11 - MAJOR SYSTEM COMPONENTS AND OPERATION DATA
The water connection of the heat exchanger is a Victaulic
connection. As an option the evaporator is available with frost
protection (evaporator frost protection option).
The products that may be added for thermal insulation of the
containers during the water piping connection procedure must
be chemically neutral in relation to the materials and coatings to
which they are applied. This is also the case for the products
originally supplied by CIAT.
11.2.2 - Oil separator
In these units, the oil separator is a pressure vessel that is
mounted under the outside vertical condenser coils. Dis-charge
gas at the compressor outlet is directed towards the bottom of
the oil separator ring and most of the oil separates from the gas
by strong deceleration and by gravity. The gas then flows through
a wire mesh screen where the remaining oil is separated by
coalescence and flows to the bottom of the ring. The gas is now
free from oil and leaves the ring at the top towards the condenser.
The oil separator is equipped with a trace heater regulated by
the control.
11.2.3 - Economiser function
The economiser function includes a liquid duct valve,
a dehumidifier filter, two electronic expansion valves (EXV),
a plate heat exchanger, and protection devices (valve).
At the condenser outlet a part of the liquid is expanded via the
secondary EXV in one of the heat exchanger circuits and then
returns as gas at the compressor economiser. This expansion
permits increase of the liquid sub-cooling of the rest of the
flow that penetrates the evaporator via the principal EXV. This
permits increasing the cooling capacity of the system as well as
its efficiency.
11.3 - High-pressure safety pressostat
LX units are equipped with high-pressure safety pressostats.
In accordance with the applicable code the high-pressure
switches with manual reset, called PZH (former DBK), may be
backed up by high-pressure switches that require resetting with
a tool. The high-pressure switches that require resetting with a
tool are called PZHH (former SDBK). If a PZHH cuts out, the
corresponding PZH in the same compressor is faulty and must
be replaced. The PZHH must be reset with a blunt tool with a
diameter of less than 6 mm. Insert this tool into the opening on
the pressure switch and push the reset button in this location.
These pressure switches are located at the discharge of each
compressor.
11.4 - Condensers
The coils in LX units are all-aluminium micro-channel condensers.
11.5 - Fans
The fans are axial Flying Bird fans equipped with rotating shroud
and made of composite recyclable material. Each motor is fixed
with transverse supports. The motors are three-phase, with
permanently lubricated bearings and insulation class F
(level IP55).
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.
