Follow the Cold King agent to take a look:

1. The refrigerator can lower the temperature of the goods to the low temperature limit of the refrigerator.

The function of a refrigerated truck compartment is to keep warm, while the function of a refrigerator is to ensure that the temperature of the goods inside the compartment remains constant and cannot be lowered.

For example, some customers who pull meat directly put the cut meat of slaughtered animals into boxes. This is the reason why the refrigerator temperature cannot be reached. A refrigerator can easily lower the temperature of the air, but it is difficult to lower the temperature of goods because the specific heat value of goods is nearly 1000 times that of air.

2. Low temperature items are difficult to hit, while high temperature items are easy to cool down

The temperature of ice cream is controlled at -18 ℃, which makes it easy to beat. On the contrary, the temperature of Mengniu's probiotic milk, fruits, vegetables, and yeast is difficult to break. When the temperature of the container drops, not all of the goods' temperatures also decrease. The temperature of Mengniu probiotic milk can only be controlled at around -4 ℃ inside the cabinet and around 4 ℃ inside the probiotic cup. this is it.

3. The less goods there are, the higher the temperature?

The fewer products there are, the greater the air volume in the box, which is also one of the reasons why the temperature of Mengniu probiotic milk is difficult to break.

1) The air volume in half of the car is too high.

2) Fermentation of goods generates heat.

4. Can a high-quality refrigerator blow out the fog inside the box?

The main reason for the heavy fog is that there is too much water in the box or the refrigerator has poor drainage, which is not a good phenomenon. You can judge by looking at the thermometer. It can also be determined by the water holes outside the refrigerator. If there is continuous water outflow during the heating process, this is normal. Otherwise, the self flow port will be blocked.
