1. Key Refrigerator Technologies
1. Convertible Refrigerator for Optimized Refrigeration.
Managing a multi-door refrigerator in an optimized way can be challenging. Because there are times
when you don’t need the freezer or just have a small quantity of food to store. In such cases,
big brands like Samsung and LG offers a convertibility option which allows the freezer to be
converted to the fridge or to even shut off the freezer/fridge compartment altogether. Samsung
models like RT65K7 and RT61K7 are the best in offering this functionality as they offer five different
convertible options mentioned as follows:
Normal mode: This is the usual mode with the top compartment of the refrigerator used as freezer
while the bigger bottom part for normal refrigeration. With this option enabled, users can not just
have a fridge space that keeps a fresh supply of food for long but also a freezer which gives ice
faster.
Extra Fridge mode: Extra Fridge mode gives the liberty to convert freezer compartment into the
normal. This feature is useful for someone who often ends up bringing home more bags of
vegetables than that can be stuffed inside the refrigerator.
Seasonal mode: Seasonal mode allows turning off the freezer without impacting the smooth
functioning of the refrigerator compartment. This function is useful when there isn’t any food items
left for freezing.
Vacation mode: Refrigerator works 24×7, 365 days a year. This means they are incessantly
consuming electricity. There would be times when the user would move out of your home/city for
vacation, wedding, or other purposes. That too for a longer period of days. Obviously then, neither
they would be carrying along the refrigerator nor would be anyone using it. But the ordinary
refrigerator would keep on vociferously piling up on electricity units. To rescue users out of this
predicament, Samsung offers Vacation mode wherein user can simply turn off the bottom
refrigerator compartment while only the freezer compartment continues to work usually.
Home Alone mode: Home Alone mode is the most energy saving mode wherein users can simply
shut down the refrigerator compartment and shift all the small stock of perishables to the top
compartment which is now converted into a mini refrigerator.
Taking cues from its Samsung, LG also offers something called Dual Fridge. Using Dual Fridge
technology users can convert the freezer into the normal refrigerator. LG’s converter technology is
arguably the fastest with conversion time being less than 70 minutes.
2. Ice Beam Door, Dual Fan and 360o Airflow for All-around Cooling
Cooling technology has seen a significant improvement over last few years. The modern refrigerator
comes with strategically placed cooling vents which ensure the cool air inside the refrigerator is
circulated in a uniform manner, so there is no discrepancy in the cooling.
Modern single and double door refrigerators from Haier come with a technology called 360 Degree
Air Flow that maintains the even temperature throughout the refrigerator. It circulates air
uniformly in multiple directions from its multi air flow vents so that every corner of the refrigerator
is evenly cooled. This air flow system helps to cleanly keep the interior uniformly cool, free from any
odd frozen or warm spots. Thus, the stored food item remains fresh for longer with this astutely
designed air flow system.
Like 360-degree Airflow offered by Haier, Whirlpool offers 3D Airflow technology which imparts
uniform cooling through a strategically placed pair of flexible vents. It also allows the user to set the
direction of cool air.
A New double door refrigerator from LG comes with Ice Beam Door Cooling technology that
maintains the even temperature throughout the refrigerator. It circulates air uniformly in multiple
directions from its multi air flow vents along with the back so that every corner of the refrigerator is
2. evenly cooled. This decreases the temperature gap between the inner part and the door side of the
compartment. Thus, the stored food item remains fresh for longer. Also, they do this uniform
cooling 35% faster than the conventional cooling system.
Archaic models of refrigerators usually come with a single fan which takes the burden of cooling
both—refrigerator and freezer. But most of the new Samsung, Godrej, and Hitachi refrigerators
come with a dual fan system which enables independent cooling of the refrigerator and freezer
compartments. Using two separate fans, it effectively circulates the cold air throughout the
refrigerator. Thanks to Dual Fan Air Jet technology, premium Hitachi refrigerators are capable of
cooling the refrigerator even in the high ambient temperature of 60°C.
3. A Perfect Blackout Backup with Cooling Gel, Cooling Wall, and Insulated Capillary
Power cuts and load shedding is commonplace in India, especially in distant towns and villages.
Since refrigeration generally works 24×7, it is a home appliance most susceptible to the erratic
blackouts. Power cuts poise two problems for the refrigerator. First is the spoilage of food in case if
power cuts persist for a longer duration of time. Second is much more hazardous—damage to the
refrigerator due to voltage fluctuations. Modern refrigerator armed with technologies like cooling
gel can assuage the impact of power cuts. Most of the modern refrigerators from
reputed brands like Samsung, Whirlpool, Godrej etc. comes with a cooling gel, which is released in
the form of cool gas, which is then circulated inside the refrigerator to keep it cool for several hours.
Stay Cool is a cooling gel technology from Godrej. Stay Cool keeps the food well frozen for few
hours without power, and keep the freezer compartment cold even in the absence of electricity.
This means even ice cream kept inside the refrigerator won’t melt for few hours in case of
blackouts.
Samsung is the first manufacturer in India to come with a Cool Wall inside the refrigerator—an
especially designed wall which retains cooling even during power cuts for several hours. It
beautifully compliments the Cool Pack—a cooling gel technology, to keep the food items inside the
refrigerator chilled for up to 12 hours during the power cuts.
