Refrigerator inverter refrigerator, "frequency conversion" what does that mean?
More than 250 liters of revenue greaterTo improve the efficiency of the refrigeration system there are three kinds of methods: the first is using energy saving components and energy-saving technologies, such as high efficiency compressor, high efficiency heat insulation technology, advanced technology and other second kinds of foaming; is to improve product design and matching, the structure parameters and system parameters optimization design method to determine the product the third category is; energy saving operation and use. It includes two aspects: on the one hand, the refrigerator has a higher efficiency in a wide range of working conditions; on the other hand, the refrigerator output compatible with the load, which is applicable to any such knowledge, equipment and energy products.
The main features are: the inverter refrigerator refrigeration capacity can be adjusted, the cooling capacity of the refrigerator can be well matched with the load of the refrigerator, avoid unnecessary energy consumption; when the refrigerator required cooling capacity is small, the compressor can be running at a low speed, reduce the number of starts.Compared with the conventional refrigerator, has the advantage of energy saving in two aspects, one is less frequent refrigerator loss caused by shutdown stop / start; two is to reduce the energy loss caused by the refrigerator shutdown system of high and low voltage balance, at boot time and must be to establish the high and low pressure caused by the loss.
Inverter refrigerator with inverter compressor, and increase the frequency controller in the refrigerator control system, refrigeration compressor speed can be changed by changing the refrigerator. Because of the high cost of the inverter compressor and inverter, the inverter refrigerator price is higher, is now generally used in high-end refrigerator products.Obvious advantages of frequency conversion
The control is more accurate and stable. The frequency conversion compressor usually adopts brushless DC motor drive, which reduces the excitation losses caused by the conventional AC induction motorBut the concern is that the frequency control system will bring certain electromagnetic compatibility and electromagnetic interference problems. At the same time, the refrigerator compressor for reciprocating piston compressor, the working principle and structure characteristics of the compressor determines the frequency range is relatively narrow, leading to the dominant parties as inverter refrigerator inverter air conditioner so obvious.
