OPERATION

“B” Type
Normal (Outdoor) Condenser - De-en er gized

See Figure 1. With the pilot valve de-energized, high side
pressure is pre vent ed from entering the cavity above the
piston assembly. At the same time, the upper pilot port is
open to suction pressure. The re sult ing pressure differential
across the piston moves the piston-seat assembly to close
the reclaim condenser port (up per main port). In this mode,
the refrigerant flows to the normal condenser. The pilot valve
opens the cavity above the piston to suction. This allows the
reclaim condenser to be pumped out through a small bleed
hole in the piston. The pump out process reduces the reclaim
condenser to suction pressure. Once suction pressure is
reached, the flow through the bleed hole in the piston stops.
There is no high to low side bleed with continued operation in
the normal condenser mode. For a more efficient pump out
of the reclaim condenser, a normally open solenoid valve can
be added to the lowest physical location of the reclaim coil to
remove liquid.

Suction

upper pilot port is closed to suction. High side pressure build
up on top of the piston moves the piston-seat assembly to
close the normal con dens er port and open the reclaim (upper)
main port. With the upper pilot port closed, there is no high to
low side bleed and resulting ca pac i ty loss with the system in
the reclaim mode.

Valves using the MKC-1 coil may be used on fluids or gases
where the temperature does not exceed 240°F (116°C), while
the valve ambient is 120°F (49°C). The coil is Underwriters
Laboratory Class F rated.

INSTALLATION

Piping Suggestions

Valves must be installed in a horizontal or vertical position
with the coil level with or above the valve body. Install Heat
Reclaim Valves so the con nec tions are in the proper flow
direction as shown in Figure 2.

With the pilot valve de-energized, high side pressure is

Figure 3 shows piping schematics only to illustrate the general
in stal la tion of the Heat Reclaim Valves. Sporlan recommends
that rec og nized piping references be consulted for assistance
in piping pro ce dures. Sporlan is not responsible for system
design, any damage resulting from system design, or for mis­application of its products.

Proper support of heat reclaim valves is essential. Concentrated
stresses resulting from thermal expansion or compressor
vibrations can cause fatigue failure of tubing, elbows and valve
fittings. Fatigue failures can also result from vapor propelled
liquid slugging, and condensation induced shock. The use
of piping brackets close to each of the 3-Way valve fittings is
recommended.

HEAD PRESSURE CONTROL FOR
RECLAIM SYSTEMS

When employing heat reclaim on a refrigeration system, the addi­tion of head pressure controls is important not only to maintain
liquid pressure at the expansion valve inlet, but also to assure the
avail abil i ty of quality hot gas at the reclaim heat exchanger.

See Sporlan Bulletin 90-30, Head Pressure Control Valves for
high and low ambient stability. When low ambient con di­tions are encountered during fall-winter-spring operation, the
Sporlan head pressure controls hold back liquid refrigerant so
a portion of the condenser surface is inactive. This results in a
rise in condensing pressure.

NOTE: To calculate additional charge required for head
pres sure control, see Bulletin 30-20, or Bulletin 90-30-1.

may eliminate need of cap tube or Sporlan Restrictor

T Proper support of heat reclaim valves is essential.

Concentrated stresses resulting from thermal expan­sion or compressor vibrations can cause fatigue
failure of tubing, elbows and valve fittings. Fatigue
failures can also result from vapor propelled liquid
slugging, and condensation induced shock. The use
of piping brackets close to each of the three way
valve fittings is recommended.

TYPICAL WIRING SCHEMATICS & ELECTRICAL CONSIDERATIONS

Single Compressor Systems

Wiring of single compressor units may require the use of
relays to prevent high to low side bleed during periods
when the compressor is not circulating refrigerant. This is
necessary to prevent refrigerant migration to the low side of
the system where it may condense into liquid and damage
system components when the compressor restarts.

It is always a good idea to check with the equipment man­ufacturer for recommendations on the application of heat
reclaim on the specific type of equipment. It is necessary
to adhere to local piping and electrical codes that apply to
each application. For complete product information, refer
to Bulletin 30-20.

SERVICE

Typical Malfunctions

There are only three possible malfunctions: 1. Coil
burnout. 2. Failure to shift to Reclaim Mode. 3. Failure
to shift to Normal Mode. Each is discussed below:

COIL BURNOUT

Coil burnouts are extremely rare unless caused by one of the
following:

1. Improper electrical characteristics.

2. Continuous over-voltage, more than 10%.

3. Under-voltage of more than 15%. This applies only if the
op er at ing conditions are such that the reduced MOPD
causes stalling of the plunger, which results in excessive
current draw.

4. Incomplete magnetic circuit due to the omis sion of the

plunger assembly during reassembly.

5. Mechanical interference with movement of plunger which
may be caused by a deformed enclosing tube.

6. Coil energized while not installed on a valve.

FAILURE TO SHIFT TO RECLAIM MODE

1. Coil burnout (see coil burnout at left).

2. MOPD greater than specifications.

3. Restricted high pressure pilot connection.

4. May not have allowed sufficient time to pump out the
reclaim coil while in the normal mode.

FAILURE TO SHIFT TO NORMAL MODE

1. Stray voltage holding plunger up.

2. Restricted, closed service valve, or capped suction connec­tion on pilot.
