OUTDOOR UNITS

Wide Operation Range

No matter in hot summer or cold winter, VRF-X can supply comfortable environment for users.

Wide Voltage Design

In countries with unstable voltage, VRF-X system could still run stably.

High EER

VRF-X tropical series have an excellent energy efficiency in cooling mode by utilizing all DC inverter compressors. At T3 condition the maximum cooling EER can reaches up to 3.59.

180° Sine Wave Control

DC inverter compressor uses 180° sine wave vector control technique that makes the motor operates smoothly and increases the efficiency. Significantly compared with the traditional sawtooth wave, it can also lower the noise level.

Precise Temperature Control Humanization Design

WARTH composite temperature control technology, can detect the indoor/outdoor operation condition and adjust the outdoor output power and optimize the indoor air distribution. This can achieve the high precision adjustment of 0.5°C.

2-stage Sub-cooling Technology

The first stage sub-cooling process took place due to the optimized refrigerant circuit and “Inverse fin type” window fin design. The second stage sub-cooling process took place by a high efficiency plate heat exchanger with a sub-cooling EXV.

Refrigerant PCB Cooling System

The PCB is well cooled by the refrigerant, ensuring the system operate steadily even in tropical area. Frequency limits of the inverter compressor can be relaxed, so that the output capacity of ODU can be higher than conventional products.

Oil Return Control Technology

Dynamic Oil Return Control Technology
Monitoring the compressor running state and running time, computing the system reasonable oil return time.

6-Step Oil Separating Technology
Completely solve the problems of oil, the system more stable and reliable.

Compressor Throwing Oil Technology
When the compressor oil level higher than the warning line, system through tubing eliminate redundant frozen oil, keep the oil balance between compressor.

No Oil Balance Pipe Between ODUs

High efficient oil/gas separating technology can achieve oil balance of the system between the compressors without the oil balance pipe.

Long Piping Length

Thanks to the DC inverter control technology and the sub-cooling circuit technology ,it is possible to design systems with longer piping and elevation for easy installation.

Max. Total piping length — 1000 m
Max. Actual piping length — 240 m
Max. piping length from 1st indoor branch to the farthest indoor unit — 40 m
Max. Level difference between indoor units — 30 m
Max. Level difference between ODU and IDU units — 110 m

360° Pipe-connecting Mode

VRF-X series can be connected to the refrigerant pipes from the front, left side and right side for the free pipe direction.

Auto Refrigerant Recycling & Auto Refrigerant Charging

Refrigerant can be recycled to the outdoor units or indoor units whenever maintenance is needed. The outdoor unit can adjust the refrigerant amount according to the operation parameters such as pressure and temperature, and remind the installation personnel to stop charging.

Non-Polar Communication

No polar in communication wire ,easy installation and commissioning.

Back-Up Operation Technology

Module Emergency

As one module breaks down, module emergency can be set, then the rest modules in same combination can run normally.

Compressor Emergency

As one compressor breaks down, compressor emergency can be set, then another compressor in this unit can run normally.

Auto Dust Removal

Auto Dust Removal function is optional for VRF-X Tropical series, the outdoor fan can rotate in an opposite direction to remove the dust on the heat exchanger, and the system can operate steadily in severe environment without manual cleaning.
