Abstract

In refrigeration cycle devices having a double vibration isolation structure, when an electronic component that drove a compressor motor was placed on a vibration isolation platform and an electronic component that performed other control was fixed to a casing, the vibration state of the two electronic components was problematic, in other words, a difference would occur in displacement, causing stress on the wiring. In this invention, a compressor (1) is arranged with interposition of the bottom member (20a) of a frame (20), a second elastic member (24), a platform (21), and a first elastic member (23), and is arranged such that a first electronic component (31), which drives the compressor motor, and a second electronic component (32), which performs other control, are fixed to the platform (21).

Abstract

Various settings used in a process proceeding in line with a flow chart are reset (S100). An oxygen current (Inew) is measured (S101). A slope of the oxygen current is obtained (SA). A determination is made as to whether or not the slope can be considered to become stable (SB). A first measuring time is determined (SC). In order to determine the stability of the slope, the oxygen current (Inew) is sequentially measured and the slope of the oxygen current is updated until the slope is determined to become stable. When the slope is determined to become stable, the first measuring time is determined (SC). When the slope is not determined to become stable, the oxygen current (Inew) is further measured.

Abstract

The present invention provides a heat exchanger unit (5) that can appropriately inhibit freezing of a heat exchange element (11), even in cold-climate regions. The heat exchanger unit (5) performs heat exchange and ventilation between an indoor space (SI) and an outdoor space (SO), and is therefore provided with a heat exchange element (11), a supply air passage that is routed via the heat exchange element (11), an exhaust air passage that is routed via the heat exchange element (11), a temperature sensor (51), and a control unit. The temperature sensor (51) detects the outside air temperature. The control unit executes a first freeze inhibit control mode and a second freeze inhibit control mode. The first freeze inhibit control mode inhibits freezing of the heat exchange element (11) if the outside air temperature falls below a first level. The second freeze inhibit control mode, which inhibits freezing more strongly than the first freeze inhibit control mode, inhibits freezing of the heat exchange element (11) if the outside air temperature falls below a second level (which is lower than the first level).

Abstract

A double-tube type heat exchanger has a restriction hole, formed on an inner tube, through which a refrigerant introduced into an outer tube is introduced into the inner tube while the refrigerant expands. Therefore, a part of the refrigerant introduced into the outer tube can be introduced into the inner tube from the restriction hole while the refrigerant expands. That is, the restriction hole formed on the inner tube serves as an expansion mechanism of a bypass flow. Therefore, this double-tube type heat exchanger allows an injection circuit or a super-cooling circuit to be compactly and inexpensively constructed.
