What is ambient temperature in the room right now where this fridge will be located ?
In my room it's usually 30C during summers, 26-25C in monsoon, 22-24C in winters. My kitchen area has good ventilation but in the afternoon, it receives direct sunlight between 3-5pm from the 3-pane window which raises the temps. Let's keep a difference of 1C, so 29C for now in summer. +_ 1C for variation but not more. My hall is attached to the kitchen and the hall has good airflow. So there is very little heat buildup. Also the ceiling fans in the hall and kitchen throw a lot of air into the kitchen to dissipate the buildup. So I can say for sure that the air is not stagnant in kitchen. The only other time the kitchen area becomes a bit hot is when using the gas stove. We open up the kitchen windows to allow fresh air. This is mostly in morning, so cool air.
You need that space for air circulation otherwise it will consume more. Space is your constraint. At least 6 inches at the back, more is better since you have a shelf and there is no way for the hot air to escape.
1-2 inches on the side. You don't want it to touch anything as then you will get more sound from vibration when the compressor starts up.
I am Giving my total volume, volume used by current fridge and volume of 324L fridge. All dimensions in cms.
Current dimensions- 64+(D)x85(L)x174(H). D-depth, H-height, l-length. I gave depth as 64+ because I still have some room to get the fridge into the front and ensure space at the back for cooling. Refer point below.
Current fridge dimensions - 64(D)x56(L)x142(H). It has a space of 3in at the rear, 4in on the left side, 7in on the right for ventilation. The reason for 3in at the rear is because there is an obstacle which sits parallel to the washing machine prevent me from getting close to the machine while loading, unloading. I am going to get rid of that obstacle which will leave me with more space and have 6in space at the back.
324L dimensions- 67(D)x60(L)x164(H). The depth can be increased after getting rid of that obstacle, so that's covered. Regarding length, I am still left with 17cm(6.69in) gap from the right side, already 4in exists on the left side. So that's covered as well. Now for height, I am left with only 10 cms. Normally this shouldn't be an issue if you have good airflow. But let's say there is zero turbulence or no airflow, warm air from the bottom will rise to the top and dissipate. The shelf atop currently covers only 10% of the top fridge. If I can drag the fridge forward enough so that the shelf doesn't cover it, warm air can rise further up and get dissipated.
But my 470L fridge consumes 30% less than my almost 50 yr old Kelvinator which was half the size.
This should be a given. Technology has made rapid progress so yes. Even from one of the video you posted about power consumption for 253L, his average daily unit came to 0.78, much less than my avg 4 unit/day, assuming same usage scenario.
While comparing the Samsung models old and new, I found that the freezer area, the difference between gross and actual is more on the new than on the old. Not comparing numerically, but from usable area perspective. Don't know if its even a valid comparison, but just a point I observed.
You are asking whether i can clean it ? LG's door gaskets can be peeled off to clean. They have studs that you can push back in. I think the Sammy ones are glued in. Check in the shop.
Yes. But I Missed it yesterday. But from the review video for the same Sammy model, the demo person does show the rubber gasket can be removed. They might have added in their new models. Nevertheless, will be going to my regular shop and will see the same.
Then what is Samsung's latest equivalent compressor ?
Didn't ask. I even wonder sales guy would know what is inverter linear or the difference between digital and linear. If you want, I will ask them.
