15.8 - Water evaporator/condenser
The evaporator/condenser is a plate heat exchanger with one or
two refrigerant circuits. The water connection of the heat exchanger
is a Victaulic connection. It has a thermal insulation of 19 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 Carrier SCS.
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 le.
• If there are no regulations or to complement them follow
the control programmes of EN 378.
• If they exist follow local professional recommendations.
• Regularly check for possible presence of impurities
(e.g. silica grains) in the heat exchange uids. 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
le.
15.9 - Refrigerant
30RQS/RQSY units operate with refrigerant R-410A.
15.10 - High-pressure safety switch
30RQS/RQSY units are equipped with automatically reset safety
pressure switches on the high-pressure side. For the alarm
acknowledgements refer to the 30RB/RQ Touch Pilot Junior control
manual).
15.11 - Storage tank
30RQS/RQSY units are equipped with mechanically welded
storage tanks that permit storing the excess charge when the unit
operates in heating mode.
15.12 - Four-way valve
This permits reversal of the cycle for operation in cooling and
heating mode and during defrost cycles.
15.13 - Control box
The control box of the 30rqs/rqsy units is equipped with electric
heaters to prevent condensation during operation at low outside
temperatures. they are installed on the top of the control box on
the outside, and are covered by a thermal insulation layer. these
heaters are switched on, based on the outside temperature.