Besides the usual cooling gel modern direct cool Whirlpool refrigerators also come with insulated
capillary technology. Now, ordinary refrigerators come with the capillary that provides refrigerant
to the freezer, loses the cooling when exposed to the environment (during the door opening) but
the Whirlpool’s insulated capillary technology surrounds the capillary with the super cold gas. With
this technology, the freezer achieves the cold temperature as low as -26oC. Insulated capillary
technology helps to retain the freezer’s cooling even during the power cuts for up to 12 hours.
Similarly, in Haier refrigerator to compliment the effect of cooling gel, inner edges of the
refrigerators come with diamond shape design. The main benefit of this design is that it slows down
the process of ice melting. This becomes a very useful during the power cuts, helping to prolong the
cooling retention period.
4. Spacious and Customizable Interiors
The modern refrigerator comes with a lot of options and styles to store the food items with
complete flexibility, in form of shelves, crispers, chillers, bottle holders and wine racks.
For those who don’t know, crisper is the bottom-most compartment of the refrigerator used for
storing vegetables and fruits. Whirlpool offers a gamut of crisper types and designs:
Fresh & Sort crisper: A crisper style wherein a mini-crisper is given inside the main crisper. This is
done to sort the type of stored material. Fruits can be stored inside the mini crisper while rest of
crisper can be stuffed with vegetables.
Twin Seal crisper: A simple crisper style to separately allocate space for vegetables and fruits
Trizone crispers: To sort vegetables into three different zones to maintain freshness and moisture.
This way even vegetable can further be sorted, and the intermixing of odour’s can be avoided.
3. Another important feature of modern Whirlpool refrigerator is the adapt shelves. They offer a great
flexibility for adjusting shelves. Its zigzag shape holder is flexible enough to adapt to various kind
and size of storage. It is one of the most customizable ways of managing the space within the
refrigerator easily.
Vegetable crispers given in the new high-end Haier models are roughly 50% bigger than the
conventional ones. An important utility of this crisper is that it can be easily removed even if the
space for opening the door is less, thanks to its 90 Degree Contour door design. This would be a
boon for the users who plan to install their refrigerator in a place where the complete opening of
the door would be difficult.
Godrej’s new series of double door refrigerators come with a unique polybag suspender with hooks
to conveniently hang the frozen food items. Also, few models from the premium NXW series come
with smart collapsible wine rack capable of holding 5 bottles.
5. Usage of LED Bulbs for Brighter Lightning with Energy Saving
The lighting system in most of the modern refrigerator has been replaced with LEDs. Modern
refrigerators from Samsung are equipped with new LED lighting which is not only slimmer but also
softer and much more energy efficient. As they occupy lesser space, they help in increasing the
usable fridge space for storing the perishables. This LED lighting system emits 10 times lesser heat
than the ordinary bulbs. This means food would remain much more immune to temperature swings
owing to the lighting arrangement. This LED comes with eco-technology which consumes 20 times
less power than conventional light bulbs.
LG’s flagship refrigerator LG Signature comes with premium Lumishelf LED lighting under each shelf
to give brighter and clearer view of refrigerator’s interior even if it is fully stuffed. The LED bulb used
by LG helps in reducing the energy consumption by up to 77%. The best part is that they are
around 26 times more durable than the conventional lamps found in older refrigerators. Consumers
can save a good sum of money as they consume much less amount of energy while having a good
longevity, meaning lesser repairs and replacements.
Apart from the LED lighting, Godrej refrigerators come with another advanced feature, motion
sensing lights that can detect any movement. Based upon on the detected action, it illuminates the
area where the user is looking for food or trying to arrange the food items.
6. Digital Inverter Compressor for Optimized Refrigeration, Energy Saving, and Noise
Reduction
Digital Inverter technology is arguably the most important innovation, pushing the boundaries of
water refrigeration technology. To know the significance of having digital inverter compressor, we
first need to know how conventional compressor works. Compressors in the old/cheap refrigerators
come with single speed motor. They are either “on” or “off” based on the temperature in the
refrigerator. Such compressors are designed to work incessantly at the peak load conditions (for
high temperatures in summers), which means that they run at peak load even in winters when the
cooling requirement is less.
As an upgrade to these simple compressor manufacturers has come up with inverter compressor
technology. Samsung and LG lead the pack in this department as they come with most advanced
inverters and are the only two brands giving inverter technology even in single door refrigerators.
Samsung arms its compressor with a smart digital inverter with 7 adjustable speeds to suit different
cooling demands. Working of the compressor with inverter technology is analogous to the car
accelerator. When the speed required is more, the acceleration is more, and when it is less, and
then the acceleration is less. This makes sure that during the summer season when the cooling load
is more, the compressor works at the peak capacity taking more electricity. But during winters when
the cooling load is less, the compressor runs at the lower speeds thereby consuming less electricity.
4. Even during summers, the night temperature is less than the day temperature. Thus, electricity is
saved even during the late evenings when compressor can run at a lesser speed.
LG, on the other hand, provides even more advanced and energy efficient Inverter Linear
Compressor which saves up to 32% energy by adjusting cooling power depending on the amount of
food loaded in the refrigerator. Because they use piston drive in place of the reciprocal one,
refrigeration performs with optimal efficiency leading to big energy savings. This compressor
operates within a temperature range of ±0.5°C—almost half the temperature variation as compared
to the ordinary compressor. Compressor comes with fewer friction points that greatly reduce noise
(up to 25%).
