Nominal cooling capacity 16.7-29 kW
Nominal heating capacity 18.8-34 kW
This new generation of air-to-water heat pumps features the
latest technological innovations, incorporating scroll
compressors and operating on the ecological refrigerant
HFC-407C.
The 30RH heat pumps from Carrier have an integrated
hydronic module, with pump and expansion tank, limiting
the installation to simple operations like connection of the
power supply and the water supply and return piping.
An auto-adaptive control system ensures intelligent control
of the compressor start-up sequence.
Features
n
Refrigerant R-407C is a blend of R-32, R-125 and R-134a,
ensures similar performances to those achieved with R-22
and offers an economical solution to environmental protection problems. It has no effect on the ozone layer and can
be used as a replacement for R-22 in air conditioning applications with small and medium capacities.
n
The components of these units are specifically designed for
R-407C refrigerant, and all units have been submitted to the
necessary laboratory tests to ensure perfect operation.
n
The unit incorporates two axial fans with horizontal air discharge. The advanced design allows exceptionally lownoise operation.
n
Compact unit dimensions facilitate installation of these
units in restricted spaces.
n
Prepainted steel panels.
n
Removable panels for improved service and easier access to
all components.
n
The condenser coils are constructed of high-quality copper
tube, expanded into pre-treated aluminium fins to offer high
corrosion resistance in industrial and marine environments.
n
The refrigerant-to-water heat exchangers are plate heat
exchangers, ensuring excellent heat transfer at reduced
dimensions and low weight. The plates are made of welded
stainless steel. This heat exchanger type requires only
minimum refrigerant quantities, compared with traditional
heat exchangers.
n
The scroll compressors run very quietly and vibration-free.
They are known for their durability and reliability. The
motor is fully cooled by suction gas and permits up to 12
starts per hour. The advanced concept of the scroll allows
reverse rotation due to incorrect wiring, without impairing
the operation of the compressor.
These compressors are especially designed for operation
with R-407C.
n
The hydronic module is factory-installed. This eliminates
the need to install the necessary components on site,
making the unit more compact and easy to install.

PRO-DIALOG Plus control
PRO-DIALOG Plus is an advanced numeric control system that combines complex intelligence with great operating simplicity. PRO-DIALOG Plus constantly monitors all
machine parameters and safety devices, and precisely
manages the operation of compressor and fans for optimum
energy efficiency. It also controls the operation of the water
pump.
A powerful control system
n
The PID control algorithm with permanent compensation
for the difference between entering and leaving water temperature anticipates load variations, and ensures intelligent
leaving water temperature control.
n
Reset of the leaving water temperature set point (according
to the outdoor air temperature or the return water
temperature).
n
PRO-DIALOG Plus control is auto-adaptive for improved
heat pump protection. Compressor cycling is automatically
adapted to the characteristics of the application according to
the inertia of the water loop and prevents dangerous compressor short cycling.
Clear and easy-to-use control system
n
The operator interface is clear and user-friendly: LEDs and
numeric displays ensure immediate verification of the unit
operating data.
n
A simple push of the button positioned on the synoptic heat
pump diagram gives you immediate display of the usual
parameters: temperatures, pressures, set point, compressor
run times etc.
n
10 menus offer direct access to all machine controls,
including fault history, for rapid fault diagnosis.
Extended communications capabilities
n
PRO-DIALOG Plus offers a standard wired remote control
with multiple functions for easy integration into any building management system: on/off control, cooling/heating
mode selection, power demand limit or dual set point and a
general alarm indication.
n
The optional CCN Clock Board offers enhanced control
possibilities: Time scheduling of the unit with up to eight
sequences, cascade operation of two units, remote control
by communication bus through its RS 485 serial port, time
scheduling for low-speed fan operation.
