Test results of a low output wet screw refrigerant compressor with a new teeth form at high temperature conditions
Annotation
The results of testing are presented for a low output oil-flooded screw compressor with a new profile of teeth that works on R134 as a conditioner and a heat pump. Experimental dependences of volume and energy coefficients of the compressor, refrigerating and heating factors are given as functions of external degree of pressure rise.
