Hot and Cool ACs – All-year-round comfort

Generally, when we discuss ACs, we refer to cooling the room and creating an excellent ambiance. However, the latest Blue Star ACs features a Heat Mode option that reverses the air conditioning process. This mode envisages the AC to work as a heater. The fan switches off, and the AC blows warm air into the room until it reaches the required temperature levels.

The Hot and Cold ACs thus prove to be all-year-round appliances instead of products with seasonal usage.

The premium Blue Star AC models do not use a heating filament similar to conventional heaters. Hence, these ACs are energy-efficient and eliminate the risks of low oxygen distribution because of zero-carbon residue. In addition, the inverter technology helps save up to 30% power consumption in the Heat Mode.

The Heat Mode features an anti-cool wind function where the indoor fan does not run until it achieves the desired warm air temperature. Thus, it provides better comfort to the user during the winter months.  

However, the Heat Mode is not available on all Blue Star ACs.

4D Wide Angle Airflow – Uniform cool air distribution

ACs cool the rooms by blowing cool air in multiple directions. Generally, you have ACs fitted with a 2-way swing blade for cool air dissemination. These louvers swing up and down. The latest Blue Star 5-star AC models feature a 4D swing feature that sees louvers moving up/down and right/left directions. Hence, it ensures blowing cool air to all parts of the room uniformly.

Besides, these louvers swing over a wide-angle to throw cool air into every corner of the room. Secondly, the user can change the airflow direction if the cool air draft blows right over their heads. So, this feature provides optimum comfort and quickly cools a more extensive area.

Copper Condenser with Hydrophilic Blue Fin Technology

The condenser and evaporator coils are critical components of your AC. Earlier, these coils used to be made from aluminum. Aluminum is a good choice, but it can get corroded easily. Hence, you have the latest ACs featuring copper condenser and evaporator coils. Compared to aluminum, copper is a better choice because it offers high-quality heat exchange.

Copper coils do not get corroded as easily as aluminum coils. Hence, these coils are durable. Besides, copper coils are easier to clean and maintain.

These copper coils are compactly placed inside the AC. So, dust particles accumulate in the gaps and affect the coil’s proper functioning.

Blue Star ACs feature an anti-corrosive hydrophilic bluefin that does not allow water condensation and dust particles to accumulate inside the gaps. Therefore, it reduces corrosion considerably. This technology is instrumental in industrial and coastal areas where you observe high pollution and ozone levels in the air.

Anti-Freeze Thermostat for all-round protection

ACs usually run at full blast during the summer months to provide much-needed comfort. Under such circumstances, there can be frost formation on the heat exchanger. The frost collection on the heat exchanger tubes can affect the cooling performance and, thereby, the appliance’s durability.

The latest Blue Star split ACs feature an anti-freeze thermostat on the indoor coil to prevent frost formation. In addition, the thermostat adjusts the compressor speed on attaining the requisite cold temperature.

Bluestar AC Outdoor unit

The outdoor units in split ACs are exposed to harsh climatic conditions. Hence, they require protection to last long. Blue Star ACs use galvanized steel in the manufacturing of their metal bodies.

Besides, the outer body is subject to a polyester powder paint coat for enhanced durability. This coating prevents rust formation and enhances the appliance’s lifespan.

The PCB is a critical component in any AC. Overheating of the electrical components can damage it. Blue Star ACs feature a metal enclosure for the PCB to protect it from damage.

Air Filtration Systems – A range of air purifying options

Most modern ACs feature air purifying systems to improve the air quality in the room. The latest Blue Star air conditioners work on cold plasma technology to generate a natural bioclimate inside the appliance.

Cold Plasma technology generates active positive and negative ions of hydrogen and oxygen to form bonds with harmful bacteria and other airborne contaminants to nullify their effect. The bond formation increases the pollutant’s particle size that enables the filters present in the appliance to trap them.

Besides Cold Plasma Technology, Blue Star ACs use eight filters to trap these contaminants from polluting the environment.

  • Dust Filter – It helps trap dust particles from the circulating air.
  • Anti-Acarien Filter – It removes dust mites and other allergens.
  • Bio Filter – This filtering technology comprises biological enzymes to purify the air. These enzymes eliminate bacteria by dissolving their cell walls. It also ensures that bacteria do not regrow, whereby you can experience the benefits of pure and healthy air.
  • Anti-Bacterial Filter – This filter sterilizes harmful bacteria such as Staphylococcus Aureus and E-Coli that cause infections and diarrhea.
  • Vitamin C Filter – This filter neutralizes the effect of radicals that interact with natural anti-oxidants. In addition, the cool air passing through the filters soothes and softens the skin by reducing stress.
  • Silver Ion Filter – It eliminates 99% of bacteria, viruses, and other microorganisms to purify the air circulating inside the room.
  • Active Carbon Filter – Similar to their functionality in water purifiers, the active carbon filters remove harmful hydrocarbons, unpleasant odors like ammonia, and chemical gases such as formaldehyde and benzene.
  • Catechin Filter – This filter proves handy in removing cigarette smoke and other pollutants.

Some latest Blue Star AC models feature Auto Clean functionality to clean the indoor coils and dry them. This technology works by running the blower for a few minutes after switching the air conditioner off. It prevents dust and mold accumulation on the interior coils. Besides, these ACs offer the convenience of manual cleaning because of their detachable front panel.
