Title:
エジェクタ式冷凍サイクル
Document Type and Number:
Japanese Patent JP6939691
Kind Code:
B2
Abstract:
An ejector-type refrigeration cycle (10) comprising a compressor (11), a radiator (12), a high-stage-side pressure reduction unit (14a), a high-stage-side evaporator (15), a low-stage side pressure reduction unit (14c), a low-stage-side evaporator (18), a branching unit (13a), and an ejector (16). The branching unit (13a) divides a refrigerant flow downstream from the radiator (12), causing one divided flow of refrigerant to flow toward the high-stage-side pressure reduction unit (14a) and another divided flow of refrigerant to flow toward the low-stage-side pressure reduction unit (14c). The ejector (16) has a pressure-increasing unit (16a) that draws in, from a refrigerant intake opening (16c), the refrigerant flowing from the low-stage-side evaporator (18), increases the pressure of a mixed refrigerant comprising an injection refrigerant and the indrawn refrigerant, and causes the mixed refrigerant to flow toward the intake-opening side of the compressor (11). In addition, the ejector-type refrigeration cycle (10) is equipped with an enthalpy adjustment unit (14b, 17) that lowers the enthalpy of the refrigerant flowing to the low-stage-side evaporator (18).
