Serie MVA, Sistema ad espansione diretta a flusso variabile di refrigerante VRF

• Units designed for installation in two-pipe and three-pipe systems.
• The perfect balance between cost, efficiency, and space.
• A wide range of indoor units available.
• Up to 80 units connectable.

Utilising R410A refrigerant and condensation control, this system comprises 1 to 4 outdoor units and, depending on the size and the number of outdoor modules, 2 to 80 indoor units which can be of the following types:

Cassette units (600x600, 840x840, 910x910) for suspended ceiling installations

Floor Ceiling units for wall or ceiling installations

Ducted units with high or low static pressure (horizontal installation)

Console units (floor installation)

Wall units (wall installation)

The outdoor unit employs DC inverter technology on both the fans and the scroll compressors. Refrigerant connections are made using mandatory “Y” joints provided as accessories. The operation of the system is managed by a microprocessor-based controller via a non-polarised serial connection using the CAN Bus protocol. A flush-mounted panel and an infrared remote control are standard with the indoor unit, and a centralised controller is available.
Thanks to their compact dimensions and streamlined design, these units are easy to transport on site—in fact, all models can be easily moved to the roof even via an elevator.

MVA_MHR

A modular multisplit VRF air conditioning system for three-pipe plants. This reversible air-to-air heat pump with DC inverter technology offers:
— Connectivity from 1 to 80 indoor units.
— A maximum total refrigerant line length of up to 1000 m.
— A modular system with base modules that can be combined up to a maximum of 4 for a total of 24 recommended combinations.
— DC inverter technology on both the compressor and the fan.
— An electronic expansion valve.
— A system that allows independent and simultaneous control of heating and cooling modes, with the possibility to manage hot and cold modes independently and concurrently. It is necessary to interface the external three-pipe units (MVA_MHR) with the two-pipe indoor units from the MVA series using the exchange module (MEB), available with one, two, four, or eight branches.

Special Golden Fin Battery
Unlike standard batteries, this special silicon-free epoxy-coated battery in a golden hue is capable of protecting the heat exchanger from rust and corrosion in areas with very high salt content in the air.

 
TRS1001DX

 

Heat recovery unit of 1000 m³/h with counterflow streams and a direct expansion battery. Built and manufactured to recover both sensible and latent heat and to deliver thermal power or cooling to the indoor environment. To complete the system, pairing with the flush-mounted panel WRC1 (accessory) is mandatory.

VRF Systems - 2-pipe Heat Pump

Customize your VRF system.
To ensure maximum seasonal efficiency and the highest comfort with the variable refrigerant function.
Continuous comfort.
The continuous heating or cooling of spaces makes the VRF system a viable alternative to hydronic systems.

 
Example of a two-pipe system installation

 

MVAS - MVAM
— 2-pipe system.
— Operates in cooling or heating mode. (The image shows an example of an installation in cooling mode)
— Maximum total refrigerant line length:
  • MVAS: 300 m
  • MVAM: 1000 m

VRF systems - 3-pipe heat pump
The MVAMHR VRF system with heat recovery provides simultaneous heating and cooling with a single unit.
MVAMHR recovers the heat generated during cooling to provide free heating for spaces that require it, maximising energy efficiency and reducing electricity costs.
Continuous comfort.
Simultaneous heating and cooling make the VRF system a valid alternative to hydronic systems.
