It doesn't effect at all. The purpose of freezer design below is the frequent of use and your most convenient use from certain manufacturing sturdy. The new design drawer freezer do give better efficiency and save some cold lost.

The front door fridge is not efficient and lost a lot of cold air when door open. The cold air will flow out as door front door open. Which cold air is heavier. As the bottom drawer type, the air can't flow out much more. Cause cold air don't rise.

The most efficiency fridge is modify those freezer as fridge. Those top open door freezer where mostly use for restaurant and wet market. Put some thermostats and set to fridge temperature. It save your bill a lot.

Panasonic is coming up with a top freezer soon by this year definitely. Wait if you are not in hurry.

The cold air lost mainly is cause by the door type. Front door type open will have more cold air lost. Due to cold air heavier and intend to flow out downward. Doesn't matter the freezer ontop or below. You can stand beside the fridge and try open the door. You can see the cold air cloud rush out downward. Either you open the freezer or fridge side, it still lost amount of cold air. Very much depend on how fast you close back the door and don't let the temperature rise further.

The design of freezer drawer type at bottom have 2 advantage from my oppinion. It reduce your squarting and poking into the freezer to look for something. It is difficult for older people. Squarting and looking forward is difficult. While bending and look downward is much more eassier if a drawer type. Another advantage is the minimum cold air lost for the drawer type.

But I find out also, the drawer type of freezer have lesser space than the front door type. The drawer occupy some space.

Again as I said, top door open freezer is the most efficeint. As cold air don't rise.

Side by side front door open is the waste space from my opinion. The center divider occupy a lot of space. And cause the design of the fridge to be wider. But recently I found out a brand name Beko fridge where there is no center divider for side by side door. The fridge have a high rating energy saving compare others same size. Even more energy saving than the smaller size. The fridge have 3 frezzer drawer below and fridge ontop. It is almost perfect fridge for me. But not the price.

I would like to go for the new design where freezer drawer at below and look for most energy saving. If inverter can save, why not. It is difficult for me to break away from the traditional freezer ontop. It look strange freezer at bottom.

I haven't decise on the fridge. I not yet know the kitchen cabinet design, size and space dimension. You need to have nice fridge to blend to your kicthen cabinet.

But my favour is panasonic with around 400liter inverter.

My budget when to new TV already. 

Recently when to senq jalan2. Saw some new sharp fridge range with french door type.And bottom frezzer Quite nice amd reasonable price. I haven't check the detail power consumption and spec.

Go take a look.

Your ice-cream cake can fit easlly into french door type frezzer. Just choose the non drawer type.

Last mth is year end sale for most of the big electrical manufacturing. Many sale and freebie. No go for hunt?
