一种空调压缩机低温预热的方法
By dividing the preheating level in the air conditioning compressor and adopting a zoned heating method with differentiated temperature rise rate and target temperature, the problem of non-uniform thermal stress caused by differences in material thermophysical properties and structural stiffness in low-temperature environments is solved, thereby improving start-up reliability and service life.

AI Technical Summary
When an air conditioner compressor starts up in a low-temperature environment, the non-uniform thermal stress caused by differences in the thermophysical properties of materials and structural stiffness affects the reliability of startup and its service life.
By acquiring the spatial location and material deformation of the internal components of the compressor, the preheating level is divided, and a zoned heating method with differentiated temperature rise rate and target temperature is adopted. Combined with real-time temperature feedback and dynamic adjustment, the heating parameters are dynamically adjusted to avoid local overheating or undercooling.
It effectively overcomes the problem of non-uniform thermal stress caused by differences in material thermophysical properties and structural stiffness in low-temperature environments, and improves the low-temperature start-up reliability and service life of the compressor.
