Total heat recovery multi-purpose heat pumps - LCP
LCP 52 - 314 kW
MAIN COMPONENTS
Fans
Heat exchanger
Electronic microprocessor controller
Compressors
Refrigerating circuits
4/6/8-pole axial-type fans with
airfoil-shaped blades made of
hybrid plastic/aluminium material,
statically and dynamically balanced
in two planes, fitted with a pro-
tective grille and mounted with
rubber vibration dampers placed
in between.
Option to select the condensation
pressure-switch control with va-
riation of the air-flow rate through
electronic switching operated fans,
to operate in cooling mode at low
temperatures (up to -15°C)
Hydrophilic finned block heat exchangers are installed;
these break down the drops of water into particles and
reduce the obstruction of the space between one fin and
another caused by ice build-up. Thanks to a lower surface
tension, the water tends to slide and precipitate by gravity,
preventing the formation of frost at low temperatures.
LCP units are supplied with an Advanced microprocessor controller. In addition to the functions described
below, this microprocessor offers the option of custom software features to ensure optimal satisfaction of all
system requirements, including control of the unit with step-control or cascade logic.
As regards remote communication options, the controls are configured for a connection to advanced BMS
systems.
The scroll compressor today represents the best solution in terms
of reliability and efficiency in the range of capacities up to 200
kW per circuit and the best solution in terms of sound power
emitted. The use of scroll compressors makes it possible to use
low-viscosity oils which, compared to solutions with oil at a high
viscosity level, reduce thermal resistance at the evaporator with
increases in the evaporation temperature of over 1.5°C (more than
a 5.5% gain in terms of EER) compared to alternative solutions.
Thanks to the presence of two inde-
pendent thermodynamic circuits,
the LCP M is capable of producing
hot water for heating while simulta-
neously carrying out a defrost cycle
or guaranteeing the replenishment
of domestic hot water.
AVAILABLE VERSIONS
Operating modes available for an LCP M unit which interfaces with a 2-pipe system.
C1 Hydraulic circuit manages winter heating and summer air-conditioning while the
C2 one is used for the production of DHW, ensuring this function 365 days per year.
In case of simultaneous production of cold (C1) and high-temperature water for
domestic use (C2), the machine is able to recover all the condensation heat on the
refrigerant for the production of DHW.
Operating modes available for an LCP P unit which interfaces with a 4-pipe air
conditioning system.
In this kind of systems, it is possible to request air-conditioning and heating at the
same time. For this reason, C1 and C2 hydraulic circuits respectively produce cold
and hot water.
In case of simultaneous operation of C1 and C2 hydraulic circuits, the condensation
heat of the cooling system is totally recovered for the production of hot water.
