High-End Refrigerators?

Posted by jsecunda (My Page) on

Hi folks - I just installed my new Bluestar. As a cook, I can understand why it is "better" than the Wolfs and other residential "commercial" stoves I have worked on.

I'm also in the market for a new fridge and would appreciate your insight on the topic. I've done a search on 'high-end vs. standard refrigerators' but I don't see that it's been addressed directly. Even dealt with implicitly, the subject chronically generates some touchy exchanges in thsi forum. However, I'll ask anyway.......

Other than aesthetics, are there practical advantages to a free standing "high-end" refrigerator over the basic Whirlpool, GE etc.(SubZero, Leibherr, others)? Do the high end models feature better layout, build quality, durability, length of food freshness etc.? Or is the primary advantage aesthetic, with performance being approximately equal between the two?

Thanks for your thoughts on this-
JS

"are there practical advantages to a free standing "high-end" refrigerator over the basic "

free standing units aren't Generally considered "high end", but one advantage to the built in units (high end) is that they free up space in the walkways and aisles.

"Do the high end models feature better layout"

depends on who you ask - this is so very subjective and brand dependent that a general answer is not possible.

"build quality, durability," - high enders are generally better but it's not universal.

The value proposition is also a tough one because the high end one cost more than twice their reg. brothers and it's no shoo in that they will last twice as long and perform twice as well.

Bottom line is do not "stretch" to go high end. If you can realistically afford one then don't sweat it.

RE: High-End Refrigerators?

The major advantage to a high-end refrigerator-freezer such as a Sub-Zero is separate compressors for the freezer and refrigerator compartments. Stand-alone and lower-end refrigerator-freezers have a single compressor. The refrigerator compartment is cooled by circulating a measured amount of cold air from the freezer compartment into the refrigerator compartment. That works fine for cooling the refrigerator, but the problem lies in the fact that super cold air from the freezer is highly desiccated air. Consequently, food in the refrigerator tends to dry out unless tightly covered, and fresh produce tends to wilt quickly unless it's also wrapped very carefully.

A Sub-Zero refrigerator, on the other hand, has separate compressors. Air from the freezer and refrigerator compartments never mix. The refrigerator is cooled by a cooling coil behind the back wall of the refrigerator compartment. The air in the refrigerator compartment isn't fan forced over the cooling coils and the air is never super-cooled. Consequently, the air in the refrigerator retains a much higher relative humidity and food and produce don't dry out nearly as fast. Fresh produce, meats, cheese and eggs will stay fresher longer when not subjected to desiccated air that has been chilled to freezing temperatures. You also won't get ice cubes in the freezer that taste like the left-over garlic chicken stored in the refrigerator.

I've had both types of refrigeration. I can categorically state that food, produce in particular, will last longer and remain in better condition in a dual compressor refrigerator-freezer.


 o
RE: High-End Refrigerators?

Wa8b- Thanks for that explanation, especially the info about the relative humidity of the air. I knew that my Sub Zeros kept the food much longer than my old units but never really knew the reason. I've had a 501F and 501R since 1988 and hope they just keep chugging along forever.


 o
RE: High-End Refrigerators?

Not all high-end fridges have 2 compressors -- that's a point to be checked.

I think many of the questions posed can be answered by a trip to a big box appliance store and another that sells the high end merch. Some have both. Think car shopping.

You then can see for yourself and make your judgments, just as you did with the range.

I'm also not sure "better" is a good criteria because it can be so relative. F.ex. you love your Bluestar but a Wolf owner may think his range is better than yours.

I'd be looking at "better for me."


 o
RE: High-End Refrigerators?

wa8b hit a home run. Clear talk, about the most significant thing.
It's true that most of the threads about high-end don't deal with HOw it happens that stuff stays good longer.
It's because of better temperature regulation and Astronomically better handling of Humidity in the freezer air and in the fridge air.

I think a good alternative is to get separate devices for freezing and refrigerating. This is the subject in a few threads started recently. Air used to freeze things is not good to recirculate into the fridge compartment to keep things cool, since frozen air is dryer than it should be for a fridge. rococugurl already mentioned that some high-end have two separate Air circuits, operating on a single compressor that load switches between the two.

I also have had both types of refrigeration and "can categorically state that food, produce in particular, will last longer and remain in better condition" in a high-end refrigerator. Everything stays edible longer, and even taste is preserved longer.

fwiw a system known as "passive" keeps humidity at 99% in the fridge compartment. Only available in some of the imported fridges.


 o
RE: High-End Refrigerators?

Thanks for all the observations-very helpful. I had no idea how refrigerator/freezers actually worked-so, thanks for that, as well. So, it looks like on a regular unit)a single compressor cools the freezer coils, which then cools the ridge while dehumidifying its contents. If all standard fridges work that way, getting separate units for freezing and refrigerating seems problematic, unless the fridge is a dual compressor unit to begin with!


 o
RE: High-End Refrigerators?

I have 2 h-e fridges. 1 single compressor; 1 double.

