Title: COOLING CYLINDER CIRCULATING REFRIGERATION SYSTEM
Abstract:
A cooling cylinder circulating refrigeration system composed of a rotor cooling cylinder compressor and a machine unit, the low temperature cooling cylinder wall being able to implement low temperature cooling cylinder suction and cooling cylinder heat release compression, an insulating layer being arranged on the outside of a working chamber and an air suction tube to prevent cold from leaking into a high temperature high pressure chamber and forming cold damage. Air chamber insulating rings (24, 28) of a main and an auxiliary bearing (21, 27) positioned on the wall of an air chamber and a rolling piston (26) surface insulating layer (36) and sliding piece surface are all made of a lipophilic wear-resistant insulating material. An outdoor unit is provided with a cooling base plate (38) and an immersion supercooling spiral coil (39), using an internal water return to enhance cooling. The present cooling cylinder circulating refrigeration system increases the cold and reduces the compressor power.
