Hydraulic Part - flowair AURA HCS Series Installation And Operating Instruction

The location of the device also affects the sound pressure level around the device. If the device is installed near the
acoustically hard walls of the building, the values of the sound pressure at a distance of 10 m will be higher than the nominal
values stated in the Technical Parameters Card supplied with the device documentation. (There is a change of the Directional
factor Q = 2 – half space to Q = 4 – quarter space and thus an increase in the sound pressure level Lp independently of
maintaining the sound power level Lw of the cooling device).

3.2. Hydraulic part

The hydraulic part of the cooling equipment (except for the CU version - condensing unit) always consists of the evaporator
water circuit together with temperature sensors and flow sensor, other equipment is optional when ordering the equipment.
The technological diagram for the evaporator and recuperation circuit together with the explanations is described in the
following figures with a table.
