3 KEY CUSTOMER BENEFITS
Nominal cooling capacity @ 12/7°C and 35°C air ambient: 50 to 330kW
Nominal heating capacity @ 40/45°C and 7°C air ambient: 50 to 340kW
3.1 The AQUA
4
P: unique concept for thermal comfort with less energy consumption.
The polyvalent heat pump AQUA
4
P units are designed to meet the requirements of simultaneous and independent cooling and
heating for air conditioning in the most efficient way. The AQUA
4
P units provide a hot water circuit and a cold water circuit to the entire
building and are more commonly called 4 pipe system.
3.2 The AQUA
4
M: hot water all the year at a lower cost.
The polyvalent heat pump AQUA
4
M units are designed to meet the requirements of cooling and / or heating in the most efficient way.
The units have the ability to provide hot water simultaneously or independently of cooling and heating needs. The AQUA
4
M units are
generally called 2 pipe units because two hydraulic pipes are connected to the terminal building, the other two hydraulic pipes are
generally dedicated to hot sanitary water.

(*) TER : Total Efficiency Ratio is the total energy efficiency of the units when there is a production of chilled water and hot water
simultaneously. Cold water and hot water are valuated to the total power consumption of the unit: TER = (cooling ca recovered
heating capacity) / total power consumption. Energy ratio TER of polyvalent heat pumps are significantly higher than the standard EER
and COP demonstrating considerable energy savings during inter-season periods (version P) or domestic hot water production (M
version).
