Now many refrigerators have three layers, of which the freezer is generally located in the bottom layer, this kind of refrigerator can save more food, in home life is very common, but due to some fault problems, three layer refrigerator often appear bad refrigeration phenomenon, today we are introduced to the three layer refrigerator most ground layer is not cold how? Take a look at it!
1, if the refrigerator freezer is not cold, to see if the compressor of the refrigerator is not a problem, the compressor of the inner high pressure output buffer tube broken, or fixed this tube screws loose, it will cause the high pressure tube not exhaust, low pressure tube not suction, although the compressor of the refrigerator is running, but the refrigerator freezer is not cooling.
2, if the compressor of the refrigerator does not stop day and night, the freezer may cause the refrigerant limit refrigeration temperature. And most of this phenomenon occurs in the air-cooled freezer refrigerator. The reason is that the freezer evaporator frother is bad, produced ice blockage.
3, sometimes the compressor of the refrigerator is running, but the refrigerator freezer is not cooling. It is possible to make the refrigerator refrigeration system leakage, refrigerant all leak out, the system no refrigerant evaporation heat absorption, resulting in the refrigerator temperature does not drop, the freezer does not cool.
4, refrigerator in the ambient temperature is too high, it will pipeline slight blockage, causing condenser condensation is not sufficient, refrigerant can not be completely liquefied, so that the refrigerant into the evaporator, it is possible to completely evaporate in the freezer, into gas, and to the freezer, there is no liquid refrigerant state, thus can not refrigeration.
Refrigerator does not cool the solution
First of all, we can check whether it is a problem of power supply, you can open the box door, observe whether the box lighting is lit, or test the power line with an electric pen to see if there are traces of broken wires, such as being bitten by rats. When the evaporator frost can not be melted off after blocking the air duct mouth, the cold can not go out, resulting in the refrigerator is not cooling. At this time need to check the frosting system, may be the frost timer has a fault, or heating tube has been burned off.
Refrigerator refrigeration system working principle introduction
1, double door direct cooling refrigerator refrigeration system is the use of freezer and refrigerator room in the evaporator directly absorb the heat of the air inside the refrigerator, to achieve the refrigerator refrigeration.
2, double door refrigerator refrigeration system is relying on the refrigerator fan forced air blowing a way to make the refrigerator in the refrigerator in the cold air circulation, and finally achieve the effect of refrigerator refrigeration, this intercooled refrigerator in the process of operation will not frost, so is called frost-free refrigerator. In its freezer and freezer room each has a thermostat, their temperature are through their respective thermostats to adjust.
