EVAPORATOR

摘要

An evaporator includes multiple refrigerant tubes, multiple air passages provided between the refrigerant tubes, a cold storage container disposed in the multiple air passages, and a temperature detector. The evaporator further includes a freezing allowable region and a freezing unallowable region that is provided above the freezing allowable region. The cold storage container has a small thickness region and a large thickness region that is positioned above the small thickness region. The large thickness region demarcates a smaller space with the refrigerant tubes than the space demarcated between the small thickness region and the refrigerant tubes. The small thickness region of the cold storage container is positioned within the freezing allowable region, the large thickness region is positioned in the freezing unallowable region, and the temperature detector is disposed in the freezing allowable region.

主权项

1. An evaporator comprising:
a plurality of refrigerant tubes each of which extends in a vertical direction and has a refrigerant passage, the tubes being disposed parallel to each other; a plurality of air passages provided between the refrigerant tubes; at least one cold storage container disposed in a subset of air passages of the plurality of air passages and containing a cold storage material; a temperature detector that detects a temperature; and a freezing allowable region in which freezing of condensed water is allowed, and a freezing unallowable region in which the freezing of condensed water is not allowed, the freezing unallowable region being provided on an upper side of the freezing allowable region, wherein the cold storage container includes a first region that defines a relatively large space with the refrigerant tubes for promoting of drainage of the condensed water, and a second region that is positioned on an upper side of the first region and defines a smaller space with the refrigerant tubes than the space defined by the first region, the first region of the cold storage container is positioned within the freezing allowable region, the second region of the cold storage container is positioned within the freezing unallowable region, and the temperature detector is disposed in the freezing allowable region.
