Hello everyone, I'm Caribbean Cowes.
It's a pleasure to meet you all.
The old refrigerator in Coase's house had been in use for almost a decade, the refrigeration effect was getting worse and worse, and it often made a humming noise, and I asked the repair master that it had no repair value, so I decided to buy a new refrigerator. This time, I discussed with my family and decided to buy a better refrigerator, which is not only more convenient to use, but also has a longer service life than cheaper products.
As a hitachi powder for many years, the first choice to buy a refrigerator is definitely Hitachi's products, after my unremitting squatting, I finally grabbed the preferential price of the purchase in Hitachi's live broadcast room, bought my favorite Hitachi R-HW540NC refrigerator, the first reason for choosing it is the super high value, and the second reason is good freshness. The refrigerator has been used for a while, and today I would like to present you with a freshly baked use review.
[This guy's appearance is very good]
Hitachi R-HW540NC refrigerator refrigerator belongs to the medium-sized Japanese classic multi-door refrigerator, the width, depth and height are 650 * 699 * 1833mm, in the refrigerator industry belongs to the small and not small players, whether in the kitchen or the restaurant can be. If your home has not been renovated, I suggest that you can make a built-in cabinet, put the refrigerator in, maximize the use of space, not to mention, do not make the refrigerator look abrupt.
Hitachi R-HW540NC refrigerator is made of crystal glass, the biggest feature of this material is that it is good-looking, durable and easy to take care of. The entire surface looks both transparent to glass and reflects the surrounding scene like a mirror, making the space appear larger through mirror reflection. At the same time, the hardness of this material is very high, it is difficult to leave scratches in daily use, and it is very convenient to clean, whether it is dust or oil smoke, as long as it is gently wiped with a wet rag. The only thing that needs to be noted is that when you use it, do not bump hard objects vigorously, otherwise it is easy to cause mirror damage
Unlike the traditional refrigerator adjustment button distribution, all the operation buttons of the Hitachi R-HW540NC refrigerator are concentrated on the refrigerator panel, and any temperature mode adjustment can be carried out here, and the touch button is very convenient to use, even the elderly and children can easily operate. At the same time, the entire operation panel uses an explicit and implicit design, that is, when no one uses it, it is not visible at all, and the surrounding is transparent glass, only when the finger points up, these buttons will be revealed, very scientific and technological.
【Small body is very easy to wear】
Compared with the same type of products on the market, the body size of the Hitachi R-HW540NC refrigerator is really not large, but the capacity has reached about 520L, which is much larger than many friendly products. It can achieve a small volume and large capacity, mainly thanks to Hitachi's VIP vacuum insulation and insulation technology, that is, adding vacuum insulation materials to the refrigerator wall, using the characteristics that heat is not easy to conduct in the vacuum, isolating the internal and external heat exchange, and bringing better thermal insulation effect. Compared with the traditional polyurethane foam, this thermal insulation material is much lighter and thinner, but the thermal insulation effect is higher, the refrigerator wall is thin, and the internal space is not left out?
For example, Toshiba's GR-RM429WE-PG2B3 refrigerator, the overall size and Hitachi R-HW540NC refrigerator is similar, the width and depth height are 600 * 698 * 1833mm, but the overall capacity is only 409L, which is about 100L smaller than 540; for example, Siemens' KF86NAA95C refrigerator, the width and depth height are 811x736x1830mm, all of which are much larger than hitachi 540, but the overall capacity is only 472L. In the case of larger volumes, less usable capacity is available. This is the technical advantage brought by VIP vacuum insulation materials.
Hitachi R-HW540NC refrigerator internal storage division is very meticulous, a total of three large areas of cold room, freezer room, vegetable and fruit room, there are detailed divisions under each large area, and listen to me nagging.
Cold Room: Hitachi R-HW540NC refrigerator has a cold room volume of 266L, with a left and right double door design, four floors of space inside to place dishes, a separate water storage box and a closed vacuum ice greenhouse. There are seven shelves on the refrigerator door, and the storage space is very generous.
Freezer: Hitachi R-HW540NC refrigerator has three parts, namely the automatic ice room, the upper freezer and the lower freezer, with a total space capacity of 155L. As the name suggests, the automatic ice room is the place used to prepare ice cubes, and the specific things will be said later. The upper ice room is mainly used for rapid freezing, the lower ice room undertakes more storage functions, in order to maintain hygiene and easy to take, the lower ice room is divided into three layers of space, using sliding drawers to divide, can be used to store different sizes of kinds of ingredients, such as pork, fish, quick-frozen food, can be stored separately.
Fruit and vegetable room: Dishes purchased in the past are difficult to handle, either placed in the refrigerated area to occupy a space that is not abundant, or placed outside to affect the shelf life. The Hitachi R-HW540NC refrigerator has specially added a vegetable and fruit preservation area, which is located at the bottom of the refrigerator with a space capacity of 99L, which also adopts a multi-layer design, which can store different types of vegetables of different sizes, suitable temperature and relatively confined space can effectively extend the freshness period of vegetables and fruits, prevent the loss of nutrients and moisture, and retain a better taste.
【Black Technology Blessing】
In addition to being able to install, hitachi R-HW540NC refrigerator preservation capacity can not be underestimated, the whole machine uses Hitachi's iconic four preservation technology, including moisturizing low temperature refrigeration, vacuum ice temperature preservation, platinum catalyst sleep, rapid freezing, etc., the following I will talk briefly from the principle and effect.
