Abstract
A scroll compressor includes a liquid injection system. The liquid injection system receives liquid refrigerant from the refrigeration system at a point between the condenser and the evaporator. This liquid refrigerant is then injected into at least one enclosed space defined by the scrolls of the scroll compressor. The liquid injection system includes a valve which selectively controls the flow of liquid refrigerant to the enclosed space. The valve is responsive to the discharge pressure of the compressor.
