4 - OPERATION
4.3.8 - Water evaporator/condenser
The evaporator/condenser is a plate heat
exchanger. The water connection of the
heat exchanger is a threaded connection.
It has a thermal insulation of 6 and 13 mm
thick polyurethane foam and includes frost
protection, as standard.
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 the manufacturer.
NOTES - Monitoring during operation:
●
Follow the regulations on monitoring
pressurised equipment.
●
It is normally required that the user
or operator sets up and maintains a
monitoring and maintenance file.
●
If there are no regulations or to
complement them follow the control
programmes of ISO 5149.
●
If they exist follow local professional
recommendations.
●
Regularly check for possible presence of
impurities (e.g. silicon grains) in the heat
exchange fluids. These impurities maybe
the cause of the wear or corrosion by
puncture.
●
The reports of periodical checks by the
user or operator must be included in the
supervision and maintenance file.
4.3.9 - Refrigerant
EREBA He units operate with refrigerant
R-410A.
4.3.10 - Receiver
EREBA He units are equipped with
mechanically welded storage tanks that
stores the excess refrigerant when the unit
operates in heating mode.
4.3.11 - Four-way valve
For EREBA He units, this device permits the
reversal of the refrigeration cycle to allow
operation in cooling mode, in heating mode,
and during defrost cycles.
4.3.12 - Inverter subassembly for
compressor and fans
The EREBA He units are fitted with Inverter
modules to control the compressor and the
fan motors.
4.3.13 - Accumulator
The EREBA He units are fitted with an
accumulator in the compressor suction line to
prevent liquid carry-over to the compressor,
particularly during defrost cycle and transient
operations.