Brand aside, the double will keep baby greens for 2 weeks while they go within 5 days in the single.

But, that begs the question: who wants to eat 2 week old lettuce? So there's no holy grail here IMO.

One of the best fridges I've used was an old Amana in a rental house. I grew up with commercial -- that freezer was so cold my dad would complain that the ice cream was too hard.

Seperate units are great if space and budget permits. After that, seems to me it's about use, style and interior org (but I'm an end-user not in the appliance biz).

In general, h-e brands that get good reports here include (in no particular order) SZ, Thermador Freedom, Liebherr, Miele, Gaggenau.


 o
RE: High-End Refrigerators?

jsecunda, your last sentence doesn't make sense.

jsecunda, i think your original questions in your first post have been answered, by rococogurl, antss, wa8b, mcmann and myself.


 o
RE: High-End Refrigerators?

some of the newer units also have filters to deal with the ethylene gas that causes problems with some fruits and veggies.


 o
RE: High-End Refrigerators?

jsecunda's last sentence meant that: if you buy a separate refrigerator and a separate freezer (as suggested by one person here), the separate fridge would still be using its single coil to run the freezer and refrigerator. Thus, the refrigerator contents would still dry out, as noted above. This obviates the 'fresher longer' advantage in buying separate units. Unless, of course, there are such things as refrigerators with no freezers, and whose coils don't also act as dehumidifiers. If there are such tnings as refrigerator-only units-well, that's why I'm on this list-to learn.

jsecunda thanks you all for the information. I apologize if you think I was "pumping" the list for additional/redundant information. That wasn't my intention. End of thread.


 o
RE: High-End Refrigerators?

separate refrigerator = fridge only, with no freezer at all, in this box / device / product. Therefore, the cooling circuit only refrigerates and does not work with a freezer.
- Hope this answers it.

RE: High-End Refrigerators?

Thank you for asking this question! I have been struggling with a fridge decision for weeks. I am going to refocus my thinking with a 2-compressor theme now.

As to the OP's question, I think it will be pretty hard to find a refridgerator-only free-standing high-end. From what I've seen most high-end residential fridge-only products are built-in. There are, I'm sure, commercial free-standing refrigerator-only units meant for restaurants, etc.

The built-in refrigeration options are beautiful and $$$$. I have been having a secret affair with Thermador Freedom columns, and it turns out my husband also is in love. We are limited to a 42" width, tho, and we are not happy with the $$'s and volume we'd get in a set-up with 18" freezer and 24" fridge columns. Back to the drawing board.


 o
RE: High-End Refrigerators?

Thanks, Karen. That was sort of my point. I haven't been able to find a residential, free-standing, refrigerator-only box/device/ product either. So the fact that a theoretical "fridge-only" unit may exist somewhere in restaurant land is not helpful in making a home kitchen decision. Knowing that the dual compressor option that Sub-Zeros and Leibherrs feature offers me a rationale for spending the extra money.


 o
RE: High-End Refrigerators?

"So the fact that a theoretical "fridge-only" unit may exist somewhere in restaurant land is not helpful in making a home kitchen decision."\

this isn't your only choice if you don't want built in.

Search here for Fridgedaire "twins" and look at Sears' Kenmore Pro or whatever it's called now. They have free standing all fridge all freezer units with fake built-in look trim kits. Not bad looking and fairly reasonable. They are marketed under the Electrolux label too.

Keep in mind that it's basically a bottom of the barrel frigedaire modeldressed up for the ball and there have been complaints about reliability, but they look good and at @ 1000-1500 bucks you can get a few before you reach built in price land.


 o
RE: High-End Refrigerators?

I believe these from Liebherr qualify. But high end and free standing are much more of a Euro concept than American. Here most go for fitted cabinets and built in appliances.

Here is a link that might be useful: Freestanding


 o
RE: High-End Refrigerators?

Indeed there are all-fridge units made in middle America for middle America. As antss said.

Their cooling systems do only one of the following:
cool and keep cool, or
freeze and keep frozen.

This means they are optimized to do that one thing well.

I've seen them at 700 dollars. The best price around for any reasonably sized fridge.


 o
RE: High-End Refrigerators?

First off, thanks for explaining why my post-EnergyStar fridge is worse than my "old" fridge on keeping greens anywhere but the crisper or when wrapped with damp paper towels.

[I]f you buy a separate refrigerator and a separate freezer (as suggested by one person here), the separate fridge would still be using its single coil to run the freezer and refrigerator. Thus, the refrigerator contents would still dry out

I think there is still some confusion here. The problem with humidity comes from the moisture in the air being "frozen out" by the low temperature causing either condensation and freezing (or snow?) because of the lower moisture capacity of colder air. When that dry air is pushed into the fridge compartment, it is dry. Cooling the refrigerator with its own set of coils is an advantage as it does not significantly any more moisture than required by the 33-ish temperature, compared to the 0-ish of the freezer.

Or maybe it's me

Or, if I mis-read -- many of the Samsung combo units solve this with a single compressor and two cooling circuits.

