Abstract
An electric component unit in an outdoor unit of a refrigeration apparatus, includes: a first electric component; a first chamber that houses the first electric component; a second electric component; and a second chamber that houses the second electric component. The first chamber has a higher degree of hermetic sealing than the second chamber.
Claims16
An electric component unit in an outdoor unit of a refrigeration apparatus, the electric component unit comprising:
- a first electric component;
- a first chamber that houses the first electric component;
- a second electric component;
- a second chamber that houses the second electric component;
- and
- a partition plate separating the first chamber and the second chamber, wherein
- the first chamber has a higher degree of hermetic sealing than the second chamber, and
- the partition plate has an opening that connects the first chamber and the second chamber.
An electric component unit in an outdoor unit of a refrigeration apparatus, the electric component unit comprising:
- a first electric component;
- a first chamber that houses the first electric component;
- a second electric component;
- a second chamber that houses the second electric component;
- a first wire;
- a terminal block connected to the second electric component through the first wire;
- and
- a third chamber that houses the terminal block, wherein
- the first chamber has a higher degree of hermetic sealing than the second chamber, and
- the second chamber has a higher degree of hermetic sealing than the third chamber.
An electric component unit in an outdoor unit of a refrigeration apparatus, the electric component unit comprising:
- a first electric component;
- a first chamber that houses the first electric component;
- a second electric component;