Moisturizing low temperature refrigeration:
A lot of food in the refrigerator will gradually dry, resulting in poor taste when eating, in fact, the main reason is that the refrigeration process of a large amount of water loss, the taste and nutrition of the ingredients themselves are lost a lot. Hitachi R-HW540NC refrigerator moisturizing low temperature is to add moist air in a suitable low temperature environment, so that the ingredients are always in a high humidity environment, to avoid flowing air to take away the moisture of the food itself.
In this environment, the moisture and nutrition of the food have been retained to the greatest extent, and the taste is naturally better when eaten again. It is said that in this high humidity environment of about 2 ° C, food can be stored well without the use of plastic wrap, and it is easy not to spoil and spoil. However, the specific situation, or wait for my follow-up use when the experiment it ~
Vacuum ice temperature preservation:
This technology is relatively famous and has been applied by Hitachi to many of its own refrigerator products. The so-called vacuum here does not refer to the real vacuum, but in a confined space added a small vacuum pump, after opening the space to extract the air in the space, so that the atmospheric pressure in the space from a standard value to 0.8 standard value, in this case the external air can not enter the interior, to avoid the breeding of bacteria, while the internal air also because of the low pressure and slow down the flow, to avoid the oxidation of food. In the micro-freezing state of minus one degree, the preservation effect is naturally outstanding.
This function is relatively simple to experiment with, I directly bought a fresh meat ham, and then cut two pieces of equal thickness, and placed them in the ordinary refrigerator and vacuum ice greenhouse. After an hour of observation, you can see that the two pieces of ham are basically not much different, and the color has not changed significantly; five hours later, when you observe again, you can see that the difference between the two is more obvious, the ham inside the ordinary refrigerator has become dark red, the surrounding circle has become hard and curly, and the ham in the vacuum ice greenhouse still retains its original luster, and there is no obvious discoloration.
Platinum catalyst preservation:
The platinum catalyst function is also one of the killer skills of Hitachi's refrigerator products, which is to use a special component to continuously produce platinum catalyst factors, which will float around inside the refrigerator, look for harmful gases such as ethylene, and then decompose them into harmless carbon dioxide and water. Many people may not know much about ethylene, this gas is often used for the ripening of fruits and vegetables, so that food can grow faster, and excessive amounts will lead to rapid food spoilage. As long as one of a large number of fresh fruits begins to emit ethylene, it will quickly affect other fruits, causing everyone to break together, which is probably the a mouse spoiled a pot of soup in the fruit industry.
The carbon dioxide and water decomposed by the platinum catalyst are not useless, for fruits and vegetables, the importance of water is not necessary to say more, and carbon dioxide is actually very important in the storage process. If the concentration of carbon dioxide in the space is relatively high, it will inhibit the respiratory movement of vegetables and fruits, so that they enter a state of sleep, in which the rate of nutrient loss of vegetables and fruits will be greatly slowed down, and more juice and nutrients will be retained when eating.
Rapid Freezing:
This function is mainly realized in the upper freezer mentioned above, the principle is actually not complicated, the first is to reduce the temperature of food with the help of a powerful refrigeration system, and the second is to quickly absorb the heat of the food itself with the help of a special large aluminum plate, and the two-pronged approach can make the temperature of the food drop rapidly. The reason for this design is that if the freezing rate is slow, larger ice crystal particles will form, which will puncture the food cell wall during the extrusion process, so that the food water is lost a lot.
If the refrigeration speed is faster, it can cross the temperature band that is easy to produce large ice crystal particles, and quickly enter below -5 ° C, and at this temperature, smaller ice crystal particles will be formed inside the food, which will maximize the preservation of moisture and nutrients in the food cell wall, and the taste will be better when eating.
【Automatic ice making is more stylish】
Hitachi R-HW540NC refrigerator another feature that makes me very excited is automatic ice making, as a fat person who weighs 160 pounds of heat, summer is really very difficult, sweltering weather often makes me sweat, especially when I come home from outside, a cold drink is really like a life-saving straw, so I used to freeze a little ice cube in the refrigerator, so I can use it at any time. But now with the automatic ice making of hitachi R-HW540NC refrigerators, you don't have to get it yourself anymore.
Hitachi R-HW540NC refrigerator has a water storage box in the refrigerator, as long as the drinking water is poured in, the water will flow down the pipeline to the automatic ice making chamber below, where it is made into crystal clear ice cubes, which can be used whenever needed. In order to avoid the growth of bacteria, the automatic ice room of hitachi R-HW540NC refrigerator has also added an automatic cleaning function, and after opening, there will be a high-speed water flow to wash the pipeline, taking away all the possible slime bacteria, while ensuring that no moisture will remain in the corners and other parts. As long as you clean it regularly, you can keep the ice clean. By the way, if you don't use the ice making function much in winter, the rapid ice making room can also be used as a small freezer
【Heartfelt recommendation from individuals】
Well, listen to me so much, I believe that everyone has a lot of understanding of hitachi R-HW540NC refrigerator, from my use in just a few days, 540 is really a good refrigerator: outstanding appearance can adapt to any kind of decoration style; plenty of space can meet the needs of a family of 3 to 4; a strong preservation function can preserve the original nutrition and taste of food as much as possible; plus the thief has a stylish automatic ice-making function, which is really a very suitable choice for me.
