Optimized condenser coil design

The condenser coil is split in half and refrigerant flow through each part is independently controlled by the separate electronic expansion valve. In this way refrigerant flow and heat exchange area are always optimized to match the indoor units load demand, thus increasing the heat exchange efficiency and improving the system performance.

High efficiency

Increased efficiency with full DC inverter compressor

Matches up inverter with stepless compressor, the durability and stability of the compressor are guaranteed, fault can be reduced.

Each compressor is adopted oil temperature sensor and the discharge temperature sensor, detecting the discharge temperature and oil temperature of compressor, cooperated with the compressor frequency and the EEV control, to ensure exhaust heat and oil temperature superheat kept within the optimal range. Ensure that the oil dilution is maintained at a safe level at all times.

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.

Temperature approaching technology

The main problem of an ordinary inverter VRF system lies in that its compressor starts and stops frequently, stopping when the room temperature reaches the setting temperature and restarting when the same becomes higher than the setting temperature. Though the inverter technology has improved such a problem greatly, the energy consumption caused by system restart is still a problem that cannot be ignored. VMV 5 series units adopts the temperature approaching technology, which enables the VRF system to maintain a low-frequency operating state all the time when the room temperature is close to the setting temperature but doesn‘t reach the setting temperature, thus avoiding the energy waste caused by frequent on / off.

New four-way heat exchanger

High comfort

Wide operation temperature range

The operation in heating and cooling are improved and temperature limits are -23 °C in heating and 50 °C in cooling.

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.

Intelligent backup operation technology

In the case of a compressor malfunction another compressor (single outdoor unit with two compressors) or outdoor unit (multi module outdoor system) will enter in the backup operation. Units will continue to operate for 8 hours allowing the time for repair while providing the indoor comfort.

Easy Installation

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.

110 Pa external static pressure

External static pressure of outdoor unit air outlet can be set up to 110 Pa which allows multiple installation options.

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.

Automatic oil balancing

In the multi module outdoor system the oil level in every module is balanced automatically. In such system there is no need for oil balancing pipes which simplifies the system design and improves reliability.

Automatic snow and dust removal

The outdoor unit has the function of preventing snow accumulation on top of the unit. The dust can be blown away from the outdoor heat exchanger by reversing the operation of the fan.

Night time low noise operation mode

It is possible to set the low noise operation mode which reduces the sound level by 10 dB(A). This function is useful when units are installed in residential areas, as well as in other noise-sensitive places.
