エジェクタ式冷凍サイクル、およびエジェクタモジュール
Document Type and Number:
Japanese Patent JP7119785
Kind Code:
B2
Abstract:
To provide an ejector-type refrigeration cycle which can properly change a throttle opening of a suction-side decompression part according to a thermal load of the cycle.SOLUTION: A suction-side decompression part for decompressing a refrigerant flowing into a suction-side evaporator 19 comprises a suction-side decompression device 15 constituted of a mechanical mechanism which becomes a fixed throttle when a pressure difference ΔP which is obtained by subtracting low-stage side pressure Peo being the pressure of the refrigerant flowing out of the suction-side evaporator 19 from inlet-side pressure Pni being the pressure of the refrigerant flowing into a nozzle part 14a of an ejector 14 is larger than a reference pressure difference KΔP, and also becomes a variable throttle for increasing a throttle opening accompanied by a decrease of the pressure difference ΔP when the pressure difference ΔP is not larger than the reference pressure difference KΔP. By this constitution, it is avoided that the flow rate of the refrigerant flowing into the suction-side evaporator 19 becomes short by increasing the throttle opening at a low-load operation.SELECTED DRAWING: Figure 1
