Hi-Velocity 30180200001 Bi-Flow Add-on for Heat Pump Applications
1 or 2-stage 16 SEER+ Units
Inverter Variable Speed Heat Pumps Don't Need This
The Bi-Flow
Receiver is designed for use with heat pump systems, up to 5
tons and with any typical refrigerants. The receiver allows refrigerant
a location to migrate to during the heating cycle, minimizing head pressures.
During cooling mode, the receiver is empty, allowing the full refrigerant
charge to be utilized for cooling. Single and two stage models,
otherwise in heating mode they can shut off due to high pressure.
The
receiver is a horizontal tank with a pair of dip tubes extending
to the bottom of the tank. These two tubes allow for liquid
refrigerant to be drawn from the tank regardless of the direction
of flow. For this reason, the receiver must be mounted so that
the inlet/outlets of the tank come out of the top of the unit.
Mounting brackets are located at the base of the unit for secure
mounting. The receiver is to be located on the liquid line of the
system, anywhere between the indoor and outdoor coils. As the unit
is of a bi-flow design, it does not matter which end faces towards
the indoor coil.
The
inlet/outlet ports are constructed of steel and require the use of a
35-45% Silver Solder and Flux for brazing. The use of standard
copper to copper solders may result in difficulty brazing and the
potential for a failure at the weld. Ensure that the tank is protected
from overheating while brazing and that any remaining flux is
cleaned from the unit. If installing outdoors, ensure that the receiver
is insulated and protected from the elements.

on both, the inlet/outlet ports are constructed of steel and require
the use of a 35-45% Silver Solder and Flux for brazing.
