Technical Features (continued)
The drain pan is equipped with an electric heater (RE) to melt
the ice during the defrost cycle.
One refrigerant pressure transducer (TPH) monitors the pressure
in the outdoor coil (on heating and cooling mode). It opens (or
closes) the auxiliary outdoor air dampers (D4) to allow more (or
less) outdoor air to mix with the exhaust air before the outdoor
coil. This function insures a safe and efficient operation of the
heat-pump.
The indoor coil (BEV) allows for high dehumidification on
cooling mode.
The drain pan under the indoor coil is with positive slope,
removable for hygienic cleaning.
Most brazing, fittings and refrigerant devices are assembled in
the technical compartment to ease service without disturbing
the operation of the RT4D.
Each refrigerant circuit is equipped with 3 pressure switches to
protect the machine :
- High pressure switch with automatic reset (pre-alarm),
- High pressure switch with manual reset,
- Low pressure switch with manual reset.
On very hot summer days, the tandem Compressors avoids a
total cooling cut-out. A refrigerant high-pressure safety valve
(SV) is located on the liquid receiver.
One compressor can be equipped with optional inverter (to be
used with reciprocating compressor) to modulate the heating or
cooling capacity from sizes 20 to 180.
A G4 air filter protects the outdoor-coil.
