Wide Capacity Range Mini VRF Series operates stably under extreme conditions, ranging from minus 5°C to 48°C.
Long Piping Length
Wide Operation Range
Wide Range of Indoor UnitsMidea provides 9 types of VRF indoor units maximum meeting varied customer requirements. It is widely applied in market,
hospital, office building, hotel, airport, etc..
Wide Application Range
The outdoor units’ capacity range from 7.2kW to 17kW which is ideal for small offices, villas, apartment and shops, making it
perfect for commercial and residential application.
The Mini VRF provides a total piping length possibility of 100m, a maximum height difference between outdoor and indoor units
of 30m. The height difference between indoor units can be up to 8m. These generous allowances facilitate an extensive array of
system designs.
1 Total pipe length is equal to all the liquid pipe or all the gas pipe length.
2 When the total equivalent pipe length of liquid side plus gas side is more than 90m,
it needs to meet the specific conditions according to the installation part of the technical manual.

Easy Installation and Service
Space Saving Design
Easy Installation
Easy installation: No special area is required for outdoor units.
Easy transportaion: All outdoor units can be transported by elevator, which greatly simplifies installation and reduces time and
labor.
The Mini VRF system's indoor and outdoor units are almost as easy to install as residential airconditioning systems, making them
ideal for small offices and shops.
The Mini VRF units are slimmer and more compact, resulting in significant savings in installation space.
In some large residential and light commercial areas, such as villas, restaurants, usually it need more than one indoor unit,
which in turn requires multiple outdoor units.
Midea's Mini VRF system solves this problem, and retains buildings' original aesthetics.
Easy to transport
More Convenient Piping Connector - Branch Box
Easier and safer installation thanks to a branch box that simplifies piping work and the adoption of screw connection.
Both left and right pipe flare connectin from outdoor unit to branch box is reserved, which greatly simplifies field installation.

Notes:1. Indoor air temperature 27℃ (80.6℉) DB, 19℃ (66.2℉) WB; outdoor air temperature 35℃ (95℉) DB; equivalent refrigerant piping length 7.5m (24.6ft.) with zero level difference. 2. Sound pressure level is measured at a position 1m (3.28ft.) in front of the unit and 1.3m (4.26ft.) above the floor in a semi-anechoic chamber.3. For a system with more than one IDU, to ensure even distribution of refrigant, the capacity of each indoor unit should not exceed 8kW.
