Hitachi's home appliance business is mainly concentrated in Japan, and the market share of refrigerators has remained among the top three in Japan. Hitachi refrigerators are leading in technology, and have won two energy conservation awards from the Ministry of Economy, Trade and Industry in the three years from 2014 to 2016 for their unique frost energy reuse technology. At present, Hitachi has not established a refrigerator production line in China, and the Hitachi refrigerators sold in China are all imported from abroad, all of which are high-end air-cooled inverter refrigerators, with high prices and no products below 10,000 yuan.
 
Hitachi refrigerator black technology emerges in an endless stream, and it has achieved the top in the industry in many aspects. The distribution of its cutting-edge functions is also extremely balanced, and it has made achievements in the direction of freshness, heat insulation, energy saving and intelligence. Fruit and vegetable preservation and noise control are far higher than other Japanese brands.
 
Exclusive preservation technology
 
Freshness preservation is the core purpose of refrigerators, which are divided into two aspects: storing vegetables, fruits and meat, and most refrigerator brands are commendable for making breakthroughs in one aspect. However, only Hitachi has truly achieved the flowering of meat and vegetables, and has launched two high-end preservation technologies of platinum decomposition ethylene and vacuum ice temperature.
 
For vegetables and fruits, most brands such as Panasonic use humidification to delay the loss of water from foodstuffs, which cannot inhibit the nutrient consumption of plant cells and the growth of microorganisms. Hitachi uses platinum decomposition technology to decompose organic gases such as ethylene released by fruits and vegetables, increase the concentration of carbon dioxide in the fruit and vegetable area, inhibit the metabolism of vegetables and microorganisms, and prolong the freshness time of food.
 
For meat, Mitsubishi Electric uses -5 °C instant freezing technology, Panasonic uses -3 °C micro-freezing technology, and Siemens uses zero-degree preservation technology, which essentially uses not to freeze meat thoroughly and retain better taste and nutrition, and the disadvantage is that it is not as long as low-temperature freezing. Hitachi's vacuum ice temperature is based on 0°C micro-freezing, which extracts part of the air from the storage chamber to reduce the oxygen concentration and inhibit the reproduction of microorganisms. The method of keeping food fresh by pumping to negative pressure through a small vacuum pump requires extremely high details such as storage compartment tightness and pressure control, and only Hitachi has launched a refrigerator product with this function.
 
For families who are inconvenient to buy groceries and like to stock up on ingredients for a week, freshness is the most important choice factor, and Hitachi has the advantage of locking freshness technology that other brands cannot match.
 
Space and energy savings
 
Hitachi refrigerators are designed to be wider and larger than other brands, and the thickness of the cabinet is extremely thin, and the internal space utilization rate is higher. Most refrigerator insulation layers are made of cyclopentane or cyclohexane foam, which is thick and uneven. Most of Hitachi's refrigerators are made of FLEX vacuum insulation, which has a slim cabinet and better heat preservation. This insulation material can also be bent into complex shapes according to different parts, and the thickness of some parts is reduced by 1/3 compared with the polyurethane foam layer, which is the most high-grade and cost-effective insulation material on the market.
 
In terms of energy saving and consumption reduction, Hitachi's exclusive frost energy reuse technology converts the frost on the condenser into moisturizing cold flow and recycles it for refrigeration and preservation, and the compressor is suspended while the refrigeration is still running, achieving excellent energy-saving effects.
 
Side-by-side refrigerator
 
The Hitachi refrigerators sold in China are all imported from abroad, but the side-by-side, three-door, and cross-door refrigerators are all imported from Thailand, and the higher-grade Japanese multi-door refrigerators are imported from Japan. In terms of technology and materials, the workmanship materials of Thai Hitachi refrigerators are not inferior to those made in Japan.
 
The side-by-side refrigerator is currently a popular refrigerator style, frozen on the left and refrigerated on the right, the product is wide and large, and the atmosphere is decent. However, due to the small number of partitions, and the large area of each door opening, the heat enters more, and the actual power consumption is often more. The three doors on the right side are divided into upper and lower doors, which are relatively more energy-efficient.
 
Some Hitachi refrigerators have an automatic ice bar function, which allows you to get ice, crushed ice or ice water at the touch of a button without opening the door. This ice bar function is extremely popular in Japan and South Korea, and it is a combination of refrigerator and water dispenser. However, this function does not conform to most Chinese families who are accustomed to "drinking more hot water", and the conventional frozen layer can also complete the basic ice making.
 
Japanese multi-door refrigerator
 
Hitachi's Japanese multi-door refrigerators have a wide range of products and a clear product line, which can be divided into small-capacity S series, fresh-keeping SF series, delicious quick-frozen G series, and electric door X series. The first two are made of metal sheet steel panels, and the last two high-end series are made of tempered glass. All products are equipped with antibacterial and deodorized filter system, which effectively eliminates sulfides, amines, aldehydes, acids and other odorous small molecules. The SF series comes with the aforementioned vacuum ice temperature and platinum decomposition ethylene dual preservation technology, and the price is about 20,000 yuan.
 
The delicious quick-frozen function is an upgraded feature of Hitachi's high-end products. This function is to design an independent large aluminum disc in the freezer, through the rapid thermal conductivity of metal, quickly absorb food heat, and quickly pass through crystallization to generate a temperature zone, this kind of quick freezing can effectively reduce the destruction of food cells, and maintain the nutrition and flavor before freezing to a large extent. The series also has a touch electric drawer function, which will automatically open the drawer with a crawler when you touch the drawer, which is high-end and convenient.
 
Hitachi has a large number of Japanese multi-door refrigerator products, leaving consumers with a comfortable choice. Platinum catalyst, vacuum ice temperature and other basic preservation functions are complete, and all of them are equipped with antibacterial and deodorization filters, and the lower limit is extremely high. Friends with a large amount of reserved space in the refrigerator can consider more.
 
Flagship refrigerator
 
The X Series is the culmination of Hitachi's product portfolio. Flagship refrigerators pay more attention to intelligence and a sense of technology. The refrigerated area is opened by a touch slide, and the double doors of the refrigerated area above are gently opened with a simple swipe of your fingertips, creating a unique ceremonial beauty. The lower freezer drawer is also equipped with an electric opening function, and the opening sensor recognition is sensitive and accurate, so there will be no trouble of accidentally touching and opening it in daily life. The series also uses the same mirrored glass panel as Panasonic, which looks like black amber lined with reflections, with a light and shadow effect that expands the visual space.
 
Hitachi products are all original imports, quality control and design are excellent, and families who like high-end products and prefer large capacity can buy Hitachi products. In this regard, Hitachi and Toshiba are positioned very similarly, focusing on the high-end market. Panasonic, on the other hand, takes care of the mid-range model and takes care of more consumer groups.
