容量调节涡旋压缩机系统和方法
摘要：
一种用于调节具有电机的涡旋压缩机的容量的系统和方法，包括确定涡旋压缩机的目标容量，当所述目标容量在第一预定容量范围内时以第一速度操作所述电机，并且当所述目标容量在第二预定容量范围内时以第二速度操作所述电机，根据所述目标容量和所述第一速度或第二速度来确定脉宽调制循环比率，根据所述脉宽调制循环比率来周期性地分开所述压缩机的互相啮合的涡旋构件，从而调节所述涡旋压缩机的容量。
摘要（英）：

A system and method for modulating capacity of a scroll compressor having a motor includes determining a target capacity of the scroll compressor, operating the motor at a first speed when the target capacity is within a first predetermined capacity range and at a second speed when the target capacity is within a second predetermined capacity range, determining a pulse width modulation cyclic ratio based on the target capacity and the first or second speed, and periodically separating intermeshing scroll members of the compressor according to the pulse width modulation cyclic ratio to modulate the capacity of the scroll compressor.
