GENERAL FEATURES
Unit description
This series of air-water chillers and heat pumps satisfies the co-
oling and heating requirements of residential plants of small and
medium size.
All the units are suitable for outdoor installation and can be ap-
plied to fan coil plants, radiant floor plants and high efficiency
radiators plants.
The refrigerant circuit, contained in a compartment protected
from the air flow to simplify the maintenance operations, is
equipped with scroll compressor mounted on damper supports,
brazed plate heat exchanger, thermostatic expansion valve, re-
verse cycle valve, axial fans with safety protection grilles, finned
coil made of copper pipes and aluminium louvered fins. The cir-
cuit is protected by high and low pressure switches and differen-
tial pressure switch on the plate heat exchanger.
The plate heat exchanger and all the hydraulic pipes are ther-
mally insulated in order to avoid condensate generation and to
reduce thermal losses.
All the units can be equipped with variable speed fans control
that allows the units to operate with low outdoor temperatures in
cooling and high outdoor temperature in heating and permits to
reduce noise emissions in such operating conditions.
The low noise acoustic setting up (AS) is obtained, starting from
the base setting up (AB), reducing the rotational speed of the
fans and mounting sound jackets on the compressors.
All the units are supplied with an outdoor temperature sensor, al-
ready installed on the unit, in order to realize the climatic control.
All the units are provided with a phase presence and correct
sequence controller device.
All the units are accurately built and individually tested in the
factory. Only electric and hydraulic connections are required for
installation.
