roof in a 1230-gallon
storage tank. When solar energy is insufficient to satisfy the hot water
loads, auxiliary water heating for each apartment is provided by electrical
heating elements in individual 30-gallon DHW tanks. Auxiliary heating of hot
water in the laundry is provided by a gas heater in the 85-gallon hot water
tank. The system, shown schematically in Figure 1, has two modes of solar
operation.

Mode 1 Collector-to-Storage: This mode activates when a sufficient teypera-
ture difference exists between the collector surface temperature and the
bottom of storage to activate a thermosiphon flow between collector and
storage. The flow continues as long as the temperature difference is great
enough to maintain the effect.

Mode 2 Storage-to-Load: This -node activates when there is a demand for hot
water replenishment from either the individual DHW tanks or the laundry tank.
The system is pressurized by the city water system.


II. PERFORMANCE EVALUATION


INTRODUCTION

The site was occupied during the month of February and the solar energy system
operated continuously during the month. Solar energy satisfied 78 percent of
the DHW requirements. The solar energy system provided electrical energy
savings of 5.8 million Btu and fossil fuel energy savings of 3.8 million Btu.


WEATHER CONDITIONS

During the month, total incident solar energy on the collector array was 30.3
million Btu for a daily average of 1342 Btu per square foot. This was below
the estimated average daily solar radiation for this geographical area during

February of 1620 Btu per square foot for a (south-facing) plane with a tilt of
24 degrees to the horizontal. The average ambient temperature during February
was 710F as compared with the long-term average for February of 720F.


THERMAL PERFORMANCE

System During February the solar energy system performed somewhat better
than expected. The expected performance was determined from a modified
f-chart analysis using measured weather and subsystem loads as inputs. Solar
energy collected was 9.2 million Btu versus an estimated 7.6 million Btu.
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 8.1 mil-
lion Btu. System total solar fraction was 78 percent versus an estimated 74
percent.

Collector The total incident solar radiation on the collector array for the
month of February was 30.3 million Btu. During the period the collector loop
was operating the total insolation amounted to 30.3 million Btu. The total
collected solar energy for the month of February was 9.2 million Btu, result-
ing in a collector array efficiency of 30 percent, based on total incident
insolation. Solar energy delivered from the collector array to storage was
9.2 million Btu. No operating energy was required by the collector loop as
this is a thermosiphon collection-to-storage subsystem.

Storage Solar energy delivered to storage was 9.2 million Btu. There were
8.1 million Btu delivered from storage to the DHW subsystem. Energy loss from
storage was 0.77 million Btu. This loss represented 8 percent of the energy
delivered to storage. The storage efficiency was 91 percent: This is calcu-
lated 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 110F.

DHW Load The DHW subsystem consumed 8.1 million Btu of solar energy and 2.2
million Btu of auxiliary electrical energy and 0.19 million Btu of fossil fuel
energy to satisfy a hot water load of 10.3 million Btu. The solar fraction of
this load was 78 percent. No operating energy was required by the DHW subsystem.
There was an electrical energy savings of 5.8 million Btu and a fossil fuel
energy savings of 3.8 million Btu. A daily average of 662 gallons of DHW was
consumed at an average temperature of 1230F delivered from the tank.


OBSERVATIONS

The solar energy system operated under a modified configuration. Since
February 1 the path of replenishment supply water was not directed to storage,
but went through the collector loop first (see Figure 1).


ENERGY SAVINGS

The solar energy system provided a total energy savings of 9.6 million Btu,
apportioned into an electrical energy savings of 5.8 million Btu and a fossil
fuel energy savings of 3.8 million Btu.
