TWO-STEP CAPACITY MODULATION OF A SINGLE CYLINDER COMPRESSOR

摘要

Energy efficiency will become an increasing concern in the next decade, and disproportionately so for small, single cylinder compressors because of their widespread use in consumer products. An effective way to dramatically improve system efficiency is through the use of capacity modulation. Through the use of a special mechanism, a single-cylinder reciprocating compressor can provide two-step capacity modulation for little added cost. Many of the benefits of fully-variable capacity can be achieved with two-step modulation: improved system efficiency, decreased cycling and improved temperature control. This can be done in a cost-effective manner and can be easily adapted to existing appliances.
