Experimental Study on Expander for R32 Refrigeration System
摘要
Based on the self-built experimental platform, the expander used in R32 refrigeration system is studied experimentally. The operating resistance moment of the expander, the minimum pressure difference required for self-flooding and the range of self-flooding dryness of the expander are obtained through experimental research. The experimental results show that the average resistance moment of the expander is 0.207 Nm, the minimum pressure difference of self-drive is 0.4 MPa, and the inlet refrigerant of the expander is X > 0.04, the expander can realize self-drive.
