Types Of Fridge

In the market, different types of refrigerators are available. We have put them together to suit various types of kitchen styles! Before selecting the one, you must check out all types.

Single Door Refrigerators

As the name itself suggests, the refrigerator has only one door for the fridge and freezer. It is a basic style and common in many houses. If your budget is minimal, then a single-door refrigerator is the right choice. It provides high cooling with maximum volume for the storage of food, fruits, and vegetables. Most importantly, These compact refrigerators are suitable for small-sized families. 

It comes in different sizes and capacity, plus at a budget-friendly cost. The single door refrigerator is also known as Direct Cool Refrigerators. 

Double Door Refrigerators

The Double door refrigerator is one of the common types after a single door. There is a fresh food items section under the freezer section that makes it ideal for small kitchens. The freezer section is usually on the top in old models of refrigerators, but the latest models arrive with a bottom mount freezer compartment.

The bottom-mounted refrigerators avoid bending work to take out things. It is usually frost-free; it arrives with special heating functions that don’t let the frost collect. It comes with multiple adjustable drawers and a container to sort your groceries. These refrigerators contain a heating element that prevents frost formation. Thus they are also known as Frost Free Refrigerators.

Furthermore, it comes with a storage capacity range between 300-700 litres that meet a standard nuclear family’s daily needs.

Side by Side Refrigerators

This side-by-side door refrigerator has more space for storing and flexible options than others. Further, it takes up a lot of space in your home. This is usually enormous and comes with a water dispensing unit. It helps to gulp down the cold water without opening the fridge. These refrigerators consume more electricity but give better performance. 

It is also known as a “French door side refrigerator” with a freezer on the left or both sides. Some models have a traditional style on the right side. 


How to Choose the Best Refrigerator in India 2021?

You need to know the features and technologies before jumping into the pool of products—this buying guide helps in picking the refrigerator in India.

Capacity

The capacity of the fridge is one of the main factors that affect your choice. Depending upon the storage requirements and family size look for the size and capacity of the model that you want to buy. For a family of 3 to 4 members, a fridge with storage range from 200 to 300 L is perfect. 

Suitable ForCapacityDoor Types
1 person50 to 250 LitersSingle door
2 to 3 people250 to 300 LitersSingle door, Double door
4 to 5 people280 to 350 LitersDouble or Three Door
6 or more people565 to 630 LitersFrench or side-by-side

Defrosting

All refrigerators need cold air conditioners like circulation in their cells divided into two types – frost free and direct cool refrigerator. 

Direct Cool Refrigerator: In a Direct cool type refrigerator, the natural air circulation is used throughout the appliances. It produces coolness by using a natural convection method. So, you can’t control the cooling setting distribution inside the refrigerator. In result, it leads to uneven cooling, and in the output, it creates a collection of frost. The freezer has to defrost to avoid the ice growth regularly.

The fridge with this technology comes in a Single Door Refrigerator. They demand less electricity, low maintenance. So, for a small budget and less space, it is the best option.

Frost Free Refrigerator: The frost-free technology works on the law even distribution of chilled air inside the appliance by electric fans. There is no formation of ice. However, it consumes more energy than others but gives extended duration. 

Inverter Technology

This is an essential factor of a refrigerator. Most people suffer from high electricity bills, power failures and load shedding. The refrigerator with inverter compressor technology can be more expensive but saves a lot of electricity bill.

With Inverter Technology, the compressor works on different speed levels. It gives a better result. When the temperature falls under bearing levels, the inverter starts to switch off a compressor on lower capacity. But it provides maximum capacity when cooling is required.

Cool Box

When power cut occurs, the Cold Box is another feature that works well for some time. The modern machines come with the technology of Cool Box. It permits the refrigerators to stay crisp and fresh when light has been gone for long hours. After the power cut of 2-6 hours, it will remain intact with the milk, veggies and fruits. For the area where power cuts are often, they need to get a hold on this method.

Eco-friendly

The common refrigerant in practice is CFC. It causes damage to the environment as well as some health hazards. It attacks the atmosphere where you placed it. Some of the Refrigerators have environment-friendly coolants. The best alternatives for the coolants are R134a, R600a. They are never toxic to nature but gives long life.

Air conditioners also use the coolants that are green substance never hurt the planet. For the clean air, we can take the Air Purifiers unit that works on the Refrigerants.

Stabilizer Free Operation

The voltages changes are an unknown thing to the households, so you need a Stabilizer. They generally protect against the short circuit and voltage gain or drop. As technology becomes advanced in recent years, now the Refrigerator in India comes with an inbuilt stabilizer. 

These built-in Stabilizers control the voltages variation and a sudden surge of tensions. Without buying the external Stabilizer reduces the cost and increases the energy efficiency of your device.

Conversion Facility

The standard fridge to freezer ratio is around 8:2. With this refrigerator, you can make stocks of vegetables and fruits in the main fridge unit. In this way, the freezer is almost unusable for vegetarians. However, when you lack space in the freezer, then there is a technology that fulfils the demand for space.

With the conversion amenity, you can change your freezer into a fridge that helps you to put regular things. This is the best decision for those people who have space crunch issues.
