INTRODUCTION TO
ECONAR HEAT
PUMPS
ECONAR Energy Systems,
Corp.
has
been
producing
geothermal
heat
pumps in Minnesota
for over
flfteen
years.
The cold
winter climate
has
driven the design
of
ECONAR
Energy System's
heating
and
cooling
equipment
to what is
known
as
a
"Cold Climate"
geothermal
heat
pump.
This
cold climate technology
focuses
on
maximizing the
energy savings available
in
heating dominated regions
without sacrificing
comfort.
Extremely efficient
cooling, dehumidification
and
optional domestic hot water heating are also
provided
in
one
neatly
packaged system.
Geothermal
heat
pumps get their name
from the ffansfer
of
heat to and
from
the
earth. The earth
coupled heat
exchanger (geothermal
loop)
supplies
the source
energy
for heating
and absorbs the
discharged energy
from
cooling.
The system uses
a
compression cycle, much
like
your refrigerator, to collect the earth's
energy supplied
by
the sun and uses
it
to heat
your home. Since ttte process
only
moves heat and does
not
create
it,
the
efficiencies are
three
to
four times higher than the
most
efficient fossil
fuel
systems"
This guide discusses the
GeoSource
Invision3 series heat
pumps that
are
equipped
with
a
dual compressor
configuration to supply
multiple
stages
of heating, cooling
and
hot water combinations"
GeoSource
Invision3 heat
pumps
are
specifically
designed
for
domestic hot water
heating applications where
a
double walled, water cooled
condenser
coil is
used
to
safely heat
all of
a
family's hot
water
needs.
Safety and
comfort
are
both inherent to, and designed
into
ECONAR Energy System's
geothermal
heat pumps.
Since the system
runs completely on
electrical energy,
your entire home
can have
the safety
of being gas
free.
"
The best engineering
and
quality control is
built into
every
ECONAR
heat
pump
built.
Proper application and
correct
installation
will
assure
excellent performance
and
customer satisfaction.
ECONAR's commitment to
quality is written on the side
of every heat
pump
we
build.
Throughout
the
building
process the
technicians that build each
unit
sign
their
names
to the
quality
assurance
label after completing
their
inspections. As
a
fina1
quality
test,
every
unit
goes
through
a
fulI
run test
where the
performance and
operation
is
verified in
the
heating,
cooling,
and
hot
water
modes. No other manufacturer
goes
as
far
as
to run
a
full
performance check to assure system
quality.
,6S
IMPORTANT**
Service
of refrigerant
based
equipment
can be hazardous
due
to
system
pressure
and
23O
volt
electrical energy.
Only trained
or qualified service personnel can
install,
repair or service
refrigerant equipment.

Warning:
Turn
off
the
main switches before
performing service or maintenance to this
unit. Electrical
shock can
cause
personal
injury.
The
installer
is
responsible
to
see
that
all local electrical,
plumbing,
heating
and
air
conditioning codes
are
followed.

INVISION3
FEATURES
The GeoSource
Invision3 is ECONAR's
most
advanced
geothermal
heat
pump.
The design
of this
system
took
into account issues such as
environmental impact,
power
supply efficiency,
cold climate home
construction, and
global energy
trends. This unit
offers unique
and
innovative features to
optimize
the
efficiency, comfort
and
reliability of
a
home space
conditioning system.
The GeoSource
Invision3 is available
in four
configurations:

with

-SUP
The
frst
two models take
advantage
of typical heating
and
cooling
cold climate load
profiles.
In cold climate
applications, more
he-ating
is
required than
cooling' The
GeoSource
Invisionr provides two heating
stages
to meet
the
higher heating load and one
cooling stage.
In heating
mode,
the second stage
is shared befween the
building's
heating
and the
hot water heating needs. The
second
stage
in
cooing then becomes
available
for domestic
hot
water heating.
The hot water can be used
exclusively for DHW
needs
or,
ifplumbed
properly per local code, can be used to
provide
radiant
floor
heating. The
-DWR unit provides
additional
heat
to the 2'd stage
ofheating. This additional
heat
is
beneficial to
both forced air
and
hot water
loads,
especially when radiant
floor heating is part of
the system"
The last two
are
forced air heating
and
cooling only where
one has a
desuperheater and
are
best
applied ia
applications
requiring
high cooling or
dehumidification
capacities. The desuperheater
provides supplemental
hot
water
in heating
and
cooling,
tp
to
65Vo
of
a
homes
domestic hot water needs, and takes advantage
offree
heat
available whenever
cooling
is
in
operation.
