Abstract

A scroll compressor incorporates a vapor injection system where only one vapor injection port is utilized. The single vapor injection port injects refrigerant vapor into two of the initially formed enclosed spaces. The scrolls of the scroll compressor are designed with asymmetric wraps where the non-orbiting scroll wrap extends angularly further than the orbiting scroll wrap.

Description

technical field [0001] The present invention relates to machines of the scroll type. More particularly, the present invention relates to a scroll compressor that includes a vapor injection system utilizing a large port extending through the scroll member. Background technique [0002] 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 flows through the system and alternates between liquid and vapor or gas phases. [0003] Various types of compressors have been used in refrigeration systems including, but not limited to, reciprocating compressors, screw compressors, and rotary compressors. Rotary compressors may include vane compressors and scroll compressors. Scroll compressors are constructed with two scroll members, each having an end plate and a spiral wrap. The helical windings are arranged in...
