Black Small Quiet Accommodation Mini Bar Fridge 46 Litre Reliable Schmick Brand

Energy consumption is probably one of the most important factors in buying a glass door fridge, due to the nature of being a ‘glass door’ it is not uncommon for 2 x fridges that ‘look’ the same to have up to 4 x times the difference in power consumption.

One area that confuses here is that glass door drinks fridges are classified as ‘commercial’, meaning they do not require energy consumption labels. This makes it hard for the consumer to try to compare as there is no ‘set’ way to advertise power consumption unless the units have had MEPS testing done and results then show online. MEPS is usually only done when food needs to be stored in the fridges, it’s an expensive test but to advertise units as OK for food storage it has to be done. If units are only being advertised and sold as ‘drinks fridges’ then MEPS is not required, meaning that anyone can import a fridge and sell as a drinks fridge with NO requirement to abide by any energy consumption standard. This means there are so many units that draw plenty of energy and no way for the average punter to know.

The parts that draw the most power are mainly the compressor, lighting and fans, so with these 3 things you can focus on consumption based on what is used. Generally brand name parts are better rated than cheaper no name fans and compressors. Lighting other than LED will draw more, LED is long lasting and reliable and is commonly used now in a lot of fridges.

Although parts play a major factor, the function and ‘refrigeration balance’ of the unit also dictates a lot in how much energy is used. A fridge that is ‘balanced’ well will chill quicker and hence draw less energy, a fridge poorly designed will need to run more to get to temperature. You will find a lot of cheaper units can’t handle ‘hotter ambient’ temperatures, they struggle and run for much longer to get to desired temperature, hence can use extraordinary amounts of energy. Some of the tests we have done on other units in market in our test room were frightening!

After doing this since 1996, I have learnt so much and I can honestly say that 90% of factories in China really have no idea what they are doing in regard to ‘balancing fridge systems’ with correct compressor and correct sized parts to suit the units to run efficiently.

So in short there really is a difference between fridges that look the same. You need units proven to chill in higher temperatures at a good rate, saving working time on parts and energy consumption and $$$.

Definitely our biggest complaint over the years is noise levels. The recent new trend of having glass door refrigeration is popular but a lot of people really do not know what they are buying, as it was never really an available product for home applications 10 years ago.

Now that it is very popular you have to be wary of the location you are placing it and what noise levels it does run at. Everyone’s perception of noise is different and so it makes it difficult to explain noise. A common metric is the ‘Decibel Rating’ known as dB, this gives a figure that can be compared to other appliances to help get an idea. The scale is very odd to understand as about 25dB is actually nearly silent, 36>43dB is a household fridge, yet only 55dB is like a microwave. See the chart we compiled using basic household items in 5 x different homes and taking the medium.

As you can see a hair dryer is 80dB, now that is loud, very loud, yet room noise is only 30dB, this is a room with nothing on or going, basically nothing.

Domestic fridges can range from 36 to 43 depending on brand and compressor and age, an older fridge often runs with a noise that you just get used to, but most are no more than 43dB.

We have a lot of units that we specially fit 12V quiet (silent) fans to, these are from an Austrian company and run silent at 20-29dB, really making noise levels very low. We also have more commercial type quiet fans that run at 39dB compared to standard commercial fridge fans at 55dB. As you can see from the chart the difference between 39dB and 55dB is huge.

There are many variables that can alter the noise level of your fridge, we have talked about fans but the main compressor can also be the part that causes the grief. Depending on compressor type or size they can still run from 39dB>55dB, so even with quiet fans you may still have times of higher levels of noise during run times. Other variables are things like the room the unit is located in, a ‘hard’ room with hard wood floors will reverberate noise much more than a soft cushiony type carpeted room. The cavity where the fridge sits can also cause more noise enhancement so little things like ‘lining’ the rear wall with foam or sitting the fridge on a rubber mat can also make a difference. Triple glazed and solid door units also keep inner noise contained and units with plenty of space ‘in front’ of them can also be slightly less noisy - this allows the noise to dissipate into the environment.

Alfresco fridges used outdoors work extremely hard and build up a lot of heat during normal cycling up/down in hotter ambient temperatures. What this means is that bigger fans are needed to expel the extra heat in a timely manner so the unit can run efficient while chilling, so in general alfresco units will be louder because of this reason. We can alter fan system in these too quieter, but quieter means slower RPM (Revs Per Minute) and less air movement making it take longer to get units down to temperature, hence more power consumption. So we can make units quieter and they are still ok but the trade-off is more energy consumption.

This same principle applies to commercial units which often have many door openings and high usage so quicker chilling function is better for units in harsh applications.

So anything is possible and we do plenty in this area to make units as quiet as possible and to offer options, there are just all these things to consider before you make such a high $$$ purchase.
