Abstract:
1. An evaporator unit comprising: a first heat exchanger configured to perform heat exchange between refrigerant flowing thereinto from a refrigerant inlet and air; a bypass passage through which the refrigerant flowing from the refrigerant inlet flows while bypassing the first heat exchanger; a second heat exchanger configured to perform heat exchange between air and mixed refrigerant in which the refrigerant after passing through the first heat exchanger and the refrigerant having passed through the bypass passage are mixed; and a flow amount adjustment portion configured to adjust a flow amount of the refrigerant flowing through the first heat exchanger and a flow amount of the refrigerant flowing through the bypass passage; wherein the flow amount adjustment portion includes a fixed throttle; the first heat exchanger includes a plurality of tubes for allowing the refrigerant to flow therethrough, and a tank for distributing the refrigerant into the tubes and collecting the refrigerant from the tubes; the flow amount adjustment portion is disposed in the tank; an internal space of the tank is partitioned into a distribution space for distributing the refrigerant into the tubes, and a collection space for collecting the refrigerant from the tubes, and the first heat exchanger has a refrigerant outlet side configured to be in communication with an inlet side of the second heat exchanger via the collection space, the evaporator unit further comprising an introduction pipe located in the distribution space to introduce the refrigerant flowing through the bypass passage into the collection space, wherein the flow amount adjustment portion is integrated with the introduction pipe.
