Multizonal VRF air conditioning systems

For offices and shopping malls featuring multiple functional areas

Multizonal VRF systems are designed to maintain the right microclimate in different areas of the same space. A VRF system consists of one outdoor unit and several indoor units. The indoor units are installed indoors, and the outdoor unit is placed in the basement, on the utility floor, or on the roof.

A VRF system offers a perfect mix of benefits: high performance, significant energy savings, and low noise level.

Each indoor unit of the system is connected to the outdoor unit via pipes. Depending on the type of air pipes used, multizonal VRF systems are classified as:

• Two-pipe (the system can either heat or cool all spaces)
• Three-pipe (the system can simultaneously cool some areas while heating others)

An extensive network of pipes ensures the delivery of freon to the selected consumer. The compressor can pump freon up to 100 m with a height difference of up to 50 m, which allows you to create large-scale VRF systems serving large office or commercial buildings

Main technical parameters:

• Operating temperature range in cooling mode: −10 to +55 °C
• Operating temperature range in heating mode: −30 to +30 °C
• Temperature adjustment accuracy up to 0.5 °C
• Indoor units with cooling capacity of 2.2 to 56 kW
• Indoor modules can be installed in the following configurations: cassette, wall, channel
• Outdoor units with cooling capacity of 8 to 90 kW
• It is possible to combine 2–4 outdoor units to build systems of up to 360 kW
