Embodiment Construction
[0071] The present invention will be described in further detail below in conjunction with the drawings and examples.
[0072] combine figure 1 and image 3 Specifically clarify the thermodynamic working process of the mixed working medium throttling refrigerant proposed by the present invention:
[0073] The mixed working medium throttling refrigerant of the present invention enters the compressor CP from the state L1 and is compressed to the state G01; then enters the cooler AC to cool to the state G0; enters the regenerative heat exchanger HX and is further cooled to G1; then passes through The throttling element JT becomes L3 after throttling; enters the evaporator EV, extracts cooling capacity and becomes L2; b then enters the recuperation heat exchanger HX for reheating, returns to the state L1, and completes a thermodynamic cycle.
[0074] for figure 2 The thermodynamic cycle shown has the same basic working process, except that one stage of vapor-liquid separatio...
