Design and features
As a four - doorway electric refrigerator deep freezer , the top of the Hitachi R - WB640VGB1 is commit to one large ( 372L ) area for food . That ’s an epic amount of space , particularly as it ’s spread over the electric refrigerator freezer ’s full breadth . There are three shelf inside , with two of them being height - adjustable .
There ’s enough space to stand up declamatory jolt , but big items , such as bottle of drink , will demand to be laid flavourless . Still , the place on crack means that it ’s wanton to squeeze in bulkier food , such as a fresh Anna Pavlova or even a cooked volaille .
There are pockets in both of the electric refrigerator doors . The one on the left hand has three pockets , so it can take taller point on the two lower shelves , including quad for 1L drinks cartons and the like . The door on the right has four pockets : the bottom one can take tall items , but the top one are best saved for short one .
Inside the electric refrigerator , there ’s a multitude of drawers , including two for vegetables and one with selectable humidity mastery : the luger moves between Dry Food and Vegetable .
There ’s also a thin slide - out drawer , which could be utilitarian for keeping cucumbers or leeks , but that infinite could have been better used by take a leak the draftsman next to it slimly wide .
heart to this model is the vacuum compartment , where the zephyr is removed when the drawer keep out , maintaining a 0.8atm pressure . Less atomic number 8 means that food wo n’t dehydrate or mislay its good as fast , making it ideal for salt away novel kernel and fish , slices of kernel and cheese , and even cut vegetable .
There ’s a satisfying hushing when opening this compartment , like Darth Vader come out of his bedroom .
The fridge also has a water container , which is used to make crank cube for the deep freezer and is not for dispensing chilled water system . It intend that there ’s no need for plumbing .
Underneath , there are two threshold to reach the Deepfreeze compartment . Both sides are identical , with one tray and two drawers . The compartment on the right also houses the ice cube tray . I find out the drawer bountiful enough for everyday staples , include stock-still pizzas .
The compartment on the left is a Selectable Zone , which can be arrange up as a right deep freezer , an extension of the fridge , a Chill zone ( 1 ° C ) , or a Soft Freeze area ( -3 ° C ) . With Soft Freeze , meats are stash away at carry on temperatures but can be misrepresent straightaway before thawing . If you ’ve got intellectual nourishment lined up for a political party , this can be a useful zone for preserving it while bear it quick to go .
The Selectable Zone is manage via the controller panel on the front , which also let you set the vacuum zone to your choice of 1 ° C , -1 ° C , or off .
electric refrigerator and freezer temperatures can be adjusted severally , although there are no temperatures save on the icons , so I had to pertain to the manual of arms to sic my preferred option of 4 ° C and -18 ° C for the fridge and freezer , severally .
Performance
I loaded the Hitachi radius - WB640VGB1 with ice block and then installed temperature sensor throughout to supervise temperature . To simulate real economic consumption , I used automatic room access unfastener , which open and shut the fridge door at regular interval .
I found the electric refrigerator had an median temperature of 3.63 ° C , just 0.37 ° coulomb ice chest than the target area temperature of 4 ° snow . The received deviation was + /-0.84 ° C from the average – anything under 1 ° C shows that temperatures are stable and do n’t waver much .
There was n’t too much magnetic declination inside , either : the top was a cutaneous senses colder at an norm of 2.97 ° ascorbic acid , while the bottom of the electric refrigerator was a bit warmer at 4.26 ° C , but both were within the mountain range I ’d carry .
It was similar with the deep freezer . An average of -18.77 ° speed of light was just 0.77 ° C colder than the primed temperature . The standard deviation was a little higher here at + /-1.37 ° degree Celsius – although that ’s only just over the nonsuch of 1 ° speed of light fluctuation .
I screen the vacuity compartment by adding a bowl with 30 g of infant spinach plant . Out of the promotion , spinach usually lasts a daytime or two before it dry up . After two days in the vacuum compartment , the Spinacia oleracea look as effective as it did when went in . A hebdomad later , the prickly-seeded spinach had shrivelled a fiddling , but it maintained its colour and grain and was actually alright to eat .
That ’s staggeringly impressive and read how much longer the vacancy compartment can maintain nutrient for .
The downside is the running cost . farad - rated , the Hitachi R - WB640VGB1 uses a massive 400kW of office a year , which works out at 24p per liter of quad , or a annual cost of £ 136 . If you ’re sensitive about how much vigor your home uses , a minuscule , more effective fridge , such as theHotpoint H9X 94 T SX , may be a safe option .
This is a pure no - hoarfrost fridge freezer , so it wo n’t need to be defrosted . I did n’t notice any ice build - up during testing .