Samsung Offers A Cool Twist on Refrigeration
14 May 2006

Imagine converting your fridge from a place where food goes to spoil to a place where food is preserved. Imagine a new refrigeration system that would allow you to customize your fridge compartments, creating optimal temperatures for different food items. Believing nothing should be left purely to the imagination, Samsung Electronics Canada has launched a new line of refrigeration products - the Twin Cooling System and Quatro - promising to put traditional fridge/freezer technology on ice.

The majority of refrigerators in Canadian homes are equipped with one cooling system meaning that air is exchanged between the freezer and fridge compartments. A small fan moves the cold air from your freezer into your refrigerator. While this system has been the standard, the engineers at Samsung strived to create a new cooling system that would provide superior food preservation and prevent odours from being exchanged between the fridge and freezer.

"Frozen air is very dry, like Edmonton in January," explains Politeski. "Most refrigerators have a humidity level of approximately nine per cent - this is very dry air. This dry cold air is a problem because moisture and coolness are the key elements for long lasting freshness. Your refrigerator has the coolness taken care of, but the moisture is missing and it's causing your lettuce to wilt and your tomatoes to shrivel."

To overcome the moisture challenge, Samsung has developed the Twin Cooling System where two independent evaporators (the cool comes from evaporators) driven by a single compressor supply the optimum level of cooling air to both the refrigeration compartment and the freezer. Standard refrigerators use a single-evaporator system that uses dehumidified air from the freezer compartment to cool the refrigeration compartment, allowing food to lose moisture faster.

By separating the cooling systems, Samsung refrigerators produce only cool moist air for the refrigerator section. This air has a moisture level of approximately 42 per cent - almost five times the humidity levels achieved in single cooling (one evaporator) refrigerators. By keeping the moisture level high, veggies stay crisp and fresh longer.

With the Twin Cooling system, cold air does not travel between compartments, so food retains its humidity, stays fresher longer and odours do not mix between compartments. The Twin Cooling line is available in two model platforms; bottom mount freezer and side-by-side.

Is There A Poor Man's Solution?

For a temporary solution if you have a lower-end refrigerator, could one keep an uncovered container of water in the refrigerator compartment, to increase the humidity there? Or does that humidity travel back to the freezer and cause problems there?


 o
RE: High-End Refrigerators?

It won't work because they circulate air TOO much, and they make it pass over frozen coils (which are not visible or accessible). Then, to get rid of the ice (icy) condensation, they heat it up, and make that drip water evaporate and go into the air of the surrounding room. That is the plan. In American made fridges.


 o
RE: High-End Refrigerators?

This is great information. Thank You Wa8b. I was unsure whether to spend money on a high end ref if it would be worth it but now I know to look for the 2 separate compressors. I had a sub zero before and have moved and was trying to decide if another ref would work just as well. Now at least I know what to look for.


 o
RE: High-End Refrigerators?

I researched the Frigidaire and Kenmore twins, fridge and freezer in two units installed side by side with trim to look like a built-in. I decided against this route due to reports of high level of noise from the compressors and lack of Energy Star ratings. Perhaps things have changed on these, my research was about a year ago.


 o
RE: High-End Refrigerators?

In addition to the humidity issue which has been very well addresed so far, it is also important to note that a higher quality fridge (SZ, Gaggenau, etc.) will keep the fridge and/or freezer at a constant temperature, and a TRUE temperature. That also helps to keep food fresher for a longer period of time.

Help with Appliance Purchases..PLEASE

Hello; I building a new house in California. I need all new kitchen appliances but their are so many choices my head is swimming. I am looking for 42" built-in frig; 48 stove; dishwasher, MW etc. I love glass doors on the frig.

I can afford SZ and Wolf but my contractor says they're not worth the premium. I would like something stylish with the reliability of a Honda.

Suggestions would be greatly appreciated.

THANK YOU VERY MUCH IN ADVANCE.


 o
RE: High-End Refrigerators?

There certainly are appliances that offer superior performance or appearance that many believe can justify a premium cost. A lot depends on just what is important to you as to which brand in a specific appliance is "the best" in some price range. I believe most here would say that you should pick the make, for each appliance, that is "best" for you, rather than trying for matchy-matchy on them all.

Search around here a bit, then, once you've narrowed it down a bit, you might want to ask some specific questions.

I would not listen to your contractor. This is where you need an architect, desinger or possibly a real estate agent to advise you. Because the refrigerator has such as big frontage in the kitchen, it is a big design element. The contractor is not making money based on their design sense.

I am not sure what your budget is but you do need to put in expected level of appliance for the house at that price point if you need to sell not too long from now.

Because the lesser expensive friges are all doing SS fronts now, the cabinet covered fronts stand out for its price point as well as the look. I don't think the brand is not nearly as important as the fact that they are built-in or integrated. Subzero still carry clout, however. You also need to look at the local housing market. I would tour a few homes that are in your price point.

Unfortunately, we do have to build some-what for resale.
