11 - MAJOR SYSTEM COMPONENTS
11.1 - Compressors
TD units use hermetic scroll compressors with vapour injection.
Each compressor is equipped with a crankcase oil heater, as
standard.
Each compressor function is equipped with:
-
Anti-vibration mountings between the unit chassis and the
compressor(s).
-
A single pressure safety switch at the discharge.
11.2 - Lubricant
The compressors installed in these units have a specific oil
charge, indicated on the name plate of each compressor.
The oil level check must be done with the unit switched off, when
then suction and discharge pressures are equalised. The oil level
must be visible and above the middle of the sight-glass in the oil
equalisation line. If this is not the case, there may be an oil leak
in the circuit. Search and repair the leak, then recharge oil, so
that it reaches a level between the middle and three quarters of
the sight-glass (unit in vacuum).
Too much oil in the circuit can cause a unit defect.
Use only oils which have been approved for the
compressors. Never use oils which have been
exposed to air. R-22 oils are absolutely not
compatible with R-407C oils and vice versa.
11.3 - Air evaporators
The TD coils are air evaporators with internally grooved copper
tubes with aluminium fins.
11.4 - Fans
Axial Flying Bird fans equipped with a rotating shroud and made
of composite recyclable material. The motors are three-phase,
with permanently lubricated bearings and insulation class F. See
table below.
According to the Regulation No. 327/2011 implementing Directive
2009/125/EC with regard to ecodesign requirements for fans
driven by motors with an electric input power between 125 W
and 500 kW.

Above data for fans and motors, which are mandatory regarding
eco-design regulation, are provided for a stand-alone component
(not included in the chiller system).
11.5 - Electronic expansion valve (EXV) of
the main circuit
The EXV is equipped with a stepper motor that is con-trolled via
the EXV board.
11.6 - Electronic expansion valve (EXV) of
the economised circuit
The EXV is equipped with a stepper motor that is con-trolled via
the EXV board.
11.7 - Four-way valve
The four-way valve allows the reversal of the refrigerant cycle,
required during the unit defrost phases.
11.8 - Moisture indicator
Located on the liquid line, permits control of the unit charge and
indicates moisture in the circuit. The presence of bubbles in the
sight-glass indicates an insufficient charge or non-condensables
in the system. The presence of moisture changes the colour of
the indicator paper in the sight-glass.
11.9 - Filter drier
One-piece, brazed filter drier, located in the liquid line. The filter
drier keeps the circuit clean and moisture-free.The moisture
indicator shows when the filter drier to be changed. A difference
in temperature between the filter inlet and outlet shows that the
element is dirty.
According to the Regulation No. 640/2009 and amendment
4/2014 implementing Directive 2009/125/EC with regard to
ecodesign requirements for electric motors.
