  • Page 7: Description Of The Component

    GENERAL FEATURES Description of the component 1. Fans. Axial type, they are contained in a sheet nozzle and are equipped with a safety grille, scythe-shaped blades increase the efficiency and reduce the noise level. The fans are directly coupled to the single-phase motor by means of an external rotor. Thermal protection against operating faults is installed inside the winding.
  • Page 8 GENERAL FEATURES 3. Compressors. They are the SCROLL type with orbiting coil equipped with built-in thermal protection and oil heater (accessory for IR, as standard for IP). The AS unit includes: a soundproofing jacket for the compressors, to reduce noise level. All units are equipped with two compressors connected in parallel (1 single cooling circuit) which can operate at the same time (100% cooling power) or individually (50% of the cooling power), thus adapting to the different thermal loads of the system supplied.
  • Page 9 GENERAL FEATURES Hydraulic and cooling circuit components 7.One-way valves (IP unit only), allowing the refrigerant gas to pass into the appropriate exchangers, depending on the operating cycle. 8. 4-way cycle reversal valve (IP unit only), reverses the flow direction of the refrigerant gas as the summer/winter operating mode is changed.
  • Page 10 GENERAL FEATURES Desuperheater unit VD (available for both IR units and IP units) Hydraulic and chilling circuit components: 1. Desuperheater. Specially designed for the specific version. Plate type, made of stainless steel (AISI 316). It is installed within a shell of thermal barrier insulating material to prevent heat exchanges towards the outside. Standard supply also includes an electric antifreeze heater to prevent the parts from freezing during the winter, when the system remains at a standstill (if not drained).
  • Page 11 GENERAL FEATURES Total Heat Recovery unit VR (only available for IR units) Hydraulic and cooling circuit components: 1. Heat recovery exchanger. Specially designed for the specific version. Plate type, made of stainless steel (AISI 316). It is instal- led within a shell of thermal barrier insulating material to prevent heat dispersion towards the outside. Standard supply also includes an electric antifreeze heater to prevent the parts from freezing during the winter, if is it not drained.

  • Page 46: Noise Levels

    NOISE LEVELS Open field The noise levels refer to units operating in the nominal conditions (A35W7), due to a change of external air temperature noise levels may change to ensure proper functioning of the unit within operating range. The acoustic pressure levels are calculated 1/ 5 / 10 meters away from the outer surface of the unit operating in the free field and resting on a reflecting surface (directional factor of 2).

  • Page 47: Operating Range

    OPERATING RANGE Operating range The table below lists the operating ranges within which correct operation of the units is guaranteed, depending on the Version and Operating Mode available for each type of unit. Remember that in Heat Pump units, heat recovery only takes place during operation in the cooling mode. NOTE: the admissible limits for water flow rate on heat exchangers are indicated under the related pressure drop graph (see section "water pressure drop").
