Intelligent energy optimization with up to 37% energy savings compared to models without artificial intelligence.
Offline Voice
Convenient voice control even without an active internet connection.
56°C Self-Cleaning
Automatic high-temperature cleaning of the indoor unit for improved hygiene.
6-in-1 Filter
Multi-stage filter system for cleaner and more pleasant indoor air.
T-AI Energy Saving
Intelligent energy savings without compromising comfort
The TCL VoxIN uses “T-AI” energy-saving technology to intelligently adjust operation based on room temperature, usage, and power requirements. This allows the air conditioner to operate particularly efficiently and reduce energy consumption in everyday use—according to TCL, with energy savings of up to 37%+ compared to models without AI energy-saving technology.
The result: a comfortable temperature, consistent performance, and optimized power consumption.
Voice Control Without an Internet Connection
Control your air conditioning easily with your voice—even offline
Change the temperature, select an operating mode, or turn the unit on and off: The VoxIN series supports convenient voice control via an offline voice module. This allows you to operate key functions by voice even when no internet connection is available.
This makes operation particularly convenient in everyday life—no smartphone, no app, and no need to search for the remote control.
TCL HOME App & Wi-Fi Control
Smart Air Conditioning with Energy Monitoring
With the TCL HOME app, you can conveniently control your indoor climate—whether you’re at home or on the go.
Remote control via the app: Easily adjust the temperature, operating mode, timer, and other settings using your smartphone.
Energy Consumption Monitoring: Monitor energy usage directly in the app and optimize your daily use.
Smart Learning: The air conditioner can learn your usage habits and comfortably adapt its operation to your daily routine.
Arrive/Leave Home Mode: Convenient automation when you arrive home or leave the house.
Easy OTA Update: Supports cloud-based updates to keep electronic controls and functions up to date.
Strong performance in extreme outdoor temperatures
Reliable cooling and heating even under demanding conditions
The TCL VoxIN series is designed for a particularly wide range of outdoor temperatures. In cooling mode, it operates at outdoor temperatures ranging from -25°C to 53°C. In heating mode, it can even be used from -25°C to 26°C.
This makes the system suitable not only for hot summer days but also for cold transitional seasons and challenging winter conditions.
30-Second Turbo Cooling
Fast cooling when it counts
The TCL VoxIN achieves a noticeable cooling effect very quickly. Ideal on hot days when you need to bring the room up to a comfortable temperature quickly.
I FEEL function via remote control
Temperature measurement right where you are
With the I FEEL function, the temperature sensor in the remote control measures the room temperature right where you are. This allows the air conditioner to respond more effectively to the area where you’re actually located—rather than just measuring at the indoor unit.
This ensures more precise temperature control and greater comfort in everyday life.
Gentle air distribution with the Gentle Breeze function
Gentle air distribution instead of an unpleasant cold draft
Gentle Breeze uses micro-perforated louvers to create a particularly gentle airflow. The cooled air is distributed more comfortably, and harsh, direct drafts are reduced.
Dual-louver design for wide air distribution
Powerful air distribution for greater comfort in the room
The large cross-flow fan and the Wide Range Dual-Louver design support even air distribution. This ensures that cooled or heated air is efficiently distributed throughout the room, noticeably improving comfort.
Heating during the transitional season
More Than Just an Air Conditioner
In addition to its cooling function, the VoxIN series also offers a powerful heating function. Especially in spring, fall, or on cool days, the unit provides a comfortable solution for heating rooms quickly and efficiently.
Quiet Operation
Pleasantly quiet—ideal for living rooms, bedrooms, and offices
With low sound pressure levels indoors, the TCL VoxIN operates particularly quietly. Depending on the model and fan speed, the indoor unit achieves levels as low as 19 dB(A), making it suitable even for quiet areas.
56 °C self-cleaning & automatic cleaning of the outdoor unit
Automatic cleaning for improved hygiene and consistently strong performance
The 56°C self-cleaning function automatically cleans the indoor unit using high temperatures. This reduces moisture, dust, and deposits, contributing to more hygienic operation and pleasant indoor air quality.
In addition, the VoxIN series supports self-cleaning of the outdoor unit. Reverse-Clean technology helps loosen dirt on the outdoor unit and maintain performance over the long term.
6-in-1 Filter System
Multi-stage air filtration for a more comfortable indoor climate
The 6-in-1 filter system combines multiple filter stages to help ensure clean indoor air:
- Silver-ion filter
- Catechin filter
- Photocatalytic filter
- Anti-Dust Antistatic Filter
- Activated carbon filter
- Vitamin C filter
A+++ High Energy Efficiency
Powerful performance with efficient energy use
The TCL VoxIN series achieves very high efficiency ratings in cooling mode and offers an energy efficiency class of up to A+++. The combination of DC inverter technology, “T-AI” Energy Saving, and app-based consumption monitoring helps to specifically reduce energy consumption in everyday use.
Auto-Restart in Case of Power Outage & External Control Option
Practical for everyday use, ideal for commercial and institutional settings
After a power outage, the air conditioner automatically restarts with the previous settings. This is particularly convenient when the unit is used regularly.
Via Dry Contact Control, the VoxIN series can also be integrated into specific control scenarios, such as with door/window contacts, fire alarm systems, or building management systems. This makes it suitable for offices, hotels, vacation rentals, and commercial applications.

1*) Annual energy consumption (kWh/year). Based on standard test results. Actual consumption depends on usage, room size, insulation, and the unit’s location. 2*) Refrigerant leaks contribute to climate change. The refrigerant with a lower global warming potential (GWP) contributes less to global warming in the event of a leak than the refrigerant with a higher global warming potential. Do not perform any work on the refrigeration circuit or disassemble the unit—always consult qualified personnel.
FUTURE-PROOF, ECOLOGICAL
R32
Why switch to R32?
According to EU Regulation CE 517 2014, R410A will be phased out and replaced with non-fluorinated gases (F-gases) such as R32 for environmental reasons. Smaller charge quantities are required, and the gas can be more easily recycled and reused.
Environmentally Friendly
Positive effects include no impact on the ozone layer and a reduction in global warming potential. A transition period for R410A will be in effect starting in 2017—as of 2025, imports for systems with a charge capacity of less than 3 kg will be prohibited. As a simple refrigerant—not a compound—R32 can be easily recycled and reused. This makes it environmentally friendly.
Advantages over R410A
- ∼70% lower global warming potential
- 0% ozone impact
- Future-proof
- Lower global warming potential
Vision for the Future
Today, protecting the environment is one of society’s most important challenges. Both end users and manufacturers are doing their best to protect the environment as much as they can. As one of the pioneers in air conditioning manufacturing, TCL is committed to “R32.”
Effort for HVAC Technicians
Since “R32” requires no extra effort and is as easy to install as “R410A,” there will be no additional costs. On the contrary, “R32” is more cost-effective because it requires less refrigerant for the same cooling capacity.
