ENHANCED COMFORTIntelligent soft start technology

Nighttime silent operation mode

DC inverter compressor soft start function reduces strike to the electric network. This kind of high-performance and low sound scroll compressor operates at a faster rate when starting, reducing start-up time. It helps the unit to bring the room temperature up to the set level quickly.

Midea's Night Silent Mode feature which is easily set on the PCB board allows the unit to be set to varies time options during Non Peak and Peak operation time optimizing the units noise output. Extra silent operation mode can reduce sound level further, minimum 46.8dB (A).Nighttime silent operation will be activated X hours after the peak temperature during daytime, and it will go back to normal operation after Y hours.

-Model 1X: 6 hours, Y: 10 hours -Model 2X: 8 hours, Y: 10 hours-Model 3X: 6 hours, Y: 12 hours -Model 4X: 8 hours, Y: 8 hours

Notes: This function can be activatedby setting at site. Temperature(load) curve shown in the graph is just an example.

*1&*2 can be set on PCB board by DIP switch S2.

Main Features Auto addressing

More convenience in installation

Benefits of using R410A refrigerant

Addressing indoor units are able to be done just by pressing the button of the controller.No need to set the address by the DIP switch one by one.Wired controller and wireless controller can enquiry and modify every indoor units address.

Smooth control

Wide operation temperature range

The operation range of the Mini VRF system works to reduce limitations on installation locations. The opera-tion temperature range for heating goes all the way down to 5F, while cooling can be performed with outdoor temperatures as high as 118.4F. Both these achievements are due to the employment of a high pressure dome-type compressor.

By using all inverter-driven compressors, Midea is able to significantly reduce the electrical and mechanical stresses that are placed on fixed-speed compressors during start-up. Current absorption on an inverter-driven compressor is smoothed out at start-up thus reducing the wear on the electrical and mechanical com-ponents and increasing reliability.

To suit the variety of rooms found in small offices and shops,the Mini VRF system offers wide range of indoor and outdoor units .mini VRF indoor and outdoor units are almost as easy to install as residential air conditioning systems , making them ideal for small offices and shops .

Offering four direction space for installation to connect pipes and wirings for meet a variety installation request.

Zero ozone-depleting potential

Significant increase in energy efficiency.

Reduced pressure loss for improved performance.

Making continuous efforts to stay eco-friendly, midea's air conditioners use R-410A, an environmentally friendly refrigerant to help rid the air of pollutants and restrain the use of materials with high global warming potential (GWP). Incorporating the Energy efficient, non-ozone-depleting R410A refrigerant in air conditioning systems delivers multiple benefits:

Up to 118.4F in cooling mode and down to 5F in heating mode.

More convenient piping connector - branch box

New piping connection design

Easier and safer installation thanks to a branch box that simplifies piping work and the adoption of screw connection.

Both left and right pipe screw connection from outdoor unit to branch box is reserved, simplified the field installation.

Two sets of pipe size converter are packed with branch box to transfer the pipe size from 1/4in. to 3/8in. and from1/2in. to 5/8in.

The branch pipe is linear expansion design which regu-lates the flow of refrigerant and reduces the noise. By locating the branch box in the ceiling or outside ,noise generated by the branch box can be kept clear of living spaces, thus maintaining the noise level to a minimum.

All the piping leading to and from the branch box is connected using screw joints,which are easy to use and enable piping installation to be completed quickly.

Brazing-free quick installation

Indoor installation

Universal indoor units

The branch box can be installed in the ceiling rather than outside. Furthermore, servicing can be complete easily through access to inner components such as the circuit board by simply removing the side and bottom covers.

The same indoor units as R410a DC inverter mini VRF system.
