2.2
Description
of
the
TCU
40/80
The
TCU
40/80
is
a
single-channel
temperature
control
unit
engineered
for
temperature
control
of
remote
heat
loads.
From
distances
up
to
SO
feet,
the
TCU
40/80
can
cool
the
heat
load
generated
by
the
process
equipment.
The
coolant
circulates
through
the
TCU
40/80,
where
it
is
cooled
or
heated
as
required,
then
is
transferred
to
the
process
equipment,
and
returns
in
a closed
loop.
The
TCU
40/80
maintains
supply
coolant
at
a
temperature
between
-40
°C
and
+80
°C,
selectable
in
0.1
°C
increments,
with
a
tolerance
of
±1.0
°C.
2.3
Lockout
procedure
To
prevent
accidental
or
unauthorized
starting
of
the
TCU
40/80
during
maintenance,
disconnect
the
power
cord
from
the
receptacle
and
install
an
appropriate
lock-out
device
(Hubbell
Small
Plugout™
or
equivalent)
on
the
end
of
the
power
cord.

Refrigeration
(see
figure

above)
1.
Refrigerant
gas
enters
the
compressor
at
low
temperature
and
pressure.
It
leaves the
compressor
at
high
pressure
and
temperature.
2.
The
gas
passes
into
the
condenser,
where
heat
is
removed
by
the
external
water
supply,
causing
the
gas
to
condense
into
a
liquid.
3.
The
cool
liquid
refrigerant
exits
the
condenser
and
passes
through
a
filter
dryer
that
removes
any
residual
moisture
or
contaminants.
4.2.1
If
cooling
is
required:
1.
Solenoid
valve
SV1
opens
(coil
energized),
allowing
the
refrigerant
to
flow
into
the
Thermostatic
Expansion
Valve
(TEV).
The
pressure
drop
across
the
TEV
causes
the
refrigerant
to
change
from
a
liquid
to
a
mixture
of
liquid
and
gas.
2.
The
liquid
and
gas
mixture
enters
the
heat
exchanger
where
it
becomes
entirely
a
gas.
The
process
of
expansion
from
a
liquid
to
a
gas
reduces
the
temperature
by
absorbing
energy.
3.
The
refrigerant
leaving
the
heat
exchanger
returns
to
the
compressor
through
the
subcooler
and
a
crankcase
pressure
regulator.
The
subcoolcr
further
cools
the
refrigerant
entering
the
TEV.
TCU

Temperature
Control
Unit
4.2.2
If
cooling
is
not
required:
1.
Solenoid
valve
SVl
closes
(coil
de-energized).
2.
Hot
refrigerant
from
the
compressor
is
passed
through
SV2
(coil
energized)
and
a
hot
gas
bypass
valve
before
returning
to
the
compressor
suction
line.
This
bypassing
allows
the
compressor
to
run
continuously.
3.
Cooling,
required
to
prevent
the
compressor
from
overheating,
is
provided
by
allowing
some
of
the
liquid
from
the
condenser
to
pass
through
the
safety
cooling
automatic
expansion
valve
into
the
suction
line,
thus
maintaining
the
discharge
gas
temperature
below
99
°C.
4.3
Coolant
circuit
Coolant
is
pulled
from
the
reservoir
by
the
circulation
pump
and
transferred
to
the
heat
exchanger
where
it
is
cooled
by
the
refrigeration
system
as
required.
It
then
flows
to
the
process
equipment
by
means
of
the
coolant
supply
hose.
The
coolant
returns
to
the
TCU
40/80
reservoir
by
means
of
the
coolant
return
hose.
The
coolant
system
requires
8
liters
of
coolant
for
the
reservoir,
plus
the
volume
of
the
circulation
lines
and
any
other
spaces
filled
with
coolant
that
are
attached
to
the
TCU
40/80.
To
increase
the
coolant
temperature,
the
reservoir
uses
an
electrical
resistance
heater
that
is
controlled
by
the
temperature
controller.
The
heater
must
be
fully
submerged
at
all
times,
and
if
the
coolant
in
the
reservoir
falls
below
3.S
liters,
a
level
switch causes
the
status
alarm
signal
to
automatically
shut
down
the
TCU
40/80.
A
three-float
level
switch,
a
thermostat,
and
a
flow
sensor
provide
coolant
status
signals
to
the
TCU
40/80
control
system.
4.4
Temperature
monitoring
A
Resistance
Temperature
Device
(RTD)
monitors
the
temperature
of
the
coolant
leaving
the
TCU
40/80
and
transmits
this
information
to
the
temperature
controller.
The
TCU
40/80
compares
the
output
of
the
RTD
to
the
selected
process
temperature
(SVl)
and
determines
if
the
coolant
needs
to
be
cooled
or
heated.
The
temperature
controller
then
operates
the
main
cooling
solenoid
valve
or
heater.
The
coolant
temperature
at
the
supply
port
on
the
rear
panel
is
measured
by
a
local,
internally
connected
RTD.
If
sensing
of
process
equipment
temperature
is
needed,
connect
an
RTD
to
J72J3
at
the
rear
panel
(see
Figure

you
must
warn
your
supplier
if
the
substances
you
used
(and
produced)
in
the
equipment
can
be
dangerous.
You
must
do
this
to
comply
with
health
and
safety
at
work
laws.
You
must
complete
the
Declaration
(HS2)
on

it
has
only
been
used
with
substances
that
are
not
dangerous.
Your
equipment
is
'contaminated'
if
it
has
been
used
with
any
dangerous
substances.
•
If

for
two
years
caused
an

pathological
changes
in
the
