How to look at the refrigerator insulation layer, and what is the temperature of the refrigerator pr

Most of them look at it from the top, and it's fine. The thickness is measured with a ruler, and the thickness of the inner tank and shell is omitted.

What brand of refrigerator are you purchasing? The quality of polyurethane insulation is directly related to power consumption and service life. I am a polyurethane raw material, and the quality of polyurethane materials is generally not easy for outsiders to see. It is recommended that you buy a big brand, at the same price and at the same price.

Pinch it with your hands and see how thick it is

It's not very good-looking, and it can only be analyzed from the thickness.

The insulation layer of the refrigerator is not as thick as possible. The thicker the insulation layer of ordinary materials, the better the insulation effect, and the disadvantage is that the effective volume of the refrigerator will be reduced. However, with the continuous innovation of the technical team of various merchants, there are already some refrigerators on the market that can reduce the thickness of the insulation layer while improving the thermal insulation effect.

Speaking of thickness, it is natural to talk about the material of the insulation layer itself. Compared with traditional refrigerators, the insulation layer of most refrigerators is made of high-tech materials, and the insulation effect is needless to say. However, at present, some domestic brands are still using the old foaming materials, and you may wish to pay attention to the foaming agent materials of the refrigerator when purchasing refrigerators, so as to avoid spending a lot of money on inferior materials.

The insulation layer of the refrigerator is directly related to the quality of the refrigerator freezing and preservation. Therefore, when purchasing a refrigerator, you must pay attention to the material and thickness of the refrigerator insulation layer.

There will be a thermostat in the refrigerator, and the brightness can be adjusted through the gear of the refrigerator thermostat to adjust the refrigerator temperature. However, when adjusting the temperature level, if the gear adjustment is wrong, the normal work efficiency and freshness of the refrigerator will be affected.

Usually the freshness temperature setting:

1. The temperature distribution of the refrigerator is uneven.

The temperature in the refrigerator is a temperature ladder from top to bottom, the upper temperature is lower, about 3 degrees, the lower end of the fruit and vegetable box is higher, about 6-10 degrees, according to the national standard, the temperature of the refrigerator refrigerator should be between 3-10 degrees.

2. A simple measurement method for the temperature of the refrigerator.

Place the design thermometer in a cup filled with water, and then place the cup in the cold room, located on the back wall of the middle floor. The measurement time is at least 2 hours, and then the temperature of the previous layer and the next layer is measured, and the average value is taken. In "4" gear, the temperature of the refrigerator is generally around 7 degrees.

3. Adjust the refrigerator stall.

Adjust in the middle of 3-4 in the summer and 1-2 or 2 in the winter, a principle to keep the temperature of the refrigerator room at 5-10 degrees Celsius. Fresh fish and meat should be sealed in plastic bags and stored in the freezer. Vegetables and fruits should be wiped dry with moisture on the outer surface, put them in the refrigerator and under them, and store them at a temperature above zero.

Generally, after opening the refrigerator, there will be an indicator light on the top or side of the refrigerator, and there will be a scale next to the indicator light, which is the temperature of the refrigerator socks in the fresh-keeping room. Under normal circumstances, the temperature can be set at 4-5 degrees, which is conducive to the preservation of food and can be kept fresh for 3-5 days.

A refrigerator is a kind of refrigeration equipment that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. Inside the box there is a compressor, an ice machine for freezing cabinets or boxes, and a storage box with a refrigeration device.

Refrigerator. Insulation.

The main function is to insulate heat. When the refrigerator works, the "heat" is moved from the inside of the refrigerator to the outside, because the temperature inside the refrigerator is low, and the heat will re-enter the refrigerator from the outside, resulting in the refrigerator compressor.

Start to move the heat out of the refrigerator again. Therefore, the meaning of the refrigerator insulation layer is to isolate the heat and prevent the heat from re-entering the refrigerator. A good insulation layer can reduce the number of times the refrigerator is started, so as to achieve the goal of saving electricity.

What brand of refrigerator are you purchasing? The quality of polyurethane insulation is directly related to power consumption and service life. I am a seller of polyurethane raw materials, and the quality of polyurethane materials is generally not easy for outsiders to see.

It is recommended that you buy a big brand, at the same price and at the same price.
