12.2 - Description
12.2.1 - Hydraulic module without variable speed
(options 116R, 116S, 116T, 116U)
The hydraulic module is composed of the system's main
hydraulic components: factory-fitted water pump, screen filter
and relief valve.
The fixed speed operating pressure pump provides the nominal
flow rate for the system water loop.
Several types of water pump are available to suit all applications:
•
Single or dual low pressure pumps
• Single or dual high pressure pumps.
The nominal flow rate of the system should be adjusted using
a manual control valve provided by the customer.
The relief valve placed on the water inlet pipes at the pump
inlet limits the pressure to 400 kPa (4 bar).
A screen filter that can be easily removed is placed at the pump
inlet and protects the pump and the plate heat exchanger against
solid particles that are greater than 1.2 mm.
Additional options can be ordered if necessary:
•
Protection of the hydraulic module in outdoor
temperatures of down to -20°C.
• Expansion vessel.
The use of the hydraulic module on open systems is
prohibited.
12.2.2 - Hydraulic module with variable speed
(Options 116V, 116W)
The composition of the hydraulic module with variable speed
is similar to that of the hydraulic module without variable
speed.
In this case, the pump is controlled by a frequency inverter
that allows the pump's nominal flow to be adjusted based on
the chosen control mode (constant pressure or temperature
differential or fixed speed) and the installation's operating
conditions.
The use of the hydraulic module on open systems is
prohibited.
12.2.3 - Partial heat recovery (Option 49)
This option enables free hot water to be produced through
heat recovery by desuperheating the compressor outlet gas.
The option is available across the entire range.
A water-cooled heat exchanger is installed as standard with
air-cooled exchangers on the compressor discharge line on
each circuit.
The control is configured for the partial heat recovery option
in the factory (see the section on Control configuration with
the desuperheater option).
The installer must protect the water type heat exchanger
against the risk of frost.
