ZEIN MECHANICAL CONTRACTORS NO. 1

OCTOBER 1978

I. SYSTEM DESCRIPTION

Zein Mechanical Contractors No. 1 is a single family residence in Milwaukee,
Wisconsin. The home has approximately 1304 square feet of conditioned space.
The solar energy system consists of two independently controlled systems: one
system serves domestic hot water (DHW) preheating, the other is used for
space heating and space cooling. Only the space heating and cooling system
is described in this report.

The system has an array of flat-plate collectors with a gross area of 384
square feet. The array faces south at an angle of 53 degrees to the hori-
zontal. Air is the transfer medium that delivers solar energy from the
collector array to storage. Solar energy is stored in a rock bin containing
41,250 pounds of rock located in the basement of the house. The rock bin
has 2 inches of polyurethane insulation on the outside walls and fiberglass
roll insulation in the ceiling. A heat pump delivers solar energy from storage
to a heat exchanger located within an air-handler. Heated air is then blown
from the air-handler to the load. When solar energy is insufficient to satisfy
the space heating load, an electric resistance heater in the air-handler
provides auxiliary energy for space heating. The system, shown schematically
in Figure 1, has 10 modes of solar operation for space conditioning.

Mode 1 Storage-to-Heat Pump-to-Space Heating: This winter mode activates
when there is a demand for space heating, the collector loop is not active,
and the outside ambient temperature is less than 100F above the rock bed
temperature. Air is drawn through motorized dampers from storage by the
collector/heat pump circulating fan, past the heat pump evaporator coil, by-
passing the collector, and returns to storage. The heat pump condenser coil
and house circulating fan supply energy to the house and electrical strip
heaters supplement the heat pump to meet the heating demand.

Mode 2 Collector-to-Storage: This winter mode activates when the tempera-
ture difference between the collector outlet and storage is 100F or higher,
and the outside ambient temperature is less than 100F above the rock bed
temperature. Air is drawn from the collector by the collector/heat pump
circulating fan and goes into the rock bin through motorized dampers and
then recirculates through the collector. There may or may not be a demand for
space heating.

Mode 3 Outside Air-to-Rock Bed: This mode activates when the collector loop
is inactive, there is no demand for space heating, and the outside ambient
temperature is higher than 100F above the rock bed temperature. Air is drawn
from the outside by the collector/heat pump circulating fan and goes into the
rock bin through motorized dampers and then exhausts to the outside through a
backdraft damper in the wall of the insulated room.

Mode 4 Outside Air-to-Heat Pump-to-Space Heating: This winter mode acti-
vates when there is a demand for space heating, the collector loop is not
active, and the outside ambient temperature is more than 10OF above the rock
bed temperature. Air is drawn from the outside through motorized dampers,
past the heat pump evaporator coil, through the storage bin, and then exhausts
to the outside through a backdraft damper in the wall of the insulated room.
The heat pump condenser coil and house circulating fan supply energy to the
house. Electric strip heaters supplement the heat pump to meet the heating
demand.

Mode 5 Outside Air-to-Collector-to-Rock Bed: This mode activates when the
difference in temperature between the collector outlet and storage is 10F or
higher, and the outside ambient temperature is more than 100F above the rock
bed temperature. Air is drawn from the outside by the collector/ heat pump
circulating fan, goes through the collector and into the rock bin through
motorized dampers, and then exhausts to the outside. There may or may not be
a demand for space heating.

Mode 6 Storage-to-Heat Pump-to-Space Cooling: This summer mode activates
when there is a demand for space cooling, the collector loop is not active,
and the rock bed temperature is less than 100F above the outside ambient
temperature. Air is drawn through motorized dampers from storage by the
collector/heat pump fan, past the heat pump condenser coil, bypassing the
collector, and returns to storage. The heat pump evaporator coil and house
circulating fan remove energy from the house.

Mode 7 Collector-to-Storage for Cooling: This mode rejects rock bed energy
by circulating air through the collector at night. This summer mode acti-
vates when the temperature difference between the rock bed and the collector
outlet is 10F or higher, and the rock bed temperature is less than 100F above
the outside ambient temperature. Air is drawn from the collector at night
by the collector/heat pump circulating fan and goes into the rock bin through
motorized dampers and then recirculates through the collector. There may or
may not be a demand for space cooling.

Mode 8 Outside Air-to-Rock Bed for Cooling: This mode activates when the
collector loop is inactive, there is no demand for space cooling, and the rock
bed temperature is more than 10F above the outside ambient temperature. Air
is drawn from the outside by the collector/heat pump circulating fan and goes
into the rock bin through motorized dampers and then exhausts to the outside
through a backdraft damper in the wall of the insulated room.

Mode 9 Outside Air-to-Heat Pump-to-Space Cooling: This summer mode acti-
vates when there is a demand for space cooling, the collector loop is not
active, and the rock bed temperature is more than 10F above the outside
ambient temperature. Air is drawn from the outside through motorized dampers
to the heat pump, past the heat pump condenser coil, through the storage bin,
and then exhausts to the outside through a backdraft damper in the wall of the
insulated room. The heat pump evaporator coil and house circulating fan
remove energy from the house to meet the cooling load.

Mode 10 Outside Air-to-Collector-to-Rock Bed: This mode activates when the
temperature difference between the rock bed and collector outlet is 10OF or






higher, and the rock bed temperature is higher than 10OF above the outside
ambient temperature. Air is drawn from the outside by by the collector/ heat
pump circulating fan, goes into the rock bin through motorized dampers, and
is then exhausted to the outside. There may or may not be a demand for space
cooling.


II. PERFORMANCE EVALUATION


INTRODUCTION

The site was unoccupied in October; however, the solar energy system operated
continuously during the month. Solar energy satisfied 49 percent of the space
heating requirements. The solar energy system incurred an electrical energy
expense of 0.16 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 1190 Btu per square foot. This was below
the estimated average daily solar radiation for this geographical area during
October of 1338 Btu per square foot for a south-facing plane with a tilt
of 53 degrees to the horizontal. The average ambient temperature during
October was 50F as compared with the long-term average for October of 510F.


THERMAL PERFORMANCE

Collector The total incident solar radiation on the collector array for the
month of October was 14.2 million Btu. During the period the collector loop
was operating the total insolation amounted to 13.7 million Btu. The total
collected solar energy for the month of October was 6.1 million Btu, result-
ing in a collector array efficiency of 43 percent, based on total incident
insolation. Solar energy delivered from the collector array to storage was
6.1 million Btu. Operating energy required by the collector loop was 0.29
million Btu.

Storage Solar energy delivered to storage was 6.1 million Btu. There were
0.23 million Btu delivered from storage to the space heating system. Energy
loss from storage was 5.8 million Btu. This loss represented 95 percent of
the energy delivered to storage. The storage efficiency was 5 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 920F.

Space Heating Load The space heating system consumed 0.23 million Btu of
solar energy and 0.25 million Btu of auxiliary electrical energy to satisfy a
space heating load of 0.48 million Btu. The solar fraction of this load was
49 percent. The space heating system consumed a total of 0.15 million Btu of
operating energy, resulting an an electrical energy savings of 0.13 million
Btu.








OBSERVATIONS

The large storage losses are attributed to leakage from the collector loop
which caused make-up air to be drawn into the insulated room through the
outside air vents.


ENERGY SAVINGS

The solar energy system provided a net electrical energy expense of 0.16
million Btu. The space heating system contributed an electrical energy
savings of 0.13 million Btu.


III. ACTION STATUS

No action is planned.
