The reason why the refrigeration compressor uses 200-grade enamelled aluminum wire is not because its own working environment is 200 degrees, but because of the performance of the refrigerant! High-efficiency products based on aluminum wire technology have recently appeared in the refrigerator compressor industry
1. Ambient temperature: Refrigeration compressor (whether it is an air conditioner or a refrigerator), its working environment temperature is normally about 90~120 degrees, and some models may reach 130~150 under certain circumstances (such as overheating). load operation), even if there is an extreme situation, the working temperature of the compressor will not exceed 180 degrees. Therefore, for the enameled wire used in the compressor, the temperature resistance of 180 is actually enough!
2. Refrigerant resistance: Refrigerant resistance is one of the most important properties of enamelled aluminum wire for compressors. Ordinary enameled wires, such as 130 or 155 polyester polyurethane products, will be in the working state of the compressor when it is hot and cold. Under the hood, foaming occurs (that is, the enameled wire is swelled by the refrigerant, and the paint film becomes a sponge-like porous body), thereby losing insulation and short-circuiting, resulting in the compressor being effective. At present, among the conventional enameled wires, the best refrigerant resistance is the 200-grade enameled wire of polyesterimide compound polyamideimide;
Therefore, the refrigeration compressor will use 200-grade enameled aluminum wire.
