In daily life, the emergence of refrigerators is still very important. In order to avoid the phenomenon of food deterioration, some people will put ingredients into the refrigerator to protect them, so that they can not only achieve the effect of refrigeration, but also make the quality of ingredients become better and better. According to the working principle of refrigerators, it is divided into the following three kinds.
1. For the expansibility of the refrigerator at the same time, the refrigeration compressor works for the intelligent control system. The system software of the refrigerator is made of the principle of evaporation and heat absorption of the refrigerant less than the melting point in the air conditioning evaporator. If it is the refrigerator of absorption heat pump, this kind of refrigerator can use the electric heating as the driving force, the mixture of sodium hydroxide hydrogen solution according to the form of continuous absorption of heat spread, with which to achieve the effect of refrigeration, but this method of refrigeration efficiency becomes low, so the temperature reduction speed is relatively slow. Semiconductor material refrigerator is a refrigerator with a very wide range of application at the present stage. According to the connected DC power supply in the connection points, the corresponding Peltier effect is completed.
2. The most important refrigeration method of refrigerator is the principle of a heat pump unit, the use of mechanical kinetic energy in the case of heat insulation in the refrigerator, the heat energy is removed from the refrigerator, similar to the refrigeration of central air conditioning. And in daily life, there is the phenomenon of refrigerator refrigeration, in which the main reason is that the temperature in the refrigerator is too high, resulting in the decline of the refrigeration system software, in other words, if there is no refrigerant, it will cause the phenomenon of refrigerator refrigeration, the most intuitive solution is to explore the maintenance workers to re-enter the refrigerant.
3. If there is a problem with the temperature controller, it is also due to the inability to normally control the temperature, so the refrigerator in this case is no way to operate normally. If this happens, it is proposed to replace the temperature controller at the first time. If these problems are dealt with have no method of normal refrigeration, the worst situation is likely to be refrigeration compressor damage, in this case only for refrigeration compressor maintenance, but the need to hire professional on-site service disassembly.
