Single-package air conditioner

A single-package air conditioner comprising:

• a housing;
• and
• a removable cooler/heater unit housed in the housing,
• wherein
• the cooler/heater unit includes a blower fan casing;
• and
• a component forming part of the blower fan casing is removable, such that when the component is removed an opening provides sufficient access to enable removal of a fan provided inside the blower fan casing.

A single-package air conditioner comprising:

• a housing;
• a cooler/heater unit housed in the housing;
• and
• heating means, arranged inside the housing, for heating,
• wherein
• the heating means is removable through either of left-hand and right-hand side faces of the housing.

A single-package air conditioner comprising:

• a housing;
• and
• a cooler/heater unit housed in the housing,
• wherein
• a hermetic connection portion is formed between a vent opening formed in the housing and the cooler/heater unit.

A single-package air conditioner comprising:

• a housing;
• an indoor heat exchanger, housed in the housing, for exchanging heat with air inside a room;
• an indoor blower, housed in the housing, for blowing air into the room;
• an indoor air passage, housed in the housing, through which wind produced by the indoor heat exchanger is passed;
• an outdoor heat exchanger, housed in the housing, for exchanging heat with air outside the room;
• an outdoor blower, housed in the housing, for blowing air out of the room;
• an outdoor air passage, housed in the housing, through which wind produced by the outdoor heat exchanger is passed;
• and
• a partitioning member for partitioning at least part of the indoor and outdoor air passages,
• wherein
• the partitioning member has a portion thereof formed into a curved-surface portion for guiding the wind passing through one of the indoor and outdoor air passages, and
• wherein the curved-surface portion is structured as a diffuser portion for diffusing the wind passing through the other of the indoor and outdoor air passages.

• the partitioning member has a portion thereof formed into a curved-surface portion for guiding the wind passing through one of the indoor and outdoor air passages, and
• wherein the curved-surface portion faces an outdoor inflow opening, and has an arc-shaped section whose radius R satisfies
• min(Ra,Rb)≧R,
• where Ra represents a dimension of a portion of the outdoor inflow opening facing the partitioning member and Rb represents a dimension of the outdoor air passage.
