1 Dual fan cooling system

Hitachi 's new generation cooling system combines two innovative technologies, the inverter compressor and the dual fan system, which effectively cools even without wasting energy.

+ High efficiency, compact and compact inverter compressors

Inverter compressors are designed with high precision and durability to flexibly adjust the cooling mode according to many levels from high to low, depending on the temperature conditions inside and outside the refrigerator, ensuring the temperature. the inside of the refrigerator is always at the ideal level.

+ Dual fan system for more efficient cooling

Dual fan system helps to cool the freezer or freezer compartment or both compartment independently, powerfully and quickly. Dual fan cooling system applied on Hitachi refrigerators to bring maximum cooling efficiency while saving energy effectively. By designing two separate blowers for the freezer and cooler compartment while still using the same compressor, cold air is circulated from the freezer compartment down to the cooler compartment and then upwards.

This independent cooling will help the refrigerator operate efficiently while saving energy. For example, when the freezer compartment reaches the maximum suitable cold, the thermosensor in the refrigerator will detect and automatically adjust by stopping the supply of cold air, which works similarly with the cooler.

Thus, the temperature of the two compartments is handled independently, maintaining the ideal temperature, in no case the refrigerator is over-cooled, leading to wasted energy or insufficient cooling as before.

2 Breakthrough cooling with Vacuum Compartment

At room temperature, food spoils very quickly because oxygen reacts with organic substances in the food. With a small pump specially designed in the Vacuum Compartment creating an ideal storage environment with a vacuum pressure of 0.8 atm, prolonging storage time for longer, fresh foods while remaining intact Longer quality and freshness compared to conventional storage methods. This is the most advanced food preservation technology today.

In addition, the Quang Hoa Preservation technology in the Vacuum Chamber uses the light from the LED to prevent gas exchange to lose nutrients of vegetables and to limit protein breakdown in meat, fish. Bacteria, strong deodorization, help the space inside the refrigerator completely fresh.

The sensor in the Vacuum Compartment has the ability to recognize and automatically adjust the appropriate temperature for each type of food, helping them to be stored in optimal conditions. 

3 Frost Recycling refrigeration technology

Applied on large capacity refrigerators, Frost Recyling technology from Hitachi is a very unique innovation, allowing to recycle the cooling capacity without the need for a compressor.

Specifically, when the refrigerator reaches the right cold temperature, the compressor will automatically turn off, then the snow on the indoor unit will be used to keep the temperature low. The combination of high efficiency compressor and advanced vacuum insulation system helps the refrigerator to operate efficiently while saving energy.

This process operates on 100% generator operation, re-used cold steam and maintains a constant temperature without loss. The effect of this heat retention process is that thanks to Hitachi's special cold air curtain, this cold air curtain creates a steady stream of cold air, circulates it evenly and keeps it in the vegetable compartment, and then recycled. for cooling without a compressor.

Frost Recycling technology, because it does not use a compressor, saves significant energy, is a highlight of Hitachi's environmental mission, in addition to achieving the most complete ecological efficiency in refrigeration technologies. up to now.

4 Air Jet Flow cooling technology

Air Jet Flow is a refrigeration technology applied to Hitachi's small capacity two-door refrigerators. This technology by using ventilation cells (also known as drains) pushes cold air around the cabinets, thereby helping to cool more efficiently.

The special feature of this technology is that lies in the layout of the wind drains, the manufacturer has made very sophisticated calculations about the location of these drains to ensure enough repelling cold air. uniformly to every position, every corner in the cabinet without being interrupted by any obstacles. As a result, even if there is a sudden power outage for quite a long time, when restarted, the refrigerator quickly reaches the cold needed to ensure food does not spoil.

5 Minus Zero cooling technology

Minus Zero is a refrigeration technology applied on Hitachi's small-capacity, two-door refrigerators, with slightly larger capacity than Air Jet Flow technology. Minus Zero works based on equipping a heat-radiation aluminum sheet (also known as a cold blister) that absorbs and emits more refrigeration, while consuming the same amount of electricity.

Specifically, this blister works similar to the fact that you put a large ice cube in a bucket to chilled fresh food, which will help your fridge maintain the necessary coolness and be homogeneous between locations. in the cabinet, thereby helping the preserved food to be more delicious.

In addition, the Minus Zero technology  also brings a very good moisturizing effect in the cabinet, so your vegetables, tubers and fruits will not lose water and ensure nutrition for many days.
