EJECTOR REFRIGERATION CYCLE, AND FLOW RATE ADJUSTMENT VALVE

WIPO Patent Application WO/2019/155805

A1

This ejector refrigeration cycle comprises a compressor (11), a condenser (12), an ejector (14), an intake-side depressurisation unit (15), an intake-side evaporator (19), a guiding bypass passage (16), and a variable-throttle mechanism (17). The intake-side depressurisation unit depressurises a refrigerant. The intake-side evaporator causes the refrigerant depressurised by the intake-side depressurisation unit to evaporate and flow out towards the refrigerant intake port side. The bypass passage causes the refrigerant on the inlet side of the intake-side depressurisation unit to bypass the intake-side depressurisation unit and guides said refrigerant to the inlet side of the intake-side evaporator. The variable-throttle mechanism adjusts the flow rate of the refrigerant flowing in the bypass passage. The intake-side depressurisation unit changes the throttle aperture so that the superheat degree (SH1) of the refrigerant on the outlet side of the intake-side evaporator approaches a predetermined reference superheat degree (KSH1). The variable-throttle mechanism has the function of opening and closing the bypass passage, and opens the bypass passage if the flow rate (Ge1) of the refrigerant flowing out from the intake-side depressurisation unit is no greater than a predetermined reference flow rate (KGe1).
