Understand the Cooling Effect of a Fridge with 35 kW Capacity | Easy Explanation

[TSN79]

A cooling system for a fridge at a store has a cooling effect of 35 kW. I'm having a bit of trouble understanding what this actually tells me, iow what it means. Could someone explain it in some easy manner...?

When someone says that there is a cooling need for 35kW, I don't really get it. If someone said that this room needs to be cooled from 30C to 20C, I understand it a bit more, but to express these 10C of needed cooling in terms of kiloWatts is more than I understand...

The refrigerator is capable of sucking in 35 kJ of heat per second.

I can explain the cooling effect of a fridge with a 35 kW capacity in a simple manner.

Firstly, kW or kilowatts is a unit of power, which measures the rate at which energy is transferred or converted. In this case, the 35 kW capacity of the fridge tells us how much energy it can transfer or convert into cooling per unit of time.

To understand this better, imagine you have a fridge with a 35 kW capacity and another one with a 50 kW capacity. Both fridges are set to the same temperature and have the same amount of food inside. The fridge with a 50 kW capacity will cool down the food faster because it can transfer more energy in the same amount of time compared to the fridge with a 35 kW capacity.

So, when we say that a fridge has a cooling effect of 35 kW, it means that it can transfer or convert 35 kilowatts of energy into cooling per unit of time. This is an important measure because it tells us how powerful the fridge is and how quickly it can cool down its contents.

In terms of the example you mentioned, if a room needs to be cooled from 30C to 20C, we can calculate the cooling effect needed in terms of kilowatts. This would depend on the size of the room, the insulation, and other factors. But let's say we need a cooling effect of 10 kW to cool the room down. This means that we need a fridge with a capacity of at least 10 kW to effectively cool the room.

Overall, the cooling effect of a fridge with a 35 kW capacity means that it is a powerful fridge that can quickly cool down its contents. I hope this explanation helps you understand the concept better.
