Centrifugal Fan

Adopt centrifugal fan with lower power consumption and longer air supply distance; easy control, friendly operation. All units are equipped with 3-speed fan mode, adjusting the air flow rate in accordance with the ceiling height. Innovative centrifugal fan provides larger air volume but lower noise, making the air supply more quietly and smoothly.

Different Modes for Your Choice

Exhausting mode (Hi/Mid/Low fan speed can be chosen)

Air supply mode (Hi/Mid/Low fan speed can be chosen)

By pass mode (Hi/Mid/Low fan speed can be chosen)
In this mode, there is no heat exchanging happened, which is more energy saving.
For example: If outdoor temperature is lower than indoor, we don’t need heat exchanging, but we need fresh air. We can choose by pass mode.
Remark: this mode is only available for HRV-200~1000.

Heat exchanging mode (Hi/Mid/Low fan speed can be chosen)
In this mode, supply air flow = exhaust air flow.

Auto mode
In this mode, the unit will run at heat exchange mode or by pass mode judged by outdoor temperature and indoor temperature with low speed.

Built-in Water Drainage Pump

Standard built-in drain pump with 1200 mm pump head.

Ultra Slim Design

Only 250 mm in height to save installation space.

Fresh Air Intake

Fresh air makes indoor air healthy and comfortable.

Quiet Operation

Innovative 3D spiral wind leaf increases air volume and makes the air supply more quietly and smoothly.

Digital Tube Display

Digital tube displays all contents: indoor temperature, setting temperature, operation mode, etc. Clearly to check the running status, more convenient for trouble shooting.

2 Ways Draining Connection

There are two outlets in the left and right side of the unit. Both are compatible for a drainage hose connection and easy installation.

Built-in Water Pump

The built-in pump can lift condensing water up to 700 mm high from the drainage pan.

Ultra Slim Design

Only 290 mm in height, save installation space.

Optional ESP

50 Pa and 80 Pa are both optional.

Fresh Air Intake 

Fresh air makes indoor air healthy
and comfortable.

Flexible Air Intake Options

Air intake is standard from rear and optional from the bottom. The size of the plate from the bottom is as the same as the flange from the back, which makes it convenient to change installation style according to different decoration requirements.

Innovative Air Supply Technology for Excellent Room Temperature Control

For all fresh air processor models, the return air from bellow and air filter are standard configuration. The high ESP makes the air supply distance up to 50 m.

Applicable to A Variety of Room Types

Specific ESP design can be applied to various room types easily. Rooms like the L type or U type. The air outlet can be set separately from the indoor unit, so the air flow can be equally distributed even if the room was in an irregular structure.

4D Air Swing

Vertical and horizontal swing makes air below to every corner of the room.

Innovative Centrifugal Fan

All units are equipped with 3-speed fan mode, adjusting the air flow rate in accordance with the ceiling height. Innovative centrifugal fan provides larger air volume but lower noise, making the air supply more quietly and smoothly.

Flexible Installation

Can be vertically installed against the wall or horizontally installed under the ceiling.

2 Ways Draining Connection 

Both left and right sides of the unit are possible for drainage pipe connection and easy installation.

Wired Control

Wireless remote controller is a standard, while the wired controller is optional. Wired controller can be fixed on the wall to avoid mislaying. It’s mainly used for commercial zone and makes air conditioner control more convenient.

Wide Operation Range

The unit could operate perfectly between 54°C in hot summer and -15°C in cold winter making you feel like spring all year around with advanced system design and strict matching test.

  Wide Voltage Design 

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

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.

Fast Cooling/Heating Technology

The DC Inverter Compressor system reaches full load rapidly providing less temperature fluctuation and an improved living environment, bringing great user experience.

Accurate Temperature Control

According to the change trend of the indoor ambient temperature, the unit can use PI algorithm to calculate the capacity demand percentage of the indoor unit, control operating frequency of compressor in real time and reach accurate control of room temperature.

Auto Restart Function

The system can automatically memorize the operation setting when power is cut off accidently. It can return to the previous setting when the power resumes. Recovering the former operation state when the power is restored.

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.
