All units of the LCP series, regardless of size, can be made in a standard configuration “S” or a low-noise configuration “L”, in which the compressors and compressor compartment are covered with sound-deadening material and the unit is specially dimensioned so as to be compatible with a reduced fan speed.
 

All units of the LCP series, regardless of size, can be coupled with both 2- and 4-pipe systems, the letter “P” indicates heat pump with total recovery for 4-pipe systems and the letter “M” indicates multifunctional heat pump for 2-pipe systems.
 

LCP multifunctional units have 4 water connections for two different plumbing circuits for 2- or 4-pipe systems:
 

- Circuit 1, production of chilled water (or hot water if the unit is reversible like LCP M)

- Circuit 2, production of hot water through total heat recovery operating modes of the LCP M multifunctional unit.

Cooling In the “Chiller” mode the LCP M multifunctional unit chills water to cool a room on the user side, dissipating the condensation heat in air by means of a finned block condenser.
 

Heating In the “Heat Pump” mode the LCP M unit heats the water in the condenser to provide heating on the user side, absorbing the evaporative cooling capacity in air by means of a finned block heat exchanger. In other words, a certain amount of heat is drawn from the thermal source, air, which is delivered to the user after reaching a thermal level such as to satisfy needs.
 

Hot water production (for sanitary use-DHW) In the “Production of High-temperature Hot Water for sanitary use (DHW)” mode the LCP M multifunctional unit heats water in the second condenser, absorbing the evaporative cooling capacity in air by means of a finned block heat exchanger.
 

Cooling and hot water production through total recovery In the “Chiller + DHW” mode the LCP M multifunctional unit can produce chilled water with the simultaneous production of high-temperature hot water for sanitary use, thanks to total heat recovery.
 

Production of hot water (for example for sanitary use) simultaneously with heating in the “Simultaneous DHW Production and Heating” mode the LCP M multifunctional unit heats water in parallel, optimally exploiting the complete independence of its thermodynamic circuits. Capacity is equally divided between the two circuits.
 

LCP units enable the installation of a simple air conditioning system, either 2-pipe or 4-pipe. The designation “two-pipe” or “four-pipe” refers to the system for distributing the water used by all the air conditioning equipment of a building. A two-pipe system has a single supply line and a single line for the return of water to the unit. The indoor units served by a two-pipe system contain only an exchanger, which works alternatively as a heating or cooling coil, according to the operating mode.
 

The four-pipe system has a distribution system that simultaneously offers both hot water (with respective return lines) and chilled water (with respective return lines) (for example, cooling systems with dehumidification + post-heating). Two-pipe systems are less flexible than a four-pipe system, since the entire building is alternatively in the heating or cooling mode; however, they enable large savings to be achieved when it comes to installing the system.
 

If design requirements call for a 4-pipe system, LCP P units, compatible with this configuration, are available on request.
