Unitate exterioara VRF Vivax, Seria VMV 5H, VMV-H735ARETA3, 73.5 kW, Continuous Heating

High Efficiency

EVI compressor and two-stage subcooling

VMV 5H units are equipped with a refrigerant sub-cooler and an enhanced vapor injection compressor. It is increasing the system performance and capacity in the wide range of ambient conditions, increasing the compressor efficiency, and reducing the operation costs.

DC inverter stepless fan motor

The outdoor fan motor has stepless inverter regulation technology and is able to operate in the 0-91 Hz frequency range which increases efficiency.

Superconducting refrigerant cooling PCB technology

Adopt innovative super heat conduction cooling PCB technology, heat transfer media conduct heat 100 times better than copper. Does not occupy the refrigerant amount of the system, no additional refrigerant loss. At the same time, this cooling mode will not affect the rotation of the electric control box, easy maintain.

High comfort

Continuous heating technology

The VMV 5H units have intelligent defrost technology. During the light and medium defrost demand, defrosting is achieved by a hot-gas bypass ensuring the continuous heating and maximum comfort during defrosting of outdoor heat exchanger.

Precise temperature control

The VMV 5 units are equipped with double pressure sensors and double electronic expansion valves which enable the automatic refrigerant volume adjustment. With this technology indoor temperature could be controlled by 0,5 °C steps improving the comfort.

Wide operation temperature range

Special design of the VMV 5H series enables the heating operation at outdoor temperatures down to -27 °C, and coling operation at outdoor temperatures up to 52 °C. Cooling operation outdoor temperature range: -5 °C - 52 °C. Heating operation outdoor temperature range: -27 °C - 21 °C.

Easy installation

Auto addressing indoor units

The outdoor unit can automatically address the indoor units through the module on the PCB. It is more convenient and time saving as there is no need to manually set the addresses on each indoor units separately.

Easy access for maintenance and repair

Rotating design of the electronic control box allows easy access to all internal system components, and saves time during maintenance..

Flexible long piping design

1000 m maximum total piping length

220 m maximum actual piping length

110 m / 90 m maximum height difference between ODU and IDU (ODU higher / IDU higher)

30 m maximum height difference between IDU and IDU

* for the total piping length between 300 m and 1000 m, and height difference grater than 50m please contact your supplier

Four-way refrigerant piping connection

Refrigerant pipes can be connected from four different directions which makes the piping installation simpler while saving time and material.
