Have you ever noticed that if you stand close to the walls of a freezer, you might feel warmth? This is because the sides of freezers can be a couple of degrees warmer than the room temperature. While this is normal, freezers might get too heated at times, which is a cause for concern.
Commercial refrigeration in India plays a critical role in the Indian food industry. The heating up of the cooling devices can put a dent in the revenues of restaurants and grocery stores as they lead to food wastage.
How does a freezer keep its temperature cold?
The cooling mechanism of freezers is rather simple. Its compartment is lined with a cooling pipe, which is connected to a pump that sucks in vapour. This essentially turns liquid into vapour. The evaporation generates heat that is transmitted out of the freezer.
Now, the pump turns the vapour into liquid again by taking the vapour from the cooling pipe and sending it into another pipe. This again, produces heat, which can be felt on the walls of the refrigerator.
While all of this may seem like a pretty straightforward process, the heat produced can quickly increase in intensity. This can pose a major challenge for commercial refrigeration in India. So let’s explore why the freezers get heated (or overheated).
10 reasons your commercial refrigerator is getting heated (and how to prevent them)
It is very easy to confuse the normal warm temperature of your freezer with overheating. One simple diagnosis that you can run is to check how fast the food is cooling. If it doesn’t cool as fast as it should, one of the below could be the reason.
Condenser coils need to be cleaned
The heating up of commercial refrigerators in India, or anywhere else, could be an indication that their condenser coils need a bit of cleaning. Freezers use a gas known as cool refrigerant to supply cold air in your freezer. The free flow of cold air could be impacted if your condenser coils are dirty.
We suggest you clean them at least once every 3 months to remove the buildup of dust and grease.
Your doors aren’t shutting properly
The doors of commercial refrigerators in India aren’t just doors. They actually play an important role. The rubber gasket on a refrigerator’s door acts as a seal to keep cold air inside the freezer.
It is important to keep an eye out for wearing and tearing of the rubber seal of the freezer door. It is important to keep checking if the doors are loosened or damaged.
Your freezer thermostat is faulty
For most commercial refrigerators in India, the normal thermostat temperature is 0°C to 4°C while deep freezers range from -15°C to -25°C. Cold drinks need temperatures between 2°C to-4°C. There is a greater risk of the bottle getting damaged if the temperature is less than 2°C. Although you might set the right temperature, a fault could trick your machine into warming up the freezer. Such an oversight could damage the freezer and also spoil all your food.
One simple solution to avoid this issue is to give up the practice of overstocking the freezer which blocks your view of the thermostat.
Break down of freezer’s compressor
A compressor triggers the cooling mechanism by converting the state of refrigerant into a condensed form. This then is sent into condenser pipes to activate the cooling mechanism. If your compressor breaks down, your freezer turns into a simple storage cabinet.
Your freezer indicates that the compressor needs repair or replacement by making loud noises along with unusual heating of the walls.
Not letting your freezer breath
Commercial refrigerators in India are infamous for overstocking huge quantities of food. Although they are for the very same purpose, it is essential to leave some room for air to circulate inside the freezer. By covering up the vents with stocks of items, you block the free flow of cold air that keeps food fresh.
Avoid overstocking food items in your freezer or remove objects blocking the air vents to allow the refrigerator to do its work.
Keep your freezers cool with the right pick
Commercial refrigeration in India is growing at a steady pace owing to the uptick in food-related businesses. They are simply a no-brainer for businesses that want to store large quantities of items. However, freezers often have overheating problems. You can prevent it through timely maintenance and efficient use of the cooling machine.
While market has a number of refrigeration brands, there are only a few handful of companies that produce high-quality freezers. Rockwell, one of the leading refrigeration company, has an entire range of best-selling freezers built on innovative technology that retains cooling for over 10 hours even without power.
