Abstract

A refrigeration system has a compressor which incorporates fluid injection into one or more of the fluid pockets. A source of fluid for injection into the pockets is attached directly to the shell of the compressor to eliminate the need for having fluid piping between the source of fluid and the compressor. The source of fluid can be a flash tank which increases the capacity and efficiency of the system or the source of fluid can be a heat exchanger which also increases the capability and efficiency of the system.

Description

[0001] The present invention is a divisional application whose Chinese patent application number is 02142844.1, the title of the invention is "Scroll Compressor with Steam Injection", and the filing date is September 18, 2002. technical field [0002] The present invention relates to machines of the scroll type. More specifically, the present invention relates to a hermetic scroll compressor incorporating a vapor injection system utilizing a heat exchanger or flash tank mounted directly on The casing of the scroll compressor. Background technique [0003] Refrigeration and air conditioning systems typically include: a compressor, condenser, expansion valve or equivalent, and an evaporator. These components are sequentially connected in a continuous flow channel. A working fluid or refrigerant flows through the system and alternates between a liquid phase and a vapor or gas phase. [0004] Various types of compressors have been used in refrigeration and air conditioning sy...
