Abstract
An ejector and a refrigeration system. The ejector includes: a high-pressure fluid passage, a flow valve for controlling a flow rate in the high-pressure fluid passage; a suction fluid passage; a mixing chamber, which includes a mixed fluid outlet; a thermal bulb disposed upstream of the flow valve, in the high-pressure fluid passage or outside the high-pressure fluid passage; and an elastic diaphragm disposed in the high-pressure fluid passage, wherein a closed cavity is on a first side of the diaphragm, and the high-pressure fluid passage is on a second side of the diaphragm; the thermal bulb in communication with the closed cavity, and the thermal bulb and the closed cavity are filled with fluid; and the diaphragm is associated with the flow valve so that an opening degree of the flow valve varies in response to a change in a pressure difference across two sides of the diaphragm.
