Description

Technical Field

[0001] The present invention relates to the technical field of compressors, in particular to a vertical fully enclosed screw compressor. Background Art

[0002] A screw compressor is a rotary compressor that compresses and transports gas by rotating a screw-shaped rotor within a cylinder. The screw compressor is the core component of the entire system and is a type of positive displacement compressor. Gas compression is achieved by varying the volume of the teeth of the parallel meshing male and female rotors installed within the housing. The rotor rotates within the housing, which precisely matches it, causing the gas between the rotor teeth to continuously undergo periodic volume changes, pushing it from the suction side to the discharge side, completing the three working processes of suction, compression, and exhaust. Currently, existing semi-hermetic screw compressors have the following problems: The oil flow cannot be adjusted, resulting in excessive oil injection, which increases compressor power and low volumetric efficiency. Excessive oil injection leads to insufficient lubrication of the compressor, which can easily cause the shaft to stick and burn out.

The compressor has the function of automatically regulating the oil flow, thereby preventing excessive oil from entering the compression chamber and reducing power consumption; automatically regulating the self-sensing internal volume ratio to eliminate over-compression and under-compression and improve compression efficiency; and realizing an efficient vertical oil seal to provide the refrigeration system with an exhaust gas with a very low oil content, thereby improving the overall efficiency of the system.

[0004] However, some heat recovery units can only recover about 20% of the heat of the air-conditioning load, and the hot water output is too small.
